I am the king of the dead

Once there is an earthquake in any direction, Duzhu will fall in that direction.

The invention of this wind and seismograph was naturally made by Xu Dun after consulting ancient books, and he was quite satisfied.

The first person to make a seismograph was Zhang Heng in the Eastern Han Dynasty.

According to history, this seismograph cannot predict earthquakes. It can only record the occurrence of earthquakes when an earthquake erupts in a certain direction, so that the court can respond conveniently.

In the southwestern region where earthquakes occur frequently, it takes [-] days to transmit the news to the capital.

Houfeng Seismic Instruments are recorded in "Qi Zhun" written by Xin Dufang in the Northern Qi Dynasty, and "Earthquake Bronze Instruments" written by Lin Xiaogong in the early Sui Dynasty, and its schema and production method are also passed down.

It is a pity that after the Tang Dynasty, the two books were lost, so what exactly did they look like.

Xu Dun's Houfeng seismograph has been built for more than nine months, but it has never recorded a real earthquake.

In the very beginning, Duzhu, who was standing upside down, never knocked down any tooth machine, and never dropped the copper shot.

This troubled Xu Dun quite a bit. He carefully made the bottom of the column into a circle, and then made the bottom of the column into a semicircle.

Duzhu, who was standing upside down, knocked down the tooth-losing machine for the first time, and the copper pellet fell into the mouth of the toad below.

But soon it was the second, third, and tenth time. Xu Dun gradually discovered that the tooth-removing machine of this seismograph would fall over and smash the tooth-removing machine no matter when people were walking or talking loudly.

Xu Dun almost gave up.

First, because it is too sensitive, and it can't judge what is an earthquake, what is a human movement, even if it stomps or jumps, it will fall if there is a slight movement, and it is impossible to judge whether it is an earthquake.

Secondly, after experiments, it was found that the direction in which the pillars fell was completely random. Standing in the northeast direction and speaking loudly, it fell in the south direction.

His Majesty knew that he was making a seismograph a long time ago, so he had no choice but to report the failure of the production.

He was very unwilling, but he could only come here temporarily.

Originally, this was the product of Qin Tianjian's failure to restore ancient instruments.

But soon, Fang Weimin, an Hanlin from the Hanlin Academy, grabbed his sore foot.

Qin Tianjian has now become a thorn in the side of Confucian scholars, because there is a statue of Mozi standing in the Qili Bureau of Qin Tianjian!

This was established by His Majesty. It's not that Confucian scholars have resisted, and even a major incident happened. However, after the incident of Confucianism's Chaotian Que happened, His Majesty won a complete victory.

This statue dedicated to Mozi and respecting Mozi as the most holy teacher was still erected.

When the news of Qin Tianjian's failure to imitate the ancient Houfeng seismograph spread, the wind suddenly rose!

This time I came prepared.

Several major poetry clubs began to criticize Qin Tianjian for wasting state funds and criticizing Mozi for being useless, and this criticism intensified.

Xu Dun was immediately brought to the forefront.

This Hanlin named Fang Weimin was a Jinshi of the orthodox seven years. He was the most radical one, and a majestic essay was born out of nowhere.

From the historical records, Fang Weimin pointed out the discrepancies in all historical records, and believed that the wind, weather and seismograph did not exist at all, and it could not accurately record the earthquake.

He believes that Zhang Heng really made a seismograph for the weather, because many historical materials have recorded this invention, but there is no evidence to prove it, and there is no reason to convince people that the seismograph has the function of recording earthquakes, and it may have been invented at the beginning. decoration.

In other words, Fang Weimin believed that the Houfeng Seismograph itself was defrauding funds.

Zhang Heng is a big liar!

This narrative system is provocative because it makes sense.

In the Ming Dynasty, there were countless products that cheated funds. For example, the three black dragon cannons could not be fired at all, and many firearms were used to cheat the Ministry of War.

All of a sudden, it sparked a monstrous discussion, and the wave of opposition to Qin Tianjian and the top ten calendar bureaus once again overwhelming.

In the big speculation, this is the norm. Some people want to move forward, while others are holding back.

Life is full of vicissitudes and strange things.

"Your Majesty is here!" A high-pitched voice came, and Xu Dun straightened his clothes and knelt on the ground.

Xu Dun bowed his head and said in a loud voice: "I deserve death for my crimes, and I failed to fulfill your majesty's entrustment."

