Secretly summoning the furnace of life and death, Si Yuan took out five spell-shaped intentions, which were formation diagrams that had been randomly and accidentally smelted over the years.
This time, he threw it to the black widow and gave the order.
"You should take these things first and start to comprehend them yourself."
"If you don't understand something, you can ask me for advice."
"During this period, you will live in the side courtyard of the house. If you need food, water, etc., a servant will bring it to you every day."
When the Black Widow heard Wei Anhou's order, she immediately lowered her head.
Respond respectfully.
"I will obey the orders of the Lord of the Palace!"
Wait until she heard the sound of footsteps and raised her head again.
She saw that Wei Anhou Siyuan had already gone away alone, leaving only an identity token and five arrays, spells, and intentions in her place.
…
…
Return to your private study room.
Si Yuan sat at the front seat, unfolded a piece of white paper, and motioned with his eyes to the maid to come over and study the ink.
At the same time, he carefully recalled in his mind the easiest to popularize, the lowest cost, and the most effective means of preventing coldness.
Soon.
Si Yuan thought of a suitable target.
“In this era, the basic methods of keeping out the cold are floor kangs.”
"Although the prototype of the fire kang exists, and perhaps the finished product has appeared in other cold places, at least in Wei, I have never seen it."
"Then choose fire pits and fire walls to popularize them on a large scale."
"Preparing for the next super cold winter disaster."
Think quietly for a moment.
Si Yuan picked up the brush, dipped it in ink, and began to draw on the white paper on the desk.
He first drew two houses, one large and one small.
The larger houses are marked as bedrooms, and the smaller and connected houses are marked as woodsheds.
The wall structure is not a common single-sided wall.
It is a double-sided wall with a hollow structure.
The outer wall is extremely thick and has good heat insulation effect, while the inner wall is thin and has good heat dissipation effect.
And inside the dormitory, a fire bed is simply outlined in two or three strokes.
More than a dozen thin lines are mixed in, indicating that they are barriers to the fire channel, used to transfer the heat and smoke brought by combustion.
Si Yuan did not follow the conventional method and leave the fire opening directly inside the dormitory.
Instead, it is imported into the small woodshed connected to it.
And it is connected to the hollow area of the fire wall near the burning port of the fire kang, so that the inside of the fire kang and the inside of the fire wall become a whole.
In this way, there will be no smell of burning smoke inside the dormitory.
Always keep the air fresh and warm.
More importantly, there is no need to worry about harmful and toxic gas residues produced during combustion.
And it only needs to be ignited and burned in a burning port, and the heat generated will naturally circulate in the fire kang and fire wall.
Finally it is discharged to the outside through the chimney of the fire pit.
"Just draw a rough outline and leave the remaining changes and adjustments to the appropriate details to the craftsmen in the mansion."
"After the drawings are completed, a batch of fire pits and fire walls will also be built inside the mansion."
Si Yuan put down the brush in his hand, picked up the crude drawings he drew and looked at them.
Gu Mou
Although it is a simple drawing and extremely crude, some relevant key points are all marked, and there are not many omissions.
"The maids, slaves, dancers, singers, chefs, guards, concubines, etc. in the house."
"There are also a number of sons and daughters who will be born in a few months."
"Many of them have very limited physical strength. If they are left alone, they may not be able to withstand the super cold winter disaster that will follow and will freeze to death."
How to choose the appropriate burning material, Si Yuan thought carefully and quickly made a decision in his mind.
The first priority is cost-effectiveness.
The price of incendiary materials should not be too expensive, otherwise ordinary people will not be able to afford them.
Otherwise, everything is in vain.
Secondly, there is the impact of burning materials on the environment. He does not want the place where he lives to be filled with smoke and dust pollution.
Make it uncomfortable for yourself to breathe.
As for the third point, it is the difficulty of mining and manufacturing combustible materials. It needs to be simple enough. Too many manpower and material resources cannot be invested in this aspect.
The fourth point is that the burning material must have a sufficiently high combustion heat release.
"Something similar to briquettes is a good universal burning material in winter."
"Mix wood or leaves, weed debris, soil, water, and coal powder in a certain proportion, and then press it."
"Then it is left to dry naturally to evaporate the remaining moisture inside."
Si Yuan picked up the brush and wrote down relevant things on another piece of white paper.
Coal contains high amounts of heat released when burned, and the fiefdom he chose actually contains a huge amount of underground coal resources.
In addition, there are other untapped precious mineral resources.
This is a real treasure trove waiting to be developed.
The mixing of soil and water further reduces the cost.
Wood, blade debris, etc. make the ignition process not so difficult, and also increase the durability of combustion and improve resource utilization.
"At that time, the production and sales will be handled jointly by the Furniture Hall and the Juquan Hall."
"The sales price does not need to be set too high."
"We must make it affordable for the vast majority of civilians and ordinary people. We can not only take advantage of the opportunity to earn a lot of wealth again, but also protect the people in the fiefdom from the next super cold winter disaster."
When Si Yuan picked up his pen to write, his pen moved like a dragon or a snake.
He wrote hundreds of words of the general outline of the plan in a eloquent way.
After finishing it, he put down the brush in his hand, rolled up the two pieces of white paper, and handed them to the beautiful maid who was a loyal soldier standing by his side.
And gave instructions aloud.
"The design drawings will be handed over to the Furniture Hall, and the internal craftsmen will start optimizing and constructing them. A group of relevant apprentices will also be trained, the number of which should not be less than 10,000."
"As for the other one, give it to Juquan Palace and let them estimate and set the price."
The maid beside her stretched out her white hands, lowered her head and respectfully took the two pieces of white paper.
Then he bowed to his master, Marquis Wei An, and excused himself.
"Although the coal resources within my fiefdom are huge, they are nothing compared to the entire Wei State."
Si Yuan thought quietly and carefully recalled the relevant memories of his past life.
At the same time, compare the territorial map of Wei State in this life.
"In the entire Central Plains, about 70% of the coal resources are located throughout Wei State, and most of them are open-pit coal mines."
"Following closely behind, Zhao State in the north ranks second in terms of reserves."
"The State of Yan ranks third."
At this time, the melting of iron and steelmaking all used coal as the combustion material to provide higher temperatures.
Although Wei's steel-making technology is not as good as that of neighboring Korea, it is not bad. It's just that a lot of it is used to forge exclusive equipment for Wei soldiers.
