The Seven Greatest Heroes

After complaining about a book on cultivation, Jiang Yuting became an unknown cannon fodder in the book. Endless work, sour steamed buns, starting in hell mode, luckily I picked up a tsundere elf king as a plug-in, awakened the ultimate ice spirit root and went all the way. I chose the most remote academy for Lying Down, but gathered a lot of ruthless people including the male protagonist of the original novel, the young master of the Spirit King, and the auxiliary boss. As the countdown to the truce between humans and demons begins, the secret of the black mark on her forehead comes to light. It turns out that her existence is the biggest bug in the original work!
