If one can attain immortality, why bother about cultivating immortality or demonic cultivation?

On the path to immortality, I will kill gods and demons who stand in my way. What does the so-called irreconcilable conflict between the Dao and the demons have to do with me?

Those who obey me are righteous, those who oppose me are evil!

The main world is immortal, and the dungeons are, in order, Demi-Gods and Semi-Devils, A Record of a Mortal's Journey to Immortality, Shrouding the Heavens, Yang Shen...

Levi accidentally traveled to countless worlds, and together with the Levis of countless worlds, he established a cross-dimensional technological alliance.

A bunch of stupid teammates, I don’t want you to kill my naive brother.

Jiang Chen traveled through time accidentally and began his journey in anime.

The world is tentatively determined to be: Naruto - Attack on Titan - Demon Slayer - Sword Art Online - Detective Conan, etc.

————

In the Naruto world, Jiang Chen obtained a system that gives him a 10,000-fold return on his disciples. As long as he teaches his disciples, he can get corresponding high-fold return rewards.

As a reward, Jiang Chen taught Hinata the black coffin of the ghost way that he brought from the world of death.

During the Chunin Exam,

Neji: "Give up, Hinata, you are not fit to be a ninja."

Hinata: "I don't want to run away anymore, Neji-nii, let's have a showdown! A faintly turbid emblem reveals an unruly and arrogant talent...Hadō no 90: Black Coffin!!!"

Everyone: "She calls me brother, but she kills me. This girl is so scary!"

(The introduction is weak, please move to the main text~)

Transmigrating to the Naruto world, not only did he become Uzumaki Naruto, he also possessed the power of fusion. The fusion of two chakras with different properties is called a bloodline limit, three is called a bloodline elimination, but what about four? Five? What about Yin-Yang Release and natural energy? Kaguya Ōtsutsuki, and the enemy hiding behind her...

All Naruto wanted to say was, "Five words floating in the sky are nothing."

It is just a fantastic imagining based on the original work, no system, no magic, no cultivation...

Preparing for the world of *Dragon Maid*, *The King of Fighters*, *Double Dragon*, *Naruto*, *One-Punch Man*, *Marvel*, *DC*, etc.

Time Travel, but there is no system and no old man. Just when the various Fengya struggled for many years and finally accepted the reality helplessly, things took a turn for the better. They came to a mysterious space. There, he saw himself from all realms. They could receive each other's memories, and share power and talents! But there seemed to be a little problem with this turn of events. Haruno Sakura, Rukia, Hermione... all of them gritted their teeth and clenched their fists: "Why are they all female characters!" (All female protagonists, very imaginative, not following the original routine.)

[Puella Magi Madoka Magica + MyGO/Ave Mujica + Sho ALL] People call growing women "girls," so you, who will eventually be called "witches," should be called "magical girls." For some reason, Shoko Toyokawa is on the verge of becoming a witch. To avoid dragging down her teammates, she's quitting Crychic. But why did Tomo chase her? She affectionately calls out, "I want to be Sho's heart-shaped box." Mikado Hatsuka, her childhood sweetheart, whom she hadn't seen in years, takes her home. Information dealer Wakami Yutenji cries and cries, hugging her legs, declaring, "I'll do anything." Super mercenary Hachiman Kairin makes a lifelong pact with herself. And Wakaba Mutsu, who's more like a sister than a sister, made the unforgettable wish upon becoming a magical girl: "I want to always be by Sho's side." When did so many troublesome people appear around me? And, Yuki, why did you put your scythe on my neck? What is Witch Nirvana?
