But the signal of the hostage they were most eagerly waiting for was not discovered for a long time. The signals received continuously, Lin 2 frogs identified them in the underground three-dimensional model, but with more than 3,000 groups of signals coming one after another, the frogs found that the scale of the original rat people was so huge.

The scale of the underground city is beyond imagination, and the territory has long covered the underground of the previous 10 cities, and the area where they were hiding back then has also been completely underground urbanized. This part is at least 10 times the area of the previous 10 cities. Moreover, the tallest building in the previous city was only 5 floors, and the depth of the underground city of the rat people could reach 200 meters!

It is clear that there was a good control of the population during the time of King Nihod, but this is not the case with the current Cludo. In line with the principle of having more children and fighting, Yokludo did not have any population planning measures in place.

And the 3000 group of Da Da is still changing positions with the rat people, and then sending back the identification code of the new place. Lin 2 frogs, they almost drew a 3D panorama of the rat-man underground kingdom. Due to the large identification of 3,000 groups, the underground road system of the Nezumi Kingdom has even been outlined.

Qingxue wiped her sweat, looked at the analyzed data, and exclaimed: "They actually have a population of 10 million people here!" ”

Lin 2 frog also said: "No wonder they dare to take the initiative to attack when they are so far behind in science and technology and equipment, they really don't care about casualties!" And in a few days, it is estimated that the comparison with our population will reach 1 to 10,000! When the time comes, even if you use advanced weapons, you will not be able to defeat the numbers. ”

Qingxue said: "But I haven't found any trace of the children!" ”

Lin 2 Frog said: "From the current point of view, there are about 3 places in the entire underground kingdom of the rat people that are without information. "Lin 2 frogs are identified on the complex three-dimensional image of the underground kingdom of the rat-people.

Qingxue said: "That is, they keep moving on the rat people, and all the rat people have not been to these three places. All three of these sites are surrounded by barracks and other facilities. It should be heavily guarded something! ”

Lin 2 frog said: "But it is heavily guarded and heavily guarded, and they will also have to eat." Then as the person who delivers the food goes in, it should still be possible to get in if it is attached to the person who counts and stores it. Why haven't you ever been in? ”

Qingxue said: "If you are holding hostages, you may not need to go in. But will the children be scattered in 3 places? ”

Lin 2 frog said: "It's possible. First, there are 50,000 frogman cubs, which is not a small number, and second, the quagmire environment they need may not be so easy to find. The third is that in case we attack one place and rescue the hostages, there are still two places to respond. ”

Qingxue scratched her head and said, "My good man, how can this be saved." ”

Lin 2 frogs are also meditating.

When there were no new signs for the big men, Lin 2 Frog gave them the order to return. Then he thought about how to rescue the hostages in these three places. If you only save one place, you will inevitably startle the snake, and the other two places will do special treatment, and it will be even more difficult to save them again. However, it is not easy to raid three places at the same time, different depths, different areas, and heavily guarded places.

Lin 2 frog thought hard for many days, but he didn't think of a complete solution.

Qingxue came to Lin 2 frog on this day and said, "Why don't we attack the enemy and save it?" ”

Lin 2 frog said, "What do you mean? There seems to be a lot of everything in the Nezumi Kingdom. Where do you think they will be saved? ”

Qingxue said: "In such a huge underground kingdom, ventilation is the most important. Attack their ventilation system! ”

Lin 2 Frog said: "I have also considered this, but they have at least hundreds of thousands of ventilation holes, and in the entire rat-man country, the density and complexity of the ventilation sub-network is still more than their road traffic system!" How do you want to attack their ventilation system? ”

Qingxue said: "Artificial rain! Their entire kingdom is underground, which is not conducive to drainage, and they currently have an impervious rock and soil layer underneath them, and an underground river network underneath them. They only penetrated a few places and used them as drinking water for the entire kingdom. So the amount of rain that rains only needs to exceed the natural absorption of the place where they live. Their cities will be flooded. Moreover, the water level of the underground river is rising, which will form a double pressure on them! ”

Lin 2 frogs clapped their hands and said, "High! When the time comes, they will only be running for their lives, and there will be chaos, and we can attack 3 places at the same time! ”

Next, they began to study the topography of the entire large area.

The plains below the steppe beasts they drove for King Nihod were already almost entirely a city of rat people, and if there were a few more openings in the northern mountain range, more cold air would move south, colliding with the warm and humid air currents from the north, and heavy rainfall would be formed.

At the same time, taking advantage of the monsoon climate, the rainy season was also ushered in in about a month.

Lin 2 frog and Qingxue are very accurate to mark a few mountains, if the mountain is opened here, it can not only form heavy rainfall, but also form a high-altitude vortex airflow, attracting the surrounding water vapor, and then there will be super rainfall that has not been encountered in thousands of years or even 10,000 years! The entire underground kingdom of the nezumi will be completely submerged!

Then Lin 2 Frog and Qingxue studied how to open the mountain.

But at this time, the nezumi came to contact, and the representatives of the nezumi asked the frogman what he was willing to pay, and they demanded that the frogman be evacuated from the current 2 pea mountains!

Qingxue said: "They are lions with big mouths!" If we lose these two barriers, won't there be no place for us? ”

Lin 2 frog said: "Call the people who go to negotiate, sit on the ground to pay the money, and bargain with them." What we really want to implement is the heavy rainfall blow of the flooded 7th Army! ”

But within a few days, the rat man really lowered his requirements and asked the peas produced in Pea Mountain to be exchanged for hostages, although the number of requirements was a lot, but at least it was a huge concession compared to before.

Qingxue was a little embarrassed: "According to the current conditions of their opening, the output of our two pea mountains can bring back all the children in about 10 years." ”

Lin 2 frog said: "There is still half a month before the best time to create a super heavy rainstorm. Are you ready to give up? ”

"Although we can save the children by creating a super heavy rainstorm, it will cause millions of casualties to the rats. Is the killing too heavy? ”

Lin 2 Frog sighed and said, "Is there any room for relaxation for the 2 clans at present?" Both sides are left with a life-or-death choice. ”

Qingxue recalled the situation of the deal with Holmes back then, although they often quarreled, but the two sides were still peaceful, and they helped their main city fight the flood before, when Jack and they were still very young. Hey, there's no going back.
