Everything was actually clear when Zhao Tiezhu held Cao Ziyi's hand. Zhao Tiezhu learned something. When his parents were doing research, they focused on medical biology. When Zhao Tiezhu was young, he also learned some basic Chinese medicine with his grandfather. Later, he went abroad and even met a master of traditional Chinese medicine abroad and learned some skills.

Cao Ziyi's palm was sweating slightly, and the qi and blood all over her body seemed very poor. Zhao Tiezhu knew that Cao Ziyi had suffered internal injuries.

Why did Cao Ziyi leave in the middle of the night? Cao Ziyi's sobering medicine saved his people when he killed Li Tianfeng, and Zhao Tiezhu was able to connect everything together in an instant. Zhao Tiezhu could almost guess the general truth of the facts.

"My parents asked you to come?" Zhao Tiezhu asked softly.

"Well, uncle and aunt are worried about you." The expression on Cao Ziyi's face did not change at all, and she still leaned calmly on Zhao Tiezhu's shoulder.

"Oh...you should know what happened last night, too." Zhao Tiezhu asked.

"Know."

"Cyan Dragon hurts you?"

"Yes."

A murderous aura suddenly burst out in Zhao Tiezhu's eyes, and he shook his head, "I can't beat him now."

"I can wait. You can beat him soon." Cao Ziyi smiled sweetly.

"Haha, that's it. One day I will beat Qinglong down and sing to conquer you, you must agree with me." Zhao Tiezhu also said with a smile.

"Hehe" Cao Ziyi smiled.

"Ziyi, are you very awesome?" Zhao Tiezhu was silent for a while and suddenly asked.

"Better than you." Cao Ziyi said seriously.

"Tsk, I'm almost capable of surpassing the third place in the dragon list now. Can you be better than me?" Zhao Tiezhu shook his head in disbelief.

"Last night, Qinglong was ruined by me." Cao Ziyi said lightly.

Zhao Tiezhu was shocked, as if he was struck by lightning.

"You...you said you had destroyed Qinglong's hand??" Zhao Tiezhu said in disbelief.

"Well, Qinglong is a left-handed person, I can only destroy his right hand, but I was injured, which is worse than him." Cao Ziyi's face suddenly showed a look of unyielding expression, "If I hadn't been completely inspired, I wouldn't have been so seriously injured."

"Then why don't you go to the hospital for a quick look?" Zhao Tiezhu said anxiously.

"No need, I have medicine here, uncle and aunt give it to me." Cao Ziyi smiled and took out a small box from the side. After opening it, there were capsules inside the box.

"Are these researched by my parents?" Zhao Tiezhu picked up one and looked at it. It was no different from the usual capsules.

"Yes, uncle and aunt are the world's top biologists. Although this medicine cannot cure me immediately, it can speed up my body's metabolism dozens of times, which is much more effective than going to the hospital." Cao Ziyi replied.

"Then I will be able to recover today, because of this?" Zhao Tiezhu asked.

"No, do you remember the sobering medicine you drank last time? It was developed by uncles and aunts. There are only two top-notch medicines in the world, one z1 and the other z2. The one you drank last time was z2."

"What about z1?"

"For me, the effect of z2 is the same as z1, but the uncle and aunt added an uncertain factor into z2, saying that it was studied from a domino, and I don't understand it either."

"Domino?" Zhao Tiezhu was shocked again. His father had a domino. He knew, but what is the secret about dominoes that can be added to the potion?

"Yes, uncle said that dominoes were passed down from ancient times. There is a secret inside that uncle could not find. He just calculated a factor equation from it. According to uncle, this uncertain factor is an evolutionary factor. It can lurk in your body with your potion to a certain extent. After reaching certain conditions, your body will evolve, which is much better than z1."

Zhao Tiezhu frowned. His father could deduce the equation if he had only one domino. If all dominoes were assembled, would he deduce 12 equations? If all the 12 equations appeared, what would happen? 2012 is coming? Or would he transform into Superman? Zhao Tiezhu was not clear and had a headache thinking. Zhao Tiezhu sighed and stopped thinking about him.

"Tell me again about my parents." Zhao Tiezhu asked.

"I don't know very well about it. Do you still remember that you were struck by lightning back then?" Cao Ziyi covered her mouth and smiled.

"I know! Could it be that my parents arranged it?" Zhao Tiezhu asked in surprise.

"Yes, you were using the Z0 potion at that time, and an uncertain factor was added to it. Later, you directly had the ability to invisible. However, the evolution of this uncertain factor was too poor, so later, after you were injured, it disappeared."

"Then, can I give me a supernatural ability for this uncertain factor now?"

"Who knows this?" Cao Ziyi said with a smile, "Actually, uncles and aunts have always missed you."

Zhao Tiezhu sighed, "I don't know when they will come back."

"It's almost done." Cao Ziyi whispered, "A year at the latest."

Zhao Tiezhu and Cao Ziyi sat there and talked a lot. Zhao Tiezhu also had a certain understanding of some of the things that happened in the past. As for the turmoil, Cao Ziyi was like Mr. Zhao. She didn't say much, but asked Zhao Tiezhu to wait until his parents came back before asking.

What Zhao Tiezhu didn't know was that Cao Ziyi was very relaxed when she said it. In fact, the Z-series potions were so easy to absorb? Every time Cao Ziyi tried the medicine for Zhao Tiezhu, it was really a life-and-death life. Only when Cao Ziyi tried it and there was no rejection reaction, would she use it for Zhao Tiezhu. Cao Ziyi just kept smiling and chatting with Zhao Tiezhu. Cao Ziyi chose to forget these things.

It was a joyful chat here, and Zhao Tiezhu's phone rang again. Zhao Tiezhu was so depressed that he finally could be alone with Sister Ziyi, and then he discovered such a big secret. He was about to learn more about each other, deepen his feelings, enhance friendship, and lay the foundation for future development. Since this call, it has been interrupted directly, and Zhao Tiezhu answered the phone in annoyance.

"Brother Tiezhu, Qingdi has found it." Tie Hand's voice came from the other end. Zhao Tiezhu was stunned and said, "I understand, I'll go there now."

After hanging up the phone, Zhao Tiezhu said to Cao Ziyi, "I have something to do, I have to go out and you can rest well."

"Well, I will." Cao Ziyi said with a smile, "You have to be careful."

"Well, by the way, my grandfather told me that you are the material for a big house." Zhao Tiezhu said with a smile before leaving.

"Haha." Cao Ziyi smiled faintly and did not respond. Zhao Tiezhu sighed with frustration, "Okay, I won't joke with you anymore, let's go."
