Chapter 427

"No."

The parrot shook his head and said that last time he came, this one had a tower, but now he can't see it.

"Tower?"

Qin Feng was puzzled and asked again, "what was the situation at that time?"

"I forgot. I just remember a gust of wind."

Parrot path.

Qin Feng heard the speech and began to think.

Can it be said that the tower was buried by yellow sand, and then the wind would blow the yellow sand away?

No!

It is reasonable to say that the strong wind in such places will only bring more yellow sand.

Qin Feng simply got up, went to a nearby Sand Mountain and looked around.

Surrounded by sand mountains, it is impossible to tell which is the tower.

but.

He had to go back to the lake and continue thinking.

The people who went around looking for the entrance could not support themselves at this time, and came back here one by one with dry mouth.

When wushijie came back, he saw such a big lake as Qinfeng. When he got there, he jumped into the lake excitedly and had a wild drink. Then he complained to Qinfeng: "we worked hard around to find an entrance, but you enjoyed it here. It's too much!"

Qin Feng ignored him, only thinking about what the parrot said.

Wushijie was ignored again, and his heart was depressed.

Qin Feng asked Professor Ma thoughtfully and said, "Professor, you know more about the desert. Many of the surrounding sand mountains are piled up with yellow sand. The sand is very soft. How much wind is needed to blow the sand away?"

Just after he finished, wushijie couldn't help laughing and shouted, "I said you are really an idiot. This is a desert. If you can blow the Sand Mountain away, it will only bring more sand. Therefore, the sand mountain will only get bigger and bigger, and it won't blow away at all. Do you understand this time? Ha ha..."

"That's right."

Professor Ma agreed with him and said, "when the wind is small, it has no effect, but when the wind is strong, it will bring other sand, so it will not blow away the sand mountain."

Wushijie was even more satisfied and said to Qin Feng, "do you hear me? Even Professor Ma agreed with me. You are good at learning!"

At this time.

Linxueer also came back here, exhausted, and said, "the wind was too strong, and there was almost an accident."

"What's the matter? It's windy?"

Qin Feng wondered.

He knew that linxueer was not far away. There was wind in this area, but it was not big. How could she say that the wind was too strong?

"Well, there may be a draught. I can't even breathe there."

Lin Xueer said.

Tuyere?

Hearing this sentence, Qin Feng could not help but tremble.

He hesitated a little.

He immediately climbed the nearby sand mountain again.

Look in the direction Lin Xueer said, and then observe the distribution of all sand mountains.

last.

His eyes slowly widened and he finally realized it!

"I finally understand!"

Qin Feng opened his eyes.

All the sand mountains are distributed like a maze.

The labyrinth of roads lies in the valleys that turn east and west at the foot of the mountain.

From the shashankou, the wind blows in and out of the valleys. Finally, in a specific way, it gathers together and blows to a place together.

That place is the air outlet!

in other words.

At present, the wind below may be only twoorthree, but when it finally converges to the wind outlet, it will be sevenoreight!

And the sand.

At last, when it reaches the tuyere, most of the sand will be resisted by the sand mountain.

These sand hills are sand "filters"!

"If you guessed right, the Sand Mountain facing the wind outlet should be the entrance!"

Qin Feng muttered.

He immediately went down the mountain and said to Lin Xueer, "take us there. That's the entrance."

"Ah? But I didn't find anything."

Lin Xueer said.

"Listen to me, that's right."

Qin Feng smiled.

Wushijie was unhappy and cried, "Hey, hey, are you very professional? Do you know much about the desert? You don't know anything at all. Why should you listen to you? There is such a big lake here. I don't want to leave the water source."

He said whatever he wanted. Qin Feng didn't pay any attention to him at all. He packed up his things and followed linxueer.

Professor Ma and the others hesitated and decided to follow him.

Only wushijie was left.

no way out.

He had to keep up.

a moment.

The crowd came to the tuyere mentioned by linxueer.

In front of it is a tall but thin sand mountain, surrounded by six sand mountains and three canyons, facing it.

Qin Feng and his gang stopped at the mouth of one of the canyons.

He tried to step forward from the mouth of the canyon.

Sure enough.

The wind is much stronger than that in the canyon.

You can't even walk steadily when you go in.

Professor Ma asked curiously, "where is the entrance?"

"There it is."

Qin Feng pointed to the three canyons facing the thin and tall Sand Mountain, which was like a towering giant stone pillar.

"Stop it!"

Wushijie contemptuously said, "that's a mountain. How can it be the entrance? I think you have eye problems, or you have paranoia?"

Qin Feng still ignored him and continued to say to Professor Ma: "according to speculation, it should be a tower. When the wind is small, for example, now, the sand will cover the tower with the wind, but the wind should be strong. There are three valleys opposite each other, which will form a vortex, so that the sand will not cover too much, so it is' thin '."

"When the wind outside is stronger, the swirling wind will also increase. Through the filtration of this sand mountain, the sand of the wind will be filtered clean. When it blows on it, it will blow all the sand away. When the wind is small, it will be covered by sand again and again."

“……”

Qin Feng finished.

Wushijie had to despise him again, but Professor Ma said: "yes, from the terrain, the analysis is very reasonable. If you don't tell me, I really didn't realize that the terrain here would form this vortex. However, how do you know that there are towers inside?"

"It said."

Qin Feng pointed to the parrot flying in the air.

The crowd was stunned.

Seeing this, wushijie burst out laughing: "hahahaha... It's funny that you believe a bird. Was your brain kicked by a donkey? Hahahaha..."

Smiling.

All of a sudden, I heard two more "PATA" and "PATA".

The parrot he despised poured a pile of bird droppings on his head in the air, flowing down his forehead

"... Cao!!"

Wushijie angrily wants to kill the parrot.

But he is no match for parrots.

Soon he was caught with scars everywhere. The parrot didn't let him go until he begged grandpa to call grandma.

"Now, there are two choices." Qin Feng said, "one is to dig out the gate of the tower, the other is to wait for the greater wind."

"Wait for the wind to come!"

Professor Ma looked at the sky and said, "from the wind speed, humidity and the surrounding landform, there should be a gust of wind here every once in a while. Now it should be coming soon."

"OK."

Qin Feng nodded.

Just then.

Suddenly the crowd heard a roaring sound in the sky!
