Stocking up on Goods Due to Natural Disasters, I Am Free and Happy in the Apocalypse

The end of the world is coming, natural disasters are rampant, extreme heat, extreme cold, hurricanes, tsunamis, floods, earthquakes, raging viruses, animal mutations, eternal day and night take turns. In her previous life, Lu Zhixuan walked alone in the apocalypse and survived for five years. In the end, she was betrayed by the child she rescued and raised, and eventually died together with everyone in the laboratory. When she opened her eyes again, she went back to the year before the end of the world. In this life, she wanted to kill scum and protect her relatives. The most important thing is to turn on Nuanyuli's space cheating artifact and start stocking up mode. But I don't know why she has returned from the apocalypse. Why are Lu Yi and Jian Zhu more interested in hoarding goods than she is? Airplane? Tank? There are actually warships. Forgive her for not having seen the world. Lu Yi comes from a military family and holds the rank of major. When the apocalypse came, he originally wanted to avenge his family's Jiaojiao for the past life and then retreat into seclusion early. However, he unexpectedly discovered the truth that had been hidden for many years. Those families that had been hidden from the world swarmed in like wild beasts under the sea. He and Yinyin were destined not to be able to stand idly by in this apocalypse. Their birth had destined them to be involved in these right and wrongs.
