Reborn as a Senior in High School, I Use the Way of Heaven to Suppress All Demons

I personally survived the end of the demonic disaster and died at the moment when the demonic tide broke through Qingnan City. I was reborn and returned to my senior year of martial arts high school three years before the catastrophe. I gained the ability to see through conspiracies and track evil spirits. Su Muyang wants to rely on extraterrestrial magic to gain power, the Soul Eclipse Society plans to lay a trap to destroy the city in the city, Black Wind Valley plans a large-scale invasion... I know all their plans in advance. Other people's senior year of high school was spent on completing exams and practicing to get a martial arts rating. My senior year of high school was about secretly laying out plans and clearing out hidden dangers. When the full moon rises in the sky and all the demons go to war, it will be my turn to use the heavenly runes in my hands to protect those around me and settle all old grudges.
