I've been reborn, who still chases the school hunk?

The alien took the drawing and looked at it attentively. His eyes moved slowly on the drawing, as if he was looking for some important information. However, after a while, a confused look appeared on his face.

"I'm sorry, our technology has not yet developed to the point where we can conduct interstellar travel. We only have this ancient star map to provide you with as a reference." Lu Xuanxin explained apologetically, her tone full of helplessness and regret.

The alien's four eyes quickly scanned the star map, and a look of disappointment appeared on his face. He seemed to be looking for a way home, but the star map did not bring him much help.

"It doesn't matter. According to your star map, I may be in a very remote star region now... It may be difficult for me to return to my planet." His disappointment was evident in his words, and his voice revealed a deep sense of powerlessness.

"And..." The alien felt his body, sighed softly, and said to Lu Xuanxin and others, "My physical condition is very bad, and my energy loss is serious. I'm afraid I won't live long." His tone was full of sadness and helplessness.

"Is there anything we can help you with?" Lu Xuanxin asked with concern, her eyes full of sympathy and worry.

"There is no other way." The alien said calmly, "If I could return to my home planet, my injuries might be healed, but you don't have the ability for interstellar travel, so you can't do that." His voice revealed a deep regret and helplessness.

Hearing this, Lu Xuanxin was stunned, with a hesitant expression on her face. She seemed unable to accept this cruel reality, but she was powerless.

The surrounding scenery became extremely heavy at this moment, as if even the air had frozen. Everyone fell into silence, with only the alien's breathing echoing in the air.

"If you have any questions, ask them now! According to your planet's time, I have less than one twelfth of a day left to live." The alien's language was a little stiff, but still understandable. A bitter smile flashed across his face, as if he was mocking his own fate.

Is this alien going to die in two hours? An inexplicable sense of urgency surged in everyone's hearts.

"Can the civilization of your home planet exceed the speed of light?" Lu Xuanxin asked curiously. She was trying to understand the level of this alien civilization.

"No." The alien shook his head, his eyes revealing a deep helplessness. "The speed of light cannot be surpassed. The fastest spacecraft we have built can only travel at a speed of 280,000 kilometers per second. When the speed approaches the speed of light, the energy required increases dramatically, which makes interstellar travel extremely uneconomical and difficult."

"Then how do you conduct interstellar travel?" The aerospace expert next to him couldn't help but interrupt. His face was full of confusion and curiosity, as if he wanted to uncover the mystery of this alien civilization.

"The universe is so vast and boundless. If there is no way to exceed the speed of light, wouldn't interstellar travel become a fantasy?" the aerospace expert continued to ask.

The alien didn't even look at the aerospace expert, but continued to stare at Lu Xuanxin. He slowly said, "The universe you understand is not flat, but has curvature. You can imagine the universe as a large membrane, its surface is curved, curved, or even closed, like a soap bubble. Although the membrane appears flat locally, the curvature is everywhere and at all times."

He paused and continued, "A massive celestial body will cause a dent, just like a stone pressing on a membrane, and the space we are in is actually multi-dimensional. These membranes of different dimensions may squeeze and connect with each other. When we travel between stars, we don't need to fly in a straight line. Instead, we can find and use these connection points at the spatial level - that is, wormholes - to travel directly through. But this method of travel cannot be achieved by ordinary spacecraft engines. It requires a special engine - a curvature engine to drive it. However, the energy consumed by this engine is very huge."

After hearing the aliens' explanation, the surrounding aerospace scholars fell into deep thought. They began to re-examine their own cognition and understanding of the universe and tried to integrate this knowledge into their own research fields.

So that's it! The confusion in everyone's mind gradually dissipated, replaced by awe and desire to explore the unknown.

In fact, humans on Earth have also studied and achieved certain results in advanced space travel technologies such as curvature engines and wormhole shuttles. However, compared with this alien civilization, the technological level of humans on Earth obviously still has a long way to go.

"I want to ask how you came to our planet?" Lu Xuanxin asked seriously, "When we detected your lifeboat, it was surrounded by a large number of meteorites, which almost brought disaster to our planet!" Her tone revealed a sense of accusation and dissatisfaction. At the same time, she recalled the memory fragments she saw in the water droplets - the thrilling escape process and the subsequent meteorite rain attack.

Could it be that this alien encountered a world-shaking cosmic war that caused the spaceship to be destroyed, the life capsule to be automatically ejected, and it ended up here? Lu Xuanxin guessed in his mind and waited for the alien's answer.

"I'm deeply sorry for the trouble and distress I've caused you!" The alien first apologized and explained, "We are a member of an interstellar fleet from a distant galaxy. While exploring the ruins of other civilizations, we were unexpectedly attacked by a mysterious creature called the 'Starry Sky Ancient Beast'. We tried our best to escape the ruins and tried to drive the spacecraft out of the danger zone, but unfortunately those ancient beasts destroyed our entire fleet."

"My life capsule automatically popped out and escaped the scene when the spacecraft was destroyed. I don't know what happened afterwards. When I woke up, I was already on this strange planet!" At this point, a trace of bitterness and helplessness flashed in the alien's eyes, as if he was recalling the thrilling escape experience and the various difficulties and setbacks he encountered afterwards.

