[The First Emperor, Unifying the World Under Heaven][By the Mandate of Heaven, May His Reign Be Long and Prosperous][Cai'er, Childhood Sweetheart]

Yan Qianqiu travels to the Holy Demon Continent.

He was diagnosed with full innate spiritual power at the age of three, making him a chosen one of the gods in the cycle of reincarnation.

The Spirit Furnace that gave birth to the Six Paths of Reincarnation divides the power of the six paths.

The Way of Heaven and the interaction between Heaven and Man are governed by the Heavenly Sword, which controls the destiny of all things.

The Asura is unparalleled in slaughter, wielding the Asura Purgatory Sword to judge the lives of all.

The Human Path: discerning and identifying… The Animal Path: taming the ancestor of all beasts… The Hell Path: devouring the demonic body of heaven… The Hungry Ghost Path: controlling the spirits of the dead.

Yulong Pass

Yan Qianqiu wore the Devouring Demon Armor, carried the Slaughtering Hundreds of Heads on his back, and held the Heavenly Dao Heavenly Question Sword in his hand. Behind him, all beasts paid homage, and all spirits bowed in reverence.

He looked at the Demon Emperor, his voice resounding through the heavens, "The overthrow of the seventy-two Demon Gods begins today!"

...From then on,

The rebellious demonic dragon clan became the beasts seated by the First Emperor, bowing and receiving his divine favor.

Lu Xuan transmigrates to a high-martial arts world and activates the multiverse trading system!

As long as you keep trading with the myriad worlds, you can become stronger!

Lu Xuan smiled faintly: "Welcome to the City of Myriad Realms, where you can find everything you desire..."

And so, many years later.

The Emperor of the Ming Dynasty declared: "I am the true dragon! The Mad Death Camp, obey my command! Under heaven, all land belongs to the Emperor!"

Wang Yuyan: "Cousin, let's not contact each other anymore. I'm afraid Lu Xuan will misunderstand..."

Ferryman Zhao Li: "You're Hades Cha Cha, right? I'm really angry right now~"

Orochimaru: "Hehehe~ Uchiha Madara, do you also want to dance?"

...[Cheat Code] +[Counterattack] +[Enlightenment] +[Semi-Invincible] No way, no way, I've already become an Eternal Emperor, and the cheat code for transmigrators is only just arriving? -- Fang Yuan transmigrated to the Desolate Chaos Universe, experiencing 86,000 Chaos Eras before achieving Eternity and becoming an ordinary Eternal Emperor. But he lived a stifled life... However, with the cheat code, the situation changed! ...In the Desolate Era world, I don't care about you, but what will you call me outside of the Desolate Era? [Absolutely eternal existence in all dimensions of time and space]! -- Zhang Zhiwei from Under One Person: Emperor Dao Ancestor above. Xia Lan Po Zhen: Please, ancient Xia Lan seniors, take action to slay the ferocious beast! Bad Guys Yuan Tiangang: A true immortal descended to earth. Swallowing the Stars Zuo Shan Ke: A Hunyuan life form! Soldier Assault Gao Cheng: A war god?! I knew you were bragging. Star Journey Mai Lin: The unfathomable master of the Rainbow Sea! [Ah, sounds so good!] It's much better than those pitiful, weak, and third-rate ordinary emperors! ...Super Beast Force, Chinese Boy, Divine Soul, Seer, One Piece, Naruto, Super Soldier, Spirit Master, Pirate Hero, Armor Hero... If you ask why they're all low-power worlds, that's because of the cheat codes. I, the Primordial Chaos Emperor, have cultivated for so many years, what's wrong with enjoying myself?!

Official Introduction: Now approaching you is: Muzan's nightmare, the destroyer of the Twelve Demon Moons, the head of the Infinity Castle demolition office, the most righteous person in the Demon Slayer Corps, Sabito's savior, the eternal absentee of Kanae Kocho's tea party, Giyu's good senior brother, the founder of Fist Breathing, and a grandmaster.

Willow branches provide shade, that's it!

Kanae Kocho: "I invited him to a tea party ninety-seven times, and he refused ninety-seven times. He's so gentle."

Shinobu Kocho: "Why should I be trained by iron fists? It's infuriating, sister!"

Akaza: "A powerful person, the best in physical combat."

Muzan Kibutsuji: "A monster who destroyed all my Demon Moons with his bare hands and blasted the Infinity Castle to pieces, you call him human?!"

Unofficial synopsis: Yagyu In transmigrates to the world of Demon Slayer, but the system believes he is in the world of One Piece and identifies him as a Marine.

You can earn Navy Points and rewards by doing things that are in line with the Navy's rules.

Yagyu In: No, buddy, is this right? Where did this pirate from the Demon Slayer world come from that I need to catch?!

