After discussing with the others, Jack chose to research University. He paid 15,000 gold coins and 10,000 mana. The research itself took 25 days to complete.
Jack could use his Ruling Power to hasten the research time. one Ruling Power reduced the research time by ten days. But Jack didn't want to waste his ruling power, he wanted to save them for using Mass Drill again next month.
Jack turned to the next research tree, the Military Path. This path also branched out from a single tech and went up multiple lines along already researched techs until it ended with four available techs that could be researched.
The four were Explosives, Propaganda, Rapid Arrows, and Drilling Thrust.
"Hey, Drilling Thrust? Isn't that the name of my skill?" Jack asked.
"Yes, it is a battle skill. Once you researched this tech, all melee units with piercing weapons could choose to learn this skill in fighting schools," Peniel explained.
