Qin Qiong's close comrade-in-arms, booby-trapped and killed the number one rebel general of the Wagang Army, and was killed by Li Shimin after defecting to the Tang Dynasty
In the last years of the Sui Dynasty, the world was in chaos, and peasant rebels were everywhere. Seeing that the foundation of the Sui Dynasty was unstable, the clans also rebelled against the Sui. The Wagang army, under the leadership of Zhai Rang, rebelled against the Sui, and under the leadership of Li Mi, a foreign army sprung up. At its peak, the Wagang Army had an army of 300,000 and occupied hundreds of cities.
Zhai Rang raised troops for several years, and the Wagang army has always been a small fight. In just a few months, Li Mi went to the Wagang Army, and the Wagang Army grew rapidly. The reason is simple, because Li Mi's status as a member of the Guanlong aristocratic group is very appealing. Many of the sons of the great clan rushed to Li Mi's signboard to join the Wagang Army. For example, Du Caigan, who was born in the Jingzhao Du clan, came to join the Wagang Army because of Li Mi.

Du Caigan's origin was very noble, he was born in the Jingzhao Du clan of "three feet in the near heavens", and he was of the same lineage as Du Ruyi, Du Fu, Du Mu and others. After Du Caigan defected to Li Mi, he gained li mi's heavy use and became an important general in the Wagang Army. Although Du Caigan's fame was not as good as that of his close comrades-in-arms Qin Qiong and Cheng Yaojin, his position in the Wagang Army was no less than that of Qin Qiong and Cheng Yaojin.
Next to Li Mi, there was a guy named Feng Yuanzhen. Bing Yuan was really the elder of the Wagang Army, and Zhai Rang was a centaur. After Li Mi killed Zhai Rang, he was afraid of causing a mutiny in the Wagang army and had to reuse Zhai Rang's men and horses. Shan Xiongxin, Xu Shiji, And Feng Yuanzhen of the Zhai Rang clan still held heavy troops. These generals of the Zhai Rang clan became the time bomb of the Wagang Army.
Li Mi entrusted Feng Yuanzhen with a heavy responsibility and asked him to guard Luokoucang. Luokoucang was one of the largest official warehouses in the Sui Dynasty, and the grain inside was enough for the soldiers and civilians of Luoyang to eat for many years. Li Mi gave such an important place to Feng Yuanzhen, which was enough to prove that he really wanted to win over Feng Yuanzhen. Unfortunately, Bing Yuanzhen's heart was always not on Li Mi's side.
When the Wagang army fought a decisive battle with the Luoyang army, Feng Yuanzhen secretly defected to Wang Shichong. Feng Yuanzhen sent an urgent report to Li Mi, falsely reporting that Luokou had been attacked by Wang Shichong. Li Mi did not know the plan, and led the Wagang army to the rescue. When the Wagang army crossed the river, Wang Shichong and Feng Yuanzhen attacked halfway.
The Wagang army could not take care of each other, and the result was that the army was defeated like a mountain. Li Mi's main force collapsed, and the other Wagang troops were also defeated. The vigorous uprising of the Wagang Army failed in this way. When it comes to the defeat of the Wagang Army, the number one rebel general, Bing Yuanzhen, is one of the main reasons.
After the defeat of the Wagang army, Li Mi led the remnants of the army to defeat and defected to the Tang Dynasty. Du Caigan gathered the remnants and gathered in the area of Huaxian County, Henan. Wang Shichong and Li Yuan both wanted to win over Du Caigan. Bing Yuanzhen believed that he had a friendship with Du Caigan and took the initiative to apply to Wang Shichong to go to Huazhou to recruit Du Caigan.
Du Caigan pushed the boat along the water and offered a watch to Wang Shichong to ask for surrender. Wang Shichong believed that recruiting Du Caigan, that is, ten to nine stable, sent Bing Yuanzhen to absorb Du Caigan's department. Feng Yuanzhen arrived at Du Caigan's territory and was captured alive by Du Caigan. Du Caigan escorted Feng Yuanzhen to Li Mi's tomb and sacrificed Li Mi with his human head.
