So powerful! Oh, my God! I regret calling you to run away together, if you were here, it is estimated that 77 Pea Mountain would be safe and sound. Qingxue said.

Lin 2 Frog said: "Their attack was still sudden, and according to Chang Shun, the troops left behind at that time suffered heavy losses. If the two of us were here, it would be dangerous. Let's just think that everything is certain. If humanity is in trouble, we will be buried. ”

Qingxue said: "Don't say that, I told Changshun that they should cooperate with the work of digging the pit, if it is really a defeat, I will definitely call them to leave with you." The green mountains left behind are not afraid of no firewood. And the storage of Pea Hill is carried out by a lot of nodules. Even if they destroy the control room, after all, they haven't burned the entire Pea Mountain, so if it doesn't work, they must retreat first before thinking about it. ”

Lin 2 frog said: "Well, what you said also makes sense. Let's see if we can catch up with it. You can't just run away without doing anything. ”

Qingxue said, "You kind of blame Jack? ”

Lin 2 Frog said without denial: "If you want to evacuate, you should also focus on arming here." Instead of No. 3 Pea Mountain, maybe in terms of defensive conditions, No. 3 Pea Mountain is more suitable, but there are billions of people here. How can you give up? ”

Qingxue said, "I don't know. Maybe he has his own problems. Or maybe he has other plans. ”

"Hmph. No matter what he had in mind. I'm determined to stay here. Lin 2 frog said, but when he remembered Qingxue's advice just now, he said: "At least do your best to defend." Make other plans. ”

3 days passed quickly, and Changshun and they were tired and collapsed from digging tunnels day and night. It seems that the big guys also worked hard to complete.

At this time, the probe detected about 20 rat-man tunnels appeared in the detection range.

Lin 2 frogs gave the order to release the water!

Immediately, water from the underground river filled the entire tunnel, and some of the nezumi tunnels were too close to each other, and they were directly washed through the soil by the current. But a large number of nezumi tunnels are not so coincidental, and they happen to meet frogman tunnels.

Then Lin 2 Frog handed a sleeve with a mouth to Qingxue.

Qingxue put this set in her mouth, and then fired a sound cannon!

The frogman pit and the big pit are good sound transmission mediums after irrigation. The sound waves will form some peaks and troughs due to the vertical and horizontal of different tunnels. In some places, the peaks and valleys are deliberately made to offset in order to form the effect of superimposing the large-level peaks and valleys of the front and back levels.

And when the snow cleared, they felt the whole earth shake!

The tunnels have different rock and soil layers, and the tunnel network they designed has formed a terrible echo resonance!

The detection map observed by Lin 2 Frog shows that all the nezumi tunnels stopped advancing at that moment!

Lin 2 Frog breathed a sigh of relief and said, "Now it's time to increase the detection range." ”

Then he commanded Qingxue and Changshun to carry out a series of modifications, which greatly increased the detection range of the underground situation. At least it can cover the entire underground area of the pea forest. Depths can reach up to 300 meters! Far more than the average depth of the nezumi burrowing.

The increased detection range shows that there are not only 20 pits but 1,100. And since that day Qingxue released the sound cannon, he has not advanced.

On the rat man's side, Cludo found that there was an inexplicable shock that day, and then reported that all the excavators in the tunnel were either dead or crazy! The rats were so frightened for a moment that they didn't dare to burrow anymore.

On the one hand, Cludo has adopted the method of raising rewards to stabilize people's minds and boost morale. Larger-scale tunnelling is then started in 3 directions. According to the information he collected, it should be the frogman's sound cannon, which caused the rat man digging the tunnel to be shocked to a considerable extent! So this time, each tunnel will open a hole to the ground at a distance, so as to disperse the vibration waves, a tunnel according to the length, such holes are at least dozens. This can greatly reduce casualties.

Moreover, it was divided into three directions to advance and excavate, and it also avoided the annihilation of the whole army.

But after they did this, as they approached Pea Mountain, there was another tremor like before. However, this casualty was only 1/100th of the last time, and Cludo felt that this loss was completely acceptable, so he ordered his troops to speed up the digging of the pit.

This time the vibration was undoubtedly Qingxue's sound cannon, but this time it didn't succeed in stopping the rat-man's tunnel. So Lin 2 Frog began to use the second trick to electrify the water in the tunnel. And from here in the control room, some magnetrons will be activated.

The entire frogman's defense tunnel has become a complex electromagnetic field of electromagnetic alternation.

After adjusting various parameters, Lin 2frog walked up to a supercapacitor switch, took a deep breath and pressed the switch.

With this buzz!

The whole system worked, and Lin 2 saw that all the tunnels had stopped moving forward again.

But what Cludo received was that the soldiers in the tunnel were all wiped out again! And this time it was even worse, half of the soldiers were red all over, as if they were already cooked, and the death was very terrifying. The other half of the fighters showed the cause of death due to symptoms such as cardiopulmonary failure.

Cludo had no choice but to stop digging.

Lin 2 Frog saw that the progress of the tunnel stopped again, wiped his sweat a little and said, "I hope you don't want to be stupid and want to come for the third time!" ”

Qingxue asked, "What will happen if you really come here?" ”

Lin 2 frog looked at him and replied seriously: "If you come again for the third time, it will be even worse than this time!" ”

And the frogman warriors such as Chuanshun erupted in cheers!

They thought they were taking on a task that could not be accomplished. I even felt like I was abandoned here and waiting to die. Who knew that now the situation was reversed, and they resisted the attack of the nezumen.

Another 2 days passed, and Jack came.

He had received the news that Lin 2 Frog and Qingxue had returned and successfully thwarted the nezumi digging operation.

Jack cried when he saw Qingxue and Lin 2 frogs!

"I'm sorry for you two bosses." Jack cried, "I failed to protect the children and Pea Mountain." ”

Qingxue could only comfort him when she saw him crying miserably: "Don't be like this, you did your best." We understand that, too. ”

Jack quietly glanced at Lin 2 Frog, seeing that he didn't react, and then cried: "They attacked too suddenly, our main force was out to deal with the heavy mining team at that time!" They raided 77 Pea Mountain with poisonous smoke, and the entire forest was full of smoke, and they couldn't see their fingers. ”

Hearing this, Lin 2 Frog sighed and said, "Indeed, no one thought that they would attack like this. ”

Seeing that Lin 2 frogs had the meaning of comforting himself, Jack calmed down a little, wiped his tears and said, "At present, there are still tens of thousands of young frogmen who have been captured by them. I've come to you to discuss how to free them. ”
