I have already established my power and prestige, so how did Li Shimin come back to life?

He knew that the key material that the craftsmen had been searching for but had never been able to find must exist somewhere in the world, but it had not been discovered yet.

Later, when it came to the last step, Li Chengqian knew what was needed just by listening to their description.

When Cui Dayong walked into the third laboratory, he saw the completed rubber molds neatly arranged on the workbench, emitting a unique luster.

His heartbeat suddenly quickened and his eyes were filled with excitement.

Cui Dayong carefully picked up a rubber mold. The mold was soft and elastic, and felt cool to the touch.

He gripped the mold tightly, turned around and ran towards the factory, his steps eager and determined.

When the workers of the entire Ministry of Industry heard the news, they put down their work and followed Cui Dayong without hesitation.

Their eyes were also full of anticipation, and no one wanted to miss this critical moment in history.

Although no one had ever truly witnessed the magical effects of rubber before, the material was sent by His Majesty himself, and the concept of the steam engine was also proposed by His Majesty.

In their hearts, His Majesty's words are sacred and inviolable golden rules. Since His Majesty said that this thing is feasible, they can't help but develop an almost blind firm belief - what His Majesty said must be true!

With a nervous and excited mood, Cui Dayong slowly put the rubber in his hand onto the cylinder and valve of the steam engine.

His hands were trembling slightly, beads of sweat appeared on his forehead again, and his eyes were focused and solemn.

He took a deep breath, tried to calm himself down, swallowed, and said in a slightly dry voice: "Let's start the first experiment!"

Several craftsmen looked at each other and saw encouragement and determination in each other's eyes.

They nodded firmly, and then worked together to slowly pour the coal into the boiler.

As coal was added, flames gradually ignited in the boiler and the temperature rose rapidly.

A moment later, the steam engine emitted a dull roar, the sound was a little hoarse at first.

Then, the sound became louder and louder, like the roar of an angry dragon, and the powerful sound waves echoed throughout the Ministry of Industry.

Steam continued to rise from above, in an endless stream.

Time passed slowly in the roar. A quarter of an hour later, the steam engine was still running stably without any abnormalities.

Half an hour passed, and it was still working tirelessly. The piston moved back and forth in the cylinder, driving various transmission devices to operate in an orderly manner.

An hour passed, two and a half hours passed...the steam engine continued to run steadily.

It was not until the coal in the boiler was gradually burned out and the fire gradually weakened that the roar of the steam engine gradually subsided and finally stopped working.

At this time, the white smoke above the steam engine seemed to have lost its support and slowly dissipated into the air.

When everyone looked closely, they found that the coal had been burned out, but surprisingly, there was still a quarter of water left.

At this moment, someone could no longer contain their excitement and shouted, "We succeeded! We can go home now!"

This cry instantly ignited everyone's long-suppressed emotions.

The entire Ministry of Industry suddenly erupted in deafening cheers, which were filled with joy, pride and relief.

The eyes of many craftsmen were moist and tears flowed uncontrollably.

After countless days and nights of hard work, countless attempts and failures, they finally ushered in the dawn of success.

This means that the Tang Dynasty is about to usher in a brand new era, a new life full of hope and infinite possibilities!
