The night is as cool as water.

The coast, which was still hot during the day, began to plummet after nine suns had set.

The sand on the shore doesn't store much heat, it's hot during the day and cold at night.

On the contrary, the seawater, which is much larger than the heat capacity, is still steaming at this time.

And many sea creatures hidden in the sea during the day began to climb up to the beach one by one in the slowly orderly sea water at night.

Hello!

Xu Yan and Huang Wenbin hid in a sand pit not far from the coast and started a fire with some dead branches and fish bones.

It's just that, a little frightening, the flame that ignited turned out to be green.

Although the heat emitted is still warm, it inexplicably makes people's hearts feel a chill.

"Brother Yan, what are we going to do next? Are we just going to stay here for three days until the end of the exam?"

Huang Wenbin curled up in the hole, looking lazy and tired.

Indeed, since he entered this world exam today, Huang Wenbin has been running for his life.

His nerves were completely in a state of high tension, and it wasn't until he met Xu Yan that he was able to breathe a sigh of relief, and finally he could take a nap safely.

However, for this completely unfamiliar world, Huang Wenbin knew that they still couldn't completely relax their vigilance.

Even if it is safe enough at the moment, as long as you have studied high school geography, you should know that in such a desert terrain, although the scorching sun during the day is a huge threat to life, the real deadly danger will appear at night.

Not only the low temperature at night, but also the monster beasts that only come out to forage at night.

"Naturally, we can't sit still like this, this world must be more than that. If we want to get a high score, we have to get out of this desert and find the human civilization in this world......"

Xu Yan was roasting a piece of fish demon beast's meat while thinking about the limited information he had obtained from the examiner today.

Before leaving, all the candidates actually reviewed the points rules of this exam.

In order to come out on top in this exam, there are three areas of scores.

One is the survival score, and the exam time is three days in total.

In this world, the longer you survive, the higher your survival score will be.

The second is the experience score, and the admission ticket they carry with them is an energy detection device.

Not only can we eject them from this world in time when they are in danger, but it can also record all the high-energy organisms that each candidate encounters in this world at all times.

In other words, the entire examination system is to judge what kind of experience candidates have experienced through this admission ticket.

For example, if Huang Wenbin and Xu Yan encounter a shell whale, the admission ticket will accurately record the energy fluctuations of the shell whale, and after the exam is over, it will be fed back to the system to prove that the two of them still survived or even killed under the attack of the demon beast around the sixth grade.

In this way, the experience score that the two of them can get will be very high.

The last type is the intelligence score. Every candidate who enters this world is a natural intelligence officer, tasked with exploring all kinds of information in this world for mankind.

This information includes not only the geography and biological distribution of this world, but more importantly, the information about human beings in this world, or human-like intelligent beings.

If you can get this information, you can get a higher intelligence score.

For now, Xu Yan and Huang Wenbin's survival scores cannot be judged, but the experience scores can be said to be quite high.

Just ask me, the highest level among the candidates is only the third rank, how can they escape under the attack of the sixth-rank demon beast? let alone fight back.

Only like Xu Yan and Huang Wenbin, under the favorable circumstances, with the help of coastal terrain and sandy beaches, can they trap and kill the shell whales.

"Finding the human civilization of this world? This is not an easy task! Didn't you say it before, Brother Yan? You walked for a day, and you didn't get out of this desert? We only have two days left, and if we leave the coastline, it will be even more difficult to obtain energy and food!"

would say this, not because Huang Wenbin is timid and incompetent, but because he came from the end of the world and experienced a more harsh living environment, so he is more able to predict the difficulties and situations that may be encountered in the future.

"Since we are going to find out this information, there must be a way. Moreover, as long as we take the shell whale carcass with us, it is very enough for us to replenish our physical strength for two days. ”

Xu Yan's eyes looked at the beach, and the shell whale was almost gone.

On the contrary, it was the sea creatures that climbed ashore in the seawater, and their movements made Xu Yan and Huang Wenbin puzzled.

"Brother Yan, what are those crabs and shrimps doing? and ...... Why are the fish coming to the beach? Are they not afraid of the sand now? It seems like ...... They're all eating sand all the time!"

Huang Wenbin saw it very clearly, many aquatic monsters in this sea water took advantage of the night to climb to the shore to eat sand.

"During the day, these sands absorb a lot of the essence of daylight. But it is incomparably scorching, and it is the nemesis of these aquatic monsters. However, at night, they all come to eat the sand again...... Wait, look at the red crab on the left that is missing a pincer, and its pincers seem to be slowly growing back......"

Looking at it, Xu Yan was also very surprised, these sand that looked ordinary seemed to be like a tonic to these sea demon beasts at this time.

"Really. And the fish monsters, I remember clearly, they didn't have carapaces on their backs. Just by eating sand, the result is slowly growing a layer......"

When Huang Wenbin saw this, he suddenly thought, "By the way, the heavy carapace on that shell whale should also grow by eating these sands, right?"

"I seem to know something. ”

Xu Yan looked up at the soft moon shining in the sky, and then looked at his status bar, there was no longer a sign of the state of detachment, so he said thoughtfully, "The nine suns during the day are constantly scorching everything, on the one hand, releasing a powerful thermal energy, and on the other hand, constantly absorbing the qi and blood power in the living organism. ”

"The heat energy can be absorbed by this sand under our feet now, the same ...... If this sand is used as the material for the carapace, then even if it is exposed to the nine suns, it will not be easily swallowed by them......

Through this series of observations and analysis, Xu Yan probably understood how the power of the creatures and monsters in this world came from, and how they were preserved and cultivated.

However, at this time, Xu Yan and Huang Wenbin suddenly heard an earth-shattering roar......
