Okay, I see where the confusion comes from because the name can get mixed up with some other works. 'Peerless' is a wuxia novel by Meng Xi Shi, following Gu Yun and Chang Geng. The main thread is actually a slow-burn romance wrapped in a political intrigue and war setting, not a typical cultivation story about becoming the strongest.
Gu Yun is the Marquis of Order, a seemingly carefree military commander who's nearly deaf and blind from old battlefield injuries. Chang Geng is his godson, a young man with a hidden, traumatic past and a volatile temperament. The plot really kicks off as Chang Geng grows up and his true, politically explosive heritage is revealed, forcing Gu Yun to navigate protecting him while managing threats from foreign tribes and a corrupt court.
A lot of the tension comes from their dynamic—Gu Yun trying to shield Chang Geng while underestimating how much Chang Geng has grown into a formidable, cunning force himself. The steampunk-lite elements with the 'Ling Shu' mechanical arts are cool, but they're background for the character drama. The central question is whether their bond can survive the secrets and the immense pressure placed on them.
I kept reading more for their conversations and the way Chang Geng's devotion borders on obsession than for the battle scenes.
