Ninety-Nine Years of Tennis

This story has been changed to no CP [Thank you on my knees]

"Shocking! The Youngest Grand Slam Champion Announces Immediate Retirement While Accepting His Award!"

A devastating loss for an entire era!

"Senior Yun Ying, how did you manage to win a Grand Slam at such a young age?"

"You started learning when you were little? That's incredible. Senior Yun Ying, you're my idol!"

"Could you teach me how to play tennis, senior?"

Listening to all the chatter around him, someone who had been using cheats without ever turning them off took a deep breath.

You want him to play tennis too? Do you people know how long he's been getting thrashed... no, playing tennis?

Not nine years, not ten, not even twenty. He'd endured a full ninety-nine years of the System's hellish training.

Those skills and instincts everyone praised as extraordinary and almost supernatural weren't innate talent. They were paid for with his blood and tears!

"May there be no tennis in heaven..."

That senior murmured, then waved and turned to leave.

"I'm done. I never want to play tennis again in this life. Kids, find another idol!"

System Mission:

If the Host wins a Grand Slam before turning sixteen, they will receive limitless wealth and an immortal life filled with health and vitality! Tempted? Then take action!

Yun Ying sat in his wheelchair and tapped his leg. "So... what's the price?"

"Jealous of my amazing physique?"

"Yeah."

"Easy. I never turned off my cheats."

"?"

"How can I get a physique as strong as yours, senior? By sticking to a daily exercise routine?"

"Oh, yeah..." The man nodded, his expression sincere.

No need to spend 998. Take away the 8, and for just 99 years, anyone can become this indestructible.

Important Notice:

This is a pure wish-fulfillment story with a protagonist adored by everyone. No CP.

For special reasons, the protagonist is probably going to be pretty gloomy. Anyone who played tennis for ninety-nine years at the highest level and faced countless elite masters would end up like this.

Theme: Know what you have and what you lack; know what to do and what not to do.
