As for simplifying numbers, of course, it is necessary to have the legendary Arabic numerals invented by Tianzhu. Zhou Shixiong was not interested in these two countries, but he still did not dare to claim that they were invented by himself. He honestly introduced the word "Tianzhu" for everyone to understand. A hard pen can speed up writing speed, and Tianzhu's numbers simplify their gestures, which everyone who learns them likes very much.

Zhou Shixiong only taught the formulas of addition, subtraction, multiplication and division, and abacus. Of course, abacus is a common style of five in modern times. I talked about algebra a little, and Zhou Shixiong doesn’t remember the one-counter equation. Then there is geometry. Zhou Shixiong is good at this. He was in junior high school for three years, and he could get seven or eighty-tenths by just listening to the class. If he did exercises of more than ninety, it would be certain.

The impact of geometry on craftsmen was beyond Zhou Shixiong's expectations. These craftsmen from apprentices to masters have always learned to teach by oral and deeds by doing this, and if they don't do this, they will be wrong. After learning geometry, they understood why and also asked a lot of why. Some Zhou Shixiong could barely answer, while others didn't know how to answer.

Physics is also very easy to teach, and various mechanics foundations are to teach people to discover science in daily life. Zhou Shixiong used the sled car to explain the friction force, and the two sleds of the sled car to lift the front and back were also answered. Then there were lever and pulley sets. After learning this lesson, several craftsmen took out a set of pulley sets that night and easily lifted Zhou Shixiong's treasure car on the boat.

"Young Master, do these people want to steal your treasure?" Zhu Ying always said appropriate words at inappropriate times. The bosses of the boat watching on the side immediately changed their faces. Zhou Shixiong smiled and patted Zhu Ying's head, "I am the imperial envoy. Whoever dares to steal my things is really not even a surname!"

"Young master, I have heard that you don't want your life. What does it mean to not have your surname?" Li Zhenhe came over curiously, squeezed away the former princess, and declared her sovereignty.

"Why will this surname come after killing the nine clans?" Zhou Shixiong's words made several ship bosses unable to stand up, and their legs were weak and their bodies trembled, as if Zhou Shixiong was reading the imperial edict to them for killing the nine clans.

Chemistry classes are really difficult to do in this era. Just talking about the theory is basically impossible to explain. If you don’t believe it, you can’t help. Zhou Shixiong did two experiments, one was to prove that there is a combustion-enhancing gas in the air, and the other was to obtain crystalline salt with saturated salt. The first combustion experiment is easy to understand after all. This is something that happened around you, and everyone didn’t pay attention to it. The second was lively. The salt eaten by the Ming Dynasty was boiled salt, with a small amount of mineral salt, but it was amazing that you could obtain salt with saturated salt, and the naturally crystallized salt was whiter, which was even whiter than the high-priced green salt.

Zhou Shixiong found that several girls' attitudes towards him changed significantly, and was so scared that he didn't dare to teach chemistry anymore. He just focused on teaching geometric physics. As basic physics gradually deepened, iron horns appeared, convex lenses and concave lenses appeared. If Zhou Shixiong hadn't had many transparent crystals in his treasure, these two things would have been impossible.

The most amazing thing is that the two masters actually made a saw machine. Although it was a small saw machine with the same model, and its power was also man-powered hand-cranked, the four craftsmen's eyes were really vain. This was the result after they learned that the small power shaft drove the large transmission shaft, and it also meant that the trees in the Ming Dynasty would be ruthlessly cut down. Zhou Shixiong could say very proudly, "Cheer, the era of great pollution is coming!" I don't know what is worth cheering for in this kind of mess.

The fleet arrived in Xinning County, Huguang on February 1st of the first year of Chongzhen. Zhou Shixiong was about to get off the boat here and go to Quanzhou, Guilin Prefecture, Guangxi by land. He had already received the imperial envoy flags there and was collecting ships so that the imperial envoy could go downstream. Wang Zunde, who had just made a mistake, dared not act like a governor and personally planned this matter, so that Ma San, who took the imperial envoy flags to find him, enjoyed the treatment of an imperial envoy.

It took two days to get from Xinning to Quanzhou. Zhou Shixiong gave Gong Dajiang a task, using Huanghuali wood to make a wooden strip of two fingers wide and half fingers thick and four feet long. Huanghuali is known as one of the hardest woods, and a group of carpenters failed to complete Zhou Shixiong's task even though they went to Quanzhou.

"Transfer this piece of wood to my room tonight." Zhou Shixiong had seen the tortured wood and had no choice but to decide to do it yourself to make a living.

After dinner in the evening, Zhou Shixiong drove Li Jie and Yueqing out of the room and told them to guard the door and not let people come in. "Chip, estimate how much robots it takes to cut wood." Zhou Shixiong told the chip his request, and then pressed the wood placed on the ground to wait for the result.

"Using less than 100 robots will lose all losses, ten thousand robots will lose ten, and ten thousand robots will lose no losses." Zhou Shixiong was stunned when he heard the chip report. What is the reason? "How could this happen?"

"The amount of workload that the unit bears determines the lifespan of ** unit." This sentence is a bit memorable. Zhou Shixiong thought for a while before he realized that it was just that one person was too tiring to work, and it would be better for two people to share it. Will it be easy for ten people to work together?

