[Rebirth in the Apocalypse] + [High Temperature Natural Disaster] + [Underground Fortress] + [Farming Survival]
Forty days before the cataclysm when he was reborn in the sun, Lu Ran awakened his sense of earth veins.
In his last life, he was killed by his "companion" while being burned at 80°C over a bottle of water.
In this life, when everyone was frantically buying air conditioners, he quietly bought up the top insulation materials in the building materials city, hired a drilling team to directly explore the deep underground water layer, and built a constant-temperature ecological fortress fifty meters deep.
A heat wave descends and the ground turns into a furnace. Instead, he grew crops, recycled water, and even had a cryogenic swimming pool in his safe house.
Until one day, the sound of drilling came from overhead, and a hoarse threat sounded: "Hand over the refrigeration technology, or we will turn your 'refrigerator' into an oven."
Lu Ran looked at the entire underground kingdom under his control and smiled.
