Standing behind Ye Tian is the demon king. And Xiao Zhou is just his man.

In fact, ye Tian had guessed what Xiao Zhou said before. I just didn't expect that the demon king arrived here. Now, his life is in the hands of the demon king. As long as the devil is willing, he can kill him at any time.

However, of course, the devil will not do so. He always thinks highly of Ye Tian. How can he be willing to kill him?

"Ye Tian, there are only two choices in front of you now." The devil said slowly, "first, choose to cooperate with me. Second, before my goal is achieved, you can only rest for a period of time. How to choose, you can make your own decision."

Ye Tian sighed slightly and said, "do I have any choice?"

The devil smiled: "originally I thought you were a man who was not afraid of death. Now it seems that I misunderstood you."

Ye Tian smiled faintly and said, "a hero doesn't suffer immediate losses. Only a fool will do something harmful to himself for the so-called righteousness. If it were you, I'm afraid it would be the same as me."

Hearing the speech, the demon king laughed and said, "yes, that's good. If it were me, I would be the same as you, because we are all the same people."

Ye Tian shrugged and said, "my legs are a little stiff. Now I can always move?"

"Yes, but you have to think about the consequences of chaos." The demon king said faintly. His voice was not high, but it was very frightening.

Ye Tian smiled bitterly: "speaking of it, you still owe me a favor. I thought you would repay me. I didn't expect that you didn't repay me, but it was revenge for kindness."

"No, no, No." The demon king shook his head and said, "Ye Tian, I have always remembered your kindness to save me, and I will repay you naturally, but not now."

"It's just a word from you. I won't take it seriously anymore."

The devil smiled: "I believe you, ye Tian, you'd better not let me down." After talking, he suddenly stepped back.

Ye Tian turned around, moved his stiff waist, looked at the demon king and said, "I really want to know your plan. Why do you involve the whole Jincheng?"

The demon king looked at Ye Tian meaningfully, as if he was hesitating whether to tell him the plan. After all, ye Tian is not sure whether he is an enemy or a friend.

Ye Tian saw his mind, shrugged and smiled and said, "if you feel inconvenient, you don't have to say."

"I can tell you." The demon king said lightly, "it's not because of your aggressive method, but it's OK to tell you." After a pause, he continued, "you should know that my purpose in coming back this time is to uncover the seal, but if I want to uncover the seal, I must make the whole Jincheng chaotic. Only in this way can the alert of F special police relax."

"Does this have anything to do with F special police?" Ye Tian asked somewhat puzzled, "is f special police also looking for the seal?"

The devil shook his head and said, "they are not looking for it, but guarding it."

Hearing the speech, ye Tian frowned and seemed to understand the clue. The demon king did not avoid suspicion and continued, "Ye Tian, I can tell you where the seal is."

"If it involves any secrets, you'd better stop talking. I'm not interested in your grudges and don't want to be involved again."

The devil smiled brightly and said, "it's no secret. Since you already know my plan, it doesn't hurt to know more."

After that, the devil took a deep breath and said slowly, "because the seal is underground of the f special police headquarters, I only have the opportunity to go in and uncover the seal if I mess up the whole Jincheng."

Ye Tian's heart was shocked and he completely understood the devil's intention. This guy's mind is really careful and his eyes are far-reaching enough. No wonder f special police will regard him as the most wanted criminal.

However, the only thing ye Tian doesn't like the devil is that he can sacrifice everything by any means in order to achieve his goal! Although Ye Tian is also a decisive person, he can sometimes be cruel. Such people also have fatal weaknesses.

Although Ye Tian knows, he will not have trouble as long as he is not involved in external disputes. The devil, on the contrary, as long as he can achieve his goal and sacrifice everything, it is worth it!

At this point, the two are diametrically opposed.

"Now, you should understand why I did this?" The devil asked again.

Ye Tian sighed and nodded, "well," you can go to the headquarters of F special police at any time, but now I have to catch a complaining bird back. "

"You still want to be my enemy?" The devil asked with narrowed eyes.

Ye Tian shook his head and said, "you think too much. I just catch a complaining bird. It will take some time to develop a vaccine. During this period, it will be enough for you to open the seal. We won't affect each other."

The devil frowned and thought about ye Tian's words in his heart. As a last resort, he doesn't want to be the enemy of Ye Tian. After all, ye Tian is a rare character. When he has to, the devil is never willing to screw up his relationship with him.

After thinking for a long time, the devil took a deep breath: "OK, I can let you take a complaining bird away, but ye Tian, don't forget that you promised me not to destroy my plan, otherwise, don't blame me for being impolite!"

"Threats are useless to me." Ye Tian shrugged and said, "as long as we don't affect each other's interests." After that, ye Tian said no more and turned out of the cabin.

At this time, there are many complaining birds flying in the sky outside. With his flexible skills, ye Tian soon caught one and put it in the cage prepared in advance.

