help a brother out

forgot to save it and its not in my history anymore :(( its a bl (i think?), the mc got isekai-ed into a gacha game. the way the game works is you pull heros and then use them to fight monsters, complete dungeons, etc. (the heros are from the past i think, so theyre technically dead). the mcs first hero was a blond hero who for some reason cant remember his past, and he didnt have a weapon when he spawned so he had to use a shovel lol. there were a few scenes where the mc was trying to figure out the hero's abilities and their cooldown times by running tests. oh and there was a sheep
theres more lore stuff i remember but idk how to explain it without it being confusing
