System: You have entered Demon Slayer Canyon;
Song Jian looked at the hundreds of meters deep canyon before him, the sight of which seemingly endless, a hint of astonishment surfaced on his face. He found that the walls of the canyon were as smooth as a mirror, as if they were chopped out with a sword.
But who could leave such terrifying sword marks on the earth? Even the zenith of one's combat power at the third stage couldn't achieve this, making Song Jian suspect that this canyon could only be created by a sword strike from divine beings as spoken of in legends.
The entrance of the canyon was a long slope, with boulders scattered all over. Thirty-five level Flame Demons respawned here. Each was about the size of an average adult, with horns growing on their heads and a faint red flame burning all over their bodies.
