Si Lingtian must confirm the condition of his great-grandson every day, as well as Si Yuhao's condition, before he can feel sleepy.
If either of them has a problem, Si Lingtian won't be able to sleep all night.
Today's news is still good news; however, for Si Lingtian, he has to face Si Yuchen's interrogation sooner or later. Si Yuchen probably hates him deeply now, and as soon as he seizes the opportunity to find the child's hiding place, Si Yuchen will immediately escape from Si Lingtian's grasp.
Si Lingtian can see through Si Yuchen's recent actions right away, but they are both his beloved grandsons, so he cannot favor one over the other.
Therefore, even though Si Lingtian doesn't want Si Yuchen to continue investigating, the child is very safe with him, and he wouldn't harm him.
But Si Lingtian still wants to understand Si Yuchen's anxious and worried feelings; the child is still young, so it's only natural for him to be concerned.
