Found an Error
Originally, it was said that the protagonist was an earl, and should be Uncle Tianying instead of Marquis Tianying, but I wrote the wrong chapter name and there was nothing I could do to change it.
I might as well write some more reasonable plots in the previous chapter, and the title of Marquis Tianying will be no problem. Book friends who have already read it and feel something is wrong can download it and read it again.
