After learning that the birthday gang was robbed, the court was very angry and issued an order to arrest the robbers. At the critical moment, Bai Sheng gave the government a clue because of greed, because he was discovered by others when he was taking the jewelry in Birthday. He was arrested by Jeju government and put into Jeju prison.
Bai Sheng is just a rascal, and his relationship with Classical is quite general, so when he was in prison, he gave up Classical directly in order not to suffer from the pain of flesh and blood. Thus, Bai Sheng's move is very un-heroic. Of course, this also paved the way for the classical Liangshan.
