May I hug you?” Watching the woman slowly fade away, Shangguan couldn’t bear to refuse. “I can take you out of here.” “No need.” The woman in white shook her head and gazed into the distance, toward the place where the sun rose. “I still have to keep Li Meng company. She’s so afraid of the dark.” But the sun would never rise again. … Shangguan Xuan slowly came to, pressing a hand to her still-aching chest as she stared in confusion at the shattered security guard before her. She smiled, bright and dazzling like the sun high above. “I killed you to survive. I saved you for the sake of all living things.” As soon as the security guard finished speaking, he turned into countless fragments and vanished from this world. Shangguan Xuan watched the scene in silence and murmured to herself, “I think I’ve forgotten something.” … Eerpis led Shangguan Xuan to a tombstone and told her about the person buried there, the only casualty of the Ning’an Campaign. “Xiao Xuan, what kind of person do you think this was?” “Righteous and noble, facing death without fear, unafraid to make the ultimate sacrifice…” Eerpis fell silent for a moment, then looked toward the horizon and said calmly, “He was a corrupt official, a coward who was afraid to die.” … “Xiao Xuan, do you remember? I taught you this, you know~” “Xiao Xuan, do you remember? I taught you. Come on, stand up! Then… kill me.”
