How Could All the Rebel Disciples Become Great Emperors by Making up the Exercises?

Chen Changan traveled through the world of immortality for three hundred years. He had no cultivation and relied on pretending to be an ancestor. Seeing that his yandere disciple was about to force a bridal chamber, in order to escape, he casually made up a ridiculous set of exercises such as "stepping on the right foot with the left foot and turning the true energy into old duck soup". Unexpectedly, the disciple had an epiphany on the spot, and stabbed the great master of the transformation stage who came to collect debts into the mountain with one finger! The system is activated, and the apprentice has mastered the made-up technique, which will feed back his cultivation a hundredfold and last for thousands of years! From then on, Chen Changan was on the road of making things up, never to return. He made up "lawn mower with dog's tail grass" for the second disciple of Jiuyin Juemai, and fed back the sword meaning of Dzogchen, the grass character, and smashed the ancient cave of the devil with one sword! Make up "radio gymnastics" for a beggar with a broken arm, feed the ancient holy body in return, and punch the heavenly being in the immortal world! As his disciples became more and more outrageous, Chen Changan's cultivation level was completely out of control. When the Immortal Emperor of the Upper Realm tore through the void and led millions of immortal soldiers to the mortal world in an attempt to obliterate this anomaly, Chen Changan sighed helplessly and threw out a piece of dogtail grass. In an instant, the galaxy broke, the avenue collapsed, and the aloof Immortal Emperor was nailed to the Nantian Gate by a weed. All the worlds went completely crazy: "You call this a useless ancestor? Every sweeper under his sect can tear apart the Heavenly Dao with his bare hands!" Chen Changan looked at the Empress of All Worlds who was rushing around the courtyard to warm his bed, and fell into deep thought: I really just made it up casually!
