Yan Lie slashed out with his two sabers, causing sparks to fly. With every attack, there was an explosive sound and dust flew. However, there were no enemies to the naked eye. Yan Lie seemed to be fighting an invisible object.
Almost instantly, Xu Tui's mental perception discovered Yan Lie's enemy.
It was a one-meter-long creature with six limbs. It was dark red in color, exactly the same color as the ground of Mars. Even the changes in the light and dark were exactly the same, causing it to be completely invisible to the naked eye.
However, during the battle with Yan Lie, there would occasionally be flashes of energy and flashes of metal. There was no change in the temperature on his body. There was only a dense stream of energy.
Mechanical Spirit Race!
This was the Mechanical Spirit that Instructor Lu Kang had called the Mars Remnant Poison.
