After Qingxue climbed a high mountain with Lin 2 frogs, Qingxue carefully watched the layout and trend of the mountains and rivers, and said: "According to my experience, they came along this river, from the upper grasslands, with the migration of the climate, they neither like too cold nor too hot, so they came here, and when the weather is colder, they will go out with the monsoon from the mountain pass on the other side of the plain." ”

Lin 2frog nodded as he listened.

Qingxue then pointed to the high mountain on one side, the top of which was covered with snow, and said, "The peaks of this line block the cold air that tries to go south, as long as we open an opening in this mountain, the cold air comes in, and it gets cold here, they won't stay here for long." ”

Although Lin 2 frog nodded, he also wondered, how can we go and open an opening in the mountain? Use this laser cannon? Then don't burn for decades?

In the next few days, Qingxue and Lin 2 frogs ran to the snow-capped mountain, and Qingxue observed and tested with echoes, found a place and said, "Here, I will use full power to fire a sound cannon!" Use the echo resonance of the valley to destroy the huge rocks on both sides! It gives cold air an opening that can enter! ”

Lin 2 frog looked around and said, "Then the surroundings will collapse!" How do we escape? ”

Qingxue found a place and said, "Dig a pit here, let's hide in the ground!" ”

So they dug a zigzag tunnel, and the entrance to the tunnel was inclined on the back of a rock, taking into account the rockfall, so as to avoid being blocked! The shape of the concave tunnel is neither for beauty nor comfort, but only so that the echo of the sound waves in the tunnel can offset part of the impact of the sound waves, and it is also painted several times with soft mud accompanied by river water and hard mud baked with fire. It also plays a role in weakening sound waves.

When she was ready, Qingxue fired an all-out sound cannon at the mountain!

Lin 2 frogs are hiding behind rocks to block their ears, but they also feel a buzz! The whole person was estimated to have fainted for a few seconds, and when he came to his senses, Qingxue was weakly paralyzed on the ground and beckoned to him.

And this sound cannon, a huge sound, spread rapidly, and the echo in the valley also sounded. Lin 2 frogs didn't care about this spectacular scene, and quickly helped Qingxue into the hole!

The echo of the valley was only loud at first, and then the layers became much more layered, and gradually in some places there was a superposition of crests and crests, and the rocks began to crumble! Lin 2 frogs and Qingxue hid in the hole in the ground, and they both heard the various sounds of cracking, shattering, and collapsing outside synchronized with the echo. Fortunately, in this underground hole, they used a layer of soft mud, and a layer of hard mud alternately smeared several layers to weaken the sound waves, otherwise they were afraid that they would be shocked to death by the sound cannon they made. But even so, both of their ears were badly damaged.

When everything was calm, the two of them climbed out of the burrow, first there was a cold fight, and sure enough, after several peaks had collapsed, it was much colder than before, and then they climbed up the mountains that formed the gaps to watch, and sure enough, affected by the loud noise, and the cold wind that was swishing, the beasts all got up and began to move towards the mountain pass where they were leaving.

And Qingxue and Lin 2 Frog breathed a sigh of relief.

Lin 2 frog said: "Okay, these big guys will not be exterminated!" ”

Qingxue nodded and said, "Our efforts will not be in vain. ”

Then they rested for a long day, and then went back to King Nihod to ask for payment! Although the reward was given to them as promised, the nezumi generally looked at them with more horror!

It was much more difficult to deal with the beasts than the rats, and they had driven them away in a way that seemed more difficult to destroy the mountain. The rats are terrified of both of them! This fear has surpassed the stories that King Nihod had made up for them in the first days!

Of course, their actions have caused the temperature in this plain area to drop by about 5 degrees.

"Hehehe, I thought at first that we were going to ask King Nehod to bring it up, but we couldn't complete the task!" Lin 2 frogs came home and happily enjoyed the cheese and grilled sausages provided by King Nehod!

Qingxue said: "Actually. He thought, we're going to fail, he can build up a higher prestige, and now the rat people are afraid to worship us like evil spirits. He also needs to prove that we are not omnipotent. And if we succeed, he happens to get such a large piece of land, and he has sweetness at both ends. ”

Lin 2 frog shook his head and said, "Really? ”

Qingxue nodded and said, "If we use fire to burn the grassland and slaughter the giant beast, his hands are clean, and he can accuse us in the future after he gets the land!" He did what he wanted to do with our hands. ”

"According to you, he is really a wise monarch?" Lin 2 frog said.

Qingxue nodded, "At least it's much better than what he did before when he governed the Nihods." However, it also shows that with a large population and a huge organization, no matter how wise a person is, he cannot achieve wise leadership. In many cases, it is over without even getting to the bottom of it. ”

Lin 2frog nodded and said: "It makes sense, then we can say that it is perfectly done now!" No killing, no bloodshed, drove away the beasts! ”

Qingxue said: "I am satisfied, they are now afraid of us as if they were afraid of the mountain gods!" It will probably be even more difficult to do it to us in the future! ”

Sure enough, they found that the pits prepared by King Nihod before to hide soldiers underground, or the caves near the trading place where cannons were hidden, were quietly filled up, probably rats, afraid that they would find out, and then rain down disasters or something!

Soon, in addition to King Nihod's official dealings, there were folk stalls next to their trading venues! Specially waiting for the transaction, put it out for the two of them to see!

Haha, this is so funny, Qingxue and Lin 2 frogs are strolling around this stall for the folk people who opened it for them. Some handicrafts. Indeed, if it were King Nihod, their whole system pursued efficiency, and these works of art would not be favored. And these 2-3 rat people have nothing else to do but make these gadgets.

And Qingxue and Lin 2 Frog both thought it was funny, so they bought it back and played with it!

"Actually, they have a spirit of entertainment, they are not like the Nihods, they know how to fight! Expeditionary! Qingxue said strangely.

Lin 2 frog fiddled with a very small house and said, "Yes, it's very delicate, look, you can move here!" Both this door and the small window can be opened. ”

Qingxue said: "Yes, if you think about the history of mankind, art and entertainment are also very important. ”

Lin 2 frog suddenly said: "I have an idea!" ”

Qingxue asked curiously, "What are you doing?" ”

Lin 2 frog said: "Let's build a playground next to the trading ground!" ”
