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 storage rings of the two Kings could easily qualify as a treasure vault. Putting aside the many powerful weapons and potent pills, there were more than ten thousand high-tier spirit stones within!

Most likely, these are the resources they were given for the mission, Zhang Xuan guessed.

Given that the Otherworldly Demonic Tribe had paid a heavy price to allow two Otherworldly Demon Kings to bypass the seal and enter the Subterranean Gallery, there was no doubt that they were on an important mission. Naturally, the Otherworldly Demonic Tribe would have offered them the best resources so as to ensure that the mission would be successful.

However, it seemed like it had only ended up benefitting him.

Their superiors probably couldn't have imagined that the many subordinates they had dispatched to the Subterranean Gallery would have been wiped out by a mere Nascent Saint lad before they could achieve anything at all.