Although the size of the complaining bird is small, it is very fierce. The complaining bird trapped in the cage flapped its wings and tried to break free.

Ye Tian glanced and said with a faint smile, "little thing, be quiet."

It was late at night when I came back from the chaotic graves in the suburbs. Ye Tian returned to the clinic alone and extracted the antibody he wanted from the body of the complaining bird. Now, as long as the antibody is sent to Qian Lao and others and the components are analyzed, the vaccine can be developed.

When the vaccine is put into use, it will take at least half a month. This half month should be enough for the demon king.

At this time, in the wooden house of luanfenggang on the outskirts of Jincheng. Zhou Xiao rubbed some dizzy head and couldn't help asking, "Lord, why didn't you kill Ye Tian for such a good opportunity just now?"

"Why, do you think killing Ye Tian is good for us?" The devil asked in a bland tone.

Zhou Xiao hesitated and said, "but now ye Tian knows all our plans, and he may develop a vaccine at any time. At that time, if he hinders our plan, he can..."

Speaking of this, Zhou Xiao's eyes looked at the demon king with a trace of temptation.

The corner of the devil's mouth raised a confident smile and said, "don't worry, even if ye Tian knows these, he won't do any harm to our plan. On the contrary, he will help us!"

Hearing the speech, Zhou Xiao was stunned. He didn't understand the meaning of the devil's words. When he was about to ask, the devil turned around: "Zhou Xiao, it's getting late. You should go back."

Zhou Xiao nodded. Although his heart was full of too many questions, he didn't dare to ask more. He could only say, "Lord, I'll go first."

The demon king "um" said, "you still have a task to go back this time."

Hearing this, Zhou Xiaodun stopped his steps and said respectfully, "Lord, what else is the task?"

"It's very simple. After you go back this time, monitor Ye Tian's every move." The demon king said lightly, "of course, you don't have to deal with him. Just don't let the vaccine be developed too early. When our plan is completed, let Ye Tian do it."

"Lord, ye Tian already knows my identity. I'm worried about him..."

As soon as he said this, the demon king had interrupted with a wave: "don't worry, as long as you don't take the initiative to provoke him, ye Tian will never expose your identity!"

Hearing the speech, Zhou Xiao was relieved and said in a deep voice: "Lord, don't worry, your subordinates will complete the task!"

The demon king nodded with satisfaction and said, "good, good, you can go back now!"

Zhou Xiao didn't hesitate. He got up and walked away in a hurry.

Early the next morning, ye Tian rushed to the hospital with the antibody extracted from the complaining bird. Qin Qingqing was busy here all night yesterday. Although Zhao Ji didn't dare ask her to help, Qin Qingqing was too proactive.

When ye Tianlai came, she had just finished her work and looked haggard.

Seeing her like this, ye Tian couldn't help shaking his head and sighing: "can't you be lazy?"

Qin Qingqing glared at him and said, "I think others are like you. Since I'm here to help voluntarily, of course I can't be lazy!"

"Sounds great!" Ye Tian smiled and said, "OK, it's all boiled into black circles. Go and have a rest quickly."

Qin Qingqing retorted a few words. He knew that ye Tian was concerned about himself. On the surface, he looked indifferent, but in his heart, he was a burst of sweetness.

At this time, old Qian also came out of the corridor. Seeing ye Tian, he hurried over: "Ye Tian, how's it going?"

Ye Tian nodded with a smile and said, "don't worry, Qian Lao, I've brought that thing!"

Hearing the speech, Qian Lao's face was pleasantly surprised: "really?"

Ye Tian handed a sealed vial to Qian Lao and said, "as long as you study the ingredients inside and then integrate them into the general vaccine, you can."

"Good guy, how did you do it!" Qian asked pleasantly.

"It's not too late to say this later." Ye Tian smiled faintly and said, "however, old Qian, if the vaccine is developed, don't rush to put it into the market first. It's not too late to announce it after a period of time."

Smelling the speech, a trace of doubt flashed in Qian's eyes. He couldn't help asking, "why?"

Ye Tian's doing so naturally did not want to cause a conflict between him and the demon king. Of course, he would not tell others the reason, but said, "I don't know if this vaccine has side effects on the human body. It's better to be safe!"

"Yes, yes!" Old Qian didn't doubt it and praised, "Ye Tian, it's really rare for you to have this sense of responsibility. There are really fewer and fewer young people like you now."

Hearing that Qian Lao praised Ye Tian so much, Qin Qingqing was a little dissatisfied and said, "he's not that good..."

Ye tiansa smiled and didn't care about anything. While talking, Zhou Xiao came from one side. Ye Tian just took a look. Zhou Xiao looked a little unnatural. But seeing that ye Tian didn't say anything, he was relieved.

"Ye Tian, come to the lab with me." After a while, old Qian said, "let's develop the vaccine together!"

Ye Tian shook his head, smiled and said, "old Qian, I won't go. There's no one at the clinic. I have to go back. In short, just tell me when the vaccine is developed!"
