Daqin Fusu: It is difficult to start the battle

Chapter 162

"What I'm going to tell you today is called 'triangulation'..."

Fusu sat on the emperor's throne, and hundreds of ministers with high crowns sat in groups below.

At the forefront is the white and fat Zhang Cang, in stark contrast to the black and thin public transportation rail.

Then, there are some Shixia Shi, and Dushuichang, Dushuicheng and other officials in charge of water conservancy affairs in various counties and counties.

Fusu gestured twice in the air with his hands, and said loudly: "The basic principle of the so-called triangulation method is that a triangle is stable, and any three sides can only form one kind of triangle!"

"Thus I can determine the length of the other two sides according to the length of one side of the triangle and the size of the two interior angles."

"The specific method is to select two points first, the distance between these two points can be accurately measured, and then measure the angle of the same distant object at the two points, and calculate the difference between the angle and the distance between these two points, which is the baseline. The distance is calculated using trigonometric formulas."

Zhang Cang and the others gestured twice on the ground, nodded in a vague way, feeling like returning to the school life of their teenage years, remembering the fear of being dominated by calculations.

Although they didn't understand what the trigonometric function Fusu was talking about, Fusu had long been prepared for this.

He directly drew a trigonometric function table and sent it down, letting them compare it with himself.

In fact, as long as you have a caliper with a slightly higher accuracy, and then put the fixed-length side at several hundred angles, and then measure the length of the three sides, it is stupid, but very practical.

What Fusu said today was mainly for the water chief and the officials under his jurisdiction.

Dushuichang is an official office under the Shaofu.

To wear a crown must bear its weight.

The benefits of the mountains, rivers and rivers belonged to the emperor, so the money for the management of the mountains, rivers and rivers was naturally allocated from the emperor's private funds.

However, Fusu summoned the public transport rail today, and he had another purpose.

That is, he wanted to make a simple theodolite.

With this thing, a more accurate map can be drawn.

Whether it is building roads or digging ditches, it can come in handy.

Therefore, although the public transportation rail below tried his best to listen to Fusu's narration, he couldn't control his eyes and looked at the pile of blueprints placed on the other side of his body.

On the cover at the top of the drawing, there is a line of large characters written in official script, theodolite vernier.

……

About two miles away from the west gate of Xianyang Palace, there is a narrow street. At the end of the street is a series of old-looking houses.

In stark contrast to the old houses, there is a row of carriages side by side on the square in front of the houses, decorated luxuriously, and most of the curtains of the carriages are made of brocades of every inch of cloth and gold.

As for the rough horse used to pull the cart, there is no trace of hair on the whole body, and it looks extraordinary, even in the stables of the palace, it is a rare good horse!
This is the school in Xianyang City.

According to the rules, only the direct sons of officials with high ranks and above a thousand stones in the Neishi area are recruited.

In other words, all the students studying here are the top second generation of Qin.

Hou Feng rode on his thin horse and walked slowly from the alley.

The wealthy servant guarding outside the school looked contemptuously at Hou Feng's skinny dark-haired horse, but then his eyes moved up, and when he saw the Xiezhi crown on Hou Feng's head and the ribbon on his waist symbolizing a thousand-stone high official, He fell to his knees involuntarily, resting his head on the ground.

Hou Feng ignored them, tied the horse and went straight up the steps, and gently knocked on the door of the school room with some peeling paint.

The door opened, and after checking that his identity was correct, he walked into the entrance room led by two waiters.

Although Hou Feng had famous people in his ancestors, and he himself studied under Han Fei, he did not come from a school, in other words, he did not come from a major, but relied on his own true skills...

Well, it was mainly because of Fusu's appreciation that he was able to become a senior official of Qianshi.

This was the first time he entered Qin State's classroom, and he found that the inside of the classroom was the same as the outside, simple and dilapidated.

The sound of reading in the classroom is also the laws and regulations that he is familiar with.

Take the law as the teaching and officials as the teacher.

This is a teaching philosophy that legalists have always respected, and it can cultivate a large number of qualified legal officials to implement the rule of law.

That's why Hou Feng came to the classroom today.

That day, after he talked with Fusu about the "magic power" he had learned in his chest, the next day he was appointed as Tingwei Youcheng in the imperial edict, with a rank ratio of [-] stones and a black ribbon on the bronze seal.

At the end of the imperial edict, Fusu did not ask him to take office in Tingwei's Mansion, but asked him to select one hundred seventeen or eighteen-year-old students from the schools of the internal history counties who were proficient in the six arts of Legalism (similar to the six arts of Confucianism) ) students.

In the edict, these students are called "Xiuyilang", with a rank ratio of two hundred stones. After the emperor Fajia returns to Xianyang, he will go east out of Hangu with him to monitor the world!

But now, he still has more than 20 embroidered clothes left.

In fact, according to Hou Feng's idea, he wanted to directly select Xiu Yilang from the officials in the surrounding government offices in Xianyang. After all, these people are well-informed and convenient for work.

But Fusu directly rejected his idea, and made it clear in the imperial edict that what Xiuyilang needs is someone who dares to fight hard, forges ahead, and is more eager to make contributions than officials.

As Hou Feng walked inward, he pondered a word that Fusu had mentioned in the edict, Second Second...

……

"Student Qin Yannian, [-] out of [-], fined with ten sticks, wash toilet for one month!"

"Student Bai Wuji, hit all nine arrows!"

"Student..."

Below the stands, a young man in a black robe, dressed as the Duke of Qin, was pushed down on the spot by two strong men, stripped off his coat and started beating him.

On the other side, a burly middle-aged man dressed as a wife had a mournful face.

The law of the classroom, the students miss the target, and the teacher in charge of teaching will be fined two grades.

Therefore, this strong man is obviously the teacher of the rookie.

Hou Feng snickered from the sidelines. Fortunately, he was from a poor family and couldn't get into the school, otherwise...

The laws enacted by Shang Jun are not only ruthless to Guishou, but even more ruthless to clean up the nobles!
Soon, more than 100 students passed the selection of physical fitness courses such as shooting and fencing, and successfully entered the interview session.

Hou Feng nodded secretly, thinking that it is no wonder that His Majesty said that he is poor in culture and rich in martial arts. The students in Xianyang Academy are indeed much better than students in other counties in terms of martial arts.

He took out a roll of bamboo paper from the bamboo tube held by the attendant behind him, first bowed respectfully and then carefully opened it.

In the bamboo paper are the test questions compiled by Fusu for the selection of embroidered men, which are actually a hundred multiple-choice questions made according to Qin Law.

Nine out of ten are the top, and they are selected as the embroidered clothes man.

ps: Thanks to 'Knowing the King' for the monthly pass and the reward! (`) than heart
