A man who was once called the world’s strongest agent ended up becoming a teacher after his retirement, to train a new generation of agents. After many years of training his disciples, he was killed at the age of 60 by a secret organization’s ruse and was reincarnated in another world with his memories intact. Though he was surprised by the existence of magic and the strange species in that world, he quickly adapted to his condition as a newborn and took advantage of it. He acquired special magic and gained a massive amount of strength thanks to his rigorous discipline, in order to reach his goal: Resume his career as a teacher which he left halfway through in his previous life. This is the story of a man, who, based on the memories and the experiences of his previous life, became a teacher who travels through the world with his students.

In the next life time, he would absolutely not become an author.
He would once again be cursed to the danger of crossing over into a book.
During the time when he broke free of his shell, what he first saw was just the handsome, handsome male lead that he had written.
During the time when the male lead was pinching the small soft flesh of his neck, it was also his first time hearing the male lead’s voice.
“Return goods,” the male lead said in this way toward the vendor stall’s owner.
Pei Bufan: “…… meow?”

“Rising to the top was like a game, and now I have become the Final Boss of the entire world!” -Noah Black.

Liang Sheng travels through another world, starting with a child with dull talent.

Chizi is dull: sincere heart, perseverance, extremely slow cultivation speed, no bottleneck in the world.

But what if there is no bottleneck in the world?

Cultivation speed is extremely slow, it is rubbish.

But when he practiced the Changchun Kungfu, which was only at the ninth level, and broke through to the tenth level and extended his life for another 20 years, he suddenly realized.

It turns out that this is the true world where there is no bottleneck in any method, and any method can break through the limit and continue to practice.

That being the case, one health-preserving exercise is not enough, so I will practice ten!

If ten is not enough, then twenty!

All in all, I want to live forever!

PS: There are already high-definition novels with over 10 million words, “The World Doesn’t Know How Strong I Am” and “The Ferryman in the Yellow Spring”.
