As mentioned above, Li Yuan entrusted the recruited heroes to Liu Hongji, Changsun Shunde, and others.
At that time, Li Yuan's recruits were stationed at the Xingguo Temple, the word "Xingguo" symbolized auspiciousness, Li Yuan was very satisfied, and in this process, the Sui Emperor's eyeliner Wang Wei and Gao Junya gradually became suspicious, how could Li Yuan trust the villains of the imperial court?
For example, Liu Hongji, Liu Hongji in his youth personality is relatively extensive, not good at managing family property, and finally the family road fell, he is Yongzhou Chiyang people, his father is called Liu Sheng, once served as the assassin of Hezhou, because of his father's relationship, Liu Hongji served as the third guard. When the Sui Dynasty Emperor attacked Liaodong, he also asked Liu Hongji to follow him, and on the way to the road, Liu Hongji calculated the date and found that his troops could not reach the front line on time, and they were cut off on time, and if they could not catch up, he and his subordinates would have to lose their heads.
When Liu Hongji wanted to go, he ordered his subordinates to openly slaughter the cultivating cattle, and at that time, the laws of the Sui Dynasty explicitly prohibited the slaughter of cultivating cattle for no reason, and he wanted to cover up his major sin by killing the cultivating cattle. Sure enough, he was caught by the magistrate for the crime of killing cattle, and he was sent to prison for more than a year, and finally he was released from prison by means of money redemption.
Another example is the eldest son Shunde, his grandfather was called Changsun Cheng, who was the Qin Prefecture Assassin of Northern Zhou, his father was called Changsun Kai, who was the kaifu of the Sui Dynasty, and the eldest grandson Shunde, like Liu Hongji, served as the Third Guard because of the relationship between the door and the yin. When the Sui Emperor was attacking Liaodong, he was also forced to go, but on the way, he either accidentally broke away from the army, and after breaking away from the Sui army, he ran to Li Yuan, because his niece was Li Yuan's daughter-in-law, Li Shimin's wife, which is also known as the future empress dowager, and because of this relationship, Li Yuan took in the eldest son Shunde as his protégé.
People like Liu Hongji and Changsun Shunde who were disloyal to the imperial court were actually taken in by Li Yuan and let them manage the army, which in wang wei and Gao Junya's view, Li Yuanbao was also a rebel of the imperial court, at the same time, the observant Li Yuan also sensed that Wang Wei and Gao Junya were suspicious of him, in this case, that is, the arrow had to be sent on the string. In May of the thirteenth year of Daye, Liu Shilong, the mayor of Jinyang Township, came to secretly inform Li Yuan that Wang Wei and Gao Junya were planning to send troops to kill Li Yuan when they planned to hold a rain prayer ceremony at the Jinci Temple.
We don't know whether this news was that Wang Wei and Gao Junya really had such preparations, or that Li Yuan had made up information to boost the morale of his soldiers, but this incident prompted Li Yuan to make up his mind: Move!
