Chapter 67 Reversal Middle School (16) - Obtaining Copper
Ning Shu, who was exhausted and lying on her dormitory bed, couldn't sleep because she was worried about the big exam in a few days. For the first time, she felt the pressure.
When there are clues in other instances, as long as they work hard to cooperate with the mission, they can clear the instance smoothly.
This dungeon is like a joke; you're almost there to get the items that help you clear the dungeon, but you just can't get them, which is really frustrating.
While her NPC roommates were discussing the big exam, Ning Shu, though not hopeful, still asked them a few questions about the experimental materials.
“Why are you asking this, you who doesn’t wash his feet? The big exam won’t be about experiments, you just need to know how to do the questions,” roommate A replied.
“Exactly, don’t waste that time, doing practice problems is the key,” roommate B chimed in.
They answered all at once, but not a single useful word came out.
Ning Shu felt she could finally go to sleep, knowing that there was still a lot of hardship and exhaustion to endure tomorrow.
The next day, when Ning Shu and the others wanted to ask for leave again, the teacher refused.
Ning Shu really didn't want to risk creating clones for Monkey King and the others, so early in the morning, she and Cheng Chuan went to see their homeroom teacher first.
They threatened the other party and got the homeroom teacher to issue sick leave certificates to the group of students, which were extended to the day before the big exam.
Although they all had sick leave certificates, they were worried that they might not know what was going on in class, so they left Wu Yi to teach the class.
They agreed that every time the bell rang, Graffiti would activate his innate skill, and Wu Yi would find a place to explain the situation, which Graffiti would then relay.
This was the easiest mission Wu Yi had ever taken, and he happily accepted it.
The remaining five people split into two groups to search for items related to copper.
Yesterday, Wu Yi and Tuya not only asked the chemistry teacher, but also the librarians, and their answers were all to tell them to go to the lab to find it.
The answer was expected, and Ning Shu and the others were not too disappointed.
After searching for another morning, Ning Shu couldn't take it anymore and collapsed into a chair.
"I wonder how Monkey and the others are doing with the search," Graffiti couldn't help but say. "They wouldn't have found it and not told us, would they?"
"It shouldn't be that bad; it wouldn't benefit them unless they were willing to abandon a teammate."
Tell us, and we'll have a win-win situation; otherwise, neither of us can survive.
Cheng Chuan analyzed that he felt Monkey King was a smart man and should know how to weigh the pros and cons.
"Think about it, what items in our lives must be made of copper?" Ning Shu suddenly blurted out.
After a moment of silence, Tuya suddenly spoke up: "Sister Ning, I've thought of one, but it might not be usable."
The graffiti suddenly acted like a primary school student reporting to the teacher, raising its right hand and saying something.
Tell me about it.
"When I went to look for the list, I noticed some trophies in some cabinets in the registrar's office. If they were bronze awards, would they be made of bronze?"
"...Bronze Award is a proper noun, a formal term. You could use a broken stone to represent a bronze award, that would be fine too," Cheng Chuan couldn't help but explain.
"Oh, I see. I'll think about it some more," the graffiti said dejectedly.
Cheng Chuan: "I did think of one: the lock cylinder. Lock cylinders are usually made of copper."
Ning Shu: "Lock cylinders can also be made of alloys. The key is, even if you get the lock cylinder, how do you put it into a container to conduct experiments?"
To prevent sulfur dioxide leakage, the container must be sealed.
Do beakers or wide-mouthed bottles have stoppers that big? "The stopper has to have a hole in it."
Cheng Chuan: "If there's no better way, I think I can give my method a try."
Ning Shu suddenly had a flash of inspiration; how could she have forgotten about this?
Ning Shu smiled mysteriously: "I've thought of one, but it's a bit dangerous."
Looking at Ning Shu's confident expression, Cheng Chuan knew without asking that her method must be reliable.
Ning Shu asked Tuya to replace Wu Yi, as she needed Wu Yi's help. Before leaving, Tuya made a point of verifying this.
"Sister Ning, you've come up with a solution, you won't abandon me, will you?"
"...What are you thinking about? Hurry up, do you think we can escape your ears when we do something?"
Ning Shu rolled her eyes at him, but Tuya thought it made a lot of sense, so she happily went off.
After waiting for a while, Wu Yi finally arrived, and he ran to Ning Shu's side, panting.
"Sister Ning, I heard you were looking for me."
Ning Shu looked at him and said, "No need to rush, we'll wait for you."
"What do you want?"
Wu Yi was curious. He thought he would just continue attending classes until the end of the dungeon, but he didn't expect Ning Shu would need his help.
"Come on, there's something I'd be better suited to do." Ning Shu said, glancing at Cheng Chuan, who immediately understood.
The three of them found a school storage room so that they could make less noise later.
"Is what we need here?" Wu Yi asked curiously.
Ning Shu and Cheng Chuan were groping around on the wall, and Wu Yi asked curiously, "What are you looking for?"
"The switch," they both answered in unison.
Since it was broad daylight, they didn't need to turn on the lights, but for safety reasons, they still wanted to turn off the main power switch.
Ning Shu's solution was to pull out the electrical wires from the house, peel off the outer insulation, and reveal the copper underneath.
Moreover, since it's copper wire, it can be put into a container for experimentation without any processing.
No, the only solution is to coil them into a spiral shape, like a spring, to increase the contact area with the solution during the experiment.
"Did you find it?" Ning Shu asked Cheng Chuan.
"No, maybe the switches are located in other places?" Cheng Chuan wondered.
"Then it would probably be hard to find. Luckily, we called Wu Yi over, otherwise it would have wasted so much time." Ning Shu was pleased with his foresight and looked at Wu Yi.
"Martial arts, it's up to you now."
Wu Yi then realized that they had summoned him to remove electrical wires—how dangerous! [1]
"I...I won't die, will I?" Wu Yi swallowed hard.
"You can just petrify yourself; rocks don't conduct electricity." Cheng Chuan was speechless. Couldn't he have some common sense?
Wu Yi then activated his skill in front of them, dismantled a lamp, and pulled out all the wires inside.
The moment the power line detached, the entire house remained silent.
Great, although they couldn't find the switch, the wires must have been installed separately.
"It's really okay, I took it out, look!" Wu Yi smugly showed off in front of them, holding up the wire.
"Alright, hurry up and dig out a few more so we can leave as soon as possible. We don't know if we'll trigger any NPCs to come over," Ning Shu reminded him.
Wu Yi quickly got to work, and he practically ripped out all the electrical wires in the storage room.
"That's enough, let's get out of here." Ning Shu looked at Cheng Chuan, who was on guard duty, and he hadn't said a word, so he guessed that no one had come yet.
"Quick, someone's coming!" Cheng Chuan suddenly exclaimed.
