Sir. Lowell McClain's plans
At some faraway place from the outpost, Sir. Lowell McCain is looking at the leaderboard ranking. He naturally gave permission to Elder Thornton to allow Zack to participate in it. Unlike, others He naturally knows the content of the Star Tower. Since, it's Star Tower situated in barren land. It's not hard for him to collect details from his connections.
After knowing the content he felt amazed by Zack's performance. He clearly knows Zack's ability. "He can reach this far using only those two lightning methods. He is indeed talented, not worse than any fellows here." He sighed to himself. It's not that he doesn't want to give him any lightning methods. Sometimes it will become a hindrance if there are too many options to choose from.
