"Actually, I just want something like a guarantee that assures me you're a good guy and that after you finish your evolution, you'll honestly return to your world," Myne didn't want to have too much contact with people from other worlds, especially when they were not only ugly as sin but also powerful enough to kick his ass easily. So, he didn't beat around the bush and got straight to the point.
Apolo, the mutant creature who slightly resembled a hume, fell into deep thought after hearing Myne's condition. After a full minute, when Myne thought the other party was about to take action, he saw him sigh heavily, kneel down, place his tentacular hand on the meaty ground, and a few seconds later, when he pulled out his tentacles, there was an old-looking scroll covered in some kind of stinky liquid.
Dusting the liquid off the scroll, Apolo walked forward, approached Myne, and threw the scroll towards him without saying a word.
