Regarding Ultra Instinct, Whis had given Lu Li a brief explanation while they were eating on the road.
It was a state of perfect freedom, where the mind was empty and the body moved with intent. Whis said he knew how to train someone to learn Ultra Instinct.
But Whis also told Lu Li that everyone's path to learning Ultra Instinct might be different. Beyond the foundational, systematic cultivation, it also depended on one's state of mind. Some people could train through conventional methods for ten thousand years and still never learn Ultra Instinct.
Others, after only simple systematic training, might comprehend it on their own in actual combat.
This was not a difference in martial arts talent, but a difference in spiritual realm and personal character.
Take Vegeta as an example. In the original story, Vegeta had not mastered Ultra Instinct in its traditional sense. Instead, under Beerus's guidance, he developed his own form of Ultra Ego.
That suited the prince's personality perfectly. He did not possess Goku's pure-hearted nature. His personality was intense, and he was absolutely not the kind of person who could completely empty himself.
So, based on Whis's words and Lu Li's knowledge of the original story, he felt that everyone could cultivate an Ultra Instinct suited to themselves. They simply needed proper guidance and the right direction.
