Shuang'er should be able to have six effects in total, but it currently only has three effects or powers.
The remaining three effects were still in the blank state, and Tang Li Xue had to find a rare, precious material with a powerful special effect for Shuang'er to absorb.
After absorbing that rare, precious material, Shuang'er should be able to obtain the power or characteristic from that rare, precious material.
There were actually many rare, precious materials stored in the [Nine Elementals Immortal Pagoda], which Tang Li Xue obtained from various sources, such as Grandmaster Nie Jun's inheritance, the Great Wei Dynasty's imperial treasury, and so on.
All of those rare, precious materials were good, but unfortunately, Tang Li Xue felt that they were still far from good enough for Shuang'er.
Tang Li Xue was not in a hurry since Shuang'er's three effects, [Soul Obliteration], [Thunder of Destruction], and [Thunder Sword Domain], were already extremely powerful.
