Blue Star was bustling with noise, but Lu Li had already returned to the Otherworld.
The air, rich with Spirit Mechanism, made his spirit feel refreshed, and he could not help but take a deep breath.
The six Flying Swords that had been stifled for a long time also flew out to revel and play.
They chased and struck each other in the air, filling the mountains and forests with sharp sonic booms.
Their speed had definitely exceeded twice the speed of sound, reaching 700 meters per second!
Moreover, it was not closely related to Lu Li's cultivation level, but rather, it was the innate power of the treasures themselves.
"They must have reached Fourth Grade!"
Lu Li hastily summoned the Flying Swords for a closer examination.
He saw that the blade was still like a pool of autumn water, cold and piercing, emitting a faint Radiance Light, seemingly unchanged.
But upon a closer examination, one could see many dragon-like patterns within the sword body.
