Chương 538: Chapter 511: Heartbroken Xu Fan

Xu Fan poured the Five Elements Source from the jade bottle.

The Five Elements Source transformed into five long dragons in the air, flying into the solidifying small world.

Instantly, the entrance of the connection channel became smaller and smaller.

However, the residual fluctuations of the battle from the two realms channel became increasingly intense, even threatening the small world.

"Worthy of being the Invincible Venerable, these combat remnants are astonishing," Zhan Ling commented from the side.

"Are you sure you shouldn't be worrying about what to do if this two realms channel doesn't close when the time comes?"

"The avatar jade talisman of the Thousand Spirit Sect Supreme Elder can only sustain for about an hour," Xu Fan said. Though he usually remained calm, at this moment, he felt somewhat tense.

If the avatar of the Thousand Spirit Sect Supreme Elder failed to block the Invincible Demon Venerable, all these years of his hard work would end up in vain.
