Lin Fan was important to Xin'er, the Mu Stellar King recognized this.
He was even sometimes jealous that Xin'er was closer to Lin Fan than to him, her actual biological father, but he also couldn't blame her.
Lin Fan had been the one who had taken her in when she was at the lowest point of her life and had been the one who provided love and care to her, it was inevitable that he would have a high position in her heart.
That was why he hesitated now.
This war wasn't something that would end quickly, it was very likely that Xin'er would be separated from Lin Fan for months or even years.
This wasn't something that he wanted to force onto Xin'er when she was still so young.
If the worst case scenario came and something were to happen to Lin Fan, then…it would be hard for her to ever recover.
