The revenge of the only survivor (1)

In the winding underground tunnel, a misty shadow was moving forward like lightning. It was as fast as a bolt of lightning.

Because of the backward flow of seawater, most of the underground passages were filled with seawater. Although there were some that were completely dry, they only appeared once in a while.

Special environments created special creatures. Upon entering, one would find that this was a world completely different from the outside world.

The sudden appearance of the shadow monster broke the silence.

Many of the monsters in the tunnel noticed something unusual. It seemed that something was charging toward their territory, but before they could react, a shadow had already flown past them.

Some of the ferocious monsters even tried to attack and intercept the shadow. In the end, just as they attacked, their bodies suddenly exploded into a cloud of blood mist.
