In the worlds of Naruto, One Piece, Bleach, Demon Slayer, and One-Punch Man, what kind of effects would Link have if he combined chakra with breathing techniques, Haki with limiters, and spiritual pressure with genjutsu?

Brief introduction - just take a look

A cultivator accidentally enters a crossover anime world and embarks on a journey into the God's Space (not the original). (Multiple female leads, including Yukinoshita, Ryo Yamada, Ryougi Shiki, and Ai Hayasaka)

Mission worlds (Fate, Akame ga Kill!, Naruto...)

(I didn't get the pacing right. There will be a lot of Yukino's scenes at the beginning, so I can only finish it with Akame ga Kill! I'll revise it later.)

Su Ye, who transmigrated to the world of Hunter x Hunter, awakened the Nen ability to materialize the ultimate attacks of anime characters. Netero: "I used to think the Hundred-Style Guanyin was the strongest. But when a Thousand-Armed Buddha hundreds of meters tall appeared before me, I realized what insignificance truly meant." Chimera Ant King: "I was born with the goal of ruling the world, but why was I killed by a mere human with a single punch?" Looking at the Chimera Ant King, whom he had pulverized with a single punch, Su Ye turned to the stunned protagonist group and smiled brightly, "From now on, please call me One-Punch Man!"

[Empire-style, summoning-style, decisive in killing, abundant rewards!]

Xu Nian'an transmigrates to Douluo Continent and becomes the prince of the Tianxing Kingdom.

[Awaken the Supreme Empire System!]

[Starting with the Guardian Sect (Holy Spirit Cult), the Hand of the Nation (Long Xiaoyao), and the Dragon Emperor Sword, the Martial Soul of National Fortune!]

The Tianxing Kingdom is in a critical situation; its king has been unexpectedly assassinated.

Domestically, a rebellious party holds power, displaced people and bandits are rampant, and abroad, two major empires and ten kingdoms are eyeing the kingdom covetously, wanting to divide it up.

Just as Xu Nian'an was in despair after the cataclysmic start, the system awakened.

[Supreme Empire System!]

[Congratulations, host, on obtaining the Holy Spirit Cult of the Guardian God!]

[Congratulations, host, on obtaining the Guardian Hand, Long Xiaoyao!]

[Ding! Congratulations, host, you have obtained the National Fortune Martial Soul, the Emperor Sword!]

····

The Kingdom of Gulei is pressuring me, and the Kingdom of Benlang is joining in the fun too, so let's fight!

The evil spirit masters appeared ten thousand years ahead of schedule, turning the battlefield into a living hell. To quell the turmoil, we must rise to the occasion, reclaim lost territory, and forge an unparalleled empire, starting with me!

In his past life, Ji Yuan was a civil engineering intern; in this life, he is a menial laborer in the Gu Sect. Reincarnated, Ji Yuan spent nine years gathering Qi in the Gu Sect, and upon achieving Qi refinement, he accidentally obtained a piece of white jade tortoise shell. This shell could bring good fortune and avert misfortune, and its divination could predict the future. [Very unlucky divination: ...Foundation Establishment opportunity, but virtue does not match position; immediate execution, extremely unlucky.] Ji Yuan played it safe, not taking the Foundation Establishment opportunity, which was seized by the menial laborer Cui Hao. The neighboring True Person Huang Ting calculated with his fingers: "Disciple, you have a Foundation Establishment opportunity." Cui Hao refined the stone, and the opportunity vanished. True Person Huang Ting was furious, refining Cui Hao instantly, and smiled, "Disciple, your Foundation Establishment opportunity is still 98% complete." He left the Menial Laborer's Fifth Division and entered the River Digging Civil Engineering Peak. [Above-Middle Divination: Heading to the River Digging...Foundation Establishment opportunity, no worries, auspicious.] [Middle-Middle Divination: River Digging Supervisor...Qi Refining opportunity, attracting jealousy from cultivators, neutral.] [Below-Middle Divination: Entrusted...]

After his death, Xia Mu arrived in the afterlife.

When I opened my eyes, all I saw was a vast desert, with a pale moon hanging in the sky.

Then, another all-white monster attacked him.

Just when Xia Mu thought he was going to die, a figure dressed in black and wielding a long sword appeared and dealt with the monster.

Everything is moving in a positive direction.

Unexpectedly, an even bigger monster appeared, and before he could even ask the man who saved him his name, the man died.

