Many people who read books are not interested in science subjects other than Jingyi, after all, these are not examined in the imperial examination, but those who are also interested come by hobby. In the arithmetic class, there were a few from Guozijian; Gewu came to a student, is the youngest son of Chen Yaozhi, the current Ministry of Works, named Chen Qinian, he is more famous in Tokyo, all day long studying utensils, good at designing exquisite things, has improved the bow and crossbow, so that its range has increased by two percent, more proud people, Meng Ming handed him a physics textbook for the second year of junior high school, he regarded Meng Ming as a celestial, took the book and studied it. Tokyo Meritorious Gao Family, Gao Wenhuan's younger brother Gao Wenli, was interested in agriculture, so he came here despite his family's opposition, Meng Ming arranged him in the biology department, gave the junior high school version of biology, and was also fascinated.

The controversy over the university hall has been continuous, and some Confucians have scoffed at Xinxue as heresy, secretly calling it the school of lowly servitude, and are ready to boycott it in tandem. Of course, he didn't know that Meng Ming was now being questioned by Kou Zhun in the political affairs hall. For the construction of the official road from Tokyo to Nanyang, the imperial court reached an agreement and prepared to build it, and Meng Ming had the most say in the construction of the official road, so listen to Meng Ming's opinion. Meng Ming wrote a booklet about the quality requirements of the official road, including the mixing of concrete, the speed of hardening, and the maintenance of the pavement, especially the precautions are quite detailed. The construction of the official road began to be open to bidding, and many began to bid for it. The Cao family has a large construction team, undertaking the construction of bridges, mansions, roads, and official offices, and is the most powerful, and his family wants to undertake this project exclusively, but Kou Zhun is not allowed, and finally makes a decision on three construction businesses, including the Cao family, who are responsible for building three hundred miles.

Cao Ning has been running to Meng Ming's house for the past few days, it is the problem of cement supply, Meng Ming finally thought of a way, build a lime kiln every fifty miles, and burn cement on site, which can save transportation capacity and save time. In the end, Meng Ming sent people to build six cement kilns in half a month; The other two heard the news and also came to negotiate, because the cement Meng Ming was the only one, which belonged to the monopoly, according to the above method, he decided to build three cement kilns for each of the two, and finally built a total of twelve cement kilns. Therefore, the road will be repaired in October, and it will be repaired for a trial basis, and it will not be repaired for half a month at most.

On the second day of October, Meng Ming was invited by Zhang Huaizheng, the priest of Guozi, to give a lecture on Guozijian, Meng Ming gave a morning of lectures, first of all, pinyin, and then arithmetic. When he walked into the classroom, he saw that it was full of people, both inmates and professors. Meng Ming will be pinyin one by one, because they are all adults, this is not difficult, Meng Ming finished speaking, everyone mastered, he picked up the "Great Song Dictionary" and talked about it. Finally, everyone asked questions, and Meng Ming answered them one by one. Finally, a young prisoner asked: "Sir, how to write these classics that are used by future generations in the present and Ze, is it not the favor of God, or the stars of Wenqu descend to earth", seeing that this prisoner is a witty person, his words caused everyone to laugh.

As soon as Meng Ming raised his hand, everyone calmed down. He said: "I have never felt wiser than others, I feel that our brains or thoughts are accustomed to listening to others, but not thinking ourselves, the sage once said: It is better to believe in books than to have no books." I'm just thinking a little more than you do. The sage also said: Threesomes must have my teacher. My dictionary is borrowed from Guangyun, plus my method. The times are progressing and developing, from slash-and-burn farming to quyuan ploughing, from no writing, knotted rope notes, to the glorious and prosperous chapter of the literature and propaganda, which is inseparable from the wisdom of generation after generation of sages, but knowledge is increasing, we stand on the back of the sage to see the world, we will see higher and farther, rather than standing on his toes and looking up. Because many scholars and even some Confucianists believe that there is an immutable truth in the world, and the truth is understood by the "sage" from the heart. When the saints knew the truth, they preached it to the common people. Therefore, the truth in the scriptures can be "pushed to the four seas and passed on to all generations". This view, which experience tells us, is not applicable to the new era that is changing with each passing day. I say that there is no one-size-fits-all truth. ”

Meng Ming said another sentence that he had given to Kou Zhun before: "What I pursue is to learn from things, apply what I have learned, integrate knowledge with action, and practice with oneself, which is also the purpose of my founding of this university." After Meng Ming finished speaking, everyone fell into deep thought. I think what I am saying will inevitably cause upheaval in the world of thought.

Suddenly, a voice sounded angrily: "A bunch of nonsense, heresy, disgusted. Then an old scholar stood up and rebuked him. Meng Ming was very calm, because he knew that new ideas and ideas would inevitably be resisted by the old forces, and even wanted to get rid of them quickly. In the end, more than a dozen people were also echoing, and Meng Ming debated with them. Meng Ming was on the sidelines again, calmly responding, and fighting the Confucianism. The old pedant, who finally argued, was speechless, and finally fainted. Meng Ming pointed directly at the weakness of these pseudo-scholars, making people realize their hypocrisy.

Meng Ming didn't care, and continued to talk about arithmetic, and talked about multiplication and division. Ten Arabic numerals from 0 to 9 were introduced, as well as four calculation symbols of "+", "-", "+", and "÷". Most of the inmates admired Meng Ming's knowledge. Finally, he taught the method of measuring the number of acres and measuring the height of the tower, which was used to prove Meng Ming's idea of applying what he had learned.

After a morning of lectures, Meng Ming conveyed his Meng philosophy to these prisoners, which was a good opportunity for the scholar class to hear the doctrine of "unity of knowledge and action, and practice with oneself", and cut a hole in the old thinking, so that new ideas and new doctrines could be brought in. This is just the beginning, Meng Ming's road is still very long, and there is a long way to go.

These theories of Meng Ming also aroused the thinking of some enlightened people, because Meng Ming relied on the name of Neo-Confucianism and also quoted some Confucian classics, so it did not cause widespread resistance from the scholar class.
