The Demon Dao cooperated with his Immortal Dao, and this was really the first time I had heard of it.

The relationship between the two sides is not said to be a mortal enemy, it is also what it looks like to fight when they meet, and now when it comes to cooperation, Chen Changan has a hard time believing this guy.

I always think that this guy may have something special in mind.

However, since Youtan has already said this, he really wants to hear what he plans to do.

"What exactly do you want to do? I'm afraid it's not a wise choice to work with me, right? ”

"The relationship between the Immortal Dao and the Demon Dao, I don't need to say much."

Chen Changan said lightly, it seems that this Youtan is also somewhat sure of the whereabouts of the key, otherwise he will not find himself, if he can really take himself to find it, then a small cooperation is fine.

After all, the Immortal Dao and the Demon Dao, who can say clearly about private matters, as long as they are not caught by others, everything will not be too much of a problem.

"I just want to get my hands on a treasure. It's not a big help to you, it's a treasure of our Nine Shadows. ”

Hearing this, Chen Changan was a little stunned, this guy, I'm afraid he knows more.

"Why do you know these things?"

Chen Changan looked at Youtan seriously, it was obvious that what he knew here was something beyond his expectations.

This core secret realm should also be the first time it has appeared, why can he know it in such detail, and besides, this blood arrow also knows something, what these demon paths have mastered.

"I'll show you this, and you'll know."

Youtan said and directly threw Chen Changan a somewhat worn ancient book.

Chen Changan took the letter suspiciously, opened it and looked at it, his face froze, on it, there was a record of this Eternal City Black Tower and the core secret realm.

Although it is not much, it says that there is a treasure of the power of the Nine Shadows here.

And, whether it's the location or the key to open the door, you can match it.

However, this ancient book is also clearly broken, not finished.

"In the secret realm here, I found this ancient book and determined something. And there is also a copy on the Blood Arrow's side, which must be related to the core secret realm here. ”

Youtan didn't hesitate to tell this Chen Changan everything he knew, so that he could understand his sincerity.

"I see."

Chen Changan also suddenly realized, no wonder these demon Dao can find these things, they are originally in the secret realm.

However, it is also strange that the Eternal City is empty.

After all, it was certainly not a city that no one didn't exist at the beginning, but he really hadn't seen anyone. I haven't seen any traces either, so there will definitely be big problems in the past few years.

"But why work with me? A few people on either side of your demon path are not weak, and it is not a good choice to cooperate with me. ”

Chen Changan then asked, looking at this Youtan.

They are not without strong people, and finding a treasure with him will certainly not be too much of a problem.

Therefore, this guy has no reason to find himself, unless he intends to calculate himself because of today's events.

Chen Changan is still very vigilant, and he will not say that he will easily agree to these things.

"Because they don't master the power of thunder, I'm afraid they can only give away people's heads, and it's impossible to do anything."

"So, you are the best choice, not only is your strength enough, but also, if you need anything from this core secret realm, I can also help."

"The exploration ability of our Nine Shadows Clan, but no one can match it, when the time comes, no matter what you want, I can find a way for you."

Listening to Youtan's words, Chen Chang'an was moved, after all, such a cooperation object is indeed very good.

You Tan's ability is also very recognized, and he knows that Yu Tan can detect a lot of things.

After all, the Nine Shadows Clan, no one has left, and they are more suitable for exploring something than a guy like them who has come and gone without a trace.

Today, Youtan has shown himself what he is capable of.

"It's exciting, but how can I trust you?"

Chen Changan looked at Youtan, although he was very moved, but after all, this guy Youtan is a demon, and in the face of this kind of guy, of course Chen Changan can't easily believe it.

Listening to Chen Changan's scruples, Youtan also knew very well that if he wanted to cooperate directly, how could it be so easy, so Youtan also took out a piece of paper that was somewhat ancient.

"This is the order of the contract, as long as the contract is signed, during this time, we will not be able to hurt each other, let alone do anything to each other."

Youtan said directly, he was naturally ready.

"Eternity, is there such a thing?"

Chen Changan immediately asked, he had not been in contact with it, but he was eternally well-informed, and he must have known it.

"Yes, this is a Heavenly Dao contract, once it is established, then it is absolutely impossible to regret it."

"If you regret it, you will be directly punished by the Heavenly Dao, and you will die."

Listening to the eternal words, Chen Changan was also shocked, he never thought that there would be such a thing.

"This is the prototype of the demon pet contract, only more domineering."

"Of course, there are not many of this kind of paper, and the sect that can refine this kind of contract order has long been extinct."

"Besides, there are too many things that need to be done to refine the contract order, and I'm afraid there aren't many people who can collect enough materials right now."

Eternity gave Chen Changan science popularization, this thing can be taken out, he is not surprised, this kind of thing can be described as extremely precious.

However, after all, Youtan is a clan of Nine You, and there is a change in the middle of the Nine Gates of the Immortal Dao.

After all. Developed from antiquity. It's also normal for there to be a change.

But these ancient demon races are different, and it is normal to be able to take out these things.

"You can sign it with confidence, the guy from the Nine Shadows Clan, what he wants to get should be that thing, and it won't be of any use to you."

Listening to the eternal words, Chen Changan nodded slightly, indicating that he agreed.

looked at Chen Changan and agreed. The two also signed the contract directly.

With the contract order taking effect, Chen Changan could clearly feel that there was an inexplicable force that was restraining himself and this Youtan.

There is also a special connection between the two, and if they do something to each other, they will immediately be punished by this kind.

Chen Changan is a little incredible, this contract order can be so powerful?

However, from now on, even if they have reached a cooperation, it is also quite a good thing for Chen Changan.
