This is Yu Shiqi's fifth time being reborn in this world. In each of his first four lives, no matter who he was, he ultimately met the same end: being "worked to death" by Gu worms.
So, in his fifth life as a living Gu vessel, Yu Shiqi escapes the dungeon carrying the poisonous insects within him and encounters a thousand-year-old spirit snake. The spirit snake becomes his master, while the Gu worm transforms into a human and claims to be a female general from the fallen Insect Kingdom... To escape the fate of ultimately disintegrating into nothing as a living Gu vessel, Yu Shiqi sets out to find a cure, blending in among a group of orthodox cultivators... But the deeper he gets involved, the more he discovers that the original selves from his first four lives had countless ties to the fallen Insect Kingdom...
[No System + No Romance + Plot-Focused + Slow Early Power Progression; Gu worms and poison are just the entry point, while most of the story focuses on cultivation realms and plot. The realms are: Fufa → Fengshi → Tingzhu → Yinzhen → Tudan → Zhijie → Lianshi]
