The Spring Festival of the ninth year of Wude was spent in a festive atmosphere, and the two brothers Kou Zhong and Xu Ziling married the little princess among the four major lords, adding another conversation to the people of Chang'an City. The New Year atmosphere in the people's homes is very pleasant, but the atmosphere in the court is a little depressing. With the decentralization of power by Emperor Li Yuan, after the crown prince Li Jiancheng and the Qin king Li Shimin took charge of the court, they have been fighting in the court many times, and many officials have lost their black gauze hats because of the mutual struggle between the two forces. Everyone came out to be officials, originally for the sake of the black gauze hat on the top, but now it is good that they have been exiled to the frontier because of a trumped-up crime, and no one can stand it, so the atmosphere in the entire court is quite depressing. The Sui and Tang dynasties were not the same as the later Song Dynasty, and the Song Dynasty was because of the sentence of the founding ancestor Zhao Kuangyin, "rule the world with scholars!" ", directly caused the "punishment is not a sergeant doctor!" "What is the emperor used for? The emperor is used to spray, spraying the emperor has become a kind of court, and being convicted because of spraying the emperor has become a kind of merit, and it doesn't matter if he is exiled to the frontier, as long as he is convicted because of spraying the emperor, he will be invited back in a few days. But during the Sui and Tang dynasties, if you were exiled to the frontier, it would be really over, and you wouldn't have to think about coming back for the rest of your life.

Qin King Li Shimin is powerful, so he naturally wants to press the crown prince Li Jiancheng to fight, but unfortunately every time Li Jiancheng is about to be forced into a corner, there is always a force that comes out to stir up the situation, and the situation that was originally crushed by the wind collapses, and Li Shimin is very helpless. Li Shimin saw that this was not good, and it was impossible to say that Li Jiancheng would bring back the headwind situation that day, so Li Shimin decided to send his brother out of this bitter world and go to Elysium to enjoy happiness. Without the banner of the crown prince Li Jiancheng, the Demon Gate Yin Kui Sect naturally has no reason to support it, and those members around Li Jiancheng's banner will automatically disperse, and there will be no obstacle to becoming the throne again. Li Shi thinks so, Li Jiancheng doesn't think like this, every time he is forced into a blind corner by his younger brother, Li Jiancheng is very annoyed, fortunately, there are always inexplicable forces at this time to come out to help him, the problem is that people have to rely on themselves, every time they are rescued by this unknown force, in case they catch up with people and are not available, won't they be finished? The safest way is to send his younger brother to Elysium to enjoy happiness, without his annoying brother, his crown prince position has been consolidated, and the throne is within reach. It stands to reason that in addition to the emperor, the rights of a country belong to the crown prince, but it is a pity that Li Jiancheng feels that he is a very poor prince, even worse than the emperor Li Yuan; Li Yuan was pressed by Li Xiaogong, there is no way to do it, you don't look at what kind of person Li Xiaogong is, there is a difference between immortals and mortals! You, a mortal emperor, are pressed by immortals, is this a shameful thing? Li Jiancheng didn't feel ashamed; But he was a dignified prince, but he was pressed to death by Li Shimin, the prince, which made him feel very embarrassed, and for the glory of the prince, he decided to kill Li Shimin.

In the autumn of the ninth year of Wude, Li Shimin had decided not to be patient, and was ready to ambush his eldest brother at the Xuanwu Gate of the palace and give his eldest brother a ride; After secretly receiving the news, Li Jiancheng estimated the strength of the East Palace side and Li Shimin's Qin Wangfu side, and at the same time decided to give his younger brother a ride in Xuanwu Gate. Well, one side decided to ambush, and the other side decided to pretend not to know, and wanted to fight back.

It was night that the spies on both sides kept busy, and they kept starting to unite their respective forces. The next day, the sky was slightly bright, and the people of Chang'an City were quarreled with the army on the street, and some brave people took a look, okay, the Changlin Army of the Prince's Mansion and the Tiance Army of the Qin Wangfu had already fought each other on the street, of course, the current situation is a little better, the two sides are just holding weapons in the verbal confrontation, and it has not yet reached the point of meeting each other. Of course, if the people are a little more bold and look carefully, they will find that the attention of the generals who take the lead on both sides is not actually on the other party, and the attention of the other side is concentrated in the direction of the palace. Of course, even if there are brave people who dare to poke their heads out to check, before they can check much content, they have already been pressed back by worried parents. So what the people can get is that the Changlin Army and the Tiance Army on the street have already fought each other, and the people don't know why they are fighting each other.

Not far from the palace, is the mansion of some important ministers in the Tang Dynasty, the Changlin Army and the Tiance Army scolded each other, and it was sent to their desks as soon as possible, but unfortunately now they are no longer able to take care of this problem, obviously the two masters are not willing to be lonely, and they decided to fight the changes caused by the results of the first game, and they can only squat in the mansion and wait for news. On the mansion not far from the Xuanwu Gate, the noise from the Xuanwu Gate began to be heard from the side of the Xuanwu Gate from the slight dawn, and it was obvious that this mansion was a smart man, who had already figured out the key to the problem, and closed the door tightly and waited for the result in the palace.

