function onKill(player, target)
    local monster = config[target:getName():lower()]
    if not monster or target:getMaster() then
        return true
    end
   
    local storageValue = player:getStorageValue(monster.storage)
    --if storageValue >= monster.start then
        if storageValue == monster.count then
            player:sendTextMessage(MESSAGE_STATUS_CONSOLE_ORANGE, "You have already killed " .. monster.count .. " " .. monster.plural .. ". Report back to The Hunter in Thais.")
        else
            player:sendTextMessage(MESSAGE_STATUS_CONSOLE_ORANGE, "You have killed [" .. storageValue .. "/" .. monster.count .. "] " .. monster.plural .. ".")
        end
        if storageValue < monster.count then
            player:setStorageValue(monster.storage, storageValue + 1)
        end
    --end
    return true
end

i don't understand this part too
if storageValue < monster.count then
player:setStorageValue(monster.storage, storageValue + 1)
end

if storageValue < monster.count then
player:setStorageValue(monster.storage, storageValue + 1)
end

If player didnt kill defined monster count (this in table) then it will add killed monster to the killed count.
