Ma Lin estimated that he would have to take over these tasks for about a month. Brother Fa wasn't spending all day playing with a bunch of girls either; he would also get some work done when he had free time.
The reason Ma Lin didn't join in the fun himself was twofold. First, he had just returned from Mount Naizi, where he had been playing for over a month; if he didn't work now, everyone would scold him. Second, he was, after all, a demon lord in training and had his own serious matters to handle.
Picicki kept complaining about why Ma Lin didn't take her with him to Mount Naizi, while Zhao Tumei was as busy as a little bee, not only working on the construction of the divine city at Elmina's but also taking care of Ma Lin's parents. These two definitely deserved a vacation.
