"You've finally completed the last mission your master left for you. He should be feeling at ease now." Upon mentioning Elder Lin, Qiao Dongliang's voice was full of regrets. It could be said that after Elder Lin left, aside from Qiao Nan's family, only Qiao Dongliang went to visit him.
He knew that when he was still committing mistakes and hadn't fulfilled his duty as a father, Elder Lin was the one who gave Qiao Nan recognition, care, and concern when she was going through difficult times. It could be said that without Elder Lin, there wouldn't be the Qiao Nan today.
Based on this point alone, Qiao Dongliang felt an infinite amount of gratefulness to Elder Lin. Elder Lin had made up for his shortcomings so that Qiao Nan, who was a good child, didn't go to waste. The most important thing was that such a good child shouldn't have been treated that way.
