At the critical moment of blowing up the lake and releasing water, those who are directly interested in it all raised their hearts to their throats, and the success or failure of digging the ditch was about to be revealed. Even if there is no direct interest, those who are ready to explore the Blackwater Lake, or even just join in the fun, are looking forward to the success or failure of the water release.

The Dangang Realm of the Qingfeng Sword Sect belongs to the forces of the Qingfeng Sword Sect, as long as there is no rebellion, it will definitely hope to succeed in releasing the water. This is not only related to the benefits of draining the Blackwater Lake, but also to the respective fame.

These people who have direct interests, they can only succeed, not fail!

Wu Dabao and others are ready to explore Heishui Lake, hoping that the water release will be successful. They don't get much benefit, they have less desire to succeed, they don't think so strongly, but they want to succeed after all.

And people like Wu Feng may be the only one who is completely curious, simply joining in the fun, and doesn't care about success or failure. But this kind of thought, analyzing the situation is more rational and does not have a subjective tendency.

What's more, Wu Feng is the only person who dives in Heishui Lake, and he estimates the water capacity of the Black Wolf Canal and Black Wolf Valley, so he knows the best result, that is, the water level of Heishui Lake is reduced by 500 zhang, and it is impossible to drain Heishui Lake.

And the black and white magic spears from the Silver Spear Club were also looking forward to the result of releasing water, but they preferred to fail in order to combat the Qingfeng Sword Sect's approach.

"Boom, boom, boom" Everyone had different thoughts, but no one made a sound, only heard the roar of the talisman exploding the earthen wall and the black water.

"Let go of the water!" everyone's mind came up with such thoughts, and the idea of anticipation reached its peak.

The earthen wall was successfully exploded, and the people who were watching dispersed a little, turning to notice the changes in the water of the lake.

The ditch is 500 zhang wide and 800 zhang deep, with a huge amount of drainage, near the gap in the ditch. The water of the Black Water Lake flows out rapidly, and the water level quickly decreases, and the water that used to be a waterfall becomes a gently flowing water surface.

"Huh, the water level of the Blackwater Lake is lower, if nothing else......" Wu Feng noticed the surface of the lake in his sight. A large amount of black water poured down, and the water level dropped a little, so I paid more attention to it.

The rest of the people who watched the explosion of the lake saw that the earthen wall was blown up, and the lake water was successfully released, and all of them scattered to the lake, observing the changes in the water level, and noticed that the water level was lowering, except for the black and white magic guns. The rest were happy.

However, this happy idea did not last long, and the water level of the lake was lowered, mainly near the ditch, and the further away the lake, the water level changed very little.

The strong corrosiveness of black water, the density of black water is larger. It is roughly higher than the density of ordinary clear water, about 50%.

Because the density of water is high. The water level of the lake is sloping and showing a gentle slope, which is even more obvious.

From the mouth of the ditch, the lowest point of the water level is the center, and it expands in a fan shape towards the black water lake, and the water level gradually becomes higher. Extending for more than 100 miles, the water level has not changed in the slightest. Although the ditch is still flowing, a balance has been formed.

Everyone rushed to the edge of the black water lake to observe the changes in the water level, and they had already stood by the lake at the mouth of the ditch. Looking into the distance.

And some people are staying far away, after all, a large amount of manpower digging ditches is all gathered by the Heishui Lake, which is not an exaggeration at all. Those who were weaker in the Earth Yuan Realm and Lingwu Realm had already lined up hundreds of miles away.

The inclination of the water level showed an astonishing spectacle, and it soon became known to everyone, and the people who were originally at the mouth of the ditch hurried to investigate.

After all, it is an unchanging law since ancient times that water flows to a low place, and the water level is uneven, and there is a slope, which is quite unreasonable.

"The current situation, I'm afraid there is an accident!" Wu Feng thought to himself, he was still estimating that if there was no accident, the water level of Heishui Lake would be reduced by at least five hundred zhang. But the current situation, hundreds of miles away from the mouth of the ditch, the water level is stable and unchanged, which is obviously a very unexpected situation.

In fact, Wu Feng knew very well in his heart that it was too early to say this, after all, according to the water flow of the Black Wolf Canal, which is eight hundred zhang deep and five hundred zhang wide, it will also take five or six days to fill the Wild Wolf Valley.

Even in the beginning, a large amount of black water flowed out, and the water level could not be lowered, which was normal. After all, there is the Heishui River, which constantly pours into the Heishui Lake, one in and one out complementary, which can maintain the stability of the water level in a short time.

However, the flow of the Heishui River is not as large as that of the Black Wolf Canal. The Heishui River is on average, just three miles long, roughly five hundred zhang, which is equivalent to the Black Wolf Ditch.

However, the Heishui River is relatively shallow, the deepest is only five zhang, the average depth is three zhang, and the flow rate of the Heishui River is only one percent of the Black Wolf Canal. It's not even this flow, after all, the specific drop between the Heishui River and the Black Wolf Canal is different, and the flow rate of the Heishui is different.

In this way, in fact, the current water level can predict the outcome. If the change in the water level does not spread out, it will only remain stable, and the failure of the project of digging a canal to release water is basically no longer in suspense......

Qingyun Sword and Black and White Magic Spear, three old monsters of Dangang Realm, patrolled the lake in the air, and detected the changes in the lake, the Black and White Magic Spear was extremely excited, and the White Devil Gun said: "Alas, Qingyun Sword Daoist friends this time, I'm afraid I'm going to be busy in vain!"

