In the spring of the third year of Duke Lu Wen, Meng Ming solemnly reported to Qin Mugong that he had trained 40,000 warriors like wolves. Qin Mugong said that he didn't want to be a wolf, but to praise the barbarian; Meng Ming said, there are about 10,000 people like the barbarians! Qin Mugong said, 1,000 people are enough, with 40,000 tigers and wolves, what kind of enemy can't be defeated?

In February, Qin Mugong followed the example of King Cheng of Zhou and summoned the tribal leaders of Xirong and Bai Di to hold a grand ceremony in Qixi. During the Great Serval Ceremony, Qin Mugong announced to the participants the decision to wage a large-scale war against the Jin State, and he asked the tribes to provide the Qin State with war auxiliary troops, servants, and supplies, and asked the leaders of the various tribes to accompany the army to the battle. After the Great Serval Prayer, the chiefs left the hostages and went back to prepare for war.

After the Qin people returned to China, they immediately sent a force to blockade the Longmen Mountain Ferry with Bai Di's army.

On the Jin side, the office quarreled over how to deal with the invasion of the Qin army. Zhao Yu believed that he should stick to the city and avoid the Qin army. This was his claim shortly after the Battle of Pengya. However, Xian Jiju, Yang Virgin Father and others strongly demanded to face the enemy head-on. The two sides were at loggerheads, and no one could convince anyone.

In the end, Jin Xianggong asked the ministers to calm down, and said: "Your opinions have been expressed very clearly, and the widows have heard it very clearly, and there is no point in arguing further. The widow believes that the Jin State is not the only one in the world, and no great country can always win undefeated. The wind did not blow all day, nor did the torrential rain fall all morning; If this is the case in the heavens, how much more is it the state?

"In the four years since the death of the first monarch, the Jin Kingdom has won every battle, the bowstring has been stretched too tightly, and the people are very tired. Qin and Jin were originally rivals, but it was not easy for the Jin army to defeat the Qin army twice. This time, Qin Bo poured the strength of the whole country and personally led the army to attack Jin, and he was determined to win. Even if the Jin people defeated the Qin army with the strength of the whole country, it would be a disastrous victory. What about after the pyrrhic victory? Which country of Chu, Zheng, Wei, and Bai Di will not take advantage of the fire to rob and drive the Jin State from the throne of the overlord? Although the display of force is important, the widow must not destroy the great hegemony established by the ancestors only by the whims. ”

In this way, Jin Xianggong vetoed the opinion of the main battle faction, and ordered all localities to be strictly defended and not to fight; For cities that are not equipped for defense, they organize the evacuation of residents, tear down houses, burn fields, and fill in wells, leaving not a single stitch and thread for the enemy.

At the end of April, the Qin army joined forces with the auxiliary army of the Xirong tribe at Shaoliang City, and then crossed the Yellow River at the Longmen Mountain Ferry. After the coalition forces landed, Qin Mugong ordered the boat to be burned. The Qin people set the ship on fire, and the fire dragon stretched for miles, and the smoke obscured the sky.

Qin Mugong took the crown prince and stood on a high place and shouted: "All people, including the widows, have no way out. If we want to return to Qin, we must advance, we must win, and we must snatch the ships of Jin. The widow didn't leave a way back, so he let the prince stay with him. If I am defeated again, where will I still have the face to call myself a 'Qin person'? If the battle is defeated, let the Qin State perish, and let the living be slaves here! ”

The sergeants were infected by the monarch's momentum and brandished their weapons and demanded battle. After that, the Qin army marched all the way, and encountered no decent resistance wherever it went. Although the Qin people hated the Jin people, they strictly observed the etiquette of war, did not use violence against civilians, did not destroy civilian property at will, and also required auxiliary forces to abide by it.

The Qin army did not march to the capital of the Jin state, because it was better not to attack it if it could not be captured. Both countries know that neither can force the other to submit, let alone destroy the other, through one war or another; All challenges and invasions are nothing more than revenge.

The Qin army crossed the water and surrounded Wangguancheng, which was chosen as the target because it was the birthplace of Xianzhen. The Qin army attacked without delay, and quickly captured the fortified city with the momentum of thunder. The army and people of Wang Guancheng paid a heavy price for the decision of the pioneers.

Although the Duke of Jin Xianggong decreed that it was strictly forbidden to challenge the Qin, in a country where there was never a shortage of warriors, there were still many places where armed forces spontaneously assembled to launch suicidal attacks against strong enemies.

It's just that the Qin army didn't take those dead soldiers into account at all, because the Qin people also had the determination to die. The Qin army usually sent a number of troops equal to the opponent's to counter violence with violence, fight for their lives, and even die with the opponent.

The Qin army took advantage of the victory to march and occupy the suburbs, but the Jin army still did not fight. It was only at this time that Qin Mugong's heart finally landed. He ordered the army to go to Kunshan and swore an oath to seal the bodies of the Qin dead.

The Qin army came to the site of the Kushan battlefield, and the army entered from the east end and traveled west along the route that the Qin army had marched back then. Although four years have passed, the remains of men and horses, rusted weapons and fragments of chariots can still be found everywhere on the ancient road. Most of the wreckage was broken tendons and broken bones, and the heads were different.

Meng Ming, Xi Qishu, and Bai Yibing accompanied Qin Mugong and walked forward silently. Meng Ming really didn't want to recall the past, but he still cried and recounted the scene at that time: the Jin army and auxiliary troops attacked from that direction, that high ground had been fiercely contested, where was the Bao barbarian captured, where he surrendered, where the Jin people built altars, killed prisoners of war and sacrificed to their ancestors. Qin Mugong couldn't help crying, and the sergeants cried.

Qin Mugong ordered the captured Jin people to dig dozens of large pits along the way, and buried the remains of Qin soldiers and war horses and chariots together, and the other victims were buried together, and the burial process lasted for a total of three days.

The Qin people destroyed the altar built by the Jin people, built a taller altar in the same place, and then carried out a solemn and solemn memorial ceremony. Qin Mugong ascended to the height and swore to the Qin army: "The defeat of Kunshan is the sin of loneliness. I would like to warn the whole army here that they must follow the teachings of the ancients, plan great things, and listen to the opinions of the elders, so that they will not make mistakes! After the ceremony, the Qin army crossed the river from Maojin and returned to Qin.
