It Isn't Done by a Native Cultivator

Fang Jinyu flipped through the Tianling Sect's manuals and found out that the City of Liches was a stone city. It was as if it had been forged naturally by the heavens and earth, and even a Nascent Soul stage cultivator would find it difficult to damage it. Furthermore, it was divided into two parts, which were the inner city and the outer city.

Currently, the Liches are only living in the outer city of the City of Liches.

In the past, a sect's Nascent Soul stage Grandmaster had once joined forces with a Nascent Soul stage Lich from the City of Liches to explore the inner city of the stone city. However, both of them had mysteriously disappeared.

Soon, the remains of the two Nascent Soul stage cultivators were discovered.
