Cultivation: From Menial Servant to Immortal Venerable

Judging from the aura it emitted, it had astonishingly reached the Tier 4 Middle-Grade!

"It is most likely a descendant of the owner of that demon carcass in the stone chamber!" Zhou Xun guessed.

This demon's form was extremely similar to that corpse, only a size smaller.

"Everyone, attack together. This demon will not be easy to deal with. That strike just now damaged my Black Willow Seal considerably!" Thunder Prison True Lord hurriedly said.

Hearing this, everyone attacked in succession.

Zhou Xun raised his hand and scattered them.

Nine Lightning Seeds flew out, transforming into nine chains of lightning that intertwined into a great net and descended upon the centipede-shaped demon beast!

Profound Thunder True Lord activated his Profound Thunder Avatar and charged straight ahead. The others also unleashed their own methods, attacking the demon beast.

Treasured artifact light flashed, and spiritual radiance of every color danced through the air!

The demon beast seemed to sense the immense pressure from the group as well.

Yet it did not retreat. Instead, it let out an enraged roar. The two antennae atop its head lit up, and in an instant, a lightning shield covered in intricate runes appeared before it!

Boom!

A tremendous crash rang out. It had actually blocked all of their attacks!

The massive aftershock shook loose fragments of stone from all around the chamber.

"As expected of a creature from the thunder prison. It truly is extraordinary!" Zhou Xun secretly praised.

Then he formed hand seals with both hands, firing a thick bolt of lightning from his palm. The others also switched to different methods one after another!

The demon beast remained utterly fearless. Lightning Runes flashed across its body as bolts of lightning counterattacked, colliding with the group's attacks and erupting with dazzling radiance and deafening thunder.
