There was silence in the conference room, and after listening to Ye Chen's report, the Human Emperor turned to several aura researchers.

The conspiracy of thousands of years is still continuing, and according to Ye Chen's report, this technology is nearing completion, if it is really completed, I am afraid that the vast majority of the primordial spirit people will disappear, and then the ninjas will reach the top of the world.

"According to this, it may be possible, but according to the technology we have now, at most we can create a simulated environment filled with black aura in a room, and it is not easy to change the whole world, which is equivalent to the yield comparison of a grenade and a nuclear weapon explosion."

The research professors whispered for a moment before speaking.

Although they are also studying the components of the aura, and they also understand the existence of the black aura, they generally directly list it as exhaust gas, just like the rare ingredients that exist in addition to the main nitrogen and oxygen in the air.

"Please prepare a room like this as a laboratory immediately, and I hope to see for myself whether ninjutsu can still work under these conditions."

The Emperor's words made several research professors immediately rush to the laboratory, and only then did the Emperor turn his head to look at Ye Chen.

"Since you can get Crane Blood to speak, I wonder how you're going to make sure she doesn't defect next?"

The Human Emperor squinted his eyes, knowing that this kid must be hiding something behind his back, but as long as he is still loyal, there is no problem with proper concealment, after all, if it weren't for him this time, he wouldn't have been able to know anything about the Co-Prosperity Plan at all.

"Signing a master-servant contract, I believe this should guarantee that she won't betray, right?"

Ye Chen naturally has his plans, for Crane Blood, he will not trust as much as Qian Liuyue, after all, Qian Liuyue took the initiative to leave the family, gave up the war, and gave up the so-called family glory, and the political views are also the opposite of Crane Blood.

"You can get her to sign a master-servant contract with you? What the hell are you kid hiding? ”

This contract is a contract that every ninja will, but for every ninja it is a condition that they are unwilling to accept.

After all, once signed, a slave or a slave will ruin his life, which is impossible for them to accept.

"Don't worry, some things will be known in the future, if my guess is correct, I'm afraid you just plan to let Crane Blood demonstrate it, right?"

Ye Chen smiled slightly, isn't the room where people prepare the black aura just to demonstrate it to everyone, to determine whether they can still use the Yuan Spirit and Ninjutsu in such a state, after all, this black aura is waste gas and cannot be used.

"That's right, if it's really as she said, you'll be considered a great achievement this time, but you kid don't forget your identity."

The Human Emperor is indeed as Ye Chen said, and he also wants to see if it is really as the crane blood said.

"No problem!"

Ye Chen nodded in agreement, and turned back to the underground prison again, still in that room, and saw the crane blood.

This time, Crane Blood calmed down a lot, and when she sat down, she looked at Ye Chen and didn't speak first.

"I've agreed with Dragon's Tooth to give you back your freedom, but there is one condition, in order to prevent you from lying and defecting, I need some guarantees."

Ye Chen said to Crane Blood, but before he finished speaking, Crane Blood had already laughed.

"Isn't it a master-servant contract, I promise you, but I also hope you understand the prohibition in my body, as long as you don't touch the information about the co-prosperity plan, you won't let me die, and it won't hurt you."

Crane Blood stroked her hair, she had already thought of it, after all, the master-servant contract was the safest guarantee.

"I won't read your memory, don't worry, as long as you don't do anything to hurt me, you're absolutely free and safe."

Ye Chen didn't even read the information about Qian Liuyue, let alone touch the so-called prohibition.

"My sister is right, you really look like a gentleman, so this time I believe you!"

The thought flickered, and a multicolored mark shot out from the brow of the crane blood, because the contract used the power of the soul, and did not need the support of spiritual energy, after it was submerged in Ye Chen's eyebrows, the master-servant contract was signed like this.

"I'm not sure if I'm a gentleman, but I'm definitely not careful, so I'm going to ask you to demonstrate the use of black aura."

Accepted the contract, then from this moment on, with only one thought, Crane Blood would die violently, with such a guarantee, she could be regarded as regaining the freedom of her body, so Ye Chen left the basement with Crane Blood and came directly to the laboratory in the Dragon Tooth Base.

Liu Mengfan stood in the corridor, looked at Ye Chen, and then looked at the crane blood behind him, with a trace of strangeness in his eyes but did not speak.

"How's the preparation going?"

Ye Chen didn't notice the change in Liu Mengfan's eyes, he looked at the room inside curiously, the heavy glass windows had been specially processed.

"It's going to take a little time, do you have any questions on your side?"

Liu Mengfan shook his head, it is not an easy thing to extract and maintain the purity of the black aura, and it was originally to separate impurities, this time it was necessary to refine the impurities, although the process is not complicated, but it takes time, after all, the proportion of black aura in the aura is very small, it is really hard to imagine that this co-prosperity plan is actually like this.

"No problem."

Ye Chen walked into the operation room on the side curiously, he was still a little curious about these things, after all, as a person who uses aura to fight, he doesn't pay special attention to the composition of aura, it's like everyone is breathing air, but a few people will care about the various classifications in the air.

"Are you jealous?"

Crane Blood walked to Liu Mengfan's side and said to her with a smile.

"Are you crazy? I don't have the leisure you have. ”

Liu Mengfan didn't look at Hexue, and the previous antagonistic state made her afraid that she would not be able to turn enemies into friends for a while.

"Don't deceive yourself, don't deceive others, the look in your eyes just now has betrayed you, it seems that Wang Yanan is right, you really love my master very much."

Crane Blood smiled lightly and said with a thousand styles.

"You know very well that it's just a ploy, if it's not like this, how can you be caught, your master is not a heartthrob, Miss Ben doesn't look down on it."

Liu Mengfan, who was called by the owner, was even more disgusted, especially the charming appearance of Crane Blood, which she despised even more.

"Duplicity seems to be a woman's biggest obstacle, face your heart, what's the use of escaping, but I have to say, according to my understanding, there are a lot of pink beauties around Ye Chen, and even my unemotional sister has a good impression of him, if you don't take the initiative, I'm afraid the ranking will be thrown far away."

Crane blood's words made Liu Mengfan give her a roll of her eyes, and looked at the curious Ye Chen in the room without speaking.
