Lin Feng held the fort on Mount Yujing and Mount Yujing returned to the Kunlun Mountains. Although his original body didn't proceed towards the Barren Expanses, his presence continued to affect proceedings at the end of the War of the Two Worlds.
After the War of the Two Worlds approached its end, the rest of the powers in the Divine Lands started to send their representatives towards the Mount Kunlun region.
They were all going to congratulate Lin Feng's eight Immediate Disciples, which had all formed the Immortal soul.
The difficulty of reaching the Immortal Soul Stage was equivalent to the summary of the difficulties of the preceding stages.
Reaching the Immortal Soul Stage also meant that one would become immortal. The world would become entirely different as one crossed the barrier between Man and Heaven.
