Because, Xiao Dream Shadow Butterfly is the best at this, and I believe that with its help, it is not difficult to do it by yourself.

So the question now is, should Fang Yan believe in Zhuxin?

Also, even if Zhu Xin could help Fang Yan conceal the vision of heaven and earth, once Fang Yan stepped out of the other party's cave sky, it would immediately attract a thunder tribulation.

To be honest, Fang Yan had never thought that he would advance at this time, so he was not prepared to deal with the Thunder Tribulation in the slightest.

At the very least, Fang Yan knew that it was definitely not suitable for advancement in the Ascending Dragon Realm.

Although Fang Yan had a lot of treasures in his hands, he didn't dare to say that he would definitely be able to survive the thunder tribulation.

But the Ascending Dragon Realm is a super vast secret realm, maybe after Fang Yan successfully advances, he will not encounter a thunder tribulation when he comes out of it.

Seeing that Fang Yan was silent, Zhu Xin's eyes flickered, and he also knew that this matter was indeed a difficult choice for Fang Yan.

And the reason why Zhu Xin had this proposal and was willing to leak some of his secrets made a huge breakthrough in Fang Yan's state of mind, and he couldn't even suppress it anymore and had to advance immediately, not necessarily because he wanted to let Fang Yan enter his own cave heaven.

It's just that......

Rao is able to see through people's hearts and gain insight into many hidden things, but at this moment, he can't see the decision that Fang Yan will make in the end, and he can't help but feel apprehensive in his heart.

After thinking about it for a long time, Fang Yan had already figured it out. If you have the means to restrain the new ones, you will definitely agree to the other party's request.

But if it is the slightest binding force on Zhuxin, it will not ......

Fang Yan began to think about it, Zhu Xin, as a half-human, half-demon body, would he be bound by the Heavenly Dao?

After a long time, Fang Yan felt that this possibility was not low, after all, even if it was a half-human, there was human blood flowing, and it should be, and it was also subject to some constraints, right?

"Thank you seniors, you seniors have done so many things to invite you to enter your cave, I think you should also show your sincerity, right?"

When Zhu Xin heard Fang Yan say this, he showed a wry smile, it seemed that the other party had already seen through his intentions.

Seeing this, Zhu Xin felt that he had nothing to hide, so he asked rhetorically: "I don't know what kind of sincerity do you want to see Fang Daoyou?"

Fang Yan's eyes flashed slightly, and he secretly guessed to himself, could it be that if he entered the other party's Cave Heaven Advancement, what would he do to the other party?

"Also, seniors, I don't know if after I successfully advanced to the Yuan Infant Stage, I will trigger the Thunder Tribulation to descend the moment I step out of the Ascending Dragon Realm......

Zhu Xin smiled slightly: "No, after all, no matter how vast the Ascending Dragon Realm is, it is only a secret realm." ”

Fang Yan didn't dare to believe it completely, but she also felt that the other party's words were reasonable, which was similar to what she expected.

"Seniors, you might as well make a heavenly oath that you will never hurt you, how about it?"

After being silent for a while, Fang Yan opened his mouth tentatively.

Zhu Xin was stunned, but the expression on his face made Fang Yan unable to see anything, and he immediately nodded in response, and immediately launched the Heavenly Dao Oath.

So simply, could it be that the Heavenly Dao Oath has no restraint on it?

Fang Yan thought like this, his heart tightened, and then he couldn't help but think of the Luo Demon Contract that he learned from Jian Chengqi.

If he has the Luo Demon Contract in hand and lets Zhu Xin sign it, will he be able to restrain him?

"One last thing, I don't know if the seniors can carry the Luo Demon Contract?"

As soon as Fang Yan's words came out, Zhu Xin showed a somewhat self-deprecating smile: "How precious is the Luo Demon Contract, how can a half-demon like me have it?"

That's nothing.

Fang Yan was extremely disappointed in his heart, and at this time, Fang Yan couldn't help but think of something, and with excitement, he probed his divine sense into the storage ring.

Among the storage rings, there is a letter given by Guan Qingtong, which has completely become blank, and in addition, there is also a bag that Guan Qingtong asked Pan Hetong to hand over to him.

When this bag was handed over to Fang Yan, Pan Hetong didn't say much, just said that Fang Yan should put it away in case of emergency, instead of being told to check it as soon as possible like the letter to Fang Yan.

And after Fang Yan mixed into the Heavenly Demons, there were many things, so he didn't think about it anymore.

Now that I think about it, with the character of a god, will there be a Luo Demon Contract that can restrain the Heavenly Demons?

Thinking of this, Fang Yan was overjoyed, so he held the bag in his hand in front of Zhu Xin, and then probed with his senses, and sure enough, he found that there was a blank piece inside, which seemed to be a contract.

Fang Yan unfolded it in surprise, only to find that this was not a Luo Demon contract at all.

Although I have never seen it, I also know that the Luo Demon contract clearly states that the constraints on the Heavenly Demon and many living beings are clearly written.

And on this contract, there is no mention of the Heavenly Demon.

Fang Yan was stunned, but he didn't dare to regard it as a useless thing, so he read it carefully.

Immediately, Fang Yan's eyes lit up, and he couldn't help but admire Guan Qingtong so much that he threw himself to the ground, and then he felt a strong sense of gratitude.

Because of the binding force of this contract, for the son of the heart demon like Zhu Xin, the binding force must still be on top of the Luo Demon contract.

This is a contract specifically for Zhu Xin, a half-demon with the blood of the human race and the blood of the heart demon.

It's called the Human-Demon Contract.

Seeing Fang Yan's changing expression, he was finally frozen in ecstasy, and Zhu Xin suddenly had a bad premonition.

Zhu Xin naturally knew that the Heavenly Dao Oath was indeed somewhat binding on him, but it was very small, and it was not impossible to exorcise it afterwards as the son of the heart demon.

As for the Luo Demon Contract, the binding force is slightly stronger than the Heavenly Dao Oath, but it is far less powerful than the real Demon Clan's strong binding force on Zhuxin.

Even if he violated, the punishment that Zhu Xin received would not be to the point of ten thousand ants devouring his heart, at most it would be a little painful, and it would not last, and it would hardly have a big impact.

And once Zhu Xin chooses to let the Terran bloodline in his body suppress the demon bloodline, and regards himself as a Terran, and no longer uses the power of the Demon Race, then that bit of binding force will disappear with the wind.

Therefore, even if Fang Yan could really change a Luo Demon contract like a Duobao Dao person, Zhu Xin didn't have much to fear.

But looking at Fang Yan's expression now, Zhu Xin felt a little unexpected.

"Fang Daoyou, why are you so happy?"

Zhu Xin immediately released his divine sense, wanting to spy on the contract in Fang Yan's hand, but found that his divine sense could not be detected at all, and his heart sank.

"Isn't it worth being happy to be able to accept the invitation of your predecessors and enter your cave heaven right away?"

Fang Yan smiled, and then said, "Seniors, let's sign a contract!"

Zhu Xin: "......"

In the end, under the struggle, Zhu Xin reluctantly agreed to the contract formulated by Fang Yan, but modified some places.

Zhu Xin found that only if Fang Yan willingly gave the contract to himself to see, he could see the content of the contract, and he couldn't help but be shocked in his heart, and immediately knew that this contract was probably super binding on himself.

"If the human demon violates the contract regulations, the punishment of the Heavenly Dao Oath and the Luo Demon contract will be lowered at the same time......"
