These iron coins are still made of copper coin molds. The fluidity of molten iron is worse than copper liquid, so the quality of the money is naturally not very good. However, what Xu Ping is going to try now is the "black" process. Please ignore the quality for the time being and choose it when you show it to others.

Xu Ping directed Guo Zi to sprinkle the cast iron coins evenly in the pool. Because they had to be steamed and cooked again later, the iron coins were tied up with ropes and could be taken out at any time.

Kou Yu led a few people to the edge of the pool and looked carefully at the solution in the pool, but he couldn't see anything.

Except for Han Qi, the people present were all officials for many years. I don’t know how many strange things they had seen. They were not surprised by using medicine to treat iron coins like this. The only thing they were concerned about was how effective this method was.

There were no clocks in this era. Although Xu Ping felt that he was not used to it, he had no choice. Fortunately, several officials had tried it several times and knew the steps. They had already stood up and mastered the time.

The few people present looked at it for a while, and when they saw that Gudu in the pool was boring, they picked up a few iron coins from the ground that had been processed last time to watch. The remaining iron coins here were specially selected by Xu Ping, and their appearance was reasonable.

Since the liquidity is not as good as copper, it is not easy to cast iron coins exactly the same as copper coins. The iron coins used in Sichuan are larger and heavier than copper coins, and the main purpose is to be easy to cast.

After holding it in his hand for a while, Kou Yu threw an iron coin in his hand to the ground.

"Dang------"

The iron coins jumped on the ground, and after a few turns, they stopped.

Li Hong and Wang Weizheng hurriedly came over, picked up the iron coins on the ground and inspected them carefully, and took them to Kou Yu to discuss.

Kou Yi was not trying to make fun of it, but to see if the iron coins were strong and whether they would break if they fell to the ground.

In the second year of Chunhua of Emperor Taizong, Zhao Anyi, the younger brother of former Prime Minister Zhao Pu, requested to find craftsmen to cast iron coins in Sichuan to carefully cast iron coins. They looked very beautiful and excitedly held them in front of Emperor Taizong to inspect. As a result, in order to prove their strength, they all broke when they fell to the ground, which was very furious. Although Taizong still recognized his suggestion because of Zhao Anyi's persistence and also sent him to cast iron coins in Sichuan, they left a very bad impression on the prime ministers present at that time.

Moreover, Taizong's temper is different from others. He loves to use people with mediocre abilities and loyalty. This is why Zhao Anyi failed to get things done again and again, and he was always favored. The current emperor Zhao Zhen is not like this. Now he has just taken power and is about to do something. He must not be as ugly as Zhao Anyi in front of him.

Han Qi's official position was too low and he couldn't stand with Kou Yu and a few people. Xu Ping and Guo Zi were busy again, so he had to take two copper coins and stand aside, bumping and banging on the wall to see if it was hard.

"Change the pool—"

The officials who were looking after him shouted when they saw the time was up.

Immediately, several officials came forward, went to the edge of the pool to hold the rope and lifted the iron coins in the pool.

"Are you okay?" Kou Junnei was anxiously waiting, and they all came over excitedly.

Xu Ping said: "If you need to use it for a long time, this dish still doesn't work. You need to put it in the pool next to it and soak it again."

The officials carried the iron coins and turned to the pool next to them in an orderly manner and soaked in again.

Li Hong looked at the busy officials and said, "This black iron coin is indeed a good thing, but it is too troublesome to soak it!"

Wang Weizheng smiled and said, "It is precisely because it is easy to use, so it is so troublesome. By the way, minting money is not afraid of complicated processes, as long as it is really effective. In this way, it can also prevent the stolen casting among the people."

Kou Yu pointed to several jars on the shelf and said, "Without Deputy Envoy Xu's secret medicine, I have heard that iron coins will turn black after being cooked in water? As long as the prescription of this secret medicine is not spread, I will not be afraid of stolen casting among the people. This is the biggest benefit of black iron coins!"

Xu Ping wiped the sweat beads that oozed out of his forehead and did not interject. The principle of blackening could not be explained clearly to several people, so he could not explain the risks of folk cast iron coins. As long as the value of the iron coins is too high, there will inevitably be experts among the people who cast iron coins with fake and real ones. Folk craftsmen cannot make these kinds of alkalis Xu Ping uses now, but there are always other methods instead, such as using hot urine, which can also make the steel black. However, that kind of method cannot ensure the stability of the quality, but the purpose can be achieved by using a large number of casting and selection methods. As long as the value is high, it is fine.

When the profit reaches a certain level, some people will risk taking the risk of beheading and create countless miracles on earth. How can a mere so-called secret medicine be blocked?

For the second steaming period, the officials and craftsmen took out the iron coins from the pond and placed them on a few wooden sticks placed flat on the ground. Kou Yu led the people up to him, carefully observed the iron coins behind the place, and compared them with the iron coins in his hand.

It was not until he confirmed that it was exactly the same as the previous iron coin that Kou Ying straightened up and breathed: "Yes, although the quality of this iron coin is still flawed, it only takes a change to the procedure of minting the coin. The effectiveness of the secret medicine is unquestionable!"

Wang Weizheng and Li Hong agreed. What they were most worried about was to do something embarrassing like Xu Shen, which would not make any achievements and would make them feel uncomfortable. Since there was no problem with the craftsmanship, it could be used on a large scale.

Collecting people around him, Kou said, "Everyone, the iron coins that Mr. Xu used the new method to cast are here. In my opinion, it is no different from the black iron coins he took out a few days ago. What do you think?"

Wang Weizheng and Li Hong said together: "It's true that this method is feasible!"

Kou Yu nodded: "Since everyone thinks so, the matter will be settled. Deputy Envoy Xu went back to write a memorial, and gave it to us who came today, and named it together, and report it together, and ask for iron coins."

Xu Ping hesitated for a moment: "Master, there is no problem with casting iron coins. But it should be used in the private sector. How to exchange iron coins and copper coins, and which prefectures and counties should be distributed first?"

Kou Ying smiled and said, "No, we just report the memorials. Those things are not something that our three departments can do. At that time, the priest will come forward and the various departments will discuss the matters, so there is no need to decide now. The memorial only says that there is a new method of cast iron coins. As for how to use this new method, I will skip it and not mention it."

Seeing that Xu Ping was still confused, Kou and Wang Weizheng and Li Hong looked at each other and smiled, pulled Xu Ping aside, and whispered: "If you can't decide, don't decide for the matter. There will naturally be someone in the court to discuss it, and there will always be a way in the end. Just report the new method of cast iron coins and take the credit into your hands. Things in the court may not necessarily have a result. You have to do it step by step. You don't need to take everything on yourself. But if you do it, you must have a reward. This is why the court is an official!"

Xu Ping nodded and felt a little enlightened. In other words, Kou Yu and others couldn't explain how the new iron coins would be used in the future, so let's ignore it and take the credit for it.

Although Kou Yu has many problems, he is really good to him and is dedicated to helping him. After joining the Third Division, it is his luck to have such a boss. He has blocked countless troubles in front of him and is not greedy for me, so that he can do something safely. Since Kou Yu has this intention, he should make some achievements over the years and cannot let him down.
