Meng Zhang didn't go out with Yu Boli's army. He spent most of his time in the ancestral land of the mermaid family.

Yupoli has a long-distance communication device. In case of difficulties, as long as she asks Meng Zhang for help, Meng Zhang can immediately use space transmission to catch up and help her solve the problem.

Of course, if it is not really forced, Yu Polly will not rashly contact Meng Zhang.

After yuboli completely surrendered, the ancestral land of the mermaid family was completely open to Meng Zhang and let him take whatever he wanted.

In the mermaid family's treasure house, there are many rare treasures, especially those special spirits only produced in water, which are particularly precious.

Meng Zhang's main attention was not on these treasures, but on the various classics collected by the mermaid family.

Jiuquhe nationality has its own unique civilization, and Mermaid nationality is a race with wisdom and long inheritance history.

In addition to the classics related to cultivation and recording many cultivation experiences, Meng Zhang is most interested in the records of mermaid history.

Among them, the classics that only the mermaid kings of previous dynasties are qualified to read are the focus of Meng Zhang's attention.

By reading these classics, Meng Zhang understood the origin of the mermaid clan, the origin of the Jiuquhe clan, and guessed the root cause of the internal strife of the Shui clan.

Before the immortal came to preach in the Jun dust world, the Jun dust world was ruled by many native races.

There are gods, sea people and even the real dragon.

Among them, the divine race rules the vast land, and the sea race rules the boundless sea.

Rivers and lakes on the continent are ruled by aquariums.

Some aquariums submit to the divine race, and some aquariums are attached to the sea race

Jiuqu River connects the West Sea, and the aquarium here is closer to the Haizu.

In order to strengthen their control over the Jiuqu River, the Hai people specially sent the mermaid family to rule the Jiuqu River with the mermaid family.

Later, the immortal came to the Junchen world, swept up the local aborigines, and moved a large number of people.

The Terran thrives in the Junchen world and has cultivated countless Terran practitioners.

In the process of becoming the ruler of the Jun dust world, countless wars naturally broke out between the Terran cultivators and the original races of the Jun dust world.

The final result is to form the current situation of Jun dust world.

Ethnic groups such as divine descent were almost extinct, and only a few escaped from the net disappeared and disappeared completely.

The sea clan retreated to the depths of the sea and relied on the shelter of the real dragon clan.

When the situation in the Junchen world changed greatly, the mermaid family was very wise. After judging the situation, they secretly hooked up with the Terran cultivators.

Taking advantage of the defeat of the sea clan, the mermaid clan destroyed the mermaid clan and became the only leader of the Jiuqu River clan.

There are naturally many opposition voices within the Jiuquhe clan.

But at that time, the sea people were gone, the fish people were also destroyed, and the voice of opposition naturally disappeared slowly.

The head of the aquarium was canonized by the sea family and given the throne.

The Hai nationality also helped the Shui nationality establish a royal court.

In the process of destroying the fishman family, the royal court was also destroyed.

On the basis of the ruins of the aquarium royal court, the mermaid family made great efforts to establish a fortress to the sea.

Tonghai fortress has isolated many links between Jiuqu River and the West Sea. It is used by Jiuqu River to defend the sea tribe. However, it does not matter and will not affect Meng Zhang's next action.

Even in the heyday of the Yuren clan, Meng Zhang will not be afraid, not to mention the current Yuren clan.

He just needs to sweep the past all the way. The things behind the Mermaid will be opened by him sooner or later.

After more than two months of rest and reorganization, the aquarium army under yupoli finally looks like a strong army.

Yuboli also wants to quell the civil strife of the aquarium and consolidate the rule of the mermaid family as soon as possible.

Yu Boli personally led this large-scale aquarium army and directly embarked on the journey.

The goal of this expedition is the most likely hiding place of the Yuren tribe - Tonghai fortress.

Those aquarium groups who fled their original territory and avoided the yuboli army have long fled around the sea fortress.

During this period, these aquarium groups not only temporarily settled around the Tonghai fortress, but also strengthened the defense of the fortress.

As the army led by Yu Boli began to approach, the Yuren clan hiding behind finally appeared.

A group of mermaid strongmen appeared in the sea fortress and gained the command of the fortress.

Those rebel mermaids, who are unwilling to accept the rule of yuboli, are quite powerful.

Under the organization of this group of mermaid strongmen, a strong army was soon pulled up.

King Jingou and others were originally the generals of Jiuquhe clan. They already have strong power.

King golden hook is highly valued by the strong of the mermaid. He also runs actively and constantly strengthens the strength of his own army.

The aquarium army led by yupoli went upstream and ran upstream along the main stream of Jiuqu River.

Soon after, the aquarium army led by yupoli appeared not far from the sea fortress.

While Yu Boli led the aquarium army to set out, Jin Qiaoer led an army of friars, took a flying boat and slowly approached the sea fortress from the direction of the shore.

The river surface of the main stream of Jiuqu River is often very wide. Even the narrowest places are at least tens of miles wide.

The most spacious places, hundreds of miles or even thousands of miles, are very common.

The sea fortress is located on a river about 200 miles wide.

In those years, the aquarium King's court was more often called the fishman King's court.

Because the mermaid clan has been the leader of Jiuquhe clan for a longer time than the mermaid clan.

Yuren Wangting is located at the bottom of Jiuqu River. It is a complete underwater city.

In addition to the underwater part, the sea fortress built on the ruins of Yuren Wangting also has dozens of miles of buildings on the water surface.

The fortress was originally an important defensive place for the mermaid family, which was specially used to resist threats from the sea.

But now, it has become a base for traitors to make trouble.

I don't know how the Mermaids captured this fortress at the beginning?

Although who is far from being bloodless, he does little damage to the fortress.

After a little cleaning, the fortress not only restored its original defense, but also became more lethal.
