Lord of the People: Start a monster island

Chapter 66 Weights and Measures

Jiang Heng had nothing to do today, so he just watched the iron making.

"When there is a chance to find a fire monster to help control the fire, the efficiency of iron smelting should increase a lot."

Jiang Heng said with emotion.

Murong Wen agreed: "Indeed, in this world, monsters are very powerful. With their help, everything is more convenient."

Jiang Heng didn't know much about ironmaking. He probably only knew that carbon monoxide reduced iron ore and finally produced iron.

"The quality of this carbon is very good, and the burning temperature is very high. I feel that this ironmaking should be successful."

Murong Wen observed the stove and said.

Jiang Heng also nodded, and threw a crystal nucleus to the wind-type cloud whale to make it work harder.

Immediately, the temperature of the fire in the furnace became higher.

"I'll make some molds out of soil, and the iron should be ready soon."

While talking, Murong Wen dug some rectangular molds on the ground. This method was often used by the ancients. It is simple to make, and it is easy to remove the mold after the iron cools down.

At ten o'clock at noon, red iron juice began to flow out from under the stove.

"It seems that this time the ironmaking was successful, but I don't know how the quality is."

Murong Wen took out a crystal utensil to receive the iron juice.

This utensil was also just made of mud, but it soon became a crystal utensil. It looked like a large round basin welded with a half-meter-long handle.

After the iron juice was filled, Murong Wen poured it into the mold in batches, and then waited for it to cool.

This time, about [-] catties of iron ore were added, and if there were no accidents, there would be [-] catties of iron.

When I came back from lunch, the iron had cooled down.

"A total of twenty iron ingots, each about ten catties, and about two hundred catties of iron."

Murong Wen dug out all the iron ingots, and the scales have not been made yet, so they can only rely on estimates.

Jiang Heng nodded and said: "It seems that there is nothing wrong with the method, and then it depends on the quality."

While talking, he picked up an iron ingot, and the spiritual power in his body was circulating. When he broke it hard, only a crisp sound was heard, and the iron ingot was broken into two pieces.

Iron ore is made of pig iron, which has a high carbon content and is very brittle. With Jiang Heng's current strength plus spiritual power, it can be easily broken.

Viewed from the fracture, it is off-white, with a heavy graininess, not silver-white.

"The quality of this pig iron is very poor. It seems that smelting still needs to be continued. There should be room for improvement in the method of smelting iron."

Jiang Hengdao, pig iron has high carbon content and is very brittle. We usually use wrought iron, which has low carbon content and good toughness.

There is no skill in turning pig iron into mature iron. It is to heat at high temperature to turn charcoal into carbon dioxide, thereby reducing the carbon content.

Jiang Heng remembered that this was a chemistry elective in high school.

"Indeed, the quality of these pig irons is too poor and needs to be improved."

Murong Wen also nodded.

Jiang Heng took a look, and handed the iron to Murong Wen: "Come to me when the stove is ready, and I will ask the little white snake to help you crystallize the stove."

After saying that, he turned to leave.

The weather was very hot, even in the afternoon. Jiang Heng went out to look at the charcoal kilns. There are now four here. If large-scale ironmaking is to be made in the future, more charcoal will be needed.

Ironmaking consumes a lot of charcoal.

Although a new batch of goblins were born, the manpower is still insufficient, and many people are needed for every task.

After two laps at Ziyun Whale Unicorn, Jiang Heng crossed the range of the patrol team and entered the deeper wilderness.

"Hey, you broke through!"

When he came to the place where the blood-devouring vine grew, Jiang Heng showed surprise.

It's only been two days since he threw the blood-devouring vine outside, but he didn't expect it to advance by itself. It's a four-star potential.

Sensing Jiang Heng's arrival, the Blood-devouring Vine stretched out a few vines to rub against him to express intimacy.

"I'll change the place for you. You continue to grow. You don't need to leave the monster crystal nucleus to me."

Jiang Heng touched the blood-devouring vine and said.

Then put it away and change it to another place, not only can clean up the nearby monsters, but also nourish itself.

Looking at the blood-eating vines, Jiang Heng turned around and finally returned to the pool below the waterfall to take a bath and rest.

Two days passed quickly, and the carpenter had already made the basic knives and saws, and sharpened them with a whetstone.

Then Jin Jie, an intangible cultural heritage scale maker, took them to make steelyards.

Steelyards are mainly composed of weights and beams. Weights with different counterweights can be used to produce scales of different sizes. Jiang Heng doesn't know much about this. He only knows that this is the principle of balance.

"Mr. Jin, how did you determine the weight?"

Jiang Heng asked curiously.

"Generally, the mass of a weighing mound of ten kilograms is about one catty, and it's hard for me to explain the specifics to you."

Ginger explained.

"I understand."

Jiang Heng nodded and stopped asking.

As for how to determine the weight of a catty in this different world without scales, Jiang Heng really has a way.

Because Li Wei brought a tape measure, he can get the unit of length and know the density of water. One kilogram is the weight of one cubic decimeter of water.

First use animal skin to make a water bag of one cubic decimeter as a standard, and then make a balance to determine the weight of something.

When Jiang Heng was doing this, he thought of a question, how did the first person to make the scale determine the weight of the scale.

Later he figured it out, No.1 doesn't need these things, he just needs to choose a random unit one.

How much is a catty is determined by him.

In fact, he can do the same now, but in order to be able to use the knowledge on the earth, and for the convenience of conversion, he chose the standard kilogram scale.

In two days, the first kilogram scale was born. Jiang Heng looked at the scale in his hand. The scale is [-] centimeters long, and the whole body is made of a kind of iron pear wood. Remove most of the water from it.

The maximum weight of this rod scale is only ten kilograms, but it is very standard. One cubic decimeter of water is placed on it and it weighs two kilograms.

"Great, from now on, we have scales."

Jiang Heng looked at the scale in his hand. Basic weights and measures are the starting point of a civilization. With these things, other things can have a standard of measurement.

"I live up to the entrustment of the lord."

Jin Jie cupped his hands and performed an ancient ritual. It was thanks to Jiang Heng's help that he could make a steelyard so quickly. Otherwise, it would have taken several months or even half a year to wait for the iron pear wood to dry completely.

"Haha, I will trouble you to make some fifty-kilogram scales next."

Jiang Heng smiled and said, with a standard scale, it is easier to make other scales.

"It's natural, and being a scale makes me happy."

Jin Jie said with a smile that he was very happy that the steelyard can be carried forward again. He has been making scales all his life, but with the popularity of modern electronic scales, steelyards have gradually been eliminated.

Now that he suddenly came to another world, the steelyard was once again placed with high hopes, which made him feel like a second spring, full of energy.

Returning the scale to Jin Jie, Jiang Heng was about to go home for lunch when he suddenly sensed a new breath coming from the goblin's lair.

Immediately, he rushed to the goblin tribe without stopping.

　Alas, it's late again today, the cold is too uncomfortable, and I can't wake up in the morning.
