Chapter 350: Heaven-shattering thunder

Wen Tianxiang continued: "Your Majesty, the Ministry of Agriculture has also issued a lot of policies, with the support of the Academy of Sciences and the Ministry of Commerce, these policies encourage farmers to carry out scientific planting in order to increase the yield per mu in various places, at the same time, the policy also encourages the rich labor force to develop handicrafts according to local conditions, in order to increase the income of farmers, the affairs and efficiency of traditional departments such as the Ministry of Officials, the Ministry of Rites, and the Ministry of Industry have been improved to varying degrees. ”

"Okay, there's progress in all departments."

"Yes, Your Majesty." Wen Tianxiang said excitedly, "At the beginning of May, the state-owned commercial bank has been opened in all provinces and roads in our country, and the next step is to prepare to open to the state capitals, and the branches of the Royal Silver Bank, the Independent Commission against Corruption and other branches have also been successfully established in various places. ”

"Very good, two Aiqing, I will be here first tonight, I am a little sleepy, and other matters will be discussed tomorrow and in the morning."

"Yes, Your Majesty, the ministers are retired."

I can finally sleep comfortably in my familiar bed, and after talking with Wen Lu and the two, I am completely clear about the major affairs of the court and government in the past two months, close my eyes, and under the massage of Quan Jiu, I soon entered the dream,

In the afternoon of the next day, accompanied by Yuan Jian and Xiao Qi, I came to Shifeng Commercial Bank.

"I've seen Childe." Yang Hui, Yun Bofei and the other four people who were waiting here said in unison,

"Everyone, sit down."

I looked at the two strangers behind Yang and Yun: "This old man is Mr. Wanyan Tianlei, and the handsome young man is Zhu Shijie." ”

Yang Hui got up and introduced: "Hui Gongzi, exactly, the elder is Mr. Wanyan, the younger one is Zhu Shijie, Zhu Shijie, most of the textbooks of our Lin'an University, of course, also include the textbooks of our Department of Mathematics, and the original author is this Huyan Gongzi." ”

"Son Huyan." Zhu Shijie exclaimed, "Later, Zhu Shijie saw Huyan Gongzi, but I didn't expect that the erudite Huyan Gongzi was so young, when I was reading the mathematics, chemistry, physics and other textbooks of Lin'an University, I always thought that Huyan Gongzi was an elder. ”

I smiled: "Zhu Shijie, what, isn't it like it." ”

Zhu Shijie blushed and said, "No, no, I didn't mean that." ”

"Zhu Shijie, you grew up in the north, you can come to our dynasty to study and live, I welcome you on behalf of Lin'an University, Lin'an University will provide you with the best learning and research environment, I think, whether it is academic atmosphere or research conditions, Lin'an University is second to none in the world today."

"Childe, I already know this."

"Well, Zhu Shijie, you know the Pythagorean theorem."

"Childe, I know."

"Then do you know the projection theorem?"

"Childe, I saw it in a college textbook, and Mr. Yang said that you invented it, Childe."

"Sort of, the purpose of my question is not to boast about yourself, but to hope that you can draw inferences from the Pythagorean theorem, from which a lot of similar theorems can be derived, you are still young, young people, you should be active in thinking, dare to think about what no one dared to think before, and not stick to the rules, in the field of science, you must continue to explore, mathematics is the foundation of all disciplines, don't look at some boring numbers, lines or graphics or something, but if there is no mathematics, then what physics, For example, Mr. Yun and Mr. Wan Yan, you are experts in firearms, so you should know that when throwing objects, it is best to throw them at an angle of about 45 degrees. ”

"Yes, Childe."

"Do you know why?"

Yun Bofei said: "Hui Gongzi, this is the experience of his subordinates in practice. ”

"Well, you may have come to the right conclusion through countless experiments, but if you know the mathematical theory of the projectile, you will quickly come to a conclusion. I continued, "Practice is the only criterion for testing theories, but if we know the theory in advance and have it as a guide, can we get twice the result with half the effort?" ”

Yun Bofei nodded and said, "Childe is high." ”

Most of the ideas of the muskets and artillery developed by Yun Bofei are derived from my own design concepts, and this process can be regarded as practice under the guidance of theory.

"In today's field of mathematics, Mr. Yang Hui can be described as a leader, Zhu Shijie, you learn from Mr. Yang, as long as you work hard, I dare to conclude that within ten years, your achievements will be no less than Mr. Yang, and you will definitely become the pride of my Chinese nation, and you will be famous for centuries."

Although Zhu Shijie didn't know who I was, he knew that most of the natural science textbooks of Lin'an University were made by me, and seeing that Yang Hui and other famous professors of the university respected and respected me so much, he understood that I was not very human, and he was extremely happy to hear my assertion: "Thank you Gongzi for your encouragement, Zhu Shijie will work hard in the future." ”

"Okay, Mr. Yang, Zhu Shijie, you go downstairs to have some tea first, and I will talk to Mr. Yun and Mr. Wanyan for a while, and we will have dinner here later."

"Yes, Childe."

