"In the 42nd year of the Shenwu reign, a flying dragon, a hundred feet long, crossed the Jinghu Lake. Heavy rain lasted for nine days, causing the dike to burst, and the city was submerged. Over a million people died, and all of them grew scales and horns."

In times of chaos and demons, people's lives are as cheap as grass.

Jiang Lan traveled to the Demon Suppression Division and became a servant.

Fortunately, the system of having many children and more blessings has been awakened.

As long as you marry, consummate the marriage, and have children, you can become stronger.

Not only that, the cultivation of his offspring can also provide feedback to Jiang Lan himself.

[Host successfully marries, and obtains: Marrow Cleansing Pill, Realm Breaking Pill. Traits: Yin and Yang Interaction, Dragon Tendons and Dragon Bones. Martial Arts: Chasing Clouds on Waves]

The host's wife successfully gave birth to a son. Gained: Divine Yuan Dan, Heavenly Fragrance Life-Sustaining Dew. Traits: Burning Heart and Burning Bones, Black Scale Armor. Martial Arts: Remnant Rainbow Drinking Moon.

…

Millions of years later, Jiang Lan stood at the top of the world, and wherever his eyes went, gods and demons surrendered!

You can become stronger by spending money.

Su Ying, who died accidentally, traveled to a world full of demons and evil spirits.

As long as you kill a living being, you can absorb its lifespan and deduce the martial arts infinitely.

A few years later...

The human race actually joined forces with the demons and evil spirits, pointing at Su Ying and cursing: "He's going crazy with killing! Who will control this killer god?"

The Jiuzhou Continent contains an era of chaos and fiendish demons, haunted by mysterious beings and fraught with feuding martial families, demonic sacred grounds, and endless struggles between various powers. Conflict is a constant throughout the world.

Within such darkness, Gu Chen opened his eyes to this reality.

At the same time, he discovered that as long as he slew these fiendish demons and ghosts, his cultivation strength could continually elevate.

Killing a Panic Level Demon yields a decade's worth of cultivation.

Slaying a Ghost Level Fiendish Ghost brings thirty years of cultivation.

...

Eventually, one day, staring at the endless swarm of fiendish demons and world-renowned grandmasters in his path, Gu Chen chuckled lightly, "Are you able to withstand this fist of mine, charged with 1600 years of cultivation?"

After staying up all night to finish reading the entire series of Pillar Slayer, Qin Zi suddenly fainted from anger.

When he woke up again, he found that he had actually transmigrated into this manga and become the Water Pillar "Giyu Tomioka"!

This time, he will do everything he can to save everyone in the Demon Slayer Corps, find a way to break the curse of the Demon Slayer Mark, and prevent the tragedy from happening again!

"Although it's a transmigration into a book, his personality and consciousness will lean more towards Giyu Tomioka. Or rather, he is Giyu Tomioka, and Giyu Tomioka is also him."

"Of course, this time our Giyu won't be disliked, probably~"

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.

The countries are in chaos, monsters are causing trouble

Warlords are everywhere, people are living

in misery Qi Xiu traveled through the troubled times, a scholar, and accidentally gained the ability of "paying what you pay for".

The most common abilities, as long as the level is upgraded, will be endowed with magical powers!

Ordinary [calligraphy] = [Xiantian Yunzhuan] that suppresses the heavens with words .

Complex and difficult [alchemy] = [Creation Magic] that can easily make pills

. There are also those third-rate [martial arts] that are looked down upon by wild ways, [magic] for people's entertainment, [planting] in the fields

...

After several years.

Overwhelmed the monsters and suppressed the demons.

Qi Xiu gathered his sleeves and smiled modestly:

"Qi has no talent, but he is just diligent on weekdays"

...

Let's take a look at the Demon Slayer fanfiction

Ashina, the land of reeds, half-knelt on the ground, looking at Kuro who was unconscious in front of him.

......

"Please live on as a human being."

He swung the immortal sword "Bai Lei" on his neck, and the blood that should have splashed out turned into flying cherry blossoms floating on the reeds.

——————

During the Taisho period, in the alleys of a remote town, a lifeless body glowed with a pink divine light.

"resurrection"

A lifeless, thin figure sat up from the rain.

"Where is this..."

At this point, the Son of God and his Ninja Wolf, although in two different worlds, are both reborn at this moment!

Tiandao Feiyuzhen, accidentally reincarnated into the world of Demon Slayer, was picked up and raised by the former Naruto Pillar. He vowed to change the regrets of the Pillar Slayer, and since then...

There is a new pair of master and disciple on Taoshan, who are enemies and have a kind master and filial disciple.

The Demon Slayer Corps now has a thick-skinned and strongest pillar.

Shinobu Kocho has a sweetheart she cares about.

Muzan has a new big father - another psychological shadow after Yoriichi.

When the evil spirits are slain, the night will no longer be scary!

Ghosts and monsters in the darkness spy on the human world.

In unseen corners, bloodshed and cruelty quietly grow. Ghosts eat men, men slay ghosts—millennial legends and grudges are intertwined with fate...

To end the curse that had plagued his family for millennia, he chose the darkest path.

As the 97th Master of the Demon Slayer Corps, Kagaya Ubuyashiki has always been a gentle and revered leader in the hearts of all his members. However, as the curse increasingly erodes his life, and as he foresees that his daughters will repeat the same mistakes, on the verge of despair, he makes a choice that will shake the world—to make a deal with Muzan Kibutsuji and become the most hidden Upper Moon Zero.

By day, he remains the lord who guides everyone in the fight against demons; by night, however, he is loyal to his millennia-old nemesis. When the truth is revealed on the eve of the final battle, the Demon Slayer Corps' faith crumbles overnight. The former "father" becomes the most despicable traitor, and the Pillars who once swore their undying loyalty turn their blades against each other.

But at the end of this sin-soaked road, does Kagaya hold a trump card that can turn the tide for a thousand years? When wisteria blossoms alongside bloodshed, this game of chess that began with betrayal will finally reach a shocking conclusion.
