Yang Shou transmigrated to the Dou Qi Continent and joined the Qingmu Sect.

He thought he would rise to power and become emperor, but he turned out to be mediocre and made no progress for fifteen years.

By chance, he awakened the ability to upgrade everything.

[Ding! The Qi Gathering Pill has been upgraded to a Three-Pattern Azure Spirit Pill]

[Ding! The spirit beast fire has been upgraded to Yin-Yang dual flames]

[Ding! Ordinary aptitude upgraded to peerless genius]

......

From the Dou Qi Continent to the vast world, may the Emperor live forever.

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...

Tokyo Metropolitan Advanced Nurturing High School, a closed three-year high school. Homeless transmigrator Kamio Tatsuya just wants to spend his last three years here peacefully before adulthood, just to turn 18. But why is it that even this simple wish is constantly being thwarted? Reluctantly, for the sake of a peaceful life, he has no choice but to take matters into his own hands. Sakayanagi Arisu: He's amazing. I heard his parents are gone. I wonder if he'd be willing to change his surname to Sakayanagi. Ichinose Honami: Despite my best efforts, I can't defeat him. Ryuen Sho: I love his style of doing things. Having him as a teammate was definitely the right decision. Horikita Suzune: I was here first…

Jiang Yi transmigrated to the Douluo Continent, but his martial soul was still the most useless Blue Silver Grass, with no soul power whatsoever. What should he do? Although the Sun Moon Empire hadn't yet launched a war, and the Douluo Continent was at peace, everything was relatively calm. However, even without war, survival was still extremely difficult for a commoner without soul power. Just as Jiang Yi was worrying about his future, the customized achievement system awakened. "Host awakens Blue Silver Grass martial soul. Congratulations, host, you have obtained the achievement: Jiang Yi's Blue Silver Grass. Achievement reward: 0.1 level soul power." "Soul power didn't increase for a year. Achievement: Eternal Blue Silver Grass. Reward: Blue Silver Grass shows slight evolution." "Spending 5 years to break through to level 10. Achievement: The most stable soul master in history. Reward..." With these customized achievements, Jiang Yi gradually changed...

Bai Chen, having just traveled through time, hadn't figured out what was happening when Siegfried usurped his throne. Expecting to bring shame upon the other traveler, Bai Chen suddenly heard a voice. "Chat invites you to join, yes or no?" "I'm dying, why are you here just now?" Huh? There's also a lottery feature? ... Tokisaki Kurumi: "I'm not allowed to post cards here. Thank you for your cooperation!" Bai Chen: "I just got this, newbie. Does it work?" Misaka Mikoto: "Damn you, stinking seal! I told you not to post your face!" Esdeath: "Seals don't matter, Bai Chen, will you be my boyfriend?" Bai Chen: "Huh?! Do I have a bright smile?" Makima: "Bai Chen, will you be my mistress?" Esdeath: "?" Matou Sakura: "Big brother is mine!" Shinobu Kocho: "Bai Chen-kun, you promised me you would take on the Demon King!"...

Transmigrating into Douluo Continent, awakening the Book of Destiny martial soul, he carries his fate with the book and writes his destiny with the pen. By rewriting the protagonist's fate and shifting the world line, he can increase his soul power and ascend to godhood. Mo Xianyu wields his brush, starting by writing the Rebellious Disciple System for Tang San. "Teacher, if I just add some laxatives to Luo Sanpao's radish, my Blue Silver Grass can evolve into the Blue Silver King. You won't blame me, right?" From then on, having tasted the sweetness, Tang San triumphed, acquiring a new famous saying—"In this world, the accomplished are my teachers; everyone can be my teacher, even those who aren't human."... Later, the Azure Bull Python bowed its head to the ruler of soul beasts; war and peace crowned the Empress of Star Luo; wealth...

My name is Shuo Ye Qianxuan. I transmigrated into Naruto and became Konoha's famous "super repeat student".

But don't panic, I have a system!

"System, draw a prize!"

[Ding! Congratulations, host, you have acquired the rare skill—[Recovery]!]

[Skill Description: Can restore the target to their optimal state before injury!]

[Special Effect 1: During treatment, you will simultaneously experience all of the other person's pain and memories.]

[Special Effect 2: When healing others, there is a chance to copy one of their talents or abilities!]

I'm dumbfounded. This side effect... is it trying to make me experience the agony of dying with all eight gates open?

Until that day, I used [Reply] to save a dying Uchiha clansman.

[Ding! Talent copied successfully! Congratulations, host, you have obtained the bloodline limit—Sharingan!]

I understand!

Experiencing pain is nothing! This is practically a VIP passage to the pinnacle of the ninja world!

Heal Tsunade → Copy [Sage Body]!

Heal Minato → Copy [Flying Thunder God Talent]!

Giving it to Orochimaru... never mind, that's a bit perverted.

In the 37th year of Konoha, the Second Ninja World War had already broken out.

This year, the pseudo-spinner graduated from the Ninja Academy. The leader of the team was Orochimaru, who had just been awarded the title of "Three Ninjas". His teammate was his younger brother Nawaki, who only lived in Tsunade's memories... and there was also the insignificant "Insect Playing Family" Aburame Shiwei.

This year.

The protagonist Uzumaki Naruto was not born yet, the future Fourth Hokage Minato Namikaze was just a civilian genius in a ninja school, and Uzumaki Kushina had not yet become the Nine-Tails Jinchuriki.

But the pseudo-spinner who possessed a bond system allowed the ninja world to witness the power of bonds in advance.

You know the Five Elements Ninjutsu! You know the Space-Time Ninjutsu! You know special secret techniques! You have a special bloodline and possess a special bloodline limit!

Then you are all my wings!!!

The Rock Ninja, the Mist Ninja, the Lightning Ninja, and the Sand Ninja wailed in pain: "How come he knows everything???"

Pseudo-spinner: "This is our bond!!!"

......

Danzo: "Tripping man, you'll regret it!"

Kizuna: "Danzo, I am the Hokage!"

......

Hatake Kakashi: "Why is your snow dog also called Kakashi?"

Tanren: "When it comes to names, whoever comes up with it first gets it."

Kakashi: "Ahhhh!"

What kind of collision would occur in the Naruto world if someone obtained a Fruit of Ope Ope no Shit (without the weakness to seawater), a fruit that consumes stamina, and a Saiyan-like physique?

My name is Bai Xing. I was playing a game and I was transported to another world. Luckily, I was able to travel back, and I even activated a magical system.

Main quest: Survive until the final chapters of Shippuden.

award:

First, he could choose to stay in the present world and obtain a noble black card containing a billion dollars in legal and compliant liquid funds;

Secondly, he can obtain the character's peak strength and travel to other worlds he wishes to go to, or stay in this Naruto world to continue living.

For a modern person, neither choice would be a loss, but for someone who has spent half a month and three years in the "Second World," only one option remains:

—I need to find another world, I need to make a quick getaway!
