After that, Sun Tianqi looked at everyone, took out a map from his backpack, and after unfolding it, the words on the map of the migration map of the ghost country were clearly visible.

He picked up a ruler and pointed to the map and said: "This is the map of the territory of the Yin Shang that I have asked Western scholars and domestic literati to restore, at that time, beyond the northwest limit of the Yin Shang was the Guifang country, and the activity area of their Guifang tribe was probably in today's Shanxi, northeastern Shaanxi, central Mongolia and the two banks of the Yellow River, belonging to a semi-nomadic and semi-agricultural ethnic group......

As early as before Shang Tang destroyed the summer, the ghost country already existed, at that time the main part of the ghost side lived on the grassland, was a nomadic people living by water, until the end of the Xia Dynasty, the cold in the north intensified, the grassland did not grow a single grass, the ghost country people for survival, began to migrate south, and gradually came to live on the Shaanxi Plateau.

At that time, the Shaanxi Plateau was not the barren state of today's loess slopes, at that time the water and grass were abundant, the vegetation was dense, and it was an excellent habitat, enough for the ghost people to survive, if there was any bad point, it was too close to the Xia Kingdom.

When they were far north of the Yellow River, there was still a long distance from the Xia Kingdom, and there was a barrier from the Yellow River, so it was naturally not easy to have contradictions, and after migrating to the Shaanxi Plateau, it was not far from the border of the Xia Kingdom, and if there was no buffer between the two countries, there would be constant contradictions.

Since the Yan and Huang eras, the Xia State has always occupied the Central Plains terrain as a precious, calling itself the Central Plains Dynasty, facing the people in other regions, usually regarded as barbarians, Dongyi, Nanban, Xirong, Beidi, there is always a contempt that can be applied to it.

After the Ghost Fang people approached the border, they became a member of the Xirong, because the soldiers were extremely cruel and wore ghost faces, they were called the Ghost Rong people by the Xia Dynasty, and they were the biggest enemy threatening the security of the Xia Dynasty in the northwest direction.

By the end of the Xia Dynasty, the ghost Rong had gradually unified the Rong people in the northwest and began to covet the land of the Xia Dynasty.

The Xia Dynasty lost nearly 10,000 troops for this, and until the Xia Dynasty was destroyed by Shang Tang, they did not solve this northwest threat.

After Yin Shang destroyed the summer, Shang Tang made a decision to kill, and forcibly used the lives of tens of thousands of soldiers to kill the main department of the ghost party, and only the old, weak, sick and disabled returned to the grassland.

On this basis, Shang Tang completed the great cause of consolidating its territory, bringing peace to Yin Shang for hundreds of years, and also making Fang Guo in the northwest region realize the strength of Yin Shang, and never slack off when he sees Nagong every year.

At the same time, the ghost people fled to the grassland and suffered a great defeat, and what awaited them was a lack of food and clothing in addition to the bitter cold illusion.

They have been away from their homeland for hundreds of years, and they have long been accustomed to the wealth of the Shaanxi Plateau, and many ghost people are like outsiders, becoming more and more unaccustomed to the water and soil, plus they escaped this time, completely afraid of Yin Shang's unscrupulous killing, the resentment in their hearts can be imagined, and the idea of retaking the Shaanxi Plateau in the ethnic group is becoming more and more prevalent.

They knew that the strength of the Ghost Fang Kingdom was no longer enough to compete with the Yin Shang Dynasty with the rising red sun, and they began to recuperate on the grassland.

More than 100 years later, Shang Wang Zhongding canceled the primogeniture inheritance system, which directly led to the rebellion of the Nine Dynasties, and the Xirong tribes, which were originally located in the northwest, began to take advantage of this opportunity not to meet and not pay tribute.

Due to the chaos caused by the struggle for power among the local princes of Yin Shang, the defense of the northwest region was empty, and before the people of the court could react, the Guifang Kingdom had already crossed the Yellow River and came to the Shaanxi Plateau again.

This time, they continued to plunder southward, from the grassland to the Qinling Mountains, all of which were occupied by the Ghost Fang and established the Ghost Fang Kingdom.

Judging from the territory map, the territory of the Guifang Kingdom is shaped like a long snake, directly connecting the grassland and the Qinling Mountains, and extending to the Hexi Corridor, almost completely blocking the northwest boundary of Yin Shang, as long as Yin Shang wants to expand westward, it is inevitable to have conflicts with them.

The ghost people had this intention, as long as the Yin merchants wanted to expand their territory, they just took the opportunity of the Yin merchants to invade their territory and sent troops towards the Yin Shang mainland, vowing to reach the outside of Chaoge City.

At this time, because of the Zhongding Rebellion, the Yin Shang had already weakened, and the internal and external troubles continued, barely holding the southern and western frontiers.

The Yin Shang royal family knew this, no matter how chaotic the dynasty was, they were not confused, and they never easily started a war on the border, and the ghost people saw that they were determined not to move, so in order to start the war as soon as possible, they had to deliberately plunder the people on the frontier, and also united with the Fang State in the northwest to kill the Shang courtiers, so as to provoke the Yin Shang Dynasty to take the lead in the war.

For so many decades, the Ghost Fang Kingdom has never succeeded, and the Yin Shang royal family has endured humiliation for decades, and finally waited for the time to raise their eyebrows!

After Wu Ding succeeded to the throne, he personally led Wang Shi to the northwest, killed the ghost people and retreated dozens of miles, and no longer dared to compete for power, and even, he did it more ruthlessly than his ancestor Shang Tang - Shang Tang just expelled the ghost people to the Mobei grassland, and he directly used the strategy of differentiation to completely separate the ghost nobles and the people.

