Enemies could emerge from any direction, Su Lun didn't dare to let his guard down.
Suddenly, his ears twitched, hearing some noise.
Like lightning, he swiftly swung around and fired several shots toward the window.
But those shots struck metallic armor, sparking a few brief flashes with a "clang, clang, clang."
In that instant of firing, he saw a figure's "arm" shoot out suddenly, and then grab hold of a roof beam, pulling the figure up to land steadily on the fourth floor.
"An extendable claw? 'Anchor Man' Parker from Knight District?"
Seeing the signature steam-powered extendable claw, Su Lun instantly guessed the identity of the newcomer.
But seeing this person, he was not shocked; instead, he let out a sigh of relief.
He didn't hold back, firing a series of probing shots at the figure. However, over ten bullets later, wherever he hit, sparks flew.
