Superpowered Underachiever of the 1990s

In the apocalypse, the R virus spreads across the globe. Monsters swarm and zombies run rampant. After countless hardships, international police officer Ling Su finds a time machine and prepares to travel back to stop the disaster from happening. But the machine overshoots, sending her back to 1999.

Fortunately, she still has her superpowers from a genetic mutation. She's just twenty years younger and back in high school.

School bully? No such thing. She can take on ten with one punch.

Fitness test? Not a problem either. She can run 800 meters in ten seconds.

But...

What are the Three Su's? And which seven are the Seven Sages of the Bamboo Grove?!

“Odd functions change sign, even functions don't...” What on earth is a quadrant?!

Ling Su hasn't touched a textbook in over ten years, and she's completely bewildered.

What's more, she's shocked to discover that a transfer student named Lu Zhengnan has joined her class. He's none other than Lu Zhengnan, the notorious developer of the R virus!

Ling Su sits in the corner, gazing meaningfully at the tall, clean-cut boy in a white shirt at the front of the room. There's only one thought in her mind:

He's so handsome. I should strangle him!
