Qin general Shu Changhuan, Qi general Kuang Zhang, Wei general Gongsun Xi, Han general Storm Kite and other four troops attacked Chu, and Chu sent the general Tang Yuan in Fangcheng to resist the armies of Qi, Han and Wei.

The alliance of the Three Kingdoms attacked Fangcheng of Chu, and the two sides lined up in a position with water and held each other for six months. King Xuan of Qi was impatient with the war, so he sent Zhou Shi to the position to urge Kuang Zhang to hurry up and cross the river to fight, Kuang Zhang was unwilling to be wronged, so he said to Zhou Shi: "Kill the minister, remove the minister, and even kill the minister's whole family, this is what the king can do to the minister; When the fighter plane is not mature, it is required to fight, and when the fighter is mature, it is not required to fight, which the king cannot do to his ministers. Subsequently, Kuang Zhang ordered people to find a place where they could cross the river, but because the Chu army released arrows to defend it, the people sent could not get close to the river. Later, a woodcutter told: "It is too easy to know the depth of the river: wherever the Chu army is heavily defended, it is a place where the river is shallow; Wherever the Chu army has few defensive troops, it is a place where the river is deep. Kuang Zhang was overjoyed when he heard this, and immediately selected elite soldiers to cross the river from the place heavily defended by the Chu army at night, launched a surprise attack on the Chu army, and defeated the Chu army at the weesha next to the water. Chu general Tang Yuan relaxed his guard because the coalition army had not moved much for more than six months, and only after knowing that the coalition army had come ashore did he hastily transfer troops to respond to the battle. The Chu army was defeated, thousands of people died, and the Chu general Tang Yuan was killed in battle.

After the Battle of Chuisha, the coalition forces took advantage of the victory to capture a large area of land north of Chuiqiu, Wan and Ye. The lands north of Chu Guowan and Ye were seized by Han and Wei. After Tang Yuan's death, the general Zhuang led the army to mutiny and caused the people to revolt, and the uprising team once captured the capital of Chu and divided the territory of Chu into several pieces.

The alliance between Qin and Zhao broke off diplomatic relations with Qi, and Meng Weijun, the prince of Qi who was the prime minister in Qin, fled back to Qi. Under the initiative of Meng Weijun, the Qi State united with the Korean and Wei States to attack Qin. To Hangu Pass, the Qin army retreated into the pass to defend it. The Three Kingdoms continued to attack, and the allied forces of the Three Kingdoms entered Hangu Pass and occupied the city of Yanshi. The state of Qin sued for peace with the coalition forces and returned Fengling and Wusui to Wei and Han respectively. At that time, the states of Zhao, Song, and Qin were allied and did not participate in the attack on Qin, but Zhao was busy annexing Zhongshan and did not send troops to help Qin. After the Three Kingdoms attacked Qin, the alliance of the Three Kingdoms defeated Yan under the leadership of the Qi general Kuang Zhang. Although the king of Chu, King Huai of Chu, was deceived and detained in Qin by Qin, the allied forces of Qi, Han and Wei defeated the Chu army in the Battle of Chuisha, and Chu did not participate in the alliance.

Although the Qi State was victorious, it did not gain much. Korea and Wei offended Qin and were devastated by the Qin Baiqi in the Battle of Yique.

After the death of King Wuling of Zhao, the state of Qin took the initiative to adjust its relationship with the princes. In the same year, King Zhaoxiang of Qin removed Lou Zhuan, who was trusted by King Wuling of Zhao, and replaced Wei Ran as the prime minister, and took the initiative to reconcile with the state of Chu and aid the state of Chu with 50,000 stone of grain. King Qi adopted Zhu Fu's suggestion to remove the phase of Meng Weijun, who advocated the enemy of Qin, and replaced it with Lu Li, the fifth doctor of Qin. After a series of diplomatic adjustments, Qin and Qi regained friendship. The state of Qi was able to attack the Song state with all its might, while the state of Qin waged war against the neighboring states of Han and Wei to expand their lands. In the same year, King Zhaoxiang of Qin sent troops to attack Korea, Xiang Shou captured Wushi, and Zuo Shu Changbai Qi captured Xincheng.

