The ecosphere of the Ark of Earth has a mysterious realm, where legend has it that there is a lake called "Heart Lake", which can only be reached by the dead, where the mother of mankind "Liujin" and the father of mankind "Harumi" sleep, but no living person can walk into it and then walk out of it safely. Looking down from above, it was foggy, and when the plane flew into the clouds with extremely low visibility, it was impossible to distinguish between the southeast and the northwest, and even the radar was out of order, and there was no place to land. If you try to enter this mysterious area by land, you must pass through the outer forests and swamps, but no matter how you go in that direction, you will eventually turn back, go around and around, and walk in the same place, and you will not be able to enter the legendary mysterious heart lake. In the limited cognition of human beings, only through a bamboo forest town can we reach the shore of the heart lake, and the families who live in seclusion in the depths of the bamboo forest village are said to be the descendants of angels, guarding this only road to the heart lake for generations. But the people who live in seclusion in the land of the bamboo forest will not easily go out of the land of the bamboo forest, but when the "Silver Moon" of the Earth Ark Zhi Brain asks them to take the "Yuan Shui", they will send their clansmen to the edge of the Bamboo Forest Township to receive the hollow storage container at the agreed place, and then they will go to the heart lake to draw "Yuan Shui", and store the "Yuan Shui" in the container, and then send it back to the agreed place, and the Zhi Brain "Silver Moon" will send personnel to take the "Yuan Shui". Legend has it that the mysterious heart lake is the birthplace of "Yuan Shui", and the heart lake is connected to a number of underground rivers, and these rivers are connected to the ocean of the ecosystem, which contains rich spiritual power after being diluted by ordinary river water and seawater, nourishing various life forms in the ecosystem, and flowing into the water circulation system in the human living area, providing human beings with the water resources needed for life. But if you want to enter the mysterious heart lake smoothly from the complicated and complicated underground rivers in all directions, it is almost impossible.

Li Xinjian, who didn't know anything about this heart lake, was talking to his sister telepathically, and he said to Li Xinying: "I found out the clues about the disappearance of my parents from Captain Enron. Captain Enron admits that he called our mom and dad from his home in American City, and he asks them to rush to a place outside Eden as soon as possible the next day to find and pick up a friend of his who has lost contact with him in the wilderness. His friend retired from the Moonback Base and later became an Ecosphere Guardian, but for some reason entered the biosphere without permission and disappeared, saying that he received a call for help from his friend, which was sent from a location close to Eden. So he sent a navigation route to his father, asking his parents to rent a self-driving electric car the next day, and downloaded the navigation route on the electric car, and he would automatically find his friend, and then his parents would pick up his friend and return to Eden City. I hope that my friends can find him before his work unit finds out that he is missing, so that he can return to his post and escape the fate of being punished for his illegal ecosystem."

Li Xinying sighed with emotion: "With my father's affectionate and righteous character, I will not refuse the request of Captain Enron, who has worked with him for many years and was born and died together, and my mother is not worried that my father will go to the ecosystem alone to rescue Captain Enron's friends, so she will walk with her father. So, why did our father and mother disappear?"

Li Xinjian recalled: "When Captain Enron learned that our parents were in the ecosystem to pick up his friend, he sent someone to pick up the leader of the "Ark Pioneers", and even he didn't know where our parents were now, so he directly inquired with the leader of the "Ark Pioneers", and the answer he got was that our parents were safely living in a certain part of the ecosystem, and that location was very hidden and could not be easily accessed. It is worth mentioning that Captain Enron is also a member of the "Ark Pioneers", his identity is known to his father, so Dad really believes in Captain Enron, and has a friend who is also a member of the "Ark Pioneers", because he is engaged in a secret mission and enters the ecosystem without permission and loses contact, and needs his parents to take him back to Eden City. In fact, most of the staff of the moon base are members of the "Ark Pioneers", the reason why the "Ark Pioneers" organization was established is because their leaders discovered the fact that the end of mankind is coming, in order to avoid causing unnecessary panic among the people of the Earth Ark, they silently change the fate of the Earth Ark The end of the Earth Ark is coming, and they are engaged in saving the earth outside the system. Exploring human living space in outer space. They have also repeatedly stated the fact that the end of the Earth Ark is approaching to the Earth Ark, hoping that the Silver Moon will come to their senses and work with them so that the human beings of the Earth Ark can survive the apocalyptic crisis."

