As Hao Ren heard Y'zaks, something sprang to mind. He looked at the obsidian outcrops around him as asked, "Is it the type where you put a few obsidian in the center and light it up?"
"What are you even on about?" Y'zaks wasa genuinely confused.
Lily headbutted Hao Ren away as she chirped, "Oh ignore him. He's derping out again. Say, big guy, how are you going to create a portal towards the human realm? Didn't you say that it's difficult for demons go into the human domain? There's like many obstacles and sensors..."
"Humans have set up a very tight network of spatial surveillance as the first line of defence against teleportation magics by the demons. That aside, the demonic plane is also in the deepest depths of the spatial bubble, and made things very difficult for demons to head towards the human realms." Y'zaks laughed, "But I had visited there long time ago, and have left some 'pathways'."
