The door of the library started shaking as the staff exploded with the power of lightning.
The attack failed, but the Thunder Emperor didn't feel disappointed. He was merely assessing how strong it was.
"Whew~ That was tough…" He said as he stepped back a couple of times.
In the meantime, Charles frowned at his action as the sparks of lightning almost reached him. He had to move to avoid being hit by the staff's lightning power.
Charles grunted at this as he shifted his attention to Jean.
"Aren't you going to stop him from destroying the door? I can tell that there are many students hiding behind that door. Once it's opened, many students will be injured if you let him be." Charles said to Jean as he held his cane tightly.
Charles knew that his movement was already slow. In terms of movement speed, he would fail compared to the person in front of him.
