I'm in the Teyvat running group

As for the Black Rock Factory itself, there is no danger. As long as Yunxiu has the certificate issued by the Seven Stars, she can enter the bottom without any obstacles. This is the simplest. She can just ask her father to issue two certificates for her later.

The person most suitable to accompany me on this trip is actually Firefly. Her armor can move freely on a planet with a pressure of millions of atmospheres and witness the explosion of a supernova. This task is almost effortless for her, and if I join forces with her, making a round trip to such a place should be more than enough.

The only problem is whether I can withstand such pressure. But I am a legendary defensive mage. At worst, I can use invincibility. How much of a threat can Blackrock Factory pose to me?

Hearing that her father had called her to dinner, Yunxiu put away all the documents, and the family of four sat down together for a rare meal—Liuying had also returned.

Tian Shu naturally liked Liu Ying very much, especially since Liu Ying even helped Qi Xing deal with many demons. After Yun Xiu solved the entropy disorder, this powerful Grammer Iron Cavalryman's strength was no less than that of the Floating House Immortal.

The two had faced off once, and Fushe was slightly outmatched, mainly because Fushe was not as skilled in aerial combat as Liuying.

Yunxiu was actually very surprised when she heard about this.

Chapter 309 From the Abyss, Filth Gazes at Crystal Light (Third Update on Thursday!)

It's not surprising that Fushe isn't good at aerial combat, because even among legendary powerhouses, there aren't many who excel at aerial fighting, and even among demon gods, they are quite rare.

Even among the seven elemental dragon kings, some are not skilled in aerial combat. Otherwise, why would Dvalin be known as the King of the Sky? Among the legends, Dvalin is actually considered to have relatively weak frontal attack power. He excels in aerial combat and large-scale group attacks. He is a legendary figure who can truly fight against an entire nation's army by himself, and few legends can rival him.

Liu Ying's combat strength is not actually outstanding among the legendary peak, but her background as a member of the Grammer Iron Cavalry and her extensive combat experience have given her a terrifying boost. That is, she has so many fighting styles and methods that she is a legendary powerhouse without any weaknesses, which even surpasses Yun Xiu!

Aerial combat is her forte, especially since the Grammer Knights primarily fight in space, making aerial combat a piece of cake for them.

As for Fushe, although he often bombards enemies head-on, he is actually best at assassinations by traveling long distances. He has a record of assassinating demon gods' followers multiple times during the Demon God War. Of course, none of the Yakshas are actually very good at aerial combat, except for Xiao, who is slightly better.

That's why it got the title "Golden Roc". Of course, according to Grandma Ping, in the aerial battle between Firefly and Xiao, Xiao actually had a slight advantage over Firefly, but in the ground battle, he was caught off guard by Firefly's powerful attacks.

After finishing her meal, Yunxiu first had her father obtain two certificates, and then explained the matter to Liuying. Liuying naturally had no objections and even said quite happily, "I have actually fought in a high-radiation environment before, and now I can do it again."

"By the way, what kind of high-radiation environment did you encounter? Was it a similar situation, or are the environments on different planets different, and the radiation itself varies greatly? Would you encounter any problems?" Since it was rare to meet someone who had actually fought in such environments many times, Yunxiu naturally wanted to ask seriously: "Also... what is the biggest difficulty in this situation?"

“There are only so many fundamental particles in a universe, so naturally the principles of all radiation are not much different.” Liu Ying smiled, then said seriously, “How could there be radiation formed by some inexplicable element? Our Grammer's periodic table only has element number 129, and from element number 122 onwards, three-dimensional space basically cannot sustain the existence of such elements. They will disappear the moment they are created and cannot exist at all.”

"Are the elements in this universe... different from those in that universe?" Yunxiu asked curiously, as he had never really paid attention to these things before.

In the real world, the dividing line for elements is neptunium (number 93), which is the last element to exist in nature, though it is extremely rare. Starting with element 94, elements must be synthesized in laboratories. Uranium, which is used by humans, is actually element 92. This radioactive substance is unstable, which is why it is used to make explosives.

