People in Mondstadt, starting to develop black technology

She would never feel safe without the bomb.

"The only thing left is the electrical crystal."

Shen Qin went to the Adventurer's Association again.

Electric crystal is a very special alchemical material with very few uses and is very rare in the wild. Therefore, if you want to obtain it, you can only obtain it by issuing a temporary commission in the Adventurer's Association.

As for how to pay the commission...I can only borrow Mora from Klee temporarily!

Then he met Kaia there again.

"Ah, Shen Qin!" Kaiya waved his hands repeatedly, looking at the speechless Shen Qin with a helpless look, "Sorry, sorry, this is really just a coincidence."

Does that mean the previous two times weren't coincidences?

Kaiya heard the conversation between him and Catherine and asked curiously, "You want electric crystal? This kind of thing is not easy to find. It usually takes an adventurer two or three days to go out, and it is not certain to be found."

"So troublesome?" Shen Qin frowned.

The electric crystal is the energy source of the flying skateboard. All other components must be developed with it as the core. Before obtaining it, research and development work cannot be carried out at all.

"Are you in a hurry to use it?" Seeing Shen Qin's reaction, he continued to ask.

Shen Qin answered truthfully: "It's very urgent. It would be best if I could get it now."

"I see..." Kaiya stroked his chin and thought for a few seconds. Suddenly he thought of something and a playful smile appeared on his face. "I know someone who may have the electric crystal. How about I take you to see her?"

Shen Qin looked at him strangely, not understanding why he would take the initiative to help when he was always targeting him.

"Don't look at me with such suspicion. Are you worried that I have ulterior motives? You are worrying too much. I am also a member of the Knights. As long as guests like you need help, our Knights will try our best to provide assistance. Besides, you have proved yourself this morning."

Shen Qin hesitated for a while, and finally agreed to go with him to meet the man.

"Oh, by the way, that person has a bad temper and a weird personality. Try not to speak later. If you say something offensive to her, both of us will be in trouble." Kaia said solemnly.

That person, can't be...

Shen Qin had a bad feeling.

When Kaeya brought him to the library of the Knights of Favonius, Shen Qin covered his forehead in pain. As expected...

The purple witch lazily lay on the recliner, the extremely fabric-saving wizard robe fit her skin, drawing a series of attractive curves. A book was suspended in front of her, controlled by her elemental power, and she didn't even need to lift her hands to turn the pages.

Lisa noticed the two people coming straight towards her, but she just glanced at them without even trying to stand up: "It's Kaia and the strange little guest. What do you want from me?"

I am already a useless person.JPG.

"Lisa, this alchemist needs electrical crystals. I thought you might have some here, so I brought him here."

"Oh? Are you the new alchemist?" Lisa closed the book, stood up, walked to Shen Qin, bent down and looked closely into his eyes.

The distance between their noses was no more than ten centimeters. Shen Qin could even sense her breath and the faint fragrance on her body. What was even more terrible was that she was wearing a low-cut dress, and the posture she was bending over at the moment...

Shen Qin closed his eyes and took a few steps back. He could already feel a tiny electric current surging in the air. If he did something impolite, he might be carried out of the library horizontally the next moment.

"Haha, you're a good kid." Lisa smiled and stood up straight. "I can give you the electric crystal for free, but you have to do me a small favor."

After hearing her voice fade away, Shen Qin opened his eyes and asked, "What can I do for you?"

"Alas, I thought being a librarian was an easy job, but I didn't expect there would be so much to do every day. I have to register when books are borrowed and returned, and put the books that customers stuffed in after reading back to their original places. I have to personally go to the homes of some people who don't return books on time to urge them to do so. Sometimes I really want to quit this job."

Kaia smiled and said, "Compared to the others in our Knights, you have it pretty easy. At least you don't have to run out of the city."

"Going on adventures occasionally may be a way to spice up life." Lisa sighed and looked at Shen Qin. "Here's the thing. If you can come to the library to help me for a few days and let me have a good rest, the electric crystal will be yours."

[A temporary task was detected: design a book management system for the library. ]

[Unlock the following blueprints/knowledge: Library Terminal, Robotics Principles, Teyvat Coding Language. ]

[Task Reward: Eligibility to draw a random blueprint.]

Shen Qin absorbed a vast amount of knowledge in his mind, but in the eyes of Kaiya and the others, he just stood there and suddenly became dazed.

"Hey, little guest, wake up, are you bewitched by your sister?"

Shen Qin came back to his senses and said to Lisa excitedly, "Miss Lisa, I promise you that I can design a book management system for the library, so that whether it is borrowing and returning books or sorting and classifying books, you don't need to do it yourself, just operate on the system."

"Library management system? What is that?" Lisa asked with interest.

Kaiya also became interested and decided not to leave. He wanted to know what Shen Qin was talking about.

"That's right. This system can record all the books in the library, and borrowers can also register on their own through the terminal that carries this system. You see..."

