Eighteen-year-old death row inmate Ye Lin is conscripted by a special investigation unit before his execution, drawing him into the global "Death Reincarnation" vortex. Every death exam forces examinees to find the only way to survive within a limited desperate situation through bizarre rules. Facing alien species, zombie tides, and human calculations, Ye Lin repeatedly breaks through death deadlocks with astonishing observation and near-cold deduction, and walks side by side with the hidden-identity An Ke from mutual testing. But when their accumulated points are enough to exchange for power or even leave the reincarnation, they discover that the so-called exam is merely a screening, and the secrets of missing persons, mysterious organizations, and "gods" point toward an even greater disaster.
