In the vast starry sky of the universe, there is a terrestrial planet called Mars, and now, we can see satellite photos of its uneven surface and brown-red sphere. Looking at the planets of the entire galaxy, Mars is the most enchanting one. However, as far as the eye can see, there is a barren land, a lifeless scene.

However, who would have thought that the origin of life on Mars was earlier than that of the Earth, about 4 billion years ago, life appeared on Mars, and the Earth at that time was still dead and silent, because there was no water and oxygen needed for life on the Earth at that time. At this time, there were already life species on Mars.

However, what makes us sigh and sigh is that Mars did not continue the glory and colorfulness of life species in the end, but after a nuclear explosion one after another, it cut directly from the vibrant and prosperous picture into the darkness of the catastrophe and death, and all the good things disappeared with the terrible nuclear explosion, and all of them were silent in the long river of history.

In order to explore the mystery of life on Mars, human beings have been sparing no effort to carry out various studies on Mars, all kinds of satellites and exploration instruments emerge in an endless stream, and technology and scientific and technological means are becoming more and more perfect, all of which are preparing for human beings to set foot on Mars smoothly as soon as possible.

On July 14, 2039, the Center of the Earth Space Alliance announced that it would launch a landing expedition to Mars six days later on July 20, the 70th anniversary of the lunar landing, and at that time, the Long March rocket will fly to Mars with the Mars-1 spacecraft, thus realizing the first human mission to land. The landing mission was carried out by astronaut Ai Xin and her scientific research team of the Earth Space Alliance.

Soon, on the 20th, all the personnel of the Earth Universe Alliance Center were in place, Ai Xin and her team were also ready in the spaceship, and everything was going according to plan. At this time, from the loudspeaker in the control center came the launch command of the rocket: "3, 2, 1 ignition." "The Long March rocket carrying the Mars-1 spacecraft was successfully lifted off by the booster, and slowly flew towards outer space, flying farther and farther, like a dazzling star twinkling in the night sky, until finally completely disappeared into the night.

It wasn't long before the spacecraft entered Earth's orbit, and after orbiting the Earth, the third-stage subrocket began to ignite, propelling the spacecraft into Hohmann's orbit and heading towards Mars. After more than 6 months of boring and long voyages, the Mars 1 spacecraft finally successfully entered the orbit of Mars, and with the precise operation and careful cooperation of Ai Xin and her team, the spacecraft was finally able to land safely on Mars and landed successfully at the Jezero Crater.

After the spacecraft landed, Ai Xin immediately sent back the signal of successful landing to the command center of the Earth Space Alliance, and requested that the spacecraft door be opened at the right time to officially land on Mars.

After receiving the signal from Aixin, all the personnel of the Earth Universe Alliance were excited, and after careful monitoring and judgment, the command center issued a clear order to it: take a short rest first, and then carry out the landing operation after 6 hours.

After Ai Xin received the instructions from the command center, she strictly implemented it and ordered all the staff to immediately enter a state of rest. After a long wait, six hours had finally passed, and Ai Xin sent a landing request to the command center again. After receiving clear instructions from the command center, Ai Xin hung the safety rope in the spaceship cabin on herself, and slowly opened the spaceship hatch in strict accordance with the procedure. Ai Xin could no longer hold back the joy in her heart, and slowly walked out of the hatch, when her feet really stepped on the soft gravel, she could obviously feel an unprecedented pleasure in her heart, her small step, but it represents the first time in thousands of years that mankind has truly conquered Mars, and left human footprints on its surface, you can imagine how proud it is!

However, at this moment, the Martian satellite in the control center suddenly detected a strong air flow forming and quickly rushed towards the direction of the spacecraft, which is a signal for the formation of a polar hurricane. As a result, the command center immediately sent an order to the spacecraft: a hurricane is coming, stop the landing, and immediately return to the spacecraft.

It's a pity that the distance between the earth and Mars is too far, and there is a delay of a few minutes in the transmission signal, so at this moment, Aixin, who is immersed in joy, has not been able to receive the signal from the command center in time, and she is still very excited to collect the materials needed for the experiment.

However, when she turned around after finishing this, she suddenly found that the hurricane accompanied by the sandstorm had hit her overwhelmingly, and her idea of returning to the spaceship had become difficult, but Aixin did not give up the desire to survive, only to see her tighten the safety rope one by one, and then move towards the spaceship step by step against the wind and sand. However, she still underestimated the power of the hurricane, and the powerful air currents soon blew her body into the sky, and rolled and spun rapidly, finally breaking the safety rope completely. In this way, Ai Xin disappeared into the endless desolation with the rolling wind and sand.

After the wind and sand, the other members of the spacecraft immediately repaired the damaged spaceship, and sent back to the command center of the Earth Space Alliance the video of Ai Xin disappearing by the wind and sand. Soon, the media who got the news also mixed in, and they rushed to report it, and at this time, the news about Ai Xin's abduction by aliens also spread, and the more mysterious it became! However, no matter what, it is an indisputable fact that Ai Xin was swept away by the rolling wind and sand and disappeared into the vast Mars.

