Acid Bolts are found in the Quarry Interior area: defeat the Lv. 11 Heavy Golem at the top of the Quarry, then loot the Iron Box and pick up Manual: Acid Bolts inside the small shed behind it.
Acid Bolts are an early crossbow option in Beast of Reincarnation, found after you push into the Quarry side of Ogouchi Buffer Zone. The pickup is guarded, so treat it as a short combat detour: defeat the Lv. 11 Heavy Golem, then strip the shed behind it before heading back to camp.

You need to reach Quarry Interior, then take the elevator near the train tracks up to the top of the Quarry. The enemy name shown in-game is Lv. 11 Heavy Golem, and it blocks access to the shed.
Clear the Heavy Golem first, then check both interactables in the shed: the Iron Box gives Acid Bolts, while the table pickup gives Manual: Acid Bolts.

Mistakes that block the Acid Bolts pickup
Manual: Acid Bolts is not bought from the Wandering Merchant. That merchant sells other manuals, including Extinguishing Sand, Bottle of Acid, Torch, Acid Arrows, and Fire Bolts, but this manual comes from the golem-guarded shed.
Quarry Path is only part of the route. Keep pushing through the Quarry until you reach Quarry Interior, then use the elevator south of the train tracks to reach the upper platform.
If the shed is still inaccessible or unsafe, clear the Lv. 11 Heavy Golem fight first. Standard Quarry enemies are not the gate for this pickup; the Lv. 11 Heavy Golem encounter is.
