The reason Chu You decided not to take over the town was because firstly, he hadn't had the opportunity to experience what it was like to sack a town and wanted to try something new. Secondly, looting the town would mean obtaining maximum benefits in a short amount of time, but it would cause irreversible damage to the town ecosystem; if he conquered the town, he would have daily income, but the earnings would depend on the development of the town. But there is no faster way to make money than looting. Thirdly, his Battle Demonesses needed to kill NPCs to increase their morale, which was very important. High morale could multiply the damage dealt by the Battle Demonesses and this was also something that any competent commander could not afford to ignore.
