When Zhang Jian learned that his master was coming, he quickly ran out of Laboratory 101 to greet him. There was also a man in his twenties who came out with him. Although the two looked very different, their temperaments were very similar, and they were very calm and restrained.

He is Zhang Jian’s brother-in-law, Wang Yingxuan, a private school teacher from Shaanxi.

Although Zhao Hao spent a lot of effort to get Wang Xiucai from Shaanxi for his unborn son Wang Zheng, Wang Xiucai was proficient in arithmetic, astronomy, mechanical geography, and science.

This is not surprising, because it was under the guidance of Zhang Jian, who developed a strong interest in mechanical physics under the guidance of his brother-in-law.

For such outstanding talents, Zhao Hao naturally could not just keep the breeding, but also let him shine and heat up. He hired him as the director of the Iron and Steel Research Institute of 01 with a high salary.

"Hello, Brother Wang." Zhao Hao smiled and knelt down from his disciple, and then called his brother-in-law his brother-in-law.

Wang Yingxuan wore a pair of thick myopia glasses, which was matched after coming to Jiangnan. Back then, he was too serious to study because his myopia was too serious. Unexpectedly, a small pair of slacks could cure the chronic disease that ruined his future.

After putting on glasses, he actually wanted to continue studying. After all, he was only in his early twenties, so it would be no problem to take the exam for a juren in Shaanxi.

But the old Qin of Qianlong was grateful for his kindness, and Wang Yingxuan said nothing nonsense and plunged into the mountains of Chenjiawu.

Zhao Hao likes such honest people who are easy to bully and is very polite to him.

It was just that his brother-in-law's master called him elder brother, which made Wang Xiucai, who paid great attention to ethics, feel uncomfortable. However, he is loyal and obeys others' jobs, and he will not say much.

"Brother Wang, is there any movement in my sister-in-law's stomach?" Zhao Hao's next words almost made him lose his power.

"Cough cough cough!" Wang Xiucai's face turned red, and he shook his head awkwardly, "No."

"Try harder." Zhao Hao smiled and said, "Try to have more children, and you must have branches and leaves in the south of the Yangtze River."

"Hey, hey..." Wang Yingxuan nodded in confusion. He couldn't figure it out even if he wanted to break his head. Why did he ask himself if he had a wife every time he met?

Fortunately, at this time, Xing Yunlu, the director of Institute 02, also heard the news, and his junior brother Qu Rukui hurriedly came out of the 201 laboratory to pay homage to the teacher.

Xing Yunlu was a student brought by Zhao Hao from Beijing. This astronomer who had not yet grown up showed a strong interest in science. Zhao Hao was really short of staff, so he asked him to come to the center's Mineral Research Institute for a few years.

As for Qu Rukui, everyone must be even more unfamiliar with it, because they had never mentioned it before... It is true that Mr. Zhao's stall is getting bigger and bigger now.

You can't do it one by one, no matter how big or small.

It's not something that needs to be forced to be temporarily... serious face.

The Qu family is a large family in Changshu. Qu Rukui's father Qu Jingchun was the second-place winner of Huiyuan in the 23rd year of Jiajing. He was the chief official of the "Yongle Encyclopedia". He served as the left minister of the Ministry of Rites and a Hanlin scholar. However, he had retired due to illness and returned to his hometown to live in seclusion.

Qu Rukui is the second son of Qu Jingchun. He is nineteen years old this year and is studying at Suzhou Prefecture. Unfortunately, he was poisoned by Li Jiaozun and deceived... Oh no, I introduced him to Kunshan and became a teacher to learn science.

And I am very honored to be promoted from a fifth-level scientific student to a fourth-level "registered disciple" with Xing Yunlu. You can call Mr. Zhao the kind of master.

Given Zhao's snobbery, he is willing to accept disciples in an extraordinary way, of course, because this person is like Xing Yunlu, and has extraordinary features.

In another time and space, this young master with many names and strokes was a noble man after Matteo Ricci came to the Ming Dynasty. He guided Matteo Ricci, who was fooled to be ordained as a monk, put on a Confucian robe, studied Confucian classics, and dealed with scholars and officials. This time, Master Renli's missionary career took a turn.

He was also the first scholar-official to be fascinated by Western learning in the Ming Dynasty. Everything that Matteo Ricci said had a great attraction to him. He followed Matteo Ricci diligently for a year and then learned mathematics, sphere geometry, and the first volume of "The Origin of Geometry".

I also learned how to make various sundials, how to measure height and distance, and by the way I learned Italian…

These were all learned in a year, and they were definitely an absolute genius.

Unfortunately, he later damaged his reputation due to emotional disputes and suddenly lived away from the world. From then on, he disappeared and did not leave a famous name in the history of science like Xu Guangqi and Wang Zheng.

Zhao Hao was eager for scientific geniuses, and even the underage Xu Guangqi did not let go, let alone the adult Qu Rukui. After learning that he was in Suzhou Prefecture, he asked Li Zhi to help recruit him.

However, Zhao Hao had high expectations for him. At present, he only asked him to make up for scientific knowledge and had not arranged specific work for him.

~~

Zhang Jian, Zhao Shizhen, Wang Yingxuan, Xing Yunlu, and Qu Rukui are the five major Vajras in the entire research center. In addition, they are just skilled craftsmen who don’t know much about literacy…

Zhao Hao was attacking suddenly today, and the disciples didn't know what he was going to do.

After the greetings, he asked the master what instructions he had.

Mr. Zhao said in his heart that I just didn't want to go hunting, so he smiled and said, "Don't be nervous, I'll just come and take a look."

As he said that, he glanced at Xing Yunlu and said, "Go to your place first."

"Master, please." Xing Yunlu's expression tightened and he quickly turned to lead the way.

Everyone entered the 201 laboratory and saw that the tables and chairs in the house were piled up in a corner, and the empty ground was filled with bags of sand.

Several craftsmen evenly poured several bags of sand written with the same mark on a straw mat, and a snow-white cloth sheet was also laid on the straw mat.

Then every craftsman picked up a fine-toothed bamboo rake and kept plowing the white sand on the straw mat.

Zhao Hao squatted down and looked carefully, and saw that there was a long black stone tied to the teeth of each rake. The stone kept sucking out some black and brown powder from the white sand.

"Is this removing iron for quartz sand?" Zhao Hao asked with a smile.

"Hehe, nothing can be hidden from the master." Xing Yunlu nodded with a smile:

"Last time, the master said that the glass was yellow, green and opaque, mainly because of the impurities containing iron in the quartz sand. After I came back, I thought of this method."

"Well, what's the glass burned now?" Zhao Hao nodded. Xing Yunlu's biggest problem is that he is serious and is especially suitable for doing this job.

"The progress is still obvious." Xing Yunlu asked someone to lift the wooden shelf in the corner of the wall.

There are nine pieces of glass of different colors side by side, and the yellow-green on the left is the thickest, and the color becomes lighter the more you go to the right.

Each piece of glass has a label, with the source of the material, firing duration, furnace flame color and other test data written on it.

It is completely in line with the scientific experimental method taught by Zhao Hao, which makes the teacher feel deeply pleased.
Chapter completed!
