Time travel background: Four girls in dormitory 403 of a modern university were playing a retro zombie game together on a thunderstorm night when they were struck by a strange lightning and traveled together.
· Time-travel identity: Become four apprentices with different personalities and talents (the original names or homophonic names can be used) under the zombie Taoist priest Chizuru.
· Core system: Each of the four awakens the four-spirit inheritance system, but the initial abilities are sealed and need to be unlocked through experience.
· Qinglong (Wood·Vitality): Mainly used for healing, purification, and exorcism. In the later stage, the Qinglong Dharma can be summoned.
· Suzaku (Fire·Destruction): Main attack, talisman, and flame. In the later stage, Nanming Lihuo can be controlled.
· White Tiger (Gold·Qingsha): Mainly used for melee combat, weapons, and killing. In the later stage, it can transform into the White Tiger's aura.
· Xuanwu (Water·Guardian): Main defense, formation, Xuanbing, and can set up absolute defense in the later stage.
· Initial limitations: System capabilities are linked to one's own Taoist cultivation and cannot be achieved overnight. It takes time to fuse the memories of the four people, and "modern jokes" often pop up to confuse Master Chizuru, creating interesting contrasts.
