The black waters, located at the extreme western border of Ningguo, have a vast area and a radius of thousands of miles.

Among them, rainforest swamps can be seen everywhere, and waterways crisscross and crisscross them. The terrain is too complex to outline.

The reason why it is called "black water" is naturally because this area is pitch black. Here the sky is dark, and the earth is also dark. It can be said that it is a completely dark world.

Above the sky, heavy black clouds obscured the sky and the sun, and they did not disperse for a long time. Occasionally, acid rain as black as ink would fall, corroding everything on the ground.

On the ground, the mud, rocks, grass and trees, rivers and lakes are all pitch black. Especially in the river, dead wood and bones sink and float in it, and the smell is so foul that it smells disgusting.

It stands to reason that in such a harsh environment, there will be no living creatures at all. However, this is not the case.

The rainforest is full of snakes, insects, rats, ants, poisonous snakes and beasts. In the swamp, the poisonous fog is pervasive, and it does not disperse all year round. In the middle of the lake, river spirits and water monsters lurk in it.

Because of this, this black water area is full of dangers and dangers, and no one wants to approach it at all.

Of course, this is only for the average person. If you are an immortal cultivator, it will be very different.

Because, for immortal cultivators, the more sinister, weird, and unusual the place, the more likely it is to hide some treasures. Therefore, many monks came to go deep into it and find out.

It's just that these monks, without exception, all fell into it. Even if one or two were lucky enough to escape, they were still dying, and it didn't take long for them to die.

According to the monks who escaped, there were no treasures in these waters at all, and there were only countless dangers. Opinions differ as to what the danger is.

Some say that there are ghosts and ghosts in it, wandering in the forest; some say that they have seen the walking corpse of bone demons, rampaging through the mountains and forests; some say that they have seen a giant python with a body like a mountain; some say that they have seen hundreds of water ghosts, stirring up the rivers; and some people say that there are ghost kings in the Jindan period who are 100 feet tall and have green faces and fangs......

Of course, these claims are not all untrue, and most of them are false rumors and exaggerations, which are not enough to be believed. However, from these rumors, it is enough to see that people are afraid of this place, and the danger of the black waters!

So, are there any treasures here? Of course not. The reason for this certainty is naturally because someone has already thoroughly explored this place. And this person is none other than the third generation of the Son of Heaven of Ningguo.

It turned out that the third generation of the Son of Heaven of Ning Kingdom heard that there was such a strange and mysterious area in Ning Kingdom, and he was very curious, so he led nearly 100 Black Tiger Guard elites to explore the black waters. It's just that this exploration has turned over the black waters, but there is no gain. This Emperor of Ning Guo was completely dead, and directly classified this place as a forbidden place, and then ignored it anymore.

And this expedition not only did not gain anything, but instead lost the soldiers and lost the lives of many Black Tiger Guards in vain. If this matter is publicized, I am afraid that it will become the laughing stock of the people, and it will not be easy to explain to the families of these Black Tiger Guards. Therefore, the royal family of Ningguo blocked the news, only claiming that these soldiers were on a confidential mission, and unfortunately they were killed, so the matter was hastily closed.

Of course, this matter was only hidden for a while. Later, somehow, it was leaked out, and it spread, and even caused a sensation. For a while, in the streets and alleys, there were non-stop discussions, and after tea and dinner, they were introduced as talking points, which made the royal family of Dening lose face.

Because of this, the people of Ning Kingdom know that the black waters are dangerous and abnormal, but there are no treasures. Since then, no one has ventured into the area. After a long time, the black waters were gradually forgotten by the people of Ningguo.

This time, if Guang Yuanzi hadn't discovered that this was the site of Heimanglou, that is, where the Kingdom of Siam was located, I am afraid that this black water would not be remembered by the world, and no one would have gone deep into it.

Shen Yun spread the map of the black waters on the ground, thinking of this information about the black waters, and he was distracted for a while. When he came to his senses, he brought the map closer and examined it carefully. I didn't put it down until I had all the terrain engraved in my mind.

After all, the black waters themselves are a treacherous place, full of murderous opportunities. Now, there are even Heimanglou people lurking in it, and the danger has increased several times. How could I not be careless and treat it seriously?

Having said that, this is where the ruins of Heimanglou are located, and it is the nest of the Heimanglou people. The other party is lurking here, and he must be familiar with this place, and he will take advantage of the time and place. Even though there are a large number of people and others, and all of them are good at cultivation, they are even stronger in the later stage of the liquid transformation period. But is it really possible to conquer this place so easily and win?

Thinking of this, Shen Yun frowned slightly, secretly worried. It's just that if it comes, it will be safe. It's useless to worry about it.

As soon as he thought of this, Shen Yun exhaled lightly and stopped thinking about it. Next, he sat cross-legged, put his hands flat on his knees, got rid of distracting thoughts, condensed his mind, and quietly practiced the "Turtle Breath Technique" mental method.

The "Petrified Tortoiseshell Gong" is a secret method for refining the body, and it is naturally difficult to cultivate. And the "Turtle Breath Technique" is just an air-holding method attached to it, and it is very easy to cultivate. There are two main points in this method.

The first point is to hold your breath, that is, to enter the state of turtle breath. To do this, start with breathing. That is, to adjust the breathing and control the heartbeat. Let your breathing and heartbeat gradually slow down, and finally make your breath like a gossamer, and your heartbeat will not notice. When you learn the method of breathing and breathing, you can try to hold your breath, that is, turtle breath. True breathlessness means that breathing stops, the heart does not beat, and enters a state of suspended animation, like a dead person.

The second point is petrification. The petrification here does not refer to the tempering of the flesh and the petrification of the muscles, but the petrification of the surface of the skin. In this way, a petrified "film" will be formed, which will wrap the whole body, not only will the breath not be exposed at all, but also let itself exude the smell of mountain stones, like a big stone.

Thinking of this, Shen Yun exhaled lightly, calmed down his mind, and then thought about other things.

Speaking of which, after Uncle Guang came back, he arranged for himself, Wei Tianci, and a group of monks to board the warship and head for the black waters.

As for how many troops Heimanglou has, is there any danger in the black waters, and what tactics should be used to attack? I didn't tell myself and the others, and I don't know how this Uncle Guang thought about it.

However, this Uncle Guang is thoughtful and has amazing means, so he will make arrangements, so why do he need to worry about it?

As soon as he thought of this, Shen Yun didn't think much about it anymore, the light flashed in his hand, and a map appeared, which was the topographic map of the Black Waters.
