This point coincided with the Emperor's intentions. When he first met Lian Bingcai, he thought him timid and pathetic, like a lump of mud that couldn't be helped up against a wall. Wanting to give this man something to do to prevent him from causing trouble outside, it was just right that this man wanted to learn the skills of the Shadow Guard, so he was thrown into the Shadow Guard Camp.
Like the time someone had grabbed Lian Bingcai before, fortunately, Lian Bingcheng was guarding against it and didn't mention anything about Lian Hua; otherwise, Lian Bingcai would surely have sold out his Little Concubine completely, and it would have been difficult to manage things afterward.
