In the fourth year of the apocalypse, Lin Mo was handed over to the zombies by his mother and his uncle's family. Only as he lay dying did he see the truth: the jade pendant his father had left him was a pocket dimension, and he and his loyal dog, Black Wolf, had both become stepping stones for the others to survive.
When he opened his eyes again, he had returned to two weeks before the Red Mist Virus outbreak. A "Doomsday Survival System" had appeared in his mind, and the pendant he had reclaimed was clenched in his palm.
He had a contracted pocket dimension with a spirit spring, farmland where crops grew ten times faster, and unlimited storage. He used the startup funds from the System to stockpile supplies like crazy, renovated an abandoned air-raid shelter in the suburbs, and took back the despised Black Wolf, raising him on spirit spring water until he was as strong as a tiger.
On the day the virus struck, he coldly ignored his uncle's family's pleas and took Black Wolf to hide in an impregnable shelter.
After clearing out zombies, he awakened a lightning ability and rescued a doctor and discharged soldiers to form a team. From temporary safe zones to the Yingzui Valley base, he fought off zombie hordes, bitter cold, and acid rain, tore through marauders, and exposed corruption at the official base.
When his uncle's family joined an enemy base and came after him, he exposed their crimes from his previous life in front of everyone and left them to die amid the zombie horde. In the end, he joined forces with the righteous to form a human alliance and destroy the mysterious organization controlling the virus. In this life, he would protect his companions and make every traitor pay for their blood debts!
