The insects looked up at the wandering dragon, worshiped and shouted: "God! God! God!" Leader Zhang Huai faced Trilobite and said: "Sanye, you have been away for three years. The leader has been looking forward to your return. A vertical line will be drawn on the ground every other day, but it is a pity that it still has not waited for your return." The trilobite asked urgently: "What's wrong with it first?" Leader Zhang Huai couldn't hide the pain in his heart, choked with sobs for a while, and said: "A year after you left, the strange shrimps came out to attack our Zerg tribe. The first leader was forced to fight and unfortunately died in the battle. The Zerg tribe suffered the greatest purge in history. Coupled with volcanic eruptions and frequent earthquakes, the Zerg tribe fell from a million to a million. It can be reduced to 30,000. This is a major disaster in the history of our Zerg race." Hearing this, the trilobite felt extremely sad and could not express its feelings in words at this time. Leader Zhang Huai said: "The former leader had his last words when he was dying. The former leader said that you were strong-willed, wise and courageous. After the death of the first leader, I was chosen to take over the position of leader temporarily. When you come back, I will relinquish the position of leader to you." Three. When Ye Chong heard that leader Zhang Huai wanted to give up the leadership position to him, he postponed it many times and said: "I will obey you as the leader. You have not done anything unethical during your tenure as leader, and you are highly respected. I will be the leader." I am not very talented and may not be able to hold a big position." Leader Zhang Huai said: "This is the last wish of the former leader. Aren't you still going to obey it?" Trilobites could not go against the last wish of the former leader, so they had to agree and choose a good time. On an auspicious day, a coronation ceremony will be held.
Trilobite climbed to the position of leader step by step and sat down facing everyone. The insects knelt down and bowed three times and kowtowed, and shouted: "My lord, for thousands of years, I will shine with the sun and the moon, creating thousands of generations." The trilobite took the position of leader, and from then on it was the master of all the insects. The trilobites stood up and said, "Your Majesty, please stand up." The insects stood up and looked at the leader. Trilobite said: "The anomalies and sea scorpions are the overlords of the sea. If they are not eliminated, hidden dangers will always threaten our Zerg race. Please discuss this carefully." Youlong stood behind them with a cold look. , said coldly: "It is very simple to get rid of these two evils. The troops are divided into two groups and take the initiative to attack, attacking the sea scorpions along the way and the anomalocaridids all the way. All you need to do is to lure them out without losing. Finally, the leader will lead a group of Only elites destroyed their nests and cut off their escape route." After a major volcanic eruption and earthquake, the strength of Anomalocaris and Sea Scorpions was greatly reduced, from millions to dozens, but they still cannot be underestimated. watch for. Although their strength is greatly reduced, they are still the overlords in the ocean, because the skinny camels are bigger than horses.
This is a life-or-death battle. The Zerg soldiers attack in two groups and lure out the Anomaly shrimp and Sea Scorpion. The Zerg formed battle formations and prepared to fight. Unexpectedly, these battle formations broke up and began to withdraw their troops. Perhaps the anomalocaridids and sea scorpions are too ferocious, and they chase these bugs fiercely, and many bugs become their food. Let them taste the sweetness first. Anomalocaris and sea scorpions hunted everywhere, and this time they came out in full force, giving the enemy an opportunity to take advantage of them when the anomalies and sea scorpions were chasing them far away. The leader Trilobite led an elite force to occupy their nests and destroy them, cutting off their escape route. When the anomalocaridids and sea scorpions were enjoying their prey, a huge swimming dragon appeared in front of them, blocking their way. The swimming dragon is much larger than them. It roars in the air, hovers above, rushes down and knocks over the anomalocaridids, fights with them, and presses and rubs the sea scorpions with its front paws. Anomalocaris and sea scorpion don’t know what this is? They were so powerful that their size was enough to crush them, leaving them unable to fight back. In this battle, there were only a dozen sea scorpions and anomalies in total, and they fled away when they saw the situation. The swimming dragon hovered in the sky, a mouthful of magma spewed out, and the hot magma sprayed down. The sea scorpions and anomalocaridids were almost extinct and had no ability to compete with it.
After the battle, Youlong was about to leave. The leader Trilobite rushed forward and said: "Youlong." Youlong looked back and said, "You can do it for yourself." Youlong rose into the air and swam away. No one knows where it goes after that? It is said that it returned to the East China Sea and lived in the deep pool of magma, and it has never been seen. It is like evaporating among insects. There is also a saying that after the first mass extinction, it also disappeared with it. Later generations of trilobites went to the East China Sea many times to search, but no trace of the swimming dragon was found. The trilobites no longer had the threats of sea scorpions and anomalocaridids, and lived a quiet life. Trilobites reproduce very quickly, multiplying by the millions, and the insects flourish, creating a scene of prosperity, breaking the balance of the marine life chain and becoming the last overlord.
At the end of the Cambrian period, horseshoe crabs appeared. Horseshoe crab, a marine arthropod of the order Stegopleura, looks like a crab with a greenish-brown or dark brown body. It has a hard carapace and four eyes, two of which are compound eyes. There are two small eyes of 0.5 mm on the front of the head and chest. , sensitive to ultraviolet rays, only used to perceive brightness. There is a pair of large compound eyes on both sides of the head and breastplate. Although horseshoe crabs can flap their gills with their backs downward to propel their body swimming, they usually bend their bodies into an arch shape, burrow into the soil, and then push their bodies forward with their sword tail and last pair of legs. This may be the number of horseshoe crabs. Let’s avoid the mass extinction of life for the first time.
