Toaru Majutsu no Index: New Testament - Volume 18, Epilogue: Bursting Malice - Devil_in_Evil.

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.

Lin Wudao transmigrated and obtained an invincible system to bury corpses.

So long as he buried the corpses of the powerful, he got to take over what they had or what they touched as his bonus. What was more, those items he stood to win were the enhanced versions.

The minimum level was enhanced by ten times!

“You’ve buried the corpse of Jiang Taichu the Great Emperor. Your cultivation prowess just increased by 10,000 years!”

“You’ve buried the corpse of your fiancee, Jiang Qingxue. You get the essence of the immortal, which is enhanced by 100,000 times! It’s thus upgraded into the essence of harmony. You will become the Immortal Emperor after the extraction of it!”

……

Ever since he acquired this system, Lin Wudao had embarked on an invincible journey of advancing history and dominating the world.

A young boy named Bai Wu was saved and adopted by a thirty-something police sergeant named Xu Lan. It was love at first sight for Bai Wu, and once he started getting older, his heart yearned for a taste of the forbidden fruit – the romantic love of his adoptive father. The question is, will Xu Lan ever reciprocate? With deranged serial killers, parallel dimensions, time warps, dragons, and a bit of ancient black magic, Bai Wu and Xu Lan are caught in a series of crazy adventures while discovering what they truly mean to each other. This is a story of lust and madness!

“Missus, time to fulfil your duties!” Mu Yuchen demanded as he pulled Xi Xiaye closer with his arms intimately wrapped around her waist.

It was a meticulously planned feast for the powerful. Her fiancé had knelt down on one knee and proposed to her sister instead. Robbed of her right to her inheritance, she was prepared for the Xi family to throw her to the wolves.
As she slipped away from her family that had turned their backs on her, she found him — Mu Yuchen, the low-profile and reserved noble that ruled City Z and led Glory World Corporation.

“Mu Yuchen, let’s get married!” He looked up at her, then suddenly stood up.

“Where are you going?”

“Let’s go. Any later and the civil affairs bureau will be closed.”
