Gao Yang had long ago told Glolov to help find a good artilleryman.
After hearing Uriyangko's words, Gao Yang was very interested and immediately said, "I've always needed a good artilleryman, but is the one you mentioned a full-time artilleryman, or a multitalented soldier? My needs now differ from when I first started. If he's just a full-time artilleryman, I'll have to regretfully pass, but if he's multitalented, then I must see his skills for myself."
After a skirmish with the Angel Mercenary Corps—though there was no full-scale war—Gao Yang had witnessed the power of mortar fire and had since wanted to find a good artilleryman.
