The meat must be freshly slaughtered, and there are also fruits and other grains!
Even though Eryao is a glutton, he is also skilled. Back in the day, he took care of Jiang Tang as well. He didn't return to a fixed residence nor visit Sir Zheng's place!
He's been flying in the sky all along, roasting meat inside a Magical Treasure, drinking wine while eating!
As for Sir Zheng's place, he left a courtyard for him, allowing him to stay there anytime!
Eryao isn't an ordinary human, so how could he possibly stay in a mortal's house all the time?
As for the mortals' way of thinking, they are grateful to him. As long as there is faith, that's enough!
Eryao also noticed that the old witch used academics to create an Evil Technique, manipulated a Heavenly Master, and even received backlash herself. The Heavenly Master was present and was reprimanded at the time!
