The establishment of the Tang Dynasty was usually based on the three levels of "Dao", "Prefecture" and "County", which can be compared with the provinces, prefectures and counties of later generations. At the military level, they are collectively referred to as governors, and the governors are equivalent to the governors of later generations, and the prefectures and counties under their jurisdiction are different, especially the governors of the annexed states (later changed to the governors) have jurisdiction over the military of the twenty-four states around the annexed states.

Chen Ying was in charge of Lingzhou in the year of the weak crown, and he was also in charge of the military of the six states. In fact, this is a big pit, the Tang Dynasty refers to Fengzhou, not Fujian Fengzhou (Jin'an County) but refers to the Eastern Wei Dynasty placed in the South Hengzhou (Inner Mongolia Wengniute Banner Wudan Town), later changed to Fengzhou, but since the end of the Sui Dynasty was annexed by the Turks, until the fourth year of Zhenguan Li Jing night attack on Yinshan, Fengzhou was re-included in the Tang Dynasty territory.

Now Fengzhou has jurisdiction over Jiuyuan and Yongfeng counties. Shengzhou has jurisdiction over Hebin and Yulin counties. Xiazhou Lingshuofang, Dejing, Ningshuo three counties, (all in the border of today's Jing), Yinzhou Lingzhen Township, Kaiguang, Rulin three counties, Suizhou although the jurisdiction of eleven counties, Huazhou jurisdiction of seven counties, and then the egg, at this time is still the territory of Liang Shidu.

Looking at the land nominally assigned to Chen Ying's seven prefectures (including) a total of thirty-four counties, however, in fact, the only ones that can be commanded by Chen Ying are the five counties of Lingzhou (Huaiyuan is still in the hands of the Turks), and the others are either in the hands of the Turks or in the hands of Liang Shidu, in fact, Chen Ying only got an empty name.

Hearing that Li Yuan was righteous and awe-inspiring, he wanted to reward Chen Ying again, and the result was such a reward. Li Gang was so angry that he didn't give Li Yuan any face, and directly closed his eyes and closed his mouth.

When Li Jiancheng heard this, he was also trembling with anger. But his cultivation is really good, otherwise he would have gone crazy on the spot. However, Li Jiancheng has also clearly realized since then that his royal father is really jealous of him, otherwise a little Chen should not be treated so harshly.

Li Jiancheng turned around, not daring to meet Li Yuan's gaze, he was afraid that if he couldn't control it, he would fight with Li Yuan.

"Father, this move is inappropriate!"

Shang Shuling and Qin King Li Shimin suddenly said loudly: "Father, Lingzhou has been a battleground for soldiers since ancient times, and now Lingzhou is in charge of the six military governments, but it only has jurisdiction over three subordinate prefectures, but 3,600 soldiers are probably not enough to guard Lingzhou!" ”

Li Yuan nodded and said, "What the people of the world said is extremely true, Lingzhou only has jurisdiction over the soldiers and horses of the three prefectures, which is too few. Then the right guard of the East Palace was reorganized into the Dingyuan Army on the spot, under the jurisdiction of the six prefectures, and Chen Ying was the head of the Dingyuan Army and the Mabu Army. The soldiers and horses under the jurisdiction of the Lingzhou Governor's Mansion have been changed from the original three mansions to six mansions, and the right guard of the East Palace is rated...... Choose a good family in Chang'an and rebuild the right guard rate! ”

Li Jiancheng was shocked when he heard this, and he almost fell. He finally understood Li Yuan's true intentions at this moment.

It turned out to be this strong army led by Chen Ying! Chen applied the soldiers and horses of the 16 regiments of the four prefectures led by the right guard of the East Palace, defeated the four Turkic formations in a row, beheaded more than 20,000 ranks, and captured more than 30,000 Turks, including seven or eight thousand soldiers and horses from Liang Shidu. It's just because the performance of Chen Ying and the right back rate is too eye-catching.

With this kind of terrifying combat effectiveness, Li Yuan really didn't dare to put this uncontrolled army on the couch of Chang'an City. I'm not afraid of 10,000, just in case, if Li Jiancheng has bad intentions and sends troops to counterattack, I'm afraid that the 25,000 troops of the left and right Wuwei in the Su Guard Forbidden (full formation, usually order the left and right Wuwei generals or the left and right Wuwei generals to lead the army, so the establishment of the left and right Wuwei is dissatisfied) is really not able to resist.

