Black metal monoliths, resembling tombstones, even with a thickness exceeding one meter and a height of over thirty meters, cannot block five Prince Mechas. Yet their purpose isn't to block mechas but to buy time for the 'Nameless faction.'
Despite reaching the Alien Planet and undergoing training for a while, the Nameless faction doesn't possess the combat power of an Independent Group. Even the weakest of the five Independent Groups, the Azure Independent Regiment, could annihilate the Nameless faction given both are piloting mechas of the same level, with casualties not exceeding one-third.
This demonstrates the significant disparity between repeated training and actual combat, much like the Empire Royal Mecha Guards' Duke Mechas. Even though each Ape Mecha warrior has been meticulously selected and granted Third Stage Realm's gifts, they couldn't wield the absolute advantage of 300 Duke Mechas, leading to their defeat by Ji Xinghe's command.
