The Jin Kingdom was surrounded by several large tribes of Jiang Rong. Jiang Rong is a big concept that is widely distributed in the Qin, Jin, Zhou, and northern Chu states. The Jiang Rong in the northern part of the Jin State was originally distributed in the area of Guazhou (Dunhuang, Gansu), but later could not bear the blows of the Qin State, kept moving eastward, and finally had to cross the Yellow River, live under the fence of the Jin State, and became a vassal of the Jin State.

The envoy of the Jin State came to the Jiang Rong tribe and asked the tribe to send troops to assist the Jin army in the battle. The Qin army captured a large number of people and property, and the ranks became very bloated and slowed down, thus giving the enemy time to fully prepare.

At the end of March, the Jin army and Jiang Rong revived. Jin Xianggong was wearing a black mourning dress, Liang Hong was Yurong, and Laiju was on the right side of the car. The Jin army was arranged at the west end of the Kunshan Pass, and Jiang Rong was at its east end.

On April 13, the Qin army reached the eastern entrance of the mountain. Warned by the letter, Xi Qishu had to become cautious, and he proposed that a large-scale and prudent investigation should be carried out first to ensure that it was safe along the way before entering the pass. However, Meng Ming ignored the advice of the Western Beggars, and he only observed the nearby terrain perfunctorily and ordered the whole army to march.

After the Qin army completely entered the ambush circle, it could not avoid the fate of being completely annihilated. When the sun was in the west, the vanguard of the Qin army had already seen the wide mountain pass ahead, and the western begging technique couldn't help but breathe a sigh of relief; Meng Ming turned his head and joked with him; The tension of the sergeants along the way was also relaxed.

Just as people were laughing with each other, thunderous war drums suddenly echoed on the ridge, and the Jin army threw a large number of tree trunks and stones down the ridge, blocking the route of advance in an instant. The chariot couldn't enter the map, Meng Ming drew his sword and jumped out of the chariot, and ordered them to fight. The rear of the Qin army turned and broke through to the east, but Jiang Rong's infantry occupied the eastern end and blocked the entrance with a powerful rain of arrows.

The Qin army was trapped in the mountain road and could not take care of each other; Sergeants were crammed together with prisoners and could not fight; The enemy condescended and shot the Qin people who had no escape. Meng Ming saw that there was no hope of breaking through, the army casualties were getting bigger and bigger, and the enemy's encirclement was shrinking tighter and tighter, so he announced his surrender.

The result of the battle of Kun was: no one in the Qin army could escape, and the horses could not return; The corpses were scattered all over the valley but no one collected them, and the fate of the prisoners of war was different, and the most tragic end was that they were rewarded to Jiang Rong as trophies.

The Jin army returned to Quwo with the three marshals of the Qin army and the brine harvest. The Jin people buried the Duke of Wen of Jin after holding a temple ceremony, and the Jin people changed the color of their mourning clothes from white to black.

Jin Wengong's wife Wen Huan decided to rescue the three marshals, he didn't want to give Jin Xianggong a chance to think, so he found Jin Xianggong immediately after the Wengong Divine Lord placement ceremony.

Wen Ying said: "The three marshals of the Qin army are the main culprits who divide the relations between the two countries, and they are also the people who the monarchs of the two countries want to be executed. But if they die in the Jin state, they will become the heroes of the Qin state, deepen the hatred between the two countries, and make the two countries never have a chance to restore diplomatic relations; But if the three are released, they will become a disgrace to the Qin State, and they will be executed by Qin Jun in the Taimiao, and the relatives of the three will not be spared. So, let Qin Jun fulfill his wish and make their deaths more ugly! Why aggravate the resentment of the two countries for the sake of three sinners? ”

Jin Xianggong was not unaware of Wen Ying's original intention, but on the one hand, he felt that the three prisoners of war were insignificant, and on the other hand, he was full of ** for Wen Huan. He wants to use this in exchange for Wen Ying's favor. Jin Xianggong couldn't refuse her request and immediately released the three of them.

Xianzhen quickly got the news, but he couldn't figure out the intentions of Jin Xianggong, so he hurried to the palace by car and asked Jin Xianggong how to deal with the leader of the Qin army. Jin Xianggong said: "Madame asked the widow to release them, and I have already done what Madame wanted." ”

Xian Zhen was furious: "The enemy captured by Wufu in desperate battles was released by just a word from the woman?!" Damage the victory of the country, fuel the hatred of the enemy, and there is no time left for the country to perish! After speaking, he spat at Jin Xiangong's feet. Only then did Jin Xianggong wake up from his infinite fantasy about Wen Ying, and ordered Tai Fu Yang's virgin father to arrest the three of them back immediately.

After Meng Ming and the three escaped from the city, they knocked down two officials and robbed a carriage. After a day and a night of wild running, the three finally reached the bank of the Yellow River. The three of them saw a small boat on the shore, and an old man was sitting in the boat and fishing with a pole, and Meng Ming shouted, "Master cross me!" ”

The old man didn't reply and said: "I will cross the Qin people, not the Jin people." ”

Meng Ming continued to shout: "We are the Qin people!" I'm Bailishi, next to Shu and C, the one who escaped from the battle of Kun! ”

The old man threw away the fishing rod, stood up, turned around and shouted, "I have been waiting here for many days on the orders of the doctor!" My boat is small, and the three marshals go down the river for five miles, and there is a big boat there that can cross you! ”

The trio continued to run wildly, and finally boarded the ferry before the pursuers arrived. Yang Virgin chased to the river, and when he saw that the ferry had gone from the shore, he untied the horse on the left side of the chariot and shouted: "General Meng Ming, the widow did not practice for you, and I felt rude in my heart, so I specially ordered me to give this war horse to the general, please accept it!" ”

Meng Ming was like a beast that had just escaped from the cage, and it was impossible for him to go back and fall into the trap again. He saluted the other party on the boat and said, "Inheriting the favor of the king of Jin, I did not use the blood of the criminal minister to provoke the drum, and I was able to die in the Qin State." If the widow executes a guilty minister, I will die and not die; If I can be spared with the help of Jin Jun's favor, I will definitely come back in three years to worship the king's blessing! ”

After the three of them crossed the river, they did not dare to enter Yongdu; With their hair scattered and their plain clothes on, they locked themselves in a small house on the outskirts of the city, waiting for Qin Mugong's orders.

Qin Mugong wore mourning clothes and personally led the doctors to the suburbs to greet the three marshals, and he cried and said: "It is my sin to dishonor you by going against Uncle Jian's will, and it has nothing to do with you." ”

Meng Ming asked to be removed from his title. Qin Mugong said: "This is my fault, what is the doctor's crime?" I don't cover up big merits with small mistakes. ”

After the Battle of Kun, the two countries will never be able to survive the "goodness of Qin and Jin" that lasted only nine years; At the end of the Spring and Autumn Period, the Qin and Jin dynasties were in a state of hostility for most of the time, and the Jin State always firmly suppressed the power of the Qin State to the west of the Yellow River. Although the two countries were once allied, they only signed an alliance out of mutual suspicion, and one alliance was only the beginning of another split.

It was not until the Jin State was divided between the Zhao, Wei, and Han families that Qin and the Three Jin Dynasty once again established intricate diplomatic relations.
