Under the watchful eye of the two Millelith soldiers, the two entered the passage.

Yes, the two, Ningguang's secretary is not allowed to enter here either.

Looking at the deep passage from the outside, when you enter, you find that it is a very large space.

Wang Daoyi was even more sure that this was a method similar to the Xianjia Cave Mansion, and it was definitely not a secret base dug up in the mountain cliff.

As soon as I entered the space, I saw several finalists placed on the side, and several young men in white were constantly fiddling.

"In the first battle of Osser, these finalists were once transformed by immortals, and then fell into the sea of clouds, which I commissioned Beidou to salvage, and I am still researching."

Ningguang introduced.

Several young men in white on the side saw Ningguang and raised their hands very enthusiastically to greet them: "Lord Ningguang, welcome to the secret vault." ”

Wang Dao's eyes narrowed, this kind of enthusiastic attitude is not like what Ningguang said.

"How many, long time no see, can there be progress on the new finale?" Ningguang greeted them with a smile.

One of the young men in white looked grateful: "You have provided a lot of materials, which is very helpful for our research, there has been a breakthrough so far, there are many runes that have not been seen in this new finale, as long as you understand these, you can reproduce them." ”

Ning Guang nodded, and then looked at Wang Daoyi, she knew that Wang Daoyi had a connection with immortals, maybe it could help these young people, anyway, if there are dates or not, hit three poles first.

Wang Dao understood what Ningguang meant, but he didn't refuse, and he agreed that researching the new final machine could strengthen Liyue's military strength.

Carefully looking at the final machine that had been soaked in seawater, Wang Dao's eyes glowed with a faint gold.

After an instant, Wang Daoyi retracted his gaze: "It's not an ordinary rune, it's an immortal seal that has been changed by an immortal." ”

The young man in white had a bright eye, looked at Wang Daoyi, and although he looked excited, he still maintained his politeness: "This gentleman, how do you call it?" ”

"Wang Daoyi."

"Mr. Wang Daoyi, you just said that this is an immortal seal, I wonder if you can tell us more?"

I have to say that these young men in white are not at all like what Ningguang said and have a gap with Qixing.

Instead, it looks more like some simple researcher.

For the request of the young man in white, Wang Daoyi did not refuse, stretched out his right hand, and the rock elements converged, forming a rune that was constantly changing slowly: "Most of the runes we usually learn are simple ordinary runes, such as the ones in my hand, whether they are sharp or banned, they are all ordinary runes outlined by the basic inscriptions. ”

Several young men in white looked at the runes in Wang Dao's hand, as researchers in the secret vault, they could completely understand the changes in it.

didn't say anything, and continued to look at Wang Daoyi expectantly.

Wang Daoyi continued to control the runes in his hand, and the originally slowly changing runes showed some 'distortion'.

In the surprised gaze of the young man in white, a 'rune' similar to the one they had just discussed changed.

"And the rune you just studied, that is, the rune that the immortal transformed the finalizer with, is not an ordinary rune, it is a kind of immortal seal, a kind of mutant rune."

After speaking, Wang Daoyi shook his right hand, and the mysterious immortal seal was shattered in his hand, and several young men in white on the side had heartbroken expressions.

"I don't have the textbook of the Immortal Seal in my hand, but you can contact the Demon Slayer families in those ancient points, most of them have records of the Immortal Seal."

After speaking, Wang Daoyi didn't pay attention to the eager gazes of several young people.

He came to find free labor, not to be a teacher, and if he could point in the direction, he was already very generous.

Seeing that Wang Daoyi didn't seem to be ready to continue teaching, Ningguang didn't care, waved his hand and retreated a few young people, and continued to move forward with Wang Daoyi.

As he walked slowly, Ningguang introduced Wang Daoyi to some strange research that he was passing by.

"This is a one-man airship, and it is expected to appear in Liyue next year to make it easier for ordinary people to go out, but of course, it is not allowed inside the city, and can only be used outside the city."

It was a small airship more than four meters high, nearly five or six meters long, and two meters wide, and there was a slightly more mature man in white next to him testing something.

