(Summoning-focused, alternate history, with an emphasis on the alternate setting and claiming dominion.)
(Note: The setting has also experienced the era of the Hundred Schools of Thought, so some of their works will appear in the story.)
This is a parallel world resembling the ancient Earth, where the East has already experienced several dynasties.
The nation ruling this land is currently called Yan.
The Yan dynasty has had twelve emperors, but during the reign of the young emperor, the country fell into turmoil. After the young emperor died, peasant uprisings broke out across the land.
In the end, Emperor Huan dispatched several ministers to suppress the rebellions. Unexpectedly, after putting down the local peasant uprisings, the generals sent to various regions kept their armies and grew powerful in their own right.
This situation persisted into the reign of the current Great Yan Son of Heaven, Li Gen. The regions now govern themselves and even go so far as to declare themselves kings. With no strength or resources to stop them, the Yan dynasty was forced to recognize their claims, and soon every faction was calling itself a kingdom.
Qi was established in the east.
Qin, Liang, and Yong were established in the west.
Shu, Jing, Changsha, Wu, and Yue were established in the south.
Yan, Zhao, and Tang were established in the north.
The territories controlled by the Yan dynasty lay in a battleground, across vast plains. All the perceptive people of the realm could see that the Yan dynasty was doomed to fall.
With war breaking out everywhere, an age of chaos began to unfold, ruled by the maxim, "The Son of Heaven is whoever has the strongest army and the finest horses."
And in Shu, the death of a king opened a new chapter.
Yes, unlike other fictional hegemony novels, the country starts with a weak country and domestic ministers are intrigued by each other.
