Siheyuan: I decide the fate of the world with my medical skills

"Your Majesty also pointed out a countermeasure, which is to add loess and water when burning coal, and then use hollowed-out bamboo sticks to expel most of the harmful gases to the outside."

Blocking Fusu, he listened to Zhang Han's generous smile, he just shook his head and smiled bitterly - to people of that era, it was difficult for them to understand information such as incomplete combustion, the production of carbon dioxide, or the sulfur content in coal.

The original planned users included warriors on the expedition against the Qiang people, as well as criminal laborers who were setting up Linqiang County on the Qinghai coast to manage the Longxi Army and perform labor to repair the Great Wall.

A wood block stove with briquettes provides a constant supply of hot water and helps keep out the chill of the cold.

What about the highly toxic substances that may be produced by incomplete combustion?

Please laugh, their temporary residence is not a tightly sealed building, some tiny gases will also spread out!

More importantly, Daqin was in a relatively warm season, and until the early Western Han Dynasty, the Guanzhong Basin was still suitable for growing southern fruits.

And according to reports, a white rhino was spotted on the grasslands of Shangjun.

So, taking advantage of this favorable climate, Fusu hoped that the Qin Dynasty could gain as much benefit as possible from the territory of this earth. Even if the future successor was not satisfactory, the ancestral foundation could be guaranteed to continue for a few more years...until five hundred years later, there would be a monarch who would revive the country.

Standing at this critical juncture, with Jincheng County as the core, we will continue to compress the spatial resources of the Qiang people and the Northern Xiongnu. Under strong pressure to the west, we will try to persuade their tribes to move inland as a whole, so as to control the Hexi Corridor region in a bloodless war.

What followed was the opportunity to open up a new Silk Road, attempting to make the "Banliang", a copper coin commonly used by all countries, the core currency unit of the entire channel network, and establish the Qin "Banliang" system. By drawing wealth from Central Asian countries and the eastern Mediterranean, the proceeds would be used to ease domestic burdens, so as to avoid repeating the mistakes of "the old Qin Dynasty welcomed Pei Gong"!

In order to allow Li Xin to gain a decisive advantage, Fusu also prepared a generous secret gift for the Shouling Qiang tribe.

Fusu looked at Feng Quji and others who had already had some basic understanding of the structure of honeycomb coal, and then gave instructions to Sima Chang, guiding them to another place where the sound of horses neighing could be heard continuously.

Meng Tian frowned as he watched a dark brown warhorse being pulled into a strangely shaped iron cage and then tied tightly with several ropes.

"Your Majesty, what does this mean?" He asked this question in confusion.

Fusu smiled and responded, "This is something new for horses - horseshoes. I designed this cage especially for this situation. There are ropes on the top to ensure that the horse does not move around, and chains are installed under the cage to prevent the horse from kicking from behind."

Meng Tian walked closer and took a closer look. It was indeed as Fusu said. The design of the cage and rope only restricted the movement and possible impact of the warhorse, and would not cause any harm to the warhorse.

After Meng Tian finished reading and confirming all of this, Fusu nodded slightly to Li Cheng who was standing nearby. Li Cheng immediately understood what he meant, so he ran into the stable and pulled out a strong and tall horse that was more than 1.4 meters tall.

He then ordered two soldiers to equip the horses with vests, and with the help of several people, he put on the new heavy equipment.

Not long after, the heavy armor that Fusu remembered - or the so-called heavy cavalry suit, appeared in front of Meng Tian and others.

Li Cheng was wearing a set of heavy armor that combined the features of plate armor and zip-lock armor. Except for the armor that completely surrounded his head and had two ventilation holes on it, almost all parts of his body that were vulnerable to injury were completely protected.

The horse armor that the warhorse is equipped with is also fully covered, including a horse head cover, a neck ring, armor, a torso cover, a back reinforcement, etc.

This..." Meng Tian, ​​Qiang Wei and others couldn't help but move closer. They stretched out their hands to touch the armor on Li Cheng's body, but their hands finally stopped in mid-air.

The eye contact between them revealed that they were about to take off the bride's red veil!

But in Li Cheng's eyes, he was completely unaware that there were many men around him who were obsessed with the armor on him.

He tried to move his hands, which were covered with heavy metal gloves. Although he could not use a bow and arrow, he had no problem holding a spear or sword.

Next, he moved his neck again, and through the gap in the armor he saw Qiang Wei, who looked hurried due to his rapid breathing.

"Tai, Taiwei, what are you doing?"

Qiang Wei answered simply and decisively: "Take it off!"

Meng Tian simply said: "Take it off!"

Wei Liao was relatively more restrained. There was also a gleam in his eyes as he admired the beauty of Li Cheng's armor, but he still stepped forward and asked Fusu:

"Your Majesty, would you like to know how many cavalry like this we will have when we go out tomorrow?"

"Prepare at least 500 fully armed cavalrymen." Fusu stretched out his hands and gestured, indicating the number he had in mind.

