The answer Zhang Hei got from Jun four days ago was: "I just want to help."
The question was whether Jun would agree to become Mo Lan's son or not, but that was what Jun had told him, and Zhang Hei could actually be sarcastic about the young man if he wanted to.
If he wanted, he could sneer at the young man and say, "Just say you want to be a rich man's son. You will be a young master, and your life will be easier, right?"
Zhang Hei could have said that, but he didn't. Instead, he just listened to what the young man said to him without giving a response. It had been four days since that day, but Jun was still not Mo Lan's son. The young man was busy with his training schedule, and he probably didn't have time to think about Mo Lan's offer. The young man probably also didn't have time to meet the old man and talk about his decision.
