In the 34th year of Konoha's reign, the Uchiha clan produced a mission fanatic. If you ask him why, he can only tell you—"I need to accumulate experience to level up by drawing cards!" Drawing character cards: [Uchiha Madara (Young)], [Namikaze Minato (Adult)], [Uchiha Sasuke (Team Taka)]... Madara: I see a reflection of my younger self in him. Minato: I feel like I've always lived in the shadow of Genji. Fugaku: Oh no! This kid's after Mikoto! (This is a 1.5 million word high-quality Naruto fanfic by an experienced author; feel free to read it.)

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.)

With the merging of the two realms and the revival of spiritual energy, demons, ghosts, and dark creatures from another world simultaneously appear in the world.

The passionate young man Yu Zhibo obtains a system panel, awakens his Sharingan, and can use various ninjutsu!

What? Lightning attribute has a counter effect on demons and ghosts?

I have Chidori for single-target kills and S-rank ninjutsu Kirin for full-coverage bombardment. Are you scared?

Are dark creatures afraid of fire?

My Great Fireball Technique can obliterate you into dust, cremate you, and reduce you to ashes in one fell swoop!

Under my ninjutsu: all demons and monsters will be reduced to ashes!

Under my Sharingan: all disguises will be exposed!

Illya: "Yu, you went to another world to gain the power to save me, right?" Emiya Yu: "That's right." Chloe & Miyu: "Then what's with all these girls sitting on the sofa?" Upon hearing this, Emiya Yu looked at the Burst Mage, the Blue Ribbon Goddess, the Gluttonous Sisters, and the Elf Family sitting on the sofa, and said naturally: "Oh~ my dear Illya, Miyu, and Chloe (Kuro), saving the world and chasing girls don't conflict, do they?"

Su Can, who had just been admitted to university, died unexpectedly and ended up in a place called Mingbei High School.

In this cruel world, he chose the path of a cultivator to strengthen himself, completing one impossible task after another, all for the sake of obtaining that damned university acceptance letter.

When mathematical genius Lin Xian opened his eyes, he didn't see a world of flesh and blood, but a rational realm flowing with formulas and data. Having traversed the world of cursed warfare, curses were no longer indescribable terrors, but chaotic equations awaiting deciphering.

"The character '茴' in '茴香豆' (fennel seeds) has four ways of being written—while the curse of death has seventeen optimal solutions."

He pushed up his glasses at the super-grade cursed spirit that was devouring heaven and earth: "Your probability of existence is approaching zero."

He unfolded a draft paper over the tangled web of a thousand-year-old conspiracy: "There is a sudden change point in the entropy increase curve of your plan."

He even wrote a proof against Gojo Satoru's limitless technique: "The so-called infinity is nothing more than a romantic illusion of convergent sequences."

However, as the blood of Shibuya stained the mathematical model, and as the prison gates swallowed the last glimmer of light, Lin Xian finally discovered—

The deepest curse in this world is never the power of magic, but human nature.

The ultimate destination of reason may not be on paper, but in the wheat field growing beneath our feet.

This is the ultimate battle between reason and mystery.

"When absolute rationality collides with the variables of human nature, the entire world of sorcery will tremble."

Shimizu Mitsuki looked at Hyuga Hiashi with exasperation: "What are you calling me 'son-in-law' for! How many times have I told you, use your job title when you're working!" Sarutobi Hiruzen immediately said, "Mitsuki, look at my fifty million..." "Fifty million? Three hundred million!" Shimura Danzo immediately got drunk: "Mitsuki! Are you preparing a surprise for us old guys?!" Shimizu Mitsuki just shook his head and remained silent. How high does one's position have to be to be considered high? Back home, Yukino Yukinoshita had a blank face. "What's so good about that Sakayanagi Arisu? Why are you so infatuated? Tell me, I want to learn from her!" Shimizu Mitsuki just sighed and replied, "I'm just loyal to love." "But you're loyal to your love for them!" Shimizu Mitsuki didn't want to argue, he just wanted to say, "Let the evil wind of everyday anime's beauty trap blow in!" (Harem, minor ensemble cast)
