Lin Xuan succeeded in crossing the border and defeated the frontier general Han Canglan, but the emperor Zhou Jingyan (actually the one who sent Lin Ye to cross) summoned him to the capital to get rid of him. He went to Beijing with a system for summoning heavy cavalry, fought back and entered the palace, but he recognized the emperor because of his "profit". The two discovered that the concubine Xiao Shu who lured them to Beijing was the water ghost who caused them to drown in their previous life, so they worked together to punish her. In the end, Lin Xuan fought in all directions, while Lin Ye stayed at the court, and the two brothers ruled the world together.
