Rui almost shook with surprise, for the figure had entered his sensory ranges instantly.
The old man resembled a caveman. His attire was fashioned from the furry pelts of several animals and beasts. On his shoulder was a large bunch of firewood that he held up with a single arm.
His hair and beard were frizzled and matted. He resembled an ascetic who had secluded themselves in the mountains for a long time.
Which he indeed had done.
"Master Gurren, I-"
"Not interested," The Martial Master walked past him into his hut.
"You don't even know what I'm about to say," Rui raised an eyebrow.
"You're here because you want to learn domain techniques," Master Gurren snorted. "You're here despite the fact that you have undoubtedly hurt that I don't teach. Which means you think you can convince me otherwise. I hate arrogant brats like you. Especially brats like you who broke the record for the youngest breakthrough to the Senior Realm. You must think you can do anything."
