Chương 1639: Contest Over Heaven Form

"Heaven form?!" Fang Yuan was surprised, but soon understood what happened.

Everything was clear now.

Thieving Heaven Demon Venerable was an otherworldly demon, he was skilled in space path and created theft path, he also had great ability in refinement path.

His entire life was dedicated to finding a way to leave the Gu Master world and return to his homeland.

He was the richest venerable, he searched for immortal materials all around the world and refined many Immortal Gu. He had also traveled the most, having explored almost the entire five regions and two heavens.

One day when exploring white heaven, he by chance found a mystical existence, after searching on it, he named it natural heavenly spirit.

Even with his Demon Venerable strength, he could not refine the natural heavenly spirit.

It was not hard to understand this.
