Chai Shao's dormitory in the royal palace was better than ordinary guards. He had a separate courtyard with a tall locust tree in the courtyard. It was mid-spring, and the locust tree was lush and lush, covering the house as paved as a cover.

The dormitory is divided into two rooms inside and outside, with the inside being a dormitory, and the outside being a study and living place.

"Brother Si's dormitory is good, it's better than mine!" Zhang Xuan smiled at the old locust tree above his head.

He had just moved, and like Chai Shao, he also had two houses inside and outside, but the yard was empty and there was a big tree.

"If you like it, let's change the dormitory. You can't imagine the troubles caused by this big tree. Every morning, the black birds are noisy, and sometimes I want to swing an axe and chop it."

"Then let it go! Sichang keeps it for himself to enjoy it, I'm just talking."

The two of them entered the room with a joke. Chai Shao closed the door, smiled mysteriously, took out a wooden box from the box and handed it to Zhang Xuan, "This is a good thing! I took a lot of effort to get it."

Chai Shao did not fully comply with Dou Qing's instructions. Dou Qing asked him to give Zhang Xuan a roundabout way, but Chai Shao wanted this favor.

"This is--"

Zhang Xuan took the box and felt it was heavy, and he felt it weighed at least three or four pounds. When he opened the box, there was a blue stone slab inside, as smooth as jade, engraved with patterns and words. After closer inspection, it turned out to be a way to practice.

"Don't ask me where I got it. I will only tell you that this kind of exercise is called the Bluestone Sutra. It can be practiced as a gathering method in the acquired day, which is very suitable for you. And some people have achieved three breakthroughs in this exercise."

Zhang Xuan gently stroked the smooth stone slab, and felt deeply moved. He knew the value of this bluestone slab.

He has been in the Yan Prince's Mansion for a month. He originally hoped to learn the clever method of gathering strength from the Yan King, but gradually he realized that the method of gathering strength was only passed down from generation to generation between father and son, and would not be taught to outsiders at all. Moreover, it is very difficult to practice this method of gathering strength. It is not possible to practice it by getting a piece of exercise. It also requires people who have experienced it to teach a lot of practical experience.

His determination to practice martial arts was already a little shaken, but since he obtained Luo Shixin's Overlord Swordsmanship, he truly understood the importance of the method of gathering strength.

Overlord's marksmanship not only requires great power, but also unpredictable speed. The basis of speed lies in strength, from extremely slow to extremely fast, from half-speed acceleration to half-speed deceleration, all of which cannot be separated from the adjustment of power.

Without the method of gathering strength as the basis, he could not practice Luo Shixin's overlord marksmanship. Just when he was at a loss, Chai Shao gave himself a crucial gathering technique. Why didn't Zhang Xuan feel grateful?

He knew that this kind of exercise was hard to come by, especially the exercises that could be practiced after tomorrow, which were extremely precious. Perhaps there were only a few things in the world.

"Brother Chai's great kindness, I'll accept it, and I'll repay you later!"

Chai Shao was also a little ashamed, patted Zhang Xuan on the shoulder and smiled, "You don't have to thank me so much. Actually, someone gave it to you specifically, and I'm just passing it on my behalf."

"Who is it?" Zhang Xuan asked in confusion. Who would give him something so important?

"I can't say this, but the martial arts are real. You can study it yourself! If you have any difficulties or problems, come to me and I will try my best to help you solve them."

"No matter what, I will remember Brother Chai's kindness in my heart."

Since Zhang Xuan was promoted to the crown prince Qianniu, his treatment also increased. His monthly salary and various subsidies increased from ten guan to fifteen guan. At the end of the year, he would not have to spend money on rice, food, accommodation and clothes.

Not only that, his accommodation conditions have also been improved, from the original single room to a private courtyard. With two suites inside and outside, Yang Nai promised him that this courtyard will always belong to him, and even if he is not in the royal palace in the future, he will not let others live in. This is very important to him.

At night, Zhang Xuan carefully looked at his broken pistol and the last two bullets, gently stroked it, and stared at the two shining bullets again and again under the light.

He could no longer carry a pistol with him. If he wants to integrate into this era, he must get rid of his dependence on pistols. He must use a knife, a bow, a spear, and a force to reshape his dignity, which belongs to the dignity of this era.

He was like saying goodbye to his beloved, wrapped the pistol layer by layer with soft silk cloth, and finally put it in a copper box. He put the copper box into a mud hole deep in the corner of the wall, sealed it with soil, and restored several blue bricks to its original position.

He must leave his pistol for the time being, and perhaps one day he will re-drill it and let it play its last two glory, but it is by no means the present.

Zhang Xuan stood and looked at the corner of the wall silently. On the small table beside him, he lay calmly on the bluestone sutra he gave him from Chai Shao. Zhang Xuan's eyes moved away from the corner of the wall and finally fell on the bluestone sutra.

Thanks to the huge land area of ​​the Yan Prince Mansion, each guard has his own room. When the door is closed, the room is his world, so he doesn't have to worry about anyone disturbing him.

Lying on the bed, Zhang Xuan was fumbled carefully about the bluestone slab that could change his destiny. The bluestone slab was as big as a big book of his era. It was very thin, very similar to a tablet computer in later generations. It could be seen that it was carefully polished and the surrounding edges were very round.

There are six pictures engraved on the front of the stone slab. The first four are martial arts practice pictures. They are all naked man waving a heavy hammer in the snow. The difference is the size of the hammer, and there are dense small characters to explain next to it.

Zhang Xuan understood the meaning of these four pictures, which is divided into four stages: forty kilogram hammer, eighty kilogram hammer, one hundred and sixty kilogram hammer, and three hundred and twenty kilogram hammer.

