The dark golden flames were actually an ability obtained from Yating’s evolution. Possessing a physical body didn’t alter her characteristics as an entity made of energy. Thus, she was still able to change herself into a being of pure and rich light essence. In this state, she could fuse with any of Long Haochen’s weapons, temporarily becoming the soul of this weapon, and igniting that weapon to produce a great gain in power. Simply said, the weapon would get destroyed after a single use, unless its materials could endure the pressure of weapon soul such as Yating.
