My Form Is Random After Exploring the Apocalypse

[Every time the protagonist transmigrates to the post-apocalyptic world, the System randomly grants him a transformation, and the transformation's duration is random too. Plot-focused.]

The post-apocalyptic world is a complete wreck. If you're a survivor, you'll have to face hunger and the unknown threat of the Erosion virus. That may be true, but to Qin Yue, this place is where he can make a fortune. Gold and valuable jewels that no one cares about are scattered everywhere. Still, making the trip there and back is no easy feat for Qin Yue. There are countless Erosion creatures, and human nature is even more terrifying than they are.
