What Godwin didn't know was that Simon wasn't superimposing multiple skills at once to control hundreds of swrods as that would only play into the hands of the enemy. Instead, he was using the [Thousand Sword Mastery], a Lost Ancient tier skill that he had evolved from the Normal [Sword Mastery] skill.
Normally it would be impossible for the [Sword Mastery] skill to evolve in that direction unless one was stupidly rich and foolish enough to practice with all sorts of swords. That's right, the [Thousands Sword Mastery] was a skill that was accidentally created by Simon when he was practising with all the swords in his [Inventory] like a madman.
That said, it was impossible for anyone to acquire the same skill by copying his actions, after all, even Simon himself did not know it but he was only able to create the [Thousand Sword mastery] because of the [Ga??????] and [Armoury].
