[Spirit cage fan + apocalyptic guardian + group portrait of strong women + time travel and salvation + ability fusion + warm epic]
A barrage of grievances for Wulan Maiduo unexpectedly involved three modern women with incredible abilities - Liu Ruyan who summons a tide of beasts, Hua Ruhai who controls the undead, and Yue Ruge who created a mechanical empire - into the apocalyptic wasteland of "Spirit Cage". Their first encounter was a life-and-death situation. They used their special powers to save the dying "Little Sun in Red", and from then on they made a vow to "protect you throughout your life and change your destiny." From the roots of the bond in Dragon Bone Village, to the game against the old order of the lighthouse, to understanding the truth about Mana's ecology, and reconstructing the world with "healing" instead of "destruction" - this is not only an epic in which the three empresses use the power of summons, undead, and machinery to overturn the rules of the apocalypse, but also a tender journey in which the "sisters" protect Mado's smile and accompany her to grow from an outstanding warrior to a leader in the new era. When the tide of beasts, undead and steel torrents intertwine, and when personal protection sublimates into the salvation of civilization, they will eventually light up a never-extinguished light of hope for Mai Duo and the survivors on the broken earth.
