Master-Disciple System: Summon Xu Fengnian from the Start

Other people pour their hearts into recruiting disciples. I recruit mine by signing contracts. Xu Fengnian is my first disciple, Ye Fan calls me Master, and Xiao Yan has to call me Sect Master. The extraterrestrial demons are invading? No problem, I'll call in reinforcements.

Lin Yun was the strongest special forces soldier in Huaxia in his previous life. He died protecting his teammates during a top-secret mission, then unexpectedly crossed over in spirit to a world of cultivation, where he became Lin Yun, the young sect master of the declining Qing Shan Sect in the Northern Region. As soon as he wakes up, he faces the sect's imminent destruction: two third-rate sects have joined forces and are at the gates, his father is gravely wounded, the elders have fallen, and the disciples have suffered heavy casualties. The original Lin Yun went out to seek help but was ambushed. At death's door, he activates the Master-Disciple System and summons his first disciple at random: Xu Fengnian, whose cultivation is at the peak of the Nascent Soul stage!
