Li Shimin has one of the biggest advantages, he was born in the Sui Dynasty, which means that he has the history books of the Eastern Han Dynasty and the Three Kingdoms in his hand, which is the opening of the heavenly eye. It's hard to imagine what kind of flower a master of this level can play with his eyes, but there are too many things that this god stick can do.
Liu Bei began to make contributions in the war against the Yellow Turban Army at the age of twenty-four, and Li Shimin at this age had just exploded Xue Ju, Song Jingang, Liu Wuzhou, Wang Shichong, and so on, if it was Li Shimin's soul at this time, he even had the opportunity to make the world not chaotic in this timeline, and there would be no words to unify the world in this case.
Secondly, in fact, I think the reason why the Three Kingdoms were established is because Cao Cao, Sun Quan, and Liu Bei are all heroic lords and emperors, and if Zhuge Liang really planned the blueprint for the establishment of the Three Kingdoms in advance, Zhuge Liang was the greatest strategist in the Three Kingdoms period.
Although Sima Yi laughed to the end, the pattern and vision were still slightly inferior to Zhuge Liang! Moreover, Zhuge Liang's strategy of uniting Wu against Cao Wei led to the inability of the strongest Cao Wei to conquer any one, and this balance could not be broken, and if his successors continued to strictly implement this strategy, the Three Kingdoms could exist for a long time. This is zhuge liang's strength!
Since then, there has never been a long-term pattern of several political forces on the map of the country, because it is rare to achieve a situation where several elite teams are evenly matched. Moreover, why can't Liu Bei Zhuolu Zhongyuan, because when he bai aided Xuzhou, none of the surrounding forces could defeat them, and when you could defeat Yuan Shu and Lü Bu militarily, you were eligible to compete with Cao Cao for the Central Plains, and Liu Bei's military performance in Xuzhou was too poor.
If it was replaced by Li Shimin, it would be possible to gain a foothold in Xuzhou, and by then the biggest enemy would not be Cao Cao, but Yuan Shao of Hebei. Liu Bei was already a fallen imperial family, the class levels of the two sides were not on the same side, even if Liu Bei made great merits, his achievements would not be recognized by the imperial court, and secondly, when he inherited Xuzhou, Xuzhou itself had already declined in an all-round way, and tens of thousands of people died, and the internal clan and Tao Qian's veterans.
Finally, when liu bang's military geography had been completely changed, the sweat was directly from Guanzhong to Hanzhong, and from Hanzhong to Guanzhong, only need to take a boat, but the Western Han Tianshui earthquake completely cut off Gu Sweat, resulting in the Guanhan Revolution, basically making it impossible for future generations to copy Liu Bang's route out of Hanzhong.
In summary, it can be seen that it is difficult to let Li Shimin take Liu Bei's path better, which is a difficult thing to say clearly. Li Shimin's conquest of Wang Shichong also once formed a wonderful situation of the three kingdoms for a short time, the strongest Li Tang attacked Wang Shichong, and then Wang Shichong and Dou Jiande formed a political alliance to resist Li Tang! The poor thing is that whether it is political wisdom or elite team, Wang Shichong and Dou Jiande are not a little bit worse than Liu Bei Sun Quan's team, and what is even more fatal is that Wang Shichong and Dou Jiande simply do not understand the strategic significance of the alliance against Li Tang, and they are not sincerely united! If Li Shimin crossed back to the Three Kingdoms, he would only be a Cao Cao at best, and he would still not be able to destroy the other two! Li Shimin became Liu Bei does not indicate that Li Shimin became Yuwen Tai, Cao Cao became Gao Huan, and Eastern Wu became the Southern Dynasty.
It is a little difficult to unify the world, although Li Shimin can speak Xianbei language and Xianbei blood, but the Xianbei people who are far away in Daxing'anling cannot support it. Although Cao Shimin was a military system, a three-province, six-part system, and a Guanzhong standard system, but Cao Cao's era was poor in Guanzhong, and at most Li Shimin could reach the strength of his maternal grandfather Yuwen Tai.
Most of the opponents Li Shimin faced belonged to the grass-roots regime, and they perished after a defeat in a battle, while Cao Wei had already established a relatively stable state power, and the financial and military system was relatively complete and mature, so even if it failed several times on the battlefield, it was not enough to threaten the fundamental rule. Therefore, if Li Shimin wanted to destroy Cao Wei, he must fight many battles of the level of defeat, so that Cao Wei's losses would reach the point of shaking the state power.
In addition, the Three Kingdoms and the Sui and Tang Dynasties equipment and cavalry tactics are different, Li Shimin's advantage is the product of the combination of family inheritance and his own talent, you let him be Liu Bei he is estimated to be confused, unless you give him goldfinger or spoilers. Liu Bei is actually a top figure in the chaotic world, and Li Shimin is unlikely to do better than him.
Similarly, Li Shimin's leadership over cavalry in the same era was almost like gongsun zan and cao cao. I think that if Liu Bei had the ability to lead the cavalry in addition to his own qualities as a monarch, he would not have made so many mistakes.
Finally, people often think that the success of the great people in history is a personal factor, but in fact, the objective factor is a larger component. Li Shimin succeeded because he had a group of high-quality officers and excellent soldiers, and occupied the land of Guanlong, which at that time was very favorable to Li Shimin because of its fertile land and strong folk customs.
Add to that his personal abilities to succeed. If liu bei was only replaced by Li Shimin, and he did not have powerful officers and excellent soldiers under him, the land of Bashu was not as good as the land of Guanlong, so it would be difficult for the Northern Expedition to succeed.
