The soldiers were not tired of deception, and Gongsun Martin used a trick to capture the Wei generals

In the winter of 343 BC, the Qi generals Tian Ji and Sun Zhen defeated the Wei army at Maling, the Wei prince Shen was captured, and the general Pang Juan was killed by a random arrow.

When the news reached Xianyang, the capital of the Qin state, Shang Martin (Gongsun Martingale) said to Qin Xiaogong: "The two countries of Qin and Wei are either Wei swallowing Former Qin or Qin annexing Wei. Now that the State of Qin has changed its laws and is rich and strong, it can take this opportunity to cut down Wei in order to reclaim a large area west of the Yellow River, occupy the dangerous points of the mountains and rivers, and then go east, one by one, and take over all the princes of the Central Plains, which is the great cause of unifying all countries!" Duke Xiao of Qin greatly praised and sent Shang Martin to lead an army of 50,000 to cut down Wei.

When the State of Wei heard that the State of Qin had sent troops to cut it, he sent his grand duke Gongzi (Yin Ang) as a general and led his troops to resist.

Gongzi Di suggested: "I have a little friendship with Gongsun Martingale, and I use reason to persuade him to make peace without a fight, which is the best way" Wei Huitian was suspicious, but still agreed to let him try.

Shang Martin had already estimated Gongzi Di's thoughts, and as soon as the forwards of the two armies approached, they sent someone to send a letter to Gongzi Di, saying: "We were very good in the past, and now we are generals of the two countries, and I can't bear to attack each other. If you wish, please come to Yuquan Mountain to make a covenant. Gongzi was very happy, and at that time he wrote a reply and agreed to meet on the third day.

On the third day, Shang Martin gave an order, ordering the rear team to retreat first, leaving the front team's men and horses to go hunting in the nearby mountains, while sending people to take musk and give it to Gongzi. Gongzi Ji received the gift and was even more grateful for Shang Martin's affection. Hearing that the qin army had all retreated, Shang Martin only took three hundred guards to wait for Gongzi At Yuquan Mountain, and he was even more relieved. So he also took two or three hundred guards, with wine and food, and sat on the car on Yuquan Mountain.

When he arrived at the venue, Gongzi Di was very happy, and he was the host, first paying tribute to Shang Martingale for three cups. Shang Martin ordered his two warriors, Wu Yu (乌取) and Ren (任鄙) to honor Gongzi Dou (霻). At this time, suddenly the war drum sounded, and Gongzi Was shocked, jumped up from the seat, and said sharply to Shang Martin: "Gongsun Martingale, what is going on, have you lied to me?" Shang Martin sat upright and smiled, "Don't dare, just this time, please don't be surprised."

As soon as Gongzi Di saw that something was wrong, he turned around and ran, and Wu Yu quickly caught up, grabbed Gongzi Di's belt and brought it back. At the same time, Ren Wei commanded the left and right to capture all the soldiers of Wei's retinue alive.

Then, Shang Martin let Wu Yu dress up as a prince and sit on the car, Ren Wei dressed up as an entourage, let some soldiers who surrendered to Wei go to Wucheng first to call for the door, the city saw that it was his own people, he opened the door, Wu Yu and Ren Yi led the Qin soldiers to take advantage of the situation, killing and scattering the soldiers defending the city, Shang Martin led a large group of men and horses to quickly occupy Wucheng.

The State of Wei suffered successive defeats, and the country was very empty and panicked, so it dedicated the land west of the Yellow River to the State of Qin for peace. Since then, the Qin state has occupied the land of Hexi, the mountains and rivers are dangerous, and the country's strength is getting stronger and stronger, laying a favorable foundation for the destruction of the six kingdoms and the unification of the world.
