Excuse me, what happened to the assassin doll in Princess Zhu Huan II? Who is the assassin? Is it that high? Why did the assassin never come back after he entered Shufangzhai?

The assassin doll in the second part of Princess Pearl is a plot designed by the Queen to frame Swallow and Wei Zi. The queen found an assassin named Balang, and let him enter Shufangzhai to assassinate the emperor, and then left the doll in Shufangzhai as evidence of the crimes committed by Swallow and Wei Zi.

As for who the assassin is, the TV series is not clear. However, as can be seen from the plot, the assassin belongs to the queen, and Balang is just a tool to be used.

As for why the assassin didn't come out after entering Fang Shu Zhai, it may be because he has finished the assassination task, or it may be because Fang Shuzhai's people found him and caught him. In the play, after Swallow and Wei Zi were taken back to the palace, they found Balang who was hiding in Zhai, Fang Shu, which also confirmed that the assassin had been arrested.
