"My dear mother, this is the formation newly developed by Hai'er, which can ensure the sect's safety." "Why do you call me my mother, sister?" "Sister, this is my newly developed formation." "Yuan'er, thank you for your hard work." Nonsense. Can this broken sect survive without me? "Report to the sect master, there is a Mahayana Venerable outside who is making noise." "Yuan'er, please leave quickly. I'll come to the rear." "You're here just in time, die for me!" "Huh?" "Sister, I mean, I have a way." After dealing with the Mahayana Venerable, Li Yuan complained in his heart that this generation of adults is really difficult to lead.
