A grayish sword light burst out from the water jar, turning into red halfway through its trajectory, then swiftly changing into deep blue, pure black, pure green, and light green. It was constantly shifting between several colors, giving off a rainbow-like appearance.
Ye Rong's heart shuddered. Although he didn't recognize the origin of the sword light, it was very remarkable just from the aura it emitted.
If he were careless, there was a real possibility that he could be forced out of the stone chamber by this rainbow-colored sword light.
With a flick of his finger, his own two sword lights rushed to meet the rainbow-colored sword light. During the battle, a sharp sword Qi was emitted from the collision that tore his sword lights into pieces. He had to keep retreating, as his sword lights formed circles to gradually contain and weaken the momentum of the rainbow-colored sword light.
