Wei Hongjun's profession quickly won over a group of fans, especially the two girls, Yuan Fan and Mu Fanqing, who were originally hardcore lovers of horror and supernatural stories, and were very interested in this kind of mysterious sacrificial ritual.

The other companions were not much calmer than the two, and with Professor Wei's introduction, the mystery of Dibron Island was gradually revealed.

"I'm afraid that even the aborigines don't know much about the true and false folklore about Dibron."

"On the one hand, the aborigines lack knowledge and do not understand scientific knowledge such as meteorites and plate movements, and secondly, the underworld stone can indeed make people hallucinate."

"With false rumors, Dibron has become more and more mysterious."

The reason was made clear, and the fog that cast over the hearts of all people was lifted.

"Did you say there was extraterrestrial life in the universe?"

The meteorite theory has sparked a lot of discussion, and the topic has jumped from sacrificial talk to the discussion of extraterrestrial life.

"I don't think Earth is the only planet with intelligent life. The universe is like a calm lake, and the evolution of life is like the occasional ripple on the surface of the water, some fleeting, some lasting and long-lasting. ”

"Life is easy to obtain, but civilization is hard to achieve."

"There are many opportunities to form life, but there are very few lives that can withstand the test and survive for a long time, and gradually form a civilization."

"You mean to say that there is life on many planets?" Mu Fanqing asked.

Wei Hongjun said solemnly: "Yes, I think so. ”

His words made most people think deeply. How life came into being, how civilization developed, and how many civilizations appeared on the earth are still debated. Extraterrestrial life is a topic that everyone is talking about.

Life does not mean civilization, and when humans begin to look beyond the Earth, they hope to find other civilizations in the lonely star field.

"Extraterrestrial life and extraterrestrial civilization are two different things."

Scientists have found low-level life on meteorites, so it is still debated whether life on Earth originated on Earth itself or whether meteorites fell.

Wei Hongjun added: "It is inevitable for human beings to explore outer space. ”

Yun Tianming asked suspiciously, "Then why do you say that we haven't found any signs of extraterritorial civilization yet?" ”

"And what do you think are the signs of extraterritorial civilizations?" The professor asked rhetorically.

Yun Tianming thought for a while and said, "Light." ”

"No, it's a creation." Xiuxiu next to him retorted.

Unnaturally generated creations!

For example, a straight line is located in the Nazca Wasteland in western South America and southern Peru, and there is a line that stretches for several kilometers on many grounds;

For example, a standard quadrangular pyramid, distributed in pyramids in Egypt and the Americas;

Like the Great Wall winding between the mountain tops and dangers;

Such as artificial satellites densely packed outside the atmosphere.

"You're all right and you're not right. Different civilizations have different trajectories, human beings have learned to use electricity, and the fact that they have built lamps does not mean that other civilizations have such inventions, nor does it mean that we cannot see lights when observing a certain planet, it means that there is no civilization on that planet. ”

Everyone was confused, and their eyes widened in anticipation of the professor's next words.

"First answer the tour guide Yun Tianming's question."

Freeman Dyson put forward a theory in 1960: when human civilization has developed to a certain level, we can create a celestial body that wraps the entire star to collect energy on it, this artificial celestial body is called the Dyson sphere.

For humans on Earth, this kind of technology is still an unattainable theory, what if it is a higher level of civilization? Civilizations that can already travel interstellar are likely to have mastered this technology, and once the star is completely wrapped in a Dyson sphere, the light of the star is also locked and will not overflow. How can humans discover light through astronomical telescopes?

Without that starfield, there are no stars. How can we observe whether there is a civilization without stars? When we look up at the sky at night, the stars we can see with our naked eyes are stars or nebulae.

Wei Hongjun continued to answer Xiuxiu's doubts, he said: "What you said about creation is not entirely correct, if there is life on a planet and civilization has developed, but this planet is like the moon with only one side rotating towards us, and the other side is wild and lifeless, how can we judge whether there is life on it?" ”

When these words were over, the crowd fell silent.

A small question triggers such a deep discussion that is incomprehensible to those who have never been exposed to this knowledge.

Xiang Nan knew that Professor Wei had already spoken very plainly, and if he said some of the report data and obscure technical terms that he usually researched, the people here would probably be dizzy.

The universe is vast and eternal, and Xiang Nan also believes that there is more than one civilization on our earth, but it has not been discovered for many reasons.

The universe is a dark forest, and every civilization is a hunter with a gun...... We have reason to believe that when life on a certain planet develops to a certain level, the existing civilization will gradually find that it is not the only existence in the universe, and will try its best to protect itself.

Wolves on the steppe will hide themselves behind the grass and rocks before chasing their prey, and rats will burrow and insects will camouflage. These are the instincts of life, the instincts to keep themselves from being eaten and destroyed by more powerful creatures, and the instincts to allow themselves to better hide and disguise themselves so that they can get more food to survive and reproduce.

British physicist Stephen William Hawking has always warned mankind not to look for extraterritorial civilizations, not to send signals to the universe, and not to do anything that exposes the existence of earth's civilization. Human civilization is still in the stage of newborn children, ignorant and ignorant, curious about any novelty, and has to explore and find out, and does not know how to hide and protect itself.

It is foolish for us to present ourselves naked in the universe.

Everyone was attentive to listening to Wei Hongjun's popularization of scientific knowledge, even Han Qiao, a big old man, could listen attentively, and for a moment he was overlooked, and Zhao Wuji, who was kneeling beside him, became even more crazy on his face.

