Getting Beaten in Another World Makes Me Stronger in Real Life, Now I'm Invincible

[Pain-Eating System + High Martial Arts + Apocalypse] [Otherworldly Feedback + Invincible in the Real World + Ruthless and Decisive]

To save his terminally ill younger sister, Lin Feng ventured into another world and bound himself to the Pain-Eating System.

From then on, every injury he suffered in that world was transferred in full to his body in the city!

The powerful figures of the other world saw him as an ant and trampled him at will;

The martial arts masters of the city mocked him as a nobody and tried to suppress him.

They had no idea that when Lin Feng lost an arm in the other world, he could return and knock down a skyscraper with one punch;

When they burned his body with raging flames in the other world, he could return and command thunder with his bare hands!

As the passage between the two worlds opened completely, the Netherkin army descended, and all life withered...

Lin Feng, once scorned by everyone, stood at the crossroads of the worlds.

He gazed at the demons filling the sky and slowly clenched his fist:

"For every bit of pain you've ever inflicted on me,"

"today, you'll pay with your lives!"
