At this time, Chen Ying was like a child, seeing a group of ants falling into a pit, and there was a pile of sand at hand, he couldn't help but have the idea of pushing the sand over to bury the ants.

This thought shocked Chen Ying's heart, he didn't know why he had such an impulse, because this was not the original plan—could it be the evil thought in my heart? But when this thought appeared, it seemed so natural.

Thousands of people were sentenced to death with the wave of his hand—what a great authority, evil as it was, but full of temptation. Chen Ying suddenly understood why Xiang Yu, Bai Qi and others would do such a big evil thing, or it was not only a military need, or it was also a psychological hidden impulse.

Fortunately for these captives, this time they were not waiting to be buried alive, and the reason why the Tang army drove them here was only because it was difficult for them to escape here.

But at this time, looking at the more than 30,000 people huddled together, Chen Ying didn't know how to choose for a while.

Bury alive?

Maybe it's really a one-and-done solution.

Zhu Hu is afraid of power and not afraid of virtue, Xue Rengui in the second year of Longshuo (662) led the Tang army and Tiele to fight in the Tianshan Mountains, Tiele sent dozens of generals to challenge, Xue Rengui responded to the battle, singled out dozens of people, fired three arrows in a row, the enemy's three generals died on horseback, the enemy army saw it, immediately chaotic, Xue Rengui commanded the army to take advantage of the situation to cover up, and then from time to time, the enemy army surrendered. Because Tiele had harassed the Tang border for decades, Xue Rengui ordered the surrendered soldiers to be buried alive on the spot to eliminate future troubles.

In the first year of Yongchun (682), Shan Yu inspected the school in Duhufu (ruling the northwest of present-day Inner Mongolia and Lingel), and the tribal official Ashde Yuanzhen defected to Ashina Gu Dulu, who claimed to be the Turkic Khan. Ashide Yuanzhen invaded Bingzhou (now Taiyuan, Shanxi) and Shan Yu to the north of the Duhufu, and invaded Yunzhou, and Xue Rengui was ordered to conquer. The Turks asked, "Who were the generals of the Tang Dynasty?" He replied, "Xue Rengui." The Turks said, "I heard that General Xue has died in exile in Xiangzhou, how can he be resurrected?" Xue Rengui took off his helmet and went to meet them, and the Turks were shocked when they took a closer look, and they all dismounted and lined up to pay respects, and gradually fled. Xue Rengui took advantage of the situation to pursue, defeated the Turkic army, killed tens of thousands of people, captured more than 20,000 people (one made 30,000), captured more than 30,000 camels, horses, cattle and sheep, and won a great victory in Yunzhou.

Pit them and make them invincible! Chen Ying thought of this, and his heart was excited. On the spot, Chen Yingzheng was about to wave his hand to give an order, when he saw a Turkic woman holding a young child in her arms, and the child was crying.

Seeing this scene, Chen Ying's heart softened again. After all, he can't become Xue Rengui, and he can't let the enemy surrender to the general!

Chen Yinglang roared: "Do you want to be a slave for the rest of your life? ”

Du Shanguo translated Chen Ying's words into Turkic. Hearing Chen Ying's question, all the prisoners of war shook their heads!

"Now this manager will show you a clear way!" Chen Ying then shouted: "There are eleven large and small coal mines near Lingzhou, you will be assigned to their respective charcoal mines, with ten households A, ten jia as forts, and ten forts as towns, all of which are divided into thirty-three towns, or digging, or transportation, how to do the work, it doesn't matter how to do the work, in order to dig the most and fastest three towns, this governor will give you amnesty, pardon the slavery status of your three towns, and give you a white place in the Tang Dynasty!" ”

Bai nationality is a kind of household registration system in the Tang Dynasty. The household registration in the Tang Dynasty was divided into nine classes, namely upper class, upper middle, upper and lower class, middle and upper class, middle and middle class, middle and lower class, lower and upper class, lower middle class, and lower class! In addition to these nine ranks, there are also white books, which are books written on white paper and used exclusively to belong to the tribes. Above the white nationality, there is the yellow nationality, which has nothing to do with the royal family, but represents a higher level of household registration. It can be regarded as a free farmer, businessman, artisan and the like in the Tang Dynasty.

