The immortals in everyone's mouths are standing at the gate of the underwater Dragon Palace at this moment.

The shrimp soldiers and crabs guarding the Dragon Palace will be frightened by the momentum revealed by his body and their legs will be a little weak, trembling but not daring to retreat, the weapons in their hands more faithfully reflect the mood of the master, shaking and shaking, and the sound of teeth rattling is mixed with the clanging of the armor, which is embarrassing.

In fact, they were very calm at first, and when the monk in Tsing Yi came to the gate of the Dragon Palace, they also habitually yelled, scolding the monk who did not know the etiquette, and warned him that the Dragon Palace was not a place where cats and dogs could come!

This is not the Dragon Palace of ordinary rivers and lakes, but one of the largest rivers in the world, the Dragon Palace of the Black River!

The Heihe River originated in Shuzhong, turned north into the territory of the Great Zhou, and then turned south through the Han Dynasty, and then entered the sea in the Great Chu State, and the length of the river was unparalleled in the world. Over the years, because of siltation, the river has become wider and wider, and the river basin has become wider and wider—for the dragon clan, this is a symbol of identity and status!

As a subordinate of Heihe Dragon Monarch, these shrimp soldiers and crab generals have always been very confident and arrogant. In their opinion, in addition to Nanhai and Yunmengze, Heihe will be ranked third. And as a naval army in the third water area in the world, he naturally has every reason to be proud of the legendary Divine Water Lake of the Ancestor of Ten Thousand Waters was directly ignored by them, after all, no one has ever seen the ancient dragon god or something, right? Even where Lake Shenshui is is still a mystery!

Over the years, whenever there are monks who ask to see, they are honestly waiting for the dragon monarch to be summoned on the river bank after sending a prayer post, and most of them are not qualified to see the dragon king, and they are generally sent away by a river patrol yaksha, occasionally a few high-status people, or those who have a relationship with the dragon clan, must also be summoned before they can enter the dragon palace under the guidance of the shrimp soldiers and crab generals, not many people take half a step along the way, not many glances one by one, this is the style of the dragon palace, this is the majesty of the dragon clan!

But this monk didn't understand the rules at all, so he went straight into the water, relying on his skillful skills, shook off the river patrol Yaksha who wanted to stop him, and went straight to the gate of the Dragon Palace.

It's the other way around! There are no rules for this!

They were very angry, scolding and trying to do it.

But the next words of the monk in Tsing Yi made the shrimp soldiers and crab generals stay there, and the river patrol Yaksha, who hurriedly came to attack back and forth, shrank his head and slipped away silently.

What he said was: "I am Qingyang Guan Wu Xie and want to talk to Long Jun about the flooding of the Black River. ”

When these words were spoken, all the water tribes were stunned for a moment, and then they came back to their senses, their legs suddenly began to weaken, and their bodies trembled like swings.

Qingyang Guan Wu Xie is not an ordinary monk, he is an outstanding figure who almost single-handedly destroyed all the young masters of the Eight Sects of the Demon Sect in the Battle of the Three Sects!

And not only that, according to the well-informed demon clan predecessors, this guy is likely to be the reincarnation of the famous fire god Taixuzi in the past...... Who is that too empty? It was the super master who destroyed the East China Sea Dragon Clan in the battle between good and evil! And what's even more terrifying is that Taixuzi not only destroyed the East China Sea Dragon Clan, but also killed almost all the water tribes in the East China Sea with one fire! It's a super evil star that is unique in the sky and on the earth!

For thousands of years, the water tribe has always used words such as "if you don't sleep well, the Taixuzi will come to cook you and eat you at night" to scare children, and there is also a gambling curse of "If I talk nonsense, I will meet the Taixuzi when I go out" The gambling curse swears, the power is great, the fierce flame is high, and it is even more terrifying than the sword abandonment who once sat on the edge of the South China Sea, and one person and one sword blocked the South China Sea Dragon Clan for ten years and did not dare to go out!

Wu Xie is the reincarnation of Taixuzi...... It's too empty?!

When they heard Wu Xie report his identity, the first reaction of these two shrimp soldiers and crab generals was "My mother!" Could it be that the words of the previous curse have been fulfilled?"

So even though Wu Xie didn't show the slightest hostility, they were still so scared that their souls didn't possess their bodies, if it weren't for the strict rules of the Dragon Palace, they were afraid that they would have fled into the Dragon Palace screaming a long time ago.

At this time, they are extremely envious of the river patrol Yaksha who usually looks down on the river patrol one by one! It's good to patrol the river! You can just turn around and leave!

If Wu Xie could hear their inner wails, he would probably dub them with a famous anime line from his previous life.

"Coach...... I want to go on a river cruise!"

It's a pity that Wu Xie can't read minds, so the scene that could have been entertaining naturally won't happen. He just stood quietly at the gate of the Dragon Palace, with an easy-going smile on his face, facing the two trembling shrimp soldiers and crab generals.

It was a very strange scene, one side was relaxed and peaceful, and the other side was trembling as if facing a great enemy, as if there were two different worlds.

The people of the Dragon Palace were obviously quite sensitive to the name "Wu Jie", and after a while, hundreds of heavily armed shrimp soldiers, crab generals, mussels, Yasha and other sailors, under the leadership of the two nervous dragons, rushed out, lined up left and right, and then a dragon monarch with a jewel all over his body was enough to flash people's eyes, and he didn't know how many magic weapons he had worn.

"I am the Black Water Dragon Monarch, I don't know what Qingyang Guan Wu Daoyou has to teach here?"

