The Third Dynasty of the Ulunhil Dynasty was established on the ruins of the Second Dynasty Dynasty, with the capital of the Atrium, and the sphere of influence of the Third Empire of Ulunshire was only the area around the three parts of the East and the South of the old Ulunshire.

At this time, the Elven Empire had been established for 15 years, and when the 2nd Empire of Yurenhil fell, the Elven Dynasty inherited the political and technological legacy of the 2nd Empire of Yurenhil.

The monster tribe in the north separated by the river has become a group of small-scale tribes wandering in the mountains and jungles, but at the time of the establishment of the Third Empire of Yurenhil, the monster tribes close to the Third Empire of Yurenhil also gradually accepted part of the Yurenhil battle culture and the elven art and natural culture of the elven dynasty, and inherited and developed the two cultures, and gradually developed an independent culture different from the elven blood clan, and established dozens of tribes of all sizes, collectively known as the demon kingdom.

Around the year 1145 of the Sun, the Third Dynasty of Ulenchir fought with the elves for the Lamia region, a major food town, and the blood clan won a tragic victory and obtained the Lamia region. The elves retreated north to the Chuntang region again, and the troops and horses were strong, preparing to counterattack the blood clan again, and the demon country resold military weapons on both sides in this war, the rapid rise of the demon country, the rise of the demon country caused the deep jealousy of the elves and the blood clan, and the blood clan sent a secret envoy to the elf dynasty to prepare to attack the demon kingdom together, so in the next thirty years, they no longer attacked each other, and sent personnel to the demon country many times to make trouble, which made the demon country restless.

Around 1158 in the solar calendar, under the infiltration of the elven blood clan, the demon kingdom was unable to maintain a unity, and began to fall into civil strife, and the demon kings from all over the country fought against each other. And at this time, the elf fleet took the opportunity to go south, after decades of training and training, the elf dark court has begun to take shape, whether it is a frontal battle or a secret kill, the dark court has shown strong strength, and the prepared elf team and the blood army occupy more than half of the land of the demon country in one go.

Around the year 1232 of the Sun, the Blood Clan defeated the Abyssal Race and concluded the Covenant of the Abyss Race with the Abyss Race. At this time, the eastern region of the Elven Dynasty began to rebel, and the barbarians used troops against the elves, aiming at the advantages of the elven woodland, the barbarians set fire to destroy the forest in batches, and the barbarian cavalry was invincible in the wasteland that opened up with the smell of trees and embers, and the main force of the elven army, including the four strong brigades, was almost wiped out by the barbarians. The smoke from the burning forest shrouded the eastern part of the country for eight years, and it burned the eastern part of the Elven Dynasty into a vast Gobi.

In the year 1258 of the solar calendar, the only female emperor of the Bloodline Dynasty appeared, and her rule achieved a brief military revival of the Blood, and during her reign, the Bloods took advantage of the fire in the east of the Elven Dynasty to tear up the Elven peace treaty and launch a surprise attack.

In 1261 of the solar calendar, the unification of the blood clan and the elven dynasty won, Korqin ascended the throne as the emperor, and changed the name of the country to the Third Empire of Ulunhil. However, Zhongxing only lasted for two generations, more than 50 years later, Horqin's grandson ascended the throne, Sacco had great ambitions but no talent to govern the world, when the Kraken was in chaos, Sak poured all the power of the world, did not have an inch of land, and ruined the foundation of Horqin's painstaking management in vain. This also made the princes support their own troops, and the royal power was gradually hollowed out.

In the year 1311 of the solar calendar, the Third Dynasty of Urunhil was once again mired in civil strife, and the great kingdoms fought against each other, and political power overlapped.

Around 1355 in the solar calendar, Ptolemy, Grand Duke of the Blood Clan, invaded the Apocalypse, and the Fourth Empire of Ulenhil was established.
