Xiao Jin, a modern special warfare instructor, accidentally traveled through time and became the deposed prince of the Dayin Dynasty. He was burdened with the curse of the "Destiny Taker" - every time he kills someone, his fate becomes stronger, but he is one step closer to death. He held the cold blade, cut the dragon chair, used violence to control violence, and reorganized the imperial court. Lu Zhaoning, an orphan from the former dynasty who disguised himself as a man, secretly controlled the intelligence network and became both his enemy and his friend. When the imperial power collapsed and the celestial phenomena changed, they discovered that the so-called destiny was just a cage of thousands of years of reincarnation. One person wants to destroy the sky, and the other wants to change his life, but the real enemy is the "soul shadow of the late emperor" who sits on the ninth level and is already immortal.
