Return to Zero Date

One day, many asteroid gravels gathered on the Stowe continent. People discovered that this gravel was an excellent industrial mineral. This mineral allowed humans to break through the technical bottleneck, so they continued to mine it. This mineral continued to increase until one day, a miner got a strange disease, which people called For the "Return to Zero Disease", it was finally discovered that a key component of the treatment drug still requires the use of ore, but the distribution is extremely uneven, and the purity distribution is also extremely uneven. In order to fight for it, people launched wars. International forces collapsed, order collapsed, cities turned into ruins, and humankind's once glorious civilization no longer existed.
