In fact, this explanation is somewhat unconvincing for Fang Yi.
After all, merely because of a whim, asking Old Wu to lead the Dragon Guards to intercept Zhou Yuzhu and Zhou Shuo inherently smacks of using public resources for personal purposes.
Fang Yi had considered this.
So, before he went to see Old Wu, Fang Yi realized that by doing so, he would owe a personal favor that would need to be repaid, yet Fang Yi still went ahead.
What does this indicate?
It indicates that Fang Yi owes Old Wu a favor.
In the future, if Old Wu's Dragon Guards encounter any trouble, with just a word from Old Wu, Fang Yi could lend a hand.
After all, there's no such thing as a pie falling from the sky. Fang Yi owes Old Wu a favor and naturally intends to repay it, even if Old Wu doesn't say anything, Fang Yi has that intention.
No one else knows this, but those who understand won't quibble over it.
