184 Rescuing Yang Xiaojin

Finally, he arrived at the entrance of the tall building.

The firing of the sniper rifle had stopped. It was quite likely that the Experimentals were already up on the roof, and Yang Xiaojin had given up on using the sniper rifle and switched to close combat.

Ren Xiaosu did not choose to take the stairs. He called upon his shadow clone and hopped on its back as it started climbing to the top of the building from the exterior.

Between here and the top, the shortest route was a straight line. If he took the stairs up, Yang Xiaojin would probably already be dead by the time he got up there!

Ren Xiaosu felt some regret. If he had completely copied Luo Xinyu's power, would he have to spend so much effort now?
