Due to a mistake, he was punished by the King of Hanyue Kingdom to guard the mausoleum of Queen Xingyue. While guarding the mausoleum, he met the enemy's ruthless king - Wuqing. As they solved each case, they gradually developed feelings, which made Qingwu gradually become sentimental and fall in love with Yue Mengwu. The leader of the Hanyue Kingdom could not forgive Qingwu for killing his favorite prince Ye Xingyun and did not agree with Yue Mengwu and Qingwu being together, so he severed ties with Yue Mengwu.
Concept: The ruthless food of all things in the world has become ruthless only after being scarred by sentient beings. As long as it is repaired in time, the love song will still be melodious.
