Gao Ziran quickly helped him up: "Please get up quickly. General Li, please speak directly if you have anything to say."

Changsheng smiled and stretched out his hand to peel off the red cloth on the plate, revealing an iron basin inside.

Gao Ziran looked at it and saw that it was just a basin that he usually used to wash his face and feet. However, most capitals used copper basins. This was an iron basin, so it was not that unusual.

So he asked in confusion: "What does General Li mean by this?"

Changsheng picked up the basin and put it in Gao Ziran's hand: "Look carefully and see if there is any difference?"

"Isn't this just...eh?" Gao Ziran didn't take it seriously when he first took it, but when he held it in his hand, he immediately discovered the problem.

This basin is so light.

"Master Li, there is something wrong with your basin!"

There is indeed a problem with this pot. During the Sui and Tang Dynasties, copper pots were mostly used for pots, and iron pots were also used in areas rich in iron ore.

The biggest difference between the two is that iron basins are easy to rust, so they are not as durable as copper basins, so the price is lower.

In order to prevent the iron basin from rusting so quickly, some businessmen will ask craftsmen to add some other metals to play an antioxidant role, but the price will naturally be higher.

The fourth child has shown amazing talent in iron smelting since he followed Master Lu.

Especially the ratio of iron to other metals. When different types of metals are added in different amounts, the characteristics of the wrought iron obtained are different.

After constant experiments, Chang Sheng asked her for some low-quality iron that oxidizes quickly.

"Why do you want to sell this iron to the Turks?" Gao Ziran was shocked when Chang Sheng said this. This is a serious crime of confiscating the family and exterminating the family: "You privately selling iron to foreign countries is a serious crime of exterminating the Yi tribe!"

"Master Gao, don't be nervous, let me explain to you slowly!" Chang Sheng smiled and pushed Gao Ziran back into his seat.

"These iron weapons are to be sent to the Western Turks, the same ones that attacked Dunhuang last time."

Since the last attack, Xi Turk Ji's vitality has been severely weakened. Not only has the trade with the Han people been suspended, but some surrounding small tribes are also ready to take action after seeing that he was defeated.

Now, in order to suppress the various small tribes, he has begun to collect various iron tools, ranging from iron pots and basins to iron spoons and iron needles. I don't know who had the bad idea to turn these into molten iron and beat them into weapons.

Nowadays, the iron products on the border black market are fetching sky-high prices. It would be unreasonable for Changsheng not to take a part in this.

"The Turks use the iron we sold to them in the Sui Dynasty. We have already banned the sale of iron to them. The iron can be exchanged for cattle, sheep, horses and even women. This iron is specially made and weighs only wrought iron.

Two-thirds of it is mixed with a lot of sulfur. If this is used to make weapons, I guarantee that all their equipment will rust in less than two years!"

Hearing this, Gao Ziran and the two inner guards showed expressions of relief. It's okay if they don't support the enemy. If they don't support the enemy, it's not a matter of losing their heads.

Gao Ziran began to weigh the pros and cons, and Changsheng looked at him with hope. This matter was too big. If he didn't report it, if the news leaked out and someone took advantage of it, it would be a serious crime of confiscating the house.

"General Li, I think this matter is feasible. I will report this matter to the emperor later, saying that this is our deliberate method to weaken the enemy. This matter does not need to go through the cabinet and is directly submitted to the emperor." In order to earn money to buy armaments, Mr. Gao also did the same.

Fight hard.

"I suggest that you don't rush to report it now. When the time comes, you can report it to the court together with the good news." Changsheng said with a smile.

Gao Ziran was surprised and happy when he heard this: "When will there be good news? General Li, please don't make me happy!"

"Don't worry, Mr. Gao, I'll make a quick calculation and it will be within the year."
