Children between the ages of eight and fifteen are easy to expand the meridians and open acupoints because the meridians have not yet been finalized, and it is much easier to wash the meridians and cut the marrow than adults, so the speed of children's martial arts training is much faster than that of adults.

Bai Ziyun bought boys and girls between the ages of eight and fifteen in order to recruit disciples and train martial arts to enrich the strength of his sect.

In the next time, Bai Ziyun was busy with various practices, and most of the daytime was spent on teaching.

Although most of the newly recruited students have entered Confucian colleges, they still have to learn other courses besides Confucianism.

Courses offered at this stage: Confucianism, Mathematics, Martial Arts, Medicine. There are only three teachers: Zheng Xuan, Bai Ziyun, and Yu Ji. (Zhang Bozu and Yu Ji changed shifts and went to Changshan, Jizhou to study the plague)

Zheng Xuan taught Confucianism, but in fact, he mainly taught Mongolian studies, Yu Ji taught basic medicine, and Bai Ziyun taught mathematics and martial arts.

Zheng Xuan is like a treasure for Bai Ziyun's mathematics and Arabic numerals, and often comes to Bai Ziyun to discuss mathematical problems, and the more he comes into contact with Bai Ziyun, the more he feels that this person is unfathomable.

After teaching for a while, Bai Ziyun was also annoyed, and simply handed over the teaching of mathematics and martial arts to Zhou Zhuang. Although Zhuang Zhou was unwilling, his master's order was difficult to disobey, so he could only go to "work" with a sad face.

Bai Ziyun had free time to study the "Tai Chi Zhenjing" and the "Rune Treasure Book", which he had recently redeemed, and his merit value of 3,000 points was rectified, and the content on it was like a dictionary, and all the runes were introduced.

For example, runes are like electronic components on a circuit board, the electronic components form a loop, and the runes form a magic circle, and the magic circle can burst out when it inputs true qi. The magic circle is generally engraved on the soul, because the magic circle engraved on the soul is relatively stable, and the rune can only exert its due effect if it is engraved on the soul.

There are tens of thousands of runes in the "Rune Treasure Book", plus the general understanding of each rune and the principle of the basic magic circle, the number of this book has reached tens of millions of words. Bai Ziyun estimates that with his current learning ability, it will take four or five years, or even longer, to fully master this subject.

Bai Ziyun did things during the day and practiced at night, so that the time passed day by day, and after about ten days, Xu Laojiang ran over and said excitedly: "Shangxian, the cement has been made, please go over and take a look." ”

"Good!" Bai Ziyun was also quite happy, and walked quickly to Baijiazhuang and came to the lime kiln.

There was a bunch of people inside, and there was a pile of gray powder on the ground. Bai Ziyun stepped forward, picked it up with his hand and pinched it, it felt that it was not as delicate as the cement in later generations, but it was already very good to be able to make it look like this in ancient times.

"Shangxian, this cement is like the fairy world?" Old Craftsman Xu asked nervously, but their group of people were busy for nearly ten days before they made this immortal thing, can they not be nervous?

Someone is going to ask, isn't there a detailed process? Why more than ten days?

This is because the ancient tools are too primitive.

The main raw materials for cement are limestone, clay, iron ore and coal, which are common and available in most parts of China. Bai Ziyun found a few mountain people who were familiar with the mountains and asked some questions, but in a few days, he found them all. However, it is very laborious to transport, especially the amount of limestone required is particularly large, and it takes a lot of manpower to carry it from the mountains to the county seat, which is tens or even hundreds of miles.

After the materials arrived, the stones had to be powdered with primitive tools, which was more laborious than carrying limestone, and it was estimated that it would take more than a month to get all the materials right. And in the past ten days, it is just such a small pile of cement now.

It can be seen from this that in ancient times, it was impossible to pave roads on a large scale, except for conscriptions that did not cost wages like the construction of the Great Wall by Qin Shi Huang. In such an environment as the late Han Dynasty, the construction of highway infrastructure was completely a matter of labor and money. Therefore, Bai Ziyun does not plan to promote cement widely.

"Whether it's cement or not just need to be poured with water. Go and bring water, and sand, and gravel, and plaster powder. ”

The craftsmen took all the things, and Bai Ziyun commanded the craftsmen to make the sand, gravel, cement, gypsum powder into a pulp with water according to the proportion, and then made it into a cement slab, flattened it, spread a layer of straw, and told them to water it often.

It took about seven or eight days for the cement to harden, and after Bai Ziyun looked at other projects, he went back. He was very busy now, in addition to instructing craftsmen and teaching students, he also had to develop medicines for the plague.

He just exchanged some prescriptions for effective treatment of plague in traditional Chinese medicine and some prescriptions in Western medicine, and almost spent his merits. Fortunately, according to the medicine made in Zhang Zhongjing's "Treatise on Typhoid Fever", he sent a batch to Changshan County a few days ago, and healed many people, and his merit value began to rise. That Changshan Taishou Peng Feng has greatly promoted this medicine in Changshan County, and now other counties in Jizhou have also heard the news and have sent people to purchase drugs from Baiyun Medical Center. It is foreseeable that the merit value will be greatly increased in the future.

Bai Ziyun saw that curing the plague could greatly increase the merit value, so he spent a lot of energy on refining medicines, but unfortunately there was no glass now, and it was impossible to make chemicals such as glass test tubes, otherwise he could make Western medicines that had a faster effect.

Seven days passed in a flash, and in these seven days, Gao Shun had already arrived at the long stay, and brought dozens of cars to worship the teacher.

Although the Gao family is not as good as the Gongsun family, Jizhou is also quite famous and has assets. This time, the Gao family heard that Gao Shun worshipped Changliu Shangxian as a teacher, and they were all overjoyed, and it took more than ten days to prepare gifts, which can be described as extremely heavy. There are five million dollars in five baht alone, and there are countless other silk medicinal herbs.

Gao Shun also found out that his master did not have a Taoist couple, and the personal maid was only Sanniang, so he bought four virgins at a high price.

Bai Ziyun looked at the four charming and lovely girls, his heart was moved, and he secretly felt that Gao Shun had eyesight, especially the five million money made him happy, and he was short of money, so this disciple sent it.

Seeing Gao Shun like this, Bai Ziyun suddenly had a good impression of this disciple, and gave him gifts in return, such as some daily necessities such as soap and vegetable oil.

The things sent are cheap goods in modern times, Bai Ziyun feels that he is too shabby and quite embarrassed, but he can't come up with good things now, so he often guides Gao Shun in martial arts. But Gao Shun was flattered, especially the master's return gifts, which were priceless treasures, and secretly celebrated that his "investment" did not fail. Wild vegetables and big trees, thank you for the autumn reward!!
