Heng Sao Tian Ya

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!

"Make a bet with me, and we shall see," Zhang Xuan said. "Well, even if you refuse my bet and take me away forcefully, there's nothing I can do. It's just that I find it ludicrous how a Heavenly High Immortal from the Hall of Gods would actually fear a mere Lesser True Immortal cultivator like me. From the looks of it, it seems like the Hall of Gods isn't anything impressive!"

"Lesser True Immortal realm?" Hearing those words, the trapped Elder Chou Huo immediately took a closer look, and it was only then that he noticed the change in Zhang Xuan's cultivation.

The battle earlier had placed him in such a dangerous position that he did not have the luxury of allowing him mind to wander at all. He never would have thought that Zhang Xuan would manage to achieve a breakthrough so quickly after leaving the Ascendant Cloud Sword Pavilion.
