However, Ouyang Dai'er obviously didn't care much.

Walked in directly sideways.

Cao Peng hesitated for a moment, and followed him in.

After coming in, Cao Peng found that there were three ghost head gates, but they were all slightly smaller.

As for the location of the Pavilion Elder just now, it was next to Cao Peng and the others, it was an iron box, and Cao Peng could feel the breath of the other party, but this person did not come out.

But he said that the three ghost heads in front of him had three words written on them: heaven, earth, and people.

Cao Peng didn't expect it to be so complicated after coming in.

"Elder Shouge, the book we are looking for is in the Pavilion! please open the door!" Ouyang Dai'er saluted the iron box and said.

Obviously, she knows more than Cao Peng.

Just when Ouyang Dai'er's words fell, the door of the pavilion opened directly without any warning!

It must be some kind of mechanism!

But Cao Peng couldn't feel the mechanism, which was a little strange.

In fact, the metal here, Cao Peng felt a little strange, his divine thoughts could not penetrate.

If this is the case, if the Shadow Sect is hiding people, then Cao Peng is really difficult to find.

Of course, Cao Peng still wanted to find out which of the Living Dead Sect Master the Shadow Sect was so-called, after all, this was the biggest secret of the Shadow Sect.

There is another one, that is, the living dead of the Corpse Sect, this is from the Wu Clan Patriarch!

But since the Wu clan patriarch said it, then there must be someone who is there.

The door to the Pavilion is open!

It's still the way down, and in this library pavilion, there is nothing electrified, that is to say, there is not even a basic lighting here, only an oil lamp hanging on the stone wall, of course, for Cao Peng, such a light is enough.

However, I always feel a little crazy.

When entering the pavilion, Cao Peng deliberately touched the material of this door, but it didn't move at all, that is, it was harder than normal steel.

It seems that there are a lot of secrets in the Shadow Sect.

At the beginning, Cao Peng thought that the underground sect of the Shadow Sect was so big, but he didn't expect that there was really a hole inside, and he could clearly feel that in the tunnel of this Tongxiang Pavilion, although it was made of bricks and stones all around, but behind the bricks and stones, there were all the same as just now, like repairing the steel bars in the house, the purpose must be to reinforce, in fact, Cao Peng felt that if this became some kind of prison, it was estimated that even if he was now, it would be difficult to get out.

After all, I don't know what kind of material this metal is, and my mind can't pass through it, and it's extremely hard.

For almost two minutes, these two minutes, Cao Peng has been hesitating whether to continue walking, if the party locks itself in here now, then things will be a little dangerous.

The so-called gentleman does not stand under the wall, this situation is that it is normal to have such thoughts.

Ouyang Dai'er walked behind Cao Peng, following step by step, and suddenly said, "Brother Peng, are you scared?"

When Ouyang Daier was before, she had handed over to Cao Peng, Mr. Cao, Brother Peng, Mr. Cao, Deputy Master Cao, etc.!

Among them, Brother Peng is the cutest side of Ouyang Daier, but it is also the most terrifying side.

"Hehe, what are you afraid of?"

"You should have tried this metal just now, isn't it amazing?"

I have to say that Ouyang Dai'er is really a very smart person, such a person, if he is in an antagonistic relationship, it is estimated that it will be quite difficult!

"Yes, I tried it, I don't know what material it is?"

"This metal is called Darksteel!"

"What, dark iron? These are?" "Black iron is a legendary metal, as for the smelting method, including today's scientific and technological development, it has not been refined, because this technology has basically been lost.

Moreover, it is recorded in the classics that Xuantie is actually an extraterrestrial meteorite. It is not refined from the iron at all, and Cao Peng is also more inclined to believe this statement.

However, the dark iron is extremely precious, and in the Gaowu era, if there is a blade of the black iron, it can be called the treasure of the town faction.

And there are so many here, if you talk about Xuantie, Cao Peng will definitely not believe it.

"Hehe, of course it's not the legendary kind of dark iron, according to the classics, it is said that when the Shadow Sect was at its most brilliant, he got a dark iron knife, but the kung fu of the Shadow Sect is biased towards the short blade of the hidden weapon, and finally the sect master of the Shadow Sect integrated this dark iron knife into the ordinary fine iron, and finally the fine iron has some of the characteristics of the dark iron, and later built this library pavilion, relatively speaking, this library pavilion is the treasure of the shadow sect!"

Cao Peng gasped, even so, it was a little terrifying.

"And what about the other half?"

"Guess?"

"Okay!"

The other half, Cao Peng guessed that some secret room must have been built, and now Cao Peng can't touch this secret.

"So, are you afraid of being locked up here?" Finally arrived at the pavilion, the space inside was still very large, there were many bookshelves, all of which were wooden, and there were countless books on the shelves with various threads or bamboo slips!

On the top of the bookshelf, there are also categories.

The pavilion mainly includes all kinds of strange things in the world, including the understanding of some exercises and the like!

At this time, Ouyang Daier looked at Cao Peng with interest.

"Hehe, to be honest, I'm scared, but with you, my heart is still relatively steady!" Cao Peng smiled very purely.

