I'm in the Teyvat running group

Yunxiu looked at it and saw that they were two points on the map of Layered Rock Abyss and Sinking Jade Valley.

Seeing Yunxiu's puzzled look, Alice explained, "Below the Abyss of Laminaria lies Liyue's Blackrock Fortress. Information about an ancient kingdom, the 'Langxuan,' is contained there. Of course, you can't enter now, but you can collect some artifacts from Langxuan's gates. These will be needed later."

Langxuan... If I'm not mistaken, this should be the kingdom that the angels guided back then, a city like Lemuria, Yuanxia Palace, and Haipopolia. Of course, I know that its code name in the Golden City civilization is "Eleusius," which is the pure land and city of light in mythology.

Unable to enter now? Yunxiu didn't think too much about it. It was probably because Langxuan was almost destroyed, and there would definitely be other ways to enter in the future.

It seems that the top floor of Langxuan is the bottom floor of the Black Rock Factory... which is where I will be going.

"The reason we can't enter isn't what you think. It's because the crucial moment hasn't arrived yet. The angel from 'Langxuan' hasn't returned, so no one can guide us, not even the Witch's Guild." Seemingly noticing Yunxiu's thoughts, Alice continued, "You should have seen that angel once, but that wasn't her true form, only an avatar, like a celestial being."

The angel of "Langxuan" is most likely Zibai... Yunxiu nodded. Indeed, she had only seen her once. If it was an incarnation, it would explain why she had never appeared in Liyue.

After all, from any perspective, she had no grudge against the Emperor; they might even be friends.

They must have had a pretty good relationship, otherwise how could he have joined one of the Eight Wonders and become the Golden-Eyed Horse Riding the Yellow Moon Steed?

"Since we can't get in... what do you need me to do?" Yunxiu asked, quite puzzled. "If it's Black Rock Factory, then finding a few people should be enough."

“Because there aren’t many people who possess both sufficient strength and versatile methods, and Liyue only has two or three, they’ve already begun preparing to head to Nata; they also have important matters to attend to.” Alice tapped Yunxiu’s head and said, “Besides, finding more won’t hurt you! Remember, at least find one piece of ‘Langxuan Crystal’.”

"Of course, if you can find more, this thing won't do you any harm either."

After saying that, Alice pointed to another spot and said, "You need to find some 'Langpo Ancient Jade' in Chenyu Valley. As for where to find it, you can ask Fujin or Lingyuan directly. This thing should be hard to find, but you should at least have one. Both of these are powerful energy crystals. After I get them, I might be able to try to repair the borders of Teyvat... so that Keperos can spare enough time."

After speaking, she took out a notebook and handed it to Yunxiu. It was filled with dense notes on the characteristics of the minerals and some precautions, but Yunxiu could tell at a glance that many of these precautions were related to radiation protection...

Could this be a Teyvat version of uranium-235...?

Could it be that Teyvat's illusory heavens are powered by a nuclear reactor? If so, wouldn't it be able to explode like a nuclear bomb? That really fits Alice's style.

Seeing Yunxiu's rather strange smile, Alice wasn't angry. She had actually been to Earth, so she could guess what Yunxiu was thinking. She shrugged helplessly and said, "As you can see, this is that thing. So there aren't many that can actually be collected. If you have the ability, you can get some too. I believe you can control it well."

"If it really is one of those 'super bombs,' could you give me two of them after you make them?" Yunxiu asked with a malicious smile.

Chapter 307 The Account Book is Blank, Yet It Represents the Heart Sutra (Second Update on Thursday!)

"What 'super bomb'? It's possible to make that, but that's not what I came here for." Alice's bad habit was that she would start shaking her leg when she lied, and Klee quickly noticed.

"Mom, didn't you say you wanted to get more and teach Klee to make big bombs? The kind that can blow up the whole Cider Lake..." Klee shouted excitedly, "Tell Brother Yunxiu to find more, Klee wants to make a few more big bombs!"