At noon, news came from the palace that the crown prince Li Jiancheng rebelled and was recognized by Li Shimin, the king of Qin, Li Jiancheng had been beheaded by Li Shimin, the king of Qin, at the Xuanwu Gate, and the emperor Li Yuan was frightened by this, and was already sick in bed and could not deal with the government affairs.

Baiguan saw that Li Jiancheng and Li Shimin's brothers won or lost, so they naturally wanted to go to the palace to visit, if they didn't remember Li Shimin now, they wouldn't have to go directly in the future. Of course, in history, Li Shimin's Xuanwu Gate Change, first killed Li Yuanji and then beheaded Li Jiancheng, after taking control of the palace, he summoned hundreds of civil and military officials for the first time, but there were very few people who sounded the seal, that was because the scholars at that time had confidence, they just didn't attend, and Li Shimin didn't recruit them later. The problem is that in the current Tang world, the way of the world has changed, and the powerful ones are no longer the scholars, but the Shangqingjiao, obviously Li Shimin and Li Jiancheng are fighting, and the Shangqingjiao has not stopped it, which can be understood as this is the acquiescence of the Shangqingjiao, since the Shangqingjiao has acquiesced, and now the two have divided the winners and losers, and you still don't come out to stand in line, so isn't it looking for your own death? The head of the Upper Puritan Church said: "Three-legged toads are not easy to find, and there are not many two-legged people!" No matter how hard people fight, it's also their business, and now that the fight is over, you don't come out to wave the flag and shout, isn't this uncomfortable for yourself.

The civil and military officials listened to Li Shimin's reprimand in the palace and didn't mention it, let's talk about Li Jiancheng. In history, Li Jiancheng failed because Li Shimin was desperate, and the Xuanwumen change occurred when Li Jiancheng was unprepared, and Li Jiancheng was caught off guard, and many good cards in Li Jiancheng's hands were abolished. In the world of the Tang Dynasty, although Li Jiancheng got the news that Li Shimin was going to ambush him, after estimating the comparison of his strength with Li Shimin in Chang'an City, he did not pay much attention to it, so he lost unjustly.

Li Jiancheng made several wrong estimates! First, whether it is Fan Qinghui or Zhu Yuyan, although he and Li Shimin are mainly competing for the throne, it is obvious that the forces to which Fan Qinghui and Zhu Yuyan belong will not directly attack him and Li Shimin, after all, he and Li Shimin are also Li Xiaogong's cousins no matter how they say it, and they will directly kill their cousins without their cousins, unless they are ordered by Li Xiaogong; So this caused a strange thing, Li Jiancheng felt that the Yin Kui faction could only rely on itself if it wanted to grow, and if he died, the Yin Kui faction would have no foundation for growth, so in Li Jiancheng's estimation at that time, even if he lost to Li Shimin, there would be a Yin Kui faction to save him from Xuanwu Gate, and when he returned to the East Palace, he could continue to live as a prince, which was nothing more than letting Li Shimin hit his own prestige; However, after he really got involved with Li Shimin, he found that not only did the Yin Kui people on his side not appear, but also Fan Qinghui and others on Li Shimin's side did not appear. It seems that people are just quietly watching themselves and others desperately from a distance.

Second, Li Jiancheng undercounted the elite soldiers in Princess Pingyang's mansion, Li Shimin because Li Yuan's wife died early, Li Xiuning brought it up since he was a child, and he was born close to Li Xiuning, after Li Xiuning married Kou Zhong, Kou Zhong sent more than 100 elite soldiers trained by himself in Luoyang to station near Princess Pingyang's Mansion for Li Xiuning's safety in Chang'an City, although Princess Pingyang has a princess's mansion in Chang'an City, she basically rarely lives, so basically Li Shimin's family, who is naturally close to her, is taking care of her. Naturally, the 100-odd elite soldiers listened to Li Shimin's greeting when Princess Pingyang was away.

Third, Li Jiancheng even undercounted the person of the eldest grandson Wujian, as mentioned earlier, the eldest grandson Wujian ran to the Zhaojun Mansion to take refuge at the beginning, and was ruined by Li Xiaogong in the middle of the night, and later because of Li Chengqian's relationship, he became Li Xiaogong's secret lover, and Li Xiaogong was often not in the Zhaojun Palace, and lived in Zhongnan God for a long time, so the Zhaojun Wangfu slowly became the back garden of the eldest grandson's mother and son. Although Li Xiaogong is not in the Zhaojun Palace, there should be a lot of family soldiers, the family soldiers of the Zhaojun Palace, it can be said that they are the elite soldiers of the Shangqing Ruling Hall, and the eldest grandson Wujian can't command these big-headed soldiers, but her son can! Don't forget that the son of the family can be a disciple of King Zhao Jun.

Therefore, Li Jiancheng undercounted the hidden forces in the Qin Wangfu, although he knew that Li Shi was ambushing him, but he felt that he could win by himself, which was the same as in LOL, two heroes each led a team of small soldiers to fight alone, and he felt that he could win with many soldiers, but he didn't expect that at this time, two teammates of the other party suddenly ran out of the grass, and he was directly beaten to death by the group.

Li Jiancheng's death brought the dispute between Fan Qinghui and Zhu Yuyan to a halt, after all, the core people are gone, what else to fight with Li Shimin! Datang also entered the Zhenguan period at the end of the year.
