The title of dragon ball

1. Old Kaiōshin gave him "alive", not his life span.

The key is that Toriyama Akira separated them.

If we have to find an objective reason, some people believe in the "air theory", but I don't agree. First of all, the air theory is based on the fact that Wukong was puzzled after they separated, saying that it might be caused by the air monster here. Note that even Wukong himself is not sure here and should not be used as a basis. Portela's earrings will really become a person and cannot be separated. So for a warrior as powerful as Becit, just one air difference can separate them? Because even without air, it can live for a long time. If portela's earrings can be separated when they enter Buo's body, then Kaiōshin can also separate them.

In addition, in the animation of Dragon Ball Z, Kaiōshin and Kaiōshin, who are combined with portela earrings, have only one voice, while Becht has two voices. The same nature as Gotenks or Gogeta.

In other words, Becit can be separated, which has been decided from the very beginning of the combination. His fit can be divided, and it's not just Bouvier's.

Of course, if you only rely on comics and don't care about animation, this passage can be ignored.

There are two possibilities for why Becit can be divided into groups. One is two. It's too powerful. The energy is too high for earrings. Second, Vegeta was dead and Wukong was alive, which was illegal.

3. Kaiōshin is different from the earth, and the soul can stop directly on it. Plus old Kaiōshin is a civil servant after all.

4. Obviously, it has not changed.
