Qu Jiujiu thought about this question for a long time, but he couldn't find the answer. He thinks that even if the method is wrong, what he needs to do now is to increase the efficacy and develop new drugs.

But sometimes people encounter more difficulties, it will be more and more fierce, when he is in the trough, that is, when he climbs up, it is time to go uphill.

At this time, no one can know how uncomfortable Zhang Cheng is in his heart. Zhang Cheng doesn't want to show the weakest side of his heart. Everyone knows that it's a great blow to him.

After Kang Zhimian's death, Zhang Cheng suffered a great impact, but he still had to make up his mind to find a new way to treat those who were infected by evil Qi. So that he can be worthy of the people who help him.

But this time, Zhang Cheng made up his mind never to do this again. There was no guarantee experiment. He was afraid to take the risk.

Zhang Cheng came to Qu Jiujiu's room and they exchanged the experience of this treatment, hoping to find a way to learn from it. Qu Jiujiu poured a cup of tea for Zhang Cheng.

"Don't be discouraged or sad any more. We don't want this to happen, but it has happened, and we have to go on. Only when we really find a way can we be worthy of him. " Qu Jiujiu handed the tea to Zhang Cheng and said.

Zhang Cheng looked up and saw Qu Jiujiu with a bad face. He knew that now he had to be strong and go to the next step immediately. There is no time to be sad now.

"I know that I just really blame myself. Why did I promise him to do it at that time? If..." Zhang Cheng said.

At this moment, both of them are very confused. They don't know what causes this situation. The reason is complicated.

"When I was healing him, I tried my best to get rid of all the weapons, but when I got rid of the last tacit understanding, the medicine suddenly stopped, which made his body hurt by aura." Zhang Cheng said to Qu Jiujiu.

"I don't understand why that is." Zhang Cheng said.

In front of the table, Qu Jiujiu looks up and holds his arms. He went to the window and looked into the distance at the green leaves, lost in thought.

"I've been thinking about it all the time. I don't know whether it's my medicine or your method. I can't make a judgment now." Qu Jiujiu said quietly.

At this time, both of them are like a headless fly. They can't find out what is the reason. It's a big headache for both of them.

"Well, I'll continue to increase my dosage to make it more lasting. You can improve your method. This is the only thing we can do. We can make up for the biggest mistake by combining the two." Qu Jiujiu said to Zhang Cheng.

At this time, Zhang Cheng also agreed with Qu Jiujiu, because they really had no way to hesitate too much. Zhang Cheng went to the place full of demons to check. Qu Jiujiu continued to study new drugs.

After two days of unremitting efforts, Qu Jiujiu finally developed a new drug, which can make the efficacy more lasting. That is to say, there is more time to remove the grinding gas.

After the drug was developed, Zhang Cheng was immediately informed that they were ready to carry out the next experiment. But the next experiment is difficult to carry out.

Because Zhang Cheng has forbidden ordinary people to come to test drugs, because the risk of this practice is too high, the security is also very low, the risk is too high, failure is a life.

Just when Zhang Cheng and Qu Jiujiu were worried, Li SHIMENG suddenly came here.

"Why, what are you two worrying about? Let's see if I can help you," Li SHIMENG said to them.

Zhang Cheng and Qu Jiujiu, seeing Li SHIMENG coming, have not seen him for a long time, so they feel a sense of reunion.

"How did you come here, why did you come here, what did you do here?" Qu Jiujiu asked. Zhang Cheng watched Li SHIMENG push the door.

In fact, Li SHIMENG has known for a long time that they have been conducting experiments, but they have failed twice. He wanted to make sure that no one was willing to volunteer. So he wanted to come and help Zhang Cheng.

"I already know about you, and I think you know what I'm here for. I think maybe I can help you." Li SHIMENG said.

At this time sitting Zhang Cheng suddenly stood up, he was actually very surprised, he would say so. He had no idea that the woman in front of him would come here.

"No, you can't, and I won't agree with you. It's too dangerous. If you don't have anything else, you'd better go back." Zhang Cheng said to Li SHIMENG.

"I'm sure I'll be OK. Besides, if I really fail, you can save me the way you did last time, don't you think so?" Li SHIMENG said to Zhang Cheng.

At this time, Zhang Cheng didn't say anything. He just turned around. He didn't want to agree to Li SHIMENG's request. He didn't want to block his life.At this time, Qu Jiujiu went to the window, the breeze blowing his hair. He's trying to make a decision. He felt that Li SHIMENG's request could be accepted.

"I think we can try again. This time we are guaranteed. If not, we will never be able to do it again." Qu Jiujiu went to Zhang Cheng and said.

Zhang Cheng looked at the blue sky. He didn't know what he should do at this time. He was afraid, but he wanted to develop a way to save more people.

"Well, I promise you, no matter what, we must succeed this time. There is no failure." Zhang Cheng raised his head and said.

Li Shi dreams of their promise and feels that she can finally help them. There was an indescribable joy in his heart. He didn't know how to describe it.

Before the beginning of the experiment, Li SHIMENG had to be eroded by him for three days to reach a therapeutic level, just like Kang Zhimian.

Zhang Cheng accompanied Li SHIMENG to this magical environment. Zhang Cheng is with Li SHIMENG. He didn't want to make him feel lonely without company.

It is a very painful thing to be eroded by the evil spirit. It can be said that without strong perseverance, it is impossible to succeed. Lost dream sitting there. Beany beads of sweat came down from his forehead.

In his eyes, Zhang Cheng uses his aura to help Li SHIMENG alleviate his pain.
