Capítulo 878: Residual

It had been seventeen days since Su Ming stepped into the chamber.

The chamber was not located above ground, but was within the huge underground palace built under the many towers of the Yu Family. The underground palace had been built tens of thousands of years ago, and it was the most secretive spot in the Yu Family.

At that moment, in the depths of the underground palace outside Su Ming's secret chamber were two gigantic stone flaps of a door that were interlaced with each other to form a ghastly door of hundreds of feet in size.

There were numerous blood-red runic symbols on the door. As they shone in alternating flashes of bright and dark light, a powerful wave spread out from them. In fact, even if a cultivator in the later stage of World Plane Realm attacked at full force, they would find it hard to destroy the door within a short period of time.
