After Zhang Mengyao, the other girls followed his advice to get more defensive skills. It was not that they lacked defensive skills, but they didn't have a passive defensive skill that was active all the time. It was a skill but also an armor at the same time.
Dispersal and Energy Shroud were the most important defensive skills in Tang Shaoyang's opinion. That was like armor for him. Dispersal would reduce the incoming damage, and Energy Shroud acted as armor and a shield.
Kang Xue, Ashley, Rosalie, Liang Suyin, and Lunea bought those two skills. Just like Zhang Mengyao, they also bought two more defensive skills. Rosalie and Liang Suyin were fire elementalists, so they picked the Flame Shield, one of his skills that he rarely used lately.
The Flame Shield would launch a counterattack in the form of fire once it was broken. It fit them because their fire was strong. The counter would be stronger.
