Xu Sanshi supported Bei Bei's choice, because he knew there was no point in stopping him. He was the same kind of person. If he were in Bei Bei's place, and Jiang Nannan were replaced by Tang Ya, he would have made the same choice.
Xiao Xiao and the others exchanged looks, but they still voiced their support. They also said that Bei Bei should bring Tang Ya back to Shrek City. With Tang Ya's cultivation, being out there alone without anyone to support her had to be difficult.
But Ji Lin knew that Bei Bei was destined to make the trip for nothing. Tang Ya had never intended to return alive this time—she had gone to seek revenge. Though Ji Lin did not understand Tang Ya's suicidal approach, he would not say much. He had never experienced the pain of having his parents die tragically and his sect's grounds forcibly seized, so he could not understand Tang Ya's feelings. Without experiencing it himself, he had no right to speak.
Although many things had already changed because of his arrival, he did not know whether Tang Ya's fate would be affected. Would Tang Ya still become an Evil Soul Master? When Tang Ya left, he had been in secluded cultivation at Sea God's Pavilion and had not had the chance to warn Bei Bei. Besides, he could not exactly tell Bei Bei outright, "Your Tang Ya has gone back to get revenge. She's gone to throw her life away, and she'll become an Evil Soul Master." Those words could not be spoken. Even Bei Bei, the person closest to Tang Ya, did not know what she truly thought deep down. How could Ji Lin possibly know?
Ji Lin was helpless as well. He had a good relationship with Bei Bei.
