I’m Really Not The Demon God’s Lackey - Chapter 10 You Failed?

Uchiha Yu traveled through and came to the crisis-ridden Naruto world.

Looking at the scarlet writing wheel in the mirror, Uchiha Yu nodded with satisfaction: “Well, everything is going well so far… smooth hammer!”

Looking at the calendar on the wall, Uchiha Yu felt the malice from this world…

In order to save his life on the night of the genocide, and even take food from the tiger’s mouth, Uchiha Yu decided to train Pokémon hard from today!

Uchiha Yume, use illusion!

A trainer: “Referee, Yu’s dream demon is illegal, it uses illusions!”

Uchiha Yu: “Humph, you absolutely cannot escape this technique!”

Deidara: “Explosions are art!”

Uchiha: “My Pangyan monster’s art is better than yours!”

What was originally an ordinary day, suddenly became a historical turning point. Enormous, mysterious Cubes appeared all over the world without warning and as if Judgement Day’s spears, inserted themselves into the blue planet.

From inside the enormous Cubes, endless streams of monsters gushed out alike raging tides, utterly defeating the unguarded armies of each state in the blink of an eye.

In order for humanity to preserve its final embers, the heads of states issued orders of retreat, to no longer attack the Cubes but rather to cling to remote cities, which they turned into self-sufficient survivor bases and around which they built 100-meter-tall Walls of Life!

Many years later, while bearing the heavy weight of history, the first expeditionary force brought back a world changing piece of information. The Cubes possessed exceedingly high intelligence and they regularly transmitted mission instructions to humans nearby. The mission rewards were incredible.

Since then, humans rushed out of the confines of the walls and once more set foot on the wasteland!

Born into a wealthy family, Gu Shenwei was spoiled and carefree. However, at the age of 14, his entire family were brutally murdered, and he was caught by some bandits who sold him into slavery. As a slave boy, he entered Golden Roc Fort by chance and found the man who had slaughtered his family. He endured insults and worked hard to improve his kung fu while working as a slave boy. He learned from and plotted against his enemy under the enemy’s nose. He became increasingly ambitious as he became more and more powerful. He would only be satisfied if he completely destroyed his enemy—by fair means or foul. Gradually his bitter experience turned him into a totally different person.

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?
