Making a fireball pierces through enemies

[Sonix_LA]

I’m making a tower defense game so I want to make a tower that throws a fireball that pierces enemies.

1. What is the issue?
   I’m using a module script to make the shoot system and once the fireball hits its target it destroys itself but I want it to just pierce the enemy and continue on its way for a couple of seconds (in the same direction) like this:
   

   
   
   (that character at the left is my tower and that thing at the right is the fireball)

2. What solutions have you tried so far?
   I tried to set a position a little further from its target, like target.Torso.Position.X + 50, but it keeps going to a specific position and not in the target direction.

This is my code:

local p = Instance.new("Part", workspace)
p.CFrame = CFrame.lookAt(newTower.Gun.Position, Vector3.new(target.HumanoidRootPart.Position.X, newTower.HumanoidRootPart.Position.Y, target.HumanoidRootPart.Position.Z))
p.Anchored = true
p.Shape = Enum.PartType.Ball
p.Material = Enum.Material.Neon
p.CanCollide = false
p.Size = Vector3.new(1.65, 0.35, 1.65)

-- here is where I have problems
local newPos = Vector3.new(target.HumanoidRootPart.Position.X + 50, newTower.HumanoidRootPart.Position.Y, target.HumanoidRootPart.Position.Z)
local TweenService = game:GetService("TweenService")
local pTween = TweenService:Create(p, TweenInfo.new(0.85), {Position = newPos})
pTween:Play()

(btw, newTower.Gun is the neon ball of the tower)

If anyone can help me please, thanks!
(this is my first post in the forum btw)

use units to off set it furthuer

local newPos = target.HumanoidRootPart.Position + (target.HumanoidRootPart.Position + newTower.Gun.Position).unit * 20

It works now, thank you so much!
