An ordinary girl, Lin Xiaomao, accidentally awakens her talent of Holy Light. In order to protect her family, she gets involved in three secret realm trials left over from ancient times.
The underground caves imprison the trapped consciousness projections, the illusion of the heart mirror will amplify the obsessions and regrets deep in the human heart, and the ancient tombs and cities bury the true source of the catastrophe.
The danger is not only the deformed creatures from other worlds, but also the inner demons that are difficult for people to escape.
She encounters Lou Xiao, who also carries the past, and the two go together to pass through the levels of locking the soul, locking the heart, and locking the roots.
The disasters in the world are not caused by demons, but caused by the imbalance of ancient protective formations over time.
They don't need to kill everything, they just want to repair the broken formation, destroy their self-obsession, and replace the world with eternal peace.
Purpose: People in difficult situations must learn to reconcile with their past. True protection is not only about fighting against external suffering, but also about accepting the fragility of the heart and making it clear inside and outside. Only then can we protect the ones we love and seek long-term peace.