The time required varies from person to person, each time ranging from several months to one or two years. However, Zhang Xuan found that the content between the lines seemed to be specifically targeted at the same person. There is a line at the bottom that is clearly written, "You have any injuries to the tendons and veins on your right arm, which can be made from three pictures. You should not practice the four pictures forcibly, otherwise you will have the worries of life. Remember!"

Zhang Xuan was puzzled, who was he talking about?

At this time, Zhang Xuan felt something. He thought of Chai Shao's words. Someone gave it to him specially. So who would it be? Will there be clues on the bluestone slab?

He closed his eyes and groped carefully in every corner of the bluestone slab.

There is a precept on the bluestone slab, which means that the bluestone sutra is the original object, not re-engraved. Since it is the original, the owner of the bluestone sutra will definitely leave some clues on it.

Sure enough, he found a thin mark in the upper right corner of the bluestone slab, which were two very small Chinese characters. He immediately sat up, reached out to bring the oil lamp over, and looked at the two Chinese characters carefully.

The handwriting is engraved very small and difficult to find, but Zhang Xuan can see it clearly. The two Chinese characters are: "Zhongjian".

Zhang Xuan could not describe the shock he was in his heart at this moment. It turned out that this bluestone sutra was a treasure of Zhang Zhongjian, but.

How did it come to Chai Shao's hands? How could Zhang Zhongjian give it to himself?

But after just a little thought, Zhang Xuan immediately realized that Chai Shao was a member of Wuchuan Prefecture, so this bluestone must be given to him by Wuchuan Prefecture. Why? Do you want him to win over or have other plans? Or is this a deal?

Zhang Xuan's heart was in a mess. He knew very well the preciousness of this bluestone sutra. No matter what purpose Wuchuan Mansion gave it to him, he owed a great favor.

Zhang Xuan temporarily threw away his inner doubts and focused all his energy on the bluestone scripture in his hand. He turned over the stone slab, and the back was the formula of the gluten-free medicine. There were about thirty kinds of medicines, each of which had a detailed portion. The specific method of making it was written very carefully.

Zhang Xuan was already familiar with the practice methods of the Sui Dynasty. Generals of the Sui Dynasty relied heavily on medicine for their practice, so there was a saying that "three-point skill and seven-point skill" that the formula of each practice medicine belonged to the family's top secret and would never be leaked to outsiders. Even Wang Bodang only gave himself ready-made medicine. As for how Peiyuan Dan was refined, he knew nothing.

Zhang Xuan himself was not very familiar with medicinal materials, and the names of the medicines of the Sui Dynasty seemed to be different from those in later generations. He had never heard of most medicinal materials, such as Gui Yuzi, Black Silkworm Head, Kirin Gang, Green Dragon Vein, etc., which made him confused.

It seems that I can only go to the pharmacy tomorrow to ask. Zhang Xuan stood up, quickly walked to the table, spread out a piece of paper, and copied the pill formula carefully.

The next morning, Zhang Xuan took a day off and came to a Pharmaceutical Street in Fengdu City. There were more than a dozen pharmacies, and the street was filled with the strong smell of medicinal materials. He came to Baiweitang, the largest pharmacy shop on the street.

Baiweitang is very large in scale, with two long counters. There are more than a dozen rows of medicine cabinets in each wooden table, each of which is covered with dense small drawers, exactly the same as the traditional Chinese medicine cabinet in Zhang Xuan's era.

Dozens of pharmacies were so busy that they were not touching the ground, and handed the bags of grabbed medicine through the small window to the clinic on the other side.

Sitting beside the wall were more than a dozen medicine children, who were responsible for grinding, decocting and spraying medicine.

"Please help me take a look!"

Zhang Xuan handed the prescription to a pharmacist, "Are there any medicines above here?"

Yaolang gave him a blank look and sneered, "We are one of the three major medicine shops in the Sui Dynasty. If we don't have one here, then there will be no such medicine in the world."

Yaolang took the prescription and glanced quickly, "Everyone, wait!"

He watched Fang Zi turn and leave, but after walking a few steps, he stopped again. He scratched his head in confusion and asked the other person to come forward to see Fang Zi.

Zhang Xuan couldn't help but feel anxious. Is there something wrong with the prescription?

After a moment, the Yaolang walked back and slapped the prescription on the table, "There is something wrong with your prescription!"

"Where?" Zhang Xuan touched his body.

"Look at this medicine!"

Yaolang poked his fingers as thick as a radish, "What is the purple insect jade pupa? Go and ask the person who prescribes the prescription, what is its name?"

Yaolang never said that he didn't have this medicine, but said that the prescription had made the name of the medicine wrong, but the question is, where did Zhang Xuan find the prescription?

He thought for a while and asked, "Are there anything else except this medicine?"

"There are others!"

Zhang Xuan smiled and said, "Then put this medicine first, grab other medicines for me, and grind them into powder carefully."

"Wait!" Yaolang shouted, "I have a big order and prepare to study medicine!"

Zhang Xuan soon learned the meaning of the "big order" that Yaolang said. A pack of medicine powder worth more than three pounds was required, and in the end, he asked him for nearly a hundred stagnant of money. He brought ten taels of gold, and almost all of it was contributed to the pharmacy, and exchanged a pack of medicine weighing three pounds.

It was not until the afternoon that Zhang Xuan returned to the Yan Prince's Mansion. As soon as he entered the mansion, he met Chai Shao head-on.

"Where have you gone? I've looked for you for a whole morning?" Chai Shaoluo asked with a little complaint.
Chapter completed!
