The attached tribes are very complex and are mainly distributed in Huaiyuan, Anyuan, Anbian and Dongping Prefecture in the north.

More than a hundred years ago, Bohai established the country, and then decided on the strategy of advancing southward.

The Battle of Madushan went smoothly at the beginning. The Turks and Khitans combined forces to defeat the Tang Pinglu Army and the Heishui Mohe and Shiwei Allied Forces. The Tang Dynasty lost more than 5,000 people. Later, they attacked Silla and captured the Qingchuan River Basin, and fought with the Tang Dynasty.

Silla is bounded by the Daedong River.

But after all, the Tang Dynasty had a strong national power. This strategy had huge limitations, and there were also different opinions in the country——

In the fourteenth year of Kaiyuan (726), the King of Bohai sent his brother Damen Yi and uncle Renya to send troops to attack Heishui Mohe.

Damen Yi had been a hostage in the Tang Dynasty and did not agree to attack Heishui Mohe, a vassal of the Tang Dynasty, thinking that it might attract the Tang army to rescue him.

"The soldiers of Menyi arrived at the border and wrote a letter to solidify their admonishment. Wuyi was angry and sent his brother Da Yi, Xia Dynasty Menyi, to lead the troops to conquer Menyi and wanted to kill him."

As a result, a civil war broke out, and Damen Yi was defeated. He traveled to the Tang Dynasty and was awarded the title of General Zuo Xiaowei.

After the death of Da Wuyi, Da Qinmao succeeded to the throne. During his more than 50 years in office, he actively crossed the Great Wall of the North (the border wall to defend Heishui Mohe) and opened up to the north, cutting off the road to the Tang Dynasty from the five tribes of Heishui.

Nowadays, the foundations of all the prefectures in the north were basically laid during the reign of the Bohai King, posthumously named "King Wen".

After Da Qinmao, he continued to move northward and moved his capital north to Longquan Mansion in Shangjing.

During the Zhenyuan period of the Tang Dynasty, the Yuexi and Yulou tribes of Heishui Mohe came to Chang'an to pay tribute for the last time, and there has been no news since then.

During the Great Yi earthquake (830-858), the territory of the Bohai Kingdom reached its peak, with five capitals, fifteen prefectures, and a total of sixty-two states, making it a prosperous country in the east of the sea.

The current internal tribes of Bohai Kingdom are the tribes that surrendered after conquering the northern prefectures.

As for the Five Blackwater Tribes, they were the Jizu Tribe who fled northward after being defeated, and then "feared their subordinates".

The Jisu tribe has not been very obedient since more than 20 years ago. They actually betrayed their patriarch and made peace with the Silla Kingdom. This shows the rapid decline of the Bohae Kingdom.

Li Shouxin deeply suspected that the Bohai Kingdom was able to recruit 5,000 Blackwater Mohe soldiers this time, but they were actually hired with money.

But it didn’t matter, as long as the Khitan could be defeated, it didn’t matter how he came, so he asked: “When will we send out the troops?”

"Why are you so anxious, Mr. Li?" Pei Zhuan said helplessly: "It's only April now, the grass has just turned green and hasn't grown tall yet. How can we send out troops? Furthermore, all the soldiers and horses must first practice together and become familiar with each other. In short,

It has to be mid-May."

"Bohai is dominated by infantry troops, so why wait for pasture to grow?" Li Shouxin asked.

The Bohai State developed both agriculture and animal husbandry, but mainly focused on rice cultivation and supplemented by animal husbandry. Their military system was mainly based on infantry and less cavalry.

The Blackwater Mohe and Fan soldiers also mainly engaged in fishing and hunting, supplemented by herding. In fact, they were also infantry, but they could only ride horses. They were not the same as the Khitans.

Since the main force is infantry, why wait for the pasture to grow?

"The country has suffered from wars for many years, and there were floods last year. There were many bad harvests, and there was not enough food in stock. What can I do, what can I do," Pei Zhuo said.

Li Shouxin stared at him.

Pei Zhuan had no expression on his face and only said: "The court has decided to send troops to attack the Miaojie Mansion in mid-May."

The direction of this attack is also very subtle. The Miaojie Mansion was occupied by the Khitan, and the Bohai army killed them in order to regain the lost territory. As for whether they will continue to advance westward and invade the Khitan territory after regaining the lost territory, it is difficult to say.

Li Shouxin suddenly smiled and said: "Let it be May. By then the king's army has arrived and can encircle Khitan."

At this point, he was able to deliver. After all, he persuaded the Bohai Kingdom to send troops. However, it was still a bit regretful. If Bohai could be sent troops earlier to attract the Khitan's attention, Wang Shi would be more confident.

Unfortunately, the Bohai people are not stupid. They want to wait for Master Wang to fight the Khitan people first, and then take advantage from behind.
