'But it's a new land, new monsters, new people, and 'immortals', and sects!' However, another part of him brimmed with excitement.
This mental fight continued for a while.
'You know what? What am I going to lose if I check this out?' Alex had completely forgotten the events that followed when he decided to check out 'things' in Ctesiphon.
"AAAAAAA!" A scream awoke Alex from his trance, and he immediately opened the thick curtains and windows to check it out.
'Maybe they were attacked by ghosts! I need to help these two juniors!' Alex thought to himself as he looked down below.
A young man dressed in white robes was screaming as a slimy creature slid up his arms.
Upon closer inspection, the creature was simply a snail.
The 'Sister' the young man referred to earlier stood on the side, and a palm plastered itself on her face.

Everything will make sense when they reach the Heavenly Domain!
