Luoyang.

The old land of Luoyi in the Zhou Dynasty in the past changed from prosperity to a piece of weed after more than 300 years of military chaos in the Spring and Autumn Period and the Warring States Period. This big city, known as the Zhongdu Luoyang in later generations, can only be regarded as a small city within the jurisdiction of Sanchuan County, Qin State. The reason why it is because of its county seat is mainly due to its superior geographical location.

When he heard that Li Yuan led his army to come, Yang Xiong and Sima Yin who returned to Luoyang early came out for ten miles. This time, Li Yuan's performance surprised the two hesitant former Sanchuan princess. This battle could actually be so bloody, so domineering, and so heart-wrenching.

Who dares to lead a light army into the enemy city, kill the enemy's heads, and fight against the enemy?

Only General Li.

Who dares to jump on horses and thrust their guns, galloping across thousands of troops, and taking the enemy's head is like taking objects?

Only General Li.

Who can tell the world while talking and laughing, and make all the powerful people flee in a panic?

It's still me, General Li.

"General Li, are you still safe along the way?" Sima Yin was so energetic that he had almost left the army and was now focusing on craftsmanship affairs. Under the recruitment of Sima Yin, Luoyang's craftsmen and craftsmen from various counties in Sanchuan County have gathered craftsmen and craftsmen from Xiping and Handan, and the arrival of smelting craftsmen from Xiping and Handan has made Sima Yin more confident.

Xiping is the smelting capital of South Korea, and Handan is the former capital of Zhao. There are rich iron ore resources nearby. The developed commerce has created a leading smelting technology in the two places. Both South Korea and Zhao have set up iron officials to manage the iron smelting technology and use iron tools as the main production tool. Some merchants who rely on iron tools to make money are directly called iron merchants.

Among the iron merchants who came to Luoyang, Shandong Gong Gong was one of them. Due to the rebellion in Donghai County, Zhuo Gong led his family to the west, hoping to find a place to live. When he arrived in Luoyang, more than 30 people ran out of money. When he saw the proclamation to summon craftsmen posted at the city gate, he became determined to surrender.

The arrival of the Zhuo clan is just a group of many like-minded craftsmen and merchants in Kanto. Their arrival has given Li Yuanjun's craftsmanship system a capital to start: talent.

"Sima Jiang has worked hard. Along the way, I saw a gathering of trade craftsmen, which is much more prosperous than a few months ago. Luoyang has changed a lot." Li Yuan exclaimed sincerely.

"General, come and see, from the west of the city to Luoshui, in addition to the blast furnaces built and smelted by craftsmen, several transport docks were also built on Luoshui. Without long time, Luoyang will not be much worse than Xingyang." Sima Yin was confident. As a city builder and planner, his sense of accomplishment was no worse than being a first-level general. Obviously, after knowing his positioning, Sima Yin devoted more energy to construction and development.

In the changes of a city, the development of heavy industry is the foundation, light industry, and service industry is the auxiliary. Sima Yin did not accumulate as much theoretical knowledge as later generations. His series of actions of recruiting craftsmen, creating weapons and agricultural tools indirectly brought a large number of handicraftsmen to the Luoyang area. The arrival of these people also led to the prosperity of other industries in the city.

The iron smelting process was gradually matured in the late Qin Dynasty and early Han Dynasty. However, compared with the bronze smelting technology that matured to the peak of the Qin Dynasty, the use of iron tools was still in the primary stage. The main constraint on the use of iron tools was the scarcity of raw materials. There were almost no iron ore in the Central Plains, especially the open-pit mineable iron ore. The magic weapon made by meteorite as raw materials was so high that it was so high that it was prohibitive.

Compared with the scarce iron ore, Guanzhong has rich copper ore resources and is buried in the shallow layer of the ground. It is a naturally occurring metal. The favorable mining conditions have made Qin's bronze ware the pinnacle of this era in terms of craftsmanship, flexibility and sharpness.

After verification, the reason why the Qin State's iron smelting technology was not promoted was, on the one hand, because the development of bronze technology, the iron smelting technology was suppressed. After all, one was a mature product and the other was a test product. The risk of choosing unknown products was much greater than that of mature products. On the other hand, it was because the time for the Qin State to be unified was too short, and the emperor Hu Hai was too fucked. The originally strict and orderly craftsmanship system was gradually abandoned in the hands of Hu Hai and Zhao Gao.

Luoyang, a small town carrying Li Yuanjun's hopes and dreams, is also changing itself day by day. Perhaps, one day, it will have a loud name like later generations: Luoyang.

After punching and kicking, Li Yuan finally found a small foundation in Sanchuan County after a lot of effort. This little butterfly has now completed the initial transformation from a pupa to a butterfly, and has begun to flap its wings and take off, dancing gracefully.

February 1, 3rd year of the Great Qin II.

After a little rectification in Luoyang, Li Yuan started the military operation of the Long March Xianyang without stopping. For reasons of confidentiality and suddenness, Li Yuanjun made almost no strong mobilization. He just gave an order and packed his clothes and rushed to the unknown new battlefield.

The six thousand elite soldiers of Li Yuan's army went straight to Hangu Pass along the river. Among the six thousand generals, one thousand cavalry, two thousand crossbow soldiers, and three thousand fully armed infantry. In Luoyang, Yang Xiong and Sima Yin continued to serve as left-behind generals. Together with Hu Zhuang, He Ping, Zhang Fu and others, they took on a lot of miscellaneous work that Li Yuan's army needs to solve but cannot be solved for the time being.

Luoyang, the emerging small city can only serve as the source of its starting point and cannot take on the heavy responsibility of raising a powerful warrior. If everything goes well in the Western Expedition, Sima Yin and the others will follow Li Yuanjun and move to the most abundant hometown of Qin, the Weishuiyuan, which the old Qin people yearn for.

——.

Hangu Pass.

The cart does not have square tracks, and the horse does not have the bridle.

It is located in the plateau in the west, Juejian in the east, Qinling in the south, and Yellow River in the north, "it is named because it is in the valley, deep and dangerous as a bus." The pass is located in a deep and dangerous valley, and only a carriage can be used in the narrow place. In the history of the Spring and Autumn Period and the Warring States Period, Qin State has repeatedly resisted the fierce attacks of the coalition forces of various countries in Guandong with this dangerous pass. The importance of Hangu Pass to Qin can be imagined.

After Qin unified the six kingdoms, the status of Hangu Pass decreased. In the eyes of the First Emperor, the 36 counties of the Qin State must have straight roads, making it convenient and quick to become the main choice for those in power in peacetime. The steepness of Hangu Pass is obviously not in line with this principle.

After the First Emperor's death, the second emperor could not even take care of the Xianyang stall, so he naturally would not strengthen the defense of Hangu Pass. When Chen Sheng's vanguard Zhou Wen entered Hangu and his troops approached Xianyang, Hu Hai and Zhao Gaoshi hurriedly ordered Zhang Han to lead more than 100,000 Xing Tu to make meritorious contributions and finally defeated Zhou Wen's troops.
