After taking notes and managing the Qing Ming House's gains, Ling Xian went into isolation.
Though he calls it isolation, he was actually just enlightening himself with the immortal's inheritances and training himself with the various techniques. After he was done with his isolation, his life became very much relaxed.
Other than what he must do daily, such as enlightening himself and training, he would spend time looking at the mountains, the rivers, and enjoying himself.
When he's free, he would run to the highest peak and stare at the moon and the cloud. If he is really bored, he would drink by himself and sing to the moon.
He felt extremely relaxed and happy with these simple days that were drama free and weapon free.
Plus, he was now the leader hidden behind the Ao Xian House, everyone treated him like he was the mighty God and were treating him with the utmost respect. Thus, every time anyone sees him, they would respectfully greet him with "senior brother."
