Traversing into another world, Zhang Xuan finds himself becoming an honorable teacher. 
Along with his transcension, a mysterious library appears in his mind. 
As long as it is something he has seen, regardless of whether it is a human or an object, a book on its weaknesses will be automatically compiled in the library. 
Thus, he becomes formidable. 
"Monarch Zhuoyang, why do you detest wearing your underwear so much? As an emperor, can't you pay a little more attention to your image?"  
"Fairy Linglong, you can always look for me if you find yourself unable to sleep at night. I am skilled in lullabies!" 
"And you, Demon Monarch Qiankun! Can you cut down on the garlic? Are you trying to kill me with that stench?" 
This is an incredible story about teachers and students, grooming and guiding the greatest experts in the world!

"An opportunity to comprehend the fifth realm?" Zhang Xuan was slightly taken aback.

"Indeed. The fifth realm of the Eye of Insight is known as Phantasmagoric Construct. An illusory world created through the eye, this technique allows one to plunge even experts surpassing Saint 9-dan into living hell, a nightmare that they will never awake from. Back then, with this very technique, my teacher, Ancient Sage Bo Shang, eradicated over a million Otherworldly Demons with just a single glance, creating an undefeatable legend!

"Under normal circumstances, it's impossible for one to comprehend this realm without being in the Ninth Netherworld Dimension, but in view of the fact that you are leaving in order to save your student, I'll make an exception just for you. As long as you can comprehend the fourth realm, Demon Vanquisher, and decipher the final seal on the Sanctum Head Token, I'll grant you an opportunity to comprehend the fifth realm," Sage Kui said.
