"The place is so big, where should we blow up? This... we can't blow up everything, right?"

If they are all blown up, it means that the entire top of the mountain needs to be blown up. This huge amount of work is obviously not something that the group of people in front of them can do.

"As stupid as a pig." The third elder was speechless: "If you explode like this, you may not be able to blast many rivers until tomorrow morning."

As soon as he finished speaking, the third elder glanced around.

This is really not easy to explode. Although the river course has been determined, it is difficult to estimate the specific location of the river because it is an underground river.

If you let people float down the river, you can indeed find its location, but how to transfer it to the ground correctly is also a difficult task.

"Back to the elder, I have a method that will allow us to determine the direction and location of the river as quickly as possible."

Hearing this, the third elder turned around and asked: "What can I do?"

The subordinate hurriedly came to the ear of the third elder and explained the method, and the third elder suddenly beamed with joy.

This method is very simple. Send a team of people directly into the underground river and float down with the river. However, during this process, these people have to hold something in the shape of a copper basin or something similar.

They were banging hard underneath, while the people on the ground were following the sound and posting signs along the way.

In this way, a basic direction of the river can be roughly calculated based on the final mark.

This is the best way!

The third elder immediately nodded and said: "This method is okay, but it doesn't have to be so troublesome. What I mean is that we can divide the river down more than ten meters. As long as a large part of it is destroyed, then these The water will naturally not flow out."

At a distance of more than ten meters or even longer, the soil will completely block the groundwater from the source.

Or in other words, even if it cannot be stopped by then, judging from this distance, it is enough for the water to penetrate for a long time, and it is basically unlikely to affect the battle below.

"After people below enter the undercurrent, they must remember one thing. The speed must be slowed down as much as possible, because the people above need to capture the sound. At the same time, you have also seen that there are terrain restrictions above, so the speed must be It may not be possible to fully match it.�

After everything was arranged, the third elder waved his hand, and his subordinates quickly started taking action.

The action was very fast and efficient. In a short time, a team of more than a dozen people directly entered the underground river. At the same time, the people above were also ready to listen to the sounds below.

In order to achieve success in one go and save time, the people below actually created many types of sounds.

There are direct and very crisp knocking sounds, there are also sounds of people yelling directly with their mouths, and there are also special unique codes created by using magic energy.

In short, all the sounds are designed to make it easier and clearer for people above to hear.

The people above are not only those who listen to the sound, but also those who can make marks at any time. In addition to the marks, there are also some people who are responsible for making a corresponding assessment after the line comes out.

This assessment is a comprehensive assessment of a river based on some lines drawn on the ground. JrNovels.com
