On the day I completed the mission, Xia An'an lost a life saving me. I begged the System to exchange my reward for bringing her back to life, while I stayed in this world and endured the price of reviving someone day after day. After three years of unending pain, I accidentally overheard her talking with her first love. I gave a bitter smile. Reviving someone costs four lives. Even if she got the System, she wouldn't have a life left to use it...
