Magika no Kenshi to Shoukan Maou - 1.1.4 — The Swordsman in Magic Division

An orphan dies while saving a bus full of children. For saving countless lives, the Universe grants him the opportunity to transmigrate to another reality.

There he realizes his dreams of supporting his new family and opening a company that will shake the foundations of this new world. He will be known as the MasterChef of the gods, a superstar singer, the best Mangaka to exist, the best Director, the businessman of the millennium and many other adjectives.

When Su Lin transmigrated into a Rebirth novel, he found himself playing the role of a villain.

He then came to know that Ye Feng, the Protagonist, will be reborn in three days and he began to alter the plot, leaving the reborn Ye Feng dumbfounded.

Goddess Bai Yueguang’s attitude towards him has now changed.

Even his childhood sweetheart began to treat him coldly.

The reborn Ye Feng who intended to reach the pinnacle of his life, would never have expected he’d sink into oblivion.

On the other hand, Su Lin, who was well-versed of the plot of the world and the cliches that are bound to it used them to his advantage, and flourished.

His story had become much more interesting.

The one who had been reborn, the supreme medical saint who had come from the mountains, the one who had returned from the military, and many more Protagonists were all dealt by Su Lin, and thus he had become a legend.

An ultimate warrior, the one and only Alchemy Emperor, Ling Han, died in his quest to achieve godhood. Ten thousands years later, he, with the ‘Invincible Heaven Scroll’, was reborn in the body of a young man with the same name. From then on, winds and clouds moved as he set himself against the uncountable geniuses of this new era. His path of becoming a legend has begun once more. Of all eras underneath the heavens, I am the strongest!
