If there is a criminal police here, you can judge the gender and weight of this person by the size and depth of the footprints, although the sea area here is still considered the territory of Daxia, but it is already very close to some countries in the South China Sea, and you may be able to judge the country according to the shoe prints.

It's a pity that no one has this skill.

It's a shallow sandy beach, covered with a coral reef that has probably never been set foot on for thousands of years, and these footprints are on the gravel, and the algae and organisms on the reef are affected, and the creatures seek to avoid the harm, so that what may have been a shallow footprint becomes clear.

They are new and will not last more than a day at most.

Visually, the footprints are irregular and messy, and it should not be a single person, but a group of people have landed here, and now there are no ships on the sea.

"Everyone, has anyone been to this area?"

Yu Yusi turned around and said to everyone, although it is unlikely, it is better to ask.

Everyone shook their heads, everyone left according to the arrangement, this island is deserted, it's not good to fall behind.

"There's no one in the class who is that size."

Mu Ning said, his eyes were sharp when he opened his pupils, and they reached the level of visual inspection that can only be achieved by perverted-level foot control.

They have feet about the same size as these footprints, but there are differences in details.

"Maybe there are fishermen who come to the island to rest, and this island is not your home, do you take care of it too much?"

Li Ang has been with a cold face from morning to now, and his eyes have been looking at Mu Ning and Yu Yusi from time to time, his eyes are full of resentment and anxiety.

What did they do in the woods in the early morning? They seem to be more familiar than the rest of the class, what is their relationship?

The hateful newcomer is so arrogant!

Mu Ning glanced at him, he didn't understand why this classmate had such a big opinion of him, and he didn't bother to think about it, in comparison, it was the strange footprints on the beach that made him care.

If anything, the ability to sophistry for truth has a description that can perceive falsehoods, but he only suddenly feels something, and this ability is not focused on foreknowledge in the first place, and it is normal to be wrong.

"Just to prevent possible dangers, the ill-intentioned people at sea are more fearless than those who commit crimes on the road."

Mu Ning said.

"It's also possible that the expedition team came to this place first...... Anyway, there are no ships moored here, and submarines are even more impossible, and the orcas hate that thing. ”

Yu Yusi said that Heiyan Island is clearly marked on the map, and it is not a desert island that no one knows, and it is normal for people to go ashore.

In the same way, this island is located between several countries across the sea from Great Xia, and those countries are not peaceful, and some criminals have fled overseas, so it is necessary to be cautious.

"Anyway, even if other people have been on this island, they should have left by now, and I'll talk to the professor about it when I get back to camp in the evening."

Yu Yusi also used a detector to survey the nearby area for safety reasons, and found no trace of other people, so that everyone could rest assured.

Since there was no situation, Mu Ning didn't say anything more, just when this was a small episode.

Wearing diving goggles and locators, Mu Ning put on special fins and went directly into the water, and there were special communication devices and alarm devices on the diving goggles, which were connected to the shore sounder and computer.

As soon as a large sea creature approaches, the siren warns the person entering the water through a communicator.

The beach is huge, and you have to split up to find more resources, but of course it's not good to spread them all out, and most people are in pairs.

Mu Ning looked at Yu Yusi and He Yang, who had been following him into the water, and fell into deep thought.

"What's going on with you two?"

Mu Ning looked at the two henchworms suspiciously, and used the liaison to talk to the two people.

"You know me, extraordinary ability is useless, there is no self-protection ability at all, only you are strong enough to protect me, I will definitely follow you."

Yu Yusi was a little inexplicable, as if Mu Ning had asked a very stupid question.

“？”

Mu Ning was puzzled, was he asking this question, Yu Yusi was the same person as the shareholder of this event, a well-known landlord and old wealth, and she was not short of money at all, what did she need to do in the water? According to her contribution to the class, she will have no opinion on how many percent of the corals she picks!

He set his eyes on another person again, this guy is even more outrageous, obviously he only met yesterday, and he even posted it, Mu Ning didn't show any intention of forming a team.

"Huh? Didn't you go into the water together? I see everyone else doing that.

He Yang had a confused expression on his face as to how I knew and no one informed me.

Oh, is it because it's too unsociable, so it's out of touch with thinking?

Mu Ning sighed in the water, and bubbles floated in the sea.

Yu Yusi is very satisfied with this three-person lineup, she has nothing to say about Mu Ning's combat power, the people of the hard dragon descendants are all good men, He Yang is also very strong, the genetic sequence is quite high, what is it, wait, it seems to be ......

The elements of the fire system make the sequence? What is this good for in the water?

Damn, this guy might be more wasteful than me in the water!

Yu Yusi looked at He Yang with wide eyes, this person looked honest, and his heart and eyes seemed to be not much at all, and he knew that he wanted to have his thighs.

Whatever, as long as you don't bother her to do that, she came to this island so hard and hard, of course, there are other purposes.

Some things can be bought with money, some things can't, you can only do it yourself, this kind of class activity is just to help students make money, to say that you can do a lot of activities for money, you don't have to go to an isolated island.

The reason for this, of course, is known only to her.

"I have the most advanced exploration equipment, I'm very good at finding resources, I can't go wrong with it!"

Yu Yusi went into the water with a portable bag containing various equipment and even an oxygen tank.

"Me too...... I can help them carry the sacks! ”

He Yang was not to be outdone.

Several people pressed their communication masks, although they were close to each other, but they were radio waves, and they were spitting bubbles when they spoke.

Mu Ning gave them a middle finger, floated up to breathe, and said a few words to let go of the gas, but there were three people who took care of each other and no problem.

The bottom of the shallow water is also sand, and the sunlight shines down from the sea above, turning the beach at the bottom of the shallow sea into a light green water, and the water is so clear that you can directly see crabs and small fish swimming on the sand three or four meters below.

Coral reefs can be found everywhere here, they are the home and food of these underwater creatures, and they are the lowest part of the food chain here.

"We're looking for coral branches in the shape of a white tower, and the corals here are all the color of algae, all of which are the most common species, and they don't contain anything extraordinary."

Yu Yusi said.

Everyone has looked at the appearance of extraordinary coral branches on the Internet, but it is difficult to find white corals.

"There are environmental factors for the survival of organisms, and polyps are the lowest level of extraordinary organisms, and their growth depends on the concentration of extraordinary substances in the region, and they ingest extraordinary substances from seawater and soil."