“I’ve observed it; there are differences, but at least up to number 78, there’s no difference. From number 79 onwards, subtle changes appear.” With a flick of her finger, a virtual screen appeared in the air. Pointing to the atomic sequence of number 79, she said, “This element is actually ‘gold’ in our universe, but in this world, a peculiar difference has occurred. Gold has become a catalyst, namely ‘Mora’!”

"But in reality, 'gold' should be a very stable element, which is truly unbelievable. Later, I happened to meet the Emperor and asked him about it, but the Emperor told me that this matter was beyond my reach."

Is that so...?

Yunxiu initially thought that Mora was actually an improvement on the gold element, that is, a product of transformation, but she did not expect that it was directly created by kneading, which directly changed the properties of gold itself. How terrifying!

If that's the case, let alone someone like Firefly, even a certain demon god would probably be unable to reach it. Speaking of which, if that's the case, could Teyvat really be the legendary advanced world? Otherwise, why would it suppress so much power and have such a significant impact on the universe...?

"The Emperor must have his reasons for doing this. Perhaps we will be able to uncover this secret in the future," Yunxiu said with a smile. "Then the elements that follow will be completely different?"

"Yes, there were some differences before number 95, but most of them were not significant. However, things changed starting with number 95. There are some relatively advanced civilizations in this universe, and I have obtained some information about them." After thinking for a moment, Liu Ying said, "Perhaps it's because this universe has a peculiar energy that makes these things different?"

“Then take a look at the information on this ‘Langxuan Crystal’. What is this thing?” Yunxiu handed over a document containing some relevant samples and tests, some of which were brought over by Alice.

Liu Ying took the data, glanced at it briefly, and then said seriously, "This should be element number 94 of this universe. It is indeed an element that naturally carries radiation."

Number 94, I see. This thing actually corresponds to plutonium, which is the first man-made element that humans can produce on a large scale. It is one of the materials for nuclear bombs. Could it be that the demon god of Langxuan can actually use its own nuclear reaction to produce this Langxuan crystal, and then this terrifying product appeared?

If that's the case, then it's not surprising at all that the "Tears of Selenne" belong to Langxuan. Such a kingdom truly needs this purifying artifact; otherwise, whether it can even survive normally is a question...

However, that purification was actually too violent, so even powerful legendary experts needed a certain method to access it, which is perhaps one of the reasons why Langxuan was like this.

If that's the case, could the destruction of Langxuan be because the Demon God wanted to turn himself into a nuclear bomb and explode on Sky Island, or perhaps the people of Langxuan planned to develop a nuclear bomb and shoot down Sky Island in one go?

The destruction of Langxuan is not surprising at all. If it really is plutonium, then judging from the fact that he is going to destroy one side this time, the amount of Langxuan crystals produced by Langxuan back then is probably terrifying, enough to make tens of thousands of crystals.

The energy of a single shot was almost equivalent to that of a legendary spell. This terrifying power, even if it didn't destroy Sky Island, would most likely cause it immense damage. Therefore, this act of recklessness was probably not much different from that of Kanria. For the first time, Yunxiu truly understood Fanes's mentality...

Never mind, I'll go to sleep first...

After discussing the Black Rock Factory operation with Liuying for the next day, the two of them went straight to sleep.

Although Yunxiu wanted to bring up the Lantern Festival again to bring up the idea of ​​bringing all the girls back, she held back because she thought that Liuying might get angry about it tonight.

This girlfriend is incredibly jealous. It was fine when I was already in a relationship with her, but things are about to get out of hand. I need to save my life!

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

The next morning, the two washed up and headed straight for the Black Rock Factory.

Strictly speaking, Blackrock Factory is built inside a mountain, or rather, the entire mountain has been almost hollowed out. However, thanks to Liyue's excellent control, there has been no situation of billowing black smoke.

Because of the presence of many plants, you wouldn't be able to tell from outside the mountain that this is actually a factory... Of course, it is still guarded by the Thousand Rock Army, and Liyue people generally don't come here.

