Ling Hua peeled the lychees herself, and naturally they were sweet. Yan Qing had earlier complained to Yun Luo that they were not sweet and said he wouldn't eat them, but after Ling Hua took over and peeled them for him, he ended up eating quite a few.
People who fear bitterness tend to love sweetness the most. Yan Qing had been drinking bitter medicine these past few days, feeling utterly bitter inside. Were it not for Ling Hua keeping an eye on him, he'd know that if he didn't take his medicine seriously, the injury might leave a permanent mark. Thus, he gritted his teeth and swallowed it thrice a day without fail.
So, the lychees actually arrived at the perfect time, alleviating most of his bitterness.
After Yan Qing shook his head and truly refused to eat anymore, Ling Hua peeled two for herself and asked him while eating, "Brother, before taking over the Green Forest new command and marrying me, how many times did you go to Jiangnan?"
