The Nine Guardians of the Upright Martial Arts Alliance were framed and put to death, but when they woke up they found that they had been packed up and sent to the Demon Sect. The villain, the deputy leader of the Demon Cult and the future successor of the Demon Cult, admires the Nine Guardians quite a lot and has helped him many times. Who says there is no coexistence between good and evil? Maybe the two of them have met before?
Purpose: Anyone who commits unjust acts will be punished by his own death.
