Deep in the oceans, about four billion years ago, high-energy chemical reactions created self-replicating molecules. Five hundred million years later, the common ancestor of life appeared and differentiated into bacteria and archaea. Early algae plants grew under the ocean and drifted with the sea water. Early life forms developed the ability to photosynthesize, using solar energy to release oxygen into the atmosphere. The oxygen accumulated in the atmosphere is affected by ultraviolet rays emitted by the sun, and the ozone layer appears. Early life should have been in the ocean. During the evolution of life, some small cells were synthesized or annexed to form large cells, thus forming eukaryotic cells with relatively complex structures. The cells in each part of the cell community gradually differentiate into different functions, forming multicellular organisms.
In the depths of the ocean, it is difficult for sunlight to shine in, so it looks particularly dark. In the dark depths of the ocean, we can see many transparent fish, which are very beautiful, swimming among the algae and preying on some mayflies. The ocean is still calm at this time. In the dark deep sea, there are many volcanoes and earthquakes, and the bottom of the sea is still hot. The seawater rolls and boils, the seafloor plates move violently, triggering volcanic eruptions, magma erupts like a fountain, thick smoke rises straight to the sea surface, seawater rolls, and seafloor faults move violently, colliding, squeezing, and bulging with each other. A major earthquake caused the seawater to flow back and the continent surfaced. This may be the original continent or island.
The big waves are like rolling up thousands of piles of snow, and the waves are rolling and rolling on the shore. As the water recedes, some fish wash up on the shore. Most of the fish that were not adapted to life on the mainland have died, and those that have adapted have evolved to have legs that are easier for running and crawling to live on the mainland. Vegetation grew due to photosynthesis. Most of the land was covered by vegetation, and the earth had its own color. At this time, trilobites began to appear. There are anomalocariids in the ocean, evolving from invertebrates to vertebrates. The vegetation is also more luxuriant. On the vast land, there are endless mountain peaks, layer upon layer of mountains, and green trees, which are filled with smoke, as if entering a dream. Most of the plants at this time were ferns. Among the lush weeds, trilobites crawled out. The trilobites gathered together in clusters or stood in rows in the open space. It's sunny today, such nice weather. The gathering of these trilobite tribes seems to be holding a morning meeting. Standing in front of them may be the leader of the trilobites. Trilobites are the most representative ancient creatures from the Cambrian period 560 million years ago. They are a type of arthropod, and their whole body is clearly divided into three parts: head, body and tail. The carapace is hard, and the carapace is divided longitudinally into three roughly equal pieces by two dorsal grooves, one rachis lobe and two costal lobes, hence the name trilobite. Trilobites coexist with corals, crinoids, brachiopods, and cephalopods. Most of them live on the bottom of shallow seas before they can crawl, semi-swim, or live in mud. Apparently these trilobites were washed onto land by the tides.
The leader of the trilobites stood up and faced everyone: "Look at this vast land, where should we hunt for food?" A trilobite in the queue replied: "Let's forage separately." The leader After hearing this, he agreed and began to divide the work and arrange tasks. Each group was led by a trilobite, divided into three groups, and dispersed. At that time, our earth was basically surrounded by oceans. When the sun goes down, they gather in their original place and return to the nearby shallow sea.
There are various life forms in the shallow sea, including anomalocaris and sea crabs that are several meters long. They were the overlords of the ocean at that time and ruled the entire ocean. Anomalocaris, also known as Anomalocaris, has a pair of large claws in front of its head, eyes as big as ping pong balls, a pair of giant segmented forelimbs for quickly catching prey, a beautiful large tail fan and a pair of long tails cross. Although it is not good at walking, it can swim very quickly. The huge mouth with a diameter of 25 centimeters can prey on any large creature. There are also external teeth arranged in a ring, which poses a serious threat to those animals that have evolved outer armor for protection.
The trilobite group returned to the shallow sea bottom and crawled slowly, swimming freely. Perhaps they were discussing the results they had harvested today. This time the tide washed them to the only piece of land, which they discovered. Trilobites are good at crawling, and land may be more suitable for their lives. At this time, they are discussing how to return to land. Returning to land is their biggest wish. In the shallow sea, there are also weird-looking marr bugs and single-walled snails, as well as Otto bugs, worms, and grotesque bugs that are good at drilling into the soil. The grotesque bug is a worm-like animal that is about 5.5 centimeters long. Its entire body is tubular, with up to ten pairs of slender legs, and seven pairs of spikes on its back. It is good at protecting itself from being hunted. There are also plant-like stomach-crawling worms with armor and long spines on their backs, and the slug-like Weiwasi. A wide variety of creatures make this area of the ocean teeming with life. Algae plants grow in clusters, which are even more colorful and dazzling.
