Not long after the mine making process handed over to the R&D Institute, the R&D Institute mysteriously sent an invitation to Li Tianyang to go to the R&D Institute in person, saying that there were major research results.

Li Tianyang is now busy with official business, where does he have time to go to Bengang, delay a day or two to play mysterious games with the people of the R&D Institute, and immediately refuse to go to the past.

However, soon, the R&D Institute sent an invitation again, and Chengcai, who had not shown up for a long time, wrote a letter to Li Tianyang in person, which immediately aroused Li Tianyang's curiosity.

Carefully calculated, Li Tianyang has not met with Chengcai for a long time, and even this year's Shangyuan Festival, Zhongyuan Festival, etc., Chengcai did not come to Jilong Town to celebrate the festival with Li Tianyang and Yumo.

When I was last year, I heard from the people of the R&D Institute that Chengcai was busy with a major R&D project with the backbone, and most of the funds approved for the R&D Institute last time were used by Chengcai for their R&D projects.

Therefore, when Li Tianyang received a letter from Chengcai's brother-in-law, Li Tianyang, who had no leisure, adjusted with the staff of the secretariat for two days on the spot, and took a sea boat to Bengang in the afternoon of the same day.

The R&D institute is now growing in size, and two or three years ago, with only a few hundred research members, has tripled in size, and its buildings surround the entire valley.

This reflects the significance of Li Tianyang's emphasis on education at the beginning, and with the graduation of the children of Bengang School in batches, all kinds of talents under Hongmen's command have emerged in endlessly.

In the R&D institute, it is no longer the original disorganized, everywhere placed all kinds of strange objects, Li Tianyang sent to assist in the management of personnel, although the two years in the research and development has not made much contribution, but for the daily life of these R & D personnel, the management of the base, is very effective.

Led by the team members, Li Tianyang and the others walked all the way into the depths of the valley, which was a place that Li Tianyang had not visited several times before.

From a distance, Li Tianyang saw a huge and swarthy object with a towering chimney, and the chimney was still emitting his aunt's black smoke at this time, and at the same time there was a huge roar.

Listening to the roar with the sound of metal colliding, and at the same time with a strong sense of rhythm, I don't know why, Li Tianyang has a very familiar, but a little unfamiliar.

"I knew you were going to arrive today, so I didn't pick you up, but I was here to prepare to launch this big guy and let you see what we have achieved for more than two years!!" Chengcai was wearing a gray coat at this time, and the sweat on his face slipped down his face, and he could draw tear stains, and it turned out that Chengcai's face was covered with too much dust.

In the noisy environment, Li Tianyang had some difficulty listening to Chengcai's words, and was about to ask what was going on with the big guy in front, when suddenly next to the chimney in the back, a snow-white heat wave came from the surface, and with a sharp stabbing sound.

Six or seven zhang away, Li Tianyang could feel that the air, which was originally a little hotter than outside, was not only two points hotter at this time, but also had a moist touch, which made people involuntarily start to sweat.

"What is this?" Li Tianyang worked hard to improve his voice, so as not to be affected by the noise and environment, and they could not hear clearly.

"Hey, hey, hey, this is the latest masterpiece of our R&D Institute!" Chengcai replied proudly and confidently, and at the same time took Li Tianyang and continued to walk forward, seeing the true face of this object that emitted a huge noise.

It is a metal structure made entirely of steel, resembling a Maitreya Buddha with a huge beer belly.

On one side, there are Hongmen team members who are shirtless and completely black, constantly shoveling black objects on the side and sending them into the creation; On the other hand, under the unknown effect of this creation, the gears and transmission shafts on the creation moved slowly, slowly and steadily turning, bringing up a crushing hammer that looked like it was used in the mine, and sending a cast iron hammer weighing about 100 catties from low and high to the highest place, and then quickly fell freely, and brought up the crushed stone dust in the ore in the crushing tank.

I couldn't really see it from a distance before, but after walking closer and carefully observing the general principle of this steel object at close range, maybe other people in this era may not know what this thing is, but Li Tianyang, who traveled from later generations, can immediately conclude that this is probably the epoch-making product!

"This !!" Even if he knew what this thing was, Li Tianyang's eyes were still surprised, incredible, magical, and so on.

"Brother-in-law, do you remember the book of physics that you compiled at the beginning? You also left a question in the Enlightenment book at that time, do you remember what the problem was? Looking at Li Tianyang's dumbfounded expression, Chengcai was very relieved, since he was a child, this brother-in-law in his eyes was like an encyclopedia, as if there was nothing in the world that he didn't know, even if he had a novel object researched by their research and development institute, Li Tianyang could tell his function at a glance, which made Chengcai, who regarded research and invention as his life goal, very frustrated!

“…… Why is the kettle on the stove always lifted up by water vapor? Li Tianyang subconsciously said this problem that he left in the book of physics enlightenment.

“…… Yes, that's the question! The expression on Chengcai's face froze for a moment, and then he returned to his normal state and continued to explain Li Tianyang's confusion: "In the physical enlightenment, it was once said that everything is divided into three states: solid, liquid and gaseous. ”

"The solid state of water is ice, and its gaseous state is water vapor, and we have found in our research that after water changes from liquid to gaseous, its volume will become very large, which is probably the answer to this question that you left in the first place, brother-in-law." Chengcai's face was full of memories of the joy when the questions that had puzzled him over the years were answered.

"Afterwards, after we solved the answer to this question, we wondered if we could take advantage of this change in the state of matter and do something about it, so that we had the prototype of this big guy!"

"Does it have a name?" Li Tianyang looked at the miracle in front of him in a daze and muttered.

"Water burner, how about it, vivid enough!" Chengcai replied proudly.

"No, that's not enough to describe how it works, it sounds twisted, or I'd better give it a name!" Li Tianyang shook his head, with a dissatisfied look on his face, and made a conclusion in an unquestionable tone.

"From now on, it's going to be called a steam engine!!"
