My system comes with a chat group?

Yakumo didn't completely agree with Celia's words. Besides, as long as the attack was strong enough, defensive magic would be penetrated by magic.

"The best way to deal with it is to combine the two. Of course, if solid substances are used, it would be redundant, and the use of liquid substances would also be limited by whether there are enough materials on hand."

"So, why not use gas?" Yakumo had tried it before, such as the most popular nitrogen armor. But simply compressing nitrogen seemed not enough, and it needed a support.

Because the gas itself is invisible, even if Yakumo can make some associations, he cannot perfectly control the gas. So Yakumo came up with the idea of ​​attaching nitrogen to the defensive magic to create a double layer of defense.

"The gas with the largest component in the air is also the easiest to use. Since everyone has thought about using land and water, why hasn't anyone thought about using air?" Yakumo asked back.

"..." Celia was stunned for a moment, then she grinned: "If Volame hadn't passed away, I really want Volame to meet you. Maybe her ideas will change."

"Not at all." Yakumo said without hesitation: "Volame and I are essentially the same kind of people. I might also want to stop popularizing magic so quickly, but that's because I'm worried that humans will use magic to kill each other."

"But, if there is no magic, will humans not fight and kill each other? Obviously not. Just because of this, treating the popularization of magic as a scourge is the greatest possibility of killing magic."

Hearing what Yakumo said, Celie's face immediately fell again: "So, the magic you like... isn't it also the magic that creates flower fields?"

"Yes." Yakumo sat cross-legged on the ground: "It's just that the reason why I like this magic is different from that of Volame because it was taught by my parents and Frillian. I like this magic simply because it can stop people from being hungry."

"I don't have the same romantic ideas as Volame and Fulilian. Most of the time, I am still very pragmatic." Yakumo smiled and replied: "Or maybe the gene of farming is deeply engraved in my body."

"I really don't understand you guys..." Celia leaned on the armrest of the chair, somewhat uninterested: "Whether it's Volame or you, you are both geniuses. You guys should have reached a higher level."

"As it turns out, Volame has been dead for many years, and Fulilian is still only a half-baked one. I don't think Fulilian can successfully defeat the Demon King. Someone like that has no chance of winning against the Demon King."

"Maybe. Maybe if Fulilian faces the Demon King alone, she will lose miserably. But Fulilian is not alone. Xinmeier, Aize, Haita and me, each of them is an indispensable member of this team."

"What a pity, to waste one's talent on something like this..." Celia was still somewhat dissatisfied. After so long, no one could reach her level of magic. It was a pity no matter how she thought about it.

"It's good to do the right thing at the right time, isn't it?" Yakumo smiled and spread out his hands.

A piece of defensive magic. Then attach nitrogen to the surface of the defensive magic.

Simply attaching it is definitely not enough, some compression is also required. A tighter nitrogen defense can resist stronger and more penetrating attacks, and can also make the defensive magic more powerful.

However, this magic may only be understood and used by Yakumo himself for the time being. It is still difficult to let this era understand that the components of air include oxygen, nitrogen, carbon dioxide, etc.

Even if I tell them, they will probably ask me how I came to the conclusion of more than 70%. I can't understand it, I can't imagine it, I can't take the first step of magic.

"You really don't want to stay?" Celia tried the strength of the defensive magic after Yakumo's modification.

"Of course I can't stay here forever. Do you think I'm the kind of person who would devote my whole life to research?" Yakumo asked. There are many worlds other than Fulilian's.

It is obviously too narrow to just stop at Celia.

"Hmm..." Celia failed to pull people together again, and she became visibly depressed.

"Celia, you don't have to act so exaggerated..." Celia's expression showed that she was very sad. Yakumo never thought that Celia's reaction would be so big.

"Forget it, all of you..." Celia was about to go back to her seat, but suddenly she thought of something: "Two months later, when you go to the next city, remember to submit your research on killing magic and defensive magic."

"When the time comes, they will issue you a certificate of a great magician. With this certificate, it will be much easier for you to continue traveling north."

Chapter 100: The Team's Survival Method

While Yakumo was discussing with Celia, the rest of the Sinmeier team was not idle either. Since there were no commissions nearby, they headed to the next city to have a look. Anyway, the next city was not too far away and they would arrive there soon.