Zhu Qiyu came here on a horse, dressed in regular clothes quite capable, still full of heroic spirit, he said with a smile: "Be flat, you are not to blame."

Xu Dun fell into a kind of panic. He admired Zhang Heng very much, but he couldn't restore his instrument, and even made Zhang Heng's reputation possibly tainted.

This made Xu Dun feel uneasy for the past half month.

He said loudly that Zhang Heng is not a liar, but he has no proof.

Xu Dun argued: "Your Majesty, the Han, Sui and Tang Dynasties all moved the instrument from this place, saying: "Test it with things, and the agreement is like a god."

"It's not overnight, but for nearly 900 years. There is a lot of agreement. It is impossible for the minister to restore it. However, they...they are too much."

Zhu Qiyu said with a muffled smile: "Are you going to fight with them? Can you fight them?"

"They always do."

"Before this happened, they began to question first, and asked, is this thing useful, can it be used, and is it a waste of national and domestic funds?"

"In fact, I just want to put the money in my own pocket, or simply take money from others, so I talk like this."

"Not surprising at all."

They are always like this, what is it like?

The general routine is to eliminate heroes. As long as heroes can be eliminated, that period of history can be eliminated.

The history is very long, but none of it is superfluous, each one is precious.

In this turmoil, as long as they can confirm that Zhang Heng's Houfeng seismograph is a fake, they can label Zhang Heng as a liar.

Then negate Zhang Heng's various contributions in astronomy, geography, and equipment, and finally wipe out this history of exploration in astronomy, geography, and mechanics.

That's their purpose.

The eradication of a civilization begins with the eradication of heroes and history, and after the eradication of history, it is necessary to attack in an all-round way.

Negating thousands of years of humanistic thought, denying the spiral of the political system, denying all the greatness and legends of this civilization, and ultimately destroying civilization.

Did the Roman civilization die out in Jingtai four years?

No.

In the four years of Jingtai, this civilization called Rome has come to an end.

There are always people who want to bring this civilization of China to an end, and the loudest voices are usually insiders.

They call this questioning, and Zhu Qiyu never opposes questioning, but why can't the bullets fly for a while?

Zhu Qiyu looked at the two seismographs, Qin Tianjian had enough funds, not to mention two, ten or a hundred could be built.

"How do you use this?" Zhu Qiyu asked doubtfully, pointing to the first Houfeng Seismograph.

Xu Dun stepped forward, took the copper dragon ball out of the dragon head, and threw it into the toad's mouth, making a tinkling sound.

"Your Majesty, this is the way to use it. The capital pillar inside will not move at all..." Xu Dun said helplessly.

It's no wonder that the scholastics criticized them verbally and in writing. They did spend money and failed to get things done. Although Daming has money now, it can't be wasted.

The first Houfeng seismograph was an upside-down column with a flat bottom, and the first time it felt a shock, it was crooked and did not fall at all.

Zhu Qiyu looked at the seismograph and finally laughed out loud, it was indeed useless.

He walked to the second seismograph, Xu Dun was standing far away, the first seismograph did not move at all, and the second seismograph was even more speechless.

"How do you use this?" Zhu Qiyu asked again.

Xu Dun took half a step forward, jumped up and down, and then the sound of jingling bells came through.

Zhu Qiyu looked at Xu Dun with a face full of tears and laughter. This second station is really too sensitive.

Xu Dun and His Majesty explained the difficulties.

"In fact, it can be built underground. In this way, won't it be able to prevent the impact of those messy vibrations?" Zhu Qiyu made his first suggestion.

Xu Dun's eyes lit up, indeed, the seismograph, the seismograph, if not placed under the ground, where is the seismograph?

But Xu Dun's eyes quickly darkened.

But this can only solve the first problem, preventing other vibrations from affecting the seismograph.

But this seismograph can't measure the direction at all like it did in history.

Zhu Qiyu looked at the astronomical student of Qin Tianjian, and took out two pillars, showing an expression that really did.

It was exactly as he had guessed.

The ones with flat ground are too stable, and the ones with round bottoms are too unstable.

Zhu Qiyu stood with his hands behind his back, standing in the fierce north wind, and said with a smile: "My dear friend, do you know why the seismograph is called the Houfeng Seismograph?"

