"How do you know?" Feiyang took a deep breath and asked softly. "Later, he told me personally," Qiu Jing replied with a smile. "What does he want to tell you?" asked Feiyang with a frown.

Two black Se straight knives draw a series of black Se flashes and arc lights. These two black Se weapons, which are one meter long and five meters long, expose their sharp black Se fangs. When wielding the straight knives, there is not a trace of broken wind, and you can hardly see the luster of the blade.
