Fourth Level of Pagoda
Inside the first room of pagoda space, Fei took out the immortal energy and starts Ancient Heavenly God Force Art. The immortal energy entered his body, sucked by his spiritual root. It flows from his supreme meridians and entered his dantian.
He was already at the first stage of Opening Earth Gate Realm, the immortal energy flow into his second origin meridian. This time he didn't convert immortal energy because he didn't need it. The purity of this immortal energy was enough to open all of the Earth Gates hidden inside his meridian.
As for the next realm, he isn't planning to open heaven gate, at least not now. The immortal energy opened the earth gate and slowly moved back to his dantian. All of the immortal energy that was used to open the earth gate also returned to the dantian.
