Capítulo 355: Upgrading My Soul Class

"But… How can I do that? And how will that help me exactly?" I was surprised to hear that from him. After all, I killed lots of humans before, but never got to store their souls.

Even when I killed traitors, they didn't end up as a separate soul in my soul list. I never thought about this before. After all humans were that kind of race that wasn't good at any battlefield.

Yet per his words here, it seemed I was wrong, partially.

[He says that having human souls are essential for your road map for cultivation. You are killing a ton of humans now, so it's a waste to not use this chance to do this. You have to upgrade your soul class two stages in a row. The next stage of your class is called soul merging. It's aiming to merge souls to make a stronger one. The next stage will be the soul evolution, which will enable you to upgrade any soul you have stored before]
