"We've got to hurry up and get out of here; the noise might bring the Steam Faction's cadres over."
"Hmm."
Kai helped Su Lun clean up the battlefield, and they prepared to leave.
Just then, Su Lun cocked his ear, noticed something, and grabbed Kai, who was about to head downstairs.
Kai looked at him in confusion, "What's wrong?"
Su Lun shook his head, "Someone's coming from downstairs."
Hearing this, Kai perked up his ears to listen, but apparently, he couldn't hear anything.
"Let's go to the rooftop!"
Su Lun didn't explain further, he set a few cunning mines among the corpses and took the lead upstairs.
Kai, without thinking twice, followed him up.
This decrepit building was familiar territory; Su Lun had already scouted the escape routes during previous visits.
At a distance of fifteen or sixteen meters from the rotten building lay a slightly shorter black building. Reaching it would allow them to avoid an encounter with the Steam Faction members downstairs.
