Chapter 322 Breathing Mask
Lu Cheng quickly composed himself and looked at Qin Jiu, saying, "I'm fine now. You don't need to stay with me. Go chat with them."
Qin Jiu was a little worried: "Are you really alright? You seem like you've lost your soul..."
"It's really nothing," Lu Cheng feigned surprise. "Why are you suddenly so concerned about me? Could it be that you like me?"
Qin Jiu retorted angrily, "Stop flattering yourself! Who likes you?"
She stormed off.
Lu Cheng was still smiling, but there was an inexplicable sense of desolation in his smile.
Looking at the bustling crowd in the distance, he suddenly felt a sense of loneliness.
The next moment, a pair of hands grabbed his arms.
"Stop pretending to be profound, come and chat!" Qin Jiu said without waiting for a reply, pulling him towards the crowd.
Watching her retreating figure, Lu Cheng felt his heart beat faster.
Everyone chatted and laughed, filling the car with cheerful conversation.
Soon, the conversation turned to the demonic energy invasion. They all talked about their symptoms today and looked at Qin Feng.
Qin Feng's expression turned serious: "The turbid demonic energy can indeed harm the human body, and there is no cure for it."
"No cure?" Qin Jiu exclaimed in shock. "Does this mean we'll be stuck in this situation forever?"
Meng Qingyin, however, grasped the key point: "Turbid demonic energy? Could it be that all the demonic energy in the Tower of Babel is turbid demonic energy?"
Qin Feng gave her an approving look. "That's right. The demonic energy in the Demon Tower is turbid and mixed. If a person inhales too much of it, it will cause various discomforts."
Meng Qingyin suddenly thought of [spider silk].
The description says that spider silk can be used to extract demonic energy, which means...
"Is the demonic energy extracted from the spider silk no longer turbid demonic energy?" Meng Qingyin asked.
Qin Feng nodded: "You are very perceptive. As for your concerns about the harm that the turbid demonic energy may cause to the human body, there is no need to worry about that. The turbid demonic energy will dissipate over time."
Meng Qingyin looked at her intently: "You must have a way to block these turbid demonic energies, right?"
Qin Feng smiled: "I have been studying demonic energy for many years, and just a few days ago I developed a breathing mask that can prevent the inhalation of too much turbid demonic energy."
As she spoke, she took out a mask, somewhat similar to an oxygen mask, but with a very simple design and nothing particularly special about it.
But Meng Qingyin knew that it was definitely not as ordinary as it looked.
"Sister Feng, how many of these breathing masks do you have?"
Such a seemingly simple mask can prevent demonic energy from corroding the human body, and players will definitely be happy to buy it.
Qin Feng saw through her intention and shook his head with some regret, "I only made one, and I still plan to keep it for myself."
Meng Qingyin was somewhat disappointed. If there was only one person, it wouldn't be very effective. Their team consisted of five people, and at least all five of them needed to wear breathing masks.
Qin Jiu examined the mask closely, and after a moment asked, "Is it really impossible to mass-produce it?"
Qin Feng: "The main difficulty in mass production is the need for a large amount of pure demonic energy." She shrugged, somewhat helplessly, "The Tower of Babel is a bit difficult for me, so obtaining pure demonic energy is very, very difficult."
Meng Qingyin: "How much pure demonic energy is needed to make a breathing mask?"
Qin Feng: "Only 10ml is needed."
Meng Qingyin then asked, "How much pure demonic energy can be extracted from a single spider silk?"
Qin Feng: "1L".
Meng Qingyin asked in confusion, "1L? That's enough to make 100 breathing masks?"
Qin Feng rolled his eyes gracefully. "I was just saying you were smart, and now you're starting to act stupid."
Meng Qingyin: "???"
Qin Feng: "Guess how I made this breathing mask that can block out turbid demonic energy?"
Meng Qingyin pondered for a moment and understood; it must have involved a lot of experiments and consumed a lot of pure demonic energy.
Seeing that she understood, Qin Feng added, "Besides, I also need pure demonic energy to research demonized equipment. For me, there's not enough pure demonic energy."
Meng Qingyin took out all her spider silk and magic-absorbing stone. "Sister Feng, this is all my spider silk and a magic-absorbing stone. Could you please make a breathing mask out of it for me? As payment, I'll give you a piece of spider silk so you can continue your research. Oh, and my friends also have quite a bit of spider silk, could you please help them with that too…"
Qin Feng raised his hand to interrupt her, "There are too many, we can't do them all."
Meng Qingyin choked.
Qin Feng: "Do you think I'm a machine on an assembly line, capable of making so many breathing masks by myself? Here's what I'll do: I can make one for each of you, but I really can't make any more than that."
Meng Qingyin: "Then why don't you tell me how to make a breathing mask, and I'll make it myself? Of course, this is your research result, and I'm willing to pay for your knowledge."
This time, Qin Feng didn't refuse: "Are you sure you want to buy the recipe for making the breathing mask? Let me tell you, the process is very complicated."
Meng Qingyin simply said, "Name your price."
Qin Feng: "How about this, just give me ten spider silk threads."
Meng Qingyin's expression was somewhat strange. "Just ten spider silks?"
Qin Feng looked at her in surprise, "You still think it's not enough?"
Back then, she finally managed to assemble a five-person team to enter the Tower of Babel, but it took her more than ten tries to clear just the first floor.
As for the second level of the Spider Silk Bursting event, they had to farm it no less than twenty times before finally obtaining a single spider silk.
As a result, the five of them nearly met their grandmother due to the corruption of demonic energy.
How did she know that demonic energy could corrupt the human body?
They are all stories of blood and tears, of people who have become good doctors through long illnesses.
Later, she used the pure demonic energy extracted from that spider silk to develop a breathing mask, and she also wanted to research demonized equipment. She really wished she could split a spider silk in two for use.
Mengmeng actually thinks ten is too few?
She felt a little guilty even asking for ten spider silks!
If Qingfeng finds out that she stole ten spider silks from her master, he might sever all ties with her!
After all, Qingfeng was one of the team members who almost met Grandma, so she knew very well how difficult it was to obtain spider silk.
Fearing Qin Feng might change his mind, Meng Qingyin readily agreed: "Deal!"
Qin Feng also secretly breathed a sigh of relief.
Both of them seemed guilty about the deal, yet felt they had gotten a great deal.
Of course, Meng Qingyin didn't have ten spider silks right now, so Chen Leying helped her make up the rest and gave them to Qin Feng all at once.
Qin Feng held the ten spider silk threads as if they were precious treasures.
Just then, Qingfeng arrived.
Qin Feng subconsciously hid the spider silk behind his back, looking guilty and nervous.
Qingfeng noticed something was wrong with her. "What's wrong?"
Qin Feng dared not utter a sound.
Qin Jiu spoke frankly: "Sister Feng just traded ten spider silks with Mengmeng."
Qingfeng paused, clearly recalling that painful memory from the past.
However, she didn't say anything and went straight to the table to get a piece of strawberry cake and started eating.