Seeing Alice's increasingly embarrassed expression, Yunxiu couldn't help but laugh, but she didn't say anything. After all, as the Great Witch codenamed A in the Witch Guild, Alice still had to save face. Moreover, public matters should be kept separate from private matters. Yunxiu believed that this witch probably didn't have any bad intentions, but taking the opportunity to get something fun for herself was also her usual style.

Seeing Yunxiu remain silent with a smile on her face, Alice finally couldn't help but speak up: "Okay... I just wanted to get myself something fun! So I asked for about 10% more... Okay, okay, here you go, consider it payment."

What Alice handed over were two bottles of soda that she had somehow kept very secure!

Although she knew that Alice had been to Earth, the appearance of this thing still surprised Yunxiu greatly. After all, finding and storing this thing across worlds is troublesome. This is probably the only remaining stock in this world. Her best solution should be to... find the Academy of Sciences in Fontainebleau to replicate it. They had always been a little short of replicating Happy Water before, but this time they should be able to do it almost perfectly.

Yunxiu casually snapped her fingers, put the soda into her storage bag, and smiled, "This is certainly enough. I'll find more for Aunt Alice later."

"Sigh, these are some of my rare stashes. If you really manage to replicate them successfully, you'll have to give me some too." Alice stood up and patted Klee's head, saying, "Come on, Klee, let's play a little longer today before Mommy goes back to work!"

Klee slung her little backpack over her shoulder and obediently said goodbye to Yunxiu. To be honest, compared to the problem kids in Mondstadt, Klee was indeed a very well-behaved child. As for frying a few fish, it wasn't a big deal. Look at the other unruly kids in Mondstadt, some fighting demons, some messing around with the Fatui, and some even participating in the Northland intelligence organization—what was Klee compared to them?

After greeting Xiangling, Yunxiu made a rare trip to her own business association. Yanfei happened to be working there today, seemingly dealing with some messy financial matters. She wasn't surprised to see Yunxiu arrive, but she smiled mischievously and said, "I heard that our great hero Yunxiu has won over another girl. Now you're thinking about your business?"

"Um... where did you get this information from?" Although this half-immortal had been working for Yunxiu, her strength had improved by leaps and bounds. Yunxiu observed that she had almost stepped into the eighth ring level. Although she was not good at combat, she had four colorful destiny seats and had a good chance of reaching the peak of the legendary realm in the future.

"Xiangling and I are junior sisters, you know. What don't I know?" Yan Fei pushed up her decorative glasses, put down the documents, and asked with a smile, "What brings you here this time? I don't think you'd come here asking pointless questions like how much money you have or how your business is doing lately, would you?"

"Here's the thing, send this to Fontainebleau and let them study it and improve the current Happy Water... then release it quickly." Yunxiu took out the two bottles of Happy Water and handed them to Yanfei. The seal was not difficult to break; a person with the strength of a Primal God could do it easily. After all, it was just about preserving food, and it didn't require any complicated magic.

"Is it really necessary for you to come all this way for such a small matter?" Yan Fei took the bottle of soda, examined it carefully, and found nothing strange. She clapped her hands, and a female secretary walked in. Yan Fei casually gave her a few instructions and then told her to take the bottle of soda away.

"Alright, it should be delivered to Fontaine soon. As for whether it will be successful... it should be fine. They've recently developed many new flavors, which is one of our chamber of commerce's current money-making projects. It's a pity that we have to give Navia a large sum of money. What a shame." Yan Fei sighed, but soon she casually lay down on the large chair and started spinning around, her two feet propped up on the table, white and tender like two bamboo shoots.

"That's really quite unladylike, and doing that in the office every day, aren't you afraid you'll never get married?" Yunxiu sat down next to the desk and smiled. "Or have you completely given up on it? Speaking of which, even a half-immortal like you shouldn't be single, right?"

"Who cares? By the way, do you know what's going on outside? Anyway, the only people in the Chamber of Commerce who have shares are your woman and me. Do you think outsiders will believe that I'm still innocent?" Yan Fei stepped on Yun Xiu's shoulder and said with a hint of amusement, "Of course, this has saved me a lot of trouble. You are a hero of Liyue, the Emperor's son of God. Even Granny Ping and my parents haven't been urging me to do anything."

