Transmigrated Villain, Starting by Taking Care of the Protagonist's Concubine

Upon waking up, Zhang Yu found himself transmigrated into the body of a villain in a book.

Seeing the trembling aunt of the main character in the secret room, he secretly felt something was wrong.

Q: What should I do if I offend the main character?

Fortunately, the villain system is now online!

Since that's the case...

Taking care of the protagonist's aunt earns "Romantic Points," which can be used to enhance the protagonist's cheat abilities.

[Kill the protagonist Fang Ming and plunder the cheat code—the time portal]

[Kill the protagonist Jiang Li and plunder the cheat system - hint]

[Kill the protagonist Zhou Qing and plunder the cheat code—the Longevity Fruit]

...

Many years later.

Zhang Yu looked at the time portal, the prompt words, the "Many Children, Many Blessings" key, the "Book of Ten Thousand Generations," the stat allocation panel, and all sorts of cheat codes in his hand, and fell into deep thought.

Which one is better to use?
