The method is simple, send a team of people directly inside the dark river and float down with it all the way. However, during this process, these people have to hold something in the shape of a copper basin or something similar in their hands.
While they pounded vigorously underneath, the people on the ground would follow them all the way on the ground searching for the sound and posting markers along the way.
In this way, a basic direction of the river can be roughly worked out according to the last mark.
This is the best method!
The Third Elder immediately nodded and said, ”This method is fine, but then, it doesn’t have to be so troublesome. What I mean is that the river is almost as good as if we divide it downwards by a dozen metres or so, and as long as we destroy a large portion of it, then these currents will naturally not be able to flow out.”
Under a distance of a dozen metres or even a bit longer, the mud would stop these underground waters at the source completely.
Or in other words.
Even if it couldn’t be stopped, at this distance, it would still be enough for the water to penetrate for a long time, and basically, it was unlikely to be able to affect the battle below.
“After the people below enter the dark current, they should always remember one thing, the speed as much as possible should be given to slow down a bit, because the people above need to capture the sound, at the same time, as you can see, there is a terrain restriction up there, so it may not be possible to match it at full strength in terms of speed.”
After arranging everything, the Third Elder waved his hand, and his subordinates quickly switched on the action.
The action was quick and efficient, and within a short time, a team of a dozen or so people directly touched inside the underground dark river, while at the same time, the people above were ready to listen to the sounds below.
In order to save time by succeeding at once, the sounds created by the people underneath were actually divided into many kinds.
There were direct and non
There was the direct and very dry knocking sound, there was also the sound of people directly shouting with their mouths, and there was also a special secret code created with the use of mana.
In short, all the sounds were made so that the people above could hear them more easily and clearly.
And the people above were not only those who listened to the sounds, but also those who could make markings at any time, and in addition to the same markings, there were also some people who were responsible for making a corresponding assessment after the lines came out.
This assessment is a comprehensive assessment of the last river based on some lines drawn on the ground.
This assessment can make an approximate location of the river, so that the next step can be directly carried out to blow up the river.
The process is very complicated, however, there are more people, and after dividing up the work, it is actually much simpler.
About half an hour later, all the measurement and construction works had already been carried out.
all completed.
Although the marked places did not give a very complete line, however, on the whole it was indeed not seven but eight.
“Elder, according to the plan, we’ve made about thirty metres or so of extension lines.”
“If we destroy these, then the water source underneath can basically be cut off.”
The subordinate quickly reported back, and the Third Elder smiled gently, very satisfied.
“Very well, at the same time you guys were busy surveying, a brother discovered two other rivers.” The Third Elder said happily.
With more than ten thousand people, it was obviously impossible to just wait here so dryly for the survey, excluding a part of the people waiting at the scene, the others still searched around.
This was intentionally authorised by the Third Elder, because after the Third Elder had measured the approximate width of the first river, he found that although this river was large enough, if it was placed in the branch of the
supporting half a million sailors, it was actually not quite enough.
Although the enemy may not necessarily want to keep all 500,000 troops unaffected, however, anyone with a little bit of brains could think that the other party would certainly do their best to ensure that more people in the 500,000 would not be affected.
Therefore, the possibility that the other side may have other hidden rivers still exists.
It was also based on this, so he told the others to continue searching the surroundings.
This group of people were staying here anyway, and having them do something about it wouldn’t in fact affect anything too much.
As a matter of fact, he was right to do so, because just ten or so minutes ago, those searching subordinates had come to report that they had found the same water source as this place, and together with this place just now, it was a total of three places.
“Now, we’ll soon be able to watch a good show.” The Third Elder smiled contemptuously.
