"Do I look like a fool?" Liu Che looked at Liu Ponu with disdain.

A thousand?

Give him another year?

Break through Chang'an City?

Penetrate Weiyang Palace?

Want to eat fart, right?

With this little person, I'm afraid that he will be defeated before he gets close to Chang'an City.

Although Liu Che knew that Liu Ponu could always make something new, Liu Che still didn't believe it in this matter.

The basic common sense is there, even if Liu Che is willing to make bold assumptions, he really can't think of how Liu Ponu can get a thousand people to do this.

"This is Chang'an, not an endless grassland!" Liu Che continued angrily.

"Bad old man, I'm afraid you haven't really realized that the times are different anymore......" Liu Ponu looked into the distance with a relaxed face.

"What's different?" Liu Che still asked in disbelief.

How long has it been?

The development of the Han Dynasty in the past year has indeed been very fast, and the development in the next few years will also be very fast, but no matter how it develops, it is nothing more than a substantial increase in agricultural output, and the army's equipment can be quickly upgraded, from copper weapons to iron weapons.

In addition, the infantry is still the infantry, the cavalry is still the cavalry, and the people are still the people.

The only difference may be that with the massive use of tractors, more conscriptions can be avoided in the future, so that these conscripts who should have been conscripted can stay at home to continue to produce, continue to create people, and continue to make the population of the Han Dynasty expand rapidly.

"The use of tractors is not just about plowing land and transporting...... Liu Ponu reminded lightly.

Liu Che didn't expect this, but Liu Ponu didn't feel strange at all.

Historically, the steam engine has been around for so long and no one has thought about making a tank armored car or something, although it is indeed not suitable to use a steam engine, but no matter how inappropriate, it is better than relying on human flesh to pile up, right?

The engine is small and the power is insufficient?

No problem, the attack power of this year is just like that, the big yellow crossbow is the strongest individual ranged weapon, and there are catapults or something, but if you use it against vehicles, the hit rate will be a problem.

So now if Liu Ponu wants to play with armored cars, he doesn't need to make too thick armor at all, as long as the inside and outside are covered with a layer of iron sheets, and the middle is directly filled with hard wood.

While talking, the two came to Liu Ponu's courtyard.

The courtyard is still a busy scene, full of people studying engines, although Liu Ponu helped them point out the direction, but for them without any experience, it is still difficult to continue research.

For this situation, Liu Ponu can only say that he can't do anything, that's all he can do with his own ability, and if he continues, he is afraid that he will fall off the altar.

Of course, scientific research can't help, but in the system, Liu Ponu can help them.

For example, if different projects are assigned to researchers, and the researchers of each project only need to be responsible for researching the project they are responsible for, and then everyone meets once a day to express their opinions on their own research and problems, and then anyone can put forward their own ideas and suggestions, maybe a word of unintentional words can solve a big problem?

Liu Ponu walked straight to his hut, took out some finished gunpowder from the wooden box, and came to the outside of the house.

"What's this black thing?" Looking at the black powder in Liu Ponu's hand, Liu Che couldn't help frowning.

Carboniferous?

It's not like ah, he's seen coal, it's not like this at all.

"This is what can change the pattern of war!" Liu Ponu smiled slightly, and directly put the gunpowder in his hand in an open place, and let people find the source of fire.

Then the ignition source was thrown directly on the gunpowder.

With a bang, the gunpowder was ignited instantly, and a blinding burst of fire and a huge burst of black smoke appeared.

Liu Che was taken aback by this sudden scene, and his eyes stared at the remaining traces of gunpowder on the ground.

What does he seem to know?

But they don't seem to know anything......

Gunpowder is not only a novelty for Liu Che, but also for everyone.

Although this thing was invented by Huaxia, Huaxia did not continue to study this area for hundreds of years.

During this period, 99 percent of the use of gunpowder in China was in artillery warfare, and the military application was negligible.

After gunpowder was transmitted to Europe, in a short period of time, Europe surpassed China in gunpowder technology in an all-round way.

Just ask you if you're angry?

At the beginning, the ratio of gunpowder was 1:1 for nitrate and sulfur, and gradually changed to 2:1 or even 3:1 in the Song Dynasty, and different auxiliary materials were added to help burn, release poison and so on.

The advantages of Liu Ponu's traverser are once again reflected here, the power of gunpowder depends on the proportion of nitrate, so at the beginning of the fight, Liu Ponu configured it according to the most reliable ratio he could find.

I haven't had time to test the effect of the explosion, but Liu Ponu is not in a hurry, as long as the method is right, the effect will definitely not be bad.

Liu Ponu didn't continue the demonstration, he wanted to leave Liu Che with some surprises, he couldn't take out all the good things in one go, right?

"You're too disrespectful here......" Liu Che glanced at the small courtyard that was not too big.

His original intention was to let Liu Ponu live here to show how much he valued him, but who would have thought that this kid would bring a large number of craftsmen over.

The good Weiyang Palace has become a blacksmith shop in an instant, and it is okay to jingle all day long.

