It's Intriguing: "Thirteen Eyed" immediately makes a reader stop and ask why. Since you have Noir plus his twelve clones all sharing a consciousness, it's a perfect literal and metaphorical description of his power.
It Fits the Genre: Long, descriptive titles are a staple of successful Cultivation and System novels (Manhwa/Light Novels). It tells the reader exactly what kind of epic scale to expect.
Here is the finalized description and tags with the new title integrated:
Legend of the Thirteen Eyed Cultivator
Description
He wasn't a hero, just a man with nothing left to lose.
In a dying Earth starved of resources, a scientist known as the "Dimension Breaker" promised a way out. Noir-a man without friends, connections, or anyone to miss him-was the perfect disposable test subject. Dragged into a desperate experiment, he was cast into a portal that shattered, dumping him into a world where the air is sweet but the gravity is a crushing five times that of Earth.
Haunted by the memory of his family's death and abandoned by his own kind, Noir refuses to be a sacrifice twice.
Applying a scientist's precision to the ancient arts of the Murim, Noir pioneers a cultivation method the world has never seen. Instead of a single Dantian, he maps his entire anatomy, forging micro-Qi cores in every joint, fingertip, and toe, and anchoring them in the centers of his palms and feet. This intricate network of stabilized energy transforms his body into a living machine of absolute efficiency.
To master the world's secrets, he creates twelve clones, sending them to infiltrate the most elite sects-from the venomous Tang Clan to the lightning-fast Spear Masters. Together with his clones, he sees everything. With thirteen sets of eyes and his shadow-shikigami Huanli by his side, the man who was meant to be a footnote in history is now the legend rewriting the laws of immortality.
