The Dragon Ball has become a great reliance of American nemesis. No matter the internal structure or the chaos of external forces, as long as there is any problem, the American nemesis will summon the Bolunga God. As long as the Dragon Ball is lifted, the American nemesis will make three wishes that were wanted at that time, and it will be in vain if it is unnecessary! Why don't the old gods cultivate youth? I think it is impossible to recover, or it has great limitations (doctors don't treat themselves). Please recall that in the nemesis incident in the United States, the elders did not repair their youth according to the Dragon Ball to resist Felisa, but only watched their descendants be killed.
Moreover, in the process of Super One-Star Dragon clearly proposing to combine with old gods, Super One-Star Dragon has crushed old gods according to its combination with Nei Lu. In addition, God has entered old age, and Super One-Star Dragon coincides with young and middle-aged people, so the combination of Super One-Star Dragon and Old God is the best! Because even if the old god is young, he may not be able to improve his energy after assimilating with Super One-Star Dragon. The combination and assimilation of nano-busters and ancestors should take one of the two groups as the main body of assimilation, gain the ability, memory and energy of the other person, and become stronger.
On the surface, it may be that Super One-Star Dragon combined with the old gods with stronger overall strength can gain more energy, but in fact such a thing is impossible. Because the overall strength of repairing the soaring youth has not really enhanced energy, but has restored the overall strength that the young age could not give full play to because of the situation of the elderly. The average life expectancy of enemies in Nami is so long, and the development of natural environment has harmed a person. In Nami, it is very rare for natural enemies to have elder education, which is too bad. However, God floated around the earth in a spaceship in his early years, and people's slaughter and struggle on the earth hurt her. So much so that he wanted to be a god, and the previous generation of gods refused, saying that he was too delusional.
