Delivering a Visiting Card!

In a quiet room in the Great Light City…

Actually, Lin Feng was still exploring the spacetime prison. Originally, the power of the spacetime prison would almost never change. It was just that in the past, Lin Feng was weak and could only unleash a portion of its power.

Although a portion of its power was already powerful enough, this was an Origin supreme treasure after all. Only experts above the level of advanced Voidwalkers could fully unleash its power.

This time, Lin Feng suppressed the Black-robed Ancestor. In reality, this was also the first time he had gone all out when using the spacetime prison. The spacetime prison after metamorphosis was really extraordinary.

At the very least, if Lin Feng's strength had not increased, or even, if he had not comprehended the principle of spacetime, it would be impossible for him to refine the spacetime prison, let alone control it.
