Ultimate Skills

Duere couldn't be blamed for thinking he could outlast the twins and Kentucky. He wasn't the first one to fall for this trap, either. Rean and Roan's Yin Yang Cultivation Technique allowed them to have Dantians capable of storing over three times more energy than experts of the same level.

This incredible advantage had its own drawbacks. For example, the twins always needed several times more energy to cultivate a single realm than anyone else. Fortunately for them, Rean was really, really good at earning Spiritual Stones, so they never truly had to worry about the lack of energy. Even when they came to this planet, the twins barely met this kind of problem. Let's not forget the fortune the twins did back in the Sunlight Realm as well.
