Eight Thousand Iron Buddha at the Start, Please Make Concessions to the First Emperor!

Chapter 277 Unlock a new technology tree, epoch making steel!

At the entrance of the passage is something similar to a stove. There is a wood entrance on the front of the stove, and an opening on the side to dissipate the smoke. There is also an iron vessel on the top of the stove, which is connected to the side passage, and the interface is closed by trihexite. place.

There is also an opening above the entire vessel and the three-height clay, where the water is added, and it will be closed with a lid after the addition is complete.

As for the other side of the passage, it extended into the bedroom, and then Zhao Tuo asked someone to bring some old clothes and sealed up the ventilated places, leaving only the opening of the gate.

"You go to the stove over there to burn water, remember to put more wood.

A group of eunuchs nodded immediately upon hearing this.

The stoves in Xianyang Palace generally use pine charcoal, that is, charcoal cooled after burning pine wood. This charcoal can be easily ignited without smoke, which is really good.

However, Zhao Tuo wanted a fire, so he asked people to take raw pine wood.

Soon, the fire in the stove outside started to burn, and the smoke was dissipated along the small opening 19, and a large amount of heat was transferred to the utensils above.

Soon the water in the vessel began to boil, and the water vapor began to evaporate, but because it was sealed everywhere, the water vapor could only start to move along the passage, and finally came to the inside of the bedroom.

The cotton cloth at the entrance of the passage hindered the continued progress of the water vapor, so that they re-turned into water and fell into the container below. As for the heat, it was released into the air inside the bedroom.

After a while, the entire bedroom was warmed up.

Zhao Tuo felt the temperature rise in the room and sat down again.

With the double protection of the stove and heating, Zhao Tuo's hands are finally not cold.

The eunuch felt the change of heat and cold in the room, and couldn't help but be greatly surprised, and looked at Zhao Tuo's eyes full of admiration.

Zhao Tuo did not expect that this method would spread in the palace so quickly.

Many concubines and ministers followed suit, and everyone was talking about it for a while. Even above the court, the ministers were asking whether the other party had installed heaters.

What is even more surprising is that this method was soon spread in Xianyang City, and everyone got such a heater at home.

For a while, the price of wood has risen a little, and the people who sell wood and charcoal in the mountains are all smiles.

I am even more grateful to His Majesty the Emperor of Daqin. We must know that in the previous winter, although they could sell some, most of them were charcoal.

Pine is a kind of log, but very few people will buy it, and charcoal is often not enough to burn a single tree, and many of them are turned into ashes.

"I don't like going out now.

"It's freezing and snowing outside, but it's still comfortable at home, with heating, and you don't have to worry about shivering from the cold. 59

"On the charcoal alone, half of it is warmed, and the other side is cold, but the heating is comfortable."

In the Xianyang Palace, Zhao Tuo just finished his morning court.

After returning to the dormitory, Zhao Tuo sat down directly, and he had not had time to use the large amount of fame he had gained some time ago.

Just when I was free today, Zhao Tuo directly opened the system interface.

Then directly used to get a lot of prestige soon, and began to unlock an item below the system.

As a lot of prestige wanes, the system begins to emerge with words.

"Unlock the steel forging process..."

Looking at the text that appeared, Zhao Tuo couldn't help being surprised, it was actually steel!

Zhao Tuo originally thought that Steel needed more prestige to appear, but he didn't expect it to be unlocked directly after defeating the Peacock Dynasty this time.

You must know that what Daqin lacks in the army today is not people, but weapons.

And there are many other uses of steel, such as iron armored ships, steel chariots, and even farm tools used by farmers. Once replaced with steel, it can completely show its strength.

This is an important invention that can truly divide an era.

The civilization capable of smelting steel is simply crushing the bronze civilization in all aspects.

Although today's Daqin also has iron tools, they are all pig iron.

The main difference between iron quality is the carbon content. Iron with carbon content higher than 2% is called 927 pig iron. Although pig iron has surpassed bronze, its own carbon content makes pig iron destined to be easily broken and rusted. , it needs to be rebuilt afterwards.

In the previous battlefield, the soldiers of Da Qin brought back a lot of these broken iron tools.

Iron with a carbon content lower than 0.05% is also called wrought iron. Although wrought iron is no longer easy to break, the hardness of wrought iron is very low due to the low carbon content, and even It also bends when fighting.

And between the two is steel, a material that is hard and not easy to break and rust. If you can control the uniform distribution of carbon in the steel and the removal of magazines, you can even cut iron like mud. .

Once this kind of steel is produced, Daqin's military, navigation and even agriculture will be able to directly enter a new stage.

But the forging of steel is not a simple thing, and the first thing is iron ore.

The stock of iron ore directly determines the future of Daqin.