The atmosphere in the air instantly became ambiguous. Yunxiu knew what Yanfei meant, and he was already mentally prepared. Yanfei had already tacitly approved of his actions by not objecting to the acquisition of shares and continuing to work for him.

The Chamber of Commerce president's office naturally has everything... including a lounge.

What will happen in the break room today is not for outsiders to know (I would like to say, but it is obviously not possible...).

-----------------

Although Yunxiu stayed in the office for three hours, no one was surprised when she came out...

To be honest, Yunxiu also really liked Yanfei. In his previous life, when playing games, he always used Yanfei to get through the early stages. As someone who didn't pull any of the main characters in the early game, he could only use Yanfei to fight his way through until Ayaka Kamisato and Yomiya were released before he put Yanfei into his backup team.

The content of clearing out the entire Yuanxia Palace version is truly impressive!

Of course, he and Yan Fei didn't have much interaction at first. After all, apart from occasionally coming to Wanmintang for a meal, the two didn't really have much interaction, especially in their daily lives. Moreover, Yan Fei was actually not that young.

Although she looks like a young girl, her long life species makes her development period extremely long, and it should take another two or three hundred years before she enters the adult stage... Of course, Yunxiu can make her a magic artifact called the Kiss of Time to fix her age.

The first real interaction I had in my life was when I first made storage bags. At that time, I asked Yanfei to help me with some legal matters. But later, as Yunxiu's business grew bigger and bigger, I simply handed over a lot of things to Yanfei and asked her to build up the various teams in the company.

At first, they would just give her a portion of the shares, but later Yunxiu simply let her fill in whatever she wanted, because these things weren't really important to him.

Even today, a large portion of the money is used for various charitable and construction projects. Yanfei herself has also invested most of her income in the expansion of Liyue and in education and legal education.

For these immortals who call Liyue home, Liyue's strength is simply adding bricks and tiles to their home, so Mora is truly an external thing.

Yan Fei didn't reject the relationship, which meant she wasn't against it. The two of them were just waiting for one of them to make the first move.

In particular, Yan Fei had personally witnessed Yun Xiu rise from a mortal to become an immortal even more powerful than Granny Ping, stirring up trouble throughout Teyvat and even extending the tentacles of the merchant guild to every corner of the Teyvat continent in a short period of time. All sorts of spells, systems, and products emerged in his hands.

In fact, he had already tacitly accepted his future.

As for Granny Ping, she was naturally happy to see it happen. She was a true confidante of the Emperor and knew about these things.

Returning home, I was surprised to see my father and sister resting and cooking. My work in Liyue has been much easier lately, thanks to the existence of the Spirit Realm and the formation of a law enforcement team with truly powerful cultivators. The pressure on public security in Liyue has been reduced considerably.

Especially with the restrictions imposed by the Sealed Spirit Cave Mirror, the spells within Liyue Harbor are limited to the fourth ring, but the law enforcement teams can unleash power of the sixth ring or higher, making it much easier to control the situation.

With the superhumans under control, the governance of nature itself has become easier. The gradual implementation of the new system has also reduced the pressure on the Seven Stars. Even Tian Shu has been able to go home more often lately, which is a rare occurrence.

"Dad, how have you been lately? Li Yue should be able to have a good New Year this year, right?" Yunxiu asked with a smile. "Or are you planning to retire and hand over the Seven Stars position to someone else?"

"This year is indeed quite good, much better than last year. Last year, the Emperor's retirement caused quite a stir, but this year there's not so much trouble, and things are much easier." Tian Shu laughed twice before continuing, "Preparations for the Lantern Festival have also begun this year. How about you? Are you going to bring all the girls you know over to celebrate together?"

"Um...it's not impossible, but I have a few things to take care of. After that, I'll be going to Nata after the New Year. This matter is also closely related to Liyue." Yunxiu helplessly scratched her head. It seems her father wants to see just how many people she's hooked up with this year...

