Lin Zhao, who was originally an ordinary survivor who died of radiation sickness in the third year of the apocalypse, was reborn and returned to 72 hours before the apocalypse broke out. He is bound to the "Ark System" with him, which can scan warehouse locations around the world, automatically hoard supplies, and upgrade survival technology, but each use requires "hope points" - converted from the trust or gratitude of others.
Lin Zhao must hoard enough supplies and establish a safe stronghold within 72 hours to meet the upcoming "big collapse". However, he discovered that three other reborn people were also acting secretly, and one of them actually had a system similar to his, aiming directly at the ultimate control of the "Ark Warehouse".
Purpose: Survive
