The next few rooms were almost identical to the first 3 rooms, with the same golden hallway but having 1 more portal each time that Ji Yuan and his group were in a new room.
Another thing that was identical was that the Boundless Sovereign Demon God was always in the canvas above the hallway dome. As for the Great Beyond Goddess, sometimes she was there and sometimes she was not. There was also sometimes the depiction of the other God Immortals as well and when they did appear, it was always a battle between them and the Boundless Sovereign Demon God.
It was relative quick for the first few rooms since Grand Holy Saintess Qi Yuexing and Old Reverend Beiyuan had already been here previously.
After Room 18, it was actually Old Reverend Beiyuan that led the way and he was laughing jovially as he led them through to the right portals in Room 18 and Room 19.