After handing over their passes, the soldiers politely let Yunxiu and Liuying in. Soon, Kun Yue, the steward in charge of the Black Rock Factory's forging operations and a descendant of the Kun family, came to greet them. He glanced at the two of them, seemingly carefully distinguishing them, before smiling at Yunxiu and saying, "I am Kun Yue, the person in charge here. You may address me as whatever you like, Lady Yunxiu... But may I ask what brings you two here today?"

“We’re going to the waste disposal area at the bottom… I don’t think it will affect your work.” Yunxiu naturally wouldn’t make things difficult for them, and said quite seriously, “If there are any difficulties, please feel free to tell us. Of course, if you need any help, please don’t hesitate to ask.”

“It’s not that difficult…” Kun Yue said with a troubled expression, “There is a demon that has been lurking in the waste area recently. If you two cannot deal with it, it will be difficult to get down. Of course, because of the formation, the demon cannot affect us. I originally planned to report to the Seven Stars in the next few days to seek the help of one or two immortals, but I heard that you two are also beings no less than immortals.”

"What kind of monsters could survive in this environment?" Liu Ying asked with great curiosity. "If it's really as I think, even immortals wouldn't last long in here, right?"

“That’s what we think too, because the demon’s strength is clearly not beyond this range, and it poses no threat to the formation set up by the immortals.” Kun Yue thought for a moment before saying uncertainly, “If there is any impact, the only one is that its voice is really unpleasant and has affected some mining operations, but after setting up a soundproof formation, there is no problem.”

It's amazing that Teyvat has such monsters. Even abyssal monsters shouldn't be able to last long under these conditions...

Yunxiu stroked her chin, thought for a moment, and then said, "Then let's go take a look. If we can handle it, of course there's no problem."

"Thank you both so much." Kun Yue was quite pleased and personally led the way. This problem had been a major headache for him recently, and he was only burying his head in the sand. In the end, he would have to report to the Seven Stars. It was rare for an immortal to come, so he had to resolve these matters as soon as possible.

"Let me show you both around Blackrock Factory. It's one of the best places in Liyue."

Chapter 310 The Sound of a Thousand Machines Melting and Forging into the Earth (First Update on Friday!)

What exactly is Black Rock Factory like? If Yunxiu were to evaluate it herself, Black Rock Factory would probably be a city built inside a mountain peak, a real city.

Because if you don't describe it as a city, you can't understand the awe-inspiring nature of this forging factory. Unlike the Mikage Furnace in Inazuma and the mechanical forging in Fontaine, the forging at Blackrock Fortress is a combination of human and machine, and it also incorporates Liyue's unique array and rune system, making it a truly magical system.

According to Kun Yue, forging itself is not actually that complicated; in fact, it is quite simple. The most troublesome part is the formation of the weapon.

So for now, array formations and talismans still have to be done by people, but the processes of weapon blanking, quenching, and forging can be handed over to machines. Even the smelting and shaping of ores are done by machines. Of course, Liyue calls them mechanisms, and many mechanisms are finished products obtained directly from the immortals.

Yunxiu glanced at it and indeed found the mark of a crane on it.

I knew it would be you again...

Yunxiu was already very used to the omnipresence of the True Lord of Clouds and Wind. Her interest lay in developing these things. Although she had recently attracted a lot of attention to Yunxiu's projects, it didn't mean she had stopped working on other projects. She had just been working on fewer of them. On the contrary, the addition of new technologies had made her development capabilities even stronger.

After all, there was no such thing as a spirit realm before, which allowed her to communicate with this group of people throughout Teyvat. Naturally, she didn't have as many ideas and inspirations. Take the "Spirit Frame" in Jade Capital Terrace, for example; it has already been iterated into racing and transportation versions.

The Teyvats' level of wildness in driving racing cars is much higher than Yunxiu imagined, so these things sell quite well. Occasionally, you can even see guys racing on the Yunlai Sea—that's right, these things can be raced on the sea. To ensure the speed of the Lingming Frame, the True Lord Liuyun Jiefeng used a floating formation.

Without using floating stones, the levitation distance is very low, about half the height of a demon's body, but it's just right for speeding across the sea, as many parts of Yunlai Sea are indeed calm.

