After that, there was no stopping him.

His walls were soon covered in medals of honor.

Planes, tanks, warships, missiles, satellites, aircraft carriers, submarines...

One incredible modification after another, technologies far ahead of their time.

By the time everyone realized what was happening,

China had risen like a soaring dragon, taking its place among the world's leading nations.