"If you are busy in vain, you will be busy in vain, the Qingfeng Sword Sect has a great cause, and the Qingyun Sword Dangang Realm master has a very high status in the Qingfeng Sect, so I don't worry about this loss. "The Black Magic Spear cooperated with the opening, and at the same time squeezed the Qingyun Sword, such a good opportunity to strike, they naturally wouldn't miss it.

Moreover, such a blow is not only the fighting spirit between the three Dangang old monsters, but also the words. The words of the black and white magic spear, with their cultivation in the Dangang realm, were clearly transmitted to the lake, not to mention that all people heard it, at least most people heard it.

What's more, between the words, it was not only aimed at the Qingyun Sword, but also implicated the Qingfeng Sword Sect.

"Hmph! The Wild Wolf Valley is huge, and now the lake has just been blown up and released into the water, and the water is still in the Black Wolf Canal, and it has not yet flowed into the Black Wolf Valley. The Heishui River keeps flowing into the lake, and it's normal for the water level to be stable, don't be too happy!" Qingyun Jian snorted coldly, his words were just as clear as they reached the ears of everyone by the lake.

And Qingyun Jian never admitted defeat, and attributed the situation of the water level to the short time and the factor of the infusion of the Heishui River, which can be recognized by some people.

But in Qingyun Jian's heart, he was already extremely anxious, he knew very well what the situation would mean when the water level stabilized at this time.

The flow of the Black Wolf Canal is large, and the huge drop makes the black water flow out of the gap quickly like a flood.

But this kind of flow only makes the water level of Heishui Lake, in the area of a hundred miles fan, show a change in slope. And hundreds of miles away, the water level remains stable, and such a steady dìng indicates that the water flow is balanced.

As long as you are clear about the situation of Heishui Lake, and you are clear about the comparison between the water level of Heishui River and Black Wolf Canal, one in and one out, you can understand Qingyun Sword's statement, and it is not credible at all.

"Qingyun Sword, it's not that we're happy too early, but the result has been decided, why are you struggling?" said the black magic spear lightly, now that the victory was in hand, he didn't say anything more. After all, what they want to fight is not Qingyun Sword alone, but the Qingfeng Sword Sect.

"Alas, the Black Devil, now Qingyun Sword Daoist Fellow, it's still difficult to accept this result, let's wait a few more days!" the White Devil Spear spoke, cooperating with the Black Devil Spear to strike at the Qingyun Sword.

They are not very convincing when they announce the results now, but in a few days, the results of digging ditches and releasing water will be fully visible to the world. Qingyun Sword this time, the situation of failure will be spread quickly, relying on others to spread the news, compared to the black and white magic gun, it can be more believable.

At that time, the Black and White Demon Spear and the Silver Spear would be able to add fuel to the flames from the shadows, and they would be able to achieve the effect of striking at the Qingfeng Sword Sect.

Of course, the Qingfeng Sword Sect will send out an announcement, saying that this project of digging a ditch and releasing water is a decision made by Qingyun Sword alone, and has nothing to do with the Qingfeng Sword Sect.

However, the specific impact depends on the situation, and it is uncertain at this time.

At this time, the clearest result is to remove the three old monsters of the Dangang Realm, not those old monsters of the Mixed Yuan Realm, but Wu Feng hidden in the world.

Wu Feng knew the result, and there was no surprise at all, he rushed from the lake to a hundred miles away to investigate the situation of the water level being stable.

It is 100 miles away from the gap in the ditch, forming an arc, and between this arc and the gap, the water level is lowered from the normal water level to the gap, which is the lowest water level.

Outside of this arc, the water level remains completely unchanged and remains at the original level.

If this arc is still moving outward, it means that the time is short and the effect of water discharge cannot be shown.

If this arc narrows to the gap in the ditch, it means that the water outside is full, and there is no need for black water to flow out, and the surface of the lake with a diameter of 100 zhang will return to the original water level.

Now this situation has not yet appeared, but when the Wolf Valley is full, this will happen.

If the water level arc is stable and has remained the same, it means that the black water lake, the flow of black water in and out, has now reached a balance.

But the flow of the Heishui River, and the flow of the Black Wolf Canal, are obviously different, and there is a huge perception. It is not the rainy season, and there is no remaining fresh water flowing into the lake, so the factor of external water is excluded.

"Heishui Lake is a Heishui River, an inherently flowing lake infused by Heishui, and the water level of Heishui Lake remains unchanged in both dry and rainy seasons...... Wu Feng recalled the situation in Heishui Lake.

"According to normal rivers and lakes, in the dry season, there is water from the river, there is natural water vapor transpiration, and the water level remains balanced, which is relatively normal. ”

"In the rainy season, due to the external rain, the flow of the Heishui River becomes larger, and the other three sides of the Heishui Lake and the mountain range flow out of the mountain torrents, and the water vapor evaporates less on rainy days, and the water level should rise. But it is very unusual to keep it steady. ”

"Now that the ditch is digging and releasing water, the amount of black water flowing out is huge, and the water level of Heishui Lake is still stable and unchanged, what is the reason?" Wu Feng was extremely curious in his heart.

"If you don't have that bone dragon, go into the lake by yourself and explore it again, and you may find some clues. But the bone dragon is hiding at the bottom of the lake, and his current strength, as long as it attracts the attention of the bone dragon, it will be a certain death. Driven by curiosity, Wu Feng was interested in exploring the lake.

But his rational thinking made him quickly dispel his thoughts, the bone dragon was in the black water lake, even if he was not afraid of the black water and wanted to enter the black water lake, he would also kill himself...... (To be continued......)
