In the << Legend of Mortal Cultivation >>, the Cyclops was a unique race that lived in the Scattered Star Seas. They were abnormally tall and had immense strength.

The one-eyed giants had low fertility, so they valued bloodline inheritance very much and were very united with their clansmen. The purer the bloodline of the giants born in this race, the stronger their bodies and the higher their talent in combat.
