A simple life—legendary swordsman, Knight of the Round Table, Lord of Camelot, Davian Slyrik.

Morgan: If I can’t have it, no one can.

Artoria: When the road has reached its end, Davian… I will avenge you.

Mordred: If I can’t take Britain from your hands… then let it burn!

Davian: Tatakai! Ichimo tatakai! (Fight! Always fight!)

(High IQ + Ruthless Kills + No Female Lead + Not a Saint + Mortal Cultivation Style + Cold-Hearted)

For hundreds of thousands of years,

Why has no one ascended to immortality?

And those who did—why did they all fall?

Chen Changsheng, in pursuit of the eternal path,

uncovers a cultivation world built on lies, schemes, and betrayal.

So he abandons mercy.

With cruel and decisive methods,

he tears open the secrets of the cultivation realm,

slaughters all who stand in his way,

and forges the righteous path… with his own hands!

Ed, who has transmigrated to a bizarrely mutated other world, relies on his innate ability to summon "players" from his original world to work for him. He describes his creations as "magical nuclear-powered donkeys"—a concoction of flesh, bone fragments, a nearly complete brain, all held together by vines and infused with a soul from another dimension. He affectionately calls them the "Pieced-Together People."

Just as Ed is planning to relax and let his players do all the work, he discovers that things are taking a strange turn. His players reveal that their own world is being eroded, and even more shockingly, the skills they learn in this game-like world can be used in reality. As nations from their world begin sending agents to learn from him, Ed, who is mistaken for some kind of cyber-instructor, finds himself reluctantly pushed into a position of great power. He exclaims, "How can I possibly take on the role of the Lord of Order? You've all brought me nothing but trouble!"

Prisoner of War Demon King: I am not a succubus, and I will not have children with you, don't even think about it, it's absolutely impossible.

By accident, Chen Ping transmigrated into a world of cultivation and thought he was favored by the heavens—only to be harshly taught by reality.

Born with crippled spiritual roots of all five elements, even the righteous sects wouldn’t let him work as a servant!

Isn’t this basically forcing me to join the demonic sect?

But who the hell cultivates in the demonic path for 80 years and still can’t beat a black dog?

As his lifespan approached its end, he was still stuck at the first level of Qi Refining.

Chen Ping was in despair.

He smashed his alchemy furnace and said: "Screw it, I’ll just get married and have a kid!"

If I can’t become a Foundation Establishment cultivator, then my son will!

Yet unexpectedly, on his wedding night, he unlocked a golden finger (cheat ability).

From that moment, with crippled five-element roots, he became the number one in the cultivation world!

But little did he expect beauties from all realms to show up one after another...

Seductive married woman: As the saying goes, rising in cultivation...

The heavens and all realms exist for countless years, and no one knows the day of their origin and end!

When the origin of the "Abyss Campaign" failed, countless demons perished in the place of origin!

Wang Mo, who accidentally obtained the fragments of the abyss world and the supporting abyss's incomplete will, will continue on the road to war!

Heavens and all realms, he's coming!

Ivan never imagined he'd one day lead his family to establish the greatest wizarding school in human history.

After all, when he first entered the Wizard Tower, he was a mere underachiever, failing nine out of ten subjects.

Potions, anatomy, sorcery theory, species research...

Ivan knew nothing about it.

His only strengths were playing cards, dice, drinking, and helping his instructors fill out expense receipts.

Until...

his family sent several ambitious young men.

[Congratulations! Through your instruction, your family members have mastered the [Basic Meditation Method]. You receive the Advanced Meditation Method [Starry Sky Meditation].

[Congratulations! Your family members have mastered the Level 2 Spell [Skeleton Warrior]. You receive the Improved Spell [Summoning Undead Knight].

[Train family members and gain advanced knowledge]

Years later, when Ivan personally founded a wizarding school unique to his family, he suddenly realized that in the pursuit of truth and knowledge, the efforts and talents of others are far more important than one's own...

Summary: Would you like to become a succubus? Even if you'll be misunderstood and no one will read it, I'll still build a deck. It doesn't touch upon the existing world of D&D, uses a mix of settings from various editions (except for 4th edition), minimizes data, and includes some random monsters created by the author...
