The Cyan Yuan Sect had nearly exhausted its years of accumulated resources. Naturally, it would need time to recover. Anyone too aggressive would only worsen the sect's situation, and this was the only thing Gu An could do for the Cyan Yuan Sect before he left.
After he left, just like the previous Sect Leader, Liu Xuan, he would no longer be able to manage the affairs of the Cyan Yuan Sect.
Although he wouldn't be dead, joining the Merak Sacred Land meant adopting its identity. He would no longer be purely a member of the Cyan Yuan Sect, and his attitude and actions would inevitably change.
The previous Liu Xuan had been a prime example. When they met again, his priority had been the development of Chiyu Peak within the Merak Sacred Land. One couldn't say this line of thinking was wrong, only that people change once they have made their choices.
