Soon after, Li Zicheng and Xu Zhengming came to the cafeteria of the Academy of Sciences and stood next to a boiler, in which hot water was boiling, bubbling hot, and the iron lid of the boiler was constantly lifted up, making a "bang" sound.

"Mr. Xu, do you know what your bird's biggest flaw is?"

Looking at everything around him, Xu Zhengming's face was full of doubts, he didn't understand what he was doing here, and then when he heard this inquiry without warning, he was even more puzzled, and replied without the slightest hesitation: "Of course, it can't fly high, and it can't fly far~!" ”

At this time, Li Zicheng didn't say anything, but folded an airplane with paper and threw it out, the moment the paper airplane flew out, the short process of hovering in the air attracted everyone's attention, Li Zicheng's words full of meaning sounded again, and his expression was so relaxed and casual.

"Mr. Xu, you see, I folded this thing, in terms of appearance, it is very similar to your wooden bird, what do you think is the key to its flight?"

"Needless to say? Of course, it was the moment you threw it that made it fly and stay in the air. Xu Zhengming blurted out without thinking, turned his face into thought, and said: "Of course, its appearance is also very important. Otherwise, it would not have been possible to stay in the air for that long. ”

The paper airplane slowly floated down, Li Zicheng's gaze returned to Xu Zhengming's body, and said loudly: "So, Mr. Xu, the fundamental problem why your bird can't fly high and can't fly far is in its power." ”

"Power?" Xu Zhengming muttered at the same time as everyone.

"To put it simply, the so-called motivation is the moment I just throw. If the paper airplane can be thrown continuously, and if there is a force on it, it will stay in the air longer, it will be able to fly higher, and so will your bird. ”

At this time, Song Yingxing stood up and said seriously: "Boss, we understand what you mean, and we also know what power represents. Previously, the reason why I and several academicians of the Academy of Sciences rejected Xu Zhengming's application was that it was impossible to use manpower to drive flying birds here. After all, manpower is sometimes poor, and it is impossible to stare at the pedal all the time, and once there is a slight pause, the bird will fall, causing a disaster of people falling to their deaths. ”

"Haven't you thought about solving this problem?" Li Zicheng asked abruptly, and then added: "The driving force that drives the wooden bird does not necessarily have to be a flesh-and-blood person, or a living thing such as cows, horses, and mules. ”

As soon as these words came out, everyone was immediately stunned, and everyone was dumbfounded, Xu Zhengming opened his mouth even more, and subconsciously asked softly: "Don't use these, so what's the use?" ”

Li Zicheng smiled lightly, did not answer immediately, but turned to look at the boiler, the water in the pot was completely boiling, making a sound of "goo~goo", and the steaming heat lifted the iron lid, and due to gravity, it fell again, and so on.

At the same time, everyone followed Li Zicheng's gaze and looked at the boiler that was boiled, and the sound of wanting to rise and frustrate echoed in everyone's ears, and there was a lot of confusion in their hearts.

"You see, when the boiler is heated, as soon as the water boils inside, white gas comes out and the iron lid is lifted. You say, if we simulate this boiler and make a sealed iron bucket with water in it, the lid of the bucket can be moved up and down in the bucket. ”

"Think of it in your mind, just like this boiler, once the water in the bucket is heated and forms hot gas, it will push the lid of the bucket and move it up and down, so that a driving force can be generated, and as long as the fire is not extinguished and the barrel is constantly heated, this driving force will not disappear."

The people present, except for Li Zicheng, are all top talents of the Academy of Sciences, familiar with the most advanced science in China and the West, with Li Zicheng's slow narration, and then compare the boiler in front of him, the hot gas produced by the boiling water lifts the iron cover, a little association, everyone has a feeling of empowerment, as if opening a new door to an unknown field, Xu Zhengming is even more excited, and the voice echoes in this boiler room.

"Boss, I understand, I found it, and finally there is a way to solve the problem of flying birds, as long as such a thing is made and installed in the wooden bird, that is the heart of the wooden bird, providing a steady stream of power, my wooden bird can fly higher and farther, and it will have practical value!"

Song Yingxing was also excited, and he couldn't help himself, thinking more, and then added: "Not only that, as long as the boiler is used as a model, continuous reform is carried out, and a larger one is created, and the power provided will be greater, which can not only be used to drive wooden birds, but also other machinery in the base area, some water conservancy facilities and mining machinery will be greatly reformed, and the efficiency will be greatly improved." ”

At this moment, the surrounding personnel of the Academy of Sciences were all excited, and it was not difficult to imagine that if such a thing could really be studied, the base area would save a lot of manpower.

Steam wagons, steamboats, steam-powered mining equipment......

The thought of this made everyone feel the urge to make a big move, and they wanted to immediately develop a device that could generate driving force.

At this moment, everyone was looking at the burning iron pot stupidly, the boiling water was steaming white smoke, and the iron lid on the top was clicking, Tian Jianxiu suddenly appeared in the kitchen, trotting, with excitement on his face, and hurriedly shouted: "Boss, the time has come, things are really developing as we guessed." ”

However, Tian Jianxiu's series of shouts did not affect everyone, Xu Zhengming and others were still immersed in new innovative thinking, imagining and constantly improving in their minds, only Li Zicheng turned around, stepped forward to meet him, and asked: "Jianxiu, what happened?" ”

While speaking, the two were already standing together, and Li Zicheng even pulled Tian Jianxiu to walk out, and said in a low voice: "This is not the place to talk, don't disturb them, let's talk in the conference hall." ”

Tian Jianxiu was stunned for a moment, glanced at Song Yingxing and the others, showed a strange expression, and while responding, he also followed Li Zicheng and walked out.

"Okay, boss, Mr. Li Changmao, they are waiting in the conference hall, I am here to call you."

......

In the conference hall, Li Zicheng was sitting on the top, and the upper echelons of the Zhongnanshan base were sitting on both sides below, and Tian Jianxiu was standing in the center of the hall, reporting the news.

"Boss, according to the news we have fed back from the intelligence in Shanxi and Shuntianfu, the Qing army is divided into two wings, about 100,000 troops, and invaded Guanzhong on a large scale.

"The entry of the Qing troops into the customs not only made Lu Xiangsheng, the governor of Xuanda, lead his troops to help, Bai Guangen also sent news, and Hong Chengchou and Sun Chuanting led 150,000 troops to leave Shaanxi, and the troops went out of Tongguan to aid the Beijing division."

"In this way, today's Shaanxi is a virtual reality, and there are no decent officials and soldiers." Li Zicheng stroked his chin and said at the right time, his eyes shining and his face showing deep meaning.

"Yes, boss, not only Shaanxi, but also Shanxi, a large number of officers and troops have been transferred to Beizhili to resist the Qing army."

With Tian Jianxiu's affirmative reply, everyone in the hall suddenly became excited, and their chests surged, remembering the greeting that Li Zicheng had been saying for two years, and two years later, all the Li family's soldiers went out of the base area and overthrew the dark and decaying court in one fell swoop.