After hearing this, Lu Xuanxin was stunned for a moment and fell into deep thought. She originally thought that this alien was stranded here because of an interstellar war, but now it seems that things are not that simple. It also involves a more complex and mysterious cosmic creature - the ancient star beast!

Before Lu Xuanxin could continue asking questions, Academician Wu next to him couldn't wait to ask the alien: "Can you give us a detailed introduction to what those ancient star beasts look like? They can actually destroy an entire interstellar fleet. This is simply incredible!" His face was full of shock and curiosity, and he was obviously very interested in this topic.

"We don't know much about the origin and specific information of the ancient star beasts." The alien sighed and explained, "Since we mastered the technology of flying across space, we have gradually discovered the existence of these mysterious and powerful creatures. They are widely distributed in various dangerous areas of the universe and come in many species and various shapes!"

"Most of these ancient beasts have no intelligence but possess extremely strong defense and attack capabilities! After surviving in the wilderness of the universe for countless years, they have evolved extremely terrifying combat capabilities! What's even more deadly is that the weaker ones often live in groups while the stronger ones are as huge as planets!"

After hearing this, everyone was stunned! They couldn't imagine how terrifying and powerful those beasts as big as planets were! This was simply beyond human comprehension!

"Most of them are not the carbon-based creatures we are familiar with!" After seeing the confused and shocked expressions on Lu Xuanxin and others' faces, the alien added, "In fact, our home planet also has very limited knowledge of this kind of mysterious creature. I once studied an ancient star beast living in the asteroid belt of the neighboring Berta galaxy group. Let me use it as an example to explain it to you!"

"That ancient beast is about 300 meters in size. It is a silicon-based creature that lives in groups in the asteroid belt and feeds on meteorites!" The alien began to describe the characteristics and living habits of that mysterious creature in detail. "They usually have extremely strong defense and speed and are huge in number! Ordinary civilizations dare not provoke them easily, otherwise they will pay a heavy price!"

After hearing the alien's description, the scientists around him were deeply confused. Their eyes revealed their confusion about the existence of this alien. His appearance and his knowledge were far beyond the scientists' original cognition. The "ancient star beast" mentioned by the alien made them even more confused. This term sounded like a fairy tale to them, and they could not understand the meaning behind it.

On this familiar yet strange Earth, they knew nothing about the vast universe, just like a frog in a well, only able to see a small piece of the sky. However, just when the scientists seemed a little confused and at a loss, a figure walked out of the crowd. It was Lu Xuanxin.

She stood aside, looking at the alien with a firm gaze, and decided to break the silence. "I have a question for you!" Her voice was clear and loud, echoing in the empty laboratory.

The alien turned his head and looked curiously at the woman who had the courage to ask the question. "What's the question?" he asked gently.

Lu Xuanxin took a deep breath and took out a mysterious teardrop-shaped object from her pocket. The object was crystal clear, as if it contained some unknown power. She showed the object to the alien, her face full of confusion: "Do you recognize this thing? What is it?"

When the alien saw the object, he showed an expression of disbelief on his face. He stared at the teardrop-shaped object with wide eyes, as if he was recalling something. "I was wondering how this thing got lost, and it turns out you found it!" He said thoughtfully, with a hint of surprise in his voice.

He explained to Lu Xuanxin: "We found this object in the ruins of a distant ancient civilization. At that time, we ventured deep into the center of the ruins and went through untold hardships to get it. However, at the moment we obtained this object, we were suddenly attacked by the ancient star beast. It was a thrilling battle and we were forced to flee from that dangerous place. During the escape, this object was accidentally lost. Unexpectedly, it would appear here."

At this point, he showed a bitter smile. "As for what this thing is, we haven't had time to study it in depth. Its function and purpose are also a mystery to us. Now it seems that this mystery needs to be solved by you!" He solemnly handed the water drop-shaped object back to Lu Xuanxin.

Lu Xuanxin took over this unknown object, his heart full of doubts and curiosity. Relics of ancient civilization? So, the memories recorded by this teardrop-shaped object have no direct relationship with the aliens' home planet. So, what secrets does it hide?

The scientists nearby also came to their senses at this moment and asked questions to the aliens. "What is the name of your home planet? Are there really many aliens in the universe? Are there civilizations that span galaxies?" The scientists' eyes were shining with enthusiasm. They knew that this was a once-in-a-lifetime opportunity, a great chance to understand the starry sky and explore the unknown.

Lu Xuanxin also showed a curious look, looking forward to the alien's answer.

The alien looked at the group of curious humans in front of him and began to explain the vastness of the universe and the diversity of civilizations. "We call civilizations like yours that have not yet traveled to the stars a native civilization. With the development of technology, you will gradually control your own star system and achieve short-distance interstellar travel. At this time, we call it a Type 1 civilization. More advanced civilizations have mastered the technology of curvature engines and can move freely between star systems. This is called a Type 2 civilization. When a civilization develops to the point where it can control all the resources of an entire star cluster, we call it a Type 3 civilization."
