HxH : Pokemon Master - Chapter 73: A Sure-Hit Skill

Lou Yao Yao wasted her life fighting over a man, only to find out he wasn’t worth it in the end. Because of this man, she accidentally killed her rival in love, and even ruined the man who had always been watching over her.

My name is Qin Jue. At only 16 years of age, I'm already the youngest person to ever become an uncle-grandmaster in the Xuanyi Mountain Sect.Also, I'm the strongest being in this entire world!But unlike other transmigrators, I want nothing to do with the outside world and wish to live a leisurely life on a cliff behind the sect, sipping wine and singing songs.That is until one day, a mysterious girl appears in front of my yard…Join Qin Jue as he deals with sneaky sects and greedy, hostile clans, all while raising a "weed" to sentience and creating heaven-defying spirit-energy "guns".

Reincarnated into a land of cultivation, Yuan Zhou uses his Earth knowledge and assumptions to become a genius under the heavens for both business and cultivation. However, he walks the path of defiance, exceeding all rational cultivation bounds. His business ideas struggle against the stagnant culture that pervades the land, but the things he doesn't lack are his drive for immortality and power.

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!
