The height agreed by the emperor was ninety-five steps, that is, ninety-five meters, representing the ninety-five supreme; In modern society, building a 95-meter-high building is also a 30-story building, and qualified construction units can undertake the construction, Ye Jinyu has seen a two-story house with 30 floors, from the excavation of the foundation to the completion of the decoration, it takes about a year. If you only build a tower that does not need water and electricity lines, you only need to have a tower with a tube and stairs; Yip believes that time can be shortened.

But that is in modern society, the extremely fast construction speed is because there are a large number of mechanical equipment to save manpower and material resources, and there are many building materials factories in the back; In Datang, it can only rely on manpower, and this kind of climbing to nearly 100 meters is already a huge project.

"Fifteen years is too long." Only two or three months have passed since I wrote a book of more than 500,000 words, and if I want to write it for 15 years, I will not have to prepare tens of millions of words. Ye Jinyu shook his head and said, "Is there no other way?" In the book I brought, did you mention building a house with reinforced concrete? ”

"Yes!" Sun Xin nodded hurriedly: "There are many secrets in the book of the gods of His Highness, which many craftsmen think are secrets, and the cement factory has been mentioned many times, but the ministers have read all the books, but there is no method of cement preparation; The courtiers cry out. ”

That is to say, it is mentioned in the book that a house is built with reinforced concrete, but what this cement is is is not explained; Not to mention how to make it.

During this time, Sun Xin had always memorized the orders of his Royal Highness, read the book hard, and then taught the craftsmen in the Godman's Workshop as much as possible the techniques mentioned in the book, such as iron smelting and steelmaking, muskets and artillery, sextant clocks, ploughs and harrows, and so on. It's just that the time for King Shenxiao to bring the books is not long, he can only swallow the dates and read them, although he has learned a lot from them, he has more doubts. This cement is one of them.

"Well, I've made a note of it, and when I get back, I'll find you some way to make cement; Find more work for the ceramic craftsmen in the god's workshop, and with cement, it will be convenient to build a house. However, thinking of the dust of the cement factory in the county, Ye Jinyu advised: "However, this cement factory should be far away from residential areas, especially away from Shenren Fang; It is best to build it outside the city. ”

The task of building a cement plant was determined, and the burden on his body was heavy, but Sun Xin was willing.

Struck while the iron was hot, Sun Xin reported again: "Your Highness, the minister takes the legend in the book as a test, and the blacksmith in the workshop imitates a cannon......"

Before he finished speaking, Boss Ye, who was taken aback, shouted in surprise: "Artillery? You're saying you made the blacksmith copy the cannon? Where is it? ”

It is recorded in the history books of gunpowder that it is a product of the Tang Dynasty, although the gunpowder of the Tang Dynasty is only the most primitive gunpowder with many other ingredients, but it also shows that the Tang Dynasty was capable of producing gunpowder; However, gunpowder weapons did not come out until the Song Dynasty; Cannons will only appear in the Yuan and Ming dynasties. And now, the long history of the early years of the Tang Dynasty told himself that he had imitated an artillery!

"Let's go, take me to see the artillery you made!" Ye Jinyu couldn't wait, he couldn't even take care of the circuit board, and wanted to go and see Tang Artillery.

But Sun Xin smiled bitterly and explained: "Your Highness, Your Majesty has issued an edict saying that the weapons of my God's Workshop cannot be used in the city; This cannon was built outside the city of Chang'an, and if you want to go to investigate, it will take several hours to go back and forth. It's not early today, go at this time, and you won't be able to enter the city at night. ”

Ye Jinyu was not afraid, and said: "I have a motorcycle!" ”

Speaking of which, the brand-new Lifan motorcycle followed him to Datang, and he was urinated on the first time, and then he rarely used it.

The divine chariot of the King of God comes and goes like the wind, which is well known; Of course, no matter how much it comes and goes like the wind, it is only running on the ground, which is far less shocking than the spaceship, so the most famous of the godmen's means of transportation is the spaceship.

However, Sun Xin has never ridden a motorcycle, and his interest in a car that can run on two wheels without reversing is very high; It's just that today really isn't the time.

