Fearing the powerful faction that might be backing Jiang Qiu, the Nine-tailed Fox opted against making a bloodline oath, settling for a simple verbal wager instead.
He didn't dare force Jiang Qiu into a situation with such high stakes. While strength was paramount for survival in this world, intelligence was just as crucial.
The real key was to be prudent and protect oneself, not to be overly greedy. He didn't believe he could win the bet, take Jiang Qiu's bloodline, and still live to tell the tale.
That was why he'd given up on the bloodline bet with Jiang Qiu, opting for a verbal agreement. Besides, deep down, he didn't really believe Jiang Qiu could help someone reach the Spirit Control Realm in three hours, so he wasn't too worried about losing many of his Spirit Fruits.
Besides, worst-case scenario, it would just mean giving one Spirit Fruit to Jiang Qiu. That would already be a huge gain for him, so he likely wouldn't press the matter further.
