Can we meet our need for historical accuracy by adding more realistic graphics to the limited-time event rewards?

Just like the reward of replacing the house with the yurt graphic in the previous Mongol King incident,can historical accuracy graphs be gradually introduced in this way?

I saw this different Central Asian castle in the 2019 promotional video. I think it is more beautiful than the current one. Can they add it as a graphics module?


I think the past styles look better,Richer and more refined.
