After accidentally traveling to the world of Devouring the Stars, Lu Qingshan thought he could become a powerful being, but he never expected that after ninety thousand years he was still only at the ninth level of the universe.

Just when the deadline was approaching and he was waiting for death, he suddenly discovered that he had awakened the golden finger.

All you need to do is find a genius, take him as your apprentice, and bestow treasures upon him, and you can get a return of up to ten thousand times.

Give the disciple the Nine-Leaf Spiritual Ginseng and return the Fruit of Life.

He bestowed upon his disciple the immortal divine weapon, the Cloak Hammer, and returned the precious Thousand-pound Staff.

Give the disciples the space crystal and return the heart of space.

…

From then on, the original universe had a strongest mentor, and the universe had a supreme teacher.

Don’t ask me why all my disciples have become successful?

As long as you are willing, you can do it.

[It doesn't start on Earth, doesn't follow the Genius Battle route, doesn't steal the protagonist's opportunity, and the timeline is before Luo Feng appears.]

When Tanjiro Kamado stepped into Nada Spider Mountain, a huge screen appeared in the sky.

The question-and-answer system has officially started. As long as you answer the questions, you can get various rewards, including but not limited to "resurrection", "turning back into a human", "blue red spider lily", etc., to solve your unsatisfactory wishes!

After resurrecting his wife, Akaza said: "I am Fist Pillar. Muzan, I will *your Sage!"

Shinobu Kocho: "I have a gentle personality? Wait until I get the reward and you will know what a killing angel is [sinister smile]."

Agatsuma Zenitsu: "Grandpa was forced to commit suicide? I'll show you what a fucking thunder pillar is! What a fucking thunder pillar is!"

Douma: "The punishment is to experience extreme pain? There's such a good thing?!"

Mitsuri Kanroji: "Eh?! Mr. Iguro likes me? Then I'll confess right now!!!"

Kokushibo: "I want to resurrect Yunichi. Even if Muzan comes, he can't stop me. I said it!"; Muzan: "You are really my living father."

Tomioka Giyu: "I want to be the most popular person [cold face]."

Muzan Kibutsuji: "The reward is a blue Higanbana?! As long as I can get it, I'll do anything~"

......

Is the plot difficult to accept?

Through questions and answers, all of them were changed to perfect endings!

(cp: After chapter 20, I will not promote the official version, only Komare and Snakereen)

Si Jinkun, who traveled to the Demon Slayer world, shouted at the beginning: I don’t want to be a human being anymore!

He went completely crazy after arriving in the world of Demon Slayer

That shadow that has lingered for a thousand years—Muzan Kibutsuji! That pitiful creature who cowers in fear because of the curse, that false king who vainly seeks immortality!

All his struggles and blood ghost arts became futile jokes in front of Si Jinkun's ultimate body that combined the curse of the stone ghost face and the essence of countless ghosts!

He treats Wuzan as a high-end bun

It also forced the demons and the Demon Slayer Corps to join forces for the only time in a hundred years.

Many years later, Si Jinkun, who had already become a JO-level creature, looked at the world he had ruined and fell into deep thought.

My name is Su Wuji, and it has been 22 years since I traveled to a world where demons have revived.

I thought I could live a peaceful life, but I found out that everyone in this world is mentally ill!

The demon who ate people was killed by me with one sword, but there are still people shouting "The demon's life is also a life"?

I'll slap you twice on the spot!

After joining the Demon Slayer Division, I became the most feared "Demon Smasher" in Jiangcheng.

A Nightcry demon is parasitizing villagers? Clear the screen with one strike!

The vampires are pretending to coexist peacefully? Just smack their mouths against the wall!

Rape and sell plasma? Cut off the power and punish with a baton!

I don’t care about the powerful, public opinion, or that bullshit “Demon Rights Protection Act.”

Demons should die!

Can't kill them all? Then kill them until they are extinct!

"Success doesn't have to be mine?"

Oh, success will definitely be mine!

(Invincible flow + decisive killing + violent face slapping, high energy throughout without boring moments, specially designed to deal with saintly bitches and demon lickers!)
