In the late night.
Chu Yang sat silently by the lake as he focused his thoughts.
Although nothing had changed, a sword appeared in the lake in front of him.
The sword was inserted vertically into the lake. Even the hilt was covered.
Chu Yang sat quietly as he focused on the sword in the lake.
The sword appeared bent in the water due to refraction. Lights at the Shui Yue garden and the surroundings flickered. The sword in the lake changed its posture at every flicker.
Chu Yang sat quietly as he pondered.
The body of the sword looked smooth as it was made of numerous faces. Each face refracted different light rays.
Different light rays that refracted on the same face gave the same color while another face created a different color. A single light ray that was refracted by the numerous faces created a rainbow!
So that was how it worked.
