The debts accumulated a hundred years ago are reincarnated into this life. One wrong step, every wrong step. The birth of the alien species, the arrival of the Blood Walker, the recasting of the red crystal, the struggle of the true body... Step by step, the red crystal girl Jiang Xuling fought bloody battles for the faith in her heart. Who says the world has no room for aliens? Who says walking alone is weird? We long for an inclusive space, and we are obsessed with a reason for existence. If you love, love, hate, hate, hold on to what you want, and never let go if you love deeply. A boy who awakens in a utopian family, and a girl who fights against everyone's strange eyes. They know each other, love each other, and kill each other. Regret, pain, chagrin, unwillingness, emotion, happiness... When all mistakes are forgiven, when all obsessions are let go, when all prejudices are offset, everyone will usher in their own independent planet, and mankind will usher in a new era.