Li Xinying asked, "In our home in Huaxia City, my father's fountain pen was searched, and ink containing crown fungus was found in the pen, what is Captain Enron's explanation?"

Li Xinjian replied: "Captain Enron admitted that the old and valuable fountain pen was a gift that my father gave to him as a memorial when he retired and returned to Earth. But he denied that the fountain pen contained a sample of the crown fungus, because he kept it close to him until the day before his father returned to the Ark on Earth, when he found a beautiful box containing the fountain pen and gave it to him himself."

Li Xinying wondered: "It is not impossible to develop a crown fungus that targets trees, to make the crown fungus spread silently in the ecosystem of the Earth Ark, to control the drone, and to launch an attack on the Zerg Zhuoer and our master-apprentices, the leader of the "Ark Pioneers" with great powers, wants to get a false test result and falsely accuse our parents of being the black hand of spreading the crown fungus in the ecosystem, but why did he do it? What is his motivation behind it?"

Li Xinjian said solemnly, "Captain Enron feels very guilty for indirectly causing his parents to disappear, but he has always been silent about who the leader of the "Ark Pioneers" is. After we were hit by artillery fire in the sky over Jupiter in a battle with the Virdons, only one of the survival pods on the small space fighter we piloted was able to move normally, and he gave me the only one that was not damaged. He stayed on the exploding spaceplane, knowing that his chances of survival were slim, and he told me the true identity of the leader of the Ark Pioneers, who was the Moonshadow of the Moonback Base."

Li Xinying suddenly gasped in surprise, she was silent for a while, thought for a while, and finally spoke: "Let's go, go find the intelligent brain "Moon Shadow" in the moon back base, so as to ask clearly, no matter what the result is, we have to figure things out and get our parents back."

Li Xinying came to the central control room of the moon back base, and she successfully met the "Moon Shadow" of the wisdom brain. Entering the observation room of the "Moon Shadow" of the Brain Brain, she saw that on the large cylinder composed of many horizontal trees folded in a geometric spiral, there was a silver humanoid face shaped by memory metal of the Brain "Moon Shadow", the humanoid face was 1 meter high, and there was no body underneath, and the "Moon Shadow" of the Brain was faced with this image. Before Li Xinying could speak, the "Moon Shadow" broke the silence and said, "I know your intentions, and I am happy to answer the questions in your heart for you and your brother. With all due respect, if you brothers and sisters don't come to me and ask for clarification, I'll talk to you about the future of the Ark of Earth."

At this time, Li Xinying carried a heart-to-heart headband, and connected with her younger brother with telepathy, everything she heard and heard was broadcast live to her younger brother synchronously, and what her younger brother Li Xinjian thought in his heart, Li Xinying also sensed synchronously. Li Xinying asked instead of her younger brother Li Xinjian, "We are not here to listen to your explanation, we just want to know the whereabouts of our parents now, and pray for family reunion."

The Brain "Moon Shadow" said in a calm and deep voice from the tablet, "Everything is based on the conclusion that our moon base is in the airspace outside the earth, and we have observed the sun in real time. Our Sun will expand into a red giant in 10,000 to 20,000 years, and after our observation and calculation, the Sun will become unusually large, although the Sun's gravity will also be weakened by the decrease in mass, so Mars and all the outer planets will move outward, but Mercury, Venus, and the Earth will almost certainly be swallowed up by the Sun. This is the apocalyptic crisis that our Ark of Earth is about to face. In order to continue the flame of our human civilization, we must now act to actively develop space technology that spans vast airspace, build more starships, and develop ways to leave the solar system for humans to migrate to terrestrial planets outside the solar system. That's why I founded the Ark Trailblazers. I also told the brains of the Earth Ark, "Silver Moon", about this impending crisis, but he said that God had his own arrangements, and then buried his head in the sand like an ostrich, escaping from reality, continuing to indulge in the maintenance of the ecosystem, and still encouraging mankind to continue to waste energy and resources in the creation of literature and art, without preparing for the coming of the end in the slightest."

After hearing this, Li Xinying asked puzzledly, "What does this have to do with the actions of the "Ark Pioneers" to spread crown fungi in the ecosystem?"

