Chapter 2343: A Song

The water on the home planet of the Immortal Vampires was blood-red.

They arrived at the underground river after entering the hole. The water was not only redder but also stickier here. It had a faint bloody odor as if it had been formed from blood.

The river was complicated and had many branches. It was like a maze.

Cultivators without strong spiritual power couldn't get out of the river.

The river was made of sealed crystal rock. It was milky white in color, and there were streaks of spiritual light flowing inside. It was like a spiritual snake swimming inside, emitting white light spots.

Whoosh

Zhang Ruochen condensed his Saint Qi into a four-foot-long Saint Sword and slashed out.

The crystal rock was broken, leaving a meter-long and deep sword scar.

"How is it so strong? Lady Wind, what are these crystal rocks?" Zhang Ruochen asked.
