Valerian Empire - Chapter 62

I died a virgin right after winning the lottery. Bad luck? That's my brand. So when a Grim Reaper offered me reincarnation with a gacha system for a “second chance,” I should've known better than to trust my luck.I rolled... an orc. The only fat orc in my entire tribe.The dungeon's demon lord gave me three years to lose weight or die. I trained harder than anyone, became stronger than most warriors in my tribe, but my belly stayed huge.With hours left to live, I made the dumbest decision of both my lives: if I'm dying anyway, might as well lose my virginity first.[Virginity Lost! System activated!][Obtain dungeon control upon complete subjugation]Turns out I was supposed to be a DUNGEON MASTER, not a slave warrior. And turns out I've committed the ultimate taboo: interspecies breeding, forbidden across all civilizations. Now I'm a fugitive.Humans, demons, and monsters alike want me dead. My own kind thinks I'm disgusting. I have absolutely nothing left to lose.Time to turn the worst gacha pull in history into the greatest dungeon the world has ever seen.

There is a way in the world here, and the manifestation of the way is a Gu.

When people practice, they cultivate the energy of heaven and earth all over their body to drive away Gu insects and display supernatural powers.

Traveling through a year, Chen Qing finally discovered his specialness on the day he contracted the first Gu worm. He was able to see through everything about the Gu worm…

So, he started to fight steadily, step by step on the road to longevity.