Shen Qin came to a flat table and drew a square on it with his fingers.

"There is a screen on the terminal that can display pictures and text. Borrowers can register the borrowing and returning of books on the terminal by clicking on the pictures and text on the screen with their fingers. You just need to watch from the side."

“If you want to organize books, as long as you have entered the correct location of the books in advance, the system will automatically put them back in place, and you only need to operate with your fingers on the screen!”

"It sounds interesting! Especially the system and terminal you mentioned. I feel that it is somewhat similar to Xumi's void and void terminal... Am I right?"

Lisa is worthy of being a genius witch from the Sumeru School. She immediately found something similar.

"Well, there are some differences, but not much." Shen Qin confirmed.

"What about the organization of books? If the system is just an illusory existence, how can it control books and elemental forces that exist as entities?"

Shen Qin stroked his chin and thought: "Maybe I can design a kind of, um... mechanical floating spirits, which will also be connected to the system and cooperate with the system to do some work that requires a physical body."

"What a genius idea!" Lisa clapped softly and looked at Shen Qin in surprise. Kaiya was also very surprised. Although he couldn't understand how to do what Shen Qin said, just imagining that picture made him feel a powerful shock.

If this system is also used in the daily work of the Knights, will it reduce a lot of workload... he thought to himself.

Shen Qin thought for a moment and continued, "If I have enough time, I can even refer to the Void and develop a personal terminal so that everyone can read books through the terminal anytime and anywhere, without having to go to the library to borrow physical books. However, that requires building a network similar to the Void to connect all the terminals, which is too difficult to achieve."

"Are you really... not a disciple of some old monster who has never appeared in the world in the Xumi Sect?" Lisa was shocked by his thinking.

In Xumi, countless people use the void to gain knowledge, but no one has ever thought of imitating the void to create another "void".

"Shen Qin, if you can really make this...library management system, our Knights of Favonius will give you our greatest support." Kaeya's expression became serious.

Shen Qin grinned: "Then please give me the electric crystal first."

With the promise made by Kaeya on behalf of the Knights of Favonius, Shen Qin happily returned to the alchemy workshop holding the electric crystal. He promised to create a prototype of a library management system in three days.

After he left, Kaiya secretly discussed some things with Lisa. During the discussion, she mentioned her evaluation of Shen Qin. Lisa smiled and said, "Through his eyes, I can see that he has some secrets, but he is still a good boy and a talented alchemist."

Chapter 5 Library Management System

After the Knights of Favonius delivered the materials for the library management system to the alchemy workshop, Shen Qin entered into seclusion mode.

Klee came to play with him, and after learning that he was busy with alchemy, although she felt a little disappointed, she still behaved well and did not disturb him.

"Klee doesn't like being disturbed when she's making bombs." The little guy carefully closed the door of the alchemy workshop, muttering.

After "driving" Klee away, Shen Qin always felt a little guilty, but as the price of obtaining the electric crystal, he had to hurry up to develop the library management system and then make a flying skateboard.

The entire system is mainly divided into two parts: hardware and software. The hardware is a complete terminal including the screen, and the software requires a system to be written using a coding language based on the terminal.

If all Earth technology was used, even if Shen Qin mastered all the technologies, he would not be able to develop a usable terminal in a short period of time. However, the alchemy of Teyvat includes both technology and mysticism, and the mysticism side is not very reasonable.

According to the drawings given by the system, Shen Qin put five crystal cores into the grinder and ground them into powder for later use. Then he mixed the small lamp grass with distilled water in a ratio of one to ten, and heated it at a temperature of one hundred degrees for one hour.

While waiting for the lamp grass solution to heat up, he ground the amber, night stone, and crystallized bone marrow into powder in a ratio of three to one to four, and poured it into two kilograms of melted tin.

After stirring the molten iron thoroughly, he poured it into a mold that was 20 centimeters long and 30 centimeters wide.

At this time, the small lamp grass solution had been heated for an hour. He poured the previously ground crystal cores into the solution, and the solution actually emitted a faint white light.

That's it! The solution should glow white, which means it's working.

He stopped heating and allowed the solution to cool naturally.

After the molten iron solidified and the temperature dropped, Shen Qin took out the thin piece of light gray alloy that looked like a tablet computer without a screen from the mold, and then polished its surface until it was smooth.

Next comes the most important step.

Shen Qin put on a ten-fold head-mounted microscope, operated a robotic arm, and used a pen as thick as a needle to apply the lamp wick solution little by little on the alloy plate.

Coming from Earth, he never thought that one day he would be drawing pixels by hand.

(The subsequent development process will not be described in detail.)

Shen Qin devoted his whole body and soul to the work. When the last pixel was completed, he finally breathed a sigh of relief and collapsed on the chair as if all the strength in his body had been drained away. His eyes were sore and his hands and feet were weak.