Although Xiangling had been keeping things stable, Yunxiu wasn't really sure if things would get out of hand. But her father had already spoken...

Chapter 308 The Silver Chopsticks Stop Drinking and Questioning the Couple (Third Update on Thursday!)

Seeing Yunxiu's expression, Tian Shu asked in surprise, "Is there something so difficult to solve? Is there something you can't tell my father?"

"He's probably just afraid there are too many of them, and a fight might break out." Huixin walked over and looked at Yunxiu's embarrassed expression, laughing, "My good brother of mine is always attracting women everywhere. According to the records in our Yujingtai archives, there are at least seven registered women, and there should be three or five more unregistered ones... It's said that the new god of Fengdan also has some connection with her, isn't that right?"

"Furina and I are still innocent..."

"Now it is, but will it still be in the future? I've heard that you played a significant role in Lady Funina's ascension to godhood." Huixin rested her chin on her hand, looking at Yunxiu, and said as if joking, "The general of Inazuma, the young lady of the underworld of Fontaine, the great shaman of the Lord of Smoke Mystery, the immortal of Jueyun... Recently, it's said that the head of the Hall of Rebirth has also been seen with you frequently. As a great mage, it seems that my brother really doesn't care much about distance."

"I think I'm innocent with Cetalli for now..." Yunxiu said this with considerable confidence, because nothing had really happened between him and Cetalli. Of course, with Funina, things had indeed reached the final stage, and he didn't have the confidence to continue.

"Really? Then what's going on?"

Huixin handed Yunxiu a comic book. When Yunxiu opened it, it turned out to be a book called "The Overbearing Mage." Inside, it described in detail how she had an encounter with the Nata Smoke Lord, the Great Shaman Sylvanas. It even thoughtfully included the Smoke Lord's tribe name, "Mictaran," and a series of background stories. The content was quite detailed and the research was very solid. In addition, the story of Yunxiu rescuing Sylvanas in Fontainebleau and then participating in the Nata Games to steal a bride was full of ups and downs.

When was this book published?

Yunxiu thought about it carefully and finally remembered when this happened. It was when Minghai Qixia Zhenjun was resurrected, and her grandmother asked her to help design a character for her!

I directly handed the matter over to Ayaka Kamisato, who most likely then passed it on to one of the illustrators and editors at Yaedo, obtaining authorization from both of them. Naturally, these people did whatever they wanted, resulting in this sports-themed romance manga. But that's completely untrue!

"I don't think I did that, did I? I only agreed to design a character for her." Yunxiu handed the book back to Huixin helplessly, and couldn't help but complain, "By the way, where did you get these things from?"

“But that high shaman didn’t object. There’s even her signature on this page.” Huixin pointed to Cecilia’s signature on the title page and laughed, “I think this high shaman has been in love with my good brother for a long time. Did she come here with the intention of secretly pursuing him from the beginning?”

Tian Shu stroked his beard, not particularly surprised. After learning at the gathering at Mount Aozang that Yun Xiu had hooked up with quite a few girls, he had been keeping an eye on this kind of information. Li Yue itself had immortals, and Yu Jing Tai was capable of commanding several legendary powerhouses, so gathering information was naturally not difficult.

So he actually knew more than his daughter, Huixin, but he didn't say much. Teyvat was just that kind of world.

As long as Yunxiu can handle such complicated relationships without affecting his cultivation, he naturally doesn't care too much. Besides, most of the time, what Yunxiu does is something that many girls really can't repay...

Just like resolving Shen He's Lonely Star Calamity, protecting Fu Ning Na's ascension to godhood, and causing the combined rank of the four divine artifacts of Yue Ji to skyrocket, even giving the divine artifact to Hu Tao is nothing compared to that. Not to mention that Sha Tang and Shen Li Ling Hua were actually saved by Yun Xiu. Strictly speaking, only Xiao Gong can be considered a character that Yun Xiu really wants to pursue...

