In 234 BC (the thirteenth year of the reign of King Qin), the Qin army attacked Pingyang (southeast of present-day Ci County, Hebei) and Wucheng (southwest of Ci County) of Zhao again, beheaded 100,000 people, defeated the Zhao army, and killed the Zhao general Hu Xu. After this attack by Qin, Zhao's national strength declined greatly, and he could only retreat to Handan to protect himself.

However, the Qin army did not intend to stop, and in October of the same year, the Qin general Huan Qi led the Qin army east out of Shangdang, crossed the Taihang Mountains and penetrated into the rear of the Zhao State, broke the Zhao army, and captured Chili and Yi'an (now southwest of Yaocheng, Hebei Province).

At the beginning of 233 BC (the fourteenth year of the reign of King Qin), the Qin army entered Handan, and Zhao Wangqian urgently ordered Li Muwei, a famous general of the northern frontier, to lead his troops to the south and command all the Zhao troops to resist the Qin army.

After Li Mu led the main force of the border guards to join up with the Zhao army sent by Handan, he confronted the Qin army near Yi'an. After fierce fighting, the Qin army was defeated. Huan Qi only led a small number of his own soldiers to break out of the siege and rushed back to Qin, which is known as the "Battle of Fat" in history. The state of Zhao recaptured the land occupied by the state of Qin, and Li Mu was named "Wu'an Jun" for this battle.

Although Li Mu defeated the Qin army's troops in the Battle of Fei, Zhao could only protect himself, eliminating the possibility of Zhao aiding Han, and Qin could be regarded as achieving its goal.

After Zhao's power was greatly weakened, Han Wang'an was forced to submit to Qin in 233 BC (the 14th year of the reign of King Qin). In 232 BC (the fifteenth year of the reign of King Qin), the Qin army attacked Zhao in two ways, one army to Zhencheng, one army to Taiyuan, and took Wolf Meng, but then was defeated by Li Mu in Fanwu, known as the "Battle of Fanwu" in history.

Although Qin's attack on Zhao failed, it could not save Korea from a dangerous situation. Qin reigned for 16 years. Korea was forced to cede land around Nanyang to Qin. In September of that year, Ying Zheng sent Nei Shi Teng to accept the land offered by Korea, and he acted as the head of Nanyang Shou, and began to order all men in the Qin State to register their ages so that they could recruit soldiers and conscripts in preparation for a large-scale unification war.

In the seventeenth year of the reign of King Qin, Ying Zheng took advantage of the great opportunity of the great earthquake and famine in Zhao and his inability to help Korea, so he ordered Nei Shi Teng to attack Korea and capture Han Wang'an. Korea perished. The land of the country was set up as Yunchuan County, and the county was established to govern Yangzhai (now Yuzhou, Henan), but Yingzheng's move to order the "unscrupulous people of the world" to be moved to Nanyang caused instability in the homeland of Korea. The state of Qin was once in the predicament of the Xinzheng Rebellion and the defeat of Li Xin.

Naturally, Ying Zheng will not be satisfied with the destruction of Korea. A major earthquake and famine struck Zhao at the same time. It can be said that it is a great opportunity to destroy the Zhao State, so he sent troops on a large scale and ordered Wang Jian and Yang Duanhe as generals. The soldiers were divided into two routes, and the north and south jointly attacked Handan, the capital of Zhao. Zhao sent Li Mu and Sima Shang to lead troops to resist, and the two armies held each other.

Having learned the lesson of the defeat in the Battle of Fanwu, Qin sent spies to bribe Guo Kai, a powerful minister of Zhao, to ask Guo Kai to divide Li Mu and King Zhao. Guo Kai then moved to Zhao Wangqian, accusing Li Mu and Sima Shang of wanting to rebel.

Zhao Wang Qian made Zhao Cong and the generals from the Qi State gather and replace Li Mu as generals. Li Mu's refusal to accept the order made Zhao Wang Qian doubly believe that Li Mu was trying to rebel, so he had Li Mu secretly arrested, executed, and removed Sima Shang from the position of general.

In 228 BC (the nineteenth year of the reign of King Qin), the Qin king Jian army broke the Zhao army, killed Zhao Cong, captured Yan Ju, occupied Handan, Zhao Wang Qian was captured, and the Zhao state was destroyed.

After the capture of Handan, Zhao Gongzijia led several hundred members of his clan to Daidi (northeast of present-day Wei County, Hebei) to clean up the remnants, and established himself as the acting king, heading east to join the army of Yan. As for the Qin army, military operations were suspended and stationed in Zhongshan to prepare for an attack on Yan.

After Wang Jian captured Handan, Ying Zheng personally went to Handan, found the people who had enemies with his mother when he was in Zhao State, buried them all alive, and then returned to the capital Xianyang through Taiyuan and Shangjun.

The remnants of Korea did not become content with the status quo because of the fall of Korea, but on the contrary, anti-Qin remnants were brewing in the area.

Although Han Wang'an did not exile him to a wild land after he was captured, the purpose was to show a tolerant attitude, so as to be gentle with the Korean remnants and show a gesture to the kings of other countries, which was conducive to the defeat of the Qin State, but since the Jing Xuan assassination incident, Yingzheng's attitude towards the six countries of Shandong has changed greatly, and Han Wangan was also implicated, and was forced to leave the Korean mainland in the 20th year of Qin Wangzheng, in order to cut off the connection between him and the Korean remnants.