The so-called earth-shaking thunder, is a kind of artillery invented by Wanyan Tianlei in the last years of the Jin Kingdom, it can be said that it is the earliest prototype of artillery, the earth-shaking thunder artillery is filled with gunpowder in an iron can, and the fire is lit, the cannon fires, its sound is like thunder, it can both explode and burn, and it is in the center position, even if it is wearing armor, it will be penetrated, but it is a pity that the national strength of the Jin Kingdom in the last years of the decay, just developed the initial trial product of the earth-shaking thunder, and was destroyed.

"Wanyan Tianlei, your surname is the royal family of the Jin Kingdom."

"Hui Gongzi, Zai Xia is indeed a branch of the royal family of the Jin Kingdom."

I saw that Yan Tianlei was a little nervous, and said with a smile: "Mr. Wanyan, don't mind, I'm just a little curious." ”

Wanyan Tianlei nodded and said, "Childe, I know you must want to ask me why I'm here." ”

"Mr. Wanyan, yes, I do have this question."

"Childe, in the next childhood has been very interested in firearms production, since the sensible, he has devoted himself to the development of firearms, and his ears almost do not hear anything outside the window, so he does not care much about the grievances between the Song, Jin and Mongolia, in the first year of the Jin Kingdom Tianxing, that is, in 1233, the Mongolian Khan Wokotai led the army to attack Bianjing, at that time the Jin State was unable to resist, the north was lost to Mongolia, the south was frustrated by the Song, the land was ruined, the national strength was weakened, and the people's hearts were lost, in the siege war launched by Wokotai, General Wan Yan Cheng put the two trial products of the earth-shaking thunder on the head of the city, under the launch, happened to kill the righteous son of Wo Kotai, after the city was broken, Wan Yan Cheng died in battle, Wo Kotai could not find the person who launched the earth-shaking thunder, so he wanted to take out my anger with the developer of the earth-shaking thunder, when Wo Kotai came to my house in person, I was hiding in the secret room in the backyard, and my father did not have time to dodge, was caught by Wo Kotai, and the Wo Kotai asked my father to hand over the developer of the artillery, my father did not obey, and was killed by Wo Kotai. ”

Speaking of which, Wanyan Tianlei is already in tears,

"Mr. Wanyan, have a cup of tea and talk slowly."

"Yes, Childe." Wanyan Tianlei took a sip of tea and said, "Childe, it's rude to you." ”

"It doesn't matter, the surname of father and son is human nature."

"Childe, since then, in the next hate of the Mongols, after the war stabilized, I came to the Song Dynasty, thinking, can fight with the Mongols in the world is only the Great Song Dynasty, so I pin the hope of revenge on you Song people, however, in the past 30 years, in the Song Dynasty blindly passive defense, with all due respect, the Great Song Dynasty did not have the slightest aggressiveness, and the later Jin State is not much different, just like that, I gradually lost the heart of revenge, only spent my mind on the development of firearms, I also feel that the scenery of the south of the Yangtze River is beautiful, and I have lived in a small village outside Lin'an City for a long time in the name of Yan Tianlei, since last year, I vaguely feel that the atmosphere of the Song Dynasty has changed, although I don't know the details, but I also know that the Great Song Dynasty has changed an emperor, especially since March this year, the imperial court has carried out science and technology month activities, and let the accomplished scientists enjoy the same treatment as officials, which can be said to be unique in history, sighing, I have ignited the revenge that has been buried for many years, but because I am a native of Jin, Therefore, I was afraid that it would be inappropriate, and after thinking about it, I came to Lin'an University on the last day of March. ”

After Yan Tianlei took another sip of tea, and continued: "At that time, I thought, try your luck, I am almost sixty years old, if there is no chance, I will completely die this heart of revenge, in Lin'an University, I met Mr. Shen Yiqiu Shen, I asked him, is there a person who is proficient in firearms, I want to talk to him, I didn't expect Mr. Shen to be very sensitive to firearms, immediately asked me if I understand firearms, I said yes, Mr. Shen asked me a few questions, and immediately asked people to call Mr. Yun, now I can be regarded as meeting a confidant, a chat is all night, Childe, I have always prided myself as the first in the development of firearms, I did not expect that the firearms technology of the Great Song Dynasty was so advanced, I might as well also, Childe, I have two wishes in this life, one is revenge, the other is to develop the most advanced firearms, after talking with Mr. Yun, I told Mr. Yun my identity, Mr. Yun told me that the firearms he developed are largely derived from the guidance of the current emperor, I was shocked, thinking, how can the emperor of the Song Dynasty understand the production of firearms, and listen to Mr. Yun's words, the emperor attaches great importance to talents, Regardless of the background, just like that, I said that I am willing to make a contribution to the production of firearms in the Great Song Dynasty. ”

Yun Bofei said: "Childe, what Mr. Wanyan said is true, and Mr. Wanyan's attainments in firearms are indeed extraordinary, in the past two months, the artillery, musket and projectile technology of our Gunpowder Division have been greatly improved with the help of Mr. Wanyan and Zhao Yuncong. ”

"Okay, Mr. Wanyan, welcome to join the Great Song Dynasty Gunpowder Supervisor, I will let you fulfill your two wishes, in order to show my sincerity, Bo Fei."

"The subordinates are here."

"You tell Mr. Wanyan my true identity."

"Yes, Childe." Yun Bofei said, "Mr. Wanyan, this Huyan prince is the current emperor of my Great Song Dynasty. ”
