The Tang Dynasty's system was usually divided into three levels: "Tao", "prefecture" and "county", which can compare provinces, special districts, and counties in later generations. At the military level, it is collectively called the general manager. The general manager is equivalent to the governor of later generations, and the prefectures and counties under its jurisdiction are different, especially the general manager of Bingzhou (later changed to the governor) and the military affairs of the twenty-four prefectures around Bingzhou.

Chen Ying was in charge of Lingzhou when he was young and was in charge of the military of the six prefectures. In fact, this was a big pit. Fengzhou, which the Tang Dynasty referred to in Fengzhou was not Fujian (Jin'an County), but Nanhengzhou (Wudan Town, Wengniut Banner, Inner Mongolia) was established during the Eastern Wei Dynasty. It was later changed to Fengzhou. However, after being annexed by the Turks at the end of the Sui Dynasty, it was not until Li Jing attacked Yinshan at night in the fourth year of Zhenguan that Fengzhou was re-embedded within the territory of the Tang Dynasty.

Fengzhou now governs the two counties of Jiuyuan and Yongfeng. Shengzhou governs the riverside and Yulin. Xiazhou governs the three counties of Shuofang, Dejing and Ningshuo (all within the Jing border today), Yinzhou governs the three counties of Zhen Township, Conscious and Rulin. Although Suizhou governs the eleven counties and Huazhou governs the seven counties, it was still the territory of Liang Shidu at this time.

Looking at the seven prefectures (including) nominally assigned to Chen Ying, the total number of 34 counties, however, in fact, what can be commanded by Chen Ying are only five counties in 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 the Liang Shidu. In fact, what Chen Ying has got is just a short title.

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

Li Jiancheng was so angry that he shivered when he heard this. However, his cultivation was really good, otherwise he would have gone crazy on the spot. However, Li Jiancheng has since clearly realized that his royal father was really afraid of him, otherwise a little Chen would not have treated him so harshly.

Li Jiancheng turned around and did not dare to look at Li Yuan's gaze. He was afraid that if he couldn't control it, he started to fight with Li Yuan.

"Father, this is inappropriate!"

Shangshu Ling and Qin King Li Shimin suddenly spoke: "Father, Lingzhou has been a place that must be fought for by military strategists since ancient times. Now Lingzhou is in charge of the six prefectures, but only three lower prefectures are under the jurisdiction of the three thousand and six hundred soldiers, which is probably not enough to guard Lingzhou!"

Li Yuan nodded and said, "What Shimin said is that Lingzhou only has the troops and horses under the three governments, which is too few. Then, the Right Guard of the East Palace is reorganized into Dingyuan Army with six governments under the jurisdiction. Chen Ying is the chief general of the Dingyuan Army. The troops and horses under the jurisdiction of the Lingzhou General Administration Office have been changed from the original three governments to six governments. The Right Guard of the East Palace is led by... I chose a good family in Chang'an and rebuilt the Right Guard of the Right Guard!"

Li Jiancheng was shocked when he heard this and almost fell down. He finally understood Li Yuan’s real intention at this moment.

It turned out to be this powerful army led by Chen Ying! Chen used the 16th regiments of the Four Prefectures led by the Right Guard of the East Palace to defeat the four Turkic formations in a row, beheaded more than 20,000 levels, captured more than 30,000 Turkic people, including seven or eight thousand soldiers from Liang Shidu. It was just because Chen Ying and the Right Guard of the Right Guard were so eye-catching.

Li Yuan really dared not put this uncontrolled army in the bedside of Chang'an City. He was not afraid of 10,000, but he was afraid of it. If Li Jiancheng had ill intentions and sent troops to counterattack, he would probably have 25,000 troops of the left and right Wuwei in the guards (full group, usually ordering the left and right Wuwei General or the left and right Wuwei General to lead the army to the expedition, so the left and right Wuwei organization was dissatisfied) and could not resist it.

Youdao is the old man's spicy. Li Yuan is still a chess gamer. He lightly led the elite soldiers of the four palaces to strip them out from Li Jiancheng's hands.

...

Due to the message transmission problem, Chen Ying was not sure what happened in Chang'an. Chen Ying was following a group of craftsmen and playing with mud every day. After more than half a month of repeated tests, Chen Ying finally found this clay under a severely weathered volcanic rock. Although there were no chemical instruments to test the detailed ingredients, after the calcination test, the refractory bricks performed well. Chen Ying guessed that it was a big accident that happened to contain high silicon in the soil, so the high silicon refractory bricks were created by accident.

Solved the problem of refractory materials.

Chen Ying started to build a blast furnace when he caught fire.

Blast furnace steelmaking is a revolution in the history of industry. During the production of blast furnaces, iron ore, coke, and slag-making flux (limestone) is loaded from the top of the furnace, and preheated air is blown from the air outlet located at the bottom of the furnace. At high temperatures, the carbon in coke (some blast furnaces also spray auxiliary fuels such as coal powder, heavy oil, natural gas, etc.) is used to burn carbon monoxide produced by burning into the air. During the rising process of the furnace, oxygen in the iron ore is removed, thereby reducing iron. The refined iron is released from the iron mouth. The impurities that are not reduced in the iron ore and fluxes such as limestone are combined to form slag and discharged from the slag outlet. The generated gas is derived from the top of the furnace and after dust removal, it is used as fuel for hot air furnaces, heating furnaces, coke ovens, boilers, etc.

Before the blast furnace was built, Yang Ze came to Chen Ying: "Manager Chen, this iron smelting workshop must not be built outside the city!"

"So, 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, not, and there are! You can mobilize the people to relocate!" Yang Zeyi said righteously: "The Turks are already short of iron. If the iron fang is built outside the city, it will definitely attract the attention of the Turks. If the Turks can get a lot of steel in the iron fang outside the city, they will definitely be like a tiger!"

When Chen Ying built the blast furnace in the city, he was covered in black. What kind of head was this to come up with such a "smart plan"?

During steel smelting, 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, ammonia, tar, asphalt, etc. These may lead to contact dermatitis, skin chemical burns and poisoning of lead and its compounds. For workers who operate blast furnaces for a long time, it is very easy to cause 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 this is a joke about the lives of the people in the city. What's more, steelmaking not only requires a large amount of coal, but also a large amount of water resources. The water source in Lingzhou City mainly relies on Kaner wells and underground wells to meet the problem of water use for the people in the city, and it is absolutely impossible to supply huge smelting needs.

Of course, even if water resources can be met, long-term smelting will damage the quality of groundwater and cause heavy metals to exceed the standard. Not to mention the people living in the city now, even the next generation of babies will be affected.

Chen Ying smiled and said, "When making steel, it consumes a lot of water and coal. Transportation every day is enough to keep vehicles flowing through the city, which seriously affects the travel and life of the people. It is better to choose a location outside the city and build it!"

"But the blast furnace is built and the Turkic people are coming, what should I do?" Chen Ying smiled disapprovingly and said, "Why are you afraid of having a general manager here?"

"General Manager Chen, you are the right guard of the Eastern Palace. The actual position is mainly to protect the security of the Eastern Palace!" Yang Ze said: "If the imperial court recruits the general manager and the general manager's subordinates to return to Beijing, what should we do in Lingzhou?"

Chen Ying was silent immediately.
Chapter completed!
