Ice Age: My Mobile City Evolves Infinitely

[Farming] + [Technology Tree Upgrade and Evolution] + [Mobile City] + [Wasteland] + [Refreshing Read] + [City Warfare]An ice age has arrived, and global temperatures have plummeted to minus sixty degrees Celsius. Amidst the swirling snow and ice, only mobile cities powered by geothermal cores and heavy machinery serve as humanity's last refuge.Lu Chen, who transmigrated to this cruel world, started by inheriting only a "miniature tracked snow fortress" that was on the verge of falling apart. The city's population was 1, and the available fuel could last for 3 days.Fortunately, the [Truth Technology Tree System] has awakened!By collecting resources, you can unlock four major branches: [Power Engine], [Infrastructure Armor], [Ecological Logistics], and [Armored Weapons]!"Ding! Activate the [Eco-Logistics - Soilless Cultivation Trough] and enjoy fresh cabbage at minus 80 degrees Celsius!""Ding! [Power Engine - High-Pressure Polymerized Steam Core] activated, the dilapidated vehicle transforms into a heavy-duty ice-breaking fortress!"While other large city-states fought tooth and nail for a piece of inferior coal, even pushing civilians into icy abysses, inside the sinking, mobile city, people were enjoying constant warmth, eating hot pot, and admiring the ice sculptures outside through bulletproof glass.The rival city lord was devastated: "My massive armored city can't even ram his icebreaker? Where did he get those terrifying train cannons?!"Lu Chen smiled slightly: "Infrastructure? Just max out the technology tree, right? I'll never skip levels. I'm all about stability."
