Lin Wan understood everything from the moment she saw Ling Xiao.
At that time, the master rescued himself from the mouth of a monster and changed his face beyond recognition, and used immortal magic to reshape his appearance.
Just pretend that the Immortal Lord has never seen his original self, so the image he created is not even remotely similar to himself.
Now facing a face that was so similar to Ling Xiao, Lin Wan knew that for so many years, she was just a substitute for a person who had "passed away".
And now the substitute is back.
Everyone in the sect, including Master and him. . . All these years I have just seen Ling Xiao through this face.
I think that when Master asked her her name, she only said: "Lin..." And then lost consciousness. . I think it was because of this word Lin that he saved his life.
