Ark, I became an NPC in the online game

It was also there that they learned that the Sarkaz race was discriminated against by the Terrans. Some of the originally kind-looking merchant drivers immediately changed their expressions after seeing Yang YanXF and several Sarkaz players, and got into their cars and left while cursing.

In the end, the few people walked to the countryside and paid for a ride before they arrived in Leitania.

Indeed, considering that I might have to travel more places with the Trailblazer in the future, it makes sense to buy a vehicle. It's not possible to ride in the Trailblazer every time, right?

"If you have a vehicle, you can travel with me for a while." Xia Yuan said with a smile.

He didn't say anything final, he just said that he would travel for a while - after all, players have their own considerations, and if they get tired of it one day, they can leave. If there is an emergency, he will have a reason to leave early.

The players were all delighted when these words came out, some even wanted to go up and give the Trail Blazer Giegie a loving hug, luckily they held back, otherwise the Trail Blazer's favorability would have dropped.

Xia Yuan and ten players agreed to meet here in the evening, so he left immediately to let them move freely.

The cost of a vehicle is neither cheap nor too expensive. A pickup truck that can carry a lot of cargo can be purchased with hundreds of thousands of Longmen coins, but one needs to think twice before purchasing a vehicle that can drive in all kinds of weather... Moreover, they have just spent a lot of money, and it is impossible for each of them to own a vehicle.

The only car shop in the Novice Town of Leitania sells off-road vehicles, which is also an option for players. In the end, the players pooled their money and Magic ZX, Egg Knife Egg Tart, Qiu Muyu and Xiao Xiao Ice Cream jointly bought one, Yang Yan XF and three members of the strategy team jointly bought one, and two high-level players from the game guild jointly bought one.

Owning a car of their own for the first time means being able to drive freely on this land in the future and go wherever they want. It’s exciting just thinking about it, not to mention that each car has its own different modifications. They have already imagined how cool it would be to put protective armor on the off-road vehicle.

In the evening, Xia Yuan came back from a stroll and found three off-road vehicles on the side of the road. Players were excitedly touching and climbing up and down the vehicles, and he couldn't help laughing. He coughed, attracting the players' attention, "Adventurers, are you going to wait here for a month, or go back with me to the nearby mobile town and live there for a month?"

The ten players' eyes lit up when they heard this. Isn't the mobile town much better than the novice town? They have all seen the video of the Great Knight Leader introduced in Magic ZX. They were shocked by how majestic and huge the mobile city was. If they could see it with their own eyes in version 1.0, they would have no regrets.

All ten players voted unanimously in favor.

Xia Yuan smiled slightly and said, "When we enter the city later, you all need to say that you are my subordinates, so that your identities will not be checked."

"understand!"

The convoy drove out of the town, its wheels rolling over the ground. The driver of the Magic ZX convoy was Dan Dao Dan Tart, who had passed the driving test in real life. He stretched his body, opened the window, followed the pickup truck in front, and shouted with a smile: "Wuhu, it feels good. I finally start traveling with my fate god again!"

The SUV next door: "Go, go, go! Let's go through this land of suffering!"

The SUV on the other side: "Yuan Shen! Start!"

Chapter 81 Professor Naumann

The players drove off-road vehicles into the Leipzig mobile town. When checking their identities at the border, several players were questioned by the Leitanian guards, but Xia Yuan easily solved the problem by just scanning their faces.

"This... this is a moving city."

Players who had never entered a moving town before sighed in their voices. They had only seen it in Magic ZX teacher's videos before, and felt that the city walls were tall and shocking... But the feeling of seeing a moving city with your own eyes is different. The feeling of being oppressed by this giant made some players feel suffocated, as if they would be crushed to the ground by this huge city in the next moment.

The members of the strategy team sighed with emotion. Yang YanXF patted the steering wheel lightly. He always felt that this issue of Terra Daily had something to write about. Not to mention Terra Daily for the time being, he felt that Yan Fei was a bit at a disadvantage. Can the tasks in the Novice Town be compared with those in the Mobile City? As long as you can sneak in and do any task, it’s a big profit.

As a UP host who likes to interpret stories and part-time writer and host of Terra Daily, Yang Yan XF can't wait to enter the library and find out. He is very curious about everything in this world. Although players have been in Terra for nearly two years, not much of the background story has been dug out.

