Mecha is the only answer for mankind.
Blue Star, the human home planet that was demoted and exiled. The old humans were genetically mediocre and were stepped into the dust by the new humans. They don't know that in the entire universe, only humans can build mechas.
Du Chen, the lowest level beast hunter in the wasteland, an orphan, codenamed "Zero". His only asset is his reaction speed - ten thousand times that of ordinary people. The bullets are moving slowly in his eyes, and the battlefield is full of flaws in his eyes. With a 100% synchronization rate and leapfrog driving, he started from the scrapped machine that was deceived, fought hard, and crushed it all the way.
The leader-level mecha "Earth Guard" recognizes him as the master, and the epic-level champion machine roars for him. While the top expert of the new human race was still proclaiming himself a genius for a thousand-fold reaction, he had already pushed the synchronization rate past the limit, allowing the legendary mechas sealed by the Federation to reopen their eyes.
No one knows that there is a bone of a mythical beast sealed in the center of the Blue Star Earth - the source of human genetic enhancement, a treasure that all races in the universe dream of grabbing.
The skeleton is in Blue Star, and the trump card is in the hands of the young man. The steel fleet took off, and the mechas chimed in unison: Notify the entire universe that Blue Star is online!
