Under the demonstration of the old technician, Liu Ponu finally saw the so-called reversing system.

Although it still requires manpower to assist the left, this version has evolved to the point where it does not require a person to go down to the ground to push the vehicle to provide the initial power.

They added a gear next to it, and then used the principle of a lever to operate, and when they needed to move forward, they put it on and move it forward, and when they needed to move it backwards, they pulled it backwards.

The characteristics of Stirling's engine dictate that he didn't need much initial power, all he needed was a direction to guide him, and the rest was left to heat.

One engine and two engines didn't have much impact on Liu Ponu.

He doesn't mind how many resources are spent on one car, even if Dahan's current productivity is limited, hundreds of thousands of cars can still be raised.

He was more concerned about the cost of maintaining consumption, because the experts designed the two engines together, using the same combustion chamber, to achieve the greatest possible fuel savings and increase power performance.

Of course, in order to meet the needs of the army, the appearance and layout are completely different from the previous walk-behind tractors.

Now just the front of the car has become a three-axle, the front is a steering wheel without any power, using the mode of a walk-behind tractor, and the back is two wheels about one meter five apart, from the top of the front of the car, to the tail of the front of the car, the length is close to four meters in length.

At Liu Ponu's suggestion, a car is very spiritually divided into three car bodies that can be completely separated, the non-powered head, the power car, and the carriage.

Although the crawler type is very efficient, it is too resource-intensive to manufacture, and the speed is somewhat unable to keep up with the large army, so only a few are manufactured for support.

The separate setting of the power car is that when a strong power output is needed such as climbing, two or three power vehicles can be connected together, and multiple power vehicles can output power at the same time to ensure that special terrain such as climbing can be completed.

So Liu Ponu waved his hand and immediately decided to build 200 such four-wheel drive system tractors.

……

Two months later, Liu Ponu's recent life has been very miserable.

Now he rarely even goes to his own small yard, and all scientific research projects are completely free-range, and there is only one requirement for the people inside, as long as he is not idle, he can do whatever he likes.

If you want to study, you can study, if you want to study, no one cares about you even if it is interprofessional, but the premise is that you must learn something, and you must convince the management officer, so that he thinks that it is useful for you to learn these things, the kind of simple people who want to mess around, sorry, although Liu Ponu is a rich man, he is not a fool, where did he come from.

In the past two months, some people have come and some have left, although there are more people and fewer people left, and Liu Ponu's small Zhuangzi has gradually reached the scale of thousands of people, and all kinds of talents are still coming from all over the world.

"The place outside the city is no longer enough, the Zhuangzi are all good arable land, and there was no way to occupy some places to build houses before, but now it is not good, the scale will only get bigger and bigger in the future, and the arable land will be occupied more and more, you can allocate me another piece of wasteland, it is best to be the kind of land that is not very good for growing food, and it is not far from Chang'an......" Liu Ponu found Liu Che, although his Zhuangzi was enough, but he didn't want to encroach on the cultivated land too much.

Even though all the land was his, it didn't matter if he took it all, and no one could control him.

But after living in this era for a few years, Liu Ponu has gradually been assimilated by this era, and whenever he sees the high-quality arable land being abandoned or occupied, he will feel heartache.

"It's where Jianzhang Palace is next to Weiyang Palace, you can find a place to go by yourself!" Liu Che agreed to Liu Ponu's request without thinking about it, and even directly assigned the new address to the Jianzhang Palace.

The current Jianzhang Palace has not yet begun to be built, and there are only a few palaces in it, and the rest are large areas of primitive style.

Liu Che likes it more here, and he always hunts here when he has nothing to do on weekdays.

And in the past few months, Liu Ponu has also used his actions to make Liu Che realize the importance of the so-called scientific research institute.

Looking at one after another equipment and technologies that had never been mentioned by Liu Ponu, but suddenly came out of nowhere, constantly improving and enriching the strike methods of the troops, Liu Che even gradually believed the picture that Liu Ponu had painted for himself.

"But don't you think your research institute is a bit too messy?" Liu Che reminded with concern on his face.

"It's not normal!" Liu Ponu looked at Liu Che with a big grin, and immediately explained: "The scientific research institute has just been established, and everyone is the first time for this matter, and they don't know anything about technology or anything. ”

"But now it's different, after more than half a year of training, the first batch of people has basically been honed, and this time I plan to change places with this consideration!"

"When the time comes, the scientific research institute will be divided into two institutes, the inner institute is composed of the first batch of old people, who are responsible for continuing to study the latest technology, and the outer institute is responsible for some old people, and all the new arrivals are concentrated in the outer institute to study, of course, it is not half a year ago, and there is no need for them to look at the real thing and grope for learning, the old people in the institute can make up some basic knowledge books for them to learn, although those things are simple, but let them explore by themselves, it will take half a year to say less."

"And with the help of the experience of these old people, maybe it only takes three months to complete the road that the old man took half a year to complete, and the external institute conducts regular assessments, and after passing the assessment, he will enter the internal institute, and at the same time, for the sake of technical confidentiality, the external institute will also conduct detailed classification."

