The dungeons appeared 3,000 years ago. New wealth and ways to gain power poured into the world, tipping the world’s power balance.

People rejoiced in their appearance. Now the poor could thrive, escaping poverty.

There were countless people trying to enter the dungeons. They formed a guild to manage them. We named them the Explorer’s guild.

All who ventured into those dark, evil places given a title to signify their status.

[Dungeon Scout]

A special occupation created to control the people who entered the dungeon.

A young orphan, adopted by dungeon knights and, would eventually follow in their footsteps.

His name was Vincent Schwartz, born in a fractured world of death and decay.

On the day of his 18th birthday, when children could ingest a special fluid and awaken.

Vincent awakened the unique [Summoner] class.

Able to summon distant beings that wielded endless power, able to perform terrifying attacks.

The only problem was the strange system, which appeared out of nowhere.

[The Demonic Choice System]

This system would give him random choices and give different rewards at different intervals in his life.

Would his system help him attain a wonderful life, filled with women he loves?

Perhaps the world will force him to fight, as the dungeon’s purpose remained hidden in shadows.

“Martial Arts World...” Death murmured, shocked by the turn of the events. How could he, primordial being of the afterlife, get tricked by a mere human? Not just a mere human, but also earthling, race that was weakest of the twenty realms. Death realized the extent of his mistake. An earthling had just jumped into the river of the reincarnation, where he definitely didn’t belong. It was too late. The damage has been done. The matter was now out of his hands. “Kiernan Hunter...” ... Remake of the Martial Arts System, and while the concept stays the same, the story is completely different. A few names, etc, stays the same, but mostly whole new story.

An ancient proverb from the Homo sapiens era once stated, “Light and darkness can never be united because they are natural enemies arranged since the creation of the universe.”The statement seems plausible, yet it may contain inaccuracies...——————————————Leon Kruger, a 22-year-old man counted among the three of humanity's heroes, is dispatched by the Holy Empire of Mankind to invade the territory of the Demon Empire—an enduring adversary of humanity for over 7000 years.Wielding the Great Holy Sword Zenith and commanding a legion of thousands of holy troops, he leads the raid on the Desert of Chaos, facing the elite armies of the Demon Race with unwavering valor.Even, he engaged in direct combat against the Demon Emperor, who was actively leading the war on behalf of the Demon Race!Unfortunately, he never foresaw that his offensive was a cunning scheme orchestrated by the Emperor of the Holy Empire.The emperor aimed to eliminate Leon, perceiving him as a threat to his position as the ruler.Furthermore, unbeknownst to him, he had been poisoned before setting out for war, leading to a catastrophic defeat at the hands of the Demon Emperor and resulting in his capture as a prisoner of the Demon Emperor.Envisaging torment at the hands of the notorious Demon Emperor after his capture, he was surprised to find that this foreseen ordeal did not come to pass!The Demon Emperor, unveiled as a remarkably beautiful woman, unexpectedly and without apparent cause, asked him to be responsible for abandoning their triplet daughters?!“Nani!
