Lin Changsheng transmigrates into the Primordial World and becomes the eldest disciple of the Jie Sect.
With the Calamity of the Investiture of the Gods approaching, the Jie Sect is doomed to see the Myriad Immortals Formation broken and its tradition wiped out. Lin Changsheng has the [Make-It-Up-and-Make-It-True System], but only the cultivation of an Earth Immortal. He's terrified and just wants to hide in some remote forest until the Journey to the West.
Then, just before Sect Master Tongtian leaves for a meeting at the Purple Cloud Palace, he puts Lin Changsheng in charge of the Jie Sect.
Faced with a bunch of hapless junior brothers and sisters destined for the Investiture of the Gods, Lin Changsheng only wants them to leave him alone so he can slack off. So he reluctantly starts spouting random ideas from web novels he read in his previous life:
Pointing at a kettle of boiling water, he teaches Zhao Gongming: "Take yourself as the seed, and condense 840 million divine elephant particles. This is the Divine Elephant Suppressing Prison Force."
Drawing a stick figure in the sand, he teaches the Three Maidens of Sanxiao: "At the end of the immortal path, who stands supreme? One glimpse of Wushi, and the Dao is emptiness! This is the Wushi Formation."
Watching sparks fly from the barbecue, he teaches Daoist Duobao: "Transform freely, transform the ages, transform time! This is the Art of His Transformation into Freedom."
He only means to bluff these fools into giving up and leaving him alone.
But... they actually believe every word, and through their deranged flights of imagination, they all master the techniques?
With a roar, Zhao Gongming unleashes the Divine Elephant Suppressing Prison Force and punches the Twelve Golden Immortals of Chan Sect to pieces!
The Three Maidens of Sanxiao lay down the Wushi Killing Formation, throw the ages into chaos, and even strip the three flowers from the head of the quasi-sage Randeng!
After Sect Master Tongtian nervously signs the Investiture of the Gods and prepares to return to Golden Turtle Island to lead his disciples in a last stand,
he looks at the Primordial Daluo Golden Immortals filling the island and Lin Changsheng casually grinding the Heavenly Dao beneath his feet, and is completely dumbfounded.
Tongtian: "Changsheng, I asked you to take charge of the Jie Sect. How did you turn them all into Great Dao Saints?"
Lin Changsheng is on the verge of tears: "Master, believe me. I really was just making it all up at first!"