"Let's bring them all over for Dad to see. Bring them all back for this year's Lantern Festival." Tian Shu patted Yun Xiu's shoulder and laughed happily, "In my generation, there are only you and your sister. It seems there will be many in the next generation."

"My dear little brother, now you know what a headache is, right?" Huixin touched Yunxiu's face and smiled. "Eat first. Now, you still have a month to slowly deal with it, don't you?"

I'd be lucky if I could finish the work Alice gave me this month...

Especially these past two days, I've hooked up with Yanfei again, bringing the total to well over ten. Luckily, nothing's happened between me and Grandma yet. But whether or not to bring Fufu over is still a question. Speaking of which, gods just can't unleash their power in other countries, but nobody cares about their travels...

Forget it, now is not the time to think about these things. Let's prepare for Black Rock Factory and Langxuan first. Shenyu Valley is easier to handle; we can just find Fujin when the time comes.

Reluctantly, she ascended to the Spirit Realm and used her privileges to download a large amount of data from Liyue's core database. She then materialized this data directly into reality and brought it to her room. Yunxiu began to organize the Blackrock Depths data bit by bit.

Blackrock Reef actually developed by utilizing the resources of the Laminariat. As for whether it actually used the technology of "Langxuan", Yunxiu believes that it did not, but some technology should have been passed down and applied. This technology is the foundation of Blackrock Reef, and a large amount of equipment in Liyue is now made here.

As for "Langxuan Crystal", there are records. It is located in the waste area at the bottom of the Black Rock Factory. Below this is the original territory of Langxuan. According to the records, this place is indeed shrouded in a strange energy. If the miners and workers who go in do not take proper precautions, they will encounter extremely tragic accidents, which even caused a lot of casualties at the beginning.

According to records, it resembles damage caused by high concentrations of elemental forces, but it also has some unique features, namely, the presence of peculiar, radiation-like energy. This energy can even affect steel, 'corroding' it into strange shapes and creating terrifying cracks.

Only spatial arrays and elemental arrays can effectively block it, but distance is still required, which is why the Black Rock Factory was actually built quite high.

Of course, in their tests, this crystal was actually very stable. Neither the power of the abyss nor the elemental forces could have much of an impact, so over time no one went there anymore.

This aligns well with Yunxiu's understanding of uranium. Many people believe that unless it's a violent nuclear reaction, nuclear explosions, due to high temperature and pressure, would affect various buildings and steel structures. In the case of a nuclear reactor, radiation is easily blocked... This is actually incorrect. Radiation can be extremely damaging to various materials.

Neutron irradiation and its elemental reactions, combined with thermal stress, can cause significant damage to a wide variety of materials.

In the environment of nuclear fission, this is already an extremely terrifying and difficult problem to solve. Of course, it can still be barely solved by slowing down and shielding. However, in the stage of nuclear fusion, because the energy is a level higher, nuclear fusion has not been able to solve the problem of first-wall radiation to this day.

Nuclear fusion is naturally still a long way off.

The more realistic solution now is... to use liquid lithium for the first wall material, which would make it easier to replace some parts, but Yunxiu thinks this is actually quite outrageous.

In Teyvat, this problem is relatively easy to solve because Teyvat has arrays and elemental power. However, precisely because it is relatively easy to solve and energy acquisition is not so troublesome, Teyvat has not actually considered nuclear reactions.

Of course, Canria may have tried, but with the existence of products like the Perpetual Core, the energy output far exceeded the needs of most people, so these things were not further developed.

As for what the Witches' Guild would do with this, Yunxiu guessed that the False Heaven might actually need this thing for its energy supply.

First, Alice would never lie to herself. Second, apart from the False Heaven, there's no need to use such terrifying energy anywhere else. The closest thing might be the Dragon Clan's world-destroying device, Viclopochtli, which can turn Teyvat into cosmic dust.

While the False Heavens may not possess such immense energy, the continuous energy output required to protect the entirety of Teyvat from harm is not insignificant, and may even be greater. As for how they utilize these things, I can learn from them.