The players stayed in a hotel near the outer city, where the price was relatively cheap. They had free time in the rest of the time. Xia Yuan just gave them a few exploration tasks, asked them to talk to a few people on the street, search for the history of Leithania, and then left. He acted more alone here and did not need the help of the players.

This also hits the G-spot of players. They like to travel with famous NPCs and join the factions they love, but sometimes they also want free time - in fact, every faction in Terra will give the company's employees free time, but currently players have too little exposure to it.

Xia Yuan would naturally imitate their appearance. The company he is imitating now is Black Steel International. Apart from missions and taking them on trips, he spends most of his time doing his own things.

The players immediately split into several teams. The two girls from the Production Department went shopping, Magic ZX and Egg Knife Egg Tart followed them. Yang Yan XF and the members of the Strategy Group went to talk to the NPCs honestly and try to understand the history of Leithania, while the two high-level players formed a team and began to try to take on some bounty missions.

They are located in a mobile town, where the twelve towers belonging to the Leithanian nobles are not built. However, this is a good thing for players because the economy of the mobile town is very developed and there are many things to buy.

Magic ZX had previously gotten in touch with Yang Yan XF. As both of them are UP hosts who follow the pioneers, their video styles and content go in two different directions. Magic ZX is more responsible for making comments during the journey, while Yang Yan XF is more responsible for interpreting the background of the story, etc. However, there is one thing that they are similar in: they both make guides and have collaborated on a project before.

"Wow, these are staves in the shape of musical instruments."

Dan Dao Dan Tart took a few steps forward and looked at the staffs displayed in the store that Xiao Xiao Xue Gao pointed to... They were indeed exactly the same as the musical instruments, and the price was not cheap.

"You are tourists, right?" The boss saw that Xiao Xiao Ice Cream's race was Sarkaz, but he didn't care too much. He said cheerfully, "Our musical instrument manufacturing and magic supplies manufacturing industries in Leitania are very developed. You can buy musical instrument-shaped staffs here, and you can even play them."

As expected, every place has its own specialty. Casimir is a competition of different types of knights, while the land of Leithania is a combination of musical instruments and spells.

No one wanted to buy it. They were not sorcerers. Would they buy it to smash someone's head with it?

The players began to go shopping in the night. Xia Yuan returned to his residence and was overjoyed to find that Senomi had prepared dinner for him. He patted Senomi on the head a few times, making Senomi blush and giggle. As for what he had done today, Sister Jian already knew it. After he drove out with a fully loaded pickup truck, she could guess that the boss had gone to contact the adventurers.

She has gradually figured out the boss's way of doing things. She has been walking around this land with the boss for a while, and the boss is the only one who looks at these players differently. Is it because the boss has a good eye for talent?

Jian thought this might be the case, because she sometimes attended the sales and resource management classes that Xia Yuan taught to Senomi. She had always been a black knight fighting on the field, so she was a little unfamiliar with this knowledge, but she mastered it much faster than a child.

I found that the boss didn't make much money doing business with them, but he won because there were so many adventurers. Even if he didn't make much money from each order, he won because there were so many adventurers...

During the break of dinner, Xia Yuan took another look at Mandela's current learning progress and found that she was writing the Originium formula carefully, stroke by stroke. Xia Yuan felt a little dizzy and simply stopped looking at it. Whoever wanted to be a warlock could be one.

The next day, Xia Yuan and Jian sent Senomi and Mandela to school and then separated again. Jian wandered around collecting intelligence information, while Xia Yuan went to Leithania William University.

Just like at Longmen University of Technology, Xia Yuan convinced the security guard by saying that he wanted to enroll in the school next year. Perhaps because of his high charm, he walked into the university and headed towards the library.

There was the knowledge he wanted to find. What he wanted to find were not all books about main and secondary professions, but books related to academics. He took a book about ecosystems from the shelf and took out a water cup at the same time. "Muir Seth, are the books here helpful to you?"

"You called me out just to read a book, Xia Yuan, you're so boring." Muirseth turned into a water clone and appeared beside Xia Yuan, with a hint of helplessness on her face. However, chatting with Xia Yuan was more interesting than writing a report in the ecological park. She took the book from Xia Yuan and said, "Let me see."

Muirseth looked at it for a while, focusing on the annotations on the textbook. Seeing that she was immersed in it, Xia Yuan took a book about the natural environment and source stone from the bookshelf and started reading it as a textbook.

