Death Work Order: Please Sign

A 'Death Work Order' falls from the sky: whoever signs it, goes to the bureau. Former board game designer Shen Ye uses his rule-designing mind to dismantle rules, while former criminal profiler Lin Wan uses her mind-reading eyes to watch people. One dismantles, one observes, and the two join forces to turn every delivery of the death courier into a high-IQ counter-kill. Until the host 'Old K' reveals his true face—this game was, from the very beginning, a final game tailored for Shen Ye. — Description from novelcodex.org