Since then, the ghost fang clan has changed from nomadic to settled life, and the ghost nobles have also been canonized as nine surnamed ghost marquis by Yin merchants, and they have been assimilated to the end, and they will no longer be wild in their ancestors.

Until two hundred years later, the Yin Shang Guozuo came to an end, and the nine surnamed ghost marquis in order to avoid trouble, since then incognito into other tribes in the northwest, only some of the ghost people felt the call of the ancestors of the ghost side, came to Shennongjia outside the border of the Yin Shang country, and disappeared since then, and there is no history to record them.

Yue Guanchao and the others listened to Sun Tianqi's introduction, which was probably the same as what they guessed, in conjunction with the territory map of the Yin Shang period of the Ghost Fang Kingdom, they could clearly see the changes in the territory of the Ghost Fang people, but there was one thing they didn't understand very well.

"Ghost people, how can they hide in Shennongjia, some people don't return to Yin Shang, shouldn't they go back to the Mobei grassland?"

Although they had already guessed that the ghost people were hiding in Shennongjia in order to avoid Yin Shang's killing, they still felt that hiding in Shennongjia was a little too deliberate, as if they had deliberately found such a place.

Sun Tianqi coughed a few times: "I think it's because of natural disasters and man-made disasters, at that time, most of the people of the ghost side went south or there were natural disasters, after being pacified by Wu Ding, most of the people of the ghost side have returned to the Yin Shang, only a small number of people are unwilling to live or die, long-term migration requires a large number of people to maintain the rear grain and grass, this part of the people is unlikely to have the ability to return to the grassland, according to Wu Ding's meaning, if they do not recognize the rule of Yin Shang, then they are not the people of Yin Shang, and they cannot stay in the territory of Yin Shang." ”

After that, he pointed to the southwest on the map: "The homeland of the Guifang Kingdom is basically from Shanxi, northeast Shaanxi, central Mongolia and both sides of the Yellow River, which is equivalent to directly blocking the national boundary of Yin Shang's expansion in the northwest from the northwest. ”

"After the people of the Ghost Fang Kingdom are attached to the Yin Shang, these places will also become the Xinjiang territory of the Yin Shang Kingdom, and some of the Ghost Fang people who do not want to belong to the country probably have only three choices, either continue to cross the Hexi Corridor to the west, or return to the northern grassland, or go south to find a new land."

Sun Tianqi continued: "Among these three different paths, because there are too few remaining Ghost Fang people, it is basically impossible to return north, if you go west, you can only occupy the Hexi Corridor, and the farther away will become a desert, and it is easy to be trapped and die in Hexi, then, the only feasible thing is to go south." ”

He knocked the ruler on the southwest position, and his tone became mysterious: "At that time, the southernmost boundary of the Yin Shang was near Jianghan, and the south and southwest of the wide area belonged to the land of smoke and miasma, and the Yin merchants were not willing to go to the southwest at all, and in addition, the Chiyou tribe also escaped into the southwest after the defeat, which made the southwest even more dye the color of horror and mystery, for the Yin merchants, the land of Sichuan and Shu only had the existence of the ancient Shu Kingdom, but because the Shu road was difficult to climb, there was no communication with the Shu people, and they were too lazy to conquer and unwilling to bother. ”

"There are very few places that the ghost people can choose, and I am afraid that the only places they can choose are the plains near the river, that is, those places in the Jianghan Plain, if it is in the plains, it is easy to be noticed by Yin Shang, I guess that they entered Shennongjia because they found something in Shennongjia, or they simply did not want to expose the group to danger anymore, and wanted to rely on the primeval jungle to cover the whereabouts of the group, which can also be explained."

Yue Guanchao listened to Sun Tianqi's introduction, and was sure in his heart that he was indeed not lying, they had already heard Sun Daqiao mention a few words about these news, and probably guessed what the ghost Fang clan was, all this just now was not so much that he was curious about Sun Tianqi's clues, but that he wanted to use Sun Tianqi's clues to see if he was really looking for a way to rescue Ban Wan.

"Then, what is the origin of the Ghost Fang Sect?"

Regarding this, Yue Guanchao really didn't know, he could only guess in general terms that the Ghost Fang Sect was a member of the Ghost Fang clan whose bloodlines were confused, and he wanted to enter Shennongjia to find the soul bone.

Sun Tianqi became cautious and continued to explain: "The Ghost Fang Clan, where the Ghost Fang Sect is located, was one of the nine surnamed Ghost Marquis canonized by the Yin Shang Dynasty back then, and its status was almost the same as that of the Xibo Marquis and the Ehou Dynasty, but with the decline of the Shang Dynasty, they could not help but lose their status, and even most of them were hunted down and killed by the Shang Dynasty and had fled to the northwest. ”

"When the Zhou Dynasty destroyed the Shang, the Nine Marquis once sent troops to help the Zhou people fight the Yin Shang, and later, the Nine Marquis was given different surnames to establish the Fang State, and in the northwest land intermarried with the local clans, and became the princes of the Zhou Dynasty, these Hou Bo Fang States are countless, probably distributed in today's Shaanxi Bashu"

"If you want to say which branch he came from, I really can't tell you, after all, even his ancestors have turned to ashes, and it is too difficult to find the source of this branch, but when I investigated him, I found out that the surname of the ghost Fang was changed back during the Republic of China, and the original surname of the ghost Fang family was Kui before the Republic of China, and the ancient Kui Tonghuai was probably a descendant of a certain ghost Fang in the Jianghan Plain."
