How to set int value back to the original value after it been changed by a statement?

[marble monolith]

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local StoneHealthRemoverEvent = ReplicatedStorage:WaitForChild("StoneHealthRemover")
local stoneFolder = game:WaitForChild("Workspace"):WaitForChild("Stones")

StoneHealthRemoverEvent.OnServerEvent:Connect(function(player, toolDamageValue, target)
    local targetHealthValueInt = target:FindFirstChild("HealthValue")
    local newHealthValue = targetHealthValueInt.Value - toolDamageValue
    targetHealthValueInt.Value = newHealthValue
    if targetHealthValueInt.Value <= 0 then
        target.Parent = ReplicatedStorage
        wait(5)
        target.Parent = stoneFolder
    end
    print(newHealthValue)
end)

This is the server sided script

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local StoneHealthRemoverEvent = ReplicatedStorage:WaitForChild("StoneHealthRemover")
local stoneFolder = workspace:WaitForChild("Stones")
local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
local character = player.Character or player.CharacterAdded:Wait()
local rootPart = character:WaitForChild("HumanoidRootPart")

local function getEquippedTool()
    for _, item in pairs(character:GetChildren()) do
        if item:IsA("Tool") then
            return item
        end
    end
    return nil
end

mouse.Button1Down:Connect(function()
    local target = mouse.Target
    local equippedTool = getEquippedTool()
    if target and target:IsDescendantOf(stoneFolder) and equippedTool and equippedTool:FindFirstChild("DamageValue") then
        local equippedToolValue = equippedTool:FindFirstChild("DamageValue")
        print(equippedToolValue.Value)
        local allowedDistance = (rootPart.Position - target.Position).Magnitude
        if allowedDistance <= 10 then
            StoneHealthRemoverEvent:FireServer(equippedToolValue.Value, target)
            print(player.Name .. " Clicked on: " .. target.Name)
        else
            print("To far to be able to click!")
        end 
    else
        print("Player is not holding a pickaxe!")
    end
end)

And this is the local script

The reason i just can't hardcode the value back is because i got diffrent stones in a folder with diffrent kind of health values

It is prob something so simple i'm just stuck