"So, this knife actually went so far." Xin Meir looked at the kitchen knife in his hand, which was a little too big. The carvings on it were very delicate and beautiful, and the blade was also quite sharp.

"It took us half a month to get a kitchen knife from a restaurant chef..." Fulilian also felt exhausted: "If the food in this restaurant is not delicious, it will feel like a loss."

"A chef who uses a knife like this to cook should be worthy of the knife's value. A knife is like a proof of a magician's strength. A chef who doesn't have enough strength will be laughed at if he uses a knife like this." Haita replied.

"Hmm? I hope so." They traveled a long way to find this kitchen knife. The kitchen knife was indeed stolen, after all, it looked very valuable.

But the problem was that after it was stolen, when the thief tried to sell it, it was snatched away by a wild beast. The thief was afraid of being discovered, so he chose a place outside the city. In this way, the kitchen knife ended up in the forest.

But that's not all. The kitchen knife was found by a red dragon. Dragons like precious metals and shiny things very much. Then the kitchen knife was snatched away by the red dragon and placed in its lair.

As a result, Xin Meier and his team found the lair of the red dragon and killed a dragon. After that, they found a kitchen knife in the lair of the red dragon, and also got some treasures and magic books.

"As usual, the proceeds are with Yakumo." Xin Meier handed the purse to Yakumo: "Also, we packed up the hotel chef's food for you. It's really delicious..."

“Since everyone says so, it must be very delicious.” Yakumo took the purse and the food, planned the pocket money for everyone, and then handed the pocket money to them.

Because Yakumo built a three-bedroom, one-living-room wooden house here, everyone saved money on hotel accommodation over the past few months.

"Hmm, it's really delicious." Yakumo took a bite. There was no doubt that this chef's cooking skills were much better than his, and there was nothing wrong with admitting that.

"Right? I remember that you, Yakumo, also have some preferences for rice, so I told the chef to add omelette rice. But I wanted you to try this steak anyway, so in the end I just made it into a rice bowl." Xin Meir supported his face with one hand.

“Pfft, Omurice Donburi, what a weird combination and way of eating.” Yakumo couldn’t help laughing: “But, it’s really your style. Thanks to this, I can taste these delicious foods in their entirety.”

"This commission is really worth it." Yakumo quickly finished his meal and said, "No wonder you guys weren't here these few days. You've traveled so far. So, you've basically figured out the route ahead?"

"Yes, that's right. There's no danger on the road, probably because the number of adventurer teams has increased. It's just that some monsters will appear in the more remote places. We also cleaned up some of them when we went to find the kitchen knife."

"You must have had a hard time on this journey." Yakumo packed up the lunch box and asked, "Should I return this to the owner of the restaurant?"

"Hmm? That's not necessary. They didn't have a take-out service in the first place, but probably because we helped recover the knife, they just gave it to us."

"Yakumo, how's your progress?" Xin Meir was also concerned about Yakumo's situation.

"The progress is quite ideal." Yakumo nodded: "There has been considerable progress in defensive magic. Celia said that when we go to the next city, we can get the magician's certificate."

“It should be here next.

Continue to study with Celia. She has so much magic that I can only learn as much as I can. I don't expect to learn everything. "

"But King Daici Tree is learning here. After King Daici Tree has learned it, it will be the same for me to learn from him. This is called saving the country in a roundabout way." Yakumo said jokingly.

"If Celia knew... No, Celia should already know. But to her, none of this matters, as long as it's interesting or interests her." Fulilian interrupted.

"By the way, did Celie try to get you to stay again?"

"Yes. But I don't know if it's because we've been isolated from the human world for too long, Celie's way of inviting is very strange." Yakumo complained: "If I don't analyze it several times, I won't even realize that it's an invitation."

"She has always been this awkward. But it seems quite fun to have been rejected several times in a row. What a pity, why can't I go to her place again..."

"If you go there again, maybe Celie won't allow you to see her for a thousand years." Yakumo also complained.

"Okay, now that we've had enough jokes and eaten, let's start planning for the next two months, shall we?" Xin Meier spread out the map on the table: "We are in this position now."

"We have been to the city ahead. It is relatively safe and peaceful there. We don't need to worry too much." Xin Meier suggested: "After Yakumo's affairs are over, how about we stay in the city for a day to buy supplies and then leave directly?"

