The Yu Brother's Case Book - Volume 3 Chapter 4

There is no rebirth through time, and there is no system of heaven to cut melons and vegetables;

There is no secret book under the cliff, and there is no great return pill from the dead;

There is no such thing as a full-fledged lust with a strange root and a sacred blood.

If it is said that Shi Jianren is an expert who has attained the Tao and joined the WTO,

Then Bai Haonan was a dazed fellow who smashed his head into blood.

The key is that he still feels that he is living a very happy life!

A story similar to the golden right foot,

A story about a dream,

It depends on what tinted glasses you are wearing.

Ten or so more years from then, the son would turn into a twisted, evil villain. He would appear in one of the extra chapters to pick on the male and female lead’s children.

Su Ran: Son, you shouldn’t be too outstanding.
Su Han: Why not?
Su Ran: ’cause you will be killed.

Su Ran: Son, would you like to learn music from me and become a zen, little fairy boy who only needs to drink dew.
Su Han: No, I want to go into business so I can support you.
