"Hey, are you here to subdue the immortal serpent too?" a familiar voice called out from behind, prompting Xi Mu to turn his head and look.
The newcomer was a one-armed swordsman, wearing a tattered cloak, with one hand resting on his katana, and donning a wide-brimmed hat.
He tilted his head slightly, revealing a face full of scars beneath his hat.
"Why not travel together since we're both human?"
"You don't know your way around, do you? You're looking for someone to guide you?" Xi Mu seemed to have instantly seen through the one-armed swordsman's real intention.
"Hahaha... Is it that obvious?" the one-armed swordsman laughed sheepishly before he frankly admitted.
"I'm indeed not too familiar with the rules of the underground world." He pointed at a train station not too far away, and at a train traveling along a river of magma.
"Thinking about a vehicle traveling on a river of fire is strange, isn't it?"
