Alex fought against Long Jianyu, sending out attack after attack, uncaring of how inefficient his attacks were or how badly he was doing in the fight.
He had a single goal in mind —to kill all the soldiers who were here to kill him or capture him— and he was going to fulfill that goal one way or another. Even if he had to ruin his entire body for it.
Alex and Long Jianyu continued fighting, with Alex always on the losing side, but never actually using. Long Jianyu was must stronger than Alex, but Alex had with him a variety of powers that made it hard for Long Jianyu to easily defeat Alex.
Alex's teleportation was a problem, but it was only a defensive problem and never an offensive problem. He hadn't managed to use his Teleportation skill to teleport into the barrier behind Long Jianyu, and thus the soldiers behind him were safe. Instead, he only used it to dodge Long Jianyu's attacks when it was too hard to handle.
