Liu Song Hanque

Chapter 457 He Chengtian

Tai Chi Temple.

The palace of the Ministry of Rites.

From time to time, bursts of laughter came from a dark room where the sun and the moon were not seen all year round, which looked gloomy and weird.

Such a scene obviously shouldn't exist in the solemn six palaces, but everyone else in the Ministry of Rites seemed to be familiar with it.

At this time, an internal official of the palace came to the Ministry of Rites and knew directly that Zheng Xianzhi, the Shangshu of the Ministry of Rites, had explained his intentions to him.

"Your Majesty wants to see He Chengtian?"

Zheng Xianzhi also had a headache, and finally pulled the internal officer to the front of a dark room.

"It's not that the minister disobeyed the imperial decree, it's just that He Chengtian is old and has a strange temper. He has been calculating something these days. If anyone disturbs him, he will really beat them."

The inner officer frowned, and gently pushed open the door in disbelief.

A somewhat decayed smell spread over the surface, and I saw rice paper piled up in the small dark room, with some Tianzhu numbers and symbols densely written on it, and a figure was lying on the ground, hunched over, writing and drawing on the ground.

"He Shilang, Your Majesty has an order to call you into the palace immediately."

The internal officer yelled, but found that He Chengtian hadn't moved at all, so he yelled again at the top of his voice, which made He Chengtian turn his head around.

He Chengtian is also from a family with a good appearance.

It's just that with his unkempt appearance now, it is really impossible to combine him with the status of a member of the court's Ministry of Rites.

"Your Majesty summoned me?"

He Chengtian was taken aback for a moment, and then he cheered up alone: ​​"Coincidentally! I happen to be going to see His Majesty too!"

Then, He Chengtian washed up casually, and followed the inner officer happily to the Liangyi Hall.

"Sir He Chengtian, see Your Majesty! Your Majesty, please be safe!"

"I'm safe."

He Chengtian was ordered to repair the new calendar as early as Liu Yu's time, and Gao Yun was also ordered to leave by the way, so he is no stranger to Liu Yizhen.

But before Liu Yizhen opened his mouth, He Chengtian was the first to tell Liu Yizhen excitedly: "Your Majesty, I have recently made new achievements in the study of the celestial degrees!"

Weekly degrees.

Later generations are also called pi.

Only then did Liu Yizhen realize that He Chengtian was indeed a fierce man, and he calculated pi as 3.1429.

From the perspective of future generations, this number may be a bit off, but in this era, He Chengtian is truly No.1.

What's more, he can be regarded as paving the way for the future Zu Chongzhi.

All science must be systematic.

And the system must be completed by one generation for another.At least Liu Yizhen has never seen the kind of person who can complete the construction of the entire system of the Appearance discipline by himself.

Sure enough, this was what He Chengtian reported to Liu Yizhen, and Liu Yizhen also became interested, pulling Gao Yun, and the three of them sat around to study mathematics.

Wang Xiu, Wang Maide: "..."

The three said it was a discussion, but in fact it was Liu Yizhen who stood in another dimension and crushed the other two.

Fortunately, Gao Yun has always known Liu Yizhen's real strength, and He Chengtian also supported Gao Yun's mention of Liu Yizhen's real strength. From the beginning, he questioned what Liu Yizhen said, and gradually turned into shock, and then he learned humbly until Liu Yizhen started After unintentionally taking out the calculus, the eyes of the two changed to "confused".

Seeing that Liu Yizhen's voice was getting louder and the other two's voices were getting quieter, Wang Xiu hurriedly dragged Liu Yizhen out of the "immersive" lecture.

"Your Majesty! Sailing! Sailing!"

Liu Yizhen just woke up like a dream, and He Chengtian and Gao Yun also retreated from the state of brain shutdown.

Among them, He Chengtian's eyes were even more dull. After a long time, a sentence came out of his mouth: "Your Majesty... are you inhuman?"

As soon as these words came out, several pairs of eyes fixed on him, especially Fan Daoji, who had been on guard all along, almost rushed over to hack He Chengtian to death.

He Chengtian, who came to his senses, quickly explained: "What I mean is...Your Majesty is inhuman, just like a god!"

Only then did everyone's eyes soften, but only Gao Yun and He Chengtian knew that this was not flattery at all.

Others don't understand mathematics.

Only by standing at the pinnacle of mathematics in this era like He Chengtian and Gao Yun can they experience the helplessness and fear in the face of Liu Yizhen.

The things in Liu Yizhen's mind are far away from the reality of this era. Perhaps this is the reason why Liu Yizhen doesn't release all the knowledge he knows.

Unlike the panic of the two, Liu Yizhen was very happy.

After all, it is very difficult for me to confide and discuss with the world happily, and the consequences will be very dire.

Only an extraordinary genius like He Chengtian can barely talk to himself.So don't "persecute" him and Liu Yizhen "persecute" whom?

"I'm looking for He Shilang mainly for the shipping and navigation."

After talking quickly, Liu Yizhen got to the point.

"I know He Shilang is proficient in astronomy and geography, so I want to ask He Shilang to talk about the things needed for shipping."

Shipping?

He Chengtian himself is from Tancheng, Donghai County, and he knows far more about shipping than anyone else present except Liu Yizhen.

"Shipping by sea is actually not difficult. The route pointed out by His Majesty is actually to transport materials from the south to the north along the land and bypass Qingzhou."

"In this way, you don't have to worry too much about supplies and fresh water."

"Only one thing."

He Chengtian was a little worried.

"The sea is the sea after all, and the waves are unpredictable. Once there is a strong wind, the sea will roll up the boat and don't know where to go."

"So, in this shipping, the direction is the top priority!"

After hearing the answer he wanted to hear, Liu Yizhen also expressed his request:

"That's true. I invited He Shilang to come here to solve this problem."

"I also hope that He Shilang can make a star map to solve the urgent need of shipping."

"It's easy!"

He Chengtian responded with a full mouth, for he who has studied astronomy all his life can draw the star map with his eyes closed, but this problem is still not resolved.

"Even if you have a star map, it's hard to guarantee that nothing will go wrong."

The weather cannot be sunny forever, not to mention that the star map needs to be used with another artifact.

"This does not worry He Shilang, as long as he draws the star map, I can solve other things naturally."

He Chengtian saw that the emperor was cheating, and it was hard to break the casserole and ask the end, so he followed Jin Yiwei to the East China Sea to draw a star map.

a few months later.

He Chengtian, who had drawn half of the star map, received the object Liu Yizhen gave him.

"This one is called a compass, it can always point to the north, and it complements the star map."

"Another thing is called a telescope, which can help large ships at sea to observe the surrounding situation."

Taking these two things out alone is a powerful weapon for the country. Together, it can be said that it directly opened the door of Huaxia Shipping.

"This shipping is done!"
