Xu Qian reached out and picked up the box and said:

"That's it. Grandpa picked it up from a cave. I don't know what it was. I didn't even have a lock. I found many people but didn't open it."

Xu Qian held the jade box, looked at it for a long time, then shook her head and said:

"I really can't tell what's there. If you need it, take it. Grandpa, then I said that it's not a good thing, and Grandpa doesn't like it either. Once, I didn't open it after a long time of fighting, and Grandpa almost threw it away."

Liu Yu took the jade box and looked it carefully again. He confirmed that it was something from Qingyun Continent. He couldn't put it down and put it back and said:

"Xiaoqian, let's talk about it when your grandfather comes back! Oh by the way. What kind of disease is your grandfather? Why hasn't he cured for such a long time?"

Xu Qian threw the jade box heavily into Liu Yu's arms and said impatiently:

"Why is the big man like this? If you say you can give it to you. If you like it, take it. Mother-in-law and mother, it's so long-winded."

Doesn’t Liu Yu want it? no, he wants it very much. If he doesn’t know anyone, he might want to steal it.

On the earth without spiritual energy, this is definitely a priceless treasure. Liu Yu estimated that it might contain spiritual herbs that are difficult to see on the earth.

Such a precious thing, even if Xu Qian is his lover, Liu Yu cannot ask for it for nothing. Liu Yu said to Xu Qian gratefully:

"Xiaoqian, although I love you very much, I can't ask for your things for nothing. Let's do this. I'll take this jade box first. When the holiday is on, you will take me to see your grandfather and I will see if I can cure your grandfather's illness."

Xu Qian was startled by Liu Yu again, blinking her charming little eyes, looking at Liu Yu as if she was looking at an alien. Of course, Liu Yu was an alien!

Liu Yu was so furious that she saw her and teased her, "Why are you looking at me like this? You've seen me before. What were we still there just now?"

Xu Qian blushed and said:

"Are you serious? Xiaoyu? You can still see a doctor. God! How many secrets do you have?"

"No more, there is no secret at all. Now I am completely naked in front of you." Liu Yu said with a smile.

Xu Qian hugged Liu Yu, took a bite on Liu Yu's arm, and said charmingly:

"When did I learn so poorly and I'm not serious, to be honest. It's winter vacation in a few days. Let's go to Kyoto to see my grandfather." Liu Yu nodded.

Then he turned to the shelf where the books were stored and read a few medical books. Among them, there was a broken book that could not be more old. Liu Yu was stunned when he opened it.

The words in this book were actually written by Qingyun Continent, which was a book about practicing medicine. Liu Yu quickly read it, with his powerful memory now.

It only takes one time to write it down. This was written by a famous miracle doctor on Qingyun Continent.

It mainly treats various complex diseases and various strange diseases. Traditional Chinese medicine, which is somewhat similar to Chinese, requires silver needles and true qi to assist in the treatment.

There are also various detoxification methods and books on refining some pills. I really don’t know how this book was spread to the earth.

Before Liu Yu could speak, Xu Qian introduced:

"This book is also from Grandpa. It is obtained in the same place as the jade box in your hand. No one knows the text on it, and it is not an antique, so I throw it here."

Speaking of this, Xu Qian looked at Liu Yu and continued:

"Grandpa said that if anyone can recognize the words in the book, he will give them to anyone if he wants them. Anyway, he doesn't know the words on it and can't understand them. It's useless to keep them."

Liu Yu knew that what Xu Qian said was true, and it was impossible for anyone on Earth to recognize the words on Qingyun Continent.

Unless there are people from Qingyun Continent who come to Earth, it will be troublesome if that happens. Thinking of this, Liu Yu said to Xu Qian cautiously:

"Xiaoqian, don't mention this matter to anyone. I will hold the jade box and destroy this book." After that, Liu Yu sent out a wisp of true energy and turned the medical book into a handful of dust.

Xu Qian looked at Liu Yu in surprise, without blaming him, just said;

"Do you know the words in this book?"

Liu Yu nodded and said, "It's really something from the cultivators of Qingyun Continent. People must not know about it, as the consequences will be very serious."

"Oh" Xu Qian nodded in a slight way. The two of them walked out of the collection room, and Xu Qian locked the door again.

After returning to Xu Qian's bedroom, the two chatted for a while, and Liu Yu coaxed Xu Qian to sleep, left a note and left. This path was nothing to Liu Yu.

The speed of the divine walking is similar to a taxi, but he can only take a few people on the road, and Liu Yu did not return to the taxi.

Instead, he chose to go directly to the cave in the North Mountain. He wanted to see what was in the jade box.

After coming to the cave, Liu Yu did not open the jade box at the place where he practiced just in case, but instead found a relatively hidden and smaller hole.

There are many small caves in the big cave, all of which are naturally formed. The one Liu Yu found is a little larger than the other caves, with a size of more than 20 square meters.

Then, he took out the jade box, looked carefully at the ban, and began to use his spiritual sense to try to untie it.

As a result, he felt dizzy again. Liu Yu knew that his spiritual consciousness was still a little weak. He temporarily put down the jade box and started practicing.

Another big circumference. Three small circumferences passed by. Liu Yu felt refreshed and the true energy in his body increased a lot.

I wanted to untie the ban on jade box again, but the result was still not, it was just a little bit short of it.

There was no choice but to give up the jade box for the time being and start practicing again. Three hours passed. Liu Yu opened his eyes and punched another set of punches.

Seeing that the sky was about to dawn, I took a step forward and returned to the rental house. Liu Yu decided to go to the Chinese medicine shop to buy some medicinal materials first and strengthen auxiliary practice.

Due to the lack of spiritual energy on the earth, it is useless to practice foolishly. If you do it, Liu Yu decided not to go to class today and buy medicine first.

After lying in bed for a while, when the pharmacy opened, Liu Yu and I switched to several Chinese medicine stores, bought dozens of Chinese medicines, and then returned home after buying them.

The medicinal materials are very expensive, and almost cost Liu Yu 40,000 yuan. In this way, Liu Yu added the money given by Liu Ling, so that the money given by Liu Ling was only more than 10,000 yuan.

It seems that I have to save money. I am afraid I will have to live a hard life again after spending money with big hands.

Liu Yu was afraid that others would see it, so he sneaked into the cave and spent a day and night to refine some simple pills.

Without spiritual herbs, Liu Yu could only refine these things. Seeing the results of his refining for a day and a night, Liu Yu couldn't help but shake his head and smile bitterly.

There are Huxin Pills, Zhenqi Pills, Qingshen Pills, and some simple pills. They are simple here in Liu Yu, but they are definitely not visible on earth.

If Liu Yu hadn't read the medical book in the cultivation world of Xu Qian's family, he might not have been able to refine these things, because he has not practiced enough now.
