The principle of a steam engine is to convert the energy of steam into mechanical kinetic energy. The invention of the steam engine is a symbol of the industrial revolution, which formed the most important prime mover.

Qin Feng slapped his head, yes, how did you forget the steam engine? Compared with internal combustion engines, the steam engine is the easiest kinetic energy to achieve. It only requires a boiler that boils water to produce high-pressure steam!

There is no coal, oil or natural gas now, but there is a large amount of wood, using firewood as a heat source, and steam expands to push the piston function, so that the steam can enter the inside of the steam machine!

This drawing should have been trimmed many times, and the cylinder, base, piston, crank connecting rod mechanism, slide valve steam distribution mechanism, speed control mechanism and flywheel have been drawn and marked.

Although Du Chen is an executive, he has a specialty in his profession and is the top management. However, he cannot succeed in mastering such technical skills. He must have tried it repeatedly like purifying himself. He has obviously studied 80% or 90% of the steam engine, but has not used it!

Qin Feng felt frustrated. Those aristocratic families were really stinking stones that stopped the change. Qin Feng’s face was not very good-looking, while Xiao Lingyao frowned at the strange-shaped thing on the drawings: “What’s the use of this thing?”

"Can you increase production capacity, can you believe it? The soda that comes out when boiling water can be turned into a driving force through this machine to do higher-intensity work. This is the result of your great-grandmother's thoughtful research. This thing..."

"This thing was named Steam Engine by her." Qin Feng said: "Looking at the drawings and explanations has come to the end of the study, but she did not have time to use Daqi to destroy the Chao Dynasty. She hurriedly wrote these achievements in English and recorded them in history books and handed them over to Mr. Cheng."

If Lu Qi, the head of Fusheng Pavilion, was obsessed with drawing geological maps, just providing him with financial resources and mineral resources, the last emperor and later left behind are simply basic templates prepared for the Ku Cliff.

The drawings of the steam engine are undoubtedly a qualitative breakthrough. Qin Feng's heart was ups and downs and he excitedly held Xiao Lingyao's hand: "Your Majesty doesn't know these, these will be the bargaining chips for us in the future."

Speaking of the bitter cliff, Xiao Lingyao said in a deep voice: "I have contacted there after leaving the city. In addition to asking for a letter from Ah Niang to send His Majesty, I also know that the personnel drawn by the escort agency and the rest station have arrived. Now the city is afraid that the speed will be accelerated."

Qin Feng knew what she meant. There was not enough power these days, and there was no lift freight machine, which relied on basic kinetic energy and personnel. Although there was a little more manpower at present, it was far from enough!

But their situation in Sui City is getting more and more difficult. If it is delayed, it is very likely that Emperor Yuan will notice it. Qin Feng breathed out and said firmly: "Since that is the case, evacuate in batches."

"What about silver?" Xiao Lingyao said: "How long will it take to transfer it?"

"I have transferred all the business names except Takuhai to Fang Zheng's name. Your secret guard needs to be both Leng Ruohan and Fang Zheng in the future. Taking advantage of the headache of His Majesty, who is trying to seize the flying dragon talisman, we will speed up the withdrawal of cash silver or gold."

Exchange all silver notes into platinum or gold so that they can maintain their value. However, it is inconvenient to transport them. However, silver notes can only be exchanged within the territory of Dongyue, and traces will be exposed at any time. If you enter the Ku Cliff, you will be like a blank paper!

"Do you know that this evacuation will inevitably lead to leaking news?" Xiao Lingyao frowned: "There are too many people, and it is difficult to control."

Nowadays, the people who sent to Kuyao are all those who have signed a death contract with Qin Feng. They are loyal or have to be unfaithful. After entering Kuyao, they will naturally be restricted and will not be released. Be sure to keep the news tightly.

Moreover, it is not easy to get out of miasma forests. The southwest is remote. There are really people who don’t want to stay there to think about it, in addition to considering it, it is even more difficult to pass the news from the southwest to the capital!

But now it is a large-scale evacuation. Qin Feng is an imperial merchant after all, and Kunpeng is famous. How to withdraw, how many people are evacuated, and how many people are willing to follow. These are all problems. All those who can move around the periphery are moving. This group of Suicheng is not easy to deal with.

"This time I was imprisoned by His Majesty is a touchstone. After the news of my disappearance came out, a group of people thought that Kunpeng was going to be finished, and even wanted to find a next home. This group of people was screened out by Manager Fang and others and would not take them away."

The master has nothing to do, but he hasn't seen it yet. These people can't wait to protect themselves. How can they use it?

This matter helped Qin Feng eliminate a group of people. Qin Feng put this matter aside first, looking at the paper in his hand, there were too many contents and too many professional terms. He was a human brain, not a computer, and it was difficult to remember all of his memories in an instant.

Before evacuation, he planned to spend some time memorizing these contents, remembering more of them, and keeping the drawings well and taking them to Ku Cliff together with those geological maps!

The evacuation should not be urgent. The most urgent thing is to quietly turn the liquidable funds into gold and silver first to take them out of the city. Previously, Wu'an Hou guarded the city gate, and the convenience of this matter was greatly improved. But now Wu'an Hou has been transferred away and has fewer his own people.

However, Qin Feng thought of another person in his mind - "General Guo Shen can be used."

The poor Guo Shitong, who was on duty, sneezed hard, and didn't know that he was about to become Qin Feng's springboard.

The two of them pulled Guo Shitong into the plan and were about to discuss what happened next. Agarwood sounded outside: "Your Highness, the prince consort, and the people from the Second Prince's Mansion sent a batch of gifts. I wonder if it could be accepted?"

Xiao Lingtang? Qin Feng raised his eyelids. Shouldn't this guy hate them now and gritted his teeth and actually sent a gift?

In the idea of ​​being polite and finally making money, of course, I would like to collect it. After receiving Qin Feng's instructions, Chenxiang immediately walked away. Xiao Lingyao tasted the meaning of it and smiled: "The second emperor is better than the eldest emperor."

There is no benefit in opposing them now, and winning over is the best way to dispel His Majesty’s suspicion of him as soon as possible. As long as he guides His Majesty’s idea of ​​being wronged, it is right. I am afraid that he is thinking about leading the fire to the third place, so that he can get out of here.

Now, it is for His Majesty to show kindness to them. Xiao Lingtang is much smarter than Xiao Lingzhao, but the two have a common characteristic - they have a very good background and win at the starting line at birth. They have a common problem, that is, arrogance.

Nowadays, no matter how arrogant a person is, he will show his goodwill with a shameless face in the face of crisis. Qin Feng sorted out the pages and took them to himself, and decided to see what good things Xiao Lingtang gave first. This matter was originally designed by them, so it would be okay to let him go.

After all, it would be no good for them to investigate deeply, and it would be bad if they were caught.
