A few moments into battle, Leon withdrew a silver needle, preparing to test his next experiment.
After he instilled a very faint trace of Nihility Law into the silver needle, he spread out his divine sense and shot the silver needle at a mutant rat's head.
Swoosh~!
The silver needle quickly shot through the air.
But before it could reach the mutant rat, the power of Nihility Law corroded the silver needle until it was exhausted, causing only the butt of the silver needle to remain, which penetrated the mutant rat's head slightly.
"As expected, the power of Nihility Law is too overbearing, huh? It'll be difficult to imbue Nihility Law into any of my attacks if it only ends up damaging my weapons," Leon muttered with a slight frown.
He could see that the mutant rat had survived with the butt of the silver needle sticking out of its forehead.
Nevertheless, the purpose of his experiment was not to kill the mutant rat but to cure it.
