Xiao Yi concentrated on using his supernatural powers on the old man, carefully adjusting the flow of energy to help him regain a steady breathing. His hands danced in the air like an elegant dancer, showing endless charm in the dancing light and shadow.
After a period of effort, Mr. Yu's breathing finally became steady. It was a kind of life force, a call of hope. At this moment, the two of them were filled with relief and joy.
After settling her grandfather down, Yu Wei seemed a little panicked and held Xiao Yi's hand tightly, with cold sweat on her palms.
Xiao Yi hugged Yu Wei comfortingly, but he was also a little worried. Actually, this cold snap wasn't entirely a bad thing. At least for now, no one would be able to start a riot. After all, in such a temperature, no matter how much you wear, it probably won't help. If you want to withstand such low temperatures, even if you wear warm clothes, you won't be able to move freely in the east.
In order to ease Yu Wei's tension, Xiao Yi changed the subject and asked, "Have you ever thought about the terrible impact of such an extreme cold snap?"
Yu Wei didn't think much about Xiao Yi's question when she heard it, and began to mechanically repeat what she had learned from the textbook: "Super low temperature usually refers to conditions in extreme environments where the temperature is far below normal. When the temperature drops to very low levels, a series of interesting and terrifying phenomena will occur."
"First, let's consider the state of matter. At extremely low temperatures, matter undergoes a phase transition, changing from liquid to solid, a phenomenon known as freezing. For example, when water drops below 0°C, it freezes into ice. This is because the kinetic energy of water molecules decreases at low temperatures, making it unable to remain liquid, and instead becomes solid. Furthermore, some gases, such as oxygen and nitrogen, also condense into liquids at low temperatures."
"Secondly, ultra-low temperatures will also affect the physical properties of materials. At low temperatures, the thermal expansion coefficient of materials will decrease, which means that the volume of the material will be more stable. In addition, the electrical conductivity of the material will also be affected. As the temperature decreases, the electrical conductivity will decrease. This is because the movement of electrons is hindered at low temperatures. Because at low temperatures, the lattice vibration of the material slows down, making the migration and transfer of electrons easier. This phenomenon is called "superconductivity." In the superconducting state, electric current can flow without resistance, but at present, it is estimated that electronic products will be difficult to use under such low temperature conditions."
"At ultra-low temperatures, the chemical properties of substances will also change. For example, the rate of some chemical reactions will slow down or even stop completely. This is because the kinetic energy of molecules decreases at low temperatures, making it difficult for chemical reactions to proceed. Therefore, laboratories generally require a constant temperature of a certain number of degrees above zero. Even at low temperatures, it will not be that cold."
"Ultra-low temperatures also affect the magnetism of materials. At low temperatures, the magnetism of some materials becomes stronger because the interaction between spin electrons is more significant at low temperatures."
"In addition, super-low temperatures can also affect the movement of celestial bodies. In the universe, some celestial bodies experience very low temperatures during their formation. These low temperatures can affect the shape, size, and trajectory of celestial bodies. Mars colliding with a blue planet is possible."
"In addition, ultra-low temperatures also have an impact on life. Under extremely low temperatures, the metabolism of most organisms will slow down or even stop, allowing them to survive in extreme environments. This phenomenon is called 'cryopreservation'. However, not all organisms can survive at low temperatures. Some organisms will lose vitality or even die at low temperatures. Many ancient organisms have been found in glaciers tens of thousands of years old."
"To sum up, we can predict and be prepared to deal with possible situations at any time. In this contest, the oldest method may be the most direct, but it is often also the most effective strategy." Yu Wei's voice was a little nervous at first, but gradually became confident, like the notes jumping on the strings, which made people feel at ease.
Xiao Yi listened to this, feeling relieved. He couldn't help but feel overwhelmed. Everyone should shine in their own field of expertise. Their satisfaction and confidence are like the morning sun, warm and healing. This kind of confidence and satisfaction is like a panacea, healing the pain in people's hearts and revitalizing them.
Yu Wei's words flowed slowly from the textbook like a mechanical recitation. However, hidden in this cold recitation was the most crucial information, like a clear stream, gurgling. And Xiao Yi's eyes flashed with praise, encouragement and warm comfort.
Xiao Yi took a swig of the spiritual spring water from the space, feeling instantly refreshed. He decided to let Yu Wei sleep peacefully while he himself would keep watch. On this frigid night, the extreme cold followed like a shadow, invading the world with every pore. To withstand the severe cold, people racked their brains to find ways to stay warm, ignoring the potential damage. However, on this night with unpredictable temperatures, it was wise to leave one person on duty to sense the subtle changes in this cold world and prevent the entire team from freezing unknowingly.
Yu Wei obediently donned his eye mask and quietly slipped into bed on the sofa, soon settling into a sweet dream. His breathing gradually evened out, as if he were telling a peaceful story. Meanwhile, Xiao Yi began packing warm clothing, meticulously arranged for Old Man Yu, Ye Ming, himself, and Yu Wei, ensuring they could respond swiftly to any emergency.
In the living room, two fires were blazing. The larger fire crackled fiercely, while the kerosene stove in the middle of the living room also burned brightly. The steel hearth had been burned red by the high temperature, and the bursts of heat made people feel a little dry. However, Xiao Yi still felt it was not enough. The shadow of his past life followed him like a shadow, making him deeply afraid and worried about the cold.
As night fell, Xiao Yi put on his headphones, immersed in the world of movies. However, as he summoned the space, his taste buds were awakened by the fragrant shrimp wontons and two sizzling beef patties. Body? Oh, what are you thinking about? At this moment, the most important thing is to replenish calories!
Imagine those living in extremely cold regions. What kind of food wouldn't be rich and rich? Or perhaps full of sweetness? After all, in freezing weather, eating less really doesn't keep you warm. It's like a blazing fire in the freezing cold, and food is that fire, bringing warmth and comfort.
Xiao Yi took a bite of the shrimp wontons, and the delicious taste of the plump shrimp and delicate wonton wrapper instantly bursting in his mouth made his eyes light up. This was the taste of the extremely cold regions in his mind, greasy and full, like a barrier against the cold. And the two large beef patties reminded him of those days of struggling in the ice and snow, a taste full of strength.
However, food brings more than just satisfaction and enjoyment; it also brings a love for life and hope for the future. Just like those people who persevere in the extreme cold, they use food to motivate themselves and heat to drive away the cold.
Xiao Yi enjoyed the warmth and satisfaction brought by this delicious food, and his heart was full of expectations for the future. He knew that no matter how many difficulties and challenges lay ahead, as long as he had this love for life and pursuit of delicious food, he would be able to move forward courageously.
