Old Devil Yu could still have children.
But he didn't think he could produce another child superior to Ji Changsheng.
Besides, he guessed that even if he did have another child, with Ji Changsheng's methods, he'd probably strangle his own brother in its cradle.
Having observed Ji Changsheng's way of doing things, Old Devil Yu had absolute confidence in this.
So, it was best not to waste that effort. Focusing on nurturing Ji Changsheng was the optimal choice.
"In a hundred years, I'll ascend to the Primordial Immortal Realm and Changsheng should have grown up by then. Us father and son, joining forces and ruling this world for a thousand years, shouldn't be just a pipe dream!"
"Big brother, we're bound to succeed." Yu Jidao was also full of ambitious aspirations.
...
Naturally, Ji Changsheng had no idea that his cheap father had already thought things through for him very thoroughly.
He was in the middle of complaining at this moment.
