Lord: Taken away from inheritance at the beginning.

In the next two days, Ronin, accompanied by McCann and Selin, completed his inspection of Boulder City.

During this process, Luo Ning saw with his own eyes the diverse stone mines in Boulder City. If large-scale infrastructure construction is carried out in the future, this place will undoubtedly be an excellent stone mine base.

In addition to inspecting resources, Luo Ning also had a meeting with the residents of Boulder City.

Since the last turmoil, many people are still worried. After all, the lord is not coming, and they don't know what the future of Boulder City will be like.

Luo Ning's official appearance gave them a shot in the arm, letting them know that their lord was here and paying attention to it.

Two days later, Luo Ning left Boulder City and came to Chishan Town.

Although the defense and government affairs of this town are handled by McCann and Sailin, matters involving the iron mines in Chishan Town are handled by master blacksmith Feng Si.

For more than three months, the iron ore in Chishan Town has been mined day and night. Deep in the iron mine, Kalles blacksmith and others transferred from Wubei Territory have built a blast furnace for iron making. stand up.

"Sir, after our many experiments, we can now directly cast ordinary farm tools."

Feng Si took Luo Ning to visit their production base.

At this time, the blast furnace was smelting iron ore. A worker poured the red molten iron into a clay mold and cooled it to form the shape of a hoe.

To be honest, Fons was shocked when he first came into contact with this production method.

When he learned that this method came from the Lord, he felt an unprecedented admiration for Luo Ning.

However, he also discovered disadvantages when using hoes cast in this way.

"Sir, your method is indeed quick and convenient, but the cast hoe is relatively weak in hardness and can easily crack or even break during use."

The forged hoe has high hardness and long service life, but forging takes too long and costs too much;

The cast hoes last a relatively short time and are easy to break, but the production time is short and the cost is relatively low.

In Fons' view, these two methods have their own advantages and disadvantages. It is impossible to say which one is better and which one is worse. The key lies in the choice.

Luo Ning listened to Feng Si's report and nodded.

"Casting does have disadvantages in this regard, but the severity of the disadvantages can be reduced through other methods."

"Oh?"

Feng Si's eyes lit up, shining with desire for iron-making technology.

Luo Ning smiled and said, "That's heat treatment."

As he spoke, he walked to the shelf nearby, picked up a cast hoe, and threw it into the boiler.

"Through heat treatment methods such as quenching and tempering, the stress generated during the casting process can be eliminated and the grains refined, thereby improving its hardness and strength."

Feng Si looked puzzled. Although he was a master craftsman, he had never heard of these new words spoken by Luo Ning.

Ronin asked Kallus to get a bucket of water. After the hoe in the boiler had been burning red for a while, he took it out and quickly put it into the bucket filled with water.

There was a stabbing sound, and a large amount of water mist suddenly rose.

"Heating it to the right temperature and keeping it for a period of time, and then cooling it quickly, is quenching. In this way, the hardness, wear resistance, etc. can be greatly improved."

After Luo Ning finished doing this, he threw the quenched hoe into the boiler, heated it and took it out to gradually cool down.

"This is tempering, which can eliminate the stress generated during quenching, prevent deformation and cracking, and readjust the hardness and strength."

Fons, Kallus and others considered themselves to be somewhat skilled, but when they heard the words spoken by Luo Ning, they felt like three-year-old children learning the words and could not understand them at all.

"I just demonstrated the effect. Actual quenching and tempering require very high temperature control, and we need to constantly sum up experience to master it."

Luo Ning said to Feng Si and others: "How to adjust the strength of iron through heat treatment, I leave it to you."

Everyone nodded solemnly. They thought that blast furnace ironmaking was everything to the lord, but they didn't expect that the lord knew more.

However, facing Luo Ning's explanation, they were all eager to give it a try. After all, everyone wanted to be the first to eat the crab.

Next, Luo Ning stayed briefly in Chishan Town for two days. While checking the mining records of the iron mines during this period, he also needed to understand the situation in Chishan Town.

In the meantime, Philip and Thorstein, the lords of Cassirer Town and Surrey Town, learned about Luo Ning's arrival through businessmen in Chishan Town.

As vassals of Wushan Castle and friends of Luo Ning, a genius, they naturally extended the invitation.

Luo Ning did not refuse. After all, they were neighbors and it was necessary to have a good relationship.

He chose the meeting place in the town of Cassirer and met two barons.

Under Philip's warm hospitality, the three of them all ate and drank to their heart's content.

During the dinner, both Philip and Thorstein made requests to buy production tools from Ronin.

Cassirer Town is okay, but the Surrey town that has been abandoned for many years has a relatively large demand for farm tools.

Luo Ning would naturally not refuse this kind of business that came to his door.

He sells iron ore at a relatively low price. Of course, if the two of them want to buy finished products, Luo Ning can also provide it.

When they learned that Luo Ning's finished product was 30% lower than the market price, both of them rushed to see the finished product. If possible, they would definitely buy a large batch.

This is the benefit of blast furnace ironmaking and casting, which reduces production costs a lot.

Luo Ning can take advantage of this advantage to hit the existing market at a lower price and steal their business.

However, he did not promise immediate delivery, but set the time before spring next year.

During this period of time, Feng Si and others can study heat treatment technology to improve the strength of cast agricultural tools to meet the needs of daily farming.

In fact, Philip and Thorstein also have their own calculations.

They originally just wanted to buy iron ore or farm tools at a friendly price, but they didn't expect the price of Luo Ning's finished products to be so low.

The two of them summed it up in private and agreed:

If the quality of Luo Ning's low-priced products is indeed impressive, they can purchase a large quantity of goods and then sell them to various places at a price slightly lower than the market price.

Although in this way, Cassirer Town and Surrey Town have the potential to become Chishan Town's channel dealers, they don't mind as long as they can make money.

Luo Ning saw that the two of them had such plans, and he also didn't mind this behavior.

For him, as long as he makes enough money, it is completely acceptable to give some benefits to others.

Once Philip and Thorstein get a taste of the sweetness, they will not only expand the market for him, but also actively protect his interests.

Luo Ning also saved a lot of costs in selling outside.

Win-win cooperation is also a way to make money.
