Looking at the Metamoran before him, Son Gohan greeted him, then politely asked whether he would be willing to teach him the secret fusion technique.
Having witnessed Son Gohan's immense strength earlier, and seeing how politely he asked, the Metamoran had little hesitation in teaching him the technique.
During this time, Son Gohan also felt some regret, because even the Metamorans had no way of explaining exactly how fusion worked.
However, based on the fusion movements and its basic requirements—similar ki and similar body types—Son Gohan deduced that its principle should involve fusion on a microscopic energy level.
So Son Gohan did not dare alter or simplify the movements, and simply recorded them exactly as they were.
"Son Gohan, would you be interested in staying here to train?"
Just as Son Gohan was preparing to leave with North Kai, Grand Kai suddenly appeared before them and asked Son Gohan this question.
Son Gohan naturally shook his head. "Lord Grand Kai, I still need to return to my planet. Once I've dealt with the troublesome problems there, I'll make time to come back."
Grand Kai nodded. "In that case, go back first. You can come whenever you want, anyway."
Grand Kai already knew that Son Gohan possessed the skill Instant Transmission and could come to Grand Kai's Planet to train at any time, so he no longer tried to persuade him to stay.
After saying their goodbyes, Son Gohan took North Kai and used Instant Transmission to return to Kai's Planet.
But the instant they appeared, Son Gohan saw a familiar figure.
"An, Angel?" Seeing the visitor's appearance and attire, North Kai immediately trembled in fright.
"Mr. North Kai, I have something I'd like to discuss with Son Gohan. Could I trouble you to excuse yourself?" Marcarita asked with a smile.
