Su Lun didn't linger at the position in the alley, instead, he turned and made his way to a nearby dilapidated building.
Inside the building there was no light, only darkness.
Although he knew the enemy had already ascended the building, he guessed that there must be traps, cunning mines, or alarm devices scattered along the way.
After all, this decrepit building was a regular gathering place for the people of Green Street, and its layout was etched into their minds.
Therefore, Su Lun didn't choose to take the stairs but instead used the mechanical grappling gloves on his arms to shoot steel wires, clinging to the external obstacles and climbing up the outer wall until he reached the rooftop.
Not seeing anyone on the rooftop, he listened closely for a moment, then descended to the fourth floor.
Rappelling down to the fourth floor with the steel wire, he landed in a corner and observed two figures stealthily setting up a sniper rifle.
