There's a reason why intelligent beings started to use tools.
They were useful as an extension of people's natural power. In a lot of cases, they could amplify people's power, and make people capable of doing so much more.
And that was why I used Alveitya now, instead of purifying the land with just my body as a medium. One, I found out that using Alveitya's spear mode concentrated my absorption into one point; the spear's tip. Just like Amarein taught me, it was safer, and I could control the amount coming into my body better.
Right; like drinking using a straw--however ridiculous it might sound.
