Organic Armor's Ultimatum

In the cosmic century, humans in the solar system are exploring the unknown in the vast space. The United Blazing Steel immigration organization developed on a habitable planet similar to its hometown and named it Robug. During the construction of the settlement, people accidentally discovered the corpses of creatures buried underground. Through analysis, they learned that they were organic weapons that had existed for a long time. The curse began when scientists tried to apply the technology of organic weapons to humans. Organic weapons began to attack from fixed directions, causing disasters in settlements and killing more than 300,000 people. Scientists named this terrifying organic weapon the "physical shape of killing," or killing shape for short. In the 190th year of the star calendar, the Blazing Steel United Regiment formed an army of 100,000 people, capable of fighting like organic weapons, named the Blazing Steel Adjudication Army. Starting from the settlement, march along the Xingxing attack path to eliminate all threats. The last time the Blazing Steel United Regiment received contact from the Judgment Army was two hundred years ago. After that, there was no more news, and the Killing Form never appeared again. People gradually forgot about this army and moved on with their lives. In the year 226 of the star calendar, Ji Wangguang, the only survivor of the Judgment Army, returned to his former hometown and found that everything had changed.