"Ah?" Xu Dun was taken aback for a moment, His Majesty seemed to have discovered a blind spot that he hadn't.

Hou Feng, do you want to wait for the wind?

Xu Dun fell into confusion.

Zhu Qiyu said with a smile: "When the wind blows, the first thing to sway is the wind chimes, the lanterns, the meat strips hanging from the beams, and the black beasts on the Tonghui River. They sway with the wind. "

"It's the same when there's an earthquake."

Xu Dun's eyes widened. The black spots on the Tonghui River... His Majesty's thoughts were as strange as ever, but they were so reasonable.

Zhu Qiyu took out a blueprint from his sleeve and said, "So, it's hard to determine whether there is an earthquake with your column, but we can use the hanging spindle pendulum to determine whether there is an earthquake."

Zhu Qiyu's drawing does not have a copper shell outside, it is just a shelf.

It is composed of a spindle-like copper hammer suspended by a copper chain. Once there is an earthquake, it will inevitably swing. At this time, the earthquake and its specific location can be determined.

Xu Dun took the blueprint tremblingly, bowed his head and said, "Your Majesty is wise..."

For the Houfeng Seismograph, the pillar in the middle is not standing, but hanging. This kind of thinking made Xu Dun suddenly enlightened.

Zhu Qiyu said with a smile: "Sometimes, some secrets are hidden in the name, but Fang Weimin and others, they may know it, or they may not know it, so they avoid talking about it."

"As the supervisor of Qin Tianjian, you can't be fooled by them in the future and make yourself uneasy. In fact, if you study for a few more days, you will make it."

"But because of their abuse, you have fallen into the confusion of being me and being me, and being swayed by their words."

"Don't scold them, the wild dog on the street is barking, don't pay attention to it."

Xu Dun bowed his head again and said, "Your Majesty is wise, and I would like to obey the holy instruction."

"Okay, I'm leaving first." Zhu Qiyu patted Xu Dun's arm and said, "Do your job well and don't be influenced by others."

Zhu Qiyu rode away.

Xu Dun immediately started his work, studying the wind seismograph of the spindle pendulum.

Your Majesty, indeed Your Majesty.

This evil wind finally blew up, and Fang Weimin wanted to go to the Qin Tianjian all day long.

It's hard to slap a slap loudly. Qin Tianjian would fight back a few words before, but since His Majesty came down, Qin Tianjian closed the door all day and didn't even fight back.

This time, Fang Weimin was extremely embarrassed, they were shouting, astronomy students, but they ignored them at all.

When the wind was raging, Xu Dun finally opened the door of Qin Tianjian, holding an object half the size of a table, covered it with a red cloth, and headed towards Juxian Pavilion.

Zhu Qiyu is dealing with official business. He has just finished reading the math results of the Imperial Academy and the Imperial Academy.

Calculus scoring is very strict, right is right, wrong is wrong.

"See Your Majesty, is Your Majesty blessed?" Xu Dun bowed his head and saluted. Although he was a little tired, he was quite excited.

Zhu Qiyu nodded and said, "I'm safe, sit down."

Zhu Qiyu read the math scores in his hand, circled the last few names, handed them to Xing'an and said: "These fifty people, each of them will give fifty silver coins. For a year, their math scores have been very good. I am very happy." Congratulations, some money, as a reward."

Whether there is a golden house in the book, Zhu Qiyu does not know.

But Zhu Qiyu can give material rewards of [-] silver coins to students who study mathematics seriously. If they study mathematics well, they really have silver coins.

Zhu Qiyu said with a smile: "Xu Jianzheng, looking at you, does it seem to be related to New Harvest?"

Xu Dun took the plate from the astronomical student next to him, handed it to Xing'an, bowed his head and said, "Your Majesty, inspired by His Majesty, I made it."

Xing'an checked that under the red cloth, it was not gunpowder or other highly poisonous substances, but a bronze vessel, which was placed on the table.

Zhu Qiyu gave him a very sketchy drawing, briefly describing the principle, but Xu Dun also gave him a very delicate object.

Xu Dun pointed to the top ball on the bamboo umbrella and said: "The top Guan ball, when the spindle swings, the Guan ball will slide down the bamboo umbrella."

"This is the eight suspension cables hanging on the cong. The swing of the spindle pendulum will pull the eight suspension cables and drive the cong. Each scale of the cong being pulled indicates the intensity of the earthquake."