Stomach-crawling worms and Wewassian worms are good at hiding. The trilobite faced them and said: "You are good at hiding, and you are responsible for observing the enemy's situation. If there is any enemy situation, report it to me immediately." The stomach crawler and the wewassian were separated in the four directions of southeast, northwest, and they were hidden under a plant. They might lie down on the algae plants and extend their spikes for defense, or hide in the sand and rocks to peek. In the depths of the ocean, several behemoths - Anomalocaris and Wewassian worms - climbed onto the algae. They moved briskly and came to the leader of the trilobites and said hurriedly: "First..., leader, there is an enemy ahead. The leader of the trilobites stepped forward and asked: "Can you see clearly what it is?" The Vespa replied: "Yes, it's Anomalocaris, about twenty or thirty of them." They heard that it was Anomalocaris. , fleeing everywhere, some hiding in the sand and rocks, some hiding under the seaweed, and some hiding in the cracks of the rocks. Only the trilobites move the slowest. The anomalocaridids were lingering in the sky, and suddenly they swooped down, causing dust to fly. Their strong forelimbs grabbed the trilobites and stuffed them into their mouths, biting off the trilobites and spraying out the plasma. Just when they were enjoying their capture, the sea crabs hiding in the dark suddenly came to attack the anomalocaris and wanted to dominate the ocean. The sea crab was as big as a large crocodile. It was the number one killer in the ocean at that time. The huge pincers in front of it could cut large fish into eight pieces. The most cruel thing was the fight between the same kind, and even the relatives refused to recognize each other. A group of sea crabs hid behind boulders and suddenly launched a sneak attack on the anomalocaridids, disrupting their formation and fighting each other. Severed limbs floated over the ocean, and some fell. The strange shrimp swooped down, hit the sand and rocks, and picked up the broken limbs with its front pincers and put them into its mouth. As the saying goes, if two tigers fight, one of them will be injured. In this battle, the strange shrimp was severely injured, and twenty or thirty of them were The number of strange shrimps suddenly dropped by half, and these strange shrimps had no choice but to flee when they saw the situation. The sea crabs also suffered a lot of losses, so they left in despair to recuperate.
A large number of their kind died in the mouths of the Anomalocaris. They were helpless and helpless as they watched the Anomalocaris eating their own kind. They were very sad, and some even cried sadly. A trilobite stood up and reprimanded: "Why are you crying? We must unite to defeat the anomalocaridids and sea crabs." The Wewasi worm stood up with some doubts and asked: "They are so powerful, we How can we defeat them?" This trilobite also had no idea. It asked the other trilobites, "What can you do?" Everyone shook their heads and said, "We don't have anything to do either." The trilobite meditated for a long time, looked at its leader, then faced everyone, and said: "Although they are very powerful, they are not terrible. We need to find someone more powerful than them to fight against the anomalies and sea crabs." "The stomach crawler stood on the spot and said: "I just heard that there is a swimming dragon in the east. It is shaped like a snake and is tens of meters long. It is much bigger than anomalocaridids and sea crabs." Trilobites Urgently asked: "Where can we find the wandering dragon?" The Stomach Crawler said: "I only heard about it. I heard an elder say that we don't know the specific place. I heard that it is in a distant place. The East China Sea is far away from our South China Sea." After hearing this, Trilobite was anxious to see the elder and said: "I want to see the elder you mentioned."
The stomach crawler and the trilobite stood under the tall rocks, where various fishes were swimming. The stomach crawler took it into a deep cave. In the cave lived a huge stomach crawler, with a huge meat ball underneath. Only when you looked up could you see its head. It seems that this huge stomach crawler has grown together with the rocks, making it unable to move. The old stomach crawler may have lived in the cave for tens of thousands of years. The hoarse voice said: "What kind of insect is here?" The trilobite bowed down and looked up at it, saying: "I am from the trilobite clan. I am here to inquire about the location of the wandering dragon. Please let the elders tell Yu Wansheng." The old stomach reptile said: "The journey here is long, and with the difficulties and obstacles, life may be in danger. Aren't you afraid?" The trilobite said with a very firm will: "As long as we can defeat the anomalies, With sea crabs, all difficulties are no longer difficulties." Seeing its courage, the old stomach crawler said: "Young insects are young insects, full of vitality, perseverance and fighting spirit. I have already lived here. It has been more than 30,000 years, and you no longer have that fighting spirit. Very good, you are a vigorous insect." The trilobite looked up at the old stomach crawler and said: "Elder, please tell me where the dragon is?" Seeing that it was so persistent, the old stomach crawler said: "Okay, okay, I'll tell you. The wandering dragon lives in the far east, where the sun rises. You can always go east, where the sun rises." There is a place called Longxu Great Trench, where there are many large volcanoes, and the sea water is like boiling water. There is a deep pool of magma, and the deep pool of magma is filled with hot magma. No living thing can get close to it. If you get close to this deep pool of magma, you will be sucked into the magma by strong gravity, and there will be no bones left. You have to think about it." Trilobite said: "Elder Xie can tell Yu Wansheng that Wansheng has already thought about it. , I must go to this place as a youngster, and sacrificing me as a bug to save the tribe is insignificant." After hearing this, the old stomach crawler was happy, what a young boy, and really wanted to like it for this sentence, and said: "Okay What a murderer! Young man, go ahead, I will pray for you and wish you a safe return."
