[System pays for life][Exhilarating combat][Thunderous][Growth]

When Yasui Ryosuke is transported to the world of Demon Slayer, he is devastated.

Good news: He is familiar with the original work and knows the plot.

Bad news: The original owner was a sickly person who was not long for life, and the only cheat was the double-dealing system that required spending a lot of time and effort to become stronger!

"You mean killing demons grants you lifespan, which can then be used to enhance your breathing technique and sword skills?"

Yes, that's right~

How much longer can I live?

[Congenital liver failure, at most one year, haha~]

"Fuck your sister!"

Yasui Ryojie was angry.

What kind of good system would make a cancer-stricken host risk their life?

Knowing the original plot, Ryosuke would never willingly seek his own death by joining the scoundrel Muzan.

If that's the case, then kill!

Kill them until the sky darkens...

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," ...

Su Chen traveled through Demon Slayer's Spider Mountain and almost got killed as he landed.

At the critical moment, he awakens the golden finger and has an incredible understanding.

In the end, he was injured and rescued by Shinobu Kocho and became a member of the "Butterfly House".

Su Chen goes out with Shinobu Kocho to rescue people during the day, and secretly kills ghosts at night to make money to support the girls in the Butterfly House.

While walking, constantly use the golden finger to observe and learn.

[You observed Shinobu Kocho's healing process and gained something from it. You created your own skill: Supreme Poisonous Healing!]

[You observed Kanao's sword training and suddenly an idea struck you, revealing a unique sword technique. A thought blossomed!]

You spied on the former Sound Pillar's thunder cry, gathering mosquitoes into thunder. Deeply impressed, you modified it slightly and developed the Lightning Release - Chidori Style!

From then on, Butterfly House had a famous and evil male doctor.

When everyone asked Su Chen why he worked so hard, Su Chen's thoughts were very simple.

"Why kill ghosts? Of course, it's to keep the flowers in the Butterfly House working well and feeding them!"

Kotoji Mirai transmigrated to Soul Society and became a carefree, lazy bum in the 9th Division. Unfortunately, his salary wasn't enough for drinking, so he resorted to writing novels for the *Seireitei Newsletter* to earn extra money. His first novel, *The Arrogance and Loneliness of a Prodigy*, featured the protagonist "Aikawa." The next day, a junior named Aizen Sosuke, with a gentle smile, came to ask him about the profound meaning of the "Throne of the Sky." His second novel, *The Murderer of Meteor City*, featured the protagonist "Shuka." That night, the gentlest captain of the 4th Division, Unohana, sat in his room with a sword, smiling as she asked him: "What is the meaning of 'the loneliness of a mad beauty'?" Kotoji Mirai was now panicking, currently writing *The Invisible Empire Hidden in Soul Society*. Would he end up killing off his own people? Kotoji Mirai discovered that, without realizing it, he had acquired the title of "The Most Beautiful Nobleman in Soul Society." "Isn't this going to kill me?" He drew his Zanpakuto, unleashing his true name, "Zhuiwen Banshou" (meaning "All Things Under Heaven"). "The future of Soul Society will be written by me."

As the fifth prince of Daxia, Xia Taige wanted to live a peaceful and enjoyable life, but the dog system asked him to suppress the martial arts world!

[Ding! Since ancient times, heroes have used force to break the law! The people in the martial arts world have no respect for the imperial court and act recklessly. The system does not allow such a powerful existence! ! !]

[Ding! Congratulations to the host for successfully signing in to the organization - Luowang]

Adhering to the principle that if I don't offend others, others will offend me, I will start to kill them all!

[Shura Field] + [Playing with memes] + [Live] + [Seven Ex-Girlfriends] + [Relaxed and without bitterness, deep hatred]

Bai Ye traveled through a parallel world and was a top star from the start. You want me to participate in a dating show with my seven exes?

He never expected that what he thought was a situation where he had to avoid his ex-girlfriends turned out to be a feast of reunion where his ex-girlfriends extended olive branches to him one after another.

When the whole network was eating melons and crazy about CP, Bai Ye was numb.

Are you playing the peak competition of a dating variety show?! How do you play with all the ex-girlfriends?

Shirakawa Shiki traveled to the world of anime, flirting with beautiful girls in the air, and lived a comfortable life. However, why are their eyes getting more and more wrong? Yukinoshita Yukino: "Shiki-kun, which one is the real you?" Sakurajima Mai: "Let me be your only bunny girl, okay, Shiki-kun." Kasumigaoka Utaha: "I obviously met you first, why..." Kitagawa Umi: "Shiki-kun, I only wear cosplay clothes for you to see." Kato Megumi: "The personality of the senior is a bit bad, but..." Nakano Miku: "Shiki... Shiki-kun is the samurai in my mind." Makinohara Shoko: "Wu... O*chan is Shoko's, you thieving cats!" The main focus is on the daily world of anime, and other female characters will appear in the future.

Transmigrated into the body of a genius with explosive intelligence, only to discover he can switch between anime worlds. Rejecting sadness, rejecting mediocrity, he embarks on a path of unstoppable dominance!

[Intelligence system + urban slice-of-life + spy agents + multiple female leads]

Chen Yang lost his job, his father was seriously ill, and he couldn't afford surgery... He unexpectedly awakened the "Daily Intelligence System".

[Intelligence 1]: In half an hour, you will experience a car accident, resulting in the destruction of the car and your death.

[Intelligence 2]: There is an A-level wanted criminal in the neighborhood where you rent a room. The bounty is 100,000.

[Intelligence 3]: On the antique street, someone found a bargain at a low price and made a profit of 100 times.

[Intelligence 4]: The beautiful doctor is tossing and turning at night, and has developed wicked thoughts about you.

[Intelligence 5]: Evergreen Company, whose boss is a spy, poses a huge threat.

Chen Yang used intelligence—

Dating, catching spies, making money, raking in hundreds of millions.

A shadow spy from a small island nation died with his eyes wide open in disbelief.

"Impossible! I was born and raised in the Dragon Kingdom... How could you possibly see through this?"

The top assassin from India is in a panic:

"I've been hiding for three years without anyone noticing, how come I'm exposed the moment you arrive?"

A veteran special agent from the Dragon Kingdom looked helpless:

"Can't you be a little more discreet, kid?"

"You've caught all the spies and taken all the rewards, what are we going to eat?"

At a lakeside villa, a group of mermaids play and chat in the pool...

"Brother Yang, you're making money every day, you're already richer than a country, and you have so many sisters around you, don't you have any ideas?"

Chen Yang chuckled:

"Of course I have ideas... Let's keep making money!"

"However, money is hard to come by these days, so I'm planning to go out and earn some extra cash."

The beautiful King's ace spy, tears streaming down his face:

"Oh...shit!"

"You're making money, so why the hell are you messing with me???"
