Seven Heroes of the Warring States Period refers to Qi Chuyan and Han Zhao Weiqin. At that time, the world was in turmoil, the Zhou royal family existed in name only, and the princes and states attacked each other. Due to the constant wars, the overall strength of the Qixiongs also alternated in turn. In the early Warring States period, Wei was the overlord, Qi Guoxiong looked at the world in the middle stage, and Zhao and Qin stood side by side in the later stage. From the weak vassal state in the early Warring States period to the later hegemony, Qin Shihuang swept Liuhe and unified China, which was largely attributed to King Qin Zhao.
King Qin Zhao was the monarch of the Qin Kingdom in the late Warring States Period. During his 55 years in power, he continued to expand and expand the territory and erode the six countries of Shandong, gradually forming a situation where the world is weak but Qin is the only strong. The Shandong during the Warring States Period was not the Shandong we are talking about now. The Shandong at that time refers to the east of the mountain range in the western part of Henan Province. At that time, only the State of Qin was on the west side of Qinshan, and the other six countries were on the eastern side of Weishan. Therefore, the six countries of Shandong refer to the other six countries except Qin. Z1z
King Qin Zhao invested a lot of combat resources in the war in order to expand his territory, enhance his strength, and sit on the position of hegemony. King Qin Zhao successively launched 4 large-scale battles against various vassals. All 4 wars ended in Qin's victory, which accelerated the process of Qin's unification of China.
In 293 BC, in order to open the way to the Central Plains east by Qin, General Baiqi led an army to attack the coalition forces of Wei, Han and Dongzhou, known as the "Battle of Yique" in history. After the war began, Wei and Han were unwilling to attack first and waited and see each other. Bai Qi used the characteristics of the two armies to contain the Wei army with a small amount of force, and the main force attacked the Korean army, which was defeated. Then, the Qin Army flanked Wei Jun again, and Wei Jun was defeated and fled. In this war, the Wei-Korea coalition was wiped out by 240,000 people. The two countries ceded their territories and sought peace. Wei's strength was greatly reduced, and South Korea lost its elite.
In 278 BC, the State of Qin launched the "War of Yanying" against the State of Chu. General Bai Qi led his troops to fight the Chu State. He took advantage of the opportunity of Chu State’s city pools not to be repaired, and to prepare for the waste. He even put the Qin Army to death and resurrected. In one go, he captured the Chu State Capital and obtained a large amount of Chu State's land resources, forcing Chu State. Move the capital elsewhere. After the war, the national power of Chu was greatly weakened, while the strength of the Qin army was greatly increased.
In 273 BC, Zhao and Wei jointly attacked South Korea, and South Korea asked Qin for help. The Qin Army adopted unexpected and unprepared tactics, marching hurriedly day and night, and defeated the Zhao-Wei coalition forces in Huayang. Qin took advantage of the momentum to attack Wei, and Wei could not resist being forced to seek peace.
In 260 BC, the "Changping War" between Qin and Zhao was a large-scale and thorough siege. The State of Qin took advantage of the counter-intermination strategy to make Zhao abandon the famous general Lian Po and use Zhao Kuo, who is "talking about soldiers on paper". Bai Qi pretended to be defeated and lured the enemy into deep, forming an encirclement to Zhao Jun in Changping, cutting off his food passage, shooting and killing the main general Zhao Kuo, Zhao Jun was in chaos. Qin Jun killed 400,000 Zhao Jun. After that, Zhao Jun was greatly injured, and he was no longer able to compete with Qin Jun for supremacy.
After these four large-scale wars, the national strength of Qin has been greatly improved, while the strength of the six countries of Shandong has dropped significantly. Of course, according to the situation of the world at that time, it was impossible to destroy the six nations with the power of Qin. Although the Qin State has won consecutive battles, due to years of conquests, the nationals are war-weary, and the treasury is empty, it is also very difficult to use troops in the short term. Although the other six countries suffered disastrous defeats, they were not vulnerable. The main achievement of King Qin Zhao was to formally establish the hegemony of Qin State, laying a solid foundation for the unification of China by Emperor Qin Shihuang.
