At that time, the Second Empire of Ulenhil was in a period of prosperity, with all races living in peace and contentment, cultural and economic prosperity, and during this time, poetry, painting, music, and dance were flourishing. Cafes, wine halls, and cabaret bands have sprung up like mushrooms.

At this time, the Second Empire of Yulunhil was mainly active in the western part of the Holy Demon Continent. Around the year 485 of the solar calendar, the power of *er gradually penetrated into the border of Yurenhil, and the border friction between the two empires continued, and the border disputes and the resulting caste revenge led to the increasing friction between the blood tribes, which gradually evolved into a skirmish.

Around 500 years of the sun, a small border country found excellent iron ore, and to create sharp tools, the metal tools they produced were spread into the Yurenhil Empire, the first to touch the metal tools of Yurenshire quickly recognized the potential value of iron in the war, after painstaking research and development, Yurenshire army occupied the small border country, mastered the smelting method of iron, and began to use metal weapons on a large scale, thus achieving a great advantage in the war, and gradually annexing the surrounding small countries.

In the year 526 of the solar calendar, when Urenhil defeated most of the southern countries, the great chief of Urenhil proclaimed himself emperor and said that all the land where the sun and the moon shine is the territory of Yurenshire, showing great aggression.

In 582 years of the Sun, the Yulunhil Dynasty adopted a system of relative centralized power, absorbing the lessons of the previous dynasty, and assigning his brothers to various places to guard the eight directions for himself. In charge of other regions, the local county king retains his own army. And some of the former vassals of the defeated kingdoms were unwilling to submit to the rule of the Yurenhil dynasty, and they took refuge in the north.

In order to unify the eastern region in 612 years after the solar calendar, the army of the Yurenhil Dynasty entered the northwest of the *Er Empire under the leadership of merchants, and thus discovered a fertile basin that extended almost infinitely to the south. As a result, Yulun Hill also formulated a policy of immigration and settlement, and stationed nearly 500,000 elite troops here, all of which were kept in the dark.

Around 635 years in the solar calendar, after 20 years of governance, the benefits of the empire's conquest of other countries have gradually been imagined, the Coritia granary in the north of the Yurenhil Empire, the ordnance factory in the south, the shipyard in the lake area, the textile factory in the Cecilia region, and the commerce in the Valmi region, the increasingly prosperous Yurenshir has gradually caught up with and surpassed the * Empire in terms of population and urban development level with his great charm, and the blood population is close to 100 million, more than twice as much as at the beginning of the century ago. Yulun Hill set up an atrium, and so far, the political, economic, and military centers of Ulun Hill were all transferred to the middle court.

Around 653 years in the solar calendar, some of the Guixi tribes of the *Er Empire who had lost power moved eastward to the Xingbei region, where they established a number of nomadic tribes, and gradually merged into the four major tribes of Xinghe, Dachi, Miluo, and Yuanfu in the following hundreds of years.

Around 685 years of the solar calendar, a group of Yulun Hill went north, and was stubbornly counterattacked by Yanbei Lixi, who relied on geographical advantages, with the terrain advantage of the woodland, but was finally defeated, and the capital of the northern part of the blood clan Yan was captured. Yanbei had to accept the humiliating treaty and join the Yulun Hill Dynasty in its entirety, and pay tribute to the Yu Lun Hill Dynasty. Subsequently, Yulunhil launched an expedition to pacify the country, in order to completely surround the escape route of the *er Empire, the blood clan army with an absolute advantage in the number of troops and the well-equipped and skillful defense of the pacification country launched a long and fierce battle, the pacification country launched a difficult battle to defend the kingdom with the support of the *er Empire, in which the capital of the kingdom fell many times, and was recaptured many times, the high-level of the Yulunhil Empire believed that this was a bloodletting operation, and it was necessary to rely on this war to wipe out all the elites of the *er Empire here.

In 695 Sun, the ten-year war finally ended in the victory of the Yurenhil Dynasty, and Yurenhil fulfilled his promise to bury the elite of the *Er Empire here, and according to the internal statistics of the *R Empire, a total of 260,000 troops were buried in the territory of the pacification country.

In the year 700 of the solar calendar, Ulunhil finally tore off his disguised face and unabashedly expressed his desire to invade, and Urenhil attacked the important town of the *er empire for no reason, and the other army of Yurenhil hidden in the territory was also sharpening its knives, ready to cooperate with the outside at any time, and insert a knife in the heart of the *er empire.

After the year 703 of the solar calendar, Emperor Ulunshir waved his army to the northwest, and the imperial army had been confronting Ulunshir on the edge of the ancient demon region for 3 years. Battled by war, Yurenhil soon advanced his offensive deep into the hinterland of the Ancient Demon Region. The decisive battle in the Ancient Demon region ended in the victory of Yurenhil, and the army fled in a hurry and marched towards the capital area, but they finally gave up resistance when they saw the flag of the Yurenhil Empire flying above the imperial capital.
