Jake wasn't crazy enough to think that he had many options in such a scenario. Protecting the world was his mission if that ship was going to leave, then his task was almost complete. However, he disliked abandoning things when they were halfway done. So, he was going to get rid of all the enemies in the spaceship.
"Besides, monsters and other beings invaded Earth on my first life," Jake thought while he enhanced his sword with the dark flames. "I can't excuse my actions, but I can't ignore the fact that their attacks put me on this path. It is time to pay the bill…"
Jake hit the floor below him and began to melt it. It was a bit risky, but he didn't have the leisure to be careful now. He opened a hole big enough for himself, and when the air inside was getting thin, he summoned a crystal wolf. He couldn't think of any other way to close the hole, but it probably would be the best way to keep the hole sealed.
