Ling Sheng secretly despised her Fifth Uncle in her heart. She was angry. Not only had he snatched her food, but she had deliberately saved the mutton balls for last. If she had known that he would come, she would have started with them.
Besides, she had gone from calling her Sister Yu to calling her Aunt Yu. Their seniority was one generation away.
Lu Yubai had initially come to see her and apologize on behalf of Huo Ci. Since Ling Sheng was here, he could not talk things out. After snatching the barbeque and eating it, he walked away. When he reached the door, he pointed at Ling Sheng and reminded her, "Watch your Aunt Yu carefully. I'll take care of your… granduncle."
After saying that, he felt a lingering fear and nearly fainted. I almost said your 'father'.
Thankfully, he'd reacted quickly and changed his mind.
