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!

"I have a Spatial Top with me, which is able to gauge the stability of a space and determine one's level of control over a certain space. Whoever is able to keep this top spinning for the longest time possible will be deemed to have the deeper understanding of space!"

As Nangong Yuanfeng spoke, he flicked his finger, and a top of roughly <anno data-annotation-id="23b5e5fa-4143-470d-f126-0f25440bf73d">a chi long</anno> appeared before everyone's sight. It stood motionlessly on the elevated platform, and even though there was no energy emanating from it, there were still many slight dimension rifts around it.

The presence of dimension rifts hinted that the space was not stable. In order to get the Spatial Top to stand, one had to reconstruct a stable space, or to put it in simpler terms, mend the dimension rifts around.
