Liu Che once said that Liu Juhui would be a good monarch, and he never had the slightest doubt about this.

Liu Che also told Liu that I have fought all the battles you should fight in this life, and you just need to be your Taiping monarch.

When I first heard this sentence, I felt that Liu Che was a little too domineering, and he always liked to use physical means to solve everything.

can carefully recall the deep meaning of this passage, and you will understand that this is actually Liu Che's helpless move.

After fighting for so many years, doesn't Liu Che know what the actual situation in China is?

There were riots and protests in various places, and he really didn't notice it at all?

If there is no more evidence to prove it, there may be a question mark, but Liu Che likes to cruise around, so it is impossible for him to completely decouple from the people, and he must be clear about the real situation.

If it's clear, then why just go to war?

Putting all the problems together, the passage that Liu Che told Liu Ju is the real reason.

Liu Ju is too stable in his actions, which is a great good thing for the people and officials, but it may not be a good thing for Liu Che to spend his whole life and for the advantages that countless people have used their lives to fight.

The Xiongnu have not been destroyed, and the Western Regions have repeatedly jumped horizontally, how can they enter Kuma and put Nanshan with swords and guns?

Liu Che can accept night and night singing, can accept singing and dancing, and can accept their ideal life.

But he could not accept that one day, the butcher's knife of the Xiongnu would be placed on the neck of the Han people again.

So he's going to fight, he's going to fight.

Even if there are all kinds of bad signs in the country, even if the population is declining rapidly, and even if grain production is constantly decreasing, he will still fight it.

He must completely wipe out the Xiongnu and completely sweep away the Xiongnu in his lifetime, so that they will no longer be able to pose any threat to the Han for decades, centuries, or even longer in the future.

This kind of thing may not be easy to explain, but putting aside the identity of the emperor and looking at this matter as a father and son, everything will be logical.

It's not that Liu Che can't accept peace, nor does he can't accept recuperation, what he can't accept is infinite peace, unlimited recuperation.

He couldn't stop for too long, because he was afraid that if he stopped for a long time, he would make the world accustomed to peace and no longer adapt to war.

On the other hand, Liu Ponu is different, although Liu Ponu's proposition is not to fight, but the same proposition, different people say it, and the effect is absolutely different for Liu Che.

Liu Ponu is a poisonous snake hidden in the shadows, he will make you paralyzed and complacent, and then suddenly give you the most fatal blow when you are most relaxed.

Although Liu Ponu said that he would not fight, his body was still very honest, and every move he made was to be able to fight harder in the future.

Didn't someone always say that fighting a war costs people and money, and there are too many deaths?

The most people died were these conscripts in charge of transportation, they had to transport food to the front, and they had to use the fastest speed on the way, and consume the least amount of food, in these conditions, they were overloaded almost every day, and the weaker ones were likely not able to survive a single trip.

Even if you are in good health, just a few trips like this will drag your body down.

But now, Liu Ponu has solved this biggest problem with a tractor, avoiding the impact of the war on domestic agriculture and economy to the greatest extent.

"The Reborn Financial Giant"

Liu Ponu's three five-year plans allowed Liu Che to see his far-reaching vision, let him see the hope for the future, and gradually calmed down the increasingly irritable war mood in his heart.

The tractor is still running round and round, living a simple life of sunrise and daily rest.

It's summer now, and except for some preparations, I can run for about six to seven hours a day, and when it's about 300 miles a day, it's about 350 miles a day, and it's 350 miles when it's more, and it's all load tests.

Now no one doubts whether the tractor will work at all, and the new focus has shifted to how long the tractor will last?

After nearly half a month of testing, they couldn't help but be stunned when they added up the mileage that this tractor had run, in terms of mileage, it had been able to run from Chang'an to any corner of Dahan.

But that's not enough!

The later test trained a few Yulin soldiers to be drivers, anyway, the speed is not fast, and there are no technical difficulties, and after learning to run a few laps, they slowly mastered the skills.

Liu Ponu put forward new suggestions for improvement, and the team once again returned to Liu Ponu's small courtyard to make improvements according to the new opinions and the problems that have been shown so far, and plan to launch Experiment No. 2 as soon as possible.

The body shape of test No. 2 is exactly the same as that of No. 1, and the exhaust system has been greatly improved, from the original large mouth directly into a finger-thick hollow pipe, the pipe is directly facing the sky, and a ball valve is added in the middle to control, as for the ball valve is not standard, this is not too important for the time being.

When the engine is running, the internal heat will rush directly to the ball valve along the pipe, and when the ball valve is closed, the heat inside and outside will hold the ball valve to death, even if there is a leakage, it is very slight, and it is not very important in front of such a large volume.

