Shu Yu has passed through the book, and has become a poor cannon fodder who was implicated by the dead female supporting role and only appeared twice and was finally exiled for thousands of miles.

After finding that he could not change the result, Shu Yu decided to eat, drink, lie down and wait.

Who knew that the exile had not yet come, but she was suddenly told that she was not the daughter of the Shu family.

And the Shu family decided to obliterate her in order to hide her blemish.
