The Canglan Continent has vast land and rich resources, and the human race and the beast race live together on this continent. Since the birth of the mainland, there have been constant wars and flames.

After thousands of years of evolution, this continent now has five masters: the beast tribe living in Liaozhou, the far east; Xianbei Hu, who has the vast grasslands of the north; Sitting in the center of the mainland, there are Liangzhou, Yongzhou, Sizhou, Bingzhou, Jizhou, Youzhou, Qingzhou, Yanzhou, Yuzhou, Xuzhou and Yizhou. Located in the rich south, there are Yangzhou, Jingzhou, and Jiaozhou Yucang Federation; and Wakoku, a maritime country with many islands.

The living environment of the orcs is extremely harsh, it is a bitter cold land, so they have a strong physique and ambition that are different from the human race, and they are often enemies of the human race. However, due to the limited strength, and the surrounding Xianbei Hu and the Celestial Star Empire, they also had to huddle in the extreme east.

In the third year of Yuanzhen, the orcs invaded the Celestial Star Empire. But just when their soldiers approached Yuguan, which is known as the "first pass in the world", they were resisted by Ling Tianlei, the emperor of the Tianxing Empire, and returned home, but unfortunately Ling Tianlei also died of a violent illness a few days after the war.

After the Battle of Yuguan, the situation between the Beast Clan and the Celestial Star Empire has changed a lot. Caesar, the eldest prince of the beast clan, usurped the throne and became the new beast king, and the throne of the Celestial Star Empire was inherited by Ling Tianlei's brother Ling Tianmu, the king of Liang, because Ling Tianlei had no heirs.

After Caesar became the king of beasts, he ruled the country internally, enriched the country and strengthened the army; Externally, he was friendly with the Celestial Star Empire and Xianbei Hu, and put on a weak posture, calling Ling Tianmu, the new emperor of the Celestial Star Empire, and Xianbei Hu Dadan Yu Wenpo as brothers, and himself as brothers.

After Ling Tianmu inherited the throne, in order to pretend to be a gesture and show his virtue, he first posthumously crowned the former emperor Ling Tianlei as the "Shenwu Emperor", and the temple name "Emperor Wu", and then followed the policy and year name of the Ling Tianlei period, and served Mu Yin, the empress of the Shenwu Emperor, as the queen mother and so on. And only half a year later, the Empress Dowager Mu Yin died of depression and illness, and then Ling Tianmu revealed his true nature, wantonly promoted his cronies, suppressed the old ministers during the Shenwu Emperor, changed the policy of the Wu Emperor period, promoted literature and suppressed the military, and set the era name as the Apocalypse, determined to create his own prosperous and prosperous world.

Fifteen years after the Apocalypse, the empire has long since lost its former strength. The civil officials above the court are corrupt and corrupt, and they are full of benevolence and morality. The military generals were suppressed, and the imperial army was gradually controlled by civilian officials, and the morale was getting worse day by day, and the combat power was getting weaker and weaker.

At this time, the orcs saw the opportunity, tore off their hypocrisy, and fought against the Celestial Star Empire without declaring war, and attacked Yuguan with all their army. When the Celestial Star Empire got the news, the court was terrified. The empire has enjoyed peace for more than ten years, and the wars on weekdays are all small fights, when has there ever been such a big scene.

Fortunately, there are also the three princes of Prime Minister Bai Hua, Taiwei Yan Qin, and Imperial Historian Luo Qi above the imperial court, they first played to let the emperor Ling Tianmu gather an army, and fought back in Yuguan, and then urged him to drive the expedition in person, with strong morale, Ling Tianmu happily accepted it.

Finally, after a hard fight, the Imperial soldiers repelled the attack of the Orcs. At this time, in order to complete his work in one battle, Ling Tianmu ignored the advice of many ministers and ordered to chase down and defeat the fleeing orcs.

When the imperial army chased to Montenegro, Xianbeihu's army suddenly appeared in the rear, and under the front and rear attacks of the orcs and Xianbeihu, the imperial army was crushed by a blow and was almost completely annihilated, and only a few people fled back. At this time, the monarchs and ministers of the Celestial Star Empire came to their senses, and it turned out that the orcs had already joined forces with Xianbei Hu.

The Battle of Montenegro changed the long-standing situation on the Canglan Continent, after which the orc army captured Yuguan and marched all the way from Youzhou in the north of the Celestial Star Empire, as if no one was in a no-man's land, and Xianbei Hu also launched an attack on Liangzhou in the west of the empire. The Japanese also took advantage of this to make trouble, and frequently appeared in the Qingzhou area to plunder.

By the seventeenth year of the Apocalypse, the Celestial Star Empire had been weakened, and only Yizhou was left after being beaten by Xianbei Hu and the orcs. The empire could only rely on the dangerous terrain of Yizhou to survive.

After capturing Yongzhou and dividing the territory of the former Celestial Star Empire with the orcs, Xianbei Hu gathered troops non-stop to attack Hanzhong of the Celestial Star Empire, and the barbarian Haoqiang in the southwest of Yizhou rebelled against the empire at this time, and the Celestial Star Empire, which was already struggling, fell into a desperate situation of internal and external difficulties.
