Xianyang Academy, Institute of Technology.

Withered yellow leaves fell to the ground, and occasionally a cold autumn wind blew by, making a rustling sound.

A group of students from the School of Engineering, wearing only thin blue clothes, gathered around a drawing and had a heated discussion, as if they were not afraid of the cold.

"Can this so-called telescope really see a thousand miles away?"

"Do you all remember what the Saint Mo said, 'When the scenery arrives, there is a beginning at noon; when the scenery grows, the end is there'?"

"I've kept it in mind. I think the principle behind this diagram is similar to mine."

"Indeed, if it is truly developed, even if we can't see a thousand miles away, it will not be difficult to see within a hundred feet."

“…”

Everyone expressed their opinions and talked freely. Everyone looked excited, and there was a flame of enthusiasm burning in their eyes.

As disciples of the Mohist school, they had already memorized the Mohist Classic by heart.

Naturally, many people have studied the pinhole imaging principle mentioned by Mozi, and even experimented with it themselves.

The reason why Mohism became a school of thought on par with Confucianism was not only because of their achievements in siege equipment, but also because of their pursuit of the laws of all things.

They are not carpenters or craftsmen, but inventors and innovators, and their pursuit of truth never stops.

Now, an opportunity to inherit the unique skills of the ancient sages is right in front of them. How can they not be happy? How can they not be excited?

"Everyone, let's get started. We need to develop the telescope as soon as possible so that we can live up to the high regard that His Majesty and His Majesty place on the Mohist School."

"That's absolutely right."

“…”

The disciples of Mohism were pragmatic, and after the excitement of the moment they immediately plunged into research. They sometimes discussed, sometimes tried, divided the work and cooperated in an orderly manner.

With the experience of successfully making glass, the development of convex and concave lenses was not difficult. Ten days later, everyone worked together to develop a monocular telescope.

Although its appearance is a bit simple, it does not affect its practicality. However, in order to achieve better experimental results, the students came to the top floor of the dormitory building.

The leader Mo Guan was the first to pick up the telescope, facing the tube with one eye and closing the other. After focusing his vision, he could clearly see the scene a hundred feet away.

It was lunchtime now, and groups of students were walking towards the dormitory. Their facial features and expressions were clearly visible, and Mo Guan couldn't help but exclaim.

"Every detail is visible! Every detail is visible! It's truly worthy of being called a thousand-mile mirror!"

"Is it so magical? Let me see it..."

"I want to try it too!"

Hearing Mo Guan's excited shouts, everyone guessed that this thing must have extraordinary effects, and they immediately became itchy and wanted to experience it for themselves.

After some "friendly exchanges", the students lined up in an orderly manner to experience the telescope, followed by continuous exclamations from the top floor.

The students downstairs who were being spied on always felt like their backs were being thorned. They looked around for a long time but didn't notice anything unusual. For a moment, their faces were stiff and their hair stood on end.

It's broad daylight, there shouldn't be any ghosts, right?

A few days later, the disciples of the Mohist school developed a binocular telescope with a stronger sense of three-dimensionality based on the monocular telescope.

When they looked through the lenses and clearly saw the six large characters "Inheriting the Secret Learning of Past Sages" on the stone tablet, for some reason a spark of brilliance suddenly appeared in their eyes.

The next day, in Zhangtai Palace.

"Yuening, could this be a telescope?"

Ying Zheng opened the wooden box and picked up the so-called telescope to examine it carefully. It looked like two bamboo tubes inlaid with four pieces of glass, strange and crude.

Looking at the puzzled look on the man's face, Chu Yuening curled her cherry lips, and her bright eyes flashed with cunning.

"A Zheng, don't you believe it?"

"Once we try it, we'll know how wonderful it is."

As soon as she finished speaking, she couldn't wait to take the man's hand and brought him to a high platform outside Zhangtai Palace.

The telescope was very simple to use, and Ying Zheng mastered it quickly. He then put his eyes to the tube, focused his gaze, and looked into the distance.

The palace walls built of stone bricks, the rows of tiles, the palace maids sweeping fallen leaves, the geese migrating south...all are clearly visible at a glance.

"This telescope is truly extraordinary and truly lives up to its name of Thousand Miles."

After a long time, Ying Zheng reluctantly put down the telescope. The excitement between his brows was hard to suppress, and he couldn't help but praise loudly.

Although he had never led troops in battle, he was well versed in military strategies. How could he not see the great military value of the telescope?

The winning factors of a battle are not just the number of troops. The planning of the battle, the exploration of the enemy situation, the grasp of timing...even the climate and temperature are crucial.

The Xiongnu lived wherever there was water and grass, and their residence was not fixed. Their cavalry were good at taking advantage of rugged terrain, advancing when it was advantageous and retreating when it was unfavorable, making it difficult for the Qin cavalry to pursue them.

However, now with the telescope, they can detect the enemy situation in advance and carry out blocking and encirclement, which can increase their chances of winning by at least 10%.

"Hey, of course!"

"Once the Mohists develop a telescope with a higher magnification, we can see even farther."

Chu Yuening took the telescope and tried it out. Although it was not as good as modern telescopes that could see a thousand meters away, it could still see four or five hundred meters away, which was already very good.

After all, this was only the first generation of telescopes. She believed that with the Mo family's outstanding talents, it would continue to be improved and upgraded to the second and third generations...

Ying Zheng looked at the woman's lively and agile demeanor, with a faint smile in his phoenix eyes. He held her slightly cold little hand and planned to return to the palace.

Unexpectedly, Chu Yuening pulled him towards another palace, with a smile on her pretty face, revealing a hint of mystery.

"A Zheng, the telescope is just an appetizer~"

"I have prepared an even more powerful treasure. You will definitely like it."

"Okay, then I'll wait and see."

Ying Zheng smiled indulgently at his wife's childish little tricks. He cooperated and followed her pace without asking any further questions, patiently waiting for a surprise.

Soon, the two came to a somewhat deserted palace. Some wood and utensils were piled on the open space outside the palace.

Ying Zheng looked around and suddenly felt that it looked familiar. When he caught sight of the plain cement floor, a flash of understanding appeared in his eyes.

"Could this be where Mo Qing once lived?"

"Yeah, yeah, I didn't expect A Zheng still remembered it."

Chu Yuening chuckled and joked playfully as she led him towards the palace entrance.

Since the academy was built, Mo Ju has taken root there. The palace has been abandoned for several years, but the palace servants still clean it regularly.

With a creaking sound of the door, the two of them walked into the silent hall hand in hand.

The treasure that had been silent here for half a month finally bloomed with dazzling brilliance at this moment.

After seeing the treasure clearly, Ying Zheng's expression became serious, and surprise, excitement, and joy flashed across his deep pupils...
