Golden Lightninng Palace!
This technique allowed lightning warriors to rise in strength as it can gather valuable lightning into one's body. It takes place in Soul Room and is closely to one's heart.
The lightning pool that the lovers were now tightly connected was also being slowly absorbed into this palace.
Di Xun as Goddess Lightning would be able to swallow this lightning pool if she had wings. Unfortunately, the lady was yet in mortal ranks with her power as the wings are quite hard thing to achieve.
With the body and soul tempering along with the Golden Lightning Palace that is like replacement for her wings, Di Xun took the big step towards her winged state.
Then, Xue Ren who has plans to achieve highest rank with every attribute he is close to was also experiencing nice change.
