Chapter 290: Chapters 220-222: Wave Valley Five Rats_4

The Mouse Dragon was quite special; like natural mice, it fundamentally lacked combat abilities. Although the Five Brothers' Mouse Dragons were a kind of dragon, most of their abilities were assistive: such as Stealth, burrowing, flying, and speed... all used for escaping and evading. In war, combat had to rely on claws and teeth; however, mouse claws are not long, and their mouths are not big, making it hard to truly injure an opponent.

Fortunately, these five rats were not completely useless. Their sole combat ability was a toxic breath, and the subsequently evolved poison fog. Like Xin Yun's acid fog, it could be triggered instantly, although the affected area was somewhat smaller. It was still enough to envelop any opponent in a cloud of poison.
