There was silence in the dark passageway.

If he was scared because of such a scene, then he wouldn't be called Yechen. On the contrary, seeing the condition of the person of the Ontology Sect, he became even more curious about what was inside.

Anyway, this time Yechen wants to find out.

"It should be safe here, why don't you go back first, and go out directly after the big move outside is over, and you shouldn't be discovered." Yechen pondered for a moment, but decided to persuade again.

Even if he knew the girl in front of him, it was impossible to be at his mercy.

Yue shook her head, but this time the answer was somewhat humane: "Let's go in together, if two people are there, they can still take care of each other." ”

Yechen was a little surprised, before, the girl in front of him had always shown a temperament that was not close to anyone, but now he suddenly came to such a sentence, which made him a little uncomfortable.

But what else can he say, he understands Yue's strength, and he doesn't have to worry about the other party's safety at all.

After making up their minds, the two continued to go deeper quickly, and after twenty minutes passed, the end of the passage finally became different from before.

Yechen stood at the end and looked out, and it seemed to be a plaza similar to a transit station.

Directly in front of them, there was an equally dark passageway, and behind it, or on the wall of the square parallel to Yechen, there were many holes.

Looking at the situation in front of you, it seems that there are many roads here in Mingdu, and there are many secret locations all over the place.

And, if nothing else, at the end of every cave, there is the same Soul Guide Gate.

At this moment, Yechen even began to suspect that the metal door was not an entrance, but an exit.

The design is so tight, and the exit is even more advanced with an unprecedented ninth-level soul guide door, Yechen doesn't know what it is, it is worth Jing Hongchen's trouble.

Without hesitation, the two of them chose to enter the cave in front of them, and after advancing along the passage for another five or six minutes, the environment in front of them suddenly became clear.

This place is different from the outside world, because it is located deep underground in the southwest of Mingde Hall, the soul guide lighting system has not been destroyed, and everything in front of it is clear to Yechen.

It is a huge hall with an area of 500 square meters, and in the center of the hall and near the walls, there are dozens of bookshelves in the village.

The space on the shelves is also huge, with at least nearly 100 books on each shelf, giving it a sense of déjà vu from a library in the previous life.

And on the wall facing the two of them, there is still this rectangular hole.

It seems that there was originally a door here, but it was destroyed from the outside by something with great force.

Yechen no longer hesitated, and came to a nearby bookshelf to flip through it, but this time, the book in his hand could no longer be put down.

Level 9 Soul Guide Design!

That's right, it's the design of the ninth-level soul guide, and every time Mingdetang designs a ninth-level soul guide, the drawing will be made into a book.

This entire book, a total of hundreds of pages, is full of design drawings of various parts and core formations, and even the precautions in the production process are recorded in great detail.

Yechen forcibly suppressed the ecstasy in his heart and continued to check the other books on the shelves, there was no doubt that in the whole summer vacation, about two hundred books, all of them were ninth-level soul guide design drawings without exception!

"Dafa!" Yechen was so calm that he couldn't help but cheer loudly at this moment.

Looking at the other bookshelves, there are from the ninth-level soul guide to the eighth-level soul guide, in addition to the design drawings, there are many other high-level soul guides who have left their experiences, as well as many secret experiment details about Mingde Hall.

Just those soul guide design drawings included all the soul guides that Yechen knew, and the number of ninth-level soul guide design drawings alone was as many as four hundred.

At this point, Yechen is equivalent to directly finding the treasure pavilion of Mingde Hall, similar to the existence of Shrek's library pavilion!

He didn't know if this was all the soul guide data of the Sun and Moon Empire, but it was conservatively estimated that it was more than fifty percent.

So, it's a big deal!

With all this, why did he work so hard to do that unavoidable thing, the task of this trip has been completed!

By now, Yechen finally understood why the Ontology Sect had gone to great lengths to blow up this place, and he didn't know how the old poison got the news.

There is another question that makes Yechen a little puzzled, when he first arrived here, there were traces of being read on the shelves, but for some reason, there was not a single book missing.

And the person from the Ontology Sect left these priceless materials behind and fled in a hurry.

Thinking of this, Yechen looked around, finally locking his gaze to the hole in the other wall.

There is no doubt that the other party has gone in, and the reason for the escape is likely to be related to something inside.

What could it be?

"I have to say, you guys ...... The pace of development is too fast, and these sources are all extremely terrifying weapons. At this moment, Yue suddenly frowned slightly and said.

Listening to the meaning of her words, there seemed to be a skipped in the intermittent place.

Yechen knew the identity of this girl, and naturally knew what he meant: "That's why I will appear here, only when the soul guide department of our academy grows up, can we reduce some of the war for the mainland in the future." ”

After that, Yechen added: "Even avoiding this war is possible." ”

He thought of his plan, everything had been discussed with Xu Tianchen, and the rest was just waiting for the fish to bite the hook.

Looking at the countless materials in the hall, Yechen grinned. Aren't they the best bait?

"Those who see it have a share, so let's wait for me to copy a copy of the contents, and I will hand over the original version to you, what do you think?" Yechen asked, he also wanted to swallow it himself, but in comparison, he was more afraid of turning his face with the girl in this situation.

But what he didn't expect was that the girl categorically refused: "No need, I don't need these things, you better keep them for yourself." ”

Yue's tone was very flat, as if these incomparably precious materials in the eyes of outsiders were worthless to her.

Yechen spread his hands and didn't force it.

Besides, it's been nearly twenty minutes since they've been in the passage, and they'll have to speed up.

Otherwise, when Jing Hongchen finishes dealing with the affairs of the Ontology Sect, once he reacts, the unlucky one will become Yechen.

Thinking of this, Yechen quickly started moving.

He knew that after he went out, as long as Jing Hongchen found that the things here were gone, he would definitely thoroughly check everyone's storage soul guides, and everyone in Shrek Academy was the object of great suspicion.

Therefore, Yechen chooses to put things into a small world, where no one but himself can snoop into the secrets without permission.
