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!

The assessment on the second floor wasn't regarding beast tamer, formation master, or the other supporting occupations he was more skilled in but blacksmith.

As soon as he entered the room, he immediately saw a young man standing before a cauldron. Holding a fiery red hammer in his hand, he struck a metal ingot relentlessly. Gradually, the metal ingot took shape, and a cold glint reflected off of it.

The Tower of Master Teachers required him to choose eight different supporting occupations, and just so to save him from putting in additional effort in the future, the supporting occupations that he chose were all those which he hadn't obtained the 8-star emblem yet.
