Qin Yu roughly described how she was kidnapped. However, she did not mention that she was poisoned and went through a life-and-death situation. It was merely mentioned in passing.
Although Qin Yu did not say it explicitly, the Four Little Ones were smart. They could guess that Qin Yu must have suffered a lot. She might even have been injured. Otherwise, Qin Yu would have contacted them much earlier.
Seeing their boss pretending to be calm because she didn't want them to worry, they felt both sad and touched.
[Boss, why did those people kidnap you?]
[It has something to do with my biological parents. Ning Chen is already investigating it. You don't have to worry about me. I will be more careful in the future.]
[Then... Boss, do you want us to arrange a few bodyguards for you? I think many from the Ning family are plotting against you. I am really worried] Ah Xi said in a worried tone.
