Over two hundred years ago, the Great Demon King Piccolo gathered all seven Dragon Balls and summoned Shenron. He asked the dragon to grant his wish to become the strongest person on Earth.
Piccolo thought he could rule the planet, but Sun Wukong returned from training at the Divine Tower. He challenged the Great Demon King Piccolo to a duel at Two-Finger Mountain, and in the end, Sun Wukong used his ultimate attack, taking them both down.
Two hundred years later, Sun Qingqing, a descendant of Sun Wukong, set out to revive her great-great-grandfather. She rode her unfailingly sturdy blue horse across the world in search of the Dragon Balls.
When she reached the Two-Finger Mountain where the fateful battle had taken place, she met the highly skilled Wang Long. Hoping to recruit him to her team and search for the Dragon Balls together, Sun Qingqing told him her family's secret.
At first, Wang Long didn't believe her. But after he learned to control the Flying Nimbus and the Ruyi Jingu Bang, he finally realized it was all true.
So Wang Long agreed to join Sun Qingqing on her quest for the Dragon Balls, hoping they could summon Shenron and each have their wishes granted.
