On the day I completed the mission, Song Beichen lost a life saving me. I begged the System to exchange my reward for bringing him 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 him talking with his first love. I gave a bitter smile. Reviving someone costs four lives. Even if he got the System, he wouldn't have a life left to use it...