He stood up, made a strange gesture of worship, and rushed towards the sacrificial pit not far in front of him.

When Han Qiao realized that something was wrong and hurriedly turned around, it was already too late.

"Zao Wouji!!" Han Qiao shouted, he threw himself on the ground with one lung, and his hands only had time to touch Zhao Wuji's two toes.

However, such first aid was in vain, and Zhao Wuji had already fallen into the shaft, and a dull sound pierced everyone's nerves.

Everyone gathered around the sacrificial pit on the ground and shouted downward.

"Zhao Wuji, Zhao Wuji!"

Another miss made Han Qiao completely collapse, and he sat on the cold ground, his hands pounding heavily and shouting.

"Han Qiao, it's not your fault." Gao Xiaoxi squatted in front of him to comfort the man who blamed himself.

"Zhao Wuji has fallen into obsession, lost consciousness, and even if he doesn't jump, he will do even crazier things. You can see that he can't look at him for a while. ”

Persuading people didn't have any effect on the parties, Han Qiao blamed himself and didn't say a word. Gao Xiaoxi was very worried about what was going on with him and stayed by his side.

The chamber was dark, and the people who came in did not immediately check the whole situation inside because they were tired, but sat on the ground panting and talking. Wei Hongjun also felt remorseful, he knew very well that there was a sacrificial pit in the center of the chamber, but he didn't expect it to be so deep. His misjudgment did not alert everyone in time, causing Zhao Wuji to fall into the well.

The sacrificial pit was deeper than anything he had ever seen.

Illuminating the pit with a flashlight to the south, it was dark 2 meters away, except for the mottled and rough cave wall.

"Zhao Wuji?" The crowd shouted for a long time, but there was no response.

"Team Xiang, what now?" Yun Tianming and Luo Zhan couldn't think of a good way, none of them knew what the situation was below, so they didn't dare to make a rash decision, so they had to ask Xiangnan, who was still calm and composed.

Xiang Nan was silent for a long time before he said: "We don't know what the situation is in the sacrificial pit, so let's find a way to get a rope to tie the flashlight and hang it down." ”

As soon as his proposal was said, Luo Zhan and Yun Tianming, Zhou Fansheng began to untie the belt on his waist. Yuan Fan, Mu Fanqing, and Gao Xiaoxi were all wearing sweatpants and elastic bands, and they couldn't help, so they helped make temporary ropes.

On the other side, when Han Qiao heard this, he not only pulled out the belt, but also took off the travel cedar on his body.

"Xiang team, this clothes, use my clothes." He said as he tore his clothes into thin strips. Han Qiao was the first, and after him, Zhou Fansheng also began to undress.

Soon, an improvised rope was ready, with a south-facing reach, 175 cm and a rope roughly 21 meters long.

Securely tied the torch to one end of the rope, they began to slowly lower the rope.

"Xiang, the light of the flashlight is not enough." The rope is lowered to a height of about 6 or 7 meters and then disappears into darkness, and after about 1 meter down, it is completely invisible to the surrounding situation.

"It doesn't matter, if the flashlight touches the ground, the tension on the rope will be slowed down."

The crowd nervously waited for the signal that the rope would reach the bottom, and just as Xiang Nan lowered the rope to the tail with two lengths left, the taut rope in his hand fell with a loose force.

"The flashlight has hit the bottom."

"Zhao Wuji, Zhao Wuji! You hear me? ”

"Pull the rope while you're still alive."

Everyone waited with bated breath for 1 minute, but the rope did not move at all.

Gao Xiaoxi shook his head and said, "If you fall from such a height, even if you don't fall into pieces, you will go into shock and coma due to severe pain and excessive blood loss." ”

A sentence from the forensic doctor gave Zhao Wuji the death penalty for betrayal.

"No, I'm going to go down and have a look."

"I'm going down too."

Zhou Fansheng and Luo Zhan spoke out one after another.

"No, this sacrificial pit is too high, and if you want to go down, you have to prepare professional equipment. You have to have an outdoor rappelling rope. Xiang Nan understood why the two were in a hurry, they were worried that An Nian and Bai Xiaozhou, who had disappeared, were also below.

Han Qiao exclaimed, "There is a rope on the cruise ship. ”

Both the Shore and the White Birch are docked at the side of the vice island, and both cruise ships are stocked with first aid items such as ropes.

"The problem is that we are trapped on the main island and can't go to the secondary island."

The picture of Fan Ze's death is still vivid, and the passion that everyone has just been aroused is half cooled down.

"The drop box, there must be relief supplies in the drop box." Yun Tianming shouted excitedly, the airdrop box is still hanging on the stone pillar in the sea, even if there is no rope in the box, the rope on the parachute should be enough.

"I'm going to pick up the airdrop." Han Qiao did not hesitate to fight.

The airdrop can't be taken, the storm doesn't know how long it will last, and the people on the island have no food to eat, but the reef under the cliff is a big problem.

Xiang Nan said in a deep voice: "The airdrop is indeed going to be taken, but we have to wait until dawn when the wind and waves are a little lighter, Han Qiao, are you sure you want to take this risk?" ”

Han Qiao said firmly: "Team Xiang, I want to go, because my mistake not only caused my companion to die in distress, but also caused Zhao Wuji to fall into the well and his life and death are unknown." ”

"And I'm very good at water, I'll go tomorrow at dawn, as long as I am careful, I will not have an accident if I descend slowly along the cliff."
