Liu Che looked at Liu Ponu helplessly, this kid always likes to give me some problems.

"Is there any other solution besides iron and copper?"

Liu Ponu shook his head, there is no way, just use steel, the question is are you willing?

Seeing this, Liu Che couldn't help but be a little disappointed: "Copper has to be used to mint coins, and a plow has to use more than a pound of copper, and the people can't afford to use it at such a high price......"

Liu Ponu doesn't have to think about it, but Liu Che has to think about it.

It took a lot of effort to take back the coinage from the nations, and it took a lot of effort to take control of their copper mines.

Now it is impossible for the imperial court to release so much copper for agricultural tools under any circumstances, even if it is calculated according to one pound of copper, at least more than 120 new coins can be minted, and counting all kinds of miscellaneous expenses, this new plough must be sold for at least 150 yuan so that it will not lose money.

This kind of price is not to mention the people, even the powerful will feel pain, not to mention that the hardness of copper is not good, and it will be damaged if it is used too much.

"I have a way to solve it, but I don't dare to say it, and the court doesn't dare to use ......" Liu Ponu shook his head slightly.

The technical aspect is solved, and whether it can be promoted or not is not something you can control.

Fortunately, even if the Quyuan plough cannot be promoted for the time being, at least the two projects of compost and waterwheel can ensure an increase in production.

In this farming competition, the probability of winning the first place should be quite large.

"What's the solution?" Liu Che's disappointed eyes suddenly released a fine light.

"Don't worry about any way, the imperial court will not agree anyway!" Liu Ponu smiled.

It's not that he doesn't want to say it, but it's useless to say it.

Although the Han Dynasty did not deal a devastating blow to commerce, and even opened the Silk Road for commercial activities, it was an official act, exchanging luxury goods for goods from other countries.

It is a completely different thing from farming tools, and making agricultural tools from iron does not reveal iron-smelting technology.

But what the imperial court was really worried about was that after the countries had iron, they would privately engage in research and development, so as to develop their own iron weapons.

"Oops, old man, have you forgotten what I told you before?" Liu Ponu glanced at Liu Che, he was not worried about the cultivation competition, but he was very worried about this bad old man.

It's unreliable, it's so unreliable.

Since the bad old man recognized himself, except for making himself carefree in life, other aspects can be described as a mess, and he has to live a life of fear every day.

"Huh?" Liu Che was stunned, bad old man? Your name is my bad old man?

"If you continue to do this, I'm afraid it's not far from raiding your house and destroying your door......" Liu Ponu didn't care about Liu Che's reaction, and said directly to himself.

"You're alarmist!" Liu Che was trembling with anger, and he hated to give Liu Ponu two slaps, whose son dared to say this about your father like you?

"Hey......" Liu Ponu sighed helplessly.

If you find it, you will find it, and if you can't find it, you will pull it down, anyway, you are crossing, just do your best.

If you hadn't suddenly appeared and pulled me into the water, who would have bothered you?

I am happily guarding dozens of acres of land, trying to find a way to mix up my fame and avoid forced labor, and I may not be able to live a comfortable life in the future.

But I can't help it, I've been pulled into the water.

The relationship of blood relationship cannot be erased no matter what, even if he is dissatisfied with Liu Che in his heart, he still has to persuade him at this time.

It's hard to say whether it will have an effect or not, but if you don't work hard, it will definitely not have an effect.

"I told you some time ago that the emperor may have an opinion on you, so let you do things and talk more leisurely, what is the result?"

"You're good, you donated a left-handed to me to grow up, don't you just use your brain to think about it, there are suddenly so many titles in the world, and they are also obtained by donating food, what will those soldiers who are desperate on the front line think?"

"Even if the emperor doesn't have so many dirty thoughts now, can you guarantee that the emperor won't have other thoughts when he knows that the front-line soldiers are full of complaints?"

Speaking of this, Liu Ponu couldn't help but sigh again, hating iron is not steel......

"Don't think of the emperor as stupid, if he is really as stupid as you think, he won't be able to be the emperor, I heard that when the emperor was young, in order to compete for the throne, he could even say such things as Jinwu Zangjiao to coax the eldest princess, and now the emperor has made such great achievements, there is no reason to live more and more, right?"

"If I'm not mistaken, the Emperor may have already had a strategy for dealing with this when he brought it up."

"Therefore, in the next period of time, there will definitely be many upstarts in Chang'an City who will be cut down because they are too angry, and within ten years, these upstarts will basically be beaten back to their original shape, and even the emperor will take advantage of this opportunity to suppress some old nobles who don't like their eyes."

Liu Che pursed his lips, I really didn't take the initiative to think of this, didn't you kid put forward this bad idea?

But......

Taking the opportunity to suppress the old nobles who don't like it, this idea can be referred to......

"You should have other ways to increase production, right?" Liu Che changed the topic with a smile and continued: "So at most a year, your fame will become a real fame, and the whole dynasty will respect you, you are different from those people who are vegetarian in the corpse position, and the emperor still values people with real skills......"

"!" Liu Ponu immediately objected: "If the emperor hadn't taken a fancy to Empress Wei, would Wei Qing, who is a house slave, be able to ascend to the throne?" If it weren't for the emperor's support, Wei Qing would have worked hard from the grassroots level, would there still be today? Maybe if he was not careful in a battle, he would die on the spot, if Huo Qubing wasn't the emperor's nephew, could he be entrusted with a heavy responsibility at his age? ”

"Your clan sister is still the prince's concubine, and in the future, your identity will not be much different from Wei Qing and Huo Quai'......" The corners of Liu Che's mouth rose slightly, the most proud thing in his life was to promote Wei Qing and Huo Quai, although Huo Quai's illness became the biggest regret in his heart.

Liu Ponu looked at Liu Che with a heavy expression, pinning his hopes on the crown prince Liu Ju, this idea is very dangerous......

Although Liu Ponu can also understand Liu Che's thoughts, after all, if someone else, I am afraid it will be the same idea.

I have already hugged the prince's thigh, as long as I don't make a mistake of principle and send the prince to the throne steadily, isn't the rest simple?

Besides, now the prince's identity and status are so solid, his uncle is the general Wei Qing, Wei Qing said a word, the Manchu Dynasty did not dare to be presumptuous, and his mother was the queen, although he had not been very popular with the emperor in recent years, in addition to the prince, there were a group of important ministers around him, who could shake his status?

But as a traverser, Liu Ponu knew how the crown prince Liu Ju was doomed step by step, although Liu Ju only occupied 30% of the responsibility for this matter at most, but failure is failure.

Even the crown prince has been beheaded all over the house, let alone you followers?

"Bad old man, you don't really think that holding the prince's big tree is foolproof, right? If you still think so now, it's better to really listen to my advice, hurry back and resign, even if you don't want to go to Shudi and Lingnan, let's change to another place, if you really don't want to leave, why don't I give you the cultivation technology, you can find someone to hand it in, and then give me a sum of money to let me go by myself......"