This dragon monarch was simply put on a posture of preparing for a big battle if he didn't agree with a word, and he didn't talk in circles, and went straight to the point when he came up.

Wu Xie smiled and said, "Wu Xie pays a visit to Long Jun." I don't know if Long Jun knows that this black river is getting shallower?"

Long Jun was stunned for a moment, he didn't expect what he said to be about this matter, he thought about it for a while, and nodded in response: "I naturally know about this matter, but the river becomes shallower, which means that the river channel becomes wider and the scope of the Heihe River becomes larger, which is not a bad thing for our water tribes." ”

"It seems so for now, but what if the river becomes shallower?"

"Then the river will be wider, and there's nothing bad about it."

"But what if there's a drought?"

Long Jun smiled: "Traveling clouds and spreading rain is my specialty, if there is a drought, my generation will rain it." ”

Wu Xie didn't say anything, his hand flipped over, and the colorful light gathered and turned into a golden talisman and flew towards Long Jun.

"This is the climate of the next hundred years calculated by the method of heavenly performance, Long Jun might as well take a look and talk about it."

Long Jun took the talisman suspiciously, probed his divine sense into it, his face suddenly cloudy, and his brows tightened.

"Actually, I've also heard of the dragon clan's method of spreading clouds and rain. The water used did not come out of thin air, but was moved from somewhere else. If there is a drought everywhere, I don't know where the Dragon Monarch wants to draw water from?"

“…… If there is really a great drought in the future, our generation must not be prevented! However, the Heihe River is nearly 10,000 miles up and down, and more sediment is rushing down from the upstream day by day. Even if our generation is good at underwater kung fu, it is difficult to dig deep into the river!"

Facing Long Jun's complaints, Wu Xie smiled and said the true intention of his trip.

"Long Jun don't have to be embarrassed, I have a method of 'harnessing water and attacking sand' here, although it can't be applied everywhere, but it can greatly reduce the hard work of your department, if Long Jun is interested, you might as well try it."

As he spoke, he slowly sent the jade slip that recorded the method of "harnessing water and attacking sand" to Long Jun.

The method of harnessing water and attacking sand is a special idea of water conservancy engineering in ancient China. Wu Xie didn't learn this when he was in school, but after he went into society, he accidentally read online novels and learned this trick

The idea is simple, which is to increase the flow rate of the river, and at the same time strengthen the riverbed so that the river water cannot erode the riverbed, and in turn strengthen the scouring of the river bottom to roll up the sediment and reduce siltation.

This is an idea of governing the Yellow River in ancient times, whether it has worked in history or not, Wu Xie is not clear, but the faces in online novels seem to be effective, one by one, one or two Internet writers will talk nonsense, and they can't all be nonsense! And he still reads some popular novels, the level of the authors is relatively high, there is no reason why they are all historical inventors, there must be a few slightly more reliable ones.

Therefore, when he found out that the Xiaohuai River has been flooding often in recent years, it is because the Heihe River has silted up, raised the riverbed, and increased the pressure on the tributaries to discharge floodwater, so he wanted to solve this problem well.

Of course, he is not a person who talks about the river, he has already contacted his brothers and sisters to do experiments - one by one, they temporarily dug a small river, cast a spell to bring a lot of sediment to the river, and then the river naturally and slowly silted, but as long as the embankment is strengthened and the river surface is reduced, the flow rate can indeed be effectively increased, and the siltation situation will be greatly improved!

This experiment strengthened their confidence, which is why he visited the Black River Dragon Monarch with the method of attacking the sand with the water and sand.

If you want to talk about the understanding of water flow, Heihe Longjun is naturally far above Wu Jie. Wu Xie needed to do experiments to determine, he just looked at the information, pondered for a while, and then fully understood, and nodded again and again.

"It works!" Long Jun's face was no longer hostile at this moment, but full of admiration, "The silting up of the riverbed has always been a major matter that our water tribe is worried about. Well, the solution that has been solved in the hands of Wu Daoyou is here, on behalf of the same clan of all rivers in the world, thank you Wu Daoyou for your guidance!"

As he spoke, this Dragon Monarch bowed deeply to Wu Xie and almost fell to the ground.

Wu Xie hurriedly returned the salute One by one, although Heihe Longjun is only refining and cultivating, he is much higher than him in terms of age and prestige, and he is at the same level as his uncles and uncles in terms of seniority, he is not the kind of mana who thinks it is in vain when his mana is high, and wants to raise his seniority out of thin air

And if you want to do a good job in this method of attacking sand with water, it is really necessary for the dragon clan to attack the sand one by one, and it will not reduce the amount of sand, but only introduce the silted sand into the river again, once the river slows down, it will still be silted up after all. The Heihe River is thousands of miles up and down, and it is inevitable that there will be some gentle places for people to cross the river, and those places will be silted up on a large scale at that time, and only the water tribe will have enough manpower to work day in and day out to remove the silted sediment.

Bidding farewell to Heihe Longjun, who was full of interest and ready to arrange the method of harnessing water and attacking sand, Wu Xie left the vast river and stood in the air and looked at the west.

Senior Brother Yi has already gone to the Great Han Kingdom to persuade people not to cut down trees excessively, pay attention to protecting the riverbed, and avoid soil erosion.

The coming drought is unstoppable, but if all kinds of plans work, it will not necessarily reduce the damage to an acceptable level.

In this world where there are really all kinds of strange forces and chaos, Wu Xie didn't dare to say that anyone would win the sky, but he firmly believed that as long as he found a suitable way, in the face of Haohao Tianwei, manpower would always be able to make a difference.

Even the daytime is possible, so why can't we prevent and fight disasters?

At this time, there is a lot to be done!
