Zhou Buyi was just ten years old at this time.

A young man of this age is so sharp that he doesn't know how to hide his clumsiness.

Zhou Buyi in history followed Liu Xian to Xudu, and later became friends with another prodigy, Cao Chong. Cao Cao even intended to marry his daughter to Zhou Buyi.

Unfortunately, in the thirteenth year of Jian'an, Cao Chong died of a serious illness. Cao Cao's mentality changed drastically and he no longer had any intention of recruiting Zhou Buji.

What happened next was tragic. Zhou Buyi was killed by Cao Cao's men, and the young prodigy withered away.

In Wei Shi's previous life, he was very moved by Zhou Buji's life experience. This time, Zhou Buji took the initiative to come to visit, which was a great opportunity to connect with him and change his destiny.

"Mr. Wei Fu, I have the audacity to come here this time. I really have something to ask of you. I have no doubt that you can come over quickly. Don't you want to find out what happened about the shuttle loom?"

Liu Xian met Wei Shi, and after a brief greeting, he immediately told him his purpose of coming.

Zhou Buyi has a young mind and is very interested in studying things he doesn't understand. He has only seen the actual shuttle loom once in Mijia's weaving workshop. Seeing the shuttle automatically returning, Zhou Buyi became eager to learn and ask questions.

Already.

However, although there was a loom in the Mi family weaving workshop, no one could explain the specific principle of how it works. In the end, it was Liu Xian who asked Mi Zhu and found out that it was something invented by Wei Shi.

"No doubt, if you want to know the principle of the shuttle going back and forth, of course you can, but before that, you answer me a question first."

"When I was in Yingchuan County, I heard that Cao Chong, the son of Cao Sikong, was known as a child prodigy, and there was a story about an elephant being carried on a ship and weighed by carving. Now there is also an elephant that needs to be weighed, but the method of carving cannot be used.

,Excuse me, is there any other good way?"

Wei Shi became curious and decided to give Zhou Buyi a test to see who was better between him and Cao Chong.

Zhou Bujiu thought for a while and said with a rather confident face: "What's so difficult about this? I think there are at least two ways to weigh the weight of an image."

"The first is the lever method. It is recorded in the "Mo Jing" that equal-arm levers can be weighed. We can make a very long and strong wooden pole, with an elephant on one end and a stone on the other end. When the two ends are balanced

, through the weight of the stone, the weight of the elephant can be measured.

"The second is the overflow method. Fill a pool with water, then drive the elephant into the pool, wait for the water to overflow, and then drive the elephant out. The weight of the overflowed water is measured in this way, which is the weight of the elephant."

Wei Shi looked at Zhou Buyi, who was talking in general terms, and the doubts in his heart finally dissipated.

It was quite difficult for Zhou Buyi to come up with the leverage method and the overflow method when he was suddenly asked.

Of course, there are still many ways to actually weigh images under the conditions of later generations.

But under the scientific and technological conditions of the Han Dynasty, apart from Cao Chong's method, the two mentioned by Zhou Buyi were indeed more feasible methods.

"Shizong, your nephew is indeed very smart. The principle of shuttle weaving is actually not complicated. Let me explain it in detail..."

"No doubt, I built two blast furnaces in Shangyong and Neixiang respectively for forging iron stone and gold stone. Do you know what the boiling point of molten iron in the blast furnace is? And what is the secret to making steel?"

Wei Shi was talking about scientific knowledge while making gestures to Zhou Buyi.

The saying of a child prodigy lies in having a clearer understanding of the essential principles of things than others.

Wei Shi hoped that through his story, he could arouse Zhou Buji's interest and then change the outcome of his murder.

"Master Wei, I heard that you have opened martial arts schools in Shangyong and Fangling. I would like to transfer from Xiangyang Academy to Fangling martial arts school. Is it feasible?"

Liu Xian saw that Zhou Buyi was attracted by Wei Shi's question and was reluctant to leave, so he could only sigh and said.

"Of course. If Liu Biejia is worried, you can come together." Wei Shi laughed loudly, and was very happy that he successfully persuaded Zhou Buyi.

