When Chu Nan knocked on the door before, the biochemical virus in her body happened to attack. She wanted to open the door for Chu Nan, but she couldn't move for a while, and then suddenly fainted.

"Drink a little water."

Chu Nan brought a cup of warm water and handed it to Hong Xiaochen's mouth.

Hong Xiaochen took a sip and felt much more comfortable in his throat.

"Chu Nan, thank you."

Hong Xiaochen squeezed out a smile of gratitude. Just as he was about to stand up from the bed, he found that Chu Nan had picked up the martial arts secret book that Wang Kaian gave him.

"Xiao Chen, this secret book..."

Chu Nan was about to ask what happened to this secret book, but was interrupted by Hong Xiaochen urgently: "This secret book is a misunderstanding. It was given to me by Wang Kai'an. He said that it could cure my disease, but I don't know if it is true or not."

Hong Xiaochen's pale pretty face crawled up with a bright red look, for fear that Chu Nan would think of him wrongly.

Chu Nan smiled faintly. What Hong Xiaochen said was really exactly the same as his reasoning.

But if this secret book is really like Wang Kaian said, wouldn’t Hong Xiaochen’s illness be saved?

Realizing this problem, Chu Nan's face suddenly became serious: "Xiaochen, do you think this is good? I will take this secret book back for professionals to study and study. You can wait for my results at home first. If it really works, I will notify you as soon as possible."

"ah!?"

Hong Xiaochen was slightly stunned. He just said casually and did not intend to let Chu Nan test the authenticity of this secret book. Even if it was true, so what?

From beginning to end, I didn't plan to practice this kind of despicable martial art with Wang Kai'an.

But now, Chu Nan has taken it seriously, what else can he say?

I could only watch Chu Nan leave with the secret book hurriedly.

However, seeing Chu Nan cares so much about his body, Hong Xiaochen's heart is still warm.

At least in this world, there are people who really care about themselves.

With the secret book, Chu Nan quickly rushed to Old Charlie's laboratory.

At this moment, Old Charlie seemed extremely excited. When he saw Chu Nan coming, he hurriedly stopped the work at hand.

"Old military doctor, you look in a good mood today. Are you having any latest research results?"

Chu Nan asked with a smile.

"Yes, I just carefully studied the biochemical virus. I found that although I cannot completely overcome this virus at this stage, the hardcover Huili Pills produced by our Huayue Pharmaceutical can temporarily inhibit the spread of the virus after I improved it. In this way, your friend will not be in danger of life."

Old Charlie was so happy that Hong Xiaochen's condition has always been a knot in his heart. Now that he has recovered, he has finally found some solutions.

"Okay, you did a great job!"

Chu Nan couldn't help but patted Old Charlie on the shoulder, and was also very excited about the news.

By the way, he handed over the secret book he brought from Hong Xiaochen: "Old military doctor, see if this secret book has an inhibitory effect on biochemical viruses. If there is one, it would be even better."

Old Charlie took the secret book curiously and looked at it. After just turning a few pages, the expression on his face gradually became solemn.

"What? Is there anything wrong with this secret?"

Chu Nan felt a little nervous. This was the first time he saw Old Charlie's expression so heavy.

"This secret book is quite mysterious, but the content is a bit unhealthy..."

Old Charlie showed a little embarrassed. People as old as him were, seeing such dirty content was really unacceptable.

But the more you look back, the more you feel that the secret is magical.

It looks like a martial arts secret, but when you disassemble it, it contains many medical things.

This fascinated Old Charlie.

"What's the matter with the old military doctor? Are you saying something happy?"

Chu Nan looked helpless, and didn't know if Old Charlie was attracted by the yin and yang dual cultivation in the book, or why, he ignored him.

I don’t know how long it took, but Old Charlie closed the secret book with an unfulfilled desire and said, “Good books, what a good book. I didn’t expect there would be such a magical way to practice the mind in this world!”

"Old military doctor, didn't you just say that the content was a bit unhealthy? Why do you think it's amazing again now?"

Chu Nan was so amused that the old man came out from the left and the right, and he didn't know which sentence was true.

Old Charlie scratched his head awkwardly: "This... although the content is not very healthy, it cannot be denied that this is a good book. If it has been improved by me, I believe this book will definitely have another magical feature."

Chu Nan hummed and smiled: "Old military doctor, I'm asking if this book has any inhibitory effect on biochemical viruses. What's the use of you and me?"

"Chief, don't worry first, let me study it and then give you a reply."

Old Charlie knew that Chu Nan was impatient and was too lazy to explain so much to Chu Nan. He took out a neutral pen and rewritten it on the secret book.

Seeing that Old Charlie was so serious, Chu Nan could not disturb him anymore, so he simply lay on the chair and rested.

I haven't had a good rest these two days. Chu Nan was very physically and mentally exhausted. She fell asleep in a short while after lying on the chair.

It was not until more than half an hour later that Chu Nan was woken up by the excited old Charlie.

"What are you doing, old military doctor, what's wrong with you?"

Chu Nan rubbed his eyes in a daze, so sleepy that he was dying.

"Chief, this book has been modified by me so much. Let's try the effect quickly. I'm also curious about what this book can transform the human body into!"

"What did you say!?"

Chu Nan suddenly became energetic and felt as if he was hallucinating. He couldn't help but confirm: "Old military doctor, are you not kidding? Do you want me to practice this book with you?"

"Yes, is there any problem?"

Old Charlie didn't understand why Chu Nan reacted so much, and his face was extremely innocent.

Chu Nan swallowed and vomited, and was really scared by Old Charlie's words. She covered her sweaty forehead: "Old military doctor, we are both men, how can you let me do such a thing with you? If you really have that idea, I can find you a woman..."

"Well……"

Old Charlie was confused by Chu Nan's words, but he quickly understood what was going on. He couldn't help but smile and said, "Chief, you misunderstood. This book is now changed by me, and it doesn't need to blend yin and yang at all. It just needs to practice with opponents."

"Ah, if that's the case, then that's OK!"

Chu Nan touched the fine sweat on her forehead, and was almost scared to death by Old Charlie just now.

But I can't blame myself for this. Who made Old Charlie not say it clearly? How can I not think wrong?

However, Chu Nan had to admit that Old Charlie was capable.

This old guy is really awesome.

After his improvement, the secret book seemed to have become a spiritual method that defies the heavens.
Chapter completed!
