Records of Retired Special Forces Soldiers' Extreme Apocalyptic Survival Notes

Dust covers the sky, and disaster is coming! High temperatures, cold waves, and mutant ferocious beasts take turns raging, the power grid collapses, food runs out, civilization is annihilated in ruins, and humanity is torn into pieces by hunger and fear. This is an extreme apocalypse where even survival is a luxury. Zhang Ergou, the former ace of the Longya Special Forces, once traveled to the battlefield of life and death, but after retiring, he was trapped in this hell on earth. There is no system, only the individual combat skills engraved in the bone marrow, the tried-and-tested tactical layout, and the wilderness survival rules engraved in the muscle memory. Living in an underground fortress, hoarding strategic supplies, relying on unity and rifles, and using a set of tactics to eliminate predators, he turned the bottom line of survival for special forces into the ceiling of survival in the apocalypse. But when the rescued survivor bites back, he sees clearly: the most terrifying thing in the end of the world is not natural disasters, but the unpredictability of people's hearts. The shocking conspiracy behind the disaster gradually surfaced. Should he guard the fortress and survive alone, or should he pick up a gun and fight for the innocent survivors to find a way out of the ruins?
