By the time Hou Niao had fully recovered, Tideng Monk had already disappeared without a trace, along with Guard Captain Ruan Erjie.
Because of this, Old Man Huang lodged a fierce complaint at his place, accusing the monk of repaying kindness with ingratitude and resenting those who had helped him. Saving him wasn't just Ruan Erjie's effort, but the kindness of the entire Yinyue Castle. To his dismay, not only did the monk leave quietly on his own, but he also took their most capable guard captain with him!
Regarding Old Man Huang's request to pursue them, he just smiled slightly and advised kindly that such things were hard to explain clearly, a waste of words; better left unsaid.
Because he did not want to raise a commotion or hold a farewell ceremony, he despised these superficial acts. So, he chose a night to leave the castle silently. For him, the nights in Yinling were no longer terrifying; rather, he himself was the most horrifying presence in the area.
