After a period of cultivation and exploration in the strange world behind the mysterious portal, Li Yunfei gained a deeper understanding of this mystical place. The concentration of Spiritual Energy here far exceeded anywhere he had ever been before; with every breath, it felt as though his cultivation level advanced a step further.
He had also gradually mastered the techniques recorded in the Immortal Codex, and the power within his body grew increasingly mighty.

After a moment of contemplation, he decided to follow the rune's instructions and return.
