In the mindset of the Commander, not opposing Fang Chuning and Xie Jue is already being a very tolerant and considerate parent, just asking for a descendant, which is a really simple wish.
Fang Chuning was left speechless, feeling like his father was here to sow discord.
Xie Jue agreed to let Fang Chuning tell the identities of Ruyi and Mingzhu. From the Commander's words, he likely didn't know their backgrounds. As a father, having such thoughts and feeling uneasy was normal. Xie Jue was in a dilemma: he couldn't say they weren't biological as it might imply he didn't have his own children, and Fang Chuning wouldn't allow any, appearing too domineering. But if he didn't explain, the misunderstanding would linger, no wonder the Commander never showed him a kind face, despite seeing him before as a gifted, intelligent, and sensible child.
He couldn't easily say it, but Fang Chuning could. The Commander glared at him, "You made up such lies just to get me to accept you?"
