The Black Book: Seven Deadly Sins - Chapter 3: Curiosity Killed the Cat

What would you do if your entire world were turned on its head? A Primordial System buzzing in everyone’s heads, displaying strange screens and other displays in their visions. Being thrown into a tutorial before entering your first System Event broadcast across the universe. Returning back to your home after the System Event to realize that it’s been filled with Gates leading to monster-filled domains, a good number of which have already broken and released their monsters into the world. And learning that the abilities every human being has – abilities that have led to the current structure of society – are nothing but the root of their Skill Trees. The very first skill in their Skill Tree out of many. Well, Ashley doesn’t know. She doesn’t remember anything other than some basic common knowledge from before waking up at the start of the tutorial with amnesia. So why should this change anything for her? Other than her finding out about the blood bestowed upon her by a certain primordial and her own Skill Tree. One with just a single skill. A skill to unlock the skill trees of those she kills. To assimilate. What to expect: Skill Trees, LitRPG Apocalypse, Skill Tree Assimilator(the ability to take the skill trees of those the MC kills that she can unlock through Skill Points without getting the skills right away), Livestreamed Dungeons, Livestreamed Public Battles and Events, Chaos Magic, Varied Magic due to Skill Tree Assimilator, and the MC does not start off strong in the start and only grows strong as she assimilates more skills from those she kills, the MC starts out without any memories and few emotions and slowly gains them throughout the series. What not to expect: I do not write romance(for the main protagonist), there will be no harem, there will be no reverse harem, and do not expect a really strong MC at the start of the story as she has to grow into that role.

She was stupidly in love with him. Because of him, she became rude and unreasonable, overbearing, jealous, insane. But he did not spare a glance to her. Married for two years, he didn’t favor her once, letting her become the laughing stock of the whole world. Eventually, she ended up in an affair, leading to her tragic death.

Zavier met Cosmic Consciousness after his death. He was satisfied with every system that Cosmic Consciousness exhibited, so he wanted all of them. Surprisingly, the Cosmic Consciousness obliged him.

Zavier was reborn in an isekai full of magic and alchemy. Now, he had many routes to upgrade. Interestingly, to coordinate these systems, Cosmic Consciousness gave him the gift of being able to duplicate himself. He could clone a finite number of himself to manipulate these systems.

Magus, Alchemist, Mesmer, Tamer, Hunter, Vampire, Werewolf, Dragonknight, Necromancer.....

By the way, it wouldn't appear NTR or some bullshit harem of courtships. MC of course will have harem but not for cliches.

In the age of Mecha for everyone, people could travel to the Endless Abyss to gather materials, enhance and forge their own Mechas, and thus wield the power to destroy heavens and earth.Jiang Chen had transmigrated and awakened the talent [Undying Barehand]. Once his Mecha shattered, he could permanently absorb its power and attain a multiple enhancement.…At the bottom of the abyss, the ancient demon god exerted great effort and finally broke the titan Mecha, but from the shards extended a hand that held down its head.“Congratulations, you’ve unlocked my restraints.”
