In the early morning, the first light of dawn quietly penetrates into the house, entwining with the gauze curtains, interweaving a soft and mysterious light and shadow.

Prince Fusu slowly opened his eyelids, his eyes still had a hint of confusion from just waking up.

He moved his body gently, lazily and gracefully, while the wooden box beside him lay quietly.

Prince Fusu slowly raised his hand and rubbed his temple lightly with his slender fingers. His brows slightly frowned and he slowly stood up. His plain robe gently slipped off with the movement, revealing his thin but upright body.

He strode to the window and gently pushed open the window frame.

The sunlight fell on the altar, on which was placed a snow-white piece of paper.

He picked up the note, a smile on his lips, his eyes as gentle as jade.

Outside the window, the courtyard was silent, with only a few early birds singing happily on the branches.

There was indeed familiar handwriting on the paper.

After reading what was said above, he shouted to the outside of the door: "Come here, move the mirror to an open place."

...

...

The soldiers outside the door heard the noise and took action.

Soon the mirror was placed in an open space, and then various neatly packed building materials were delivered by the mirror.

When Qin Shihuang heard the news, he rushed over with Meng Tian and Zhang Han.

This was the first time he saw something of such a large scale appear out of nowhere, and he was obviously shocked.

Prince Fusu walked forward and saluted respectfully, as if he was leaving everything to Qin Shihuang to decide.

"Fusu, what are these?"

"Father, these are the materials sent by the immortals to build the Great Wall."

"Cement, bricks and steel bars are the magic tools for building the Great Wall and can ensure the border is forever secure."

Qin Shi Huang stared at these unprecedented things with a burning gaze, and said in a deep voice: "These divine objects are truly a godsend! Fusu, you will continue to be in charge of building the Great Wall. I want to see you in Xianyang before the end of the year."

His meaning was very clear. It was already the winter solstice and the Great Wall had to be repaired before the Chinese New Year.

Prince Fusu bowed, his eyes sparkling with brilliance: "Father, Fusu is willing to build a Great Wall for the Qin Dynasty."

Around them, several ministers brought by Qin Shihuang were talking about it.

Someone questioned: "These materials look like just some powder. How can they be used to build the Great Wall? We have never seen anything like this. Isn't it a joke to just hand it over to Prince Fusu?"

Prince Fusu heard this, smiling, and said firmly: "My Lords, since the immortal has given this thing, it must have a magical effect. We might as well give it a try, maybe we can create a new method of construction, speed up the progress of the project, and reduce the consumption of manpower."

"this……"

Qin Shihuang waved his hand and decided to let Fusu prepare and show everyone the materials given by the immortal.

After a few months, the immortal had gained an extremely good reputation among the people in the border areas.

Hearing that Prince Fusu was going to display the new magical object bestowed by the immortal outside the city, many people came to watch.

At the foot of the Great Wall, there is a busy and orderly scene.

The winter wind was blowing fiercely, and those who could go out at this time were mostly soldiers' families, who were also given a military coat.

Prince Fusu was wearing simple robes and a thick military coat on top. The green coat made his appearance more outstanding, with a hint of handsomeness in his gentleness.

Qin Shi Huang naturally also had a military coat. Wherever he stood, he was definitely a high-ranking official who was decisive in killing people. The years of experience gave him a bit more charm than Fusu.

A group of people stood at the edge of the Great Wall with a solid foundation, with cement, bricks and steel bars given by the immortals piled around them.

The craftsmen surrounded Fusu, some holding wooden hammers and some carrying bricks on their shoulders, waiting for instructions.

Prince Fusu nodded to Mo Yuan and Gongshu Zi, and they both started to take action.

Gongshu Zi took a deep breath and followed what Prince Fusu had said, and began to explain how to use cement: "This cement was given by an immortal. When mixed with water, it can quickly solidify into stone and is indestructible."

“We need to compact the foundation first, then spread a layer of fine sand, and then mix cement and water in a certain proportion and apply it evenly on the sand layer.”

As Gongshu Zi was speaking, Prince Fusu strode over to the prepared items and demonstrated them himself.

He scooped up a shovel of cement and slowly poured it into the wooden barrel next to him. He then added an appropriate amount of water and stirred it with a wooden stick until the cement became a paste.

Then he picked up a shovel and spread the cement paste evenly on the foundation with skillful and powerful movements.

Seeing this, the craftsmen nodded and memorized the movements silently.

Mo Yuan signaled to several Mohist disciples, and they immediately went down and dispersed into the craftsmen groups.

They worked in groups of two or three, cooperating well with each other to spread the cement paste layer by layer and then compacted it with bricks to form a solid wall.

Fusu was guiding them from the side, reminding the craftsmen from time to time to pay attention to the proportion of cement and the thickness of the cement, to ensure that each wall could achieve the best effect.

Gongshu Zi and Mo Yuan led the craftsmen respectively, using cement and bricks given by immortals, to build the Great Wall at an unprecedented speed.

At first, the craftsmen were skeptical about the combination of cement and bricks. They were used to traditional loess and stones and felt unfamiliar with the use of these novel materials.

However, after they mixed the cement and water with their own hands and then combined them tightly with bricks, everyone couldn't help but widen their eyes and showed an expression of disbelief.

"How...how is this possible?" a craftsman exclaimed, and he almost dropped the hammer in his hand. "It is so easy to build the Great Wall with these materials?"

"It's amazing!" another craftsman exclaimed. He wiped the sweat from his forehead and stared at the wall that was taking shape. "I have never seen such a construction method before."

As the wall continued to extend, the craftsmen exclaimed one after another. The craftsmen arranged the bricks closely and then firmly bonded them with cement paste. The whole construction process was smooth and efficient.

"This cement is really great!" a craftsman shouted excitedly, "It makes our work much easier!"

"Yes, yes!" The other craftsmen echoed, "With these materials, we can build the Great Wall much faster!"

The crowd's exclamations and admiration mixed together.

As the sun gradually rose higher, the winter temperature did not rise, but the enthusiasm of the craftsmen who were sweating profusely remained unabated.

Until the sun sets in the west, the sky is dyed with a gorgeous sunset glow.

Next to the Great Wall originally built with stones, a section of the Great Wall built with cement appeared.

In just one day, this small section of the Great Wall had taken shape.

It stands tall and majestic, like a giant dragon winding among the mountains.

The craftsmen looked at their masterpieces with smiles of pride and joy on their faces.

"A divine object!"

“It’s so magical!”

The people who came to watch were also shocked by this scene and were talking about it.

"It is indeed a gift from the immortal."

"That's right. When has the gift from the immortal ever disappointed anyone?"

A man with a pointed face and monkey cheeks in the crowd rolled his eyes and complained, "But why doesn't the immortal just finish building the Great Wall?"
