One reason was that the Ghost Prison was too bitter and exhausting, which left him physically and mentally fatigued. He really wanted to have a good rest.
In these two days, he neither got up early for training nor stayed up late to practice the sword.
He just slept, wishing he could make up for more than a year's worth of lost sleep in one go.
Then there was cooking, preparing various kinds of delicious food for Little Fatty, making his already plump figure even more full-rounded, and his complexion more rosy and lustrous. Anyone who saw him would have to praise, "This child is blessed"...
Moreover, he also needed to find a proper excuse to see the old man.
He had no kinship nor old ties with the Gongshu Family, and it would raise speculation about their relationship if he went to visit them immediately after returning.
The old man had said that the Shen Family might already be suspecting their relationship, making Tang Fei have to be cautious.