Originium is the source of pollution for this earth. The textbooks analyze which ecological environments Originium can affect. For example, it can cause plants near Originium to wither and rot, and rarely mutate, but the ultimate result is still extinction. It can also pollute water sources, affecting plants and animals that rely on water for survival. Animals may become infected organisms, and plants may directly parasitize.

The textbook also specially marked "Terra's naturally occurring disaster system" in red pen. Among them, the sandstorm in Kazdel was the most familiar to Xia Yuan. In his previous life, he had also seen natural disasters such as volcanic eruptions and meteorite pillars from afar. This was the first time he heard of the term "natural disaster system" and he couldn't help but continue reading with interest.

A very interesting point was mentioned, “positive feedback loop”.

What is a positive feedback loop? It is a process in which the output of a system enhances the original input, forming a loop that continues to grow or amplify. These are all terms, and to explain in layman's terms, lake water pollution -> fish and other aquatic plants and animals die -> bacteria decompose -> pollutants float on the water surface -> lake water oxygen content decreases -> aquatic plants and animals die, anaerobic bacteria in the water continue to increase -> decomposition accelerates, temperature rises -> lake water pollution intensifies.

Positive feedback instantly amplifies pollution, creating a vicious cycle.

Natural disasters can be regarded as pollutants, and Terra as lake water. At this point, the picture becomes much clearer.

The article mentions that Originium has the characteristic of mutual attraction, and the higher the density, purity, and volume of Originium, the stronger the attraction. Research shows that natural disasters may actually be a medium for the spread of Originium.

Some places that have been hit by natural disasters will grow huge black crystals, which are Originium crystals.

However, in order for Originium crystals to reach the same growth rate as when a natural disaster occurs, the total density of Originium dust in the nearby air must be very high or they must be in direct contact with a large amount of Originium dust. Therefore, based on these and the mutual attraction of Originium, the book speculates that natural disasters contain high-density Originium crystals, such as volcanic eruptions, where the magma of the volcano has a high content of Originium crystals.

In reverse, it can be concluded that the high-density Originium crystal particles and dust in the environment caused the outbreak of the natural disaster. High-density, purity, and volume Originium crystals will gather nearby Originium particles/dust, increasing the density of nearby Originium, so we can re-summarize it.

Xia Yuan was dizzy, but finally understood it. At least the notes in the book boldly speculated the cause of the natural disaster.

Among them, the one that Xia Yuan found familiar was Kazdel. This country was closely related to natural disasters, which came every now and then. The Sarkaz mercenaries in Kazdel had gotten used to it, but this land had not yet gotten used to it. Could this be substituted for the positive feedback loop mentioned in the book?

“Well…it’s a little different from what is taught at Tremont University, but the content is very interesting.”

Muirseth said seriously.

Xia Yuan nodded and handed the page he had just read to Muirseth. Muirseth read it for about five minutes and then said, "This is very close to the topic I studied before. The inference is very bold and the argument is profound... I don't know who wrote it."

Xia Yuan didn't know the answer either, so he went to the front desk to ask the librarian who wrote the notes on the book.

"Are you new students? The notes in this book were written by Professor Nauman."

"We are indeed new students, Professor Nauman?"

The librarian quickly corrected the question, "There are two Professor Naumanns at William University. The one I'm talking about is a lady. Her full name is Professor Magna Naumann. She is an expert in natural environment and ecosystem research. The book in your hands is Professor Naumann's personal notes. You are lucky to have it... because Professor Naumann's personal notes are a treasure for every student."

Xia Yuan thanked him and glanced at Muirseth. "Are you going to meet Professor Nauman as an ecology graduate?"

"Xia Yuan, do you know how distressed I was when I was writing my graduation thesis?"

Muirseth pouted, as if remembering the painful meeting, and the water clone trembled, "Woo, woo, woo, woo, life was playing tricks on me, a cute and pitiful elf, every day. If I hadn't been calm enough, I might not have graduated yet."

"It's not that exaggerated." Xia Yuan, who hadn't seen Muirseth pretending to be pitiful for a long time, suppressed his laughter.

Muirseth reached out his hand and poked his face, snorting unhappily. "I'll tell Christen that you want to attend Tremont Polytechnic University in a moment. I'm sure she will be happy to write you a letter of recommendation. I really want to see how you, Xia Yuan, write your graduation thesis then."

