Si Lingtian asked Mu Shan to return to Sea City because Mu Shan could handle Si Yuchen.
No matter what Mu Shan's feelings toward Si Yuchen are, or what Si Yuchen plans to do with Mu Shan, it is undeniable: Mu Shan's words are much more effective than those of this old man.
Moreover, Mu Shan directly benefited from Si Yuhao's surgery. Without him, Si Yuhao wouldn't have escaped danger, let alone woken up.
Mu Shan should be grateful to him, and he is willing to accept Mu Shan back into the Si Family.
Logically speaking, since Mu Shan was driven away by him, Si Lingtian would not accept her back as his granddaughter-in-law.
It was Mu Shan's instigation, otherwise, Si Yuhao wouldn't have gone to dangerous places for investigation.
The reason the Si Family is so fractured now cannot be separated from Mu Shan's involvement.
What exactly Mu Shan did in all this, Si Lingtian doesn't want to pursue any further.