As for the Blackrock Factory itself, there isn't much to see. Strictly speaking, it's quite similar to the Crimson King's Tomb. The similarities lie in the powerful energy cores, various workshops, and numerous mechanisms that deliver all sorts of resources and materials. Uncut pieces of armor and weapons are transported out through various channels, quenched in cold water, and then engraved with runes.

Finally, the equipment is handed over to individual craftsmen to inscribe the magic array. Most general-purpose equipment has similar magic arrays, but only a few captain-level or higher equipment require a master craftsman to inscribe it personally, and some even require a Genshin Impact-level blacksmith to do it.

As for something even more powerful, you'd generally have to seek out immortals.

However, the Emperor would bestow some divine artifacts every now and then, and the immortals would also release some practice works, so this was not a big problem. Especially for Liu Yun Jie Feng Zhen Jun, more than 30% of the weapons of the Genshin Impact characters in Liyue were made by him. To be honest, in terms of sheer diligence, Yunxiu had never seen anyone more diligent than Liu Yun Jie Feng.

The few who carved the moon and built the sun were rather lazy. The second most diligent one now is the True Lord of the Sea and the Clouds. He is also an inventive fellow, and many magical treasures are his creations.

He even recently optimized the distribution mechanism of the Spirit Realm, making the Spirit Realm itself more powerful—a method that even the immortals hadn't come up with.

The three of them walked through a series of mechanisms in the Black Rock Factory and soon arrived at the shielding array of the bottom waste area. There was a huge isolation room in front of it, and basically no one came here anymore. Waste was mostly transported by mechanisms, and occasionally a few powerful people would look for some resources, that was all.

"Gentlemen, this is the place. I can't just go in like this. The technicians at Black Rock Factory also need very heavy work clothes for repairs." Kun Yue cupped his hands in greeting and continued, "If you two need work clothes, you can change in the shielded room on the right-hand side of the entrance. Don't worry about whether they fit or not; most of these things are adjustable."

“We probably won’t need it, but… we still need to reinforce this place later. It’s obvious that although the protective ability of the magic array here is very strong, it can’t withstand real threats.” Yunxiu touched the magic array and with a wave of his hand, he added an automatic spell counter array. He couldn’t cover too many arrays in a short time, since this kind of reinforcement method might cause problems later.

“You’re right, we’ll report to the Seven Stars right away…” Kun Yue said with a hint of helplessness, “In the past, most people didn’t really pay attention to these things, after all, no one has come here for a long time. If it weren’t for the recent appearance of demons here, perhaps it would have been a long time before anyone paid attention to this place.”

"I was just saying it casually. You guys should figure out how to handle it." Yunxiu smiled and led Liuying into the formation. With his strength, he could enter at will. As for what kind of demons were inside, they would definitely have to go inside to find out.

As soon as I entered the gate, I could feel the damage. It was roughly equivalent to the fourth-ring level of Abyss damage, 1D6 per second, averaging around 800 points. As long as I activated my elemental power, I could withstand it. Most of the repair technicians who entered here were at the fifth-ring level. Moreover, the shielded room was right next to the gate, so I could just wait a second or two to get in.

Yunxiu had also considered why not place the shielded room outside, but she quickly realized that placing it inside was also a form of protection. If a situation arose where it was necessary to lock the entrance and exit, it would be much more convenient for one or two strong individuals to enter the room than to put on their protective gear outside before going in. After all, these things were extremely heavy, similar to how deep-sea diving suits were put on and taken off underwater. Wearing such a suit and being able to walk five meters on land would make one an iron man...

Liu Ying instantly donned the SAM armor, completely ignoring the radiation.

Every ten meters or so, the radiation intensity increased significantly. When you reached the deepest point, the damage to a person reached the level of 4D6 erosion, which is equivalent to a ninth-ring erosion. On average, the radiation loss was 10,000 to 20,000 units per second. However, this was not a major problem for Yunxiu.

He has two million Arcane Protection points per layer, and he can refresh Arcane Protection by casting a Shield spell every one or two minutes, so he can basically move around freely.

