Chen headed out of the school campus, as he used the Lightning reflex to travel at the speed of the wind and shadow.
He use the mana stone, which had Lena's magic imprinted on it.
To enter the stealth mode, inside the forest by the side of the road.
Where the haughty boy was moving out on his way to the institution, to get more of the expert teacher inside the group.
To help him clear the shame, while he was planning, how he would kill that boy named Chen. After all, this was the first time, that a boy younger than him had humiliated, him to such an extent.
Just by remembering the scene, he wanted to kill that boy at all costs.
Lost in the thinking of how to torture that guy out, the haughty guy never felt, a boy silently heading from the side window forest.
