High Temperature Apocalypse: I Have a Storage Ring

When Lu Chen breathed his last in the 80°C ruins, he saw clearly: the mineral water handed over by his girlfriend was laced with poison, and the adulterer's knife was pointed at the storage ring in his hand. The ring that accompanied him through the three years of the apocalypse became his talisman. He woke up suddenly, the air conditioner was bitingly cold - he returned to seven days before the end of the world, the ring was still there, and the enemy was not far away. Selling a house and taking out a loan, he stocked up like crazy: enough water for three years, enough grain to last four seasons, and medicines to fill five medical boxes. He looked for guns on the black market and bought enough pistols and bullets, and hid his modified AK47. The scorching sun is coming, and purgatory will restart. In this life, he is no longer a "good guy" who can be slaughtered by others, but an avenger with rings and weapons in hand - survival is only the first step.
