MTL - Rebirth 2002: Nano Life - v3 Chapter 40 RISC-C

A lecherous army special task force soldier from 21st-century Hong Kong is selected to travel back in time, choosing to go to the Chinese Warring States Period. Unfortunately, the time machine runs into an error during the experiment. With no foreseeable way to return to the present, he must use his combat skills and knowledge of history to thrive in his new life in the year 251 BC.

The world changed the day that cracks appeared in the sky– suddenly monsters named『Demonic Beasts』appeared and began to rampage, attacking people.

Meanwhile, girls called『Magical Girls』began to appear to counter the demonic beasts. As they defeated the demonic beasts, gradually people’s lives gained a semblance of composure.

–but when there is light, there is also darkness.

In the corner of an alleyway, a boy who had been attacked by a demonic beast was dying. His voice begging for help did not reach anyone and his body refused to move.

「Boy. Do you want to be saved?」

Looking into the boy’s face, a black cat began to speak to him.

The boy nodded firmly to the devilishly sweet invitation, in response the black cat mocked him.

「Is that so—then I’ll【Haunt (Save)】you」

—on that day, a『Magical Girl』was born in a place that no-one knew.

『She』never laments, no matter what the future may bring.

A 30-year-old NEET is reincarnated into the body of an otaku that choked to death on instant noodles. As he comes to grips with his new life, he realizes that this world is subtly different from Earth. The denizens of this world are far better looking, and this new world also possesses futuristic technology as well as mysterious Yin Yang masters!

Jiang Lin crossed over, he became the tragic little cannon fodder in the book.

The little cannon fodder relied on his good looks, and there was no man in capital who hadn’t been seduced by him.

He was a well-known playboy in capital, an existence that everyone despised.

Only Jiang Lin who became the cannon fodder knew what kind of life the cannon fodder lived.

The little cannon fodder’s father didn’t care, his mother died early, and his stepmother treated him harshly. There were also two stepbrothers and a “beautiful and kind-hearted” heroine sister in the family.

The first stepbrother robbed him of his position as a companion of the crown prince, and the second stepbrother robbed him of his qualification to be a student of the Imperial Academy; in the end, the heroine sister arranged him to marry a man who was about to die.

From anyone’s point of view, what Jiang Lin took was a death script. But Jiang Lin held the space in his hand, who was he afraid of?

So——
Jiang Lin made a great contribution in front of the heroine, and successfully regained the position of the eldest son of the Hou family from the hands of his two stepbrothers.

Jiang Lin successfully solved the famine and became famous all over the world as a Marquis and held the nobility.

As for the dying man Jiang Lin married, not only did his legs recover from the poison, but he also became a fearsome General, the God of War.
