Online Games: Start as an Emperor

After the other party left, Lu Yan came to the Golden Platform again.

I hope luck comes more violently.

Lu Yan placed ten thousand taels of gold on the golden platform and waited quietly.

This golden platform has absorbed an unknown amount of gold. It is a miraculous building in itself. Now that it has recruited many talents, it has become even more magical.

You can see that on the golden stage, the golden ceiling is in full bloom, and in the golden light, the talents of the human race are constantly flashing.

These talents run the gamut.

As long as it's famous, whether it's in history, in novels, or in culture.

All appeared.

Of course, the monsters in mythology have not appeared yet.

Lu Yan didn't ask too much.

In the golden light, there are scholars with feather fans and turbans, counselors with hands on their backs, civil servants with thousands of books in their chests, warriors in armor, commanders riding horses, generals who are not afraid of death, and craftsmanship. craftsmen and so on.

Lu Yan also saw someone playing a candy man.

This is also considered a craftsman.

At this moment, a golden light rose from the ground.

The entire golden platform shines with a thousand-foot-high light. This light is very soft and not dazzling.

Let everyone swim in the golden ocean.

The momentum is huge.

Lu Yan didn't know if it was because he saw the candy blower just now, but Lu Yan's heart skipped a beat.

What if we recruit a candy-playing grandmaster?

Lu Yan suddenly became nervous.

Keep praying.

This is ten thousand taels of gold.

If we really recruit someone who is similar to a sugar blower, kneading soil, making candied haws, etc., that would be really...······

Lu Yan can regret to death

······

At this time, a man appeared in the golden light pillar.

This man is a young man.

He was wearing clothes that looked like official robes.

With patterns.

He was holding a wooden object in his hand. It had a strange shape. Lu Yan didn't recognize it.

"Who is this?" Lu Yan looked at the other party closely.

At this moment, a huge artifact appeared behind the other party.

This artifact had eight directions. They were east, south, west, north, and southeast. , southwest, northeast, northwest, each direction has a dragon head with a dragon ball in its mouth, and under each dragon head there is a toad corresponding to it.

""Seismograph". When he saw this thing, something suddenly appeared in Lu Yan's mind.

This object was none other than the famous seismograph.

"So······"Lu Yan looked at the man in front of him, and his heart suddenly beat loudly.

If the guess is correct, this person should be Zhang Heng, the scientific sage in Chinese history.

One of the most famous scientists since Lu Ban.

Lu Yan guessed correctly. After the seismograph appeared, words appeared around the man, Science Saint - Zhang Heng.

This person is none other than Zhang Heng, one of the most famous scientists in Chinese history.

Zhang Heng, courtesy name Pingzi, was an outstanding astronomer, mathematician, inventor, geographer, and writer in the Eastern Han Dynasty. He was the grandson of Zhang Kan, the prefect of Shu County.

He was born in Xiaolian and served successively as doctor, Taishi Ling, Shizhong and Hejian. Due to illness in his later years, he entered the court and served as minister.

Yonghe died in the fourth year of his reign at the age of sixty-two.

In the Northern Song Dynasty, he was awarded the title of Bo of Xi'e County.

Zhang Heng's astronomical works include"Lingxian" and"Annotations on the Armillary Sphere"; his mathematical works include"Suan Wang Lun"; his literary works are represented by"Er Jing Fu" and"Guitian Fu", etc., together with Sima Xiangru, Yang Xiong, Ban Gu is also known as"the four great masters of Han Fu"."《Sui Shu Jing Ji Zhi contains 14 volumes of"Zhang Heng Collection", which have been lost. Ming Dynasty scholar Zhang Pu compiled"Zhang Hejian Collection".

Zhang Heng made outstanding contributions to the development of Chinese astronomy, mechanical technology, and seismology. He invented the armillary sphere and the seismometer. He was one of the representatives of the armillary theory in the middle of the Eastern Han Dynasty. Later generations hailed him as the"Science Saint" because of his contributions. Outstandingly, the United Nations Astronomical Organization named a crater on the back of the moon"Zhang Heng Crater", and the 1802 asteroid in the solar system was named"Zhang Heng Star".

In order to commemorate Zhang Heng, later generations built the Zhang Heng Museum in Nanyang.

Zhang Heng's work, the seismometer, has not been able to be imitated until now.

Very powerful.

During the Eastern Han Dynasty of the Han Dynasty when Zhang Heng lived, earthquakes were relatively frequent.

According to the Records of the Five Elements in the Book of the Later Han Dynasty, a total of twenty-six major earthquakes occurred in the more than thirty years from the fourth year of Yongyuan of Emperor He to the fourth year of Yanguang of Emperor An. Earthquake zones sometimes span dozens of counties, causing landslides, house collapses, and river flooding, causing huge losses.

Zhang Heng has a lot of personal experience with earthquakes.

In order to grasp the national earthquake trends, he finally invented the Houfeng seismometer, the world's first seismograph, in the first year of Yangjia after years of research.

At that time, this instrument was used to successfully predict an earthquake in the western region, which attracted national attention.

This is more than 1,700 years earlier than Western countries using instruments to record earthquakes.

In the eleventh month of Renyin's third year in Yangjia, Emperor Shun of the Han Dynasty, a dragon machine of the seismometer suddenly activated and spit out a copper ball, which fell into the toad's mouth.

At that time, people in the capital felt no sign of the earthquake, so some people began to talk about it, wondering why the seismometer was not working.

Within a few days, someone from Longxi rushed to report and confirmed that an earthquake had indeed occurred there a few days ago, so people began to be extremely convinced of Zhang Heng's superb skills.

Longxi is more than a thousand miles away from Luoyang, and the seismometer's markings are correct, indicating that its seismic measurement sensitivity is relatively high.

However, due to the long history, Zhang Heng's seismometer has been lost, leaving no physical objects or drawings, only some brief written records.