"Two layers of shielding arrays... the pressure behind this is definitely beyond imagination." Yunxiu walked to the end of the isolation room in the waste area. This was the second shielding array, with a two-layer structure. Judging from the patterns on the array itself, it seemed to be an array jointly set up by "Shaving the Moon and Building the Sun" and "Managing Water and Stacking Mountains"...

"It's very powerful. The threat level to my armor has reached 4.5%... It's almost at the level of some stars." Liu Ying glanced at her display screen. Her armor was already powerful, and after undergoing a self-sublimation and evolution, it is now almost a powerful existence among god-level weapons.

After making some preparations and replenishing her own strength, Yunxiu cast two spells on Liuying before finally opening the formation here.

In an instant, the damage numbers suddenly increased seven or eight times, catching Yunxiu off guard. His shield, which had a million health points, rapidly dropped to over 100,000, and in less than thirty seconds, it had already broken through two of his shields!

Fortunately, he had a total of thirty-three floors...

"The threat level has risen to 27%, approaching the level of a supernova. What kind of monsters can survive here?" This level of threat is clearly making Firefly uncomfortable. Even the Sam Armor needs to fight carefully in this area. The pressure is not much different from the battlefield against the insect plague in the later stages.

"If we take the final battle against the locust plague as a basis, what level do you think this monster is roughly?" Yunxiu asked seriously. "Ignoring all the messy situations, just talking about the monster's combat strength and level, who do you think is closest to it in terms of combat strength and level?"

Liu Ying had sparred with almost all the immortals in Liyue, and she knew them best. Yun Xiu herself had hardly fought anyone, and the few times they did spar, it was always to a point where no one could defeat the other. After everyone realized that no one could break Yun Xiu's tortoise shell, they gave up.

“I think he’s probably close to the level of Lord Lishui Dieshan… He’s one of the more average-strength masters among the Liyue masters.” Liuying pondered for a moment before continuing, “This is only considering the situation of surviving here. If we consider his attack power, I think it would be a bit higher, but it would still be within our range of dealing with.”

"Alright... looks like we'll have to rid Liyue of another menace. By the way, do you think Aunt Iris already knew there were monsters here when she tricked us into coming here to collect 'Langxuan Crystals'?"

"Who knows?" Liu Ying drew two swords, but her voice didn't become deep. Yun Xiu had asked about this later. In fact, this voice changer could be turned on and off freely, and it could change into other voices. Yun Xiu had once wanted to try it out in a wicked way to see what would happen if she used that voice in certain situations, and then she became even more excited.

By the way, the transformation device isn't actually that useful. The Grammer Knight transformation can be freely activated and deactivated. The reason Firefly uses the transformation device is simply because it looks cool...

The two continued walking forward. The radiation intensity did not increase significantly after entering this area, and scattered pieces of Langxuan crystal began to appear. Yunxiu had Liuying pick up two pieces and did a simple test. Sure enough, they were products similar to plutonium, and they were also element 94 of this world. It was obviously a product of the evolution of the demon god, not a natural one.

The plants that grow in this environment are incredibly terrifying. Even Yunxiu never imagined that Teyvat would have such terrifying plants that could grow in this environment!

Based on the identification results, it was just an ordinary sweet flower—but considering that even the Wild Hunt-ravaged Nordkale had sweet flowers, Yunxiu was able to accept it…

He took out several boxes and used magic to collect some sweet flowers and plant fragments from the area, intending to bring them back to Sugar. He was sure Sugar would like these things. Then Yunxiu led Liuying onward.

After operating in this environment for more than thirty minutes, with their Arcane Protection refreshed more than ten times, the two finally reached the highest point of the energy reaction. The cave below was extremely distorted and terrifying, completely unlike anything that could be seen in Teyvat.

Inside the vast Langxuan Crystal mine, there is a peculiar entrance made up of various stones, crystals, and debris. Beside it grows even more terrifying giant mutated sweet flowers and some unknown plants, making Yunxiu's eyelids twitch. Moreover, these sweet flowers seem to have mutated into life, frantically waving and throwing strange water droplets at Yunxiu!
