Capítulo 1107: Too Much Carnage.

Plan B it is then," Drastoic decided. 

Plan B is to talk Ragnarok out of destroying the plane if they can't kill him. They have to switch to it despite the fact that they can kill him. Whichever the reason is for the sudden appearance of a bomb when Ragnarok is near death, it doesn't change the fact that they don't want the plane to be destroyed. 

So they waited for him to regenerate. He didn't disappoint them either. They were afraid he wouldn't be able to recover from having his existence slashed in half. After all, most entities would have blacked out at that point and become meat on the chopping block even if they didn't die. But it seems Danah's observation of Ragnarok's extraordinary regeneration was not baseless. 

But his regeneration still took time. Drastoic found himself complaining after 2 minutes of waiting. 

"How long is this going to take? Do we have to wait and watch him heal like some babysitters?"