"Okay, I have no objection." Yakumo nodded. They had already obtained a lot of magic books from Celia, so there was no need to waste too much time in the city. This was already the third year since they came out, and they hadn't even reached the halfway point of their journey.

"We have no objection either," Haita and the others said. Even Fulilian had no objection. She herself was a little uncomfortable being near Celia, so she decided to leave early.

No, if she hadn't wanted to bring Yakumo with her, she might not have come to see Celie at all.

"Then, we will cross the city and head to the northern plateau. When we enter the northern plateau, it will be almost summer to autumn, and the climate will be more suitable, and we won't encounter blizzards."

"It seems that staying here for three months is a wise choice." Yakumo answered happily.

"Indeed, according to the information I heard, there are occasional snowy days in the northern plateau even in spring. After entering summer, the snowy days completely disappear. It is not until the end of autumn that snow starts to fall again."

"Besides, the further north you go, the worse the weather will be. I'm sure you've all seen the snowstorms before. When you enter the northern plateau, I hope you can take good care of yourselves and don't let yourself get hurt by the weather."

"Not only that, the northern plateau has to deal with more than just the climate." Fulilian interrupted: "Once you enter the northern plateau, there will be more and more troublesome monsters."

Chapter 17: Celia: I was shocked twice (31/)

"Generally speaking, when heading to the northern plateau, a monk is a must in the team." Fulilian introduced, "Because after entering the northern plateau, there will be more and more troublesome monsters."

"Many monsters have the ability to seduce people. For example, a monster called Phantom Ghost will create the person that people want to see the most, thereby seduce humans and eat them."

"There are countless monsters like this, so it is important to have a monk who can remove curses in the team. Secondly, the existence of magicians is also very important, so you can see so many magicians here."

"So there is another reason." Xin Meier propped up his chin. "But in this case, our team is already complete, right? Whether it's monks or magicians, our team is complete."

"That's true, so our team doesn't need to worry about anything." Frillian nodded, then looked at Yakumo a little embarrassedly: "Um, Yakumo. Did you get any interesting magic books from Celia?"

"The magic books are okay..." Although Yakumo looked speechless, he still took out two magic books from his backpack: "This is what I copied from there. It's not a damage-type magic book, but it's quite interesting."

"That's exactly what I need." Fulilian took it carefully and rubbed the magic book with her face: "I don't need those magic books that can only be used for fighting and killing."

"How about Yakumo, you learn some magic to copy books, and then we can go steal Celia's library?"

"Ah...Frilian, calm down. If Celia gets angry, I can run away, but can you?" Yakumo didn't believe that Frilian could outrun Celia. She might be pulled back before she could take two steps.

"That's true." Fulilian said with some regret: "Then there's nothing we can do. You better do your best during this period."

"I didn't expect you to work together..." Yakumo sighed, "Anyway, I'm studying defensive magic lately. I'll teach you when I'm done with it."

"Xin Meier, you should pay more attention to the movements of the other seven sages recently. It would be good if you can kill as many of them as possible. Although I don't know how much help this will be in defeating the Demon King, it can at least make things easier for the ordinary troops here."

More importantly, the Seven Bengxian

It gives a lot of experience.

"Don't worry, I will seriously consider and implement this aspect." Xin Meir is still very reliable. At least in this regard, he has not lied.

"Then I'll leave it to you. I have to go to Celie's place again tomorrow. I have an appointment with her to test defense magic and killing magic. Well, now it's called attack magic."

Just as Yakumo said, Yakumo and Celia started fighting the next day. The Great Tree King watched from the side and learned some magic combat skills.

Because it was a test of two kinds of magic, Celia and Yakumo did not move at all, but simply used magic to attack each other. While attacking, they also used defensive magic to defend.

Celia had a lot of magic power, so she didn't worry about wasting it when casting magic. After learning attack magic, Celia's first attempt was not to attack with just one move, but to cast multiple attacks at the same time, with each attacking magic at a very tricky angle.

Yakumo did not activate the magic shield, but actively used defensive magic. However, the use of defensive magic is not as easy as the magic shield. The activation and defense of defensive magic is a test of a magician's reaction and magic accuracy.

Yakumo can indeed use defensive magic, but it is still a bit difficult for him to use only one piece of magic to defend against different angles at a time. This is when Yakumo has already gained a lot of intelligence attributes.

