Why?

The slime was able to see everything around clearly.

'Huh? Why did he kill the Dragon King? In that situation, the Dragon King would die sooner or later…' The slime was confused, watching how Theo stabbed the dragon's chest.

However, there were only a few possible reasons. And with how Theo became stronger day by day, it didn't take too long for him to realize that Theo actually had the system. Yes, his system actually remained after the apocalypse.

'How can he even have that system? As expected, it must be related to his secret. Nonetheless, I still have to stop him from reaching the next rank. It will become even more troublesome if he reaches that rank after all.'

The slime understood what he had to do. But before he could attack Theo, another surprise shook the battlefield.

"THEODORE GRIFFITH!"
