Transmigrating into Harry Potter, he gains a system that allows him to grow stronger through learning. While young wizards are still struggling with the Levitation Charm, Rock has already mastered the entire Standard Spellbook. Hermione: "His notes are more complete than Mrs. Pince's!" The Weasley twins: "Great Rock! We call you the strongest!" Snape: "Potter! If your potions were even a tenth as good as his..." [Flicker] is maxed out to the Law level, a single [Radiant] Holy Light will crush any dissent. [Levitation] is maxed out to the Myth level, a wave of the hand [Universal Pull] will hold the stars in his palm. When Voldemort brandishes the Elder Wand, announcing his 'Return of the Dead', Rock looks at the densely packed, dazzlingly bright max-level skill panel and silently pulls out the wand he's swung countless times. "Tom, have you ever heard of a spell that falls from the sky... Expelliarmus?"...

“As I said, although I am from the Heaven-Defying Sect, I am essentially a person who adheres to traditional cultivation methods. I am not a heaven-defying god.”

"What? You're saying I practice swordsmanship every day without learning any magic or cultivation techniques? How can I become a strong person? Are you cheating?"

"Nonsense. It's all because I want to get closer to ordinary people. Don't talk about cheating or hacking. I'm not that kind of person."

Just then, a fierce shout comes from behind: "Let go of that girl!" "Ding! Master is about to face Tatsumaki's pursuit. Please choose!" "Option 1: Throw Rem at me!

He transmigrated into the world of One Piece. At the start, at the invitation of Pirate King Luffy, Rein joined the *Hat Pirates*. However, because he learned from his mistakes and constantly finished off weakened enemies, he clashed with the overly compassionate members of the *Hat Pirates*. In a fit of anger, he quit the *Hat Pirates*. As a half-Lunaria, he unintentionally gained the power of the Ox-Ox Fruit, a Mythical Zoan type, in its Kirin form. Rein then joined the Beasts Pirates, becoming Kaido's son-in-law and Yamato's fiancé. Before the Marineford War, when *Hat Luffy* pleaded for help, he coldly refused. "Sorry, I don't want to play house with you guys anymore!" "From now on, please call me the Fourth Calamity of the Beasts Pirates—Blood Prison Rein!" "Father-in-law, you've been on the throne of the strongest creature on land, sea, and air for too long; it's time to step down!" "I declare that from today onwards… the new Beasts Pirates will be entirely composed of Mythical Zoan types!"

Time travel isn't about fighting and killing; it's about navigating human relationships and social interactions. In the morning, head to Kiku-no-Oro, then take Sylveon to Reverse Mt. for some sightseeing; at noon, go to Totsuki Cu Chulainn, then attend a Muse concert with Erina; at night, camp by the river, snuggling in Arcanine's arms watching magical girls fight. In short… send those who say Dark Souls in the morning, Warhammer Games at noon, and Containment in the evening to Siberia to dig potatoes!

She unexpectedly transmigrated to the Douluo Continent and became a newborn, only to be abandoned in the wild by her biological parents.

Fortunately, a patrol of soldiers from the Spirit Hall passed by, and a couple in the patrol adopted the baby and named him Dongfang Jing.

Three years later, the couple had a daughter named Dongfang Yao.

However, one day, their parents suddenly passed away, and from then on, the brother and sister depended on each other for survival.

He was her support, the light that the young girl longed for most.

She was his little sun, the only warm sun in the boy's cold world.

...

At the age of six, Dongfang Jing awakened his martial soul Shattered Mirror and innate full soul power, and at the same time, a 'mirror image' identical to him was born.

In order to gain the power to protect his younger sister, the boy repeatedly broke with convention and cultivated the Shattered Mirror Martial Soul to its peak.

From then on, in the world of Soul Masters, whenever that silver-haired boy was mentioned, everyone would turn pale with fear.

______

Dai Mubai: "Impossible! He's the same age as me, so why is his soul power so much higher than mine?!"

Ma Hongjun: "Ugh~ My Demon Orb!!! It was hundreds of meters away from me, how did it manage to attack me?"

Tang San: "I can't tell, I really can't tell! Which one is his true form?"

Master: "My theory is infallible! This must be an illusion, hahahahaha!"

Qian Renxue: "Such a genius must be put to my use!"

Tang Hao: "You hindered the growth of the mistress, so I must kill her... Hmm? How did Ah Yin end up in your hands?"

Dongfang Yao: "Brother is mighty! (??????)?"

(The story involves a lot of abuse of the three main characters and the main character, but it doesn't involve forcibly vilifying any factions or having the main character join a sect. However, there will be some plot development.)

Lin Yu transmigrated to the world of Demon Slayer. Awakening the Character Inheritance System, he immediately inherited the legacy of the blind swordsman, Fujitora Issho. Thus, a swordsman of unparalleled skill and mastery was born… “This swordsmanship!” “Is this really a sword that a human could wield?!” Kibutsuji Muzan collapsed to the ground, his face filled with unprecedented terror. Kibutsuji Muzan once again experienced the terror of being dominated by that figure four hundred years ago, even more terrifying than before. “This oppressive feeling…” “Perhaps, compared to us, you are the monster.” Upper Moon One, Kokushibo, stared intently at the man standing before him. Having experienced the terror of that man four hundred years ago, Kokushibo could better understand the terror of the man before him.
