Starting from the mouth, the mini Air Bomb slowly descended down to the esophagus and into the stomach.
I figured that was a good enough place to leave a bomb inside.
Next, I need to use the other two mini Air Bombs.
I'm not going to put the rest into the stomach as well. There's a chance that the teleporter might not believe me when I say that there's a bomb inside him that can go off at any moment.
He might just teleport away and die instantly since I can't maintain an Air Bomb when it's too far away. Though he'd be dead, he wouldn't be of any use to me that way.
I need to make him realize that I'm not bluffing. I could control the Air Bomb in his stomach and move it around, poking at the stomach walls, but I don't think that's enough to really instill fear in him. It's just a nagging feeling I have that is telling me it's better to have more options.
