Lu Jin was bound to the "Apocalypse Breaking System" during the zombie siege, and he entered the apocalypse at the beginning of the nuclear pollution - the system analyzed that "mutated cockroaches are afraid of high temperatures", so he burned a wall of flames to fight back; in the apocalypse of ice, he exchanged for "constant temperature protective clothing" + "geothermal generator" to transform the survivor camp into a safe area; in the apocalypse of floods, he relied on "underwater breathing medicine" + "giant assault boat" to uncover the black-hearted leader who was hoarding supplies. There are 400 planes, with zombies, mutated beasts, and extreme weather taking turns to fight. Lu Jin uses the system to fight through all desperate situations, from being a lone survivor to becoming the "patron saint of mankind" in every apocalyptic plane, while also cultivating the system to be able to criticize and complain about others.
