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!

Sovereign Chen Yong was one of the Three Sovereigns of the Otherworldly Demonic Tribe, and he was the most authoritative and powerful of them. Most of the major decisions regarding the tribe were made by him, thus building his reputation as the number one expert of the Otherworldly Demonic Tribe. How could he be the youth who had been addressing him as 'Young Master' all this while?

If they really were the same person, then… what was the identity of Luo Ruoxin, whom he addressed as Milady?

In that instant, Zhang Xuan's body turned ice cold. He did not dare consider that possibility.

He had heard from Yang shi in the past that the strongest Otherworldly Demon Emperor had come to the Master Teacher Continent, but his whereabouts had been a mystery to all. Who would have thought that the other party had actually been by his side, serving as Luo Ruoxin's subordinate?
