In the end, he accidentally lost the inner elixir, lost his mana and fainted. When he woke up, he was in the general's mansion. The young general locked her in the study for some unknown reason until that banquet. . It turns out that they had known each other ten years ago. The mountain ghost forgot about it, but the general always remembered it.
