One day in the faraway Blue Boorish Mountain inexplicably appeared groups of scoundrels who came to reside there. It was said that those scoundrels came from the You Kingdom, Yen Kingdom and many others due to their failures in battle. And due to its dangerous terrain, no one had dared to conquer the Blue Boorish Mountain. As a result, this place obviously became a paradise to the scoundrel and thieves. They resided there and ruled the place.

They had also built up the Illusory Perennial Domicile, which meant a place that was their lifetime home. There was a group of scoundrels who had appointed themselves the Great Nine Bandits, and they were seen as the best baddies in the area. They built up a school in which the children of the Illusory Perennial Domicile would come and study only survival skills.

In such a small place appeared an orphan student named An Zheng who also came to study there. He was really a useless orphan in the people’s eyes due to his cowardice. They even said that he was a chicken who did not dare to do anything for himself even in fighting for himself, and no one cared about such a coward except a ten-year-old child, Du ShouShou, his only friend. As a result, he was the center for such baddies to cause trouble.

However, no one knew that orphan An Zheng would change his life forever as he went to a dead end.How powerful was that orphan? How much effort did An Zheng have to make in order to satisfy his passions of the devilish elimination? How would the life of his friend, Du ShouShou change after his after death spawn? And might the Great Nine Bandits be the invincible ones? Was he good or evil? Was his power strong or weak?

Was his world in perfect order or chaos? They were all questions that the little child An Zheng needed to discover during his journey.“Bring happiness to loyal people but chide the evil. However, if the treatment goes wrong, law will become a tool for the evil to force the good, preventing executors. Find a repugnant gateway to pass. Great things win cruel tricks. We learn from the idea of God but we reject the power of Him.”

Endless sky and infinite space, the cosmos isn’t some paradise waiting to be found, it is full of darkness and danger, death and terror of the great unknown. However, for that glittering swath of blue, we have no fear! For the longevity of men, we have no regrets! Nothing shall stand in our way because it is finally our time, our age! The age of cosmos exploration!

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.

“Emperor 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 Lord 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!
