The final location was of course the center of the interior of this huge cigar-shaped mothership. At the same time, due to the order given by Chief Wedel. The tractor beam of the huge cigar-shaped space carrier trying to capture Zhang Desen's spacecraft was also turned off. Zhang Desen, who got rid of the shackles of the tractor beam, immediately drove his spaceship and flew rapidly towards the sea.
While flying, Zhang Desen also used the communicator to shout to Li Longfang at the tail gun position:
"Li Longfang, Li Longfang. Put on your goggles immediately, it's going to explode, hurry up!!!"
Li Longfang immediately replied:
"Captain, please don't worry, I have made all preparations. Don't worry about me, captain."
After hearing this, Zhang Desen immediately replied:
"here you go!!!"
Fortunately, the length of this huge cigar-shaped alien space carrier reaches 5 kilometers. Therefore, it will take some time for a nuclear bomb to fly into the mothership from the front and reach its middle position. This period of time was enough for Zhang Desen to drive his spaceship and escape into the sea.
At the same time, inside the huge cigar-shaped space carrier, his temporary commander, Chief Wedel, took his deputies and guards and escaped as quickly as possible into the specialized cabin next to the main control cab. In the escape spacecraft prepared for the top officer on the spacecraft, he started the spacecraft as quickly as possible and broke away from the huge cigar-shaped mothership and flew into space.
Of course, when he just left the huge cigar-shaped space carrier, he unexpectedly saw Zhang Desen's spacecraft sinking into the bottom of the sea and hiding. This made him even more convinced that Zhang Desen belonged to a higher intelligent civilization on the bottom of the earth. But he couldn't care too much and could only quickly drive his rescue capsule to escape the scene.
But what he didn't notice was that before entering the seabed to hide, Zhang Desen released a small drone from his spacecraft to film what happened at the nuclear explosion site, while Zhang Desen drove the spacecraft to a distance from the bottom of the ocean. , after confirming that everything was safe, began to watch the situation at the explosion site through the previously released drone.
And it was at this time that the two nuclear bombs, each with a yield of 50,000 tons, finally exploded. Suddenly two huge mushroom clouds appeared in the sky. And because it exploded inside that huge cigar-shaped space carrier, the entire space carrier was blown to pieces.
Moreover, the huge nuclear explosion shock wave quickly swept through everything around him along with the huge flash that had appeared. Soon, not only the huge cigar-shaped space carrier was completely destroyed, but Wedel's life-saving spacecraft was also affected. Although he was trying hard to fly into space, his speed could not exceed the shock wave, so his spacecraft also It caused violent vibrations.
At the same time, the huge shock wave quickly affected the drone Zhang Desen had left over the ocean. The drone quickly reduced to powdery debris. At this time, Zhang Deshengsen, who was watching the results captured by the drone on the screen on the seabed, soon saw that the signal was lost on the screen.
At this time, Zhang Desen, who parked his spaceship in a large coral patch on the seabed, saw the signal loss prompt on the screen, and used the communicator to say to Li Longfang, who had faked the position:
"Hey, Brother Long Fang, we are really lucky! If our spaceship hadn't flown fast enough and reached such a far and deep seabed all at once, I'm not sure we could have escaped this time. The big explosion. I don’t even know if this radiation will also cause harm to us!”
Li Longfang said:
"I feel a little strange that he was able to withstand the impact of those small meteoroids before. How come it was so easily shattered by nuclear weapons this time?"
Zhang Desen replied:
"Why did you forget that nuclear weapons were used this time? And they exploded inside his spaceship."
After hearing this, Li Longfang said apologetically:
"I'm sorry, captain. I seem to have asked a confused question. I was shocked by the thrill just now. I'm sorry. My captain."
Zhang Desen replied:
"Ah, anyway, this operation is indeed a bit risky. But based on the data returned by the drone just now, it seems that there is part of the huge cigar-shaped space carrier.
The alien in the trap escaped in a smaller rescue capsule. Since the drone was also damaged by the shock wave, I have no way of knowing whether the shock wave of the nuclear bomb also impacted them. "
After hearing this, Li Longfang replied:
"I think Captain doesn't have to worry too much. If they escape, we can just settle the score with them after we get to Mars."
After hearing this, Zhang Desen immediately replied:
"But judging from the situation now, we may have to wait a while before we can leave. I want to check the surrounding radiation levels to confirm how far we have to fly out of the sea. Although there is no radiation around Alerts are on, but it’s better to err on the side of caution.”
After hearing this, Li Longfang said:
"By the way, Captain. Judging from the images returned by the drone this time, this double mushroom cloud is really similar to the double mushroom cloud in the Ulangumu area! If we didn't know it in advance, we wouldn't be able to tell it at all. It’s a double mushroom cloud.”
And Zhang Desen said:
"Okay, the two nuclear bombs exploded so close together, it must be
There will be such strange phenomena. The two mushroom clouds are almost embedded together, which will definitely create a lot of illusions. Anyway, as long as our mission is completed, there is no need to worry about others arguing about how many mushroom clouds there are. "
After hearing this, Li Longfang suddenly asked:
"Captain, judging from the current situation, it should be dawn already. Is there something wrong with our watches? We still can't feel the dawn."
