Stocking up Hundreds of Billions of Goods, I Am Raising Cubs Scientifically in the Apocalypse

In the last life, Du Ruo was devoured by a scumbag mother and her son, and regretted not being able to see her daughter again. When she opened her eyes again, she was reborn and returned to the day before the end of the world, and was bound to the cub-raising system. "Materials are the guarantee for Zaizai's survival." Du Ruo stocked up like crazy. "A qualified mother needs to have strong strength to protect her cub." For the crystal core, Du Ruo picked up two big hammers and rushed into the zombies to kill them randomly. "Peer relationships have a profound impact on Zai Zai's emotional development." Du Ruo looked at his best friend who was showing off her food and thought deeply that it was time to find a partner for her best friend. "Zai Zai is about to give birth and needs an experienced doctor to deliver her." "Nanny, family doctor..." "Zai Zai needs to receive systematic education, educational institutions, teachers, classmates..." In order to realize the scientific policy of raising cubs stipulated by the system, Du Ruo rebuilt the post-apocalyptic world of the weak and the strong back into a civilized society.
