Everything, in fact, when Zhao Tiezhu's hand was holding Cao Ziyi's hand, Zhao Tiezhu was clear. Zhao Tiezhu has learned something, when his parents were doing research, they were mainly in medical biology, Zhao Tiezhu also followed his grandfather to learn some basic Chinese medicine when he was young, and later went abroad, but also met a Chinese medicine saint abroad, and learned a little craft.

Cao Ziyi's palms were slightly sweating, and the qi and blood all over her body looked 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 pills, the person who saved him when he killed Li Tianfeng, Zhao Tiezhu was able to connect everything at once. The general truth of the facts, Zhao Tiezhu can almost guess it.

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

"Hmm. Uncle and aunt can't rest assured of you. The expression on Cao Ziyi's face did not change at all, and she still leaned calmly on Zhao Tiezhu's shoulder.

"Alas...... You should know what happened last night. Zhao Tiezhu asked.

"Yes."

"Qinglong hurt you?"

"Yes."

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

"I can wait. You'll be able to beat him in no time. Cao Ziyi smiled sweetly.

"Haha, that's it, one day when I beat the green dragon down and sing to conquer, you have to make a promise." Zhao Tiezhu also said with a smile.

"Hehe" Cao Ziyi smiled.

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

"Better than you." Cao Ziyi said very seriously.

"Cut, I'm almost third on the dragon list now, can you be better than me?" Zhao Tiezhu shook his head in disbelief.

"Last night, Qinglong was deprived of one of my hands." Cao Ziyi said lightly.

Zhao Tiezhu's whole person was shocked, as if he had been struck by lightning.

"You...... You said you wasted one of the green dragons' hands??? Zhao Tiezhu said in disbelief.

"Well, Qinglong is left-handed, I can only scrap his right hand, but I am also injured, more serious than him." Cao Ziyi's face suddenly flashed with a look of unyielding, "If I hadn't been completely stimulated, I wouldn't have been so seriously injured." ”

"Then why don't you go to the hospital quickly?" Zhao Tiezhu said anxiously.

"No need, I have medicine here, and my uncle and aunt prepared it for me." Cao Ziyi smiled and took out a small box from the side, and after opening it, the box was filled with capsules.

"My parents researched these?" Zhao Tiezhu picked one up and looked at it, it was no different from an ordinary capsule.

"Yes, my uncle and aunt are the top biologists in the world, although this medicine can't make me heal immediately, but 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 can recover today because of this?" Zhao Tiezhu asked.

"No, do you remember the sobering medicine you drank last time, it was developed by your uncle and aunt, the top medicine, there are only two in the world, one Z1 and one Z2, the one you drank last time was Z2."

"What about Z1?"

"Z1 is here for me, and the effect of Z2 is the same as Z1, but Z2 was added by an uncle and aunt to an uncertain factor, saying that it was studied from a domino, and I don't understand."

"Dominoes?" Zhao Tiezhu was shocked again, his father had a domino, he knew it, but what secrets were there on the domino that could be added to the potion?

"Yes, Uncle said, the dominoes were handed down from ancient times, and there is a secret in it, and Uncle didn't find out, but he calculated a factor equation from it, according to Uncle, this uncertain factor is the evolutionary factor, and he can lurk in your body to some extent, together with your potion, and after reaching certain conditions, it will make your body evolve, which is much better than Z1."

Zhao Tiezhu frowned, his father only has one domino, what kind of equation can he deduce, if all the dominoes are gathered, will he be able to deduce 12 equations? What happens if all 12 equations appear? 2012 is coming? Or transform into Superman? Zhao Tiezhu didn't know, he had a headache when he thought about it, Zhao Tiezhu sighed and stopped thinking about him.

"Tell me about my mom and dad." Zhao Tiezhu asked.

"Specifically, I don't know very well, do you remember when you were struck by lightning?" Cao Ziyi covered her mouth and smiled.

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

"Yes, at that time, you used the Z0 potion, and an uncertain factor was added to it, and then it directly gave you the ability to become invisible, but the evolutionability of this uncertain factor was too poor, so later, after you were injured, it disappeared."

"Then I'm uncertain now, can I still give me an ability?"

"Who knows?" Cao Ziyi said with a smile, "Actually, my uncle and aunt have always missed you." ”

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

"It's coming." Cao Ziyi said softly, "One year at the latest." ”

Zhao Tiezhu and Cao Ziyi sat and talked a lot, Zhao Tiezhu also had a certain understanding of some of the things that happened before, as for that **, Cao Ziyi was the same as Zhao Lao, he didn't say much, just asked Zhao Tiezhu to wait for his parents to come back and ask.

What Zhao Tiezhu didn't know was that Cao Ziyi was very relaxed when he said it, in fact, how could the Z series of potions be so easy to absorb? Every time Cao Ziyi tried Zhao Tiezhu, it was really a life of nine deaths, only if Cao Ziyi tried it and there was no rejection reaction, he would give it to Zhao Tiezhu, Cao Ziyi just kept smiling and chatting with Zhao Tiezhu, for these things, Cao Ziyi selectively forgot.

The conversation was having a good time here, Zhao Tiezhu's phone rang again, Zhao Tiezhu was depressed, he was finally able to be alone with Sister Ziyi, and then he discovered such a big secret, and he wanted to get to know each other more, deepen his feelings, enhance friendship, and pave the way for future development.

"Brother Tiezhu, the Blue Emperor has found it." The voice of the iron hand came from the other end, Zhao Tiezhu was stunned for a moment, and said, "I know, I'll go over now." ”

After hanging up the phone, Zhao Tiezhu said to Cao Ziyi, "I have something to do, I have to go out for a while, you can recuperate." ”

"Well, I will." Cao Ziyi smiled and said, "You have to be careful. ”

"Well, by the way, my second grandfather told me that you are the material for making a big house." When Zhao Tiezhu went out, he said with a smile.

"Huh." Cao Ziyi smiled faintly and did not answer. Zhao Tiezhu sighed in frustration, "Okay, I'm not kidding you, let's go." ”

"Hmm." Cao Ziyi nodded, picked up the book and continued to read.
