This was what infuriated Song Tengfei the most. He gloomily went upstairs, fetched the property deed, and said as he came downstairs, "Since she's my daughter, I will personally accompany her to register her household."
The property deed was something Song Tengfei would never casually entrust to others; he only felt at ease holding it himself. This was the real reason he was willing to accompany Si Mingjing to register her household.
Si Mingjing, inwardly undisturbed, followed Song Tengfei to the police station to register her household. Afterwards, they went to the civil affairs center to have her ID card photo taken.
After all the procedures were completed, Song Tengfei said impatiently, "Since it was Old Master Su who brought you back, you should temporarily stay at the Su Family's place. On Earth, once children are over eighteen, parents no longer have a legal obligation to support them. I have other matters to attend to, so I'm leaving now."
