Why did Wu, the murderer of Peking University's mother murder case, gently remind his relatives to look for the body? What's the purpose?

Wu's family condition is not good, but she is eager to repay her mother. She can't take responsibility for the investment failure with what she has learned, and help her mother and herself to relieve the pain.

Wu has no anxiety or guilt. The reason for this is the following：

First of all, before the murder, Wu had prepared all the tools and applications in advance. This is a typical long-term premeditated murder, and the possibility of impulsive crime can be completely ruled out.

Secondly, Wu Mou's attempt to dismember the body started from the head, because Wu Mou's mother's body only had cutting marks on the head and was almost cut off. Imagine if a guilty person dismembered the body, would you have the courage to cut it from scratch as soon as you came up?

Also, Wu changed his plan in the process of dismemberment, from dismemberment to burial. In the process of ordering plastic wrap and activated carbon, Wu and his mother's body lived in the same room for more than ten days. Do you think a kind-hearted teenager who has been forced for a while can bear such psychological pressure?

Moreover, Wu also set up a camera in the room to observe the situation in the room later. Crucially, the discovery of the body was arranged by Wu. If he is really afraid of being caught, he will let the body be found as late as possible. If your conscience suffers, turn yourself in, or send a text message to express your regret. However, in fact, these normal people don't seem to have any emotions. This is a naked show off, showing his "masterpiece" to the world, expressing his contempt for everyone who has been kept in the dark for half a year, and his absolute confidence in his future escape plan.

The biggest feature of antisocial personality disorder is that there is no sense of morality and guilt at all; On the surface, he is humorous, kind, intelligent and has infinite scenery, but in fact, he is extremely indifferent, and he can even get great happiness from playing with others. So far, this should be the best explanation that can match Wu's series of behaviors.
