Because there are volcanoes under the seabed, the surface of the earth is the boundary between the underground and the aboveground, and a temperature difference can form, which leads to the formation of fog.

It's like a person wearing glasses who suddenly enters the heating room from the outside of the cold weather, and a layer of mist will appear on the lenses!

In this way, the reason for the formation of fog in the Misty Forest is well explained.

As for the oasis, it is because it is in the center of a volcanic eruption, and the soil formed by the cooling of the magma is the most fertile, so the vegetation can grow vigorously.

The pond in the center of the oasis is slowly accumulated after the condensation of water vapor, and the point is that it is low-lying, otherwise the water would not have converged there.

Xiao Ning nodded, boasting that he had brains.

However, he found that even if he knew the cause of the formation of the Misty Forest, what was the use? at most it was just an extension of his knowledge, and it had no practical meaning.

"Let's go. Xiao Ning beckoned to Chen Xue, intending to leave here, the volcano would completely erupt in a while, and he was afraid that he would be affected.

"Oh. Chen Xue glanced in the direction of the Misty Forest again and followed Xiao Ning down the hill.

"Not true. Suddenly, Xiao Ning stopped again and turned back, causing Chen Xue, who was following closely behind him, to collide with him and bump into him.

The little wolf cub Dumb couldn't stop his footsteps, and hit Chen Xue's leg headlong.

Now it's okay, Chen Xue's center of gravity shifted, her body tilted to the side, she tried her best to straighten her body, but she accidentally bumped into Xiao Ning's moon boast.

Xiao Ning took a deep breath, his eyes widened, it really hurts!

"I ...... I didn't mean to, who told you to brake suddenly. Chen Xue realized her embarrassing move, and immediately straightened up again, distancing herself from Xiao Ning.

"It's okay, it's going to hold on. Xiao Ning inhaled the cold air and waved his hand.

Xiao Ning then said: "On this desert island, there should be similar places, maybe we can build some secret strongholds here, in case something happens in the future, we can come here to hide!"

Xiao Ning's idea was simple, find a similar oasis surrounded by mist, build a few warehouses inside, and stock up on some food.

In the future, if you are in trouble, you can come here to take refuge, or if you have something to do, it can be used as a supply depot on the way!

It's just that Xiao Ning doesn't know where other similar places on the island are, but he believes that he should encounter them again.

"Let's go. After Xiao Ning told Chen Xue what he thought, he continued to go on the road with Chen Xue.

The two walked together for three days and three nights, and did not find any clues about the helicopter.

Xiao Ning has already lost some patience, and so is Chen Xue, now it depends on who brings it up first to go home.

Day after day, five days passed at once, and it had been half a month since they left the Ilyin.

Xiao Ning sighed, and finally said on a sunny afternoon, "Shall we go back?"

"Good. Chen Xue slowed down for a moment, then nodded.

Now, Chen Xue's idea of looking for a helicopter to leave the desert island has gradually faded.

In fact, people are like this sometimes, once they can't see hope, that thought will slowly fade until all thoughts are gone.

"This trip is not a harvest at all, at least we have found some crop seeds that can enrich our food variety. ”

Looking at Chen Xue with a depressed face, Xiao Ning said cheerfully.

"Hmm. Chen Xue nodded expressionlessly.

"Let's go, go home!" Xiao Ning stretched.

But at this moment, there was a rumbling mechanical sound in the sky, accompanied by the air waves generated by the rotation of the propellers, blowing the two of them flying wildly.

"Hide!" Xiao Ning was stunned for a moment, then startled, and pulled Chen Xue to quickly hide under a leafy tree.

Xiao Ning didn't expect that when they were about to go home, they accidentally met a helicopter!

In this way, they have always been in the right direction, and if they go a little further, they may be able to see a helicopter!

The helicopter did not stop, whistling away above Xiao Ning and Chen Xue's heads.

"This helicopter is not the one I've seen!" Xiao Ning said with some excitement.

This proves that there is more than one helicopter!

However, Xiao Ning's face immediately became solemn, and the situation on the desert island was even more complicated than he expected!

First motorcycles, then helicopters, and then what will come out next? tanks, rocket vehicles?

"What now?" asked Chen Xue after the helicopter flew away.

"Keep going and you should find other helicopters. Xiao Ning said.

He wondered if there was an airport in front of him that was dedicated to parking planes.

Xiao Ning even launched his imagination, this desert island, shouldn't it be a play arranged by a certain director?

Xiao Ning and Chen Xue decided to continue their exploration.

The two walked for another day and night, and finally found some tire prints on the ground!

Looking at the depth of the tire prints, it should be a small car!

Sure enough, after motorcycles and helicopters, there were cars!

These things shouldn't have appeared on a desert island!

Xiao Ning and Chen Xue walked along the tire print, all the way, the tire mark is very long, the two of them have walked about five kilometers, and the tire mark has not been broken.

"I can't walk. Chen Xue was so tired that she couldn't walk.

"Then let's get some rest. Xiao Ning nodded, cleaned up a clean place for Chen Xue, and asked her to sit down and rest, while he and the little wolf cub went around the neighborhood.

Xiao Ning had a hunch that he was approaching his destination, and he didn't dare to let his guard down.

Rustling footsteps sounded, and someone seemed to be coming this way.

Xiao Ning immediately pulled up Chen Xue and hid behind a big tree.

The footsteps were getting closer and closer, and Xiao Ning poked his head out and saw the person clearly.

The people who came were two people with loaded guns and military clothes, who looked more like mercenaries.

The two of them found a big tree and leaned on it, then quickly took out their cigarettes and smoked them.

The two of them snorted cigarettes, spit out smoke rings, and chatted with laughter.

"It's nearby!"

Xiao Ning hooked the corners of his mouth, they should have arrived at their destination!

It's just that they haven't seen the destination yet, so what's in there, helicopters, cars, and other high-tech stuff?

Xiao Ning waited until the two of them finished smoking before walking out from behind the big tree.

Xiao Ning was pleasantly surprised to find that these two people left the cigarette box behind!

Xiao Ning ran over and picked it up, thinking it was empty, but there was still a small half pack of cigarettes left inside!

Xiao Ning put the cigarette into his pocket as if he had found a treasure, and then touched it towards his destination.
