Ninju: The Protector of Yantai(The Second Multiverse)

Ninju: Shadow of the Dragon Mesh Yu Lingshan is the center of his parents' world—a heavy burden in the vertical monoliths of Yantai, where every citizen is a gear in a 30x scale industrial machine. At thirteen, Yu’s life is a rigid cycle of complex equations, school rankings, and the high expectations of a "model son." But when the sun sets behind the obsidian spires of the Yellow Sea, Yu bypasses the biometric locks of his family’s apartment to become Ninju. In a world thirty times larger than our own, the city is protected by the Dragon Mesh, a serpentine energy grid that weaves through the skyscrapers. While the legendary heroes of the West manage their own borders, Yu is the only one agile enough to slip through the Mesh’s blind spots and fast enough to stop the corporate saboteurs threatening Yantai’s infrastructure. Operating in a matte-black tactical weave—a high-performance suit that provides total identity shielding from neck to toe—Yu must balance his nocturnal hunt with the relentless pressure of a 9:00 PM curfew. But the Dragon Mesh is flickering. A new breed of infiltrator is hacking the city’s marrow, and they don't care that their opponent has a final exam at 8:00 AM. If Yu fails, Yantai falls. If he’s caught, he loses the only life he’s ever known. On a 30x Earth, the smallest shadow is the most dangerous.
