Toaru Majutsu no Index: Genesis Testament - Volume 5, Chapter 4: If Someone Remains to be Saved – Final_Exams_“Handcuffs”.

When I woke up after a pretty crappy death, what greeted me was one of those famous fantasy worlds! I didn’t expect anything like becoming the strongest with a common job, or rising to the top with the weakest class…All I wanted was to live a slow farming life, but the world just wouldn’t leave me alone! And so I equally backstabbed good people and bad people alike, becoming a villain with a true sense of equality and just when I was about to retire and enjoy a proper life on a farm…“Master!”My former disciple at the evil organisation, currently the hero of justice came looking for me. Can’t you all just leave me alone?

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.

Gu Qingmo began to disguise herself as a man because of a word from her master.

Later, because of the words of my brother, I tried not to open my mouth if I could.

Later, I don’t know why the whole cultivation world is talking about the old master of Wanjianzong, the closed disciple of Xiaoyao Sanren, who is cold-hearted, taciturn, self-restrained and respectful, and who cultivates the ruthless way.

Mo Chuli thought so until she died in her hands.

However, since he was reborn and accepted as a disciple by Gu Qingmo, he discovered that——

Well said, cold hearted! taciturn! Self-denial!

It’s all an illusion!

Small snippet:

The day before Gu Qingmo was going to take Mo Chuli out for a training session, the headmaster made a special trip to Jianfeng and said to Mo Chuli, “Chuli, my uncle told you that if your master wants to go out in the future, you will definitely to follow.”

Mo Chuli: “Sect Master, why is this?”

Liu Qingbai: “Your master’s words are easy to offend people, so you have to keep an eye on it.”

Mo Chuli: “…”

- Description from novelbuddy

The Age of Gods has long since ended, their voices no longer heard on the continent of Douluo. Humanity, standing on the shoulders of legends from its history, advanced soul technology to inconceivable heights. The humans of Douluo invented weapons of mass destruction, mechanized armor, and living metals. With these advancements, they went on to conquer the oceans and discovered two new continents. To fuel these new technologies, humanity hunted the soul beasts to the very brink of extinction.

Once the dominant force of Douluo, the few surviving soul beasts now hide in the darkest recesses of their last sanctuary. The weakest have all been hunted, leaving only the strongest to scheme in the heart of the forest. The soul beasts, not willing to fade away, plot an uprising for their survival. In the midst of this, a god from a long forgotten era awakens in the depths of the Great Star Dou Forest to seek vengeance for the soul beasts.

As darkness encroaches from the abyss, hope is found in a young boy who holds a power beyond divinity within himself—Tang Wulin! Hope for both humanity and the soul beasts, as the bridge between the two. He finds his way into the fabled halls of Shrek Academy, where he learns to wield his prodigious powers, makes friends and finds allies, eventually rising to become a towering leader.

As he learns to harness his strength, danger lurks within the shadows as the various factions of humanity maneuver and plot to usurp Shrek Academy. Tang Wulin discovers the threat to the only world he knows as he sinks deeper into the intrigue. Meanwhile, camouflaged by the chaos and unbeknownst to the humans, the soul beasts’ plot continues to steadily advance.

To defend what he loves and reclaim what was lost, Tang Wulin must seek out the legacies of legends past and unlock the full might of the Golden Dragon King!
