"Undead dog, you're so f*cking unreliable!" Lin Qi said loudly as he rode on the Dark King's back.
"Don't push it, they're almost catching up!" Dark King ran without looking back.
Lin Qi and Dark King were followed by a group of rats, densely packed together.
They were mining rats that specialise in finding and feeding on metallic minerals. Their two front teeth could easily bite through hard rocks.
Mining rats had individual strength of only three stars, but they were numerous. Moreover, their reproduction rate was high.
On the fifth day after mating, the mother rat would release the immature mouse eggs into the metal minerals through the outer navel on her stomach.
That not only saved the time to conceive, but it could also increase the number of mouse pups. Generally, a single birth could give 20 pups.
With such numbers, even a five-star devil beast would have to temporarily avoid them.