"Oh, food, clothing, shelter and transportation, this airship is very useful." Wang Dao nodded, and then looked at the airship carefully, "Change the material of the airbag, although the slime slime is attributeless, and the gel extracted has a good ability to store elements, but it will also be infected by the elements, and if you use it for two or three years, this airship is a huge wind element bomb, and it is estimated that the hilichurl rocketeer can let a boatload of people go to see the emperor with one arrow." ”

Wang Daoyi's words made the eyes of the white-clothed man on the side of the test data change, but he didn't refute it, but thought about it carefully, and nodded gratefully to Wang Dao.

Although he was still not sure if what Wang Daoyi said was true, he recalled that although slime slime had no attribute properties, it was indeed very easy to be infected by the elements for the second time.

With a smile, Ningguang continued to walk forward with the royal road.

"This is the Elemental Shield Generator, which is said to have become popular among the Knights of Favonius on the Mondstadt side, and I once wrote to the Acting Head of the Order to purchase this technology, but she refused on the grounds that the developer was not in Mondstadt. So, the vault began to study on its own. ”

A very familiar thing, similar to the design of a water gun, with two elemental condensates loaded inside, and a restraint device on the muzzle.

"Huh? This thing," Wang Dao looked at the thing in front of him speechlessly.

Ningguang raised his eyebrows: "What, is there something wrong with this thing?" ”

"Don't you have any intelligence agents in Mondstadt, this is what I proposed, and Mr. Albedo, the master alchemist of Mondstadt, perfected it." Wang Daoyi complained.

"Huh?" Ningguang was also a little surprised, she really didn't receive the corresponding information.

In fact, only Wang Daoyi himself, Albedo, and Captain Qin knew that Wang Daoyi had designed the Elemental Shield Generator, while Xiangling, Ying, Paimon, and Diluc, who participated in the Stormterror crusade, probably also knew something.

It's a pity that these people are not talkative people, and it is impossible for Ningguang's intelligence officers to get any information from them.

As a result, Ningguang didn't know that the R&D person she was looking for had always been in Liyue, right under her nose.

The color of surprise flashed away, and Ning Guang regained his smile: "Since you are a research and development person, how about looking at what we have imitated?" ”

"This thing is a simple elemental reaction device, and it has no technical content, and the imitation is very good." Wang Daoyi said casually, he was a little unhappy, feeling that his things had been stolen.

Sensing the change in Wang Daoyi's tone, a smile appeared in Ningguang's eyes: "Then do you want the General Affairs Department to give you a technical licensing fee?" ”

Waving his hand speechlessly, he was just a little upset, but he didn't want this kind of money: "If you want to pay for the licensing of the technology, let's give it to Mr. Albedo of Mondstadt, I just came up with a very simple idea, and he perfected the device." ”

Ending this topic, Wang Daoyi continued to walk forward, and finally saw something that interested him.

An unfinished replica anchor point device.

Walking quickly in front of the device, Wang Daoyi looked at it with interest, attracting the attention of several old people on the side of the device.

"Who are you? How did you come here? An old man asked unceremoniously.

Ningguang stepped forward quickly: "Master, this is Wang Daoyi, who has come to the secret vault to seek cooperation. ”

Wang Daoyi didn't care about the other party's questioning, he originally disturbed the other party, not to mention questioning, this kind of precious research, it is normal to directly ask someone to beat Wang Daoyi out.

"Sorry to bother you, this is an imitation of the leyline anchor, Keqing took me to use it once before, but I didn't expect to see a semi-finished product here." After Wang Daoyi apologized, he sighed.

The old man's face looked a little better, and he could recognize the anchor point, at least he was a little learned, after all, the half-finished imitation was not at all like the anchor point outside.

"Hmph, that's a bit of insight." The old man snorted coldly, and then went directly to continue fiddling with the anchor point, not even responding to Ningguang's words just now.

Wang Daoyi can be regarded as having seen the attitude of the people of the secret vault towards the seven stars.
