Zither Emperor - Volume 4 Chapter 24.3

They say luck is an uncontrollable force and karma is nothing but a cycle of cause-and-effect that depends on one's deeds. But what if luck somehow really could be manipulated while the way karma worked could be changed?

With the appearance of the Realm Games where every life became worthless and Artifacts that granted various powers, humankind was pushed to the ultimate path of evolution for one last time!

Raven, a simple young man, was also forced to walk on such a path, which with his cursed bad luck became even more difficult than for others!

However, what he did not know at that time was that it was not only humanity that was coerced with such a cruel fate but every living being in the far cosmos too!

Come and follow Raven on his journey and witness how he struggles his way through hardships and how he shifts his seemingly already decided fate that the Gods have destined him to walk from the very start!

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!
