In fact, Azure Dragon thought the same way: you obtained the remains of the Heavenly Fire Lion, had various gains, and might even be able to capture an Ancient God in the Annihilation State after your strength increases in the future—what's not to be satisfied with such great benefits?
Both sides were simply using each other for their own needs.
But Sun Daren was not a real "old fox" after all. Feeling that he had essentially been used, he became furious and immediately pursued with the "ambitious spirit of the youth" that still remained in his body.
The fact that Sun Daren could track him down secretly shocked Azure Dragon. It suspected that Sun Daren might have left some tracking secret technique on him!
He had already severed all connections; Sun Daren shouldn't have been able to find him. If there was some tracking secret technique that could deceive him... that would be terrifying.