"You can confess, okay, don't think about it, let's find what we want, the time to enter the library can't exceed eight hours, our time is still relatively tight!" Ouyang Dai'er said.

Cao Peng nodded.

Not enough, Cao Peng always kept an eye on it, and felt that he would definitely not come to the library again until he found a metal ability that could destroy this fusion of dark iron in the future.

It's a bit dangerous to talk about it.

In fact, Cao Peng has always felt that his cultivation is not bad, at least, no one in the Shadow Sect has a way to take him, but at this moment, Cao Peng feels that any kind of inherited power should definitely not be underestimated.

The classics here should be cleaned by someone often, and they are relatively clean.

And the air inside is also relatively dry, so it's good to save these things.

Ouyang Dai'er chose a piece for Cao Peng, and what is introduced here is the strange kung fu in the rivers and lakes, of course, there are still a lot of books, and the introduction of the earth escape technique or the bone shrinking technique is still to be found slowly.

Of course, in the process of searching, Cao Peng also studied the things recorded in these books, and he really benefited a lot.

Books are the ladder of human progress, and the Shadow Sect is no exception.

A force that can maintain enough time without decay naturally makes sense!

The background of the Shadow Sect is also quite profound.

No wonder the Ghost Shadow Gate will eventually return, if it is said that the current talents of the Shadow Sect are withering, but the inheritance is still there.

I've been looking for it for about three or four hours. I've seen almost this one!

Cao Peng also found some records about the bone shrinking technique and the earth escape technique, but the records were not very detailed, and Ouyang Dai'er also found them.

After that, Cao Peng and Ouyang Daier began to go to other areas to find relevant records, in fact, the two of them were like sponges absorbing water, looking at these strange stories on the rivers and lakes!

Eight hours, before you know it, it's here.

To be honest, I ate a little casually in the morning, and now Cao Peng is a little hungry, but Ouyang Dai'er doesn't seem to have anything to do, doesn't this woman eat at all?

"Okay, it's almost, let's go out!" Ouyang Dai'er said.

Cao Peng nodded.

When I came out, it was quite smooth, just leave directly, of course, two people are not allowed to bring any classics out, this is the rule.

Coming back from the Library, Cao Peng breathed a long sigh of relief, feeling like he was reincarnated, to be honest, when he was in the Library Pavilion, Cao Peng really felt a strong pressure.

At this time, it was already more than five o'clock in the afternoon.

Cao Peng and Ouyang Dai'er arrived at He Yan's office, and they met with He Yan and talked about what they understood, and then Cao Peng left.

It's really a bit of an adventure today.

Cao Peng felt that this kind of thing could not happen casually in the future.

After all, I still have a lot of missions, and I still have a lot of worries, if I trap myself in a library, even if no one kills me, I will starve to death, and in that environment, if I can't keep it, I will really go crazy.

After returning to the villa, Cao Peng thought that he still had some fears.

In the end, he called Zhao Xingsu directly.

As long as Zhao Xingsu is in the Shen family, he can get through at any time on the phone, this old guy, in the Shen family, basically plays with his mobile phone all day long.

"How's the little demon grandma?"

"I'm about to give birth, what's wrong with you?"

"Damn, I don't have anything to do, can't I give you a call to say hello?"

"It's been so long, you haven't called, do you know that labor and management are boring for a day?" Zhao Xingsu also said angrily.

"Alright, get down to business!"

After Cao Peng told all about today's experience, Zhao Xingsu was silent for a while.

"You must not go to a place like this in the future!"

"Well, I know, but I'm in the Shadow Sect, and it's inevitable that I will enter this kind of place without knowing it, is there any way to destroy this thing?"

Zhao Xingsu thought for a while: "After all, it's not a real Xuantie, so naturally there is a way!"

"What's the solution?"

"Of course it's a cut, or you can bite it!"

Cao Peng was speechless for a while, isn't this nonsense?

But after all, there are requests for people, and at this time, you still can't say this.

"In the past, there were at least five kinds of blades that could be easily cut through this kind of metal mixed with dark iron, but now, there are relatively few!"

"Let's talk about it quickly, otherwise I will have a psychological shadow when I go to the head sect of the Shadow Sect. ”

"Looks like I'm going to reveal a secret to you, and it's up to you what you want to do then. ”

"What's the secret?"

"This secret is your Baili family, it is said that the Baili family has a broken gold dagger, which is made of dark iron, if it is a real black iron, it is naturally very simple to cut this kind of imported product!"

"Nonsense, I also know the broken gold, the life of the patriarch, you still say something else I don't know!"

"There is also a dustless sword in the Huyan family, which can also be ,..."

"Could you please be more practical?"

"The one of the hundred miles is the most practical!"

"I said it all, it is the lifeblood of the patriarch Baili Tianxing, how can it be given to me?" Cao Peng was speechless for a while.

"Hehe, how do you know if you haven't tried it? I suggest that you call your father and ask for this handful of broken gold directly!" Zhao Xingsu said in that tone again, everything was the same as he expected.

"Really?"

"Why don't you try it?"

I haven't been talking to Zhao Xingsu for a long time, Cao Peng began to quarrel with Zhao Xingsu, and Zhao Xingsu hung up the phone angrily in the end.

Cao Peng is satisfied!
