Something is not right!Opportunities?I've taken them, all of them!His, yours, they are all mine, Xie Jiuniang's!Before she knew it, she had trampled over all the privileged talents, challenged all the big shots, becoming the most formidable name, and rolled up into the number one person in the Cultivation World!

A path of survival, intertwined with the doctrine of both Immortal and Martial Arts, every punch strikes true.In the chaotic world of Martial Arts, power reigns supreme. To survive, Chen Yi exhausted all of his family savings on learning martial arts, only to startlingly discover that the Broken Jade in his mind was also accumulating energy, enabling him to possess the ability to cross into the Immortal Cultivation World.The moment he crossed over, merely inhaling the spiritual energy accelerated his martial arts progression at an astonishing rate.Not to mention the dazzling array of martial methods, pill talismans, arrays, and various cultivation oddities inside, all of them significantly boosted his strength!Since then, Chen Yi, who held sway over two worlds, began his days of striving for upgrades and growth, unknowingly becoming a top-tier existence in both worlds.And later, he found even more astonishingly, that there was such a mysterious connection between these two worlds.

The world was once at war with 10 alternate worlds. This was known as the Concept War and our world won 60 years ago. All of this was concealed so no normal people are aware of this fact in the current time.

After the death of his grandfather, the high-school student Sayama Mikoto is suddenly summoned by the giant corporation IAI. He learns this world is headed for destruction due to the acceleration of the Minus Concepts. To prevent this, negotiations must be undertaken with the survivors of the other parallel worlds so their 10 concepts can be released.

And so Sayama is caught up in the final battle to clean up after the Concept War which left behind so much enmity.