Zhang Desen replied:
"It's already bright. There's no mistake. It's just that the sea bottom we're at is a little deep now. However, if the sky gets a little brighter, you can still see the sun here. It's just that it's still very dim. You'd better wait for a while. "
After hearing this, Li Longfang had no choice but to say:
"Hey, I didn't expect it to be so hard to see sunlight at the bottom of the sea. In the past, when I heard what the captain said, I couldn't imagine it. But captain, what is the current scene on the sea level? We Do you want to send another drone over the water?”
And Zhang Desen said:
"It's no longer necessary. Although our drones can also dive properly and fly out in the water. But we don't need to lose so many drones in vain now. The data collected by the previous drone is enough. And don’t forget that we have to go to Japan’s Mount Fuji later to see if it is an extinct volcano or an active volcano. And I also want to see how it is different from the same mountain in my universe.”
Similarly, Li Longfang still has questions about the specific differences between extinct volcanoes and volcanoes. So he once again hoped that Zhang Desen could explain it to him. Zhang Desen also immediately briefly explained some relevant information to him. The approximate content of this information is:
Volcanoes are a common landform, mountains formed by the accumulation of underground molten materials and the solid debris they carry after they rush out of the surface. There is a "liquid zone" 100 to 150 kilometers below the earth's crust, in which molten silicate material containing gaseous volatile components exists under high temperature and high pressure, that is, magma.
Once it breaks out of a weak spot in the earth's crust, it forms a volcano. Volcanoes are divided into "active volcanoes", "extinct volcanoes" and "dormant volcanoes". Volcanoes are windows to the hot core of the earth. They are the most explosive force on the earth. When erupting, they can eject a variety of substances. The main substance is volcanic ash. The volcanic ash solidifies into volcanic mud. Volcanic mud is used in the fields of metallurgy, chemical industry, medical treatment, and wall materials. Wide range of applications. Hazards include: volcanic debris flows, lava flows, etc.
Among them, extinct volcanoes refer to volcanoes that have erupted in prehistoric times, but have never been active or erupted for a long time in human history. This type of volcano has lost its ability to move because it has not erupted for a long time.
Some volcanoes still maintain their complete volcanic form, while others have been weathered and eroded, leaving only incomplete volcanic remains. Mount Kilimanjaro in eastern Africa and the Datong Volcanic Group in Shanxi, China are all extinct volcanoes. Among them, the Shanxi Datong Volcanic Group has two isolated volcanic cones distributed within a radius of about 50 square kilometers. Among them, the Langwoshan Volcanic Cone Nearly 120 meters high.
How did the extinct volcano form? Scientists believe that the energy driving the activity of the extinct volcano is buried 65 kilometers to 80 kilometers underground. The deepest drilling in the world today is 8
It was built by the Soviet Union in the 1900s and is 12 kilometers deep.
It is not yet possible for scientists to place experimental instruments at ideal depths to detect the source of extinct volcanoes.
Today, the main methods for studying extinct volcanoes include: using orbiting satellites, computers and highly sophisticated instruments to observe, collect and analyze various data on extinct volcanoes; analyzing the rocks and materials of extinct volcanoes in the laboratory or conducting simulation experiments to Speculate the mechanism of volcanic eruptions.
An active volcano is one that erupts and is expected to erupt again. Dormant volcanoes, even those that are active but are not about to erupt, are also called active volcanoes that may erupt again.
Volcanoes that last erupted a long time ago and are proven to be unlikely to erupt in the foreseeable future are called extinct or extinct volcanoes. Generally speaking, only active volcanoes erupt. Volcanoes that have the ability to be active (erupt) regularly or periodically during human history.
Active volcanoes in the world are still erupting frequently, such as Mount Etna in Sicily, Kilauea volcano on Hawaii Island, Mount Vesuvius in Italy, Krakatoa in Indonesia, and Mount Krakatoa in Africa. Nyiragongo volcano, etc., are all famous active volcanoes.
The eruptions of active volcanoes are cyclical. For example, Mount Merapi on Java Island has been erupting continuously for an average interval of two or three years since this century. The eruptions of active volcanoes are also intermittent, but the length of the intermittent periods varies.
The formation of volcanoes involves a series of physical and chemical processes. The crust and upper mantle rocks are partially melted and separated from the parent rock under certain temperature and pressure conditions. The melt migrates upward through pores or fissures, and is gradually enriched in a certain location to form a magma pocket.
As magma continues to replenish the magma sac, the magma excess pressure gradually increases. When the surface covering is not strong enough to prevent the magma from continuing to move upward, the magma rises toward the surface through weak zones.
During the ascent, the volatile components dissolved in the magma gradually dissolve to form bubbles. When the volume fraction occupied by the bubbles exceeds 75%, the bubbles trapped in the liquid will be quickly released, causing the magma viscosity to drop to a very low level after the explosive eruption gas is released. , the flow transforms into turbulent nature. If the magma has low viscosity or low volatile content, there will be only quiet overflow.
