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.]

Tang Ze: Detectives can only follow in the footsteps of criminals to catch them, but I can rely on knowledge to foresee the future and stop the case!

Conan: Looks like I need to go to Hawaii for retraining!

Tang Ze: Detectives often face the danger of being counter-killed by prisoners, but my physical solution can reduce casualties!

Conan: Don’t make it so high-tech to solve crimes by force! !

Tang Ze: No matter how small things are, when you notice it, you may be able to save a life!

Everyone: Do you have persecution paranoia? How did he find out that he was going to commit a crime? And it’s so accurate every time! !

Tang Ze: Uh… sorry~ I admit that I have hung up~

Flowing water has no shape, drifting wind leaves no trace, and all reasoning depends on the heart. Today's case is related to an urban legend… Legend has it that if you pray to the Hell Puppet Master at midnight, telling him your information and your deepest resentment, the Hell Puppet Master will reveal a complete criminal plan… The only one to uncover the truth is a criminology professor with the nominal title of consultant but far more power than most—Gao Yuanzhao. (I've made some appropriate modifications to the cases to ensure they're exciting, and I won't hesitate to include any female characters; you can check the related sections of the work for more information.)

Awakening to a new life, Ye Chuanxin regains his memories. He discovers he's been reincarnated into the world of Detective Conan. And it's a patchwork of Conan-esque worlds. His system is from Assassin's Creed. The artifact of the Assassin Master is from Cat's Eye. Wait, if there's Cat's Eye, then there must be Lupin III, right? Actually, there's more. Checking international news, John Wick from Continental Hotel is on Interpol's Red Notice. On the streets of Tokyo, Han from Fast & Furious is helping the Yamaguchi-gumi transport special goods in Shinjuku. In the US, Ethan Hunt of the CIA's IMF team is recruited to investigate an organization called the Knights Templar that sells nuclear waste in Saudi Arabia. In the UK, Kingsmen agents are investigating the Thousand-Faced Witch...

At a top-secret base of a Tokyo police department, Rei Furuya, Japan's most outstanding undercover agent, is interrogating one of the most dangerous criminal suspects of the 21st century. "It's a shame, Inspector Furuya, I used to admire you so much. Have you forgotten how close we once were?" "My friend, let me tell you what's going to happen so you can prepare yourself. Soon someone will knock on your door and call you out. There will be someone of higher rank in the lobby. First, he'll praise you for your great service, saying the world is safer because of you, and you'll receive praise and a promotion. Then he'll say I'll be released..." "My friend, my suppliers here come from Okinawa, Tokyo, Yokosuka, and Sasebo. Before you can even manage to get my partners..."

Lin Jin, who transmigrated into the world of Detective Conan, discovered something amiss with his dreams. In one dream, he unleashed a barrage of attacks on Ran, but the next day, she lost her match due to a muscle strain. He dreamt that Eri Kisaki was investigating a case of female assault, and he offered to help, cooperating in reenacting the case, which gave Eri a breakthrough the next day. He dreamt that he trained with Sun Wukong, and the next day he had eight-pack abs. "It's a pity dreams are random, otherwise…" Lin Jin felt quite regretful. If he could, this thing would be far more useful than time stop.

Official Introduction: Now approaching you is: Muzan's nightmare, the destroyer of the Twelve Demon Moons, the head of the Infinity Castle demolition office, the most righteous person in the Demon Slayer Corps, Sabito's savior, the eternal absentee of Kanae Kocho's tea party, Giyu's good senior brother, the founder of Fist Breathing, and a grandmaster.

Willow branches provide shade, that's it!

Kanae Kocho: "I invited him to a tea party ninety-seven times, and he refused ninety-seven times. He's so gentle."

Shinobu Kocho: "Why should I be trained by iron fists? It's infuriating, sister!"

Akaza: "A powerful person, the best in physical combat."

Muzan Kibutsuji: "A monster who destroyed all my Demon Moons with his bare hands and blasted the Infinity Castle to pieces, you call him human?!"

Unofficial synopsis: Yagyu In transmigrates to the world of Demon Slayer, but the system believes he is in the world of One Piece and identifies him as a Marine.

You can earn Navy Points and rewards by doing things that are in line with the Navy's rules.

Yagyu In: No, buddy, is this right? Where did this pirate from the Demon Slayer world come from that I need to catch?!

Pirates are attacking! Strike immediately to capture or kill them!

Looking at the man-eating ghost before him, Liu Shengyin realized that the system had gone mad.

From then on, the Demon Slayer Corps had one more instructor who liked to smash people's heads with his iron fist of love.

This book is also known as "Left Fist's Overpowering Entanglement Deals High Damage, Right Fist's Overpowering Entanglement Deals High Damage," "Three Punches Shatter Evil Spirits, Sir, I'm Just an Ordinary Person," "Overpowering Aura is Also Qi, and Qi is Breathing Technique!" and "Muzan, Are You Hiding Well? The Marine Admiral is Coming to Get You~"

Note: This book is a crossover anime/manga series, and will later explore other worlds.

Ghosts and monsters in the darkness spy on the human world.

In unseen corners, bloodshed and cruelty quietly grow. Ghosts eat men, men slay ghosts—millennial legends and grudges are intertwined with fate...

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.