The second is to change the combustion chamber and heating pipes, which were all iron, but iron is not the best thermal conductive material, and also consider heat insulation, which can not only save fuel, but also improve efficiency.

Of course, another new technology is also starting to be on the agenda, the insulation of the front and back of the catheter.

These are all opinions put forward by Liu Ponu, and I didn't expect them to study them all in one go, but they are always in the direction.

However, reality quickly gave Liu Ponu a slap in the face, and also poured cold water on everyone's enthusiasm.

The combustion chamber adopts the design of the iron smelting furnace lining, so that it can retain the heat to the greatest extent, and at the same time can also improve the internal heat, plus the re-planning layout, so that the coal can be fully heated to any part, and the double impact of the flame and hot gas can make it heat up faster and increase the pressure difference between inside and outside.

However, after a few days of use, when I checked it according to the usual practice, I found that the shape of the heat pipe had changed slightly, and although it did not melt the iron heat pipe into molten iron, it would aggravate the failure if it was used for a long time.

Although they knew where the problem was, there was no good way to deal with it.

The efficiency has indeed increased, and even the speed has increased a bit, but the problem is that the staying power is worse.

They want machines that can work all the time without breaking, not machines that can break down quickly.

Liu Ponu, who was personally formulating a five-year plan, had to stop his plan after hearing the report, and his plan could not be carried out without a stable engine as support.

"Two ideas, by controlling the amount of charcoal added, or the charcoal into powder, adding loess to mix and then use, in this way to control the temperature drop in the furnace, or to find a new material with a higher melting point...... Liu Ponu thought about it, and finally did not say the third way.

It may be better to use steam, and the temperature is easier to keep consistent, but steam is so unfriendly to iron that it won't take long to be scrapped.

This can be seen in their first steam engine, which is now covered in rust.

"Forget it, let's do it casually first, if it doesn't work, let's change the first version of the exhaust system and use it!" Liu Ponu shook his head, gave a simple reply, and then continued to be busy with his own affairs.

The material of the engine is not a simple problem, nor can it be solved in a day or two, Liu Ponu can only find the best one from the existing materials, and the others can only be done slowly.

The five-year plan is also not as simple as it seems, it involves how much production needs to be increased in each department of the mining area, and how much manpower is needed to be responsible.

This is the first major project that Liu Ponu is really responsible for, and it is also a project related to the country.

He can just say a rough idea and let the people below have a headache by themselves, but that's not Liu Ponu's style, if you don't do it, you won't do it, if you do, then stop everyone at once, let them know that they don't understand anything, and even they understand what they don't understand.

Only by showing their real strength will they not dare to play with themselves at will in the next mission.

In other words, if you work hard for a few days now, you will be able to easily spend your life in the future, and Liu Ponu is still very willing to do this kind of cost-effective business.

"Wang Wu?" Liu Ponu suddenly remembered that he didn't seem to have seen Wang Wu for many days, and couldn't help but scream in the air.

"King, the general has been on a mission these days, ...... came out to answer, but it was not Wang Wu who answered.

Liu Ponu was slightly puzzled, but he didn't ask more, and now the only people in the entire Weiyang Palace who can command Wang Wu are Liu Che and himself.

Since he went to Lantian by himself, Liu Che has never commanded Wang Wu much, and Wang Wu has completely become his personal bodyguard, after suffering the last loss, Liu Ponu knew that Liu Che should have arranged a task for him, so he was too lazy to ask more, so as not to harm the innocent again.

Of course, Liu Ponu, who had been bored at home, did not notice the changes in the outside world, and Liu Che did not urge him again after knowing that Liu Ponu was making a five-year plan.

It seems that everything is peaceful, but in fact......

Chang'an City, inside a private house!

Wang Wu, who has always shown the appearance of an indifferent follower, has shown his indifference more perfectly at this moment.

With a big sword on his waist, he stood elegantly in the door, looking at several men, women and children in the courtyard with blank faces with leisurely faces.

From the outside, this is a normal ordinary family, and there is no abnormality at all, and even the surrounding neighbors can't see any abnormality.

However, Wang Wu still stood there steadily, followed by dozens of burly men who also had big swords pinned to their waists.

"Your Excellency, ...... What are you...... Is it a mistake? An old man in the courtyard looked at Wang Wu with a confused expression, and couldn't help but tremble.

"That's right, you know in your own heart, are you obediently going with me? Or are you going to take the lives of these people in the courtyard and then come with me? ”

The old man's face turned pale in an instant and said, "I'll go with you......"
