Chapter 721: Big dog, you're so well-behaved

"When you gaze long into an abyss, the abyss gazes also into you."

While Walker was using his psychic senses to keep an eye on William, relieved that he hadn't been attacked by any mutant creatures, William felt that the fight between Walker and Amy had ended too quickly.

Even Amy, as foolish as she was, couldn't be beaten. 

That was just pathetic.

Was that really the end?

Impossible!

Impossible!

Just as Walker was about to walk towards William, a thunderous roar suddenly erupted from the woods.

A 30-foot-long white tiger, like lightning, dashed through the forest, snapping numerous giant trees in its path.

In addition, dozens of muscular, fierce-looking gray wolves and swarms of strange snakes gathered towards them.

"Holy shit! What's going on?" Walker was stunned. Hadn't everything been calm just a moment ago?

How did they all suddenly appear?