At this time, the sky was covered with dark clouds, and the layers of dark clouds were low. The meteors dragged their long tails through the thick clouds and scattered on the sea surface. Little sparks spread, rolling up layers of heat waves and beating down. Suddenly the entire ocean turned into a sea of fire, the surface temperature suddenly increased, and the sea water was like boiling water, with steam rising up. Large and small volcanoes on the seafloor began to erupt frequently, magma erupted, and the entire ocean turned into a magma sea and began to solidify. Layers of heat waves break through the solidified ocean. There was lightning and thunder in the sky, and the lightning broke through the thick clouds and spread in the dark sky. The charged clouds illuminated the entire dark sky, and a bolt of lightning broke through the thick clouds like a beam of light and hit the bottom of the sea. Burnt carcasses of animals can be seen everywhere on the seabed. The huge thunder resounded throughout the sky, deafening, and caused the entire ocean to tremble. The strong earthquake caused obvious changes in the ocean. Such a shock was felt all over the world, as if the earth was turned upside down. The rock formations on the sea floor began to be torn apart, impacting the folds and rising high, forming continents. The major plates were lifted up by strong impacts, forming tall mountains. This continent occupies 30% of the surface area, and 70% is ocean. This time is different from previous land-building movements. Some places began to sink and become a vast ocean, and some places began to rise and become highlands, forming various mountain ranges, with high in the middle and low on all sides. In the middle of the continent is a mountainous area, surrounded by plains and basins. There are undulating mountains around it, stretching for dozens of miles. Some tower into the sky, with rolling clouds and mist filling the entire mountain peak, and there are also sheer cliffs. Earthquakes, large and small, last for hundreds of thousands of years and are so large that they can be said to affect the entire world.
Two primitive continents were formed, Laurasia and Gondwana. The two continents merged into one ancient continent, which was high in the middle and low on the four sides. Rivers and lakes were formed by rainwater, and big rivers flowed into the sea.
The weather was changing, the clouds were rolling and the clouds were relaxing. After hundreds of thousands of years, the surface temperature began to drop, falling rapidly to more than 40 degrees below zero. After a few days and nights, the sun sets and the moon rises, heavy snow begins to fall in the sky, rivers and lakes begin to freeze, and the world enters an ice age. It was a vast expanse of white, and the snow on the high mountains was getting thicker and thicker, forming snow peaks. Glaciers froze the entire earth, and ice winds blew. At dawn the next day, the sun rose in the east and illuminated the entire earth. The earth began to gain warmth, and the day began.
The earth began to melt, the ice strips turned into water droplets, and life on the seabed revived again. That is, from 480 million to 440 million years ago, primitive vertebrates began to appear and entered the Ordovician period. The glaciers on the continent began to melt, the temperature rose, and ferns began to grow, spreading around the world, and at the same time suffered widespread sea invasion. This era was an era of relatively intense volcanic and crustal movements, with divergent climates. It was also an era of glacial development, when marine invertebrates truly reached their peak. This was also a period of obvious ecological differentiation of biological processes. There are vertebrates on land such as freshwater jawless fish, star turtles, frilled fish, etc. Algae plants are also beginning to grow, the nautilus in the ocean, which is a carnivore in the ocean. Trilobites at this stage have many needles growing on their chest and tail. In the late Ordovician period, important structural changes occurred in many areas of various continents. Magmatic activity and thermal metamorphism caused some active areas to fold into mountain systems, which changed the contours of the crustal structure and paleogeography to a certain extent.
449 million years ago, in the universe 6,000 light-years away, nebulae expanded and dispersed, rotating at an hourly speed, with a loud noise, a huge star collapsed and condensed into a point of light, exploded and spread, bright light Ejected, this is the terrifying gamma ray. It shot at extremely high speeds in the vast universe, passed through the atmosphere, hit the earth, shattered the gas molecules, and the atmosphere suddenly fell apart, and the earth shook violently. The halo spread smoothly, and the dust rolled up was like a storm. The mountains and rivers were instantly flattened, and the vegetation was uprooted and torn into pieces. A year later, famine spread across the world, and similar species killed each other and competed for prey; decades later, the broken gas molecules regrouped to form the toxic gas of nitrogen dioxide. Nitrogen dioxide blocks the sky and the sun, making the sky dark and the ground dark, and the temperature drops. The climate at this time was extremely unstable. Huge waves stirred up the sea water, making it turbid. The first thing that caused the nautilus to become extinct was the extinction of the nautilus. Five hundred years later, the seawater began to freeze, and the animals in the ocean lost their habitat. The spread of glaciers consumes large amounts of sea water, and sea levels drop to form land and islands. One hundred and fifty thousand years later, animals became extinct in the severe cold, and all living things on the earth almost disappeared. There was silence and darkness again, and there was an aura of death. At this time, the earth will need to wait one hundred thousand years before it can regain its former vitality.
