In the eastern part of Liaodong in the Yan Kingdom. That is, near today's Changbai Mountain. Qin's security trading and other companies encountered a big problem.

The king of the Kei dynasty came to join him. But the security trading company is not a national armed force. They don't know what to do either. They only stated the acceptance of the king's surrender. The State must also be consulted on specific matters. Since there is a huge issue of treatment between the two. So the matter was put on hold for the time being. The security guard, the trading company reported the matter to Meng Tian. And Meng Tian Pegasus reported the matter to Xianyang.

After the Western Zhou Dynasty destroyed the Shang Dynasty, the Shang Dynasty's relict retainer Jizi went to the Korean Peninsula to establish the "Kei Marquis State" with the local natives. At the end of the 3rd century B.C., it was recorded for the first time in the history of Joseon. According to the book "Historical Records" by Sima Qian, a historian of the Han Dynasty in China, Jizi, the uncle of the last emperor of the Shang Dynasty, was at odds with the king of Zhou, and more than 5,000 subjects of his feudal state fled and later came to the northern part of present-day Korea. After the success of King Wu's war, he was named a vassal state, and it was known as "Kei Joseon" in history.

According to the Korean history book "The Remains of the Three Kingdoms", after the descendants of Danjun came to Korea in Jizi, they moved south with their people to avoid conflict with the people brought by Jizi. These people later became the ancestors of Samhan.

Minzi Joseon ruled the Korean Peninsula for almost a thousand years. According to the "Taiyuan Xianyu Family Genealogy", the Xianyu clan of North Korea originated from the descendants of Jizi Joseon. And they started from the Keiko, and went through a total of 41 generations of monarchs, until the 1st century BC was destroyed.

The reason for the sudden annexation of the Kei Joseon stemmed from the Qin security guards, and the trading companies frequently carried out military activities near the Changbai Mountains. They constantly harassed the Kei Joseon. This poses a great threat to the Kei dynasty.

This harassment was devastating, as there was an extreme shortage of slaves in the Qin state. The slave trade became one of the fastest means of making a fortune, and the Kei Joseon was relatively advanced in civilization. The local area has begun to enter the agricultural civilization. The population is relatively dense, and at the same time, there are fixed settlements. It would have been much easier to attack the nomadic tribes. As a result, a large number of security guards and trading companies frantically entered this place.

But with the increase in harassment. The Kei Joseon began to be on high alert, and at the same time began to negotiate with these people. But without exception, all of them were arrested and not released. At the time of the capture of a large number of slaves. The Qin people also found some of the original Central Plains people. The laws of the Qin state clearly stated that it was not possible to use one's own people as slaves, otherwise it would be a felony. So, these people were let go after a lot of screening. All that remains are the local natives. The local natives were also influenced by the Kei Joseon dynasty and began to enter the agricultural civilization.

Therefore, a large number of security guards and trading companies continued to enter the Mini Joseon and frequently attacked these indigenous tribes. The Kei Joseon simply could not organize forces for confrontation. Because, although their size was only more than a hundred, after a slight blow, they immediately gathered several thousand people to take a major retaliatory action. These people's weapons are unusually sharp, and ordinary weapons are difficult to resist. At the same time, it is considered to be the same people. The Kei Joseon decided to annex the Qin state.

The king of the Kei dynasty also realized that unification had become the general trend, and the Qin state began to carry out frequent military invasions. In particular, after the northern minorities were purged, a large-scale invasion of the Kei Joseon began.

The Qin people identified with the Kei Joseon, but not with the local natives. They argued that the local indigenous people were not eligible for an agrarian civilization. Moreover, these natives have a great deal of inertia. They are lazy, they are delicious, and they are constantly running away. Compared to the Xiongnu captured in the north, the Hu people, etc. The shortcomings of these natives are simply too great.

For this reason, farmers in Dongmeng never buy these natives, even if the price is very cheap, they are not willing to buy them. Because they love to run away. No one wants to buy a runaway slave.

For this reason, this will lead to a large number of slaves being unsold. For this reason, a farmer thought of a solution, that is, to use the Xiongnu and Hu people to manage these natives from the Ji family.

The Huns, the Hu people vented all their usual accumulated grievances on these lazy guys. The first day these natives arrived. They would beat them until they killed a group of people. This purpose is to intimidate these indigenous peoples. Make them have a serious fear of it.

Then, it's a matter of putting on different symbols, mainly to prevent it from escaping, and also to wear thick chains. The Xiongnu and Hu people became the objects of their custody. As soon as the natives resisted or were dissatisfied, they were immediately beaten to death. This method immediately attracted the imitation of all farmers. They bought in large quantities of these natives. At the same time, let a small number of Xiongnu and Hu people come to detain these natives.

Due to the hectic harvest season, farmers often arrange a lot of heavy work for these new natives. If you can't complete it, you will be taught a hard lesson. This has led to the mass death of a large number of indigenous people, and at the same time a large number of new indigenous people have come in.

These natives were the ancestors of the later Goguryeo, Koreans. The constant renewal of the natives greatly stimulated the security of the trading companies to point the finger at the Korean Peninsula, which took time and needed to be resolved after the Ki Korean issue.

The slave issue not only stimulated the Qin State, but also the Yan State gradually participated in it, the first time the border army spontaneously participated, gradually. Some of the armies began to take the initiative and the security guards of the Qin State and the trading companies got involved. Together, they attacked the local natives. Because the state of Qin does not accept the same people. Therefore, the Yan people are also very familiar with only attacking the local natives.

At the same time, the army of Yan also began to actively develop northward, that is, today, northern Liaoning, Jilin launched military operations. Capture local tribes as slaves, in the plains it is okay, but once in the mountainous forest area. The Yan army suffered certain losses. And these few tribes will be the future Khitan, Jurchen. At the same time, there are also Xianbei and other ethnic groups that are being formed. Due to the harsh environment in which they live, this also leads to their warlike national nature. But their weapons are extremely backward. After Yan Guo suffered several losses. He immediately turned south. Attack on the indigenous Koreans.

For the Xiongnu in the north. It is severely compressed in the area north of the desert. They will not be able to go south, because they will have to face an inexplicable attack after crossing the desert, and they will be blown up without knowing what happened. At the same time, there is a large number of dense barbed wire. Not only these, but also have to deal with those elusive Qin people. They constantly crossed the desert to harass each other.
