"So be it,"
Li Qinghong, having been in seclusion for quite a while, was ready to stretch her muscles. Smiling, Li Yuanjiao nodded and stepped back.
Her face broke into a smile, and with a flick of her spear, she spun a beautiful spear flower that shimmered with purple light. Li Qinghong didn't engage in a spell battle using thunder light on the lake; instead, she first used the Water Manipulating technique to approach the catfish demon a few steps at a time.
Thunder Dharma differs from Sword Qi. Sword Qi is "the sharp energy formed by the emanation of metal", and it doesn't conflict much with aquatic creatures; the energy loss from piercing through the water is minimal.
On the other hand, Thunder Dharma is "thunder attribute, also fire, the vital energy of Yin Yang with Yang in excess becoming thunder," if released underwater, naturally, it wouldn't be ideal.
