Large wall print ppi

I was provided a key visual psd file from the client 27"w x 20"h at 200ppi and I was asked to create a full print wall graphics using the psd provided. The wall was quite big, around 35 feet wide and 8 feet tall. And even knowing the minimal ppi for printing should be 180, my computer just cannot handle file that is so big. I could only do 700ppi at 1:10 ratio with my computer capcity, meaning it'd be at 70ppi only when it's printed at actual size.

I wonder what I should do in this situation? The gigantic file is making it very difficult for even the smallest edits and it takes tremendous time to save. What ppi should I be working at for this scenario? Or if there's any workaround solutions that could make an alright print quality yet still have the computer running okay? Thank you!

Extra info: the wall graphics is used a confined exhibiting space as decoration, to take viewing distance into consideration

Resolution requirements for large scale print are always vastly overrated. Even if you walk straight up to it, 80 -90 will be perceived as absolutely crisp and sharp.

If you have a standard desktop monitor, you're looking at 95 to 110 ppi. Do you see pixels? Is it not sharp enough?

As a general rule of thumb, there are extremely few practical scenarios where you need more than 15 000 - 20 000 pixels on the long side. Unless you're NASA.

Here's a practical demonstration. These two images were shot with a Sony a7r V, the highest resolution 35 mm camera available today at 9504 x 6336 pixels. The bottom half is a 100% crop. Look at that in a separate window to see it 1:1 at your native screen ppi.
