After Li Jin left, Chu Qing felt uneasy. Sooner or later, his iron products would enter the market, so even if Li Jin was sent away, wouldn't others covet this technology? What if it was a bigger official? What if someone instigated it?

Should the emperor directly take it back to the state?

You can't keep this skill by yourself. What you have to do now is to hand it in voluntarily, and maybe you can receive some honorary or financial rewards. Otherwise, you are really afraid of getting into trouble, and you and Xiaobao are not safe!

Three days later, Chu Qing brought the Xiuchundao - yes, the Xiuchundao. Chu Qing's understanding of the Secret Investigation Department was the Jinyiwei of the Ming Dynasty, but it was not as bad as the Jinyiwei.

Chu Qing went to Zhoucheng with a newly made Xiuchun Dao, an improved dagger, a few small steel ingots, and two copies of the same drawings.

First, he went to the secret reconnaissance department's office in Jizhou and found the person in charge. He handed over an envelope containing drawings and reporting materials, explained his purpose, and also presented two weapons. Chu Qing wrote down the facts basically truthfully.

It’s in the reporting materials.

He did not directly say that the Yubu officials were robbing them, but he only said that he thought that since the Yubu doctor said that this thing would be beneficial to the country and the people, he should not take other people's money. But he was also afraid that the blast furnace would pose safety risks, so he asked the Secret Investigation Department for instructions on this drawing.

It has been handed over to the magistrate of Jizhou to see if doing so violates the regulations of the Secret Investigation Department. At the same time, a sample knife was sent and asked if the Secret Investigation Department needed it.

He went to Jizhou Prefectural Government Office again, met Song Tingshan, explained his purpose of coming, and put samples of steel ingots on the table. Song Tingshan played with the steel ingots and listened to Chu Qing's words.

He figured out what Chu Qing meant. Someone wanted to take credit for this technology and use it for themselves. Don't tell me, this is really a way.

According to Chu Qing, ore can be melted into molten iron in one day, and a handful of finished products can be produced in three days. So if there are enough blacksmiths and enough blast furnaces, can ironware be mass-produced quickly?

Regardless of whether it is for military or civilian use, as long as this technology is popularized, it will push the Daxuan Kingdom forward. Who doesn't want this credit? Li Jin of the Yu Department is not small in ambition.

"Master Song, if this is really beneficial to the people and the country, then can we ask for money? I can't bear it in my conscience." Chu Qing concluded.

"Here are the drawings, as well as instructions for use and an introduction to the amount of iron produced. Take a look. If it works, you can give it directly to the court, free of charge." Chu Qing looked simple.

"Master Li came to send money. I didn't ask for it, and I didn't know what to do. I sent a letter to the Secret Investigation Department to ask, but I haven't received a reply yet. I couldn't wait any longer, so I came to see you." Chu Qing added.

Song Tingshan smiled, he was just trying to protect himself. But this thing is really good and should be reported to the court. As Li Jin said, it is really beneficial to the country and the people.

"Don't worry, Mrs. Chu, I will write the memorial right away and report it urgently." Song Tingshan promised.

Chu Qing returned home, feeling relieved. Since this was something he couldn't keep, he wouldn't keep it. But if he wanted to give it out, he had to give it to the highest-ranking person - the emperor.

Moreover, several aspects of this matter are already known, including the state government, the Secret Investigation Department, and the Yu Department. No one can covet him. Even if he is the emperor, his appearance should not be too ugly.

As soon as he felt relaxed, he ran to see Master Lu. During these days, Xiaobao followed Master Lu wherever he went. He no longer followed Chu Qing out to visit.

When Master Lu was forging iron, he followed and watched, and even stuffed cotton balls into his ears. Xiaobao was fascinated by turning such a hard iron lump into a weapon, and came to watch "The Metamorphosis of Iron Tuo Tuo" every day.

Chu Qing bought a lot of snacks from Zhoucheng. When he came back, he put some of them into the small paper bags with emoticons he made, and then picked out the soft and not so sweet ones and put them on the plates. Now he came to the iron room with a large tray in his hands.

.

He put several plates of snacks on the table and asked someone to make tea. Chu Qing was about to discuss things with Master Lu. Xiaobao sat by himself and stuffed the emoticon snacks into his pocket.

"Mr. Lu, the steel ingots we have now don't have to be forged for a long time. They are only forged to create shapes. Look, if we make some molds, pour them directly with molten steel, and then polish and trim them, would that work?" Chu Qing

Ideas were proposed.

"Well, I've been thinking about this for the past few days," Mr. Lu said. "I also want to try this, but... farm tools can do this, but cooking utensils, such as iron pots, are difficult, right?" Lu

The gentleman frowned and said, "If I cast it into a steel plate and then knock it out into a pot shape, I'm afraid it wouldn't be time-saving."

Chu Qing also frowned and thought. Xiaobao was peeling melon seeds next to him and put the melon seed kernels on Chu Qing's plate. Xiaobao has gained strength recently and no longer bites the shells with his teeth. He crossed his thumbs with his two little hands like this

Press it down repeatedly and the melon seed shell will crack.

Xiaobao stacked the halves of the melon seed shells like a stack of plates. There were already several bunches stacked on the small table, which was neat and space-saving. What a great idea! Xiaobao is a big koi!

Chu Qing picked up Xiaobao and kissed him loudly.

"Mr. Lu, look at this," Chu Qing picked up Xiaobao's melon seed shells, "Pack these two together, with molten steel in the middle... Let's bake some molds like making No. 3 bricks."

Mr. Lu held the melon seed shell and looked at it: "This is a good idea. I heard my master say that they also thought about using this method to make iron pots at that time, but they failed. The smelted iron slurry is not easy to thin after cooling.

It still cracked. So I always used red-hot iron to forge it into a cake and then shape it."

"But our steel is different. I have hammered it these days and found that the toughness of this steel is no worse than wrought iron, and its solidity is better than that of smelted steel. So, I think your method can work."

Just do it. Master Lu got up and was about to go to work. However, he remembered something and turned around and asked: "Mrs. Chu, look, some of the steel outside is called Hundred Refining, some are called Thirty-three Refining, and some are called Fifty Refining."

Shouldn’t ours of the Sixth Level also have a name?”

Chu Qing thought for a while: "Let's call it 'Baosteel No. 1'!"

The mold is not that easy to make. Master Lu led the workers to mix the mud, wrap it in a large inverted iron pot, and use a wooden strip cut into the curvature of the bottom of the pot to scrape the mold inch by inch to make it

Even and smooth.

Master Lu made a batch of different types of mold embryos based on the existing iron pots. Chu Qing took out the horse spoon he used and let them be used to make molds.

Master Lu said that a mold can be used for up to four or five days, so this mold will have to be made continuously in the future.

"I thought about it, we not only have to make steel pots, but also iron pots. Ordinary people may not be able to afford steel pots. If our approach is successful, the iron pots will be much cheaper than outside. The price of iron pots outside is,

The handiwork costs a lot of money," Master Lu said.

This is true, Chu Qing has not thought of this. Once something can be mass-produced, it will indeed be much cheaper. In addition to selling bricks, selling iron pots is also a way to make money.

Chu Qing doesn't have much money now. Not to mention providing bricks to the government and earning 8,000 taels, but after deducting the money provided to others, material fees, and workers' wages, there is basically less than 4,000 taels left. And she

There are still twenty servants that the long-term workers have to support.

Besides, it was a one-time deal, and you had to make a long-term living in the future.
