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 device to select the winning number was basically a massive roulette wheel with the numbers one to a hundred on it. There was a needle above the roulette wheel that would start spinning randomly as soon as the device was activated. As it was controlled by a special formation, it was impossible for anyone to tamper with the results.

The needle would first be spun right before the crowd's eyes, but after turning a few rounds, a formation would be activated to conceal the needle from sight. Once the needle came to a halt, the crowd would be able to start buying the numbers that they thought could be the winning number.

The process of buying a number was simple as well. It was similar to those olden days casinos where you simply place your money on the number you are buying on the table.

All it took was a glance for Zhang Xuan to figure out what was going on.
