Without encountering any obstacles, Qin Fengming followed Zhou Chu through a tunnel and entered a Cave Abode deep underground.
Although this Cave Abode lay within a valley, its entrance was inside the palace on one of the mountain peaks.
If they had not searched the soul of the Cultivator surnamed Luan, Qin Fengming and Zhou Chu would never have known that entering the Dark Silence Hall's treasure vault would involve such a situation.
No wonder no cultivators were stationed here. With such a secretive arrangement, even the late-stage Great Cultivators among the Dark Silence Hall's main hall's Ghost Lords probably knew nothing about it.
This was a vast Cave Abode, artificially carved out of the earth. More than a dozen stone doors to cavern chambers stood along its stone walls. Looking at the dense restriction luminescence shining across those stone doors, Qin Fengming could not help frowning.
Judging from the fluctuations of the restrictions on the stone doors, they were all rune restrictions capable of absorbing Heaven and Earth energy on their own. Such restrictions did not need spirit stones to replenish their energy.
To break through such restrictions in a short time, there was only one way: use overwhelming force, an attack stronger than the restrictions themselves could withstand.