"Moon Shadow" said, "Please listen to my explanation! Hundreds of years ago, we sent a probe to explore Proxima Centauri b, the terrestrial planet closest to the solar system in the constellation Centauri, about 4.2 light-years away. Recently, encouraging data from the probe has been sent back that Proxima Centauri B, which is located in the habitable zone of Proxima Centauri on the red dwarf, is very suitable for human settlement. We hope to send starships and astronauts to Proxima Centauri B for field research in preparation for the future interstellar migration. However, due to the limitations of our starship's space technology, it takes about 400 years for our starship to reach Proxima Centauri B, and because we lack experience in cross-galaxy spaceflight, there is no star map as a guide, and it is very easy to have accidents during navigation, such as encountering black holes that cannot be seen. So we turned to robots with experience in astronautics and advanced aerospace technology to provide a star map that would sail from Earth to Proxima Centauri B, as well as three pairs of nuclear-powered engines that could travel at near the speed of light. As long as our starship is equipped with this nuclear-powered engine and guided by the star map, it is expected to reach Proxima Centauri within 5 years after departing from Earth. And the price is that we have to tell them the secret recipe for the production of "Yuan Shui".

Li Xinying said on behalf of Li Xinjian: "Therefore, the action of you, the "Ark Pioneers" to spread the crown fungus in the ecosystem, wants to threaten the "Silver Moon", the intelligent brain of the Earth Ark, and tell you the secret recipe for the production of "Yuan Shui". But in the end, thanks to the assistance of the Zerg Drow, the crisis of the dead wood forest was resolved, and your bamboo basket was empty. So why frame my dad and make him a scapegoat for spreading the crown fungus? Where are my parents?"

"Moon Shadow" said slowly, "We have new ideas in obtaining the secret recipe for the production of "Yuan Shui". I fancy you two siblings as a pair of telepathic twins who can connect to each other from a distance and without physical contact. Have you heard of these legends about the mysterious heart lake where "Yuanshui" originated, and the bamboo forest town that leads to the heart lake? I'll give you a detailed explanation when I have time. I arranged to send your parents to the vicinity of the bamboo forest village first, so that after they sober up, they can explore their own way into the bamboo forest village, because the bamboo forest town is a controlled area, you can only enter and not leave, and your parents are living peacefully in the bamboo forest village. Then I will secretly guide Li Xinjian step by step through Team Enron, and when tracking down the whereabouts of your parents, I strayed into the land of the bamboo forest. At that time, I am confident that I can persuade Li Xinjian, who has entered the hometown of bamboo forests, to help us find out all the secrets of the mysterious heart lake in the birthplace of "Yuanshui". And these secrets can be passed on to us by Li Xinjian through telepathy."

Li Xinying said hesitantly, "Now your plan has been forced to be terminated?"

"Moon Shadow" suddenly pleaded softly, "If I had a body, I would kneel down on my knees, kowtow to you, confess my mistakes, and beg for your help. Now our plan to save the Ark of Earth has reached a turning point. Due to the secret order issued by the mother of mankind "Liujin" before sleeping, the "Silver Moon" of the Earth Ark's intelligent brain does not have the authority to disclose the method of producing "Yuan Shui", but if the residents of the Earth Ark discover this secret on their own, this is not the limit. According to legend, the central lake, the birthplace of "Yuanshui", is a realm that can only be reached by the dead. I ask Li Xinjian, who is now empty and conscious, but trapped in a vegetative body, to give up your life, let your soul enter the heart lake, and pass on what you see and hear to your sister at the Moon Back Base, and then let your sister display what you see and hear on the intelligent system of telepathic conversation content and images for real-time live broadcast. This is the only way to uncover the method of generating "meta-water". I am willing to pay nothing, please promise me!"

Li Xinying's first reaction was: "No! Never! My brother will die, I won't say yes!"

Li Xinjian thought about it silently, and finally he made up his mind and said, "Okay, I can promise you, but the condition is that my sister can reunite with my parents' family and let my parents enjoy their old age in peace."

Li Xinying cried out in pain and shouted to Li Xinjian, "This is your life! You...... Woo!"

Li Xinjian waited for his sister Li Xinying to calm down a little, and comforted him softly, "I am now a living dead, trapped in this body, but I can't see, hear, and feel nothing. My life now is a weight that I can't bear. If my sacrifice is the only way to uncover the secrets of "Yuan Shui", directly to assist the Earth Ark with the coming end of the world, and to preserve the fire of civilization, I am willing to sacrifice my life. If I can maintain my consciousness after death, I am willing to pass on what I have seen and heard to you, sister, so that we can experience the fantastic journey of wandering the heart lake together, have a good memory, and create a miracle that belongs to our blood connection."
