Three Kingdoms: Opening War Strategy System

Forge Yard.

"Your Highness."

The official in charge of the Forging Institute greeted him from a distance and said with a respectful salute.

"No need to be polite."

Liu Chen waved his hand and handed over the formulas of "water wheel" and "nitrogen, phosphorus and potassium fertilizer" to the responsible official.

"The water wheel can save manpower and run automatically by the water power. Nitrogen, phosphorus and potassium fertilizers can speed up grain growth and increase yields..."

Listening to Liu Chen's narration, the official in charge of the Forging Institute said with a look of surprise:

"This thing must increase the yield of farmland and reduce manpower and material resources, His Highness is really a wizard!"

"In case I didn't invent it, you would have been on the horse's leg." Liu Chen scolded with a smile.

"How is it possible!"

The official of the Forging Academy said with a shocked expression: "Apart from a wizard like His Highness, how can anyone in this world make such an ingenious invention!" "

Liu Chen's expression was calm, but he was a little slander in his heart.

No wonder there have always been people who want to climb up throughout the ages, and this kind of words and deeds of listening to subordinates pat horses is indeed very fulfilling!

"Okay, get down to business."

Liu Chen also took out the "cement" and "red brick" formulas.

This is related to the future house reconstruction and road construction in Changshan, but it must not be sloppy.

"This is a cement and red brick formula, the forging institute immediately studied and manufactured, if you don't understand something, you can come and ask King Ben."

Liu Chen handed over the formula to the official in charge of the Forging Institute, who had followed Chang Shan since his father, was faithful and absolutely sincere.

Of course.

The Forging Institute has too many secrets from Changshan, and it is also guarded by elite soldiers, and every official has surveillance.

This is not that Liu Chen is not worried about them, but that the heart of defense is indispensable. Even if he relaxed, the soldiers and advisers under him did not dare to rest assured.

After the official in charge of the forging institute took it, he raised his eyes and swept it up, looking at the formula material on it, but he was shocked!

Having dealt with these for many years, he quickly saw that these formulas were unusual.

"Your Highness, your subordinates immediately began to prepare."

Liu Chen and Frustrated did not leave, but followed the responsible official inside to observe.

The refining of cement and red bricks is carried out in the furnace, and there is naturally no shortage of kilns in the forging yard.

Liu Chen observed that the coal excavated from the coal mine had been used as fuel in the forging yard.

Coal is hotter than charcoal.

Looking at the kiln, Liu Chen suddenly thought of "glass", if he had time, he could start producing glass.

In fact, glass has been around for a long time in ancient times.

However, ancient glass is simply "low-temperature lead barium glass", which can also be called "glass".

The glass is colorful and crystalline, but it is brittle and brittle, not resistant to high temperature, and not suitable for the shortcomings of sudden cold and heat, and is not suitable for becoming a living vessel.

The "glass" mentioned by Liu Chen is "soda-lime glass", which is strong and durable, and does not explode when heated.

Not only can it be used as eating utensils, door and window lighting, glass mirrors, glass greenhouses, but also telescopes, myopia glasses, and reading glasses.

It can be described as very useful.

......

When Liu Chen wandered outside the world and reverie about glass, the officials in charge of the forging institute on the side persuaded Liu Chen to leave one after another.

After all, the high temperature here is sultry, which is really not suitable for Liu Chen to come condescendingly.

But Liu Chen didn't care, the appearance of cement and red bricks, but there were earth-shaking changes to the construction.

Red bricks are quickly refined, after all, only clay needs to be made of adobe, and briquettes and bricks are fired in the kiln, which is roughly the same as the firing of green bricks.

However, green bricks need to add water during the firing process, and red bricks do not need to add water.

After the red brick is successfully fired, it will be tested in the surprise of everyone.

Finally, it was found that red bricks were not as strong as green bricks whether they were strong, alkali resistant, and durable.

However, the firing process, energy consumption, output, cost, etc. of red bricks are far lower than those of green bricks.

It can be said that the production is simple, efficient, and can be applied more extensively.

"Although red bricks are not as good as green bricks, if there is cement to match, they are perfect."

Frustrated, he commented in surprise: "At that time, the cost of housing construction will be greatly reduced. "

Liu Chen's head is now waiting for cement to be produced.

However, for cement refining, it has been difficult to succeed, either the strength is not enough, or the quality is not up to standard.

People pondered and could not find a solution.

At this time, Liu Chen suddenly saw the blower and understood the problem.

Whether it is fired cement or red bricks, extremely high furnace temperatures are required, but without the support of the industrial system, the temperature can only be raised by oxygen combustion and fuel.

Change charcoal to coal to raise the temperature of the kiln. But this is not enough, you also need to improve oxygen to fuel combustion, that is, to blow air into the stove.

The current blower uses an airbag to blow air, and the efficiency and wind speed are obviously not good.

"Bring pen and paper."

Liu Chen waved his big hand, and soon someone took the paper and pen, and he described the bellows structure in his mind.

Liu Chen still remembered a lot of things in his mind, these were miscellaneous books he had read in his previous life, perhaps because of the passage, his memory had been improved.

The bellows did not appear until the Ming Dynasty, and after Liu Chen's drawing, everyone gradually saw this thing in the afterlife, and then their faces were a little shocked!

"Okay, let's start manufacturing now."

Most of the items needed for the bellows are mostly wood, and after a small half-hour of transformation, the first wooden bellows finally appeared.

After the official pushed and pulled, the wind blew into the kiln, instantly causing the temperature to skyrocket again.

"The temperature has risen!"

"Your Highness is really a god man! This bellows is also good for our iron smelting! "

"Wonderful!"

Everyone was instantly a little surprised, and the increase in temperature meant that Liu Chen's bellows was indeed useful.

And under the push and pull, it is more labor-saving than the air bag blow.

"Keep firing cement." Liu Chen said with a smile.

After Liu Chen's transformation, the addition of the wooden bellows made the temperature of the kiln rise again, and the cement was quickly fired.

After a series of processes, looking at the cement in the later life, Liu Chen was not dirty, reached out and grabbed a handful, and his heart was a little excited.

After testing, the combination of cement and red bricks is indeed seamless and perfect, whether it is strength, strength, bonding speed, etc., it is very good!

"In the future, brick houses will be built with cement and red bricks. I will hand over to you the architectural drawings of the plan and the drawings of the torch heating. Liu Chen said.

Next, not only to build a new house, but also to transform the heating project of the house, the torch will undoubtedly come in handy.

At that time, there will be no cold winter in Changshan!

"Yes! Lord! "

Frustrated and others said yes.

Liu Chen

continued

"The firing of cement and red bricks should be increased.

"I am also going to build roads with cement to connect Changshan counties, and when the time comes, the march, trade, grain transportation and other issues can be greatly improved."

"Yes! Your Highness! "

The officials in charge of the Forge Academy, as well as the surrounding officials, said yes.

After a series of instructions were given, Liu Chen did not stay any longer and left the forging courtyard with frustration.

As soon as the group walked out of the door, Tian Feng and Guo Jia hurriedly arrived.