In contrast, Celia was able to defend against Yakumo's attack while attacking. Not only did she use the single-piece defense magic with the least consumption, but she also accurately defended against attacks from every angle.

Even when Yakumo fired his magic cannons, the order of his defensive magic was consistent with the attack order of Yakumo's magic cannons. From this point alone, we can see how powerful a magician Celie is.

"As expected of Celie." After the fight, even Yakumo was a little out of breath: "It is indeed my loss."

"Haha, it would be incredible if I lost to you in such a competition." Celie didn't even use her magic wand: "But to be honest, your talent is the highest among all the people I have ever seen."

"Defense magic. Of course, it is very simple to directly deploy a defense, but that will also increase the magic power consumed. The more defense magic you deploy, the greater the magic power consumed."

"If there are too few defensive magics that can be deployed, there is a great risk of being hit, which requires the magician to have extremely high judgment and precise control. Most magicians I know cannot do this in a short time."

Celia said, pointing her finger, and a magic attack rushed straight to Yakumo's door. But this attack did not work, and was completely blocked by Yakumo's defensive magic - only a hexagon was unfolded.

"See, now you have almost mastered it, and the delay is almost negligible." Celia said, revealing a somewhat regretful expression: "Even Fulilian can't reach this level in one day."

"She is obviously a very talented person, but she always lives a lazy life. If she practices diligently, maybe she can master it in three to five days. So, do you understand how exaggerated your talent is?"

"I won't just take anyone as my disciple." Celia muttered again.

"Of course, besides you, the talent of this Great Kind Tree King cannot be underestimated. Putting aside her actual combat skills, in terms of research, is she really just an ordinary elf? This person seems to be born for knowledge."

"In a sense, she was born for knowledge..." Yakumo's mouth twitched. Celia's intuition was really accurate. The God of Grass was called the God of Wisdom, and could also be considered the God of Knowledge.

"I am not worthy of this. I am still a little ignorant now, and I don't know a lot of knowledge." The Great Compassion Tree King replied modestly: "Compared to Miss Celia, my knowledge is not worth mentioning at the moment."

"In just one month, you've read almost half of the books I have here. Even I can't read as fast as you. What's more, you actually remember all of them?!"

"Ah? Great Compassion Tree King, you didn't use the power of the World Tree here, did you? By the way, can you still use the power of the World Tree now?"

Chapter 18: Power is such an inconvenient thing (31/)

"Hehe, if it's just for recording, it's still okay." The Great Compassion Tree King chuckled: "If it's in Teyvat, according to your understanding, it's like a computer connected to the Internet. I can check and download information at any time."

"But now, leaving Teyvat is like a laptop or tablet without an Internet connection. The only knowledge you can access is what you have stored. Of course, you can continue to input data into it, but you can no longer access it through the Internet."

"It's just that the network is disconnected, but the computer itself is still fully functional. The reason it had some problems before was because it was invaded by a virus. Now that the virus has been removed, it's fully restored."

"Well, that's really convenient..." No wonder I read so fast, I just scanned the whole book and saved it directly on the hard drive, right? I can just pull it out and read it when I need it.

"By the way, where's Aura?" Yakumo suddenly remembered that he hadn't seen his pet for several days since he left it at Celia's place. Could it be that Celia had killed him? He went to check in his backpack first.

"Over there."

Li Ai pointed to the corner next to her, where Aura was sitting in gray.

"This magic of yours is really strange. Aura was indeed controlled because of the backlash of the obedience magic, but the magic controlling Aura now is not the obedience magic. I still can't figure out what it is."

If it weren't for this reason, Celie wouldn't have been so interested in Aura's condition that she wouldn't have objected to the conditions Yakumo proposed before.

After studying for a while, she realized that this was a complete pitfall. She hadn't figured out anything! She even doubted whether what she was studying was magic. How could magic not give any clues like this?!

"How come the method of controlling demons is not magic?" Yakumo argued, "The past is the past, and the present is the present. Who said that magic can't be simplified over time?"

"...Your tone makes me want to hit you." Celie stretched out her hand to hit Yakumo on the head, but found that she was not tall enough, so she had to give up.

"Hey, don't think too much. It's past three o'clock. How about a cup of tea first?" Yakumo also learned how to make tea at Celia. Celia has a lot of good tea. If you don't have the tea-making skills, it would be a waste if you ruin it.
