Chai Shao's dormitory in the palace was better than that of the average guard, and he had a separate small courtyard with a tall locust tree in the courtyard, which was in the middle of spring, and the locust tree was leafy, and the pavilion covered the house.

The dormitory is divided into two rooms, the inner is the dormitory, and the outer room is the study and living area.

"My brother's dormitory is good, better than mine!" Zhang Xuan looked at the old locust tree above his head and smiled.

He also just moved, and like Chai Shao, he also has two rooms, inside and outside, but the yard is empty and lacks a big tree.

"If you like, let's change the dormitory, you can't imagine the trouble caused by this big tree, every morning the black finch is noisy, sometimes I want to pick up an axe and cut it."

"Forget it! Sichang kept it for himself, I'm just talking. ”

The two talked and laughed and entered the room, 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!" It took a lot of effort for me to get it. ”

Chai Shao did not fully follow Dou Qing's instructions, Dou Qing asked him to give the bluestone scripture to Zhang Xuan in a roundabout way, but Chai Shao wanted this favor.

"It's—"

Zhang Xuan took the box, only felt heavy, felt at least three or four catties heavy, he opened the box, inside was a cyan slate, smooth as jade, engraved with patterns and words, and then look closely, it turned out to be a method of practice.

"Don't ask me where I got it from, I just tell you that this kind of exercise is called the Qingshi Sutra, which can be practiced the method of cohesion the day after tomorrow, which is very suitable for you, and some people have achieved three breakthroughs by practicing this kind of exercise."

Zhang Xuan gently stroked this smooth slate, and his heart was full of emotion, he knew the value of this bluestone slab.

It has been a month since he entered the Yan Palace, and he originally hoped to learn the clever method of cohesion in the King of Yan, but he gradually realized that the method of cohesion is only passed down from generation to generation between father and son, and will not be taught to outsiders at all, and it is very difficult to practice this method of cohesion.

His determination to practice martial arts had already wavered a little, but since he got Luo Shixin's Overlord Marksmanship, he really understood the importance of the method of cohesion.

Overlord marksmanship requires not only great strength, but also unpredictable speed, and the basis of speed lies in strength, from extremely slow to extremely fast, from halfway acceleration to halfway deceleration, all of which are inseparable from the adjustment of power.

Without the method of cohesion as a foundation, he couldn't practice Luo Shixin's overlord marksmanship at all, and just when he was at a loss, Chai Shao gave him a vital method of cohesion, how could this not make Zhang Xuan grateful.

He knows that this kind of exercise can be encountered but not sought, especially the exercises that can be practiced the day after tomorrow, which are extremely precious, and there may only be a few in the world.

"Brother Chai's great kindness, the younger brother has received it, and I will report it later!"

Chai Shao was also a little ashamed in his heart, patted Zhang Xuan's shoulder and smiled: "You don't have to thank me so much, this is actually someone specially gave it to you, and I just handed it over on my behalf." ”

"Who is it?" Jang Hyun asked suspiciously, who would give himself such an important thing?

"I can't say this, but the exercises are true, you can study them yourself! If you have any difficulties or problems, just come to me and I will try my best to help you solve them. ”

"Anyway, Brother Chai's kindness, the younger brother will remember it."

．．．．．．．．．．

Since Zhang Xuan was promoted to the crown prince Qianniu, his treatment has also improved, and his monthly allowance has increased from ten to fifteen, and at the end of the year, there is still 300 stone of rice, and he does not need to spend money on food, lodging and clothing.

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

At night, Jang Hyun carefully examined his disassembled pistol and the last two bullets, gently stroked it, and stared at the two shining bullets again and again under the lamp.

He can't carry a pistol with him anymore, if he wants to integrate into this era, he must get rid of his dependence on a pistol, he must use a knife, a bow and arrow, a spear, and strength to reshape his dignity, the dignity of this era.

As if bidding farewell to his beloved, he wrapped the pistol in layers of soft silk cloth, and finally put it in a copper box, which he placed in a deep mud hole in the corner, sealed it with earth, and restored a few green bricks to their original places.

He had to get rid of his pistol for a while, and maybe one day, he would dig it up again and let it play its last two glory, but not now.

Zhang Xuan stood up, silently staring at the corner of the wall, on the small table beside him, lying calmly the bluestone scripture he gave him from Chai Shao, Zhang Xuan's gaze moved away from the corner, and finally fell on the bluestone scripture.

Thanks to the huge size of the Yanwang Mansion, each guard has his own separate room, close the door, the room is his world, he doesn't have to worry about anyone to disturb him.

Lying on the bed, Zhang Xuan carefully groped for this bluestone slab that could change his fate, the bluestone slab was the size of a big book of his time, very thin, much like a tablet computer in later generations, it can be seen that it is carefully polished, and the surrounding edges are very rounded.

The front of the stone slab is engraved with six pictures, the first four are pictures of martial arts, all of which are of a naked man wielding a heavy hammer in the snow, the difference is the size of the hammer, and there are dense small characters next to it.

