本当は文字での説明なんてしたくないんですが
説明のために漫画形式で描くのめんどうですし本編中に
悟「ブウと戦ってる時の精神と時の部屋でさぁ…」とか
ただの辻褄の説明を言わせるのはさすがにイヤなので
お見苦しいですが文章でお願いします(時々言葉がおかしいです)
漫画内で伝えられない力不足で申し訳ない

I don't really want to explain in words.
I don't really want to give a textual explanation, but it's too much trouble to draw it in manga format, so I'm going to use the following words from the main story

Goku: "In the Room of Spirit and Time, when I was fighting Buu..."
or something like that.

I don't want to make him just explain the story.
I'm sorry if I'm not very good at this, but I'd appreciate it if you could explain it in writing (sometimes the words are not right).
I'm sorry I'm not strong enough to convey it in the comic.
