Shen Feng smiled at the very peace of mind, looked at the cloud and said: "Let go and try, no need to worry, the sky fell down and I was carrying you!"

He smiled, then took a deep breath and nodded.

I saw a craftsman walking to the stove, and after the ignition, he added a lot of coal to it, all of which were high-grade coke coals, and the quality was excellent.

Another craftsman went to the end of the metal shaft at the other end of the prototype and installed a simple wooden wheel!

There is a simple rotating wind box next to the stove, and the craftsman began to shake the handle of the windshield and constantly blow the wind into the furnace, so that the coal inside the combustion as soon as possible, but also the more prosperous.

It didn't take long for Shen Feng's ear to hear a snoring sound, so that his heart could not help but shock!

Above the stove was sealed, and there was a pipe connected to the steam-machine prototype, and some water vapor came out a little outside the gap in the pipe, making a hickey sound.

This is also very normal, under the level of this technology in the Tang Dynasty, there will be some gaps in the sealing of the pipeline, there will be some steam leakage, and the early emergence of the steam engine in the future will have the same phenomenon!

Shen Feng's heart was even more excited, the heart pounded, and then went to the direction of the prototype, and then saw a moment later, then a few things above the machine began to move slowly up and down, the speed is getting faster and faster.

This is the piston on the steam engine cylinder!

The piston has been able to start working, and the speed is getting faster and faster, Shen Feng's heart is even more excited, but still not rest assured, put his eyes on the prototype.

Only the piston on the prototype began to run rapidly, not only that, the state was also very stable, and the whole prototype was only slightly trembling, and there was no violent jitter.

This is naturally Shen Feng's great concern, only to achieve this, the steam engine can achieve continuous operation, a steady stream of power!

Shen Feng's eyes fell on the metal long shaft at the other end of the steam engine, which is another key to determining the success of the prototype steam engine.

This long shaft is a steam engine-powered output device, and the internal connection is a crank-linked shaft, which can turn the up and down movement of the piston into a continuous circular motion!

Soon, I saw that the metal shaft began to slowly rotate, and the simple wooden wheel that drove the other end also began to turn, and the speed was getting faster and faster, and the state was extremely stable!

The snow of steam, the thump of metal thumps brought by the reciprocating movement of the piston, and the click of the wooden wheels as they rotated, were like a beautiful concerto in the ears of the Shen Feng, which made Shen Feng's heart feel extremely happy and happy!

The prototype of this steam engine was successful!

Standing next to Shen Feng's face on the face of the cloud is also very excited, after all, this prototype was assembled from the part state last night, but a little bit of debugging, this time in front of Shen Feng is the first real boot operation!

And this time it was successful, and the prototype of the steam engine began to operate continuously and steadily in front of everyone!

Shen Feng's heart is also extremely happy, fortunately he put the steam engine drawings into the hands of the cloud, the manufacturing method told him, and only the cloud and these craftsmen have such a ability and means to produce high-quality and high-precision parts, assembled this steam engine prototype can be successfully turned on, so good and stable operation!

“Prince, can you see such a prototype?”The cloud turned to look at the Shen Feng and asked.

Shen Feng was also difficult to hide his excitement when the look, turned to look at the cloud nodded, the voice slightly trembling said: "Okay, this machine is really very good!"

Looking at the prototype of the steam engine in front of him, Shen Feng's heart is up and down, excited.

From now on, such an epoch-making invention as the steam engine appeared in the Tang Dynasty of China.

With the prototype of this steam engine, and the craftsmen of the thousands of herons, the steam engine will soon be put into use in the army, equipped with the fifty copper spray trains, and become their engine.

In not long, the steam opportunity slowly spread to the people, in many places can be more widely used!

The emergence of such a thing as the steam engine is like lighting up the scientific and technological tree of Chinese civilization, and can transform China from an agricultural civilization into an industrial civilization nearly a thousand years in advance!

And after the two things of gunpowder and steam engine have been widely used, what kind of scene will be the Chinese civilization in the future, Shen Feng is also dare not imagine!

Shen Feng took a deep breath, and this journey through time and space was really worth it!

“The Prince, the King!”

Seeing the Shen Feng standing there straight without speaking, it was very surreal, and the cloud hurriedly opened its mouth and called.

And Shen Feng came back from the infinite thoughts and excitement, and the "um" responded.

“Prince, what were you thinking?”The cloud looked at Shen Feng and asked a question.

Shen Feng returned to God and thought for a moment, then turned to look at the clouds and said, “O cloud, after the world is settled, you and these craftsmen in the camp of the gods will not stay in the army again, or return to your Ministry of Industry.”Stop studying the ordnance used in these wars and killings, and do a good job of making your inventions, and getting things like the steam engine well.

“Really?Did the prince let me leave the army and go back to the Ministry of Industry?”The cloud will look at the letter suspiciously Shen Feng and say.

Shen Feng nodded extremely solemnly, and said in a very heavy tone: "Yes, after the world is stable, there is no war, the people live in peace, and it is a great waste to leave you and these thousands of craftsmen in the army!"Go back to the Ministry of Industry and change everything in this world with your minds and hands!”

After listening to this, the cloud was obviously very excited and nodded his head in a hurry.

“Thank you, Prince!The cloud was originally a monastic, and the heart was merciful to the life of the world.Let me develop all kinds of ordnance in the ordnance prison and the army, and these are the murder weapons that kill people, which is also a kind of suffering for me!Thank you to the king for his compassion for the clouds, and thank you for the clouds!After the world is settled, the clouds will be exhausted and seek the well-being of the world.”
