It had only been one year since the twenty-second World Martial Arts Tournament.
According to the original storyline, two years later, at the twenty-third World Martial Arts Tournament, Goku would marry Chi-Chi.
Four years after Goku and Chi-Chi married, Goku's older brother Raditz would arrive on Earth, kicking off the fierce battles of Dragon Ball. Goku and the others would also frantically raise their battle powers amid those brutal battles.
There were roughly seven years left. He-El did not intend to stay on Earth and wait for seven years, nor did he intend to spend two thousand five hundred and fifty-five years inside the Hyperbolic Time Chamber.
He planned to explore the starry skies of this universe and study higher-energy foods to aid his training.
"Earth Shenron's knowledge is still far too shallow." As He-El considered Earth Shenron's knowledge, he found it far too limited for his needs. Though he had absorbed it and used it to strengthen his battle power, and had also used it to create high-energy capsules to assist his training, it was still not enough. It was far too insufficient for He-El.
Perhaps it had something to do with Kami and Earth. Their knowledge only extended this far.
Kami had merely arrived on Earth as a child. The Shenron he created was tied to his own knowledge and abilities, and Kami's abilities could not exactly be called powerful.
Although Kami had been a gifted child on Namek, in He-El's eyes, he was only so-so.
On his home planet Namek, Porunga, created by Namek's Grand Elder, possessed far superior capabilities to Earth Shenron. He-El believed that perhaps he could gain more knowledge of this universe from Porunga, allowing him to create miraculous food comparable to Senzu Beans and use it to restore his stamina after training.
