Toaru Majutsu no Index: New Testament - Volume 7, Chapter 3: ??? Agitate_Halation.

Humanity was finally recovering from the wave of an unknown Mana Apocalypse that had turned the world upside down.

A world where Science had married Magic. Advanced technology had mixed with magic spells.

Monsters took over the world and remarked earth's cities and countries as their kingdom. Half of humanity took the path of magic to survive, and half of humanity took the help of their advanced technology to survive. But what if humanity turns against humanity? The world split into two groups- The Science Users and The Mana Users

Hitori, who happens to be in the Mana Users group hates magic and spells. Saibai Hitori's passion, pleasure, and happiness lie in gaming. He unlocks the solo Cultivation System and the ability to cultivate in and outside the most popular game.

[The Emperor of the Apocalypse] is currently the best VRMMORGP open-world, kingdom-building survival game in the world. In this apocalyptic world, players try to clear dungeons marked on the map to mark that as their territory and eventually become the one and only Emperor of the Apocalypse.

In times of destruction, trusting someone will only destroy you. Players and guilds started attacking each other in the game. Guild Vs. Guild, Player Vs. Player, Player Vs. Environment, Realm vs. Realm. Everything is on, everything is going down.

Hitori's goal is to unravel the secret behind his parents' death and become the Emperor of the Apocalypse.

In a world where humans evolve and survive, only I cultivate and conquer.

Yuan Xiao was reborn. Only after her death did she discover that she was living in a book. In the book, she was a fake heiress who did terrible things and made the real female protagonist look like a good person. After being reborn, Yuan Xiao decided to become a scholar. As long as she studied hard enough, she’d repeatedly get the opportunity to draw prizes and stop herself from being controlled by the storyline. She wanted to change her life. Yuan Xiao did not want the terrible fate of her past life to repeat itself.

She wanted a life that belonged to her! Other students looked down on her. She made sure to win as many prizes in competitions as she could and consistently claimed the number one spot in school. Some people suspected she might have forged her educational accomplishments due to her young age. She directly solved the toughest questions in the world to prove those people wrong. Did somebody mock her for not being able to do anything else but study? She’d show them her world-class piano-playing…

Yuan Xiao went down the scholarly path and never looked back. She was no longer the bad student she used to be. The smart student in school, who nobody dared to offend, forced her into a corner and nervously gave her a lollipop. “I just gave you a lollipop, the thing that I like the most. When will you be my girlfriend?” Yuan Xiao tapped on his chin and chuckled. “I’ll be your girlfriend if you get into Q College with me.”

Living in this apocalyptic world full of zombies and monsters, the rich rely on technology and the poor rely on mutation.

Shen Shanwu, 13 years old in appearance but 31 years old in reality, is a mutant that can alter his own appearance. Although he looks like a child on the outside, his wisdom is not very good. One day, he was just passing by when he was suddenly forcibly adopted by a major general, whom he didn’t know where he came from.

He resisted, but when he looked up, it turned out to be an old acquaintance.

The little boy, who could only hide behind him and cry, transformed into the unsmiling, cold, and tough man in front of him. And that expression of seeing a dead beloved is really unsightly…

Shen Shanwu: Can you smile?

Jing Huan: After Shanwu died, I couldn’t smile anymore.

Shen Shanwu: …Who? Who do you think is dead?

It took a long time before he found out about it. He found Jiang Huan crying and holding Shen Shanwu’s nameplate in the middle of the night and told his adopted son how good Shen Shanwu was… All of this…was seen by Shen Shanwu himself!

Jiang Huan (raising his gun): Since you have seen my embarrassing side, then I can only marry you or kill you.

Shen Shanwu: …

Shen Shanwu: Marry, marry, marry! I will recruit 800 zombies to carry you home!

Lin Yue: “There are too many boxes and there is no room in the inventory. Do I have to upgrade the shelter to build a warehouse? Oh, it’s so annoying.”
