This traveler only wants to choose the lowest difficulty

Chapter 272 Free Labor

Liang Shu happily followed Wang Dong back home, and the Wang family was not surprised to see Wang Dong bring a friend back. Yang even came out to meet Liang Shu and arranged for someone to set up the dinner Be generous.

During the banquet, Liang Shu couldn't wait to ask about the acceleration of gravity. Wang Dong explained a few times. When Liang Shu thought about it carefully, Wang Dong also asked Liang Shu about his master Li Chunfeng.

Only after Liang Shu's introduction did Wang Dong know that Li Chunfeng's true identity is different from the fortune-telling in historical legends. Although he has a lot of research on various spells, his job is the most famous One of the mathematicians.

Eight years ago, Li Chunfeng, who was only 25 years old, wrote a letter pointing out that there were more than a dozen unreasonable points in the newly revised calendar of the Tang Dynasty, which was appreciated by Li Shimin, so he joined the Taishi Bureau to preside over the calendar revision work. .

From Liang Shu's words, Wang Dong also knew that although Li Chunfeng was not a high-ranking person, but because people were generally superstitious at this time, and Li Chunfeng was the most famous magician in the world, his influence in the Tang Dynasty was absolutely absolute. It is at the top level, even Li Shimin would sometimes ask Li Chunfeng about things he was hesitant about.Wang Dong nodded, because he didn't know why the system thought he should solve Li Chunfeng's disciple, but since the system gave him a task, Wang Dong could also imagine that Liang Shu might be able to help him with some things in the future.

After deciding to follow the system tasks and instruct Liang Shunong on the principles of mathematics, Wang Dong acted immediately.

Then after half an hour he started to have a headache... After answering a new question from Liang Shu, Wang Dong covered his head and shook his head. There is a reason why Liang Shu became a top student. After learning that Wang Dong was willing to teach him, Liang Shu happily asked a lot of questions, and the calculation was really fast. Wang Dong originally thought that he could solve one of his problems, and Liang Shu could calculate it for a long time. I could let him take a break, but I didn't expect that Liang Shu had already solved the related problem within a few minutes after I answered a question, and then threw the next math problem over.

While these problems involve no more than high school math, they also involve gravitation, curve equations, and logarithms.

It is very simple for future generations to pick up these things individually, but for Liang Shu, these things are all novel and incomparable gadgets. It would take several hours to talk about each item thoroughly.
After Wang Dong finished his meal, he started to make up lessons for Liang Shu, and then lasted until about ten o'clock in the later life, Wang Dong finally couldn't take it anymore.

He found an excuse and ran back to the room, then rummaged through the storage ring and found a copy of "Integral Monism" written by Li Shanlan in the Qing Dynasty.

This thing and the geometry translated by Li Shanlan were originally mathematical enlightenment works prepared by Wang Dong. Although these mathematical theories written in classical Chinese made Wang Dong very difficult to read, he was one of the most famous mathematicians in the late Qing Dynasty. Li Shanlan's various translations and annotations of the mathematical theories at that time are very reliable. If they are placed in the eyes of ancient people with a heart, relying on these two books will definitely allow them to master at least modern standards of mathematical knowledge, and The special forms of classical Chinese and thread-bound books would not be too obtrusive in ancient times, so whenever Wang Dong went to the time and space of ancient China to perform missions, he would bring these two books with him to keep in this time and space after the mission. The world of time and space.

Wang Dong took out these two books and threw them directly to Liang Shu for Liang Shu to study by himself.

In the next few days, Wang Dong continued to teach these students every day, sometimes in the school grounds in the city, and sometimes went to the catapults outside the city for practical training. Liang Shu was really overjoyed after getting the two books of Li Shanlan. Studying without sleeping and eating, only occasionally ask Wang Dong some questions that he still doesn't understand after reading. He is usually very quiet. The only change is that the dark circles visible to the naked eye have increased. After staying up late for half a month, he also seems to have early baldness. signs.

After the training of the student soldiers lasted for half a month, Wang Dong returned the group of people to Hou Junji.

Hou Junji personally went to the trebuchet outside the city and saw that every student was proficient in using artillery sights and sights to calibrate the shooting elements, and then accurately hit the wooden fence less than five square meters away within two or three shots. Overjoyed, his affection for Wang Dong deepened.

Afterwards, Hou Junji happily took the students back home. Regarding Wang Dong's reward, Hou Junji hadn't thought about it yet, but he was not in a hurry, because after confirming that the trebuchet would become one of the main battle equipment of the Tang army Afterwards, Wang Dong will continue to train more military craftsmen so that they can master the skills of quickly manufacturing trebuchets on the battlefield, and the various artillery sights they need for these learned soldiers will also be under Wang Dong's guidance. Therefore, Wang Dong's task has not been completed yet, and Hou Junji can wait until Wang Dong has completed all his achievements before rewarding him.

After this group of student soldiers left, Liang Shu stayed on. For some reason, he got his position to Zhechong Mansion in Shanzhou, where he was under the subordinate of Wang Dong, the left general, and began to follow Wang Dong. run.

Wang Dong lamented in his heart that a Guozijian student like Liang Shu is really good at handling things in Chang'an, and he can be transferred if he wants to, which is much tougher than his own background.At the same time, Hou Junji didn't care about it. After all, Liang Shu, a student, couldn't do anything in his military chief yamen, and the reason why he felt indifferent was that so many people were sent this time. Come to study, those cadet soldiers who don't know a lot of characters have already learned how to use artillery sights and sights to aim and fire, but Liang Shu didn't let him play at all, obviously he didn't take it seriously during the learning process, What is the use of such a person staying in his own marching chief yamen?Since he wants to go to Wang Hui's place and Wang Hui is willing to accept it, then let them play by themselves."

After training this group of student soldiers, Wang Dong temporarily put aside his business and went to his farm.

It took Wang Dong a month to build the trebuchet, plus more than half a month to train the cadet soldiers, and a lot of things have accumulated in his farm outside the city.

At this time, Liang Shu probably had basically figured out the two monographs written by Li Shanlan, and he also started to go out for activities, so he followed Wang Dong and started running.

Wang Dong lied to him that Li Shanlan was one of his masters on Kunlun Mountain, so Liang Shu now respects Wang Dong quite a lot.

Originally, when he entered Wang Dong's farm, Liang Shu wanted to help him manage chores, but soon he was attracted by Wang Dong's various planting skills.

At this time, most people who like to study mathematics like Liang Shu have a strong interest in various things in nature.Pay attention to observation by yourself, plus you have money and leisure, and you have enough time for research. If you accumulate time and time, you can be more than half a naturalist.

And Liang Shu also has a lot of research on the planting of various plants and simple botany, so when he saw Wang Dong start to top the tobacco, and then instruct the slaves in the farm to top-dress the tobacco and sugar beets, he revealed Very obvious curiosity.

Wang Dong thought of the system tasks, and he had a good impression of Liang Shu, so he told him about the top advantages of plants, and the junior high school biological knowledge such as the phototaxis of various plants. I benefited a lot from the speech, and from the next day, I brought a small notebook with a brush and was ready to record Wang Dong's words at any time.
