I Was Just Slacking Off and Taking on a Disciple, So How Did They All Become Immortal Emperors?

Years ago, after his master died, Chen Yang unexpectedly became one of the seven peak lords of Tianyuan Sect. He had hoped to make his peak flourish, but his talent was mediocre. Not only did his disciples betray him, but his fellow sect members mocked him as well... "Am I doomed to achieve nothing in this life?" [Ding! The Do-Nothing Celestial Master System has activated. As long as you refuse to compete and overwork yourself as a master, your disciples will receive ten thousand times the benefits!] [Let your disciple waste half a day of cultivation, and receive a ninth-grade Marrow-Cleansing Pill!] [Spend three days slacking off at the foot of the mountain, and receive an immortal-grade cultivation manual!] "Eat up, my good disciple. Your master risked his life to get you this immortal pill!" "Take this. Your master just forged this immortal-grade treasure." His disciples bowed to him again and again! "Master! Stop fishing already. We're sick of eating the dragon carp from the mountain stream!" "Master! If you keep slacking off, your disciples are going to become immortals!"