At the same time, since Korea did not put up a desperate resistance to the Qin state, Ying Zheng only moved Han Wang'an to nearby Yingchen (present-day Huaiyang County, Zhoukou City, Henan Province), leaving a mild surplus.

However, contrary to Ying Zheng's expectations, in the year following Han Wang'an's relocation (the 21st year of the reign of King Qin), the Korean remnants were angry that the country was broken and the king moved, and a large-scale anti-Qin riot broke out in Xinzheng. Although the riots were suppressed, Han Wangan was implicated and died in the Xinzheng riots.

As early as the sixteenth year of the reign of King Qin, when Korea offered Nanyang land, forced by Qin's strong military strength, Wei also took the initiative to sue for peace with Qin, and Qin set up Liyi in this place. At this time, Ying Zheng was mobilizing the main force to attack Zhao with all his might, and he didn't want to disperse his forces to attack Wei, so he accepted the land offering, so that Wei could survive.

In 226 BC (the twenty-first year of the reign of King Qin), Ying Zheng sent Wang Qian to lead a large army to Guguan and capture more than a dozen cities in the northern part of Chu under the pretext that the king of Chu had reneged on his promise to give up the land west of Qingyang (present-day Changsha, Hunan) and attacked the southern county of Qin. After ensuring the safety of the flank of the Qin army attacking Wei, Wang Ji immediately returned to the north to raid and besiege Daliang, the capital of Wei (northwest of present-day Kaifeng City, Henan Province).

The girder dwells in the place where the water is water, the water is water, and the chasm is very wide, and the five city gates are equipped with suspension bridges, and the terrain is easy to defend and difficult to attack. The Wei army relied on the fortifications of Daliang to defend the city, and the Qin army's strong attack was ineffective, and Wang Qian actually led the Yellow River and the chasm (Bianqu) water into the city.

In 225 BC (the twenty-second year of the reign of King Qin), the city of Daliang was flooded for nearly three months, the city wall collapsed, the king of Wei faked surrender, and the Wei state perished. Ying Zheng set up the Wei County in the Wei region, and then built the Surabaya County.

"Qin Dynasty Du Hu Fu, (Shaanxi History Museum collection, unearthed at the gate of the southern suburbs of Xi'an City), the Tiger Fu is a special certificate used by the ancient imperial court to convey orders and mobilize troops.

It is usually made in the shape of a tiger, divided into two halves, the right half of the symbol remains in the Beijing division, and the left half of the symbol is issued to the army stationed outside. When it is necessary to transfer troops, the imperial court envoy will go with the right half of the symbol, and after the army commander will verify the right half of the symbol with the left half of the symbol, the army will act according to the order conveyed by the envoy. ”

The state of Chu is a large country in the south, with a vast territory, dense mountains and forests, and abundant property, and is known to have millions of soldiers. However, the internal affairs of the Chu State have always been sluggish, and the nobles have always competed for power and profit, and this situation was especially serious until the end of the Warring States Period.

Despite this, after the fall of the Three Jin Dynasty, among the only remaining three kingdoms of Chu and Yanqi, the Chu State was the most powerful. The state of Chu also became the biggest stumbling block in the war of unification after the state of Zhao.

The war of Qin to destroy Chu is recorded very briefly in historical records, giving people the impression that the autumn wind sweeps away the leaves, but from the record of the "Chronicle" of "Yunmeng Qin Jian" (also known as Qin Jian of Sleeping Tiger), the situation is not entirely like this, at least the battle of Qin to destroy Chu is quite difficult, and the key figure in it is Changping Jun.

Changping Jun was the concubine of Xiong Yuan, the king of Chu Kaolie, and his father Xiong Yuan returned to Chu to become the queen of Chu, and he and his biological mother stayed in Qin. Because he and Mrs. Huayang belonged to the same Chu royal family, they became the main force of Chu's relatives, active in the political arena of Qin, and joined forces with Yingzheng to quell the rebellion of Chang Yu. After Lü Buwei went to the prime minister, Changping Jun succeeded him as prime minister.

When Yingzheng decided to destroy the Chu state, a court meeting was held, with the main ministers of the Qin state, including Changping Jun, Li Xin, and Wang Qian, to advise on the strategy of attacking Chu (see The Biography of Bai Qi Wang Jian in the Historical Records).

However, Li Xin and Wang Jian had disagreements over the number of troops needed to destroy Chu. Li Xin believed that 200,000 people were needed to destroy Chu, but Wang Jian said that 600,000 people were needed to destroy Chu.

Ying Zheng tended to adopt Li Xin's strategy, because before Wang destroyed Wei, he had tentatively attacked Chu and easily obtained more than ten cities in Chu, so that Ying Zheng came to the conclusion that it was not difficult to destroy Chu. Wang Qian's words were not used, so he excused himself and returned to his hometown in Pinyang to retire. On the other hand, Changping Jun was demoted to Yingchen in the 21st year of the reign of King Qin because he was quite critical of attacking Chu. (To be continued......)
