Xuanwumen is a dead end, whoever enters the game will die, Li Yuanji is already great if he can resist, Li Jiancheng was shot by Li Shimin without even resisting.
Why didn't Li Yuanji kill Li Shimin with three arrows, but Li Shimin was able to kill Li Jiancheng with one arrow?
Li Yuanji, the king of Qi, was not a weak man, he was brave, arrogant, good at using a horse lance, and once competed with another general who was good at using a horse lance, Wei Chi Jingde. After Gaozu Jinyang raised troops, Li Yuanji followed his second brother Li Shimin to fight from all directions, conquered Luoyang in the east, pacified Liu Heimin, and captured Wang Shichong's general Le Renfang, and made many military exploits. Li Yuanji, the king of Qi, went on expeditions with his second brother Li Shimin, the king of Qin, many times, and the relationship between the two gradually became tense in the process, until finally Li Yuanji completely fell to the side of the eldest brother Li Jiancheng, the eldest prince, and the two joined forces to frame and squeeze out Li Shimin.
The Xuanwumen Revolution was a Jedi counterattack by Li Shimin and a well-planned coup d'état. When the Xuanwumen Incident occurred, Li Yuanji, the king of Qi, reacted the fastest, which shows that he knew that there would be a risk of speculation in the palace, so he was equipped with a bow in advance, but when the coup occurred, both of them were in a state of galloping fast horses retreating to the palace. Although Li Yuanji was good at riding and archery, he was highly nervous at that time, and he had to maintain the balance of riding a horse, so it was difficult to maintain his attention, and he was even dissatisfied with the bow, so he didn't shoot Li Shimin three arrows in a row.
Li Shimin is both civil and military, and riding and archery is naturally not a problem, not to mention that he has already prepared, and it is estimated that he has already taken a bow and arrow to prepare when he saw the two of them. Li Yuanji shot three arrows at him in a row, but he didn't shoot back, but accurately shot the arrow at Li Jiancheng, who was in a panic. It shows that Li Shimin's goal at that time was very clear, and he had to kill the crown prince Li Jiancheng.
It was Li Yuanji, after being shot and wounded by the guards led by Wei Chi Jingde and falling from the horse, Li Shimin's horse was also frightened and threw him directly to the ground, Li Yuanji quickly arrived, taking advantage of Li Shimin's fall to the ground and unable to move, ready to strangle him with a bowstring, and at the critical moment of life and death, Wei Chi Jingde rode to come, and the frightened Li Yuanji let Li Shimin go to the Wude Hall to seek protection from Gaozu, and was shot to death by Yu Chi Jingde.
To sum up, the Xuanwumen change was deliberately launched by Li Shimin, so he was not panicked, but Li Jiancheng and Li Yuanji were unprepared, and it was normal for the shooting technique to be inaccurate in the panic. This also fully shows that "first strike is stronger" is always the right choice.
Don't believe that Li Shimin can succeed in becoming the emperor, it depends on luck, it is all fooling. In fact, people rely on strength, and he has been preparing for this moment for many years. This is like many successful people, who say that their success depends on luck all day long, and there is nothing to say. In fact, people work hard in places that people can't see to succeed. It was precisely because of this that Li Shimin was able to seize the throne and create a prosperous era that had no one before or since.
