[Tsv] Wither Skeleton Farm

I have recently found two optimal places to put an extreamly efficient semi automatic wither skeleton farm. One of these locations i have alreayd built up a wither skeleton spawning pad which contains a total of 100x19 spawning spaces. The other location i left untouched but wrote down the coordinates, the place has a 19x76 area where wither skeletons can spawn. If anyone wish to make a wither skeleton farm at one of these locations i will help but i cannot build anything at that scale by myself. also, if anyone has any good wither skeleton farm designs, that’s be great since i have no idea how to make such a farm.