It can be said that the white nationality in Datang is almost equal to the green card of the United States in later generations. The people of white nationality still enjoy the protection of the Tang Dynasty army and the constraints of the law.

The prisoners of war were suddenly boiling, and almost no one was moved. Become a citizen of Datang, even if it is only a white nationality in the process of the five-year examination, as long as it does not violate the law and discipline, pays taxes according to the regulations, and has no bad records, it cannot be converted into a yellow nationality. Live a good life.

Chen Ying continued: "If you dare to mutiny or escape, after being caught, you will be beheaded immediately!" Anyone who reports anyone who tries to escape or cause trouble will be rewarded with ten stone of food! ”

Chen Ying's setting is heaven on one side and hell on the other.

From this day on, eleven mines outside Lingzhou City began to dig coal frantically, and all the Turkic prisoners of war coincidentally worked hard, and soon, Lingzhou City completely used charcoal or dry firewood instead of coal. The coal consumed is far less fast than the coal dug out, and the more coal is piled up in Lingzhou City, it is about to be unable to put down.

Seeing that Lingzhou City was filled with thick smoke, and there was steaming everywhere. There is really no coal that can be consumed, and Yang is thinking about building all the streets and alleys in Lingzhou into fire kangs, so that people can not feel cold on the streets.

Hearing Yang Ze's crazy idea, Chen Ying hurriedly stopped.

Maybe Yang Ze really dared to do this.

Chen Yingdao: "No matter how much coal you have, you can't waste it so much, this is what the general manager has consulted the Lingzhou County Chronicles and found that Lingzhou is rich in iron, and the Turkic prisoners of war will be divided into a part to mine iron ore, so that the excess coal can be used to make iron!" ”

"How can coal make iron?" Although Yang Ze was not good at steelmaking, he also knew that charcoal must be used for ironmaking, and it was good willow charcoal. This is the most basic common sense.

In fact, this common sense in antiquity is wrong. Chen Ying is also a highly educated person in later generations, and he certainly understands that because coal contains more harmful components, it will affect the quality of steel when it is used to make steel. In later generations, whether it was steel or iron, in fact, it was not direct coal, but coke. Coke, on the other hand, is relatively pure and suitable for steelmaking and ironmaking.

The construction of blast furnaces is not complicated, the "Great Leap Forward" at the end of the 50s called on the people of the whole country to make steel, and even some primary school students, villagers in the production team, and salesmen in non-staple food stores formed iron-making teams to build blast furnaces to make steel and iron. The technical level of those blast furnaces is theoretically capable of making iron, but the technology is not mastered, so most of them are not finished.

Chen Ying found Lin Chuanfu and explained the blast furnace in his memory to Lin Chuanfu.

As a professional, Lin Chuanfu quickly came up with the technical problems that would be encountered in this blast furnace, refractory bricks and bellows.

Refractory bricks are refractory materials made from refractory clay or other refractory raw materials. Pale yellow or brownish. It is mainly used in masonry smelting furnace and can withstand high temperature of 1,580°C to 1,770°C. Also called fire bricks. For example, refractory clay bricks, high-alumina bricks, silica bricks, magnesia bricks, etc.

Although Chen Ying knew about high-alumina bricks, silica bricks and even magnesia bricks, all he knew was a name, and he had never even seen any style. What's more, in this era, the chemical elements are still blank, and it is really not an easy problem to find these materials.

Chen Ying was not intimidated by the difficulties, he asked the troops to teach Wei Wenzhong, Gao Yunquan and He Yuejing to be responsible for training, and he took Lin Chuanfu and a group of craftsmen to conduct experiments.

That's right, Chen Ying has adopted a very stupid method, which is to use clay of different materials and conduct repeated experiments. Just when Chen Ying was preparing for a large-scale steelmaking in Lingzhou, the battle report of Chen Ying in Lingzhou also reached Chang'an.

Chen Ying didn't know that he was an otherworldly butterfly, which set off a political storm for Chang'an.
