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!

"Battle?" Zhang Xuan frowned in incomprehension. "The Otherworldly Demons actually dared to appear in the open… not to mention, they are even adhering to the rules?"

Based on what he knew, etiquette and such meant nothing to the Otherworldly Demons. Driven by their bloodlust, they were mostly interested only in slaughter. Thus, it was extremely bizarre for an Otherworldly Demon to actually issue a formal challenge.

More importantly, there were many powerful master teachers in the Pavilion of Warm Spring… Given that the deep-seated conflict between the master teachers and the Otherworldly Demons had gone on for tens of thousands of years, it was inevitable that both sides would have some loved ones who had been killed by the other party. Was the Otherworldly Demon not afraid of being killed running over here like that?

"It's not that they want to adhere to the rules. They have no choice but to do so!" Sword Saint Xing explained with a bitter smile.
