The unknown assailant's attacks consisted out of punches. Xin Feng could clearly tell that they were punches due to the sensation similar to fists hitting his face.
With the shock waves that each punch released, Xin Feng was able to tell what the figure looked like as well. The figure was some type of low-ranking demon, obvious from the fact that it looked similar to the demon lord but was actually smaller and less intimidating.
The demon never stopped punching, and because of it not stopping, it was wide open for any attacks. It was so determined to continue punching Xin Feng, that Xin Feng was able to grab its throat easily. Its attitude was completely different to before when it was still lurking around.
The moment Xin Feng grabbed on the demon's throat, he threw her to the ground, using all of his strength, and right after, he continued slamming her until he had broken all of her bones including her neck.