"Then let's do it." Since it was free of losses, Zhou Shixiong was relieved and ordered the construction to start. A few minutes later, six yellow rosewood rulers appeared. Just like the rulers that Zhou Shixiong had seen, one side was a rice ruler and the other was a market ruler. Except for the amazing weight, there was no other difference. If these six rulers appeared in 2000 AD, except for the expensive price, everyone would say that they would say that using such good wood as rulers must be burned with more money.

The six straight rulers that appeared in the Ming Dynasty were of great significance. First, the length was accurately divided, the second was to establish the basic unit of length, and the third was to use decimal system, which simplified the conversion method.

As the deputy envoy of the Guangxi Chengxuan General Office, Pan Yinglong made a mistake in the issue of bandit suppression, so he naturally lost the power of the commander-in-chief and was suspended from office in Guilin Prefecture. As the governor, Wang Zunde could not go to Quanzhou to pay homage to Zhou Shixiong, even if he was surrendered, he could not go to Quanzhou to pay homage to Zhou Shixiong. Pan Yinglong, a waste, happened to have nothing to do, and Wang Zunde captured him and asked him to come to Quanzhou to run errands.

"Master Zhou, Governor is waiting for Master Zhou in Guilin. Please Master Zhou get on the boat." Of course, the big man had to be the last to show his dignity. With the help of pulleys and cranes, hundreds of cars quickly completed the loading of the ship, which made Pan Yinglong stunned. After docking the boat specially for the imperial envoy to take for a while, Pan Yinglong remembered to welcome the imperial envoy to board the boat.

"I heard that Xunzhou Prefecture is very fierce. Governor Wang is busy with official duties, so I won't disturb him. After Governor Wang succeeds in suppressing bandits, I will go to congratulate Governor Wang." Zhou Shixiong's idea was very considerate. Although he, the imperial envoy, had no power to interfere in local government affairs, the imperial envoy was the imperial envoy. When he arrived at the local area, he dared to treat him as a passerby. Wang Zunde is busy suppressing bandits now, so he must have no time to accompany the imperial envoy. If he makes a joke, the imperial envoy will directly lead the matter to the emperor, and Wang Zunde cries.

"This is not very good." Pan Yinglong's idea was different from Zhou Shixiong. He always made mistakes when he caught him last time and was kicked home to attend the event by Wang Zunde. If Wang Zunde also made trouble for him, he would be much less guilty.

"I have made up my mind, so Lord Pan doesn't need to say much, just make up." There is nothing to be polite to people like Pan Yinglong who are not good at making things better. Zhou Shixiong shook his sleeves and went up the stairs, without even the intention of inviting the same boat.

From Quanzhou to Xunzhou Prefecture, you can go through the four places of Xing'an County, Linchuan County, Fucheng Linguicheng, and Yongfu County. Then you can enter the three places of Luorong County, Xiangzhou and Wuxuan to reach Xunzhou Prefecture. Even if the road is smooth, it will take as fast as 800 miles of water to reach the fastest of six days. When the fleet passed Linguicheng, Zhou Shixiong sent Li Fusheng to the city to express his gratitude to Wang Zunde, and he would not trouble him by entering the city. As for what Wang Zunde thought, Zhou Shixiong didn't care at all.

The day after boarding the boat, Zhou Shixiong took out six rulers and explained the definition of each scale in the craftsmen's amazing eyes. "These two rulers are archived as standard tools, and you can divide the remaining four."

"Sir Xie." A craftsman knelt down and kowtowed, then held the rice ruler with both hands, crying happily as if he had obtained a treasure.

"If you want to cry back and cry, isn't it embarrassing to cry like this?" Zhou Shixiong was very satisfied with this result. It's normal for vanity to be honest.

"Sir, the imperial envoy also needs such a ruler. Just keep one file, give me the other one." Zhou Shixiong did not expect that the former great scholar Li Fusheng was also jealous of the ruler and was stolen before he could react. The remaining ruler was closely protected by several girls under the greed of everyone's eyes. Shimazu Nan and Zhu Ying were already holding the handle of the knife in their hands and preparing to attack at any time.

Guan Chongguang also wanted a handful. He thought it would be useful to use this ruler to draw maps. However, Zhu Baoer, a good disciple who has been very respectful to him since childhood, did not give him any face. He stared at the teacher's actions and had already classified him into the category of dangerous enemies in his heart.

Several girls retreated smoothly under the heavy siege they thought, protecting the last ruler and fled back to the cabin. As a concubine, You Min did not go to the vestibule, and saw several girls coming back happily and asked strangely, "What's going on? What's the matter? What's the matter so happy?" The seven girls wanted to tell her what happened, but You Min only heard the seven starlings chirping, and the content was not heard at all.

"Since I have learned how to make pulleys with a ruler, I will give you a task to make a bed crossbow that uses pulleys." Zhou Shixiong saw a military bed crossbow on the boat, and thought to let these craftsmen improve it. As for how much it can be done, Zhou Shixiong didn't dare to think about it, so he just hoped that these few people could bring him some surprises.

ps: Roll around and ask for red votes. Brothers with votes should not be too ruthless, just one or two hundred. Also, please ask for the cover. Some people say that my cover is very powerful, but I don’t know whether it is true or false.
