Why did Qin Qiong become invisible during the change of Xuanwu Gate? In fact, he was not uninvolved, but had another important task

As long as li Shimin is mentioned, it will be an event that cannot be circumvented by Xuanwumen, and such a topic has been going on for such a long time, of course, the right and wrong in Xuanwumen will not be repeated today. If you look closely, you will find that in this xuanwumen change, Li Shimin has one less person around him, and this person is Qin Qiong, the number one fierce general under Li Shimin.
We know that Li Shimin had two of the fiercest generals of the Tang Dynasty in his hands at that time, Qin Qiong and Wei Chigong. Friends who know this history should understand that in the records of this war, there are many records about Wei Chigong, who not only saved Li Shimin at a critical moment, but also shot Li Yuanji with his own hands. However, there are very few records of Qin Qiong. In this war concerning Li Shimin's fate, Qin Qiong seems to have disappeared, is he not involved in this struggle at all?
During the coup d'état, Wei Chi Jingde was described in a strong color, however, the so-called bravest general of the Qin King, Qin Qiong, was not described, and many people said that Qin Qiong definitely did not participate in the coup. But this is a rumor! According to the Old Book of Tang, on June 4, Emperor Taizong led Sun Wuji, Wei Chi Jingde, Fang Xuanling, Du Ruhan, Yu Wenshihe, Gao Shilian, Hou Junji, Cheng Zhijie, Qin Shubao, Duan Zhixuan, Qu Tutong, and Zhang Shigui equal to Xuanwu Men Jiezhi (Li Jiancheng, Li Yuanji).
In the "Old Book of Tang and the Biography of Changsun Shunde", we find some clues: "In the ninth year of Wude, (Changsun Shunde) and Qin Shubao and others negotiated to build the Yu Dang in Xuanwumen. It turned out that Qin Qiong did not follow Li Shimin into xuanwu gate and kill Li Jiancheng and Li Yuanji, but ambushed outside xuanwu gate to block reinforcements from the Eastern Palace and the Qi Palace.
When Li Shimin ambushed Li Jiancheng and Li Jiancheng with Wei Chigong and others, he also had to worry about his reinforcements, at this time Li Shimin's troops were far from enough to clash head-on, so someone had to guard outside the gate, and Qin Qiong was entrusted with this heavy task, he needed to face a large number of reinforcements, as well as a strong Li Jiancheng's general Xue Wanche.
This Xue Wanche is highly skilled in martial arts, good at using tactics, brave enough to charge into battle, and difficult to distinguish from Qin Qiong. After the outbreak of the Xuanwumen Rebellion, Xue Wanche did indeed bring 2,000 soldiers to the rescue, Qin Qiong and Changsun Shunde and others strictly guarded the death guard, the battle was very fierce, Li Shimin's close confidant Lu Shiheng and others also died in this battle. Later, under the death of Qin Qiong and others, Xue Wanche retreated in spite of the difficulties and prepared to attack the Qin King's Palace instead, hoping to kill all of Li Shimin's family members. Just as qianjun was about to strike, Wei Chigong took the heads of Li Jiancheng and Li Yuanji to show the public, and Xue Wanche and the others saw that the general trend was gone, so they scattered as birds and beasts.
In summary, Qin Qiong played a very important role in the change of Xuanwu Gate, it is precisely because of Qin Qiong's presence that Xue Wanche failed to lead the troops to rescue Li Jiancheng and Li Yuanji in time, if Qin Qiong failed, then the situation would become extremely complicated, and Li Shimin's victory rate would plummet.
