Master-Apprentice System: Summon Xu Fengnian at the Beginning

Others accept apprentices with all their heart and soul, but I only rely on signings to accept apprentices. Xu Fengnian is my eldest disciple, Ye Fan calls me master, and Xiao Yan calls me sect leader. An invasion by extraterrestrial demons? It's okay, I'll shake people. Lin Yun, who was the strongest special forces king in China in his previous life, sacrificed his life to protect his teammates while performing a top-secret mission. His soul accidentally traveled through the world of cultivation and became Lin Yun, the young master of the Qingshan Sect, the last sect in the Northern Territory. As soon as he woke up, he faced the desperate situation of the sect's destruction - the coalition forces of two major and third-rate sects pressed on, his father was seriously injured, the elders died, and his disciples suffered heavy casualties. The original owner went out to ask for help but was plotted against him. When he was about to die, he activated the "Master-Disciple System" and randomly summoned his eldest disciple at the beginning: Xu Fengnian, the perfect Nascent Soul!
