Doomsday struck suddenly, a cave saved my life. I live secluded in mountains with ample supplies.

The male protagonist originally planned a simple and relaxing mountain fishing trip to escape the hustle of urban life and soothe his daily fatigue. He packed light fishing gear and basic necessities, looking forward to peaceful leisure time in the quiet mountain waters. However, the brutal doomsday descended abruptly and without any warning, shattering all ordinary tranquility in an instant. Unexpected disasters swept across the entire region overnight, throwing the bustling city into chaos and eliminating all safe living conditions for ordinary people. Caught completely off guard with no chance for full pre-disaster preparation, he made a prompt and decisive choice to save his own life. Abandoning the chaotic and dangerous urban area, he fled alone to the remote mountainous wilderness far from human turmoil. After trekking through rugged mountain roads, he discovered a secluded hidden cave with superior terrain, perfect for sheltering from external disasters and threats. Carrying only two months of portable survival supplies he brought for his fishing trip, he officially settled down in the desolate wilderness and started his solitary doomsday survival life. To sustain long-term survival, he stuck to a regular daily routine. He headed to nearby mountain waters to fish every day, drying excess catch into durable dried fish to build up stable food reserves. He carefully renovated and reinforced his cave dwelling, blocking cold wind and rain leakage to create a safe living space. Meanwhile, he remained highly vigilant at all times, taking strict precautions against rampant snakes, insects and ferocious wild beasts that roamed the mountain forests, warding off potential wilderness dangers. Peace never truly lasted in the apocalyptic mountains. Faint yet clear gunfire often echoed through the mountain valleys, hinting at unseen human conflicts and hidden perils lurking in the wilderness. During one of his return trips to the cave after restocking necessities, he even encountered a deadly venomous snake, forcing him to fight cautiously to survive. Amid the turbulent situation, he also spent gentle and warm moments with familiar old acquaintances. Beneath these seemingly stable and peaceful survival days lay countless dormant crises and unknown risks. This is the ordinary yet tough journey of a common angler, who guards his life carefully and survives steadily in the cruel and unpredictable post-apocalyptic wilderness.
