Chapter 1005 One Shot to Win

'I still can't believe that I made this thing.' 

From out of his item box, Marcus had pulled out a giant adamantine tube that was around twenty meters long. Though, while it was incredibly long, the thickness of the adamantine was only around a quarter of a centimeter.

During his most recent stint of crafting Marcus had gotten a bit carried away and made this weapon that was quite impractical.

It was meant to increase the power of his railgun spell to the upmost limit, but the giant adamantine tube was unwieldy and could only be fired once before the enchantments became damaged and needed extensive repairs.

Nevertheless, Marcus knew that this weapon was the only thing he possessed that might possibly be able to produce an attack that could pierce through the barrier around The Celestial Seven-Headed Serpent's central head.
