Li Chengqian took two steps back and left the old man for a distance before he felt a little relieved: "Father, you really can't do anything with this ten thousand guan. Think about it, is 10,000 guan enough to fight the Turks? Is 10,000 guan enough to fight the Tubo? Even if it is a disaster relief, 10,000 guan is not enough, right?"

"But you put ten thousand guan to the general as the prison, and the reward you will definitely be more than ten thousand guan. With this "cannon" attacking cities and villages is like destroying them. With this "cannon" taking the heads of the generals from a million troops is like taking objects, the Tang Dynasty no longer needs to use the lives of soldiers to face the enemy's swords and arrows. All the enemies in the world will surrender in the face of the Tang Dynasty..."

"Stop, stop, stop, don't use your trick to scare me." Li Er interrupted Li Chengqian's yy without hesitation.

In his opinion, Li Chengqian's current state is like a charlatan who wants to brainwash people. He is so awesome and brag, and he says that siege the city and the village are like destroying the dead and killing the general's head among millions of troops. Isn't this a skill in front of Lu Ban's gate?

I am really a battlefield, Bai Ding doesn’t know anything. The soldiers on the battlefield are fierce and dangerous. If you want to survive, you all depend on your life. Everything else is nonsense.

This thing called "cannon", not to mention siegeing cities and villages, even if it can reach half of the catapult, it is considered a successful weapon.

"Father, ten thousand guan is nothing to you? Otherwise... I will exchange things for you?" Li Chengqian really has no money to invest in the prison, so he can only fight with the old man in a silence.

Throughout history, no matter when, as long as it is used with weapons, no one is not expensive, and the cannon requires a lot of metal to refine.

Metal cannot fall from the sky just by saying a word. It must be dug out from the mountains, then roughly refined and transported to Chang'an, and then the government will give you the money. If you don't give the money..., the genius will sell you the metal ore you have made through a lot of hardships.

Moreover, what Li Chengqian needs now is iron ore and copper ore. These two things are strictly controlled in the Tang Dynasty. Comrade Li, who has experienced a dismissal, does not want the old man to misunderstand anything again.

If you have soldiers and money, if you do some copper ore and iron ore to smel copper and iron, you will probably not be far from your head!

It was precisely based on this idea that Li Chengqian thought of deducting some money from the old man. Anyway, he had just transported 450,000 silver from Shandong some time ago and it was not difficult for the old man to take out 10,000 taels.

Of course, there were originally 500,000 taels, but the rebate of 50,000 taels was given to Lao Yu by Li Chengqian for 30,000 to build a ship. The remaining 20,000 must be kept for the future and cannot be spent at one time.

As a result, the old man was not fooled. He almost finished speaking, saying, "Don't do this, yours is mys. Let me exchange money for your own things. Isn't your cleverness so good this time?"

"Father, only ten thousand coins!" Li Chengqian stretched out a finger, and after comparing, it seemed that he suddenly remembered something: "I have a good treasure in my hand, why don't I let you mortgage it? But the price is a little higher."

"Oh? What baby? Let me tell you, if it's right, I'll give you 20,000." Li Er knew that his son had good things in his hand, and Li Chengqian's usual things would basically not be taken seriously by him. As long as he said it was a treasure, he was basically either a lonely person or a broken seal, and was a good thing with no market value.

Li Chengqian is not that easy to cheat. He knew that as long as the old man got, he could not get it back, so he slapped: "Fifty thousand, this thing is not easy to find now. If you give it 50,000 yuan, this thing is yours."

"Then you keep it, I don't want it." Li Er said with a smile on the corner of his mouth, shook his head and said.

"Okay, Father, 40,000, 40,000?" Seeing that the business was about to be ruined, Li Chengqian took back a finger.

Pushing Li Chengqian's finger back, Li Erzhi said proudly: "Thirty thousand, look at your pitiful appearance, I will suffer some losses, otherwise your mother will say that I will take advantage of the child."

So, the third volume of "The Goddess of Luo River" that Li Chengqian had just obtained was bought by Lao Li for 30,000 yuan, and he never had a chance to be with him again.

And this was also Li Chengqian's cleverness. At the last moment, he thought of "The Goddess of Luo River". Otherwise, he would have planned to mortgage the "Preface to the Lanting Ji" at the beginning. If the thing was sold for 30,000 yuan, it would seem that he would suffer a loss no matter what.

However, although the "Lotus Goddess' Picture" only sold 30,000 yuan, Lao Li still added one. Five days later, he would watch the power of this "cannon" in the military field outside the city.

Since Li Chengqian said that there is nothing in the sky and unparalleled on the earth, its power must be extraordinary, just a semi-finished product that cannot meet the requirements in terms of distance. At most, it is better to take a look at the power of the semi-finished product.

They are all old guys who are old and old, and you can see that the whole leopard has the ability to see it.

Just like a swordsman, you don’t have to look at what the knife is made of. Just look at the materials used to make the knife, and you will know whether the knife you create will be in hand, how sharp will it be, and whether it is suitable for fighting.

This kind of thing is naturally irresistible for Li Chengqian. Anyway, the "cannon" tube is ready-made and can be used to fight it with gunpowder. However, because the materials are not up to standard, the gunpowder will not be installed, so the distance does not meet his ideal requirements.

"Chengqian, are you sure that the 'cannon' is really like you said? But don't lose my face at that time. You have to know that in five days, I will invite veteran generals in the army to see it together." In the Ganlu Palace, Li Er looked at the "Lotus God Picture Fu" spread on the table and asked Li Chengqian for the third time.

"Don't worry, my father, there is no problem, but there are still some problems with the distance of the 'cannon'. Before there is good materials, you can only get a very close distance." Li Chengqian gave the old man a shot in advance, and he was afraid that the old man would say that he would not tell the truth, or deceive the emperor or something.

"How do you plan to spend your 30,000 jin? Don't tell me that you have to buy iron ore. Although you dare not dig that thing yourself, if you transfer some from your uncle, Wuji will never report it to me within 100,000 jin." Li Er knew that his son was still relatively reliable in major events. After hearing his answer, he stopped asking questions and instead focused on the topic of money.

"A half of this money is planned to offer a reward of all over the country. As long as you can come up with a good solution or come up with a better steel formula, the maximum reward is 5,000 guan and the minimum reward is 1,000 guan! Erchen believes that there must be brave men under the rewards of the public!"
