Crossing through Fuyuki, looking at the blood-red pattern on the back of his hand, Novell decides to speedrun the Holy Grail War alone in order to avoid becoming a victim of everyday gas explosions.

—————

"Ahem, Tohsaka-san, what do you mean I'm some old monster who's lived for who knows how many years? I just recently learned a few little tricks so I can survive in the Holy Grail War."

Novell looked at Rin Tohsaka across from him, whose eyes were filled with deep suspicion.

"Huh? You're asking me why I'm so skilled at rune magic?"

"Of course, it's all about practice, cough, practice makes perfect."

Just because he glanced at a pretty girl on the bus, he was labeled a shallow guy by a cold, aloof girl?!

Akiyama Shin retorted expressionlessly!

"If you are in the habit of making judgments about people based on only one-sided observations and believe them without a doubt, it only shows that your level of cognition may only be at the level that you despise."

Due to family circumstances, Akiyama Shin came to this highly successful preparatory school that boasts a 100% success rate in college admissions and employment.

But Qiushan knew better than anyone else that there's no such thing as a free lunch!

A monthly bonus of 100,000 points? Relaxed and free campus management?

"The school's annual expenses are truly astronomical..."

Less than an hour into the semester, someone asked how many points it would cost to buy a night's worth of tea stalks and edamame?

Use your own strength as leverage for cooperation!

After forming an alliance with Chahashi Sae, he turned around and sold the information he had deduced to Class B for 2.8 million points? And then made his first fortune!

When Horikita Suzune finally saw Akiyama Shin's true strength, she understood the difference between the stars and the universe.

"Being with you..."

"On the contrary... I feel very happy."

On his journey of wits and strategy to lead Class D to a comeback and advance to Class A, Akiyama Shin is forced to unlock a romance side of his life!

On one hand, there's a carefully orchestrated power struggle within the campus.

On one hand, there's the allure and entanglement of beautiful women?

This game where skill reigns supreme…

Only I, Qiushan Shen, will have the last laugh!

"Take this apartment."

"Wear this watch."

"Here, take this card."

"I told you, I'll take care of you."

Lin Yi looked at Yoona's domineering demeanor and smiled. He was almost full from being a kept man.

Just then, a laugh came from behind.

"Oppa, when are you going to do something naughty? Take me with you!"

Looking back, a lovely girl stood smiling sweetly in the sunlight, radiant and charming.

Reborn into the Great Wu Dynasty, Li Changsheng becomes a (fake) eunuch in the imperial harem. He aspires to be like Lao Ai, but instead becomes the strongest eunuch on Earth.

In terms of political achievements, he established schools, implemented reforms, rectified official corruption, swept across the land, and brought peace to the world for generations to come!

He fought against powerful ministers, but in the end, he inexplicably became the most powerful minister and the most treacherous traitor!

When it comes to economic development, he transformed the once precarious Dawu into a prosperous and powerful nation, even surpassing Tao Zhugong!

In terms of talent, if all the talent in the world were equal to one bushel, he alone possessed twelve bushels, and the rest of the world would owe him two bushels!

A man of many talents, he wielded power over the world when awake, and rested his head on the lap of beauties when drunk. Princesses, imperial concubines, noble ladies, and chivalrous women all loved and admired him.

...

The stunningly beautiful empress later looked back and thought: "You dog of a man, I asked you to manage the harem, how could you have dug it all up?"