Xia Yuan's face suddenly fell. Damn it, I've already been hurt once in the real world, and I have to go through it again by becoming an NPC in the game, right?

Join the group chat "write 100 words a day" and try to finish a sci paper within a month, right? Don't tell him that he still needs to check for plagiarism when the time comes, or his gray hair will probably turn white overnight.

"Hehe, Xia Yuan, why do you have this expression? Are you really scared?"

Muirseth chuckled, then walked forward a few steps, put his hands behind his back, and turned around. "Thank you. If I have the opportunity to ask Professor Naumann for advice, it will be an inspiration for my research."

Xia Yuan nodded, "It's almost time for get out of class to end. Let's go wait for her near the teaching building."

The campus bell began to ring, and the university building became lively. The two stood aside and found that dozens of classmates came out surrounded by several professors. Among them, only one was a woman, a Caprini with brown curly hair, about forty years old, and looked quite scholarly.

She talked to the students for a few words and walked towards here as if she had finished today's class. Before she got close, she looked at Muerseth and said, "The feeling of casting a spell... classmate, you used water... No, what Originium technique did you use? No... It doesn't seem to be an Originium technique either."

As soon as the word "classmate" came out, Muirseth seemed to have returned to the school days of the poor little elf. She trembled all over, "Um, that... this is my water clone..."

“What a delicate control.”

Professor Naumann praised. She walked forward and circled around Muirseth a few times, smiling. "Excuse me, my husband should be very interested in your spell. I am Professor Magna Naumann. You seem to be strangers. Are you freshmen who are here to visit?"

"Ah... no." Muirseth took a deep breath, and after discarding her fear of the professor, she politely saluted Professor Nauman, "Hello, Professor Nauman, I am a graduate of Ecology from Columbia Polytechnic University Tremont. My name is Muirseth. I saw your notes in the library by chance. I am very interested. I wonder if you have time to explain some academic issues to me. I don't understand some of the things you wrote."

Professor Nauman smiled and said, "Well... I don't have any classes this afternoon, so of course you can come with your boyfriend. It will be nice to have an extra audience."

Although Muirseth was a water clone, he could still see that she was a little shy, "No... not my boyfriend."

But her voice was too soft. Professor Naumann had already walked quickly forward, and halfway through he turned back to signal them to follow.

Xia Yuan laughed, and several water bombs flew up from beside Muirseth and hit him.

"You're still laughing, you're still laughing!"

Chapter 82: Do you understand the value of an expert secondary profession?

After the two people who were misunderstood by Professor Neumann went to the office, Xia Yuan came forward to explain. Professor Neumann smiled and said nothing. Although she felt that she was wrong, the atmosphere between the two was indeed very harmonious, and they looked like a couple.

Muirseth is a genius who skipped grades, and Nauman is a professor. Although they are not on the same level in terms of status, they have a lot in common.

Professors are very popular in Leithania, which is exactly the same as in Germany in real life. They can enjoy priority services, and when traveling, others will politely call them professor instead of Mr.

To be a professor here, one needs a doctorate degree, so Professor Neumann, who looks young, can continue to be the teacher of graduate Muir Seth in both theory and practical operations.

Muirseth was talking to Professor Nauman about the relationship between weather and Originium. As written in her book, Professor Nauman and his wife were conducting a field survey of the volcano. Not to mention the past, there had been volcanic eruptions in the past few years. The sight of Originium being ejected was even more terrifying than a sandstorm. Volcanic ash and Originium dust covered the sky, blocking the sun, and the entire land was plunged into darkness.

Then, the heavily infected Originium dust began to fall. If it came into contact with the skin, it would definitely cause infection. If it entered the lungs through breathing, the infection would become more serious and there was a high possibility that one would die.

"—— Comparing the size of the attraction of a single Originium and the effect of the distance on the size of the attraction, it can be clearly seen that the distance has a greater impact on the attraction. This is why cities on this land are more likely to attract natural disasters, because compared to natural Originium veins, not only are all the Originium crystals used in cities on the surface, they are closer to the Originium crystal particles in other mobile environments. In addition, compared to natural veins, the Originium in cities is distributed over a large area, throughout the city, which makes it easier for Originium crystal particles and dust in the environment near the city to accumulate, making it more likely to cause natural disasters."

