Because of the exam, Xiao organization is determined to rob the child and forms a group to brush Konoha.

Because of the exam, Vortex Nagato, together with Madara Uchiha, vowed to plant the red flag in every corner of the ninja world.

At the beginning of the 21st century, twelve reincarnations shattered the void and returned to their hometown.

They preach the world and reopen the space of reincarnation.

Then……

“The Republic of East Asia announced that it will fully implement a five-year spell casting and twelve-year simulation mage training policy.”

“The Republic of East Asia has announced a new change in the marriage law, making it legal to marry someone you call upon after meeting the adulthood conditions of your respective race.”

“The Republic of East Asia announced that the East China Military Region No. 1 Mobile Armor Brigade was established, and the special humanoid mecha “Gundam” officially joined the campaign.”

“Congratulations from the United Kingdom on this, the upper hero Arturia Pendragon will visit Shanghai next month”

“In the far east of Japan, the ignition of the wave engine failed, or seek energy assistance from the East Asian Republic.”

“Space cracks have been discovered in the Chernobyl region, alien creatures have ravaged the Chernobyl region, and the Russian Defense Forces have entered the battle.”

Four years after twelve reincarnators changed the world, Li Ping entered his own battlefield for the first time.

PS: Although the introduction is like this… but in fact it is written about two thorns + machine battle + movie + mythical stew…

- Description from novelbuddy

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.
