In the first year of Chengde, heavy rains in Yongzhou caused the river to burst its banks and flood five counties along the way. However, the disaster relief silver distributed by the court was misappropriated. At the same time, neighboring countries also took advantage of natural disasters and gathered a large number of refugees to invade the border towns as vanguards. They were defeated by their backer Wang Lousheng. Lousheng could not bear to kill the victims, but was slandered by the officials as a way to support the enemy's self-respect. Emperor Mo, who had been wary of the Lou family's army for a long time, was also preparing to get rid of the Lou family. The emperor and his ministers designed to trap and kill the Lou family's army in the name of disaster relief, and massacred the Lou family's father and son. After the Lou family's army suffered heavy casualties, they executed all members of the Lou family for the crime of going unfavorable in the battle, taking credit for killing the enemy, and liaising with foreign countries. After the Lou family's army was destroyed, no one could defend the border town, and it was eventually invaded by the enemy. At this time, heroes from all over the country also emerged. The youngest son of the Lou family who narrowly escaped death, what should he do when he is worried about external and internal troubles? Should he go to another country to learn from Wu Zixu? Or should he choose the Ming Dynasty and change his appearance to defend the country again?
