Tang Qian'Er wanted to say something, but was cut off by Zhang Yu. He looked at Tang Qian'Er and said:

"Big Sister Qian'Er, now isn't the time to think about me. I went out this time for the sake of a little plan. If possible, I believe he'll be fine this time …"

"Really?"

Tang Qian'Er said in surprise.

"Mm. Believe me, Sister Qian'er, she will!"

Definitely!

Zhang Yu bid farewell to Tang Qian'Er. Then, he called a taxi and headed straight for his home.

"Grandmother!"

Zhang Yu, who had yet to enter the house, was already shouting 'Grandma' outside the door. The door opened with a creak. Zhang Yu's grandmother stared at Zhang Yu with his blurry eyes and said happily:

"Little Chen, why did you come back today? Weren't you staying at school? Could it be that you're on vacation?"

"Holidays?"

Zhang Yu said in doubt.

"Yeah, didn't you say that you would stay at school in the future so that you could study?"

Grandma Zhang explained. It suddenly dawned on Zhang Yu that Sister Qian'er had given him such a panic, so he quickly answered:

"Yes, I was at school. Grandmother, come in and tell me that I have something to talk to you about."

"Alright, let's go inside."

After saying that, Zhang Yu supported Grandma into the house.

"Grandmother, does our family have an ancestral medical book?"

Zhang Yu entered the house and sat down. He impatiently asked his own question. Grandma Zhang's hand trembled when she heard his words.

"How do you know …" Oh, what medical book is it? Why don't I know about it? "

Although she was shocked, she quickly changed her words. Zhang Yu could see the elder's expression changing again and again. It seemed that there was a story behind her own medical book.

"Grandmother, I saw it when I was at home. I saw that someone had some kind of mystical medical skill, so I hope they can save me."

Zhang Yu said firmly. Grandma Zhang's face did not look too good as she retorted:

"This won't do. That book definitely can't be born. There will be great trouble. Little Chen, it's best if you forget about it as soon as possible, sigh …"

Zhang Yu could see the expression on his grandmother's face, but he still braced himself and said:

"Grandmother, it's just a small matter. Right now, he's unconscious. If it wasn't for the medical skills in the book, he might never have woken up again."

He would never wake up. In the elder's heart, he was a symbol of death.

"What?"

Grandma Zhang exclaimed.

"Speak of the Child? "What happened to him? What happened? Why have I not heard of that little girl Qian'Er mentioning him before?"

Afterwards, Zhang Yu roughly told Grandma Zhang what had happened recently. He didn't mention him, but only mentioned that Yuanzhi had been taken care of in order to save his sister. Now, his life was in danger. After hearing Zhang Yu's words, Grandma Zhang fell into a period of silence. After a long while, she sighed and said:

"Whatever, I'll just give it to you. Little Ji is a good child!"

Zhang Yu said excitedly:

"Thank you, Grandma!"

"Alright, come with me." Turning around, he led Zhang Yu into the kitchen. Grandma Zhang dug around under the kitchen counter for a while before she brought out a one-foot square metal box and said:

"This is it. The thing you want is inside. Remember, don't let anyone else know. Our home …"

She wanted to say something but hesitated. In the end, she sighed and turned around to return to her room …

"Ai, I really don't know if this is a blessing or a curse …"

"Grandmother …"

Zhang Yu wanted to stop her, but his grandma just waved her hand and said that she wanted to rest, so he could only hold the box and ponder it for himself.

Opening the metal box, he saw the black wooden box that Zhang Yu was familiar with. He knew what was inside, so he carefully took it out, and then a black box appeared below it. Opening it, he saw an ancient book lying inside.

The first time Zhang Yu saw it, he realized that this manual was different from the one he had seen in his previous life. It wasn't because of the difference in content, but because he felt that the first thing he saw after flipping through the book was a platform — — "Monastery", "Theory of Injuries", "Thousand Gold Formula", "Immortal Dao". "As he looked at the words that appeared before his eyes, Zhang Yu was very confused; the copy he had seen in his previous life didn't have this final" Immortal Dao ".

Flipping through the last page, Zhang Yu realized that there were no words on it at all. In other words, it was empty to begin with? Because many places in the book mentioned that "spirit", "using spirit as support", and "channeling into the body", before he didn't understand the meaning of spirit, so he thought that there were many methods in the book that had no effect. Now, it seems that the spirit was the key, and this spirit was definitely referring to spirit energy. Without the assistance of spirit energy, no wonder many prescriptions were ineffective, it seems that this is a medical book prepared for cultivators, no wonder he dares to call himself a god of medicine.

"Brat, the book in your hands is really extraordinary."

A sudden voice interrupted Zhang Yu's thoughts.

"Yan, why did you come out?"

He jumped in shock and turned around to look at the little fire dragon floating beside him.

"Did I say I can't come out? "You are all idiots!"

Fine, I must be an idiot. I've never seen it come out and I don't know if I can prove it to be there or not.

"Yan, I also know that this book is not ordinary. This is a medical book prepared for cultivators, of course it is not ordinary."

Yan glanced at him again. It knew what Zhang Yu was thinking of — Idiot.

"If you can see such an obvious thing, can't I see it? I mean, this book has another trick to it!"

Yan walked around the medical book and said,

"Something else?" "Where?"

"Hmph, kid, circulate your Scorching Sun Spell and pour the Spiritual Energy within your body into the book!"

"Inject spiritual energy into the book?" "It can't be that the book is destroyed, right? The fire spiritual force in my body!"

Zhang Yu was puzzled and surprised. However, when he saw the way Yan looked at him, he gave in.

Circulating the Scorching Sun Spell, he injected a bit of fire spirit energy into the medical manual. With this, he opened a certain door, and it was still the entrance to the abyss. A strange suction force arose from the book, crazily devouring the spirit energy within his body.

He wanted to shake it off, but he found that the medical manual was stuck in his hand, unable to tear it off. He was so anxious that he cried out for help, otherwise, he would have been sucked dry.

But after reading for a while, he saw the medical manual absorb all the spiritual energy in Zhang Yu's body and stop absorbing it from within his body. Instead, he used the Scorching Sun Spell to convert the spiritual energy from the outside to spiritual energy and then absorb it again. The speed at which the medical manual used the Scorching Sun Spell was many times faster than Zhang Yu's circulation.
