Gao Buer gave a salute to this Yan Gushi and praised: "The old master is worthy of being a senior with a good heart, and everything is based on serving the country, and I am ashamed, but if a new tool is invented to improve the speed of people, it can shorten the time distance between the north and south of the river and the imperial court, and deepen the connection with the capital, is it more conducive to governing the place?" ”

Yan Gushi nodded, now the land of Nanyue and the land in the west are all separated from the imperial court because of the distance, if you really want to invent this kind of tool, it is definitely a sharp weapon.

Gao Fuji expressed his gratitude to Yan Gushi for his recognition and continued: "Inadvertently, my students and I discovered a very interesting thing, this phenomenon can be seen by everyone every day, that is, whenever the teapot we use to boil water is boiling, the teapot lid will keep jumping up and down, isn't it? ”

Zhu Tianluan said: "This is very common, what's the problem? ”

"There's no problem, it's just that I'm wondering if it's a force that lifts the lid of the teapot? Can we harness this power? Therefore, this non-compatriot student and a group of alumni in our college have been working day and night to study this. ”

"What's the catch?" Someone in the crowd asked.

Gao Fuji said proudly: "Yes, quite large, we have discovered a power that can work without relying on manpower, and can travel far without the strength of livestock, and that is the power of steam. ”

Confucius Ziyu was suspicious: "You are exaggerating, we have all seen the teapot lid, this kind of power does not seem to be as mysterious as you say." ”

"That's why we make bold assumptions and carefully verify them."

Yan Gushi said: "Can there be results? If the old man remembers well, the water wheel you invented before can draw water to a high place by the power of the water, which is very amazing, and if you can find a force that does not rely on human power, it is not impossible for the old man to admit that you are a new learner. ”

"The old master is old and virtuous, and all the boys he says are ordered. After more than a year of hard work, we have achieved some results, but because the sealing problem has not been well solved, it can only be tried on a sampan boat. ”

"In any case, it is worth affirming that you can take the first step, but can you demonstrate it live?" Yan Gushi is a little anxious, this old gentleman has worked hard for the country all his life, but unfortunately the years are like knives, he cherishes time very much, if he can see some new things that affect future generations in his lifetime, he will be satisfied.

Gao Fuji did not disappoint him, in order not to make everyone wait for a long time, he took everyone to the Slender West Lake, where a simple dock has been temporarily built, and a sampan boat is parked on the dock, the size of this boat is no different from the common one, but a platform is set up in the middle of the ship, and there is a black cylinder with a diameter of the same width as the ship on the platform, and it is impossible to see what material is made.

Yan Gushi pointed to the cylinder and said, "This thing is your invention?" ”

Gao Buji was a little shy and said: "Exactly, after more than a year, after continuous experiments, I am really ashamed to have developed such a thing now." ”

"There have been small achievements, how can I be ashamed to say that sailing ships have existed for thousands of years, not like that, you have such achievements for more than a year, you are already a genius."

was praised by the respected old master, and Gao Fuji could only bow down and be taught.

Gao Fuji signaled to Wen Ren, who was already waiting on the boat, to start the test, and Wen Ren did not know that Gao Buji had instructions, and motioned to the strong man behind him to untie the cable and start adding coal to the furnace.

I saw that the strong man added a burst of coal, and then operated the fan for a while, so that the coal burned quickly, and when the water in the boiler began to boil, the strong steam pressure pushed the piston and began to slide up and down, and under the action of the bearing, the propeller under the water in the stern of the ship began to rotate, and the sampan boat began to slowly slide away from the dock, and Wen Ren did not control the rudder to keep the hull in a straight line.

When the crowd standing on the shore saw this scene, their eyes widened in surprise at first, and then they didn't know who roared: "Oh my God, this boat ran away on its own without manpower or wind, it's amazing, this is the power of God." ”

Although this statement is despised by many people, one thing cannot be wrong, the ship is sliding by another force, and it will be a groundbreaking event.

Yan Gushi was a little excited and cried with joy, and said speechlessly: "Oh my God, you can see this miracle in your lifetime, and you will die without regrets." ”

Afraid that he would faint, Gao Buer stepped forward to support him and said: "The old master is a very rare living auspicious man in the country, you will be able to prolong the years of the crane back then, and you can see more good things in the future." ”

Yan Gushi didn't think it was contradictory, nodded again and again, and asked: "This ship should be driven by those machines on that cylinder-like thing, but what is its mechanism, can King Zhou solve the confusion of the old decay?" ”

"Others may not be able to, but the old master asked, of course he learned that everything is endless, and it is not worth mentioning to say it, you look at the cylinder, we call it the steam engine, it seems to be connected as a whole, and the interior is actually divided into two layers, the lower is the boiler, and the top is the pot and the piston, which you can tell from the smoke coming out of the upper and lower chimneys."

Yan Gushi stared at it for a while, nodded, and saw that the chimney above was white smoke, and the chimney below was blue smoke.

Gao Fuji continued: "The inspiration came from the stove and the teapot, except that the teapot lid boy made it into a piston and the teapot into a piston cylinder, so that the piston could move within a controlled range under the action of steam. ”

Yan Gushi thought for a long time and said: "You really have a wonderful design, if you can get some help from everyone, you will definitely have other inspirations." ”

Hearing this, Gao Buji immediately said: "Please also ask the old master to teach me and introduce me, the financial boy will not hesitate." ”

Yan Gushile said: "Let's talk about it here, besides, those characters have been passed down for thousands of years, and they are not something that money can be touched." ”

"The kid has been taught, so please ask the old master to bother more."

Yan Gushi nodded in agreement, and said at the same time: "The condition you mentioned before that we gambled on losing your selection of manpower is probably also because I think there is a shortage of available manpower." ”

"The old master sees it."

"Then choose well, there are many unborn children of the family in this group, you can get twice the result with half the effort if you get it well, and I will find a list for you when I go back."

Gao Fuji was overjoyed, if he really wanted to sleep, someone would send him a pillow, so he once again thanked Master Yan.
