Street Lights for All: My Resource Consumption Is Reduced by a Thousand Times

[National time travel + tower defense survival + system cool text + infrastructure farming] Humans aged 18-50 around the world were pulled into a world of eternal night overnight! Monsters are rampant at night, and you can only save your life within the range of street lights! Extinguish = completely disappear! At the beginning, each person only has a broken street lamp + 10 wood + 10 stone! Others used 10 stones to build a broken fence, which was not enough, so they shivered and waited for dawn. Ye Chen's awakening reduces consumption by a thousand times, 1 wood = 1000 wood! Buy 1,000 wooden arrows for 1 crystal and spawn monsters from a distance without any damage! 1 Crystal upgrades the street lamp, and the safety radius increases from 5 meters to 1000 meters! The local humans were collectively dumbfounded: How could this be a wilderness NPC? This is the coming of God! Global players collectively broke the defense: We play survival, you play infrastructure simulator? When the Lord of Darkness descends and billions of monsters sweep across the world, Ye Chen stands on the top of the eternal divine city: "From now on, the eternal night ends and light comes!"
