Now that I think about it there was been 3 different art styles throughout the whole series.
The first art style was from chapters: 1 to 19
The 2nd art style was chapters: 20 to 34
And the current artstyle starts from chapters: 35 to current
Xu An or Xu Yu? (絮桉) was the first artist, PoPo (魄魄) was the second, and the current artist according to the most recent chapters credit page are Firefighting Captain Xiao Fangfang (救火队长小方方) and Eat something good in the villa (在别墅里吃点好的)
Eat something good in the villa is the same artist from The Fallen Merman according to their Twitter account where they post drawings.
NOW for some reason there was a change in the credit page recently on chapter 62 and 63 'Eat something good in the villa' went from main, and only, artist to supporting artist. From then on 'Firefighting Captain Xiao Fangfang' became the main artist while 'Eat something good in the villa' changed to supporting artist. The art style still actively looks like 'Eat something good in the villa' art style so there is almost no changes, however if you pay close attention there are some parts in the art that look different. Like the chibi style.
I THINK this might be because The Fallen Merman is still actively being worked on by 'Eat something good in the villa' so in order to manage work they became the supporting artist instead. So far I haven't heard of new artist or changs, it might just be a misunderstanding of 'Firefighting Captain Xiao Fangfang' becoming the new main artist while 'Eat something good in the villa' went from main artist to supporting artist.
THAT IS WHY I THINK THERE WILL BE NO NEW ARTIST AND THEY ARE JUST TAKING THEIR TIME TO UNDATE, THANK YOU FOR COMING TO MY TED TALK
