Tomb Raiding: I Become a Gu to Overpower the Nine Gates and Win Eternal Life

[Tomb raiding + no System + Gu medicine + fighting poison with poison + biological modification + Republican-era underworld + ruthless decisiveness]

I'm Xie Yan, the Yan in insatiable greed.

Other people go tomb raiding for treasure. I go because I'm hungry and want to find something to eat!

Xie Yan transmigrates to the Republican era and becomes the sickly young master of the Xie family, one of the Nine Gates.

From the start, his second uncle, Lord Xie Jiu, the smartest man among the Nine Gates, is infected with corpse poison. The family is in turmoil, with warlords eyeing them from outside and traitors stirring trouble within.

Fortunately, Xie Yan awakens the Myriad Gu Origin and devours a Corpse Beetle King, refining [Blood Immune to All Poisons]!

He refines a Six-Winged Centipede and forges [a Vajra Iron-Bone Body]!

He devours the blood of an Angry-Eyed Rooster and manifests [Golden Demon Eyes]!

He fuses with a Huo family's Undying Worm and achieves [an Immortal Regeneration Body]!

Qiongqi? Eat it! Qilin? Eat it! My maternal grandmother's bloodline is Taotie!

Years later, when everyone else speaks of forbidden lands with terror, Xie Yan stands before the bronze gate and says, “Whatever's in there must be really nourishing.”
