Chapter 248: Strength Enhancement, Acquiring Engraving Materials (Seeking Subscriptions for Ten Thousand Updates)_2

In Lu Heng's eyes, he had essentially become invisible, his colors merging seamlessly with the wall behind him.

Su Muyu raised her eyebrows, recalled the Chongming Bird, and scouted Lin Zeyu's position, her face revealing a look of surprise:

"This isn't an invisibility effect."

Invisibility effects are created through optical phenomena that make the target appear transparent.

Under the scouting of Perception System superpower users, the effect of invisibility isn't very good.

On the contrary, the effect of camouflage is sometimes better.

For example, Lu Heng used the Illusion Pearl to disguise himself as a Bloodline Demon to enter Black Stone City.

If he had tried to infiltrate Black Stone City while invisible, it would have been nearly impossible.

After all, key entry points such as the city gates definitely have Perception System Bloodline Demon guards.
