Originally, Lu Xun intended to infiltrate the lowest level of the Underground City, quietly locate the main computer of 0c, and destroy it.
But he remembered something.
The strategic weapon that Jinghai City relies on for survival—the Emperor-Class Mecha "Giant Hero," is a colossal entity over three thousand meters tall and weighing over 26 billion tons.
To make such a large mecha overcome the flaw of being "clumsy" and become more agile than the pilot's own body, it naturally requires a super "brain" that matches the Emperor Mecha.
This brain is composed of three parts: Sea of Consciousness, Commander-in-Chief, AI Supercomputer.
Only through this trinity can the Strategic-Level Mecha unleash its true power.
This means that Jinghai City's artificial intelligence 0c is a part of the Emperor Mecha!
The Underground City has a total of three hundred levels, and from level -200 onwards, the next hundred levels are within the body of the "Giant Hero"... more precisely, its head.
