Chapter 48 Rescuing People from Multiple Illnesses
Wu You took out a lamp from the old house's space, and under the cover of darkness, pretended to take it out of a package. He said to the two of them, "I brought a lamp with me. Young Master Fang, you go and continue to check the mechanism. Li Lianhua and I don't understand it either, so we can only rely on you."
Wu You turned on the desk lamp, and a soft light spread out, illuminating the features of the three people in front of her.
Fang Duobing was surprised: "I didn't expect Miss Wu to carry a torch with her. But how did you manage to fit such a big torch into your bag? I couldn't even tell."
Wu You chuckled and said, "My package looks small on the outside, but it's packed with stuff inside. You could call it a treasure trove."
Li Lianhua, who was standing next to her, immediately recognized it as the desk lamp that Wu You had placed in her room many years ago. He said that the candlelight was too bright for his eyes when he was reading at night, but the style was slightly different.
Fang Duobing asked with some curiosity, "Why can your torch be lit, but why did you make me extinguish mine? Wouldn't it last longer if we used both?"
Li Lianhua also looked at Wu You with curiosity.
That's a good question. Wu You still needs to explain to them what oxygen is.
"Oxygen is an elemental substance formed from oxygen, with the chemical formula O2. It is chemically reactive, and most elements can react with it. At room temperature, it is not very reactive and does not readily react with many substances."
Oxygen is a colorless and odorless gas, and it is the most common elemental form of oxygen. Its melting point is -218.4°C, and its boiling point is -183°C. It is sparingly soluble in water; approximately 30 mL of oxygen dissolves in 1 L of water. Oxygen makes up about 21% of the air. Liquid oxygen is sky blue. Solid oxygen is a blue crystal.
Oxygen is the most abundant element in nature, making up 48.6% of the Earth's crust. It is needed in various processes, including hydrocarbon oxidation, wastewater treatment, rocket propellant, and for respiration in aviation, aerospace, and diving. Animal respiration, combustion, and all oxidation processes (including the decomposition of organic compounds) consume oxygen. However, atmospheric oxygen is continuously replenished through plant photosynthesis. In metal cutting and welding, oxygen with a purity of 93.5%–99.2% is mixed with combustible gases (such as acetylene) to produce extremely high-temperature flames, thus melting the metal. Metallurgical processes cannot function without oxygen. Oxygen is also required to enhance the production of nitric acid and sulfuric acid. Using a mixture of oxygen and water vapor instead of air in a gasifier produces high-calorific-value gas. Medical gas is extremely important.
(This article is from the internet. I originally just wanted to write something casually, but after thinking about it, I decided to post it properly. Readers who find it boring can skip it.)
Seeing the bewildered looks on their faces, Wu You knew they hadn't understood. However, she had only repeated what she had read online, and she wasn't entirely clear on the specifics of what she had said.
Wu You put it another way: "Simply put, there's something called oxygen in the air we breathe, and a torch also needs oxygen to burn. This is a closed space. If the torch burns out all the oxygen, we won't be able to breathe and will suffocate. Do you understand now?"
Now, the two bewildered people finally understood and nodded.
"But why is your torch still on? Turn it off quickly, saving your life is the most important thing." Fang Duobing urged Wu You, trying to blow out the lamp.
Wu You quickly stopped him, saying, "This isn't a torch; it won't consume oxygen."
Fang Duobing was like a curious child, staring intently at the desk lamp, asking a million questions. "This young master sees that it's definitely different from ordinary torches. How is it different from that other torch?"
Wu You picked up the desk lamp and shoved it into Fang Duobing's hand: "Ask so many questions, do you still want to get out of here? Hurry up and find the mechanism, and shut up, okay? We'll talk about this later."
"Oh." Seeing Wu You's fierce look, Fang Duobing stopped talking and picked up the lamp again to search carefully, looking aggrieved.
Since everyone here was a familiar face, and there was no need to wear a mask anymore, Wu You took off the fox mask from his face and slowly exhaled a breath of stale air.
Seeing this, Li Lianhua also reached behind her head to untie the straps, took off the fox mask, and placed it together with Wu You's.
Unexpectedly, after so many years, Li Lianhua has transformed from a somewhat naive girl into a mature woman, a different kind of heart-fluttering beauty.
Over a year of suffering from the poison of the Jade Tea had slightly altered Li Lianhua's face, making him appear somewhat familiar. However, if one knew it was originally him, the difference would be negligible.
Fang Duobing turned around and saw two fox masks piled together, which puzzled him. Looking at Li Lianhua's face, it seemed somewhat familiar. He leaned closer for a closer look, and a sense of familiarity washed over him.
"Li Lianhua, do you think we might have met before? You look so familiar. I feel like I've seen you somewhere before?" He blinked his big eyes and stared at Li Lianhua intently.
“How could we know each other? Think carefully, have we ever met? It must be a matter of lighting angle.” At this moment, Li Lianhua did not want to respond to Fang Duobing at all, but just quietly looked at Wu You.
To everyone's surprise, after so many years, Wu You's face had matured considerably. You couldn't tell from his face that seven or eight years had passed; he looked like he had only been gone for three or four years.
Fang Duobing nodded: "That's right, if you've seen it before, you should remember it." He stroked his chin thoughtfully, muttering to himself, "No, I must have seen it before, otherwise why does it feel so familiar? Where have I seen it before?"
Unable to understand it, Fang Duobing had no choice but to continue what he had been doing before.
Unable to leave anytime soon, Wu You placed his bundle next to Li Lianhua and simply sat down.
Watching Fang Duobing's busy figure, Wu You asked Li Lianhua beside him, "Do you think I'm being a busybody by looking for that small cauldron, which is why the three of us are trapped here?"
Hearing Wu You's self-blame, Li Lianhua quickly comforted her: "Didn't you say that if this thing fell into the hands of bad people, it would harm the martial arts world? You just controlled it in advance, which was a good thing. It was that person in the outer passage who harmed us. You don't need to blame yourself."
Upon hearing this, Wu You felt somewhat better. However, at this moment, Wu You was still preoccupied with looking at the sky, the ground, and the surroundings, and dared not look at Li Lianhua, much less look him in the eyes.
Whether it was because Fang Duo was ill and Li Lianhua couldn't speak frankly, or whether Li Lianhua simply wanted to see Wu You feel guilty, Wu You remained uneasy until the matter was clarified.

Fang Duobing: It's clear that Li Lianhua and I have perfect chemistry and coordination, so why do I feel like you two are keeping everything under the table and excluding me?
Wu You: You don't understand.
Li Lianhua: You don't need to understand.
Fang Duobing: Sigh, I also want to understand, but do I really need to understand?