Zhang Xuan understood the meaning of these four pictures, that is, they are divided into four stages, forty catties hammer, eighty catties hammer, one hundred and sixty catties hammer, and three hundred and twenty catties hammer.

The time required varies from person to person, ranging from a few months to a year or two each time, but Zhang Xuan found that the content between the lines seemed to be specifically for the same person, and there was a line at the bottom that was clearly written, 'If you have an injury to the tendons and veins of your right arm, you can make it into three pictures, and you can't force four pictures, otherwise you will have lifelong disability, remember!'" ’

Zhang Xuan was puzzled, who was this talking about?

At this time, Zhang Xuan felt something, he thought of Chai Shao's words, this was specially given to him by someone, so who could it be, and will there be clues on the bluestone slab?

He closed his eyes and groped around the bluestone slab.

There is a precept on the bluestone slab, which means that the bluestone scripture is the original, not re-engraved, since it is the original, then the owner of the bluestone scripture will definitely leave a little clue on it.

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

The handwriting is very small and not easy to find, but Zhang Xuan can see it clearly, and the two Chinese characters are: 'Zhongjian'.

Zhang Xuan couldn't describe the shock in his heart at this time, it turned out that this bluestone scripture was Zhang Zhongjian's collection, but ..... How did it end up in Chai Shao's hands? How could Zhang Zhongjian give it to himself?

But after only thinking about it, Zhang Xuan immediately realized that Chai Shao was a member of Wuchuan Mansion, so this piece of bluestone must be given to him by Wuchuan Mansion, why? Woo yourself, or do you have another plan? Or maybe it's a deal.

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

Zhang Xuan temporarily threw away the doubts in his heart, and concentrated all his energy on the bluestone scripture in his hand, he turned over the stone slab, and the back was the formula of the Yijin drug, there were about 30 kinds of medicines, each flavor has a detailed amount, and the specific preparation method was written very carefully.

Zhang Xuan is already familiar with the practice methods of the Sui Dynasty, and the generals of the Sui Dynasty are extremely dependent on drugs for their practice, so there is a saying of 'three points of work, seven points of medicine', and the formula of each practice drug belongs to the top secret of the family, and it will never be leaked to outsiders, even Wang Bodang only gives himself ready-made medicine, as for how Pei Yuan Dan is refined, he knows nothing.

Zhang Xuan himself is not very familiar with medicinal materials, and the names of the medicines of the Sui Dynasty seem to be different from those of later generations, and most of the medicinal materials he has never heard of at all, such as ghost jade seeds, black silkworm heads, unicorn horns, green dragon veins, etc., he is confused.

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

．．．．．．．

Early the next morning, Zhang Xuan took a day off and came to the street of Fengdu Pharmacy, where there were more than a dozen pharmacies, and the street was filled with a strong smell of medicinal herbs.

Baiweitang is very large, with two long counters, and more than a dozen rows of medicine cabinets on each side of the wooden table, each filled with dense small drawers, exactly the same as the Chinese medicine pharmacies of Zhang Xuan's time.

Dozens of medicine men were so busy that they didn't touch the ground, handing bags of medicine from the small window to the clinic on the other side.

At the wall sat a dozen medicine boys, who were in charge of grinding, decocting and concocting the powder.

"Please help me take a look!"

Zhang Xuan handed the prescription to a medicine man, "Do you have all the medicines here?" ”

Yao Lang glanced at him, and sneered continuously: "We are one of the three major medicine shops in Da Sui, if we don't have it here, then there will be no such medicine in the world." ”

Yao Lang took the prescription and quickly glanced at it, "It's all there, wait a minute!" ”

He watched Fang Zi turn around and leave, but just after taking a few steps, he stopped again, only to see him scratching his head in confusion and calling another person to come forward to see Fang Zi.

Zhang Xuan's heart couldn't help but hang, could there be something wrong with the prescription?

After a while, Yao Lang walked back and slapped the prescription on the table, "There is something wrong with your prescription!" ”

"Where?" Jang Hyun stepped forward.

"Look at this medicine!"

Yao Lang poked heavily with his fingers as thick as small radish, "What is a purple insect jade chrysalis?" You go and ask the person who opened the prescription, what is its name? ”

Yao Lang never said that he didn't have this medicine, but said that the person who prescribed the prescription got the name of the medicine wrong, but the question is, where did Zhang Xuan find the person who prescribed the prescription?

He thought for a moment and asked, "Is there anything else besides this flavored medicine?" ”

"Everything!"

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

"Wait a minute!" Yao Lang shouted, "A big order has arrived, ready to research medicine!" ”

Zhang Xuan soon knew the meaning of Yaolang's 'big order', a pack of more than three catties of medicinal powder, and finally asked him for nearly 100 yuan, he brought ten taels of gold, almost all of which were contributed to the pharmacy, in exchange for a large package of medicine weighing three catties.

It wasn't until the afternoon that Zhang Xuan returned to Yanwang's mansion, and as soon as he entered the mansion gate, he met Chai Shao head-on.

"Where have you been, I have been looking for you all morning?" Chai Shao asked with a little complaint.