There is a way that ginger is old and spicy. Li Yuan was still a chess player in the end, and in a few words, he lightly stripped the elite soldiers of the four prefectures led by the right guard from Li Jiancheng's hands.

……

Due to messaging issues, Chen Ying was not aware of what was happening in Chang'an. Chen Ying was following a group of craftsmen at this time, playing with mud every day, after more than half a month of repeated experiments, Chen Ying finally found this clay under a heavily weathered volcanic rock, although there is no chemical instrument to test the detailed ingredients, after the calcination test, this refractory brick performance is good, Chen Ying guessed that it should be a big luck hit the soil and happened to contain high silicon, so the high silicon refractory bricks were made by mistake.

Solved the problem of refractories.

Chen Ying set fire to the fire and ordered people to start building a blast furnace.

Blast furnace steelmaking is a revolution in industrial history. In the production of blast furnaces, iron ore, coke, and slag fluxes (limestone) are loaded from the top of the furnace, and preheated air is blown from the air outlet located at the lower part of the furnace along the furnace perimeter. At high temperatures, the carbon in the coke (some blast furnaces also inject auxiliary fuels such as pulverized coal, heavy oil, natural gas) and the carbon monoxide produced by the combustion of oxygen in the air are extracted from the oxygen in the furnace, and the oxygen in the iron ore is removed during the rise in the furnace, so as to reduce the iron to obtain iron. The molten iron is released from the iron mouth. The non-reducing impurities in the iron ore combine with fluxes such as limestone to form slag, which is discharged from the slag port. The gas produced is exported from the top of the furnace and used as fuel for hot blast stoves, heating furnaces, coke ovens, boilers, etc. after dust removal.

Before the construction of the blast furnace began, Yang Ze found Chen Ying: "Manager Chen, this ironmaking workshop must not be built outside the city!" ”

"Then according to Yang Changshi's meaning, this blast furnace must be built in the city?" Chen Ying asked with a smile: "But is there such a big place in the city?" ”

"Yes, no, yes! People can be mobilized to relocate! Yang Zeyi said righteously: "The Turks are already short of iron, if the iron mill is built outside the city, it will definitely attract the prying eyes of the Turks, if the Turks can get a large amount of steel in the iron mill outside the city, it will definitely be like a tiger!" ”

The blast furnace was built in the city, and Chen Ying was full of black lines. What kind of brain can come up with such a "clever plan"?

When steel is smelted, a large number of toxic gases will be produced, such as carbon dioxide, sulfur dioxide, manganese and its compounds, chromium and its compounds, benzene and its related compounds, carbon monoxide, trichloroethylene, sulfuric acid, and ammonia. tar, asphalt, etc. These can lead to contact dermatitis and chemical burns to the skin and poisoning with lead and its compounds. For workers who operate the blast furnace for a long time, it is very easy to suffer from silicosis and various skin diseases.

If the blast furnace is built in the city, it means that the people in the city are in a high-dust, high-temperature, and high-noise environment, which means that it is a joke on the lives of the people in the city. What's more, steelmaking requires not only a lot of coal, but also a lot of water. The water source of Lingzhou City mainly relies on karez wells and underground wells, which is not a problem to meet the domestic water of the people in the city, and it is absolutely impossible to supply the huge smelting needs.

Of course, even if the water resources can be satisfied, but long-term smelting will destroy the quality of groundwater, forming serious excess of heavy metals, not to mention the people living in the city now, even the next generation of babies will be affected.

Chen Ying said with a smile: "When making steel, it will consume a lot of water and coal, and the transportation alone is enough to make the whole city vehicles flow endlessly, seriously affecting the travel and life of the people, so it is better to choose a site outside the city to build!" ”

"But the blast furnace is built, and the Turks are pouring troops, so what should I do?" Chen Ying smiled disapprovingly: "With the manager here, why be afraid?" ”

"Manager Chen, you are the right guard of the East Palace, and the main thing is to defend the whole security of the East Palace!" Yang Zedao: "If the imperial court recruits the chief manager and the general manager return to Beijing, what will happen to Lingzhou?" ”

Chen Ying was silent for a moment.

He is the right guard of the East Palace, one of the ten guards of the East Palace, and temporarily led the troops to help Lingzhou, which is a special case. He must be going back to Lingzhou. I am building a lot of construction in Lingzhou, and I am afraid that in the future, I will only make wedding dresses for others.
