Doomsday Roulette: End of Seven Days

There is a cycle of seven days, and there is no end to the end. When Lin Mo woke up in a strange space, his memory was cleared and he was only given a set of No. 127 Clothes and a "survival system" that was delayed, stuck, and had incomplete information. What he has to do is to sign in and survive in seven completely different hells (data collapse, spiritual erosion recovery, aberration beast tide...) And collect fragments. The system told him that as long as he killed the final "Lord of Reincarnation", everything would end. But he never expected that the Lord of Reincarnation would be... When the end comes and the order collapses, should we go with the flow and release our animal nature, or should we stick to the glimmer of humanity? Is the end of the seven-day cycle the end, or is it another beginning?
