"Let's go to the Skill Hall first," Lin Yucha suddenly spoke up, reminding them. "You two sisters just got some advancement materials, right? With a tier-six Skill Hall, you can easily advance all your skills."
The two women looked at each other, thought it over, and agreed. After all, the benefits of advancing skills were far superior to not.
Initially, they had considered whether to advance all skills because they didn't have the energy to keep advancing everything continuously. Rather than doing so, it might be better to give up some, which would lessen their future burdens.
However, the two sisters shared the same thought process as Du You; they wanted to advance every skill and keep improving. Only by doing so could they ensure they had no weaknesses and maintain the highest motivation for improvement.
