After a few days, almost nearly one hundred acres of land were planted in that wasteland.

Therefore, there were two more tenant farmers under Zhu Zi'an's name!

However, because the wasteland is remote and the fields are also poor and deserted for a long time, no one will pay attention to it.

For the next period of time, the entire Yingtian Prefecture and even the entire Ming Dynasty were trapped in the work of spring plowing.

Several steelmaking furnaces from the Military Intelligence Bureau are still constantly smelting out and smelting steel.

However, the factory outside Zhu Zi'an's city was unified and fell into the atmosphere of creating a small and round glass lenses because of Zhu Zi'an's request.

Because Zhu Zi'an had extremely high requirements, Yang Shifan spent two days and one night in the factory before he could barely create the lenses Zhu Zi'an required.

A glass lens that looks like a baby's palm is twice as thick as the perimeter.

The entire lens is polished very smoothly without any flaws.

Then, Zhu Zi'an combined the two lenses and several exquisite wooden tubes according to his memory.

The workers' craftsmanship is truly exquisite and can be regarded as craftsmanship.

After installation, the slit is tighter than modern machine technology.

After admiring for a while, Zhu Zi'an put it in front of him under the expectant gaze of Yang Shifan and a group of craftsmen, and moved his hands slightly back and forth.

I saw that on the city gate tower a mile away, next to the solemn face of the patrol soldier. However, no matter how far away the place is, no matter how it is adjusted, it still looks like a glance.

As for two or three miles away, I can’t see clearly!

The first time he became a mirror, he was like this, and Zhu Zian couldn't help but nodded with satisfaction.

"Master Yang, this mirror is pretty good, but it still needs a few masters to debug it again!"

As he said that, Zhu Zi'an handed the telescope in his hand to Master Yang, who was already full of curiosity.

"this……"

According to Zhu Zi'an's actions just now, Master Yang put the telescope in front of him. When he saw it, he was shocked.

In the restaurant in the distance, there was a fat and big-eared landlord looking at him with big yellow teeth baring his eyes full of dementia.

"Master Yang, what happened?"

Around him, a group of craftsmen asked with concern.

"Nothing, nothing is wrong!"

After Master Yang put down his telescope, he looked carefully at the big restaurant in the distance again. The small and vague restaurant could not see anything.

I couldn't help but think of something, a hint of surprise flashed in my eyes, and I put the telescope in front of me again and looked at the restaurant.

Sure enough, as his fingers slowly twisted, the big restaurant slowly moved in front of him from a distance. Suddenly, Master Yang couldn't help but tremble again, and the fat big face appeared in front of him again.

Then, a trace of shock flashed in Master Yang's eyes, as if he was seeing something magical. His hands kept moving back and forth, holding the telescope, and constantly taking the initiative around him.

After a long time, I stopped with an unfulfilled look on my face.

He handed the telescope in his hand to several craftsmen who had already turned red.

"Ah...ah..."

"Oh my God!"

Suddenly, the craftsmen were like Yang Shifan, with a look of surprise on their faces.

Looking at Zhu Zi'an, there was a little fear in his awe, as if he had seen the heavenly gods and immortals in the Taoist temple.

"Little real person, is this thing a fairy's eye?"

After Yang Shifan's expression flashed for a while, he slowly asked Zhu Zi'an.

"This thing is just a glasses, not what you think!"

Seeing this, Zhu Zi'an couldn't help but burst into laughter.

"Of course, it can also be called Clifford. The production structure and objects of this telescope are made by your hands, and there is no strange power!"

"But, this Qianliyan only uses two glass mirrors and a few wooden tubes, which is..."

Yang Shifan stared at him for a while, and the telescopes in the hands of several craftsmen on the side turned their heads again and saw Zhu Zian with a smile on his face.

This time I nodded slowly, but the shock in my eyes still did not dissipate.

"Master Yang, the manufacturing process of glasses is very simple, but the requirements for lens polishing process are extremely high. Next, I hope Master Yang will spend more time and create more telescopes."

"This telescope can only see objects one mile away at most. For objects farther away, it will be blurred. However, I am planning to present this telescope to the emperor for use in the army, so there is a need for telescopes that can be seen farther away.

Therefore, Master Yang asked Master Yang to debug it a few more times, adjust the size and thickness of the lens, and create a telescope that can see farther away!"

Finally, Zhu Zi'an instructed.

"Yes, please rest assured by Xiao Zhenren!"

When he heard that it was presented to the emperor and used in the army, Yang Shifan looked even more solemn.

Seeing this, Zhu Zi'an also felt relieved.

After seeing the magical effect of the glass mirror that he and others had created for two hard days, Yang Shifan and a group of craftsmen were even more motivated.

After a little rest, I immerse myself in the experiment of polishing the lens and debugging the lens.

During this period, something happened among the officials in Yingtian City, whether it was big or small or small.

Mr. Tieya, who had invited the emperor several times, but failed, actually came to Yingtian City by himself.

Moreover, I will help Song Lian compile the dictionary.

At the same time, the officials who compiled the dictionary with Song Lian were actually Wang Qi, the magistrate of Zhangzhou Prefecture, who had already served as a major literary scholar who was an official outside.

As for the officials in Yingtian City, the emperor only found a few officials with little reputation.

This situation disappointed the many civil officials in Yingtian City who were looking forward to it.

...

And the time before the first sight glass was created is five days later.

Zhu Zi'an's 100 acres of fertile land outside Yingtian City have also been cultivated. The wasteland around the factory has also begun to be cultivated.

Just as Zhu Zi'an was staying in the mansion and was taking a break, Yang Shifan held two more looking glasses and found Zhu Zi'an with anticipation.

Zhu Zi'an stood on the roof and looked for a while. He found that he could see the big tree ten miles away as far as possible, and then he could no longer debug it.

Zhu Zian could also accept this with pleasure.

This is not because Yang Shifan and others are not skilled, but because the lens itself is insufficient.

However, this ten-mile telescope is also a magical weapon in the marching and war of this era.

"Master Yang, according to this distance, he created another sixteen telescope!"

"yes!"

Yang Shifan quickly responded with a happy expression and ran to the outer city factory with his telescope.

Although the fields and factories were running at the same time and had been working hard for many days, Yang Shifan still felt that he was full of motivation and without any fatigue.
