The explosion was so powerful that it blew up the entire house at once, leaving nothing in its wake.
In the distance, Xaen was standing with his hand behind his back, looking at the cloud of fire that was spreading everywhere.
A smirk formed on his lips. "What a waste to use this on a random person. If only Lucifer had personally come, it would've been so much fun."
He turned around. A portal appeared before him. He entered the portal and disappeared with it.
...
Xaen appeared back at the Academy of Gifted Variants, stepping out of the portal that opened in his office.
Grandpa Chi was sitting on his chair, seemingly bored.
"You are back." He stood up, seeing Xaen return. "Finally. I was getting so bored here. Now take care of your chair. It's time for me to leave. Ever since you left me in charge here, I didn't get time to go home. So much dust would have gathered by now."