Just when all the earthlings thought that Ai Xin would definitely die after this incident, she slowly opened her eyes at this time, but even she didn't know where she was, she only felt that she was floating lightly in the air, and there was a pair of snow-white wings behind her back that kept flapping, and there was a golden halo on her head.

And at this moment, in front of her, there is also an instrument similar to the pilot rudder, fixed at a glance, there are three big characters written on the fuselage: time machine, and then look at the rudder plate above, there are a total of twelve helm handles, each helm is marked with a Roman numeral, the same as human clocks, from one to twelve, but the order of the numbers is reversed. This immediately aroused Aixin's interest, and she gently flicked the rudder clockwise, and in an instant, the wind and clouds on Mars surged, and a terrible nuclear explosion was staged, and the scene was extremely bloody. Seeing this, Ai Xin couldn't bear to look directly, so she turned the rudder a few times again, this time, the picture that appeared on Mars was much milder than just now, a piece of greenery, beautiful mountains and rivers, all the beautiful pictures resurfaced one by one, but all the scenes were reversed, just like the rewind of the film. At the same time, the carved disc in the middle of the rudder wheel was also rotating, and there were several time periods marked on it, Ai Xin seemed to understand something, and turned the rudder again, until the carved disc pointed to the words marked with the words of the Heart Clan Era, and then stopped rotating.

At this time, Aixin watched everything that was happening on Mars with great interest, in order to let everyone know more about the past of Mars, now, let us trace the long river of history, through the fog of history, under the guidance of the time machine, and rewind back to the era of the heart that once happened on Mars, and at the same time follow Aixin's steps, and travel back to that glorious Martian civilization to find out.

At this point, Aixin finally understood that the first species to appear on Mars was an animal called the heart. Like us humans, the mind is also a high-level primate, they have their own thoughts and ideas, and use them to control their behavior, and they can also tame and control other creatures; They have long hands and feet and can walk freely in an upright position. The difference is that their heads and bodies are connected together, and they do not have noses and ears, and they rely on the heart eye in the upper left corner of the head to complete the analysis and processing of information. The color of each Heart Clan's heart eye is different, which is also an important sign of our identity.

Like humans, the Mind is made up of many different races, and among these races, the most representative and influential are the Spiritual Hearts. They live in the beautiful Lingxin Village.

Lingxin Village, the birthplace of the ancient civilization of the soul, a beautiful and rich place. Looking down from the sky, the entire Lingxin Village is shaped in a heart shape, surrounded by dense vegetation and mountain forests. Not only is there an abundance of products, but also beautiful natural scenery, and it is like entering a paradise of paradise, where all kinds of creatures are diverse and colorful, and the souls live in harmony with nature without being invaded by filth. Neighbors, ethnic groups live in harmony, freedom and equality; The road is not forgotten, and the night is not closed; The people are simple, each has its own place, and the fruits of their labor can also be respected, and life can be described as happy and beautiful; The social atmosphere is peaceful and peaceful, and things are useful, materials are used, and they are suitable everywhere. Fairness and justice are the most deeply rooted symbols of civilization in this historical period.

It can be seen that Lingxin Village is truly a blessed land, and it can be regarded as the most beautiful gift that the Creator has given to his people, so that they can multiply and live freely and happily here.

Next to Lingxin Village, there is a river called "Pure Heart River" that flows from afar, and flows through here before flowing to the sea. Walking along Lingxin Village into the mountains and forests, you need to pass through a low-lying valley, which the ancestors called "Lingxin Valley"; Walking through the "Lingxin Valley", you will come to the place where the tribesmen often hunt, they call it the "hunting area", in the mountains and forests of the "hunting area", there is a three-way road leading to three different places. The mountain road to the left winds around the mountainside of Lingxin Mountain, and further on is two mountains in front of you, after crossing these two mountains, you will come to a flat and open mountain forest, which is the living circle where wolves gather, if you can successfully pass here, and then cross a "barricade river", you can come to a place called "Gold Rush Mountain", which is the place where the legendary treasure is located. The people of Lingxin Village dreamed of this, but many gold diggers were eaten by wolves in the middle of the road before they could reach their destination, and in the end, no one dared to rush there again.

Walk straight forward from the three-way road and climb to the top of Lingxin Mountain, from where you can see the panoramic view of Lingxin Village and the sea in the distance.

Walk right from the three-fork road, pass through an open mountain forest, and come to the upper reaches of the "Jingxin River", because the river is relatively narrow, the ancestors have built a ropeway pontoon bridge here, and then go to the depths of the mountain forest after passing the ropeway pontoon, which is the Bear Mountain. Similarly, the people of Lingxin Village generally do not dare to rush into this mountain, and it is said that all the people who enter the bear mountain have no return, because the black bears there are strong and powerful, once they are unfortunate enough to meet them, then, waiting for the judgment of fate will be an inescapable catastrophe, therefore, the people do not dare to go to the offense easily.
