The Demon Bone Monk came to a small door, a side entrance that Song Jian had also seen before. It appeared to be merely a thin wooden board, but no matter how Song Jian tried, he couldn't break through it as if some invisible force was protecting it.
There was a keyhole on the wooden door. However, it seemed to be covered by a layer of energy, so even with the Abyss Key, Song Jian couldn't unlock it.
The Demon Bone Monk approached the small door, extending a finger. What had been a fair finger instantly degenerated into a bone spur, and with it, the Demon Bone Monk stabbed at the lock on the wooden door.
Soon, a "click" was heard from within the door, and the Demon Bone Monk pushed the door open, flinging it back nonchalantly and continued forward, seemingly in a hurry to take care of some urgent matter.
