The Immortal Level Thunder Crystals

Although Qingfeng Li was inside the Five Elements Array, he also noticed the five-colored light outside in Fallen Immortal Arena.

He sensed the immortal energy inside the light, which was the authentic immortal energy instead of half-immortal power.

Qingfeng Li had the feeling that this five-colored light was more intense than the light from his Thunder Immortal Sword.

He knew it was a prohibition spell from the desolation era universe cast by Thunder Immortal, the previous owner of Fallen Immortal Arena. It would be activated to protect this space from destruction once half-immortal attacks occurred.

Qingfeng Li operated Heavenly Immortal Chant and sent out his immortal energy to absorb the five-colored light.

He was delighted at the next moment, for he realized he could even take the five-colored light inside his body.
