One hundred thousand miners took Qiu Feng nearly ten hours to rescue them all and entered the temporary camp to rest.

After all the miners were rescued, the rescue team of a thousand people from the dwarves and goblins entered the mine, began to inspect the various mine tunnels, and carried out reinforcement operations.

Qiu Feng originally wanted to leave, but was explaining to Qiu Weiqiang about the arrangements and care of these 100,000 miners, when the system prompt rang again.

System prompt: One hundred thousand urgent! In the mine of Qiyaoxing (9189871, 18114,9107), due to continuous heavy rain, a barrier lake was formed. One hundred thousand miners were trapped in an unusually narrow place in the middle of the barrier lake.

On the safety island, there is now no food and the temperature continues to be low. The situation is very critical. One hundred thousand miners are in urgent need of rescue. Friendly reminder: Whoever saves these miners will gain their allegiance.

Just when Qiu Feng was about to open the panel of the cross-time and space transmission skills, Qiu Weiqiang suddenly took Qiu Feng's arm, pointed to a mountain peak in the distance and said: "Commander, it's not that far away. It should be right after you climb over that mountain peak."

Qiu Feng took a look and said: "Send an armed helicopter over immediately and notify Bawang Town to send an engineering unit over with gunpowder."

"Commander, what are you doing?" Qiu Weiqiang asked doubtfully.

Qiu Feng said: "This is a mountainous area. There is no waterway connecting our current waters. The surroundings are bare. Where can we find wood to build rafts to save these miners? We can only find a thinner mountain wall and blast it.

The trapped miners were rescued by draining the water from the barrier lake.

You still need to continue arranging for the sergeants to send food and edible fresh water, and start arranging to build temporary camps. There are another 100,000 people. This time, we will try to rescue them all in half a day.

By the way, let's notify Bawang Town to drop by some livable renovation engineers to calculate how the water in the barrier lake will flow after the breach is blown to avoid flooding our temporary camp."

Qiu Weiqiang said excitedly: "Yes, Commander, please rest assured that it is done properly and there will be no problems."

Qiu Feng did not wait for Qiu Weiqiang to transfer the helicopter, after all, it would still have to wait until some time later, so Qiu Feng climbed the mountain peak on foot.

Standing on the mountain peak, all you can see is a expanse of white water. In the middle of the expanse of white water, there is a dark island. Although you can't see it clearly, but from the look in the eyes, it must be a human being.

With one hundred thousand miners crowded on such an island, the situation is indeed very critical.

But the scope of the water area is indeed very large. From the peak where Qiu Feng is located to the edge of the island in the center of the water area, it is at least four or five kilometers away.

When Qiu Wei stressed that the armed helicopter was sent over, Qiu Feng had already hiked through half of the mountain peak, and was also looking for weak spots in the mountain wall that could be used for blasting.

After Qiu Weiqiang picked up Qiu Feng, the armed helicopter began to circle around the peaks on the edge of the barrier lake. It flew three times in a row. Qiu Feng said to the three representatives of the engineering Corps on the armed helicopter: "You have found the right one."

Is there a blast hole?

I think the gunpowder may have to be buried at the foot of the mountain, otherwise the water in the barrier lake will not be drained cleanly, which will also be a troublesome matter."

An engineer said: "Commander, this is not a big problem, but this barrier lake is quite special. The mountain wall at the bottom is generally thicker, and the most rippled part is two hundred meters thick. Simply using gunpowder may not be very effective."

Qiu Feng frowned and said: "Indeed, with our gunpowder level, it is impossible to explode a two-hundred-meter-thick mountain."

The engineer soldier said: "Commander, at least it has been discovered that the thickness of the mountain bottom in four places is only 300 meters, but livable reconstruction engineers still need to determine which place to blast so that it will not affect our mines and temporary camps.

Do you think you can ask dwarf or goblin engineers to help our engineers dig a tunnel in the direction of the barrier lake at the selected blasting place? When we are still within ten meters of the edge of the barrier lake, we will

Engineers will go in and place explosives, so our probability of successful blasting will increase many times."

Qiu Feng said: "It's inappropriate. After our engineers ignite the explosives, it will be more difficult to safely evacuate the tunnel, and the risk factor is relatively high. Moreover, after the tunnel collapses due to the explosion, it is easy to form a secondary dam."

The Engineer Corps said: "Commander, although the Engineer Corps has not yet developed the technology for remote detonation, the 150-meter-long fuse technology is still available, and our current directional blasting generally involves drilling a cylindrical hole and filling it with gunpowder.

The maximum force of blasting is penetrating. Theoretically, the probability of blasting directly through the mountain wall is much greater than collapsing the entire tunnel.

Apart from this plan, I have not considered any better plan for the time being."

Qiu Feng looked back at the livable renovation engineers on the armed helicopter. One of the senior livable renovation engineers said to Qiu Feng: "Master Star Lord, in fact, except for the one closest to the temporary camp of the coal mine miners, the other three

It can be done anywhere, but I think it would be better to start work in three places at the same time.

Because the diameter of the tunnels dug by the goblins or dwarves is bound to be limited, even if the penetration blasting is successful, dredging the barrier lake will bring huge pressure and impact to the mountain wall. It is better to dig three tunnels at the same time.

With the legion channel, three tunnels are blasted at the same time, and the speed of water release is tripled. It can also avoid one-sided pressure on the mountain and make the pressure slightly balanced.

The water flowing out of the three tunnels, after bypassing the three peaks, will merge in the low valley behind and flow eastward. It will definitely form a new lake. If the Cloud Chasing Team had scattered seeds in this generation,

With this drainage of the barrier lake, the probability of germination will be many times higher."

Qiu Feng thought for a while, nodded, and said: "Okay, just as you said, the three tunnels will be excavated at the same time and prepared for blasting at the same time.

Qiu Weiqiang, the armed helicopters returned, including large transport aircraft, to transport rescue workers from the dwarves and goblins to prepare for tunnel excavation.

The livable renovation engineer has already planned the follow-up drainage route. The construction of this temporary camp for the trapped miners can also begin. You can notify the army to continue sending people to send supplies and marching tents. I don’t know what will happen to the flooded mine.

What kind of mine is it? I hope there will be no problems with the miners and the mine."

Qiu Weiqiang said: "Commander, don't worry, the army's dispatch has already been arranged when the armed helicopters are called in. Now we just have to wait for the barrier lake to be drained to rescue this group of miners.
Chapter completed!
