Cloud Firmament World

Summary
After 500 years of the  'black hole' incident, the Federation Government decided to send experts through this black hole to discover its cause/origin. However, to their surprise they found a world whose Spiritual Qi and size was several times richer and bigger than Yan Huang, they called it Cloud Firmament World, its original Overlord was the Monster Race whose leader is the Ten Thousand Monsters Mountain. After its discovery Human Race wanted to establish cities but Monster Race didn't stay still, they declared war against Human Race. Although both sides have several King Realm Cultivators/Beasts, the Human Race got the upper hand thanks to its powerful high tech weapons, with them Human Race pushed Monster Race little by little until them got enough territory to develop. Since then Human Race and Monster Race keep fighting each other. 

Monster Race 's hate towards Human Race keep increasing because some Human Race King Cultivators kidnapped women from Monster Race and start having children with them so their descents have both Human Race's King and Monster Race's beast bloodline. The first example we get to know is when Xia Ping enters Yan Huang University and meets Zhong Yuan, descendant of the King Clan Zhou who has Wind Kangaroo bloodline.

At the beginning we only know about Human Race and Monster Race but later we meet the Sea Race, this race is the Overlord of the whole sea territory in Cloud Firmament World.