Wei Liao nodded, but then shook his head: These 500 fully armed cavalrymen alone are enough to effectively prepare for the threat from the Xianling tribe; but to deal with the Xiongnu people that we may encounter, it is still far from enough!

Fusu said: "Respected old Prime Minister, the factor that hinders the development of heavy cavalry is not the weapons, horses or knights themselves, but the key is those superior horses!"

Wei Liao frowned and asked in confusion: "Your Majesty, what do you mean by this?"

Fusu recalculated the numbers in his mind. "For example, Li Cheng weighs about 280 pounds, and the combined weight of his weapons and armor is 100 pounds. The horse armor used by the heavy knight adds another 40 pounds of weight, plus other loads, which makes the horse's load-bearing burden exceed 400 pounds."

“In fact, the load-bearing capacity of a horse should be controlled at about one-third of its own weight, and preferably no more than one-quarter!”

"This means that a horse used by a heavily armored knight to ride on would have to weigh at least 1200 pounds."

"Among thousands of high-quality war horses, I have only found more than 400 that meet this standard, less than 500. We need to further screen in the Longxi army to meet the demand."

Wei Liao sighed helplessly and remained silent. He knew that the current Qin horses were no taller than 6 feet at the shoulder and weighed about 500 to 550 pounds.

Seeing Wei Liao's sad face, Fusu also sighed softly.

“Heaven has its way. It cuts away the excess and makes up for the deficiency.”

The gods of nature endowed the Chinese nation with vast plains and farmlands, and also bestowed certain blessings on other ethnic groups.

Take horses for example. Central Asia and the Near East have excellent horses, such as the Uzbek and Turkoman horses. The Bactrian is an outstanding representative from,

Compared with them, the horses of Hequ (Hejian) in the Tang Dynasty are only one level lower. However, the horses of the Hulu people are worthless in terms of value judgment.

Fusu was most interested in Bactrian horses, as he recalled in his mind that many famous horses in history actually originated from these fine breeds.

For Fusu, the problem of improving horse breeds would not be a problem once the Silk Road was opened.

Since it was Dayuan that didn't let the purebred horses out of the country? Huh? Could it be that Qin's sword had no profit to cut?

On the other hand, after Meng Ying's armor was ruthlessly taken off by Qiang Yan and Meng Tian, ​​he was left with only a white underwear tightly wrapped around him. He curled up in the corner, trembling constantly.

Originally, he should have been ahead of everyone else, both in armor and halberd... but now his face was full of regret for his unfilial behavior, and his face was filled with remorse.

When Fusu saw Meng Tian rolling up his sleeves and snatching the ring-handled sword from his son's hand, he couldn't help but smile bitterly when he thought of the bronze sword they had built together to replace the current equipment in the future.

China was a copper-poor country, and recycled bronze swords were melted down and recast into Qin Banliang coins, helping to alleviate the shortage of coins in circulation on the market.

To be honest, if it was for the sake of the image of the imperial capital, Fusu even had the idea of ​​melting the twelve pure gold statues outside the Xianyang Palace into gold and silver for use!

When the currency reserves are sufficient, the Qin Banliang monetary system can be promoted on a large scale in the country.

On the other side, after the emotional climax of the two long-time lovers, they returned the heavy armor and the round-headed sword to Meng Ying, straightened their clothes, and returned to the court again.

Seeing this, Fusu prepared to take them to see a new product in the industrial zone, namely cement - or more accurately, a simplified version of slag-mixed soil cement.

The specific process is: first, the lime (calcium carbonate) as the main ingredient is calcined at high temperature to decompose into quicklime, which is then ground. Then, gypsum and soil are mixed, stirred and further crushed, and calcined at high temperature again. Next, the clinker is taken out and mixed with iron ore waste, and ground again to form powder. At this point, slag cement is produced.

Compared with the various types of cement produced industrially in the future, their technology still has huge differences - both in manufacturing technology and actual performance.

As for the strength of the finished product, it is probably difficult to compare with the solid material formed by the construction method used by Helian Bobo.

But the key now is - after solving the problem of whether or not, in order to allow traces of Qin culture to appear in barbaric areas such as the Western Regions and the South China Sea - it is necessary to first build indestructible urban facilities and defensive fortifications in this area.

If the city was built by recruiting many forced laborers to manually fill the earth mounds, Emperor Gaozu of Han might have sent troops to Xianyang to seize Empress Lü by the time the city was completed...

Taking this into consideration, they mixed cement and bricks to build several small defensive fortresses in the expansion area in advance. When the time was right, they built walls to surround it. By expanding the points, they promoted the development of the surrounding areas and gradually consolidated the local status and control range.

Just as the Zhou emperor implemented it in the beginning to the fiefdoms of princes.

As Fusu's thoughts jumped, they stopped and walked to a kiln where a blazing fire was burning. They saw a group of prisoners wearing thick linen veils on their faces, looking around at the soldiers who surrounded them with fear and panic.
