Wei and Han, out of their own interests, did not want the Yan State to perish the Qi State, so Tian Dan recovered 72 cities and sealed Anpingjun, but the Qi State did not perish. Although the task of destroying Qi was not completed, Qi withdrew from the ranks of competing with other countries during the Warring States Period after the Five Kingdoms.
In 283 and 24 BC, Zhao Haoqi of Qin continued to attack Wei. At the same time, Zhao Haoqi of Qin asked Zhao for harmony, claiming to exchange 15 cities. During this period, the story of returning to Zhao in perfect condition, which was discussed in the history of China, was born (details are not discussed here). In 282 BC and 28 BC1year, Qin attacked twice and Zhao captured three cities. In 280 BC, in the twenty-seventh year of Xiang Gong in Zhao Haoqi, the State of Qin sent general Sima Cuo to attack, and the State of Chu forced the State of Chu to cede the land north of Hanshui River to the State of Qin for peace. In 278 BC, in the twenty-ninth year of Qin Zhaoxiang, the State of Qin sent a general to attack the State of Chu, but he returned in vain and captured the capital of the State of Chu. Chu's army collapsed at the touch of a button, so it couldn't fight any more. It moved its capital to Qiu Chen, which was called the Battle of Yan Yong in history.
? From 279 BC to 278 BC, the famous soldier of Qin led an army to attack Chu, which broke the capital and capital of Chu and dealt a heavy blow to the main force of Chu army. In the war, Tian Lei chose the best time to send troops and March route, and gained the strategic initiative to attack Chu. Qin Jun fought alone in the territory of Chu, hoping to live to death. While the city of Chu was not repaired, he took the opportunity to relax. He conquered Yancheng, the other capital of Chu, by breaking the water and attacking the city, and went deep into the territory of Chu along the Yangtze River, capturing the capital of Chu and achieving great victory. After this war, Qin gained a lot of territory of Chu. Chu was forced to move the capital, and its national strength was greatly weakened.
In the 20 years after the war, Chu was unable to confront Qin, and ensured the security of the southern border on the road of continuing winter storage.

? After ensuring the security of the southern border, he led an army to attack Wei in 276 BC, forcing Wei to cede several cities to Qin. In 274 BC, Wei Ran, the prime minister of Qin, attacked Wei again, beheaded tens of thousands of enemies and forced Wei to cede a large area of land. In 270 BC, Qin had gained great advantages among the six countries, and its territory was the widest among the seven countries. The king of Qin was eager to compete with Zhao. Since the five kingdoms were cut, Qi declined and found a corner of peace. The south attacked Chu, and Chu moved the capital to protect himself. Han and Wei were attacked by Qin one after another, and their strength was weak. Looking at the six countries, only Qin can compete at this time. In 270 BC, Qin and Zhao fought a great war with it, which was called the battle with it. In the temple of Zhao, Lin Xiangru, the prime minister of Zhao, recommended Zhao She, a general of Zhao, to lead a great army against Qin. General Zhao She fought many battles, and defeated the menacing Qin Jun with the plan of suspected soldiers. Eighty thousand troops were wiped out, and Qin suffered the worst defeat since the Battle of Hexi. Lu thought that Qin would retreat, but the king of Qin didn't give them a break. In 268 BC and 266 BC, Qin continued to attack. In 4 1 year, Xiang of Qin State was appointed as the Prime Minister, and through his appointment, the aristocratic parties of Chu State in the temple of Qin State were eliminated. After 4 1, Xiang finally gained absolute control over Qin. He boldly adopted the strategy of attacking from afar and attacking from near, and made an alliance with Qi in the East.
? In 263 BC, Leitian was ordered to lead an army to attack South Korea, cutting off the connection between South Korea's New Deal and Shangdang in the north. Under the pressure of the king of Qin for millet, Wang Han agreed to cede Shangdang County to the State of Qin. However, in order to prevent Shangdang from falling into the hands of Qin, Shangdang county guards turned to Zhao for help and gave Shangdang county to Zhao. At this time, Zhao can be described as triumphant and effortless, and gained many cities. However, when Zhao took over this hot potato, Qin's anger would all be vented on Zhao, and a battle to determine the historical direction of the Warring States would soon break out. It was the battle of Changping, which was regarded as a classic battle by China militarists.