In order to survive, Xia Mu had no choice but to pick up the long sword left behind by the man and fight.

He didn't know that the moment he grasped that knife, he had become Death himself!

...

From Hueco Mundo to Soul Society, from the Expeditionary Force to the Gotei 13.

This is Natsuki's life as a Grim Reaper!

(Note: Hueco Mundo is just the initial spawn point and won't last long; you'll soon enter Soul Society.)

(Note 2: The protagonist has only watched the anime, so he only knows the plot that appeared in the anime and the original TV series plots, and does not know the plot of the official novels, etc.)

A soul transmigrates into a martial arts world; a top-notch private investigator in his past life, he is reborn as a lowly constable in this life.

The detective system is activated at the start, and the newbie gift pack is actually the "Sunflower Manual"?

To practice this skill, one must first castrate oneself?

To hell with it! I'll practice this divine skill against the odds and forge a path of unparalleled yang energy, unlike anything I've ever seen before!

Others cultivate themselves through enlightenment, I become stronger by solving cases!

From then on, the imperial court gained a madman, and the martial arts world gained a taboo.

The Empress regarded me as the sharpest knife and ordered me to stir up trouble in the capital.

The Marquis of Zhenyuan hates me to the bone and has vowed to grind me to dust.

The group of "mentally ill" teammates of the Sky Patrol Mirror are even more unreliable than the last!

The justice that the law cannot provide, I will provide!

I will kill the wicked who the law cannot kill!

My name is Chen Shisan.

I am irreconcilably opposed to evil!

Having been transported to the world of The Legend of Heroes: Trails of Cold Steel, starting as a lowly Bracer, what kind of waves will this protagonist, who is familiar with the story of The Legend of Heroes, stir up in this world?

Original title: [High Martial Arts: Gaining a Little Health Per Second, Sweeping Across the Heavens], a novel about the competition for supremacy among the geniuses of all races! The number one exhilarating novel in the universe, igniting the starry sky!

The ability to become stronger just by breathing is too overpowered!

Su Jie transmigrated into the body of the ultimate simp in a martial arts world, his original body's life force drained by the class beauty. In this desperate situation, the [Strongest Martial Arts System of All Heavens] activated, rewarding him with a supreme-level breathing technique—automatically increasing his life force by 1 point per second!

While others toiled for a day, he breathed for a second. In just over ten minutes, his martial arts skills reached perfection; overnight, his combat power exceeded one hundred.

"Martial Aperture Tempering is a gold-devouring beast?" Su Jie laughed as he looked at the vast amount of Qi and Blood that was increasing wildly every second and never stopping in the system.

His goal is something no one in mythology can achieve—ninety-nine apertures, ten levels of perfection, to forge an unparalleled foundation for the Dao!

[Martial Aperture] [Martial Vein] [Martial Bone] [Martial Soul] [Battle Body] [Divine Treasure] [Dharma Image] [Dharma Ring] [Supreme Law], damn system, max out all of them!

This is a path of crushing dominance unique to the overpowered. With unparalleled might, they sweep across the heavens!

The heavens are revived because of me, and all worlds are subject to my calamity. My name is your destiny!

[Snake Aunt + Thrilling Read + Gu Refining + Multiple Female Leads + Ghostly Spirits]

Transmigrating into the Naruto world, Uchiha Kogetsu, with the help of the memories inherited by the ghost, created the Yin-Yang Reincarnation Gu, using Orochimaru as a safeguard in the early stages!

Comforting the injured Naruto, adopting the homeless Sasuke, and gently pushing forward the hidden demon from beyond the heavens, the Fourth Shinobi World War begins just like in the original story.

When Madara Uchiha became the Six Paths, and the whole world was plunged into darkness, Naruto and Sasuke activated Six Paths Mode!

An arm suddenly pierced through the bodies of the two people, and Uchiha Kogetsu looked calmly at Six Paths Madara!

"I have always been a madman and a fanatic, questioning Yin and Yang and the universe with my bare hands. I have been planning and accumulating for decades, waiting for this day to achieve eternal life!"

After Gu Yue finished speaking, he no longer concealed his aura, and it was indeed the cultivation of the Six Paths. In an instant, he was about to refine Ming and Zuo.

"Success! The Self-Respecting Immortal Embryo Gu!"

Lots of girls! Lots of girls! Brothers!