Different forms of a series of physical and chemical processes from partial melting to eruption
Formed various volcanic activities.
A dormant volcano refers to one that has erupted in history. But the volcano has been relatively static for a long time. Such volcanoes have well-preserved volcanic forms and are still capable of volcanic activity, or it cannot be concluded that they have lost their volcanic activity.
For example, Tianchi in Changbai Mountain in China erupted three times in 1597, 1668 and 1702, and there were many activities before that. Although there is currently no eruptive activity, high-temperature gases are continuously ejected from some unfathomable fumaroles on the slopes, indicating that the volcano is in a dormant state.
There are 516 active volcanoes in the world, 69 of which are volcanoes at the bottom of the ocean, with the largest number in the Pacific. Active volcanoes are mainly distributed in the Pacific Ring of Fire, the Mediterranean-Himalayan-Indonesian volcanic belt, the mid-ocean ridge volcanic belt and the Red Sea-East African continental rift zone.
There are about 900 Cenozoic volcanic cones in China, with the largest number in Northeast China and Inner Mongolia, about 600 to 700. The volcano currently erupting is the Karda volcano in Yutian County, Xinjiang. The distribution of volcanoes is controlled by global plate tectonics.
Such as the Shiveluch volcano on the Kamchatka Peninsula in Russia. On the morning of April 17, 2012, the Hivelucci volcano erupted violently, emitting volcanic ash 9,500 meters above sea level. The report said that professionals from the Far Eastern Institute of Volcanology and Seismology of the Russian Academy of Sciences observed the erupted volcanic ash at a research station 40 kilometers away from the volcano. The volcanic ash flow stretches for 100 kilometers in the east direction.
The eruption was the most powerful eruption of the volcano since early 2012. Although the volcanic ash will not have a serious impact on nearby residential areas, it poses a threat to local aviation safety.
Volcanic activity is a cosmic natural phenomenon. Aerospace exploration has discovered that there are volcanic activities on the moon, Mars, Venus, and Io.
After Zhang Desen roughly said these contents, he said to Li Longfang:
"Brother Long Fang, now I am going to start detecting the surrounding radiation and other data. Now you can just be quiet."
We will be on guard at the rear and leave the rest to me. "
After hearing this, Li Longfang immediately replied:
"Don't worry, Captain, I will be very vigilant about everything behind you."
Then, Zhang Desen and Li Longfang immediately started doing their own things.
And of course, at this time, over the sea, the huge cigar-shaped alien space carrier had been reduced to ashes. Its wreckage began to be scattered around the island. Even after the giant cigar-shaped alien space carrier was wiped out, the wandering aliens still inside disappeared with its destruction.
The huge explosion also caused shock to some advanced intelligent civilizations. Among them, the monitoring instruments on the Gomar space carrier "Serpent" visited by the West Atlantis Empire immediately received this amazing explosion vibration data.
Likewise, both the West Atlantis Empire and the East Atlantis Empire quickly monitored this data. They had to say that they were all shocked. They even began to dispatch their respective military forces in unison to detect what was going on in this area.
As for the Dinosaur Orme Empire and the Terrifying Galaxy Empire, all the eyes were suddenly attracted to the waters around Bikini Island.
They also began to prepare for war with other unknown advanced intelligent civilizations at any time, and began to send out their own detection and military forces. Use your own military power to protect your own detection capabilities to ensure safe and smooth detection.
Suddenly, the Bikini Atoll became the focus of all forces. Of course, Zhang Desen had not thought of this issue before. However, after he checked the radiation data around him and began to confirm that everything around him was safe, he originally wanted to start returning slowly according to his original plan.
When you reach the sea area suitable for flying out of the water, then fly out of the water, and everything will be safe. And while it's safe, take a trip to Mount Fuji in Japan to see whether it is an extinct volcano or an active volcano.
But just when he was about to notify Li Longfang, he suddenly thought of it. Such violent explosions before would definitely attract the attention of various high-tech civilizations. Only then did he feel that he was a little careless and forgot to be alert, and other possible threats would suddenly approach.
However, after he thought about it carefully, he believed that those more threatening advanced intelligent civilizations would not arrive as soon as possible, because he felt that they must also be worried about other advanced intelligent civilizations. Therefore, those advanced intelligent civilizations must make a lot of preparations before coming.
These preparations are made to protect the safety of their own detection personnel, so they must still need some time to prepare before they can come over. But this also proved that she didn't have much time. After Zhang Desen came up with the plan, she suddenly decided that she might need to make a big circle to the east to ensure the safety of her return.
But after he thought about it carefully for a while, he rejected the plan. Because the direction of the West Atlantis Empire is exactly to the east at this time. If you head east at this time, you may accidentally bump into the approaching exploration and military forces of the West Atlantis Empire.
So Zhang Desen thought for a while and decided that it would be best to take a detour to the west. After thinking about it carefully, he still didn't want to give up his decision to explore Mount Fuji in Japan. At this time, he decided to discuss it with Li Longfang and decided to start asking questions.
