Global Superpower, but I Am a Demon

In the first year of madness, creatures mutated. Everyone has superpowers, but he is an ordinary beggar, squatting at the door of a tavern called "Drunk", guarding a broken bowl, and living in the cracks of the wasteland. When the detector swept over him, what others saw was the word "nothing", but what a child saw was the attribute "empty". What is his ability...? The unknown power dormant in the body has become the object of competition among various forces, and is regarded as an experiment subject to be slaughtered. How many hardships do you have to go through in order to survive? What kind of past and truth is hidden in that tavern that always has its door open? The wasteland is ruthless, and only by living can you find the answer.
