I Activated Young Adult Mode

A nine-year-old boy accidentally turned on Adult Mode on his phone.

From then on, he suddenly gained the intelligence and physical strength of an adult.

He crushed students from across the city in exams, competed in all kinds of sports against a muscular PE teacher, and played video games against a computer teacher who was practically a professional.

He represented the city in math, physics, and literature competitions, represented the province's youth in winning the World Robot Contest, and represented China's primary and middle school students in delivering a speech at the United Nations...

A world experienced at just nine years old could be this exciting!
