Everyone, please note: this isn't a blood-pumping sports competition novel!
Although it uses the setup of a coach, it's mainly a modern urban progression story with high-martial elements.
Here's the synopsis:
[Urban] + [System] + [Feel-Good Story] + [Creative Premise] + [Making Money] + [Skill Advancement] + [Pseudo-Invincible Early On]
After Li Ming obtained the System, his daily task was to make training plans for his students. As long as they completed their plans, he would receive rewards.
[Ding! Otherworldly resident Kyle has accepted a training plan. Host receives a 1,000,000 reward.]
"Holy crap, now that I'm rich, what should I do? Spend it, of course!"
While going to eat beef noodles, Li Ming casually spent 500,000 to buy the noodle shop.
[Ding! Kyle has completed a week's training plan and awakened the Mighty Strength talent. Host has obtained the Mighty Strength talent and Dwarf Wrestling, and received a 1,000,000 reward.]
Li Ming had now become a SUPER-MAN.
Student reviews:
"I really admire Li Ming. He helped me become strong!"
The dwarf Kyle praised Li Ming.
"I'm very grateful to Li Ming. He helped cure my nearsightedness."
The elf Alice thanked Li Ming.
Li Ming was baffled. He'd opened a gym, so why were most of his customers from other worlds?