Under Wei Ran's recommendation, Bai Qi was promoted to the left guard and replaced Xiang Shou as the main general. In the same year, the combined forces of Han, Wei, and Eastern Zhou, with the Wei general Gongsun Xi as the main commander, led troops to Yique to confront the Qin army. In the war, the strength of the Qin side was less than half of the combined forces of Han and Wei, and the Korean army was weak on the side of the coalition army, hoping that the Wei army would take the initiative to attack, while the Wei army relied on the elite of the Korean army and wanted the Korean army to take the lead. Bai Qi, the commander-in-chief of the Qin army, took advantage of the weakness of the combined forces of Han and Wei to retain their strength, blame each other, and refuse to fight first, first set up suspicious troops to contain the main force of the Han army, and then concentrated his forces to attack the Wei army by surprise. After the defeat of the Wei army, the Han army was defeated and fled, and the Qin army pursued the victory and won a great victory. In the Battle of Yique, the Qin army beheaded a total of 240,000 people, the Qin army occupied Yique and five cities, and the Wei army's main general, Gongsun Xi, was captured and executed. After the war, Bai Qi was promoted to national lieutenant for meritorious service. In the same year, Bai Qi took advantage of the disastrous defeat of Han and Wei in the Battle of Yique to lead his troops across the Yellow River and seize a large area of land east of Anyi to the Qianhe River.

In 329 BC, Dai Yan took the throne of the Song State by force, and his brother Song Jue Chengjun fled to the Qi State. In 318 BC, Dai Yan established himself as king. Later, the Song Dynasty went east to attack the Qi State and captured five cities; defeated the Chu army to the south and expanded the land for more than 300 miles; Defeated the Wei army to the west, captured the second city, and had a grudge with Qi, Wei, and Chu from the beginning. Wang Yan of the Song Dynasty attacked and destroyed the Teng State and the Xue State, and the national strength reached its peak, and it was called the "Song Dynasty of Five Thousand Times". However, the king of Song was tyrannical and arrogant, shooting the sky with a blood bag to demonstrate and subduing the ghosts and gods, being a drunkard and lustful, and shooting and killing the ministers who advised him, and the princes called him "Ji Song".

On this day, the king of Song sent an envoy to Longcheng, and the king of Song asked Long Hui to pay all the Longcheng and the surrounding ten cities to the Song state, and also sent Xi Shi and Zheng Dan to the Song state to serve the king of Song, otherwise he would slaughter the dragon city. When Long Hui heard this, he immediately ordered his subordinates to drag the Song envoy down and behead him. I recuperate, you, the blind King of Song, really want to die. Pang Juan, you led the first, sixth, nineteenth and twentieth armies to the Song State, and the Song State would not be destroyed. Pang Juan led the troops and set off,

At the same time, the king of Qi wanted to destroy the Song state in order to facilitate the expansion to the Central Plains, and the king of Qi sent the general Han Nie to raise troops to attack the Song state.

Pang Juan asked the First and Sixth Armies to use shields and chariots as the first attack, followed by the Nineteenth and Twentieth Armies, and the Song army resisted stubbornly at first, and after being wiped out more than 10,000 people, they began to scatter and flee.

The people of the Song Dynasty suffered for a long time from the abusive government of the "Song Dynasty", and the people's hearts were scattered and the city was not defended. Pang Juan and the Qi army were able to quickly break through the capital of the Song Kingdom. Song Wangyan was killed, but Qi's destruction of Song not only exacerbated the contradictions between Qi and Qin and Zhao, but also posed a serious threat to Han, Wei, and Chu, resulting in extremely acute contradictions between Qi and other countries.

The Qi State once took advantage of the rebellion of the Yan State to enter and occupy the Yan State, but due to the corruption of military discipline and the plundering of the people's wealth in the Qi army, the Yan people rebelled, and soon the Qi army was forced to withdraw under the pressure of Zhao, Wei, Han, Chu, Qin and other countries. Later, the Yan State took advantage of this situation to actively act and formed alliances with other countries. Yan general Le Yi led the armies of Yan, Qin, Han, Zhao and Wei to attack Qi, and rebelled against the Chu general Naoya in the name of saving Qi.
