In the End of the Xuan Dynasty, I Have Stocked up Hundreds of Millions of Supplies to Come!

[Hoarding supplies + technology and hard work + dimensionality reduction attack + time travel + zombie apocalypse + farming + developing forces + microsystem] Qin Kong, who was surrounded by a wave of corpses, relied on the divine jade at the last moment of being bitten to return to the modern society before time travel. When he learned that he would travel again to the end of the Xuan Dynasty three months later, Qin Kong relied on the space of the ancient divine jade to start hoarding goods... In the last reincarnation, the zombies showed me what real fear is, and the pig teammates before the zombie wave showed me what it means to be dangerous... In this reincarnation, I want to let the zombies and those who look down on me know what technology and ruthless work are! ! ! "Is there a shortage of food? Don't be afraid, I can't finish all the compressed biscuits in my space!" "The city wall collapsed?? Don't worry, watch my quick-drying cement come on stage!" "Insufficient firepower?? Come here!! Pull out my 152mm howitzer!!" Qin Kong, who once again traveled back to the mysterious dynasty of the last days, relied on technology and hard work to vow to change his destiny. "I will definitely hold my destiny tightly in my hands in this reincarnation!" "I want to build the strongest stronghold city in this troubled world, and then live a stable, prosperous and complete life with my most important people!!" "Inventing history and changing the world with magic, I hope everyone enjoys watching it"
