347 is very lively.

This time, Otto did nothing to the Blood Thunder Lord, and they peacefully went their separate ways.

He reached a simple agreement with the Blood Thunder Lord, promising to let him go and treat him as if he were invisible.

No matter what the Blood Thunder Lord did next, Otto was not allowed to intervene, even if he was wreaking havoc on the world.

In return, the Blood Thunder Lord gave Otto a simple piece of information.

About the secret of the light ball in his brain, Otto was told he could go to the Land of Red Flames, a place filled with demons, to find a powerful flame demon known as the Demon Flame Emperor.

The Blood Thunder Lord provided Otto with minimal information, merely revealing that Otto's power came from a powerful Demon Lord.

As for the Demon Flame Emperor, he was one of the Demon Lord's capable lieutenants.

If he wanted to discover the secret of the light ball inside his brain, it seemed that he had no choice but to visit the Land of Red Flames.
