Library of Heaven's Path

After transmigrating into another world, Zhang Xuan unexpectedly finds himself in the esteemed role of a teacher. However, his arrival is accompanied by an extraordinary phenomenon: a mysterious library materializes within his mind. This mental archive possesses a remarkable ability—whenever he observes a person or an object, it automatically compiles a comprehensive book detailing their hidden flaws and weaknesses. Armed with this unparalleled advantage, Zhang Xuan swiftly transforms from an ordinary instructor into a truly formidable figure capable of seeing through any deception. With his newfound power, no one is safe from his piercing insight, regardless of their status. He casually confronts Emperor Zhuoyang about his baffling disdain for wearing undergarments, urging the ruler to maintain some semblance of dignity. He offers Fairy Linglong his unique expertise in lullabies whenever she suffers from sleepless nights, and boldly scolds the fearsome Demon Lord Qiankun over his overpowering garlic breath. Through these audacious interactions, Zhang Xuan reshapes the lives of those around him. Ultimately, this is an incredible tale of mentorship and growth, following an unconventional teacher as he grooms, guides, and shapes the most powerful experts in the world.