His main purpose of coming to Xiangyang this time was to make friends and lay a solid foundation for the future development of Dongsan County.

Therefore, if a future pillar like Zhou Buyi can be caught before Cao Cao does, it will be a victory.

In the following days, Wei Shi and Han Qiang, under the introduction of Sima Hui and Kuai Qi, met with many hermits and famous people near Xiangyang. Among them was Pang Degong, who compared Sima Hui to a water mirror.

Kuai Qi and Pang Shanmin married Zhuge Liang's eldest sister and second sister respectively, which were equivalent to brothers-in-law. With this relationship, Pang Degong agreed to meet them.

Otherwise, Wei Shi was a junior, and Pang Degong would not necessarily see him.

According to Pang Shanmin, a few days before Wei Shi came, the emperor's uncle Liu Bei had come twice in a row.

Compared with Liu Bei, who came diligently but only brought a small gift, Wei Shi, although it was a rare visit, asked Kuai Qi to prepare a generous gift.

Woven linen, forged iron tools, and small pieces of nugget gold from Junshan. These were all rare things, which made the people of Pangshan very happy when they saw them.

In fact, Wei Shi has no immediate plans to send the Pang family to Dongsan County.

Mr. Pang De is definitely not willing to serve as an official, so if he is invited, it will be in vain.

Fengchu and Pang Tong went to Jiangdong again and were not in Nanjun, so they couldn't make friends if they wanted to.

The Pang family will have to wait until Pang Degong dies of illness before they can truly serve as officials. By then, the younger generations of the Pang family will naturally think of who is more suitable to join.

March of the eighth year of Jian'an.

Just passed by in a hurry.

Wei Shi originally wanted to stay in Xiangyang for a while to see if he could make a few more useful talents.

According to the ideal outcome of this trip to Xiangyang, it would be best to meet Zhuge Liang or Pang Tong.

But at this time, an urgent letter sent from Fangling forced Wei Shi to interrupt his leisure life of traveling in Xiangyang.

Liang Xing, a Xiliang general in the Lantian area of ​​Guanzhong, joined forces with Liu Xiong, a Nanshan bandit, and each gathered thousands of people to occupy the Aoguan and Wuguan crossings. They blocked the trade routes and intercepted and killed merchants. They were very arrogant.

Liang Xing also announced that he would sacrifice Wei Shi's head to Sikong Cao Cao just like he killed Li Jue.

Originally, the Shangluo Mountain area belonged to Liao Hua. With the Yellow Turban bandit around, Liu Xiong and his like did not dare to go south to plunder. But now, Liao Hua was adapted by Wei Shi and stationed in the Shangyong area, which gave Liang and Liu two

Opportunity to control Wuguan Dao.

"Master Fu, although Guanzhong is dilapidated, it is a land of three auxiliaries with huge development potential. If Liang Xing and Liu Xiong are allowed to block the Juewu Pass Road, the three eastern counties will only rely on the Han River trade route, and it will be difficult to support them.

"

"The best strategy now is to send troops northward and defeat the Liang and Liu thieves."

In the letter to Wei Shi, Wei Yan, Liao Hua, Lou Gui and others who stayed in the three counties all had a strong desire to send troops to attack the bandits. Liao Hua even took the initiative to ask for help and asked to bring his own troops to pioneer the army.

"Sir, please stay in Xiangyang and try to spend some time with Wolong and Fengchu. Shi will return to Fangling immediately to plan the expedition against the Nanshan bandits. If Shi's prediction is correct, Cao Sikong will probably go south to conquer Jingzhou again."

Wei Shi shook his head helplessly and said to Sima Hui.

It is very difficult to defend the area of ​​​​the Three Counties and Four Battles in the East. The threat from the Guanzhong bandits is not much smaller than that of Zhang Lu.

In addition, Wei Shi remembered that in the eighth year of Jian'an, Cao Cao had conquered Liu Biao in the south before going north to attack Yuan Yuan. There are no historical records of the details of this battle.
