But Qiao Yu, you need to understand that this matter has nothing to do with Senior Brother Chen, nor does it have anything to do with your mentor. I'm simply giving you a hand because you asked me. I'm not expecting anything from you, but I want to tell you that favors are the hardest things to repay in this world.
Grandpa is already old, it doesn't matter. But in the future, you must remember not to casually owe favors over trivial matters. Especially as your status increases, it's even more so. You can consider this as a way to maintain relationships, but make sure it's used in the right places."
Qiao Yu nodded, saying, "Understood, Grandpa."
...
No matter what, Qiao Yu felt he had fulfilled Senior Brother Chen's request. After quietly having dinner with the elderly at Huaqing, he returned to Yanbei.
On the way back, Qiao Yu carefully thought through Elder Yuan's handling of the situation, finding it quite amusing.