What time is it now? The light outside the window seems to have dimmed.

Shen Qin looked at the clock hanging on the wall and realized that it was not evening yet, but five in the morning.

Forget it, let’s go to sleep first.

He dragged his tired body towards the bedroom, only to find a dinner on the table next to him with a small note next to it.

"Brother Shen Qin, rest early after you're done with your work. It's not good to tire yourself out, and Ke Li will be sad too."

Shen Qin felt a warm feeling in his heart. He folded the note neatly, put it in his shirt pocket, and then wolfed down his dinner.

Before going to bed, he took the finished terminal back to the bedroom.

Well, I’m mainly worried that Klee might accidentally break it while I’m sleeping.

Shen Qin woke up to a strong fragrance. When he opened his eyes, he saw Xiao Keli sitting beside the bed, eating wild mushroom and chicken skewers with relish.

Ke Li heard the noise, turned around and saw that he had woken up, and a happy smile immediately appeared on her face: "Oh, Brother Shen Qin, you finally woke up! If you don't wake up, Ke Li will eat your dinner!"

"Dinner? Keri, did I sleep all day?"

"Yes, Kelly thought that the traveler brother was sick, so she asked Sister Barbara to come and see him. Kelly was so worried." She patted her chest, looking like she was still frightened.

Shen Qin smiled and said, "I was wrong, I was wrong. I shouldn't have made Ke Li worry."

He shared his dinner with her and chatted with her for a while. After she returned to the Knights, he sat back at the workbench. After the terminal was completed, he had not yet taken a close look at the finished product.

The terminal looks like a light gray tablet weighing four pounds, with the screen-to-body ratio on the front being as high as four-fifths.

As for its charging method... Shen Qin placed a piece of electric crystal next to it, and a thin arc connected the two. The terminal screen lit up immediately, but it had not yet been written into the system, so it could only emit white light.

Shen Qin spent three hours writing a super simplified version of the library management system into the terminal. When the colorful system interface slid smoothly under his fingers, he felt a great sense of accomplishment, although all this knowledge was given by the system.

If you ask why simply combining materials together can achieve functions that can only be achieved by combining many technological crystals on the earth.

Magical Teyvat alchemy, boy.

Early the next morning, Shen Qin brought his terminal to the library to find Lisa.

She was obviously startled: "Oh! You said you've done it? Little cutie, don't lie to your sister!"

"Ms. Lisa, please look."

Shen Qin placed the terminal flat on the table, put on insulating gloves, and approached it with an electric crystal. With a flash of electric arc, the terminal screen lit up, and the white silhouette of Dudu Ke appeared, and then entered the system's main page.

When designing the system interface, Shen Qin adopted an overall realistic style, so the homepage shows a scene of a library counter.

Shen Qin put the electric crystal back into his backpack: "It runs on electricity, that is, the energy of the lightning element. The electricity can be stored inside it. Both starting and charging require electric crystals. Of course, you can also directly manipulate the lightning element to replace the electric crystal."

"The terminal is very simple to control. Just click and slide your fingers on the screen." Shen Qin's finger slid, and the scene on the homepage also slid along with his finger.

"How, how is this possible? The picture can actually move with the fingers!" Lisa expressed her incomprehension. She had come into contact with screens when she was in the Ministry of Education, but they could only display content, and operation had to be achieved through joysticks and buttons.

Shen Qin did not answer her question, but continued his explanation: "Currently the system only has two simplest functions, inventory and borrowing."

"Click on the bookshelf to enter the inventory function, and click on the counter to enter the borrowing function." He clicked on the bookshelf on the screen, and immediately a smooth book opening animation played, and then three sub-options appeared on the opened book page, namely "Inventory Update", "In and Out of Warehouse" and "Inventory Sorting".

"Inventory update is easy to understand. After the first click, it will automatically scan all the books in the library and add them to the inventory." Shen Qin explained while operating.

When the screen displayed "Scanning", Lisa keenly felt the fluctuation of the thunder element in the air. When she looked at the screen again, she found that the scan had been completed, and a dense list of book titles was displayed on it.

"Well, the scan results show that there are a total of 4,683 books in the library. Does this number make sense?" Shen Qin looked up at Lisa.

"No, there are 4,700 books in total..." Lisa shook her head to deny it, but then she widened her eyes and said in surprise, "There are still 17 books on loan, which makes the total just right!"

Then she moved her fingers slightly, manipulated several thick books to fall on the table, and pointed at them and asked Shen Qin: "You mean, all the book inventory recorded here was recorded by this terminal in just a few seconds?"

"Yes." Shen Qin nodded affirmatively.

"How, how is this possible?!"

After taking a quick look at the screen, Lisa...sister lost her composure rarely. She took several deep breaths before calming down her emotions. However, the ups and downs of her chest made Shen Qin feel a little dizzy.

"My little cutie, you are such a genius." She praised Shen Qin seriously.
