Thirty years beyond the world of Dragon Ball, Li Changge gained the bloodline of the Saiyan Raditz through the System and joined the main cast. Using his foreknowledge of the plot, he steadily increased his strength. After more than thirty years of training, he finally went from a trembling little nobody to a Super Saiyan 4 powerful enough to command the universe. That's right, Super Saiyan 4. Now, with the Majin Buu arc about to begin, he has already broken through to Super Saiyan 4. His base power level is five billion, and Super Saiyan 4 multiplies it by four thousand. He has only one thing to say: Who's next?! On top of that, he has cultivated his divine realm to the fifth dimension, the realm of the Supreme Kai, and possesses a lifespan of one hundred million years.
In the first chapter, number 18 is the protagonist's wife, but in chapter 41, she becomes Colin's wife. Are you kidding me?
