Chapter 670: Chapter 670: The Secret of Ten Thousand Years Ago, Qing Shu Sword Sect's Han Yonghui

The words of the Ancestor of Green-garbed Sword sent a shock through Ye Feng's heart.

This dilapidated Supreme Grade Spiritual Artifact standing on the deserted island was actually the prototype of the Demon-locking Tower?

Could it be that the Demon-locking Towers in the outside world were all created based on this one?

Ye Feng became even more shocked.

He looked at the Ancestor of Green-garbed Sword to inquire about the situation.

"Sect Leader may not know, this matter is related to that great war ten thousand years ago," the Ancestor of Green-garbed Sword said somberly.

Ye Feng immediately became interested.

"Talk about it."

The Ancestor of Green-garbed Sword fell silent for a moment, then said:

"Our Eighteen Ancient Clans were once the overlords of the Southern River Basin, and during our peak stage, we had eighteen Heavenly Emperors at the Void Break Peak."
