Caishen received information about the attack on his wife when it was over and settled. It was passed to him through a phone call made directly by Bi Cang.
He reported everything, including Majesty farting in the face one of the attackers and Alix putting the bad guys in a box and wrapping them as gifts for Rui Ka Kui.
Most of the anger he felt was replaced with soft laughter at the creativity of his wife. For a moment, it distracted him from his own trouble, the fruitless search of Lai Yanfang.
He was sitting in front of a window in one of the best hotels in the city, watching the Beijing night sky without interest as he debated with himself on whether to call his wife or not. If he called and asked about the attack, would she see it as an invasion of privacy, something like spying on her?
In their last session with professor He, she had mentioned disliking his habit of making decisions for her and then informing her afterwards.
