Both of them couldn't react to his sudden charge. Before the tall guy shouted, Mark was already in front of him with the mop in his hand swinging at him with full force. The mop went straight for the head, without holding back. The wood broke due to the force, and the man staggered backward. He clutched the now bloody head and kneeled down.
Mark did not stop there as he turned around and kicked the short guy right in front of the cubicle. The force behind the leg was enough to send him towards the wall and drop on the ground clutching his stomach in pain.
Seeing both of their reactions, he felt he underestimated his strength after adapting to the environment. His strength was easily 2 times when he was normal. Still clutching the half-broken mop in his hand, he turned towards the cubicle. Suzie long before stopped crying when she heard the loud noises outside.
Hope you liked the chapter with Suzie's changes. I thought hard about this and this was the best I could think of.
