Three Kingdoms: Starting War Strategy System

Forging yard

"Your Highness."

The official in charge of the forging institute came out from a distance and saluted respectfully.

"No need to be polite. Liu

Chen waved his hand and turned the"waterwheel""、"The formula of"nitrogen, phosphorus and potassium fertilizer" was handed over to the responsible official

"Waterwheels can save manpower and run automatically by 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 surprised look on his face:

"This thing will definitely increase the yield of farmland and reduce manpower and material resources. Your Highness is truly a genius!"

"In case I didn't invent it, your flattery has hit the horse's leg. Liu Chen scolded with a smile.

"How can it be! The official of the Forging Institute said with a shocked look on his face

:"Apart from wizards like His Highness, how can anyone in this world make such an ingenious invention?""

Liu Chen looked calm, but there was some slander in his heart.

No wonder there are always people who want to climb up through the ages. Listening to the flattering words and deeds of subordinates is indeed very fulfilling!

"Okay, let’s 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, so we must not be careless.

"This is a recipe of cement and red bricks. The Forging Institute will immediately research and produce it. If you don’t understand anything, you can come and ask me."

Liu Chen handed the formula to the official in charge of the Forging Institute. This person has followed Chang Shan since his father, and he has been loyal to his duties and is absolutely sincere.

Of course.

The Forging Institute has too many secrets from Chang Shan and is also guarded by elite soldiers. Every official has There is surveillance.

It's not that Liu Chen doesn't trust them, but that he must be on guard against others. Even if he relaxes, the soldiers and counselors under his command won't dare to rest assured. After the official in charge of the forging institute took it, he glanced up and saw Looking at the formula materials above, he was shocked!

Having been dealing with these for many years, he quickly saw how unusual these formulas were.

"Your Highness, my subordinates immediately started preparations."

Liu Chen and Jushu did not leave, but followed the official in charge to observe.

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

Liu Chen discovered after a brief observation , the coal excavated from the coal mine has been used as fuel in the forging yard.

Compared with charcoal, coal has a higher temperature.

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

In fact, glass existed very early in ancient times.

However, ancient glass was just a simple"low-temperature lead-barium glass", which can also be called"glazed glass".

Glazed glass is colorful and crystal-clear, but it is brittle and not durable. The shortcomings of high temperature and inability to adapt to sudden cooling and heating make it unsuitable for use as living utensils. The

"glass" Liu Chen refers to is"soda-lime glass", which is strong and durable and will not explode when exposed to heat. It can not only be used as eating utensils, doors and windows Lighting, glass mirrors, glass greenhouses, and can also make telescopes, myopia glasses and reading glasses.

It can be said to have a wide range of uses

……

When Liu Chen was wandering around and dreaming about glass, the official in charge of the forging institute on the side repeatedly persuaded Liu Chen to leave.

After all, it's hot and muggy here, and it's really not suitable for Liu Chen to deign to come here.

But Liu Chen didn't care at all. The appearance of cement and red bricks brought about earth-shaking changes to construction.

The red bricks were refined very quickly. After all, they only needed to use clay to make adobe. The briquettes and bricks were added to the kiln for firing, which was roughly the same as the firing of green bricks.

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

After the red bricks were successfully fired, they were tested amidst everyone's surprise.

Finally, I found that red bricks are not as strong as green bricks in terms of strength, alkali resistance, and durability.

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 it is simple to produce, highly efficient, and can be applied more widely.

"Although red bricks are not as good as blue bricks, if they are matched with cement, they will be perfect.

Jushou commented in surprise:"The cost and efficiency of house construction will be greatly reduced by then.""

Liu Chen nodded, and now he is waiting for the cement to be produced. However, the refining of cement has been difficult to succeed. Either the strength is not enough, or the quality is not up to standard.

Everyone thought hard and couldn't find a solution.

At this time, Liu Chen suddenly saw When I went to the blower, I understood the problem.

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

Replace charcoal with coal , to increase the temperature of the kiln. But this is not enough. It is also necessary to increase oxygen to support combustion, which is to blow air into the furnace.

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

"Get a pen and paper."

Liu Chen waved his hand, and someone quickly brought a pen and paper over, 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, maybe because Because of the time travel, the memory has been improved.

The bellows did not appear until the Ming Dynasty. After Liu Chen's drawings, everyone gradually saw this thing from later generations, and then their faces were a little surprised!

"Okay, let’s start making it immediately."

Most of the items needed for the bellows are made of wood. After half an hour of modification, the first wooden bellows finally appeared. After the clerk pushed and pulled it, strong winds blew into the kiln, instantly causing the temperature to skyrocket again.

"The temperature has increased!"

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

"How wonderful!"

Everyone was a little surprised for a moment. The increase in temperature means that Liu Chen's bellows is really useful.

And when pushed and pulled, it is more labor-saving than air bag blowing.

"Continue firing the cement."Liu Chen nodded and smiled.

The drum was as powerful as a tiger. After Liu Chen's modification and the addition of the wooden bellows, the temperature of the kiln increased again, and the cement was quickly fired. After a series of processes, looking at the cement of later generations , Liu Chen didn't mind it being dirty, so he stretched out his hand to grab a handful, feeling a little excited.

After testing, the combination of cement and red bricks was indeed seamless and perfect, no matter in terms of strength, strength, bonding speed, etc., it was very excellent!

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

Next, not only do we need to build new houses, we also need to renovate the heating projects of the houses. The fire kang will undoubtedly come in handy.

By then, Changshan will no longer have cold winters!

"yes! Lord!"

Jushou and others raised their hands and agreed.

Liu Chen nodded and continued:

"The amount of cement and red bricks needs to be increased when firing.

"I am also planning to build roads with cement to connect the counties in Changshan. By then, issues such as marching, trade, food transportation, etc. will be greatly improved."

"yes! Your Highness!"

The official in charge of the forging institute and the surrounding officials agreed.

After a series of instructions were issued, Liu Chen did not stay any longer and left the forging institute with Jushu.

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