Chapter 1667: Day of Tribulation Transcendence

The Heaven Fey Ancient Ruins's Fey Altar was not inside Heaven Fey City, but in a mountain valley west of the city. It was the bedrock of the Heaven Fey City's establishment.

Legend had it that billions of years ago, the Fey Altar was the core of the forbidden zone known as the No Return for Thearchs. After it was leveled by a peerless Fey Patriarch, he established the Fey Altar at the core. While suppressing the forbidden zone, he also focused the Heaven Earth Yuan Qi of the nine dragon veins beneath it.

Since time immemorial, this zone had an unparalleled allure to the Fey. It attracted countless powerful Fey to experience Nirvana here.

When Yi Yun stepped into this land, he sensed the rich vital powers that emanated the area.
