Under Ji Chen's control, two water drills slowly took shape.
He placed his mental focus on them, causing them to rotate and operate simultaneously. Instantly, he felt the difficulty of controlling them increase several-fold.
But he didn't stop at two. After getting used to it for a while, Ji Chen's mind conjured a third water drill, attaching his mental power to it as well, and it began rotating too.
The difficulty increased several-fold once again.
His mental power felt the pressure of having to control three drills at once. One would stop inadvertently, while another would spin too fast.
However, Ji Chen seemed to find joy in this challenge. He worked hard to control them, making them operate at the same rhythm and cooperate with each other.
