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!

What he was going to take was the master teacher examination, how did 'Empire Building' come into the picture?

Master teacher examinations were centered around nurturing and guiding others, it shouldn't have anything to do with governance or anything of the sort.

Noticing Zhang Xuan's doubts, School Head Mo asked with a smile, "Principal Zhang, based on your journey here from Tianxuan Kingdom, what do you think the greatest difference between a kingdom and an empire is?"

"Difference?" Zhang Xuan frowned. He contemplated for a moment before replying, "The tier of the local Master Teacher Pavilions!"

Conferred Empire, Tier-1 Empire, Tier-2 Empire, Conferred Kingdom, Tier-1 Kingdom, Tier-2 Kingdom… The main difference between nations of differing classifications was their national strength.

And the biggest contributing factor to the difference in national strength was the Master Teacher Pavilion!
