Rong Gu, a senior special operations leader, accidentally fell into a different world where mechas and extraordinary rules coexisted. He made no high-profile declarations and only relied on his past special operations skills to act cautiously. However, he was successively imagined by various local forces to become a hidden mecha boss. He steadily unlocked the mechas of the past generations according to the settings imagined by all parties, and finally relied on the advantages of Dihua and the combat power of the mechas to sweep across the continent's disputes, gain a firm foothold and open up a unique survival territory.
