"Hide!" Petru trotted a few paces first, and with a fish leap ducked behind a nearby reef.

This is the tidal flat of the island, with golden sand and many high and low brown reefs scattered around.

It has to be said that in the face of danger, Petru, who had been a mercenary and a pirate, reacted extremely quickly, and as soon as the howling sound started, he issued a warning, and at the same time his body was already moving.

By the time Aoki and Su Huilan hid their bodies, Petru had already set up his rifles, loaded his bullets, and looked like he was on full alert and ready to go to war.

Su Huilan said softly: "Don't be so nervous! ”

Petru took out a military binocular, looked at it carefully, and said: "Although you are all masters, I still advise you not to be careless, and don't underestimate the combat effectiveness of savages." I fought in the African jungle against the most primitive tribes, and their weapons looked backward, but they were amazingly combative. They only need three people to stab a male lion to death with a spear combination; Quenched arrows can render a boar ineffective for ten seconds; The most terrible thing is the blow arrow, which is silent, has a range of up to more than fifty meters, and is better than a sniper rifle in the jungle. They may not be as physically strong as we are, but I can guarantee that if they race in the jungle, no one can outrun them, not even the World Champion. ”

Although Su Huilan knows a lot, she has been led almost all the way since she came to the South Pacific, but after all, she has never participated in the war, and she does not dare to be blindly arrogant about this kind of thing, and the only one with combat experience here is Petru, so she no longer speaks, but waits for Petru's reconnaissance results.

The howling of the island continued one after another, as if it were transmitting some kind of signal.

Petru observed for a moment and said, "It doesn't seem to be coming for us." ”

He probably also felt that what he had just said was a bit serious, so he turned his head and smiled at Aoki and Su Huilan, threw the telescope to them, and said, "Those tribes in Africa fight every year, and the situation here shouldn't be so serious. ”

Aoki said, "Don't be careless yet, what I'm most worried about is how much these people know about spiritual power. It stands to reason that a race that has lived around a strong spiritual energy field like Tabb for generations will inevitably evolve corresponding abilities, such as immunity to mental hypnosis, in that case, it will be difficult to deal with! ”

"Psychic hypnosis immunity?".

"It's very likely that the spiritual energy field here is too strong." Aoki looked up at the lush and verdant mountains and forests in the distance, "After staying in such an environment for a long time, people are easy to hallucinate, and ordinary people live for a year and a half, and there are only two final results." ”

"Those two?"

"One is schizophrenia, always between fantasy and reality, and I can't even tell who I am." Aoki was suddenly stunned when he said this, feeling as if he was talking about himself, and couldn't help but laugh self-deprecatingly.

"What about the other one?" Petru asked.

Seeing that Aoki did not answer, but fell into deep thought, Su Huilan said:

"The other is adaptation to the environment, which can also be called evolution. Organisms generally have this ability to adapt, and the evolution of species is largely caused by changes in the living environment. For example, noise can affect the central nervous system, and if a person lives in a new environment full of noise for a long time, it will cause the excitatory and inhibitory functions of the cerebral cortex to become dysfunctional, causing neurasthenic syndrome, and may further affect the cardiopulmonary function and endocrine system. But as soon as you adapt to this environment, the body adjusts itself, and the brain automatically ignores this type of noise.

For example, the beach here, with its endless tides and wind and waves, is one of the noisiest places in nature. If you bring animals that live in the desert or plateau here, their bodies will show obvious symptoms of discomfort. But most animals and people adapt quickly, partly because of our large range of motion and the sound of water is a common sound, and on the other hand, our ancestors all climbed up from the ocean.

If you think about it, a large city is not in a noisy environment every day, but after several generations of adaptation, as long as the rhythm of the city does not change drastically, people have fully adapted to this particular noise, and even evolved to make noise more efficient in sleep and learning. ”

Petru understood, and as a soldier, he immediately drew inferences from one another: "If there is a nuclear war, do you think that human beings will evolve the ability to adapt to nuclear radiation?" ”

Su Huilan smiled: "I think it is more likely that cockroaches and rats will survive and evolve." ”

Petru and Su Huilan watched the movement above as they spoke, while Aoki closed his eyes and carefully felt the powerful spiritual energy released from the island.

The energy here is obviously many times stronger than the one on Tubuai Island, because it needs to be within a few hundred meters of Tabb to feel it, and the energy field here obviously covers the entire island. The key is that it is not known how big this island is, according to Su Huilan's analysis, the area of the primitive tribes on the island cannot be small if they want to survive.

The whistling of the wild men gradually weakened, and for a moment they could not be heard, and I did not know if they had stopped, or if they were far away.

Confirming that there was no danger, Petru got up and dragged their rubber raft over, found a gap between the large rocks that stood up, and stuffed the raft into it and hid it.

He looked at the vast sea and said, "The boat is gone, this raft is the only tool for us to leave the island, if we lose it again, we can only chop wood to make a raft." ”

At this time, Aoki opened his eyes and said, "The ship should still be there, but we can't see it." ”

"Why?" Petru asked.

Su Huilan heard Aoki's prompt, thought for a while, and immediately remembered a story:

"When Columbus landed on Waltering Island, the Indians did not see his three-masted galleon, St. Mary. I've always told it as a philosophical story at Columbia, and now it seems that maybe there was something else going on at the time. ”

Aoki remembered that he had told the story to Apricot Hu in order to make her understand that human cognition would not exceed her own memory. The development of human society has always followed a slow process from quantitative change to qualitative change, and any point of real innovation that has never been made before is earth-shattering and will have a huge impact on society, and this kind of person has become a great man. But even so, these innovations have not transcended the bottleneck of human cognition, for example, human beings can use various mathematical methods to calculate the scale changes of the entire universe, but they can never imagine the universe in four dimensions and higher dimensions, and cannot know what the universe looks like outside the universe.

Of course, Aoki didn't know Columbus, and he didn't know the truth of this legend, he just used this legend to illustrate a truth. And now that Su Huilan mentioned this, he felt that there might be something else going on.

"The tabp on the island of Tubuai is an energy cover, although the distribution of spiritual power is not even, the closer to the center of the tab, the stronger the energy, but it obviously has a dividing line."

Aoki tapped a few steps on the beach, leaving his footprints on the soft sand, "It's kind of like the border of a dream, vague but distinct." The island's tabb also has such a boundary, but it is much larger and covers the entire island. ”

Su Huilan thought thoughtfully, squatted down and gently dusted the sand on her pants. When I heard the howling of the savage just now, I hid in a hurry, and there was a lot of sand on my body, especially on my feet, but fortunately I wore jungle combat boots. But when she casually looked at Aoki's feet, she was surprised to find that he was wearing a pull board, and there was not a grain of sand on his feet.

Aoki said: "The spiritual energy is stable now, and when we are at sea, it fluctuates a lot, which may be related to those weird fogs. As you remember, the next time there was fog, we could come to the beach and see if our boat was there. ”

At this moment, a gunshot suddenly rang out from the depths of the mountain forest.
