At first, each of their attacks could force the zombie dragon back dozens of meters or more, but now their strength gradually failed to shake the zombie dragon.
The first Ning Tianlang swung his fists like raindrops, casting multiple illusions in front of him, as if he'd grown more than two hands.
The second Ning Tianlang's sword, not to mention the speed at which it was swung, clearly showed a tight sequence of attacks from the fog-like blade light in front of him.
Roar!
At that moment, the zombie dragon suddenly let out a low roar, and the sword embedded in its head plunged deep into the flesh and disappeared. The next second, with a swish, the sword spat out from the zombie dragon's mouth!
The first Ning Tianlang had no time to react before the sword struck him squarely in the chest, sending him flying backward, coughing up fresh blood.
