If it weren't for this letter, the sudden departure of Luo Defeng, the leader of Qi Jiao, from the Ashram would have been highly alarming.
Since Qi Jiao's power had vanished overnight in Bowang city and the identity and strength of the enemy remained unknown, as the final Dharmic Needle of Qi Jiao, Luo Defeng should not have acted rashly.
Moreover, the Ashram is the very foundation of Qi Jiao. Even with Cui Yu having the upper hand, undermining it would be a task of many years. The loss of Shang Huaitong, if he were to be killed, would be significant, but still the less damaging of two calamitous options.
Under these circumstances, Luo Defeng's sudden visit to the city forces Tianshan Cui Yu to consider whether the Soul-stealing pearl party requires this grandmaster's intervention for some matter of great importance.
