The old blacksmith seemed to understand but he was confused. In fact, after listening to Robb talking about it, he still didn't understand.

He now roughly regards carbon element as something similar to "water element", "fire element", "wind element", and "earth element". This understanding is a bit crooked, but it is barely understood.

Robb smiled and said: "I know you don't understand, but after the next key points, you will understand. Let me start with the conclusion. When the carbon element penetrates into the iron, it can make the iron hard. You already know."

The old blacksmith nodded.

Robb said: "But, have you ever thought about the ratio of carbon to iron?"

The old blacksmith shook his head.

Robb said: "I will just come to the conclusion. Iron with a lot of carbon is hard, but at the same time it becomes brittle and easy to break. Iron with a small amount of carbon is soft, not easy to break, and is conducive to distortion, but The ability to tackle tough problems is poor."

Speaking of this, the old blacksmith suddenly understood: "What you mean is to find a balance between this, as long as you find the best ratio of carbon to iron, you can make it hard and easy to be cast. But it’s not easy to break."

"Bingo!" Robb smiled: "It is fun to talk to someone who understands technology,"

The old blacksmith seemed to understand something, and exclaimed: "I understand, Her Majesty! I understand completely now."

"Really?" Robb smiled: "Then what method do you plan to use to blend the carbon element in iron?"

The old blacksmith said: "I definitely can't rub it with my hands, but I can burn iron in charcoal or coal for a long time. Anyway, if I try to find the best time for carburizing, I can mention the best quality iron. ."

Robb gave a thumbs up: "Very good plan! However, this method is still a bit stupid."

At this time, the queen couldn't help it anymore, and she said, "What else can you do?"

Robb smiled and said: "Alchemy! Treat molten iron and charcoal as two kinds of alchemy materials, and give them to the alchemists to understand and ponder to find the best match. Relatively speaking, the alchemists are looking for the two elements. The ability when combined together should be stronger than that of a blacksmith."

Miss Queen's eyes lit up, but she immediately said: "Let the noble alchemists study low-end things like iron and charcoal, I'm afraid they will not be able to accept it."

Robb grinned and showed a wicked smile: "The alchemist who can't accept this will definitely not keep up with the garbage of the times in the future. Keep it useless and kill it more cleanly."

Queen:"……"

Miss Queen was lost in thought. She found that Robb could always pull things played by the chins on the noble people, such as making iron, which used to be poor and bitter miners and blacksmiths who made soil. The stove tossed on its own, and since Robb intervened, it had become a matter of the Flame Mage.

The noble flame magician has become a worker who specializes in burning stoves. Now, in the large smelting furnace of Miss Queen, there are several fire magicians who are reluctantly in charge of temperature control, showing a very aggrieved appearance.

Now Robb actually stretched his claws to the alchemist again!

How frantic this is.

The queen couldn't help but said: "How do I feel that you are trying to turn my nobles into workers?"

Robb laughed: "I don't have one. I have been working on the liberation of labor. Whether it is ordinary people or noble labor, it must be liberated. Otherwise, I will not create that big fire box."

After hearing these words, the queen seemed to understand something, but now the queen still has enough manpower, she still can't realize the importance of saving manpower, things like fireboxes, she still feels useless.

"Well, thank you for teaching me the carburizing method." The queen calmly thanked him, and then hung up the phone, urging the old blacksmith to study steelmaking technology. At the same time, she secretly made up her mind and made gold. The warlock called a few over and asked them to study the combination of molten iron and carbon elements. Robb was right. In terms of matching elements, it is easier for a meticulous alchemist to achieve a little bit. The blacksmith's soil gameplay is unreliable.

Hang up...

The patriarch of the cats also bowed to Robb and took a large coil of steel wire to weave a net. The cats are naturally good at fishing, so they always rely on their own paws. The technique of weaving a net is very useful to him It's difficult, but fortunately, there is a technical school in Xifeng Town.

Catwoman Huahua also wanted to follow the patriarch, but Robb beckoned to her and smiled: "Huahua don't go! I'll teach you some unique tricks, which can make a lot of money."

Huahua shook his head: "I don't like money."

Robb quickly changed his words: "You can make big fish!"

Huahua jumped up: "Wow, I want I want it!"

Robb smiled and said: "Your patriarch is rich and powerful. You can use a big net to raise fish in the river, but you can't do it. You don't know anything. You are poor and have no capital. You can't raise fish if you want. So What I want to teach you is the technique of growing small fish into big fat fish."

Huahua tilted her head: "Raise small fish into big fat fish?"

Wow, my chin was covered with saliva instantly...

Robb smiled and said: "I teach you a unique fish feed formula, do you know bran?"

"You know, the skin of wheat!" Huahua said, "After the farmers harvest the wheat, the bran is useless."

In fact, it cannot be said that it is completely useless. Some townspeople who raise pigs will grind the bran into powder to feed the pigs. However, there are not many people raising pigs in Xifeng Town, and the production of bran is extremely high, so this In the end, the gadgets were discarded in large quantities and were worthless.

Robb smiled and said: "You pick up some bran that no one wants, grind it into bran powder, and then go to the soy milk maker, ask for some extra bean dregs that you don't need, stir them together, and then go. Pick up the innards of pigs, sheep, and cows that others don't want, take them back and dry them, grind them into powder, and mix them in... Finally, use the mixed garbage to feed the fish."

Huahua opened her mouth wide in surprise: "Feed this to the fish? Feed these unneeded garbage to the little fish, and they will die. The fish should eat small bugs and aquatic plants."

Robb laughed and said, "The fish that eat insects and waterweeds grow slowly, but the fish that eat the things I just said grow up fast, and they will become big fat fish in a few months."

Huahua shook her head: "Believe it or not!"

"Hey, don't believe it." Robb smiled: "Then I will raise a pond of fish by myself. You just need to come and see it every day."

Huahua smiled and said, "Can I come and eat it every day?"

"can not!"

"Then it's boring."

Robb smiled and said, "You stole the food too early. If they have not grown up, then you are at a loss. When they grow into big fat fish, I will allow you to steal it."

"Really?" Huahua was overjoyed: "Then I have to come and see it every day."
