The current top ten mechas of China were all improved from black technology prototypes obtained from the Eternal Civilization.
During this process, Eldest Prince Li Tang of the Chuanke Civilization also played a crucial role, which is why he earned the title of "Father of Mecha."

Even those unstable models like the "Iron-Eating Beast," "Piyao," "Xiezhi," "Xingtian," and "Mo Ye" could rub their pride on the ground, in a direct confrontation, defeating five of them is not an exaggeration, it's almost modest to say so.
Russia's situation is special.
When Ma Ran, Su Qiangwei, Wu Di, Li Xing, and Zhang Kuang were on an expedition to the Eternal Civilization, a squad of alien invaders landed in Moscow.
These alien invaders seemed to have experienced a "car accident" upon landing in Moscow, as they all died violently and completely.
