The Dragon Clan always took promises seriously, especially the kind that were sealed with a Blood Covenant.
The rise of the Dragon Clan had already excited him enough, but he hadn't expected to be tied to the same boat as Chen Qiu, a prodigy with a Twelfth Grade Golden Core and a Nascent Soul—and most likely, a Twelfth Grade Divinity Transformation Domain as well.
The Dragon Clan really hit the jackpot this time.
If Chen Qiu had no sense of gratitude toward them, if it had always been the Dragon Clan who was indebted to Chen Qiu, then they weren't sure whether Chen Qiu would repay them in the future or, worse, turn gratitude into revenge.
But now, it was Chen Qiu who was indebted to them, which meant that no matter how much he contributed now, Chen Qiu would certainly help the Dragon Clan in times of need in the future.
The people you help won't necessarily help you.
But those who have helped you are likely to help you again.
