The World-Destroying Immortal Venerable

After qualifying for a position in a cultivation sect through his clan's trial, he is cast aside and sent to the worst sect, where he becomes a spirit pet keeper.

I'll take them. Not enough spirit pets? I'll recruit them. Then the world is thrown into chaos, with gods and demons rising together. It turns out it was all planned, a conspiracy targeting me? Raising the broken butcher's knife in his hand, Ye Feng throws back his head and roars, “My fate is mine to command, not Heaven's!”
