[Natural disaster + stocking up + abilities + team formation + space] Extreme heat, extreme drought, extreme night, and extreme cold. The earth seems to have pressed the reset button to eliminate all viruses called "human beings"! After struggling for ten years in the cruel apocalypse, Lin Youyou finally died tragically at the hands of a trusted companion. After rebirth, she went back to five years before the end of the world. She originally thought everything was a dream, but the space earrings she brought back with her memories reminded her all the time that everything was really happening! In five years, she must stock up on supplies, learn skills, and be fully prepared, and she must seize the opportunity and kill the enemy with her own hands! "I will repay those who help me! I will kill those who harm me!" Just when she was making all preparations to welcome the end of the world, a shocking news disrupted all her plans! It turns out that she is not the only one in this world who has been reborn! Lightning rod: 1. There is a male protagonist, but there are not many emotional lines. Let's stop guessing about the male protagonist! 2. It's not a happy novel in the traditional sense, but it's definitely not sadistic or frustrating! 3. The heroine is kind, but she is not a white lotus; she is ruthless, but she does not destroy her outlook on life. There is her persistence, but also her little personality and shortcomings!