"You can only learn the most primitive technology when you just come, you can learn the next generation of technology after passing the assessment, and if you don't pass the assessment, you will be given two more chances, and if you don't pass the three chances, then you will go back to your hometown and enter the workshop, and those who pass will go up in this way, and the specific division of how many grades will be decided according to the actual situation!" Liu Ponu told the truth about his arrangement.

There must always be a gradual process in everything, and when you have nothing, all rules and regulations are fictitious.

When you have the foundation, it makes sense to make some rules and regulations.

As for whether those old people will be willing to compile their experiences and insights into a book for people to learn from, whether it is Liu Ponu or Liu Che, they are not worried at all.

As long as there is no technology that advances by leaps and bounds, and there are no natural disasters and man-made disasters, this technology can make your children and grandchildren have a life of food and clothing for several generations, or even dozens of generations.

But in the scientific research institute, everything they did was given by Liu Ponu, and they didn't know anything when they came, although they studied it themselves, but all the food and drink were Liu Ponu's, and Liu Ponu instructed them if they didn't understand anything.

In addition, under the guidance of Liu Ponu, the discussion of technology among colleagues has gradually become more frequent, so in the eyes of most people, they are just working for Liu Ponu, and these technologies are all Liu Ponu's.

Although Liu Ponu would make people a little unhappy to let them hand it over, they still didn't dare not hand it over.

"You......" Seeing that Liu Ponu thought things through so thoughtfully, his worries were obviously superfluous, Liu Che suddenly felt a sense of loss in his heart, but he still pointed at Liu Ponu with a smile and continued: "You are still the same as before, so that I really can't find fault with it!" ”

"I'm called steady when it's time to be stable, and no one can stop it when it's time to be reckless, isn't it a surprise? Are you satisfied? Isn't it time to ......" Liu Ponu smiled, deliberately prolonging his tone.

He doesn't count on Zen or anything, and it's useless to say that he is counting on it.

Liu Che, a bad old man, is just a matter of saying, Liu Ponu felt that the only thing he could do was to make him happy, and then clean up the people who should be cleaned up, so as not to let the witch curse happen again, and then be safe and steady, just wait for the successor honestly.

Well, don't count on it, but you still have to stimulate this bad old man when it's time to stimulate it, so as not to let this bad old man float up after a long time.

"Hehe, you kid knows what good things can't come out of your mouth!" Liu Che also smiled.

Although it is impossible to give up now, Liu Ponu didn't mention it for a few months, and Liu Che always felt as if something was missing in his life.

And Liu Ponu mentioned this matter, which made Liu Che find the pleasure that he had not seen for a long time, and the refreshing feeling that you pit me and I pit you seems to be back.

"Do you think I won't?"

"Then you guessed wrong!"

"Although I don't plan to give it to you now, I can let you experience what it is like to be an emperor first!" Liu Che looked at Liu Ponu with a sly look and quipped.

"Cut ......" Liu Ponu looked disdainful, and said: "You have said this eight hundred times, my ears are almost calloused, what does it feel like to be an emperor?" It's not that I haven't experienced it, isn't it just to pick out some not-so-important government affairs and let me deal with them directly without going through your hands, even if I don't participate in this work, the three provinces can solve it themselves! ”

Hearing Liu Ponu's complaint, Liu Che laughed very unkindly.

I did say this, and I did do it, but the conscience of heaven and earth, didn't I do this to train you kid?

What if you go straight to the big things without even dealing with the less important things, what if something goes wrong?

Although the system of the three provinces is to reduce the probability of error, it is only theoretical, and most of the time it is based on the emperor's will, unless the three provinces can really convince the emperor to change his mind.

It's not that kind of thing doesn't happen, it's not impossible, it's just that the probability is relatively small.

"This time is different, I plan to go to Yangzhou after the New Year, and then go around the surroundings by the way, this time it will be as short as half a year, and as long as a year, I will leave all the matters inside and outside the court to you to deal with......" Liu Che smiled, but his eyes looked at Liu Ponu extremely sharply.

According to his previous character, Liu Che had already gone out shopping, and since he found Liu Ponu, Liu Che hadn't gone out for two years, which almost suffocated Liu Che.

In the past, it was customary for Liu Che to go out with the prime minister and others, and the prince stayed in Chang'an to supervise the country, dealing with some ordinary things, and when he encountered important things, he needed to report to the emperor to deal with them.

But this time, looking at Liu Ponu, who was almost unable to find fault, Liu Che planned to try to let go.

Liu Che's boldness comes from the changes in Dahan in the past two years, although he doesn't want to admit it, but he has to admit that Dahan has become more and more stable in the past two years, so the possibility of chaos is not great.

"What about military power?" Liu Ponu smiled, an emperor who has no military power? It's an experience, but don't you bad old man just want me to work for you for nothing?

Why do you a bad old man go out to play in the mountains and rivers and scourge the yellow flower girl everywhere, and I, a good boy in the middle of spring, have to stay in Chang'an and work overtime to die? I don't pay overtime!

Although Liu Ponu did not expect Liu Che to give him military power, even if it was his nominal 20,000 new troops, Liu Ponu only had the power to train and supervise, and did not have the actual power to mobilize.

Liu Che squinted his eyes slightly, as if he was thinking about something, and after a long time, he spoke: "I promise you 100,000 soldiers......