"Your Royal Highness, the governor of the Qin Palace, sent a generous gift, saying that it was a gift from the prince to worship the teacher; The minister did not know how to reply. "In this era, accepting apprentices is a big deal, and the head of Sun Xin District, Shi Ke, doesn't dare to be the lord of the Shenxiao King.

It is expected that after the fifteenth day of the first lunar month, Li Shimin will set out on the expedition, and in order to avoid long nights and dreams, he wants to complete the apprenticeship in a few days. As soon as the front foot went back, the back foot was shackled; Those who are bound are also salted and jerky; Of course, the prince of the Qin Wangfu couldn't send salted dried meat, so Li Shimin favored Ye Shenren and sent a batch of books and exercises, as well as a number of gold, silver and jewelry.

How can there be so much attention to such a thing as accepting primary school students, Ye Jinyu said: "Apprenticeship is apprenticeship, let him be free one day, just send it over." He can eat one bite less. ”

Seeing that Ye Shenren said so casually, Sun Xin hurriedly persuaded: "No, no, No, Your Highness, the prince of heaven and earth; For disciples, the teacher and the king are in the same column; "Learning Notes" has a cloud: all the way to learn, it is difficult to be a strict teacher. Shi Yan, then Dao Zun; Daozun, and then the people know and respect. The prince of Qin is apprenticed, An Neng is so sloppy! ”

The ancients often said: One day is a teacher, and a lifetime is a father; Teachers in ancient times not only had the responsibility to educate students to become talents, but also shouldered the responsibility of teaching students to seek careers and careers; Even connections, resources, Taoism, and inheritance can be inherited by disciples.

It turned out that it was so troublesome to accept apprentices, Ye Jinyu couldn't help but regret it, he knew that this was the case, so he didn't agree to Li Shimin.

Ye Jinyu scratched his head, he didn't understand these rules himself, so he could only hand them over to the palace governor: "Sun Changshi, these etiquettes, you watch and deal with them, just teach me how to do it then." ”

"Obey orders!" Sun Xin hurriedly responded, he could see that his Royal Highness didn't know anything about this kind of thing; Such a person who doesn't respect his teacher doesn't know how to learn a skill.

"Okay, tell me what the artillery is!" was interrupted by Li Chengqian's matter, and Ye Jinyu was not in the mood to look at the artillery, so he asked about the situation first.

Seeing that His Royal Highness's interest in artillery was much higher than that of accepting apprentices, not to mention that he couldn't get by, Sun Xin said: "Your Highness, the ministers have been making artillery for a long time, and they are first cast with pig iron as contained in the book, but the pig iron is brittle and unsuitable; Later, it was changed to copper, so that it could be a door. It is four centimeters long and ten centimeters wide; One pound of charge, one blow can send more than 1,000 metric steps. ”

The process of ironmaking is not good, the iron quality is not good, and the ductility of copper is much better. According to what the book says, Sun Xin lengthened and thickened a copper cannon, with a caliber of 100 millimeters, loaded with a pound of gunpowder, which can hit a projectile a kilometer away.

Although it is very primitive, it is a real artillery, at least, this is the artillery made by the Tang people themselves based on the research of the data, unlike the bamboo electromagnetic cannon made by themselves, which is useless.

It's a pity, I'd like to take a look right away!

Ye Jinyu sighed, and then thought of a question, Mom, the spaceship has lifted off, and the artillery has come out again, and with the artillery, the spacecraft has a long-range attack weapon; There is no need to fly above other people's heads to throw mines like the current spaceships. The era of cannons and giant ships is coming, which is the prelude to the beginning of the Age of Discovery...... No, the era of big aviation is correct.

"The artillery has succeeded, does the emperor know about this?" Boss Ye had already drawn a cannon pie in front of Li Yuan.

Sun Xin nodded and said: "Your Majesty came to the test artillery field in person, saw the power of the artillery, and issued an edict on the spot to correct the name of the artillery: General Shenwei!" Read the latest chapters, stay tuned