Pirates are attacking! Strike immediately to capture or kill them!

Looking at the man-eating ghost before him, Liu Shengyin realized that the system had gone mad.

From then on, the Demon Slayer Corps had one more instructor who liked to smash people's heads with his iron fist of love.

This book is also known as "Left Fist's Overpowering Entanglement Deals High Damage, Right Fist's Overpowering Entanglement Deals High Damage," "Three Punches Shatter Evil Spirits, Sir, I'm Just an Ordinary Person," "Overpowering Aura is Also Qi, and Qi is Breathing Technique!" and "Muzan, Are You Hiding Well? The Marine Admiral is Coming to Get You~"

Note: This book is a crossover anime/manga series, and will later explore other worlds.

Haruto completed the Ghost Swordsman training with great difficulty and went to Fujiki Mountain to participate in the selection. Suddenly, a line of comments passed by his eyes: Such a handsome guy, it's a pity that he will die in the next second.

A moment later, he was killed by the hand ghost hiding in Tengxi Mountain, who pierced his heart.

Coming to Fujixi Mountain again, Haruto, who thought he was dreaming, saw another line of comments before his eyes: The guy is very strong, but it's a pity that he can't save Santu.

Xuantu? Who is that?

I'm just an amateur demon slayer swordsman who has been practicing for two and a half years. Don't pin your hopes of saving people on me!

This book is also known as "Although I haven't watched Demon Slayer, I have been spoiled by the barrage", "I only have one frame of the original painting, and I rely on the barrage to argue with Muzan", and "What is the official complaining tool?"

Key points: There is only one female protagonist, the female protagonist is tolerant, no important plot characters are killed, and the official pairing is not broken up.

Contents: barrage comments + the protagonist's rich inner thoughts, which is more humorous.

Liu Shengyu wrote down his doubts in his diary:

"So the special breathing technique I learned from that charcoal-selling boy is actually the lost art of Sun Breathing?"

"And that guy who suddenly turned and ran away after seeing the Yoriichi Zero I created, was the Demon King, Kibutsuji Muzan?"

Is this reasonable?

"I'm just an ordinary blacksmith..."

Suibian! A young man with a very casual name, living a casual life. Then, he was casually killed by a flower pot, and thus entered the world of Demon Slayer! He became Tokito Muichiro's older brother, Tokito Ichiro! From then on, his life began to be more than casual...

Traveling through the world of Demon Slayer, Shigure opens the role-playing system of the universe.

The higher the missions completed and the degree of character restoration, the stronger the power gained.

The first task required at the beginning is Bai'e.

"? Bai'e beats Wuzhan? Doesn't having hands do that?"

"Nanook... uh no, Muzan Kibutsuji, I bring destruction upon you!"

Muzan Kibutsuji: "No red blade? No markings? Are you also a pillar?"

Shigure: "Pillar?... Pillars are considered pillars."...

Muzan Kibutsuji: "It's useless. Unless I wait until the sun rises, I can be resurrected even if only a piece of flesh is left..."

"I am"

"?"

"The blazing sun will eventually rise!"

Ever since the Breathing of Fire was developed during the Warring States Period, more than 80% of the Flame Pillars have carried the name of Purgatory.

Even Rengoku Kyojuro, the last Flame Pillar of the Taisho period, gave up his own dawn for the dawn of others.

But if history diverges,

That one,

It keeps growing upwards,

The flower called "Purgatory"

Inadvertently, a fruit was born, but it was helplessly abandoned. Who can guarantee that it will sprout again as a seed in the shade and grow in a deformed form...

Or will it just be a fallen petal, transforming into nutrients to dedicate itself to the growth of future generations...

(I write simply because I feel like writing. My writing may not be good, and the updates may not be on time. After all, I am also a quasi-working person.)

"Hey? System! What do you mean Nohara Shinnosuke is a Pillar? What do you mean Uchiha Sasuke is a Pillar? What do you mean the Pillar Men and Hashirama are Pillars? Tailed Beast Jinchuriki? Josuke Higashikata can do that too?!" Lu Li unexpectedly transmigrated into "Demon Slayer" and awakened the Demon Slayer "Pillar" Summoning System! Every three days, Lu Li can randomly draw a "Pillar" and gain all of their abilities. Just as he was excitedly preparing to open the system and use the Pillars' abilities to fight Muzan, Lu Li discovered that the "Pillar" drawn by the system seemed a little different from what he expected. "Hey! System! I can tolerate the previous ones! But system, what the hell is this Optimus Pillar you summoned? Kibutsuji Muzan, huh?! Kokushibo, huh?! Tell my luck!" ...Tentative protagonist's alternate worlds: "Demon Slayer," "Fate/Zero," ...