But in order to facilitate the construction of materials, not only a smelting furnace was set up here, but even some blacksmith iron-making equipment was also purchased.

"I'll find you another place to live......" Liu Che sighed helplessly.

"Father, don't bother, it's good to live here, any problems can be solved at any time, it's very convenient!" Liu Ponu hurriedly shook his head and changed places, doesn't that mean that he will have to run away more in the future?

"Convenient for what? You're the crown prince now, and you're in a place where you can't even find your feet, so you let those subordinate officials stay there? Liu Che's face turned dark, and he didn't have a good air.

This kid is good, but it's also a headache.

There is really nothing to say about what has been researched, but this gunpowder, which cannot be said to be good or bad, cannot be evaluated for the time being.

But this kid is really stubborn, and he can lock himself up for a few months when he encounters research things.

It didn't matter when he was the king of Shu, but not now.

As a crown prince, how can he lock himself up and study those things that he doesn't know about for months?

If Liu Ponu was allowed to continue like this, he would not have to be the crown prince, and the country would have been in chaos a long time ago.

No, we have to cure this kid's stinky disease.

What is it for a prince to think about how to govern the country, but to study these things every day?

Although Liu Che also admitted that what Liu Ponu made was very useful, that was not the reason why he put all his energy on it.

"You are the crown prince, sooner or later I will hand over this empire into your hands, the most important thing you should do now is to learn how to manage this empire well, you are smarter than Liu Ju, and it is easier for you to accept the reality than him, I will not stop you from engaging in these things, even if you want those people in the workshop to get official status, I will not stop you, even if you want to work against everyone in the world, I will still support you, but you must understand that you must first ensure that you can completely control this empire, and then you can do what you want to do!" Liu Che said with a solemn expression.

Liu Ponu's enthusiasm for research has only recently been shown, but Liu Che does not regret making this choice.

Because he knows very well that Liu Ponu can distinguish between the important and the important, and now he just mistakenly regards the things in front of him as the most important thing.

And what he has to do as a father is to correct his concept and let him return to the right path.

Liu Ponu glanced at Liu Che with a slight hesitation.

He could understand Liu Che's intentions, and he could also understand Liu Che's feelings.

But give up gunpowder, can you accept it yourself?

"I did this thing just to prepare for a tough control of this empire!" Liu Ponu felt that he couldn't accept giving up gunpowder, even if Liu Che didn't let himself give up.

"Are you going to take this thing so that the whole world will be afraid of you and submit to you? Don't be naïve, your credit is enough for them to admire, all you have to do now is to calm down and consolidate what you have done before! I didn't say I wouldn't let you do this, can't I let someone else do it? Why do you have to leave everything behind to do this? Liu Che was stunned for a moment, he still didn't understand what gunpowder could do, but he saw that Liu Ponu did not intend to back down on this matter.

This just became a prince's wings hard?

Although this product has not been soft, it still makes Liu Che a little uncomfortable for a while.

"Li Guangli's expedition to Dawan is doomed to failure, soon, at the end of the year, and slowly at the end of next year, the court will receive the news, and you will definitely be furious at that time, and when the Huns receive the news, they will definitely launch a provocation against the Han Dynasty, you will not allow this to happen, and I will not allow it either."

"But what if it's not allowed? Sending hundreds of thousands of troops on an expedition to the Western Regions? That's a good idea, but where does the food come from? ”

"Quyuan plough has just been put into operation this year, and many places outside will not be able to put it until next year at the earliest, and it will take three or five years to completely form a scale and produce a regional effect at the earliest, and this battle must be fought, but it is also very likely to hollow out the entire Han family."

"It is true that the imperial court has made some money by selling plows, but can it buy grain if there is money? The people don't have so much food at all, where can the court buy it? ”

"Internal and external troubles, the imperial court can not help but deal with it, the only way to deal with it is to reduce the number of troops, in order to reduce the burden of the war on the people, although the replacement of iron weapons can solve the problem to a certain extent, but it is far from enough, so you have to rely on this, rely on this, do you know?" Liu Ponu pointed to the traces of gunpowder remaining on the ground.

Quyuan plough covers the widest area of only Lantian County, basically reached half, in addition to Lantian County, even Jing Zhaoyin only achieved the coverage rate of less than one percent, the current production capacity can not immediately meet the huge market demand, farming he needs time, and the war just does not give you time to prepare.

Of course, the imperial court can endure it first and wait a few years to settle this account, but is Liu Che the kind of person who is willing to endure it?

Liu Ponu returned to the house alone, took about a pound of black powder, and asked people to directly move the mortar and mallet out.

A pound of black powder was directly put in, and then hit it heavily with a wooden mallet, and it didn't take much effort, and the black powder that originally occupied half of the depth of the wooden mortar was only one-third thick.

Liu Ponu used a wooden shovel to take out the smashed black powder and put it into a rag, then tied it tightly with a rope, and then shook it in front of Liu Che with a palm-sized bag of improvised explosives.

"Go to the schoolyard and I'll show you what this thing is really for......"
