When Klaus first saw Fruity form his Star Core, he figured it would be a literal core, like an egg or something. However, he was mistaken.
The core that formed was just like his soul sea, only stronger and wider. It was as if a small river had suddenly become a vast sea.
So, when the senior told him he'd have to form each core one at a time, Klaus knew he was in for a challenge. But for now, he could only relax and focus on other things. He'd be going to the academy in under two months.
From what he knew, the academy had no shortage of resources, so Klaus knew he would get the support he needed, even if his nine qi seas threatened to drain him. At least he wouldn't be handling it alone.
"Anyway, Senior, what can you tell me about the sword skill I used to kill the gatekeeper? Also, what happens now that I killed it?" Klaus asked, wanting to switch topics.
