Just as he’s about to take his life, a small girl’s ball rolls into the street, with a speeding truck barreling towards her. In a moment of selflessness, Nagi rushes out and saves the girl, sacrificing himself in the process. Fatally injured, he reflects on the idea that it's better to die doing good than bad.Nagi awakens in a surreal, white world, where he is greeted by an angelic figure who offers him two choices: remain in eternal peace, free from suffering, or be reborn in a different world where he could seek redemption and a second chance at life. Nagi faces a life-altering decision—rest forever or attempt to find meaning and fulfillment in another world.

For example, the hidden passages in their room, the poisonous carp in the pond, and the countless hidden weapons on her person…****Later.Two groups of men in black arrived outside the thatched hut in the suburbs of the capital.Commander Yan, observing the group trying to capture the Loucha Sect leader’s weakness, pondered for a moment, then put away her hidden blade.-Maintain a gentle and virtuous demeanor.Sect Leader Yu, watching the group attempting to seize the Jinyiwei commander’s weakness, fell silent for a moment, clutching his chest and coughing.-Appear frail and refined.
