Lightning Is the Only Way

Under his father's directions, Gravis named a lot of different materials and their properties. Though, since he didn't understand the underlying concepts, he could only quote what the booklet had said. One could argue if being able to recite all of this information was knowledge or not. After all, he didn't understand the deeper meaning of the materials. He could only quote something.

Gravis only knew the what, but not the why. Yet, a vast sea of what was required to understand the why. There was no way around this. After Gravis had recited the different materials and their properties for around two hours, his father grabbed a piece of ore.

"Look," he said.

BZZZZ!

A purely white bolt of lightning appeared and enveloped the ore in the air, and Gravis immediately felt the familiarity with this lightning. It was Punishment Lightning, the same lightning Gravis had. Yet, Gravis wasn't really surprised that his father could use such lightning. His father had also said in the past that people generally understood this lightning further down their cultivation path. This meant that there were a lot of people able to use it.

As the material floated in the air, the lightning bathed it, heating it up quickly. After a while, it started becoming malleable. Gravis knew the specifics of the material, so he knew how much power his father was using. On top of that, due to his affinity towards lightning, he could also feel the power with his being. It wasn't very strong. Gravis could create such powerful lightning without any issue.

Slowly, the ore started taking the form of a standard sword. After around three minutes, it had completely taken the shape of a sword. Yet, it didn't have sharp edges.

"You need to use your Spirit to form the material into a weapon," his father said. "It's quite a bit of stress on your Spirit and concentration, which is where your concentration training comes into play. You need to keep the finished product's shape in mind and use appropriate force with your Spirit. Too much, and you might damage its composition, too little, and it will break."

Gravis nodded as he kept looking at the sword-embryo.

"The edges of a sharp weapon need many times more concentration than just creating the weapon-embryo. When the material is much weaker than your current Realm, you can simply force it."

SHING!

In nearly no time at all, the sword's sides compressed, forming a very sharp cutting edge.

Whoop!

with such weak materials, you only need to force the borders of the sword into a sharp edge. At that point, depending on what material you used,
