The Oracle was still acting behind his back, and actually, Gremory didn't care that much anymore. The Witch somehow managed to find a mine of mitre, and that alone was wonderful.
He could do all kinds of experiments using it, boosting his knowledge over the runes of tier four by not caring about the resources anymore, and the best thing, he could build a proper army with a mine.

After reaching rank S, Gremory finally started to see things differently by using Hanzor constantly as he is using now. He also discovered that if he imbued his mana as an electric current and released it to the environment, it could be used as echolocation. A radar that only detects living beings since the only obstacle for energy is another kind of energy.
Nevertheless, anything carrying energy could be detected by it, and Gremory decided to call it "Ping".
