Who wants to live in broad daylight like a rat in the damp underground?

So when the rescue team of the Western Cloud Empire appeared in various refugee gathering places in the "Tongyoudi River".

These are either washed deep underground, lost in a labyrinthine network of underground water, or fearful of outside danger.

Except for the panic when he saw the floating ship like a steel monster.

Soon, under the explanation of some rescue guides who were also South Vietnamese refugees, they wept with joy and stepped into the rescue ship with joy and returned to the clear sky.

Only a few refugee leaders who are familiar with the environment of the "Tongyoudi River" are left behind as guides to guide the rescue ship to other refugee gathering places.

It's not that they need to lead the way, since the rescue ship has arrived in the depths of the "Tongyoudi River", it means that the Tianyan Network has detected a thorough here, and the path, hydrology, hidden dangers and whatnot, I am afraid that it is clearer than these refugees.

The main reason for bringing them is to save their tongues, and it is easier to trust the refugees than strangers who know them to explain on their behalf.

Bai Yuqi, who was acting with the ship, did not interfere with the rescue team's rescue operation.

Rescue ships limited by the space of underground water veins can enter the water network of the "Tongyoudi River".

They are all the smallest models of "Mong-class" carrier-based aircraft in the floating fleet of the Western Cloud Empire, and the internal space can carry limited personnel.

It was unrealistic to rely on these miniature ships to relocate all the South Vietnamese refugees who had taken refuge in the "Tongyoudi River", so they could only urgently allocate a batch of portable teleportation arrays to carry them with the ships to teleport the refugees back to the Dayu City refugee camp.

To say that the environment in this "secluded river" is also magical.

Even if there are small caves along the way, the number of refugees that can accommodate is limited, ranging from a few dozen to hundreds or thousands.

What is amazing is that those large caves, the smaller ones are like towns, the larger ones are large enough to accommodate the next large metropolis, and some even stretch for hundreds of kilometers in the mountains, one cave after another, and there are holes leading to all parts of the mountain, and I don't know how many layers there are up and down.

Although there were heavy casualties in the complex and dangerous environment of the "Tongyoudi River", after the continuous efforts of the refugees, they finally found some safe routes, and killed a large number of dangerous water beasts to settle down here.

Exactly how many people went underground is unknown until a full count is made.

According to refugees who have only recently entered the river, the "Tong Youdi River" under the Lei Ze has become the only refuge for the survivors of the entire South Vietnamese raft.

As long as the refugees who are able to rush to the territory of Da Viet country, they do not hesitate to take risks and try downstream, it is better than staying outside and waiting for death.

And because the trees near Razor have been cut down in recent years, there are not enough logs to tie into wooden rows, and many refugees can even jump into the dark river with a single log, fighting for a chance to survive.

Therefore, it is conservatively estimated that in addition to the refugees who fled to other directions, there are billions of people who have entered the "Tongyoudi River", and the remaining ones are more than 3 billion.

Of course, affected by the lack of resources and limited living space, chaos among refugees is inevitable, but after more than ten years of development, a relatively stable ecological system has gradually formed.

The fact that so many people were able to survive in the "Tongyoudi River" was also thanks to the people of Lei Ze Dayue who were the first to enter the "Tongyoudi River".

Razor, as you hear the name, knows that it is a land of water.

There are not many solid surfaces in Da Viet Country, and most of them are scattered scattered in the vast swamps of Ze Island and floating grassland.

Therefore, most of the people of Dayue live in the water, live by fishing, grazing waterfowl and fishing for edible aquatic grass, and domesticate water beasts to drag the rowhouses to migrate in the thunder, belonging to an alternative nomadic people.

It is precisely because of this characteristic of the Dayue people that they are naturally adapted to survive in the "Tongyou River".

When the first batch of Da Yue people entered an underground lake in the "Tongyoudi River".

So he found a way to use the domesticated waterfowl "Serval" to fish, and flew back to Lei Ze to inform other Dayue people.

After cutting and dividing the Luhu Island and the grassland where they originally lived, they were released along the inlet of the underground water vein.

Because Luhu Island is a meadow composed of an aquatic plant with leaves like wheat, stems like bamboo shoots, and gourd-like bulbs, the dense root system is intertwined.

At its thickest, it can reach several zhang, so a large number of gourd-like aerial roots provide huge buoyancy, so that the reeds that are tangled together and float on the water look like floating islands, on which people and animals can walk and even build houses.

In addition, the young leaves, stems and bulbs of the reed can be eaten as vegetables, and can be used as fuel after wilting, so it can be regarded as a plant that is a treasure all over the body.

And "bamboo celery" is a kind of aquatic grass that grows at an amazing rate.

Its stems are like bamboo, the color is like ice, its roots are drawn from bamboo shoots, young leaves and young bamboo shoots can be eaten as green vegetables, and they are propagated by root bamboo shoots.

Roots draw roots, roots and roots, can grow dozens of zhang overnight, cut inexhaustibly, often a little years of "bamboo celery", one can grow into a vast grassland floating on the water surface.

With these two miraculous plants, the people of Dayue who live in the thunder are living leisurely even if the dry and solid land is scarce.

In the face of the invasion of extraterritorial heavenly demons, these two magical plants have become the "life-saving straws" of the people of Dayue.

It was cut into pieces and floated down the underground water veins, and then collected and put together by the Da Yue people who stayed in the underground lake.

Within a few days, it grew into a complete Luhu Island and a patch of grassland with bamboo and celery, laying the foundation for the subsequent refugees entering the underground water veins and providing a place to settle.

And the people of Dayue are also the only tribe that does not need to look for cave life along the underground water veins.

After all, a cave with enough space may not be suitable for habitation, not to mention damp and rugged, and there may be all kinds of poisonous insects and monsters hidden.

And in the underground lake, although there may also be ferocious water beasts.

However, most of the ferocious water beasts are not vegetarians, so they are usually not interested in Luhu Island and the Bamboo Celery Grassland.

Second, even if it is attacked by a giant water beast, the thick and tough reed layer and meadow can resist the impact of the water beast, and even if the other party can bite again, it can still gnaw the entire floating island?
