Reincarnated as an Energy with a System - Chapter 216: Only an Invoker

In the ancient land of Yamato, seven powerful clans rule, each upholding their own traditions and strength. But when one clan seeks forbidden power, the balance of the world is shattered. Legends tell of warriors destined to rise, of a hero who will walk the sacred path, and of a battle that will shape the future of Yamato. As alliances are tested and enemies emerge from the shadows, the line between justice and power begins to blur. Will strength alone decide the fate of Yamato, or will a greater force change its destiny forever?

Yo, Hi! I’m Frank, I made a deal with a demon to pay me some money for receiving a guest for a few days every week.

On May 8th, Bruce Wayne ‘Batman’ came to me. I was forced to follow him to fight crime.
On May 16th, Hannibal Lecter, The Silence of the Lambs, came to my home. I can only say that I really can’t stand my guests.
