This book is also known as "The Patriarch Who Likes Galleons Ran Away with the Potions Master Again" and features two male protagonists.

Severus Snape x Sirod Slytherin (with personal interpretations)

The isolated and helpless potions professor finally met his little rose, a story of black and white intertwining, confusion and fusion.

Upon entering school again, Sirod winked at Severus.

Severus: ...

Later, Sylvie asked, "Professor, do you believe in love at first sight?" while grabbing Severus's sleeve.

(There are parents and children. They are Tom's classmates. They don't like idiots and like Galleon. Severus will not like Lily and will only like Sir Lord.) (You can skip this if you don't like it.)

The phenomenal variety show "Love In" has launched with great fanfare. Lin Xia was fortunately chosen by the directors to participate as an amateur. However, according to the contract, he was required to portray an unconventional character to highlight the excellence of the other guests. This included, but was not limited to, being a scoundrel, a low-brow, sarcastic, stingy, narcissistic, abstract, and annoying... In short, he was to play a supporting role, attracting negative attention. After the deal was completed, the production team promised to pay him one million yuan directly. The director said, "I know this might embarrass you, so you should consider accepting this contract..." Before the director could finish, Lin Xia signed the contract almost instantly: "Director, don't worry. What's the point of embarrassment? I can't just give up the money for the sake of face, right? Don't worry, as long as the money is in place, I'll even let you have a seizure on the show, not to mention abstractions!" The director smiled with satisfaction: "I've always thought you're capable, young man!" However, two days later, as the show premiered, the director was stunned by the sight of the young diva covered in cow dung. So, he asked, what? Lin Xia: ...I just wanted her to stay away from me, to avoid my online girlfriend misunderstanding me. Who knew she'd actually explode? Little Queen: So is it possible that I'm your online girlfriend? Lin Xia: ??? Director: ??? Everyone online: ??? Wait, this is a bit confusing, give me some time! …… ……

Li Xiu died saving someone and obtained a system that allowed him to travel through various worlds and become a prince.

He agreed without hesitation. After all, he was all alone, and being able to live a second life was already an incredible stroke of luck, let alone becoming a prince.

However, after he traveled through time, he discovered that his identity as a prince seemed a little strange...

Others cultivate through comprehension, he cultivates through modeling;

Others rely on magical treasures to overcome tribulations, but he relies on calculations.

Others rely on luck to find treasure, but he relies on geological exploration and probability theory.

With his "spiritual energy dynamics," "array topology," and "elixir molecular formulas"—all considered outlandish and unorthodox by traditional cultivators—Li Haoran transformed a vague and illusory path of cultivation into a rigorous, precise, and quantifiable avenue of scientific research.

"Don't talk to me about the mysteries of the universe. In my eyes, everything can be quantified!"

"If there are bugs in the Heavenly Dao, I will personally debug them!"

I traveled back to a remote and impoverished village in ancient times, and by chance, I encountered the government officials choosing wives for their children, and each of them was incredibly beautiful!

Li Yu transmigrated to a dangerous fantasy world, but fortunately he had the golden finger that every transmigrator needs, and the golden finger was the legendary supreme qigong---Divine Elephant Suppressing Prison Force!

Using Qi to guide the spirit, and the spirit to form an image, every gesture and movement carries the power of a giant elephant. The human body is composed of 840 million particles. If its potential is awakened, every tiny particle is the power of a giant elephant. When all of them are awakened, they are comparable to a divine elephant, capable of overturning rivers and seas, roaring down stars, plucking the moon and swallowing the sun, all in the blink of an eye.

Elephants come in countless varieties and transformations. The giant elephant, as a child, transforms into the dragon elephant; the dragon elephant, in its green form, transforms into the primordial elephant; the primordial elephant, in its mature form, transforms into the divine elephant. This is the ultimate form.

With such extraordinary skills, only one problem remains for Li Yu!

That is... practice!