Nauman was discussing with Muirseth why natural disasters often occur near cities. "Natural disasters are actually very common on this land. Compared with natural Originium veins, it is concluded that cities are more likely to attract natural disasters. But this does not mean that natural Originium will not attract natural disasters. It's just that the frequency may be lower than that of cities."

"Even if there are no large Originium crystals, the Originium crystal particles in the natural environment may still naturally gather. This is why natural disasters will not land alone near the mobile city."

Muirseth thought for a while, then asked, "Professor Nauman, if we don't use Originium technology, will the probability of attracting natural disasters be lower?"

Professor Naumann shook her head and sighed, "We have had this view before, but the conclusion we reached is that even if we don't use Originium technology, there will still be natural disasters. Since it doesn't matter whether we use it or not, we might as well continue to use Originium technology. Judging from the results, this method is indeed successful. If we had never used Originium technology, the mobile city would not exist, and the arrival of natural disasters would leave us nowhere to hide."

"After we used Originium technology, natural disasters occurred more frequently. However, because we invented mobile cities, we were able to almost completely avoid natural disasters."

Xia Yuan was impressed. This is a scholar in the field of natural disasters and nature. This is what it means to listen to a word from a master. When he was a player in his previous life, he didn't care about natural disasters, nor did he think about the significance of this phenomenon. He just avoided it. But after becoming an NPC and becoming a part of this land of suffering, Xia Yuan felt that this trip was not in vain... He felt that it was very profitable to listen to Professor Neumann's words.

[Professor Magna Naumann Lv40 is teaching you the skill [Disaster Systems], the current progress is 0.03%, and the progress of unlocking the Ecologist sub-profession is 0.01%]

Damn, I didn't expect that listening to your words is actually equivalent to learning a skill. There is actually an ecologist sub-profession... It seems that someone unlocked it when studying in college in the Ark in the previous life. It is one of the rare sub-professions that not many people take.

However, the skill of learning the disaster system is quite useful. In addition to delivering messages alone, the messenger also has a more powerful promotion sub-profession, the disaster messenger. The condition for becoming a disaster messenger is to learn the disaster system.

The main job of the Scourge Messengers is to observe the Scourge and give early warnings to surrounding cities. The Scourge Messengers will also communicate with each other to exchange information. However, the Scourge Messengers are very likely to be infected with Ore Disease, because Originium often appears in large quantities in the Scourge. The Scourge Messengers who often deal with the Scourge have an almost 100% chance of contracting Ore Disease.

Muirseth seemed to admire Professor Nauman very much. She began to introduce the research project she was currently in charge of, hoping that Professor Nauman could give her some advice or two.

The lecture lasted until the afternoon. Xia Yuan sat aside and listened, and found that the system was still giving constant prompts.

[Muirseth Lv60 is teaching you the skill [Ecology], the current progress is 0.16%, and the progress of unlocking the ecologist sub-profession is 0.06%]

Well, listening to the two people talking, the experience bar was also increasing. Xia Yuan decided to attend Rhine Life's meetings every day next time. He would not do anything else and just listen to the scientific researchers exchange projects.

There was a knock on the door, and then it was pushed open. Standing outside the door was another Caprini with fluffy brown hair. He was wearing a respectable faculty uniform and glasses. Seeing how lively the office was, he smiled.

"Ah... Sorry, Katia, I lost track of time while I was talking."

Professor Magna Naumann smiled apologetically, and she stood up and introduced to Xia Yuan and Muerseth, "This is my husband, Katia Naumann. He is also a professor at William University, a professor at the Originium Academy of Arts, and a mentor for trainees."

"It's an honor to meet you, Professor Naumann. My name is Xia Yuan, and I'm a messenger. I've heard that there are two famous Professors Naumann in William University, and I got to meet them both today."

Xia Yuan stood up with a smile. His legs were really numb from sitting so long, but it was impolite to leave the table without permission while two people were talking, so he would not miss the chance to stand up... Although his skills were improving little by little, his butt was numb and he felt a little drowsy, just like he was in math class. He couldn't tell what the teacher was talking about because he kept opening and closing his glasses.

If the experience bar hadn't been rising, he would have thought he had fallen into a deep sleep and was daydreaming.

But he still forced himself to listen. After all, as an NPC on this land, his profession and secondary profession were one thing, and knowledge was priceless.

"Hello, I'm Katia Naumann. Xia Yuan, you're interested in ecosystems and natural disaster systems at such a young age. Our knowledge will surely be passed on to future generations."
