After Wen Yao arrived in the Hell of Gensokyo, Shiki-sama's daily life became like this: In a singularity, discussing the meaning of death with Ereshkigal, the goddess of the underworld; Izanami, the goddess of the underworld, confiding in someone about her loneliness in a broken world; exploring souls and the abyss with Ash (primarily Gensokyo)... Primarily Gensokyo, interspersed with other worlds, the narrative will likely not follow the above pattern. A mix of first and second settings, the setting is not rigorous (updates will be irregular for now; daily updates will resume after the previous main story is completed; I will try to maintain uninterrupted updates during holidays). PS: If Shiki fans can't find any Shiki-sama fanfiction, they'll have to write their own. PS: I'm bad at creating summaries; this is not the final version.

Reporter: "Mr. Daidouji, many people say your policy platform is too radical. What's your opinion?" Daidouji Sousuke: "The more they oppose me, the more it proves I'm right." Reporter: "And some people say that after you joined the Metropolitan Police Department, the level of crime in Japan suddenly escalated. What's your opinion on this?" Daidouji Sousuke: "This proves that our law enforcement methods are still too lenient and haven't deterred criminals." Reporter: "Then could you explain why your election opponents are often involved in inexplicable murder cases? How do you control all of this?" Daidouji Sousuke: "Sorry, no comment." Watching this finally revealing scoundrel leave, Daidouji Sousuke sternly ordered: "Come on, take Conan to this reporter's house for two days..."

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.

"Style Reversal: Gödel's Incompleteness"

"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.

[A hardcore epic that rewrites the rules of magic using mathematical formulas]

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

[Comprehensive anime, Japanese light novel, slow-paced, currently involved in the series "Borrowing Girlfriend", "A Silent Voice", "Rascal Head" and so on] He is the childhood sweetheart of the hearing-impaired girl Nishimiya Shoko, and he directly fought back against the school bullying suffered by Shoko; he is a loyal fan of the best-selling light novel author Kasumi Shiko, and the sales of "Love Metronome" have skyrocketed because of him; he is the childhood playmate of the well-known backstage painter Kashiwagi Eri, and he agreed to let her be his exclusive painter;... Itsuka Yuuto traveled to the world of comprehensive anime and obtained a system that calls itself a "love simulator". He thought it was an ordinary text game, but the system threw him directly into the simulation world! "Wait, why do I have to die every time the simulation ends?" "System, didn't you say that the simulation world does not affect reality? Then what's wrong with these people!"

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)

Hachiman Hikigaya: "No, please stop broadcasting! You'll get killed, you really will get killed!" Yukino Yukinoshita: "Hehehe, Hachiman-kun, another one! What am I supposed to do?" Haruno Yukinoshita: "Eh-le-le, ah-le-le-le, even I'm smitten after watching this." Yui Yuigahama: "Hachiman,..." Although it's a video, this isn't good. "Iroha Isshiki: 'Senpai, you have to take responsibility for me!'" Kawasaki Saki: "So I've already given myself away?" Totsuka Saika: "Why haven't I been chosen yet? Am I even a girl? I really want to be with Hachiman!" Hikigaya Komachi: "Eek! I'm not his biological child after all??? Get out of here, you stinky women, let go of my Onii-chan!" Kyoka, Rumi, Hina, Yumiko, Jun: "Even we have him???!!" "You guys are alright, I'm the most outrageous one!!!" Orimoto Kaori (ex-girlfriend): "Get out of here, I finally get to get married, and you're all trying to steal him away, get out of here!" Hiratsuka Shizuka

[Naruto + Hypocrisy + Dark Themes + Ruthless Methods + No Female Lead]

I transmigrated into the world of Naruto and became the Uchiha clan, obtaining the [Inheritance System].

As long as the deceased's approval is obtained, all of their abilities can be perfectly inherited.

And so, I became the gentlest sunshine and the kindest genius in Konoha.

I told Kakashi, "White Fang is a true hero."

I said to Obito, "The dream of protecting your comrades is incredibly noble."

I said to Itachi, "I feel your pain."

Everyone thought I was the light that illuminated the darkness.

They didn't know that I personally guided my parents to the battlefield and smiled as I bid farewell to each of my "closest friends."

I wept before the memorial and mourned at the funeral.

Until the night of the annihilation, I stood on Fire Shadow Rock, looking down at the burning territory of my clan, and opened my arms.

"Thank you for being the nourishment that helped me reach the summit."

When the spirits of all the past Shadows crown me, calling me the Savior...

I laughed.

"No, I'm just a professional estate harvester."

(Real-world mutation + grand adventure)

I've traveled through time and space and become Yuuki Mamoru, diligently training to face a world-ending crisis. And you tell me this is a manga? This is an abstract, entertaining book that will make you forget your worries and smile. Note: The protagonist has morals but no moral boundaries.

What would happen if you replayed the story with your max-level account? Gudako looked at the dazzling array of Servants on the Silver White Servants and clung to their thighs. "Please carry me, boss!" Black Saber stared wide-eyed at Morgan from the Lostbelt. "You are! My sister!" Jeanne d'Arc looked at Metatron Jeanne lazily leaning against the Silver White Servants and vehemently denied it. "This lazy guy isn't me!" Nero stared at Draco, the Sixth Beast, in front of her, stunned. "You mean, this human evil is Yu!" The Silver White Servants arrived at the Grand Temple of Time, with Draco on their left, Ereshkigal on their right, and the Director of Unbeast behind them. "Goetia! You're not at the Grand Temple of Time! Where are you!" System, harem, mindless, lighthearted, a little bit of romance, slow pace.
