Dual-Wielding Obsidian Doll

After leaving the Harem Tower, Kent went to the Servant Tower. However, unlike the other towers, this one had nothing unique. It was just a plain space where he could have built a city for his servants if he wanted to.

He didn't have the funds to build a city just yet, so he left a few minutes later and visited the Legion Tower. But, just like the Servant Tower, that place also required him to build a city or barracks for his legion.

Leaving there, he went to the Soul Tower.

"This place is really made for soul cultivation. Just breathing seems to affect my cultivation," Kent said, taking a long, deep breath that filled his mood with joy.

[This place boosts the master's absorption speed by 60% and comprehension speed by 80%. So you don't have to worry too much about your soul cultivation. After all, the more people you add to the tower, the stronger you get.
