Two days later.
Irin wore a black robe and a pointed hat.
On the podium, the white-bearded Ah Deng held a small stick and spoke with confidence and vigor.
The top of Ah Deng's head was green.
Don't get me wrong.
Only his name was green, but nothing else was green.
After officially becoming a member of the Engineering College, Irin's [Reputation] Panel showed that his Reputation with the Engineering College had advanced from "Neutral" to "Friendly".
Therefore, Ah Deng's name was green.
He became a friendly NPC with a green name.
Irin also gained a new title.
[Student Engineer].
This title could be advanced.
If one wanted to advance, they had to honestly complete the courses and exams in the Engineering College. Only then could they advance step by step.
All kinds of lines were drawn on the blackboard.
"Lines" and "Nodes".
Ah Deng raised the blackboard with all his might, afraid that Irin would be distracted and lecture loudly.
"Now, my dear student, listen carefully."
After Irin's identity changed, Ah Deng became arrogant and no longer called Irin "Your Excellency Hero".
The days of being respected as a player were gone forever.
The current Irin was a newbie student under Ah Deng, the kind that had no reputation.
"I have finished explaining the theoretical foundation to you.
"In the entire field of engineering, the study of crystal patterns is the most important. Only by mastering the study of crystal patterns can one create circuits with all kinds of functions.
"Pay attention, it is time for questions!"
Ah Deng raised his white eyebrows, and a teasing expression flashed across his face.
"Among the crystal pattern circuits that are made of single-core crystals, there are three primary patterns, six secondary patterns, and two advanced patterns. Under the premise that the energy consumption is minimal, how many circuits can we create with less than ten nodes? "
Irin: "…"
"Two!"
Seeing Irin's dumbfounded expression, Ah Deng knocked on the blackboard in exasperation. "They are the secondary acceleration circuit and the secondary levitation circuit! You don't even know this? One more question! "
"In order to construct a 'composite circuit' that has three circuit modules, namely, a 'secondary defense circuit', a 'secondary heating circuit', and a 'secondary cooling circuit', is it possible to complete the construction of the above 'composite circuit' with a single core and twenty nodes? Please answer. "
Irin's eyes lit up.
He seemed to understand this problem.
Irin hurriedly flipped through the thick [Basic Crystal Pattern Study], [Key Points of Circuit Construction], and [Optimal Solution for Node Selection] on the table.
Five minutes later.
Irin replied cautiously, "It seems … possible?"
"Wrong!" Ah Deng knocked hard on the blackboard. "Stupid! The secondary heating circuit and the secondary cooling circuit were typical 'conflicting circuits'. It was impossible to construct them with a single core! Unless you want to explode! This is an entry-level question for children! "
Dong!
Irin hit her head on the cover of the textbook.
Outside the classroom.
Celestial Emperor Wang lay outside the door contentedly as he listened to the roars coming from inside. He couldn't help but pull his ears down and cover them tightly.
It seemed … a little tragic.
"…"
…
"Now, I'll give you a practical lesson."
Ah Deng took out a piece of paper with a pattern drawn in advance.
Irin carefully identified the pattern and was somewhat uncertain. "Secondary heating circuit?"
Ah Deng nodded in appreciation, his expression gratified. "You finally got it right for once!"
"…"
Ah Deng took out a small flask with water inside.
Ah Deng placed a complete small crystal at the 'core' position and then placed some crystal fragments at the 'node'.
A simple single circuit of crystal patterns was constructed.
Soon, the patterns on the paper lit up.
In the complete circuit, the power of the crystal silently flowed.
Irin looked at it very seriously, his eyes not blinking. He didn't want to miss a single detail.
Several minutes later.
The water in the flask began to boil.
No matter how many times he looked at it, Irin felt that this' engineering 'was very magical. It made Irin gradually forget that he was in a game world.
"This is magic, right …?"
"Nonsense, this is science! You must believe in science! Science and technology are the primary productive forces. Give it a try. Construct the simplest 'secondary heating circuit'. "
"Okay!"
Irin was eager to give it a try.
"Circuit … Node … Crystal pattern …"
Ah Deng used the boiling water to make a pot of tea. He was making the best use of everything. It was shameful to waste.
While tasting the cheap black tea, Ah Deng finally had the time to pay attention to Irin's movements.
"Eh? You're very fast! Ah, here? Wait, don't put it there! This is exploding — "
Boom!
Thick smoke surged out of the classroom.
Irin walked out of the thick smoke and silently took out the communication crystal.
"Uh, medical team? There was an accidental explosion in laboratory C-101 on the 43rd floor. Deng … the great engineer fainted. Hmm? Which great engineer are you talking about? Let me think, it's … Albus Percival Wulfric Bryan Dumbledore. Hmm, he should still be alive. Hurry up, don't dawdle. "
This time, Irin finally called out Ah Deng's full name.
The unconscious Ah Deng was very pleased.
…
…
One month later.
The 54th floor of the Great Engineering College library.
Area C.
The title above Irin's head had also successfully advanced from [Student Engineer] to [Intermediate Engineer].
The explosion accident a month ago was still vivid in Ah Deng's mind.
Ah Deng had never expected that this "Extremely Dangerous Student", who had created one explosion after another, would actually be able to complete one course after another from the "Student Engineer" in just one month. He passed one assessment after another and obtained the title of "Intermediate Engineer" without any tricks.
If you were so awesome back then, I wouldn't have been blown up, right?
…
"Intermediate Crystal Pattern Study Guide".
"Analysis of the Choice of Circuits with Multiple Cores and Single Cores".
"Advanced Node Construction Guide".
"Defensive Circuits, Intermediate".
"Detailed Explanation of the Construction of Conflicting Circuits".
"Floating Circuits, Advanced".
"Lightning Circuits, Elementary".
"Crystal Types Encyclopedia".
"On the Idea of Using Conflicting Circuits to Create Explosions".
Eh?
"On the Self-cultivation of Great Engineers"?
Why didn't I know that great engineers had self-cultivation?
Irin looked at the signature.
"By Albus Percival Wulfric Bryan Dumbledore."
Then it's fine.
Irin ignored this useless book with a blank expression.
"It seems that I've read almost all of them."
Irin's fingertips brushed across the covers of the books one by one. They were dull and tasteless.
He had read all of these.
Although there were many contents that he could not fully understand, Irin used his terrifying memory to forcibly memorize these contents and slowly digest them afterward.
Irin raised his head and looked at the endless bookshelf in front of him. He was speechless.
It was fine if a good turn-based RPG online game used this method to convey knowledge. But why couldn't they tidy up the bookshelf a little? There were more than 50% of the books on the bookshelf. Although the authors were different, the contents were more or less the same. Irin even sometimes read several textbooks of the same type, and there were even identical sentences in them.
After Irin blew up Ah Deng a few times, Ah Deng was also scared. He directly gave Irin the authority of the 54th floor of the library and became a hands-off shopkeeper.
He also glorified it by saying that true geniuses relied on self-study.
"Eh? This book seems to be a little interesting. "
"Detailed Explanation of Crystal Patterns, Nodes, and Cores in Super Large Composite Circuits."
There were a total of three libraries in this huge engineering tower.
Ah Deng treated him well. The books in the 54th floor of the library were of the highest level. Normal students could not enter, and it was not even open to "exchange students."
In the huge library, there were no other students besides Irin. It was so quiet that only the sound of Irin flipping the pages of the books could be heard.
"This game is too interesting. I'm really curious. Is this knowledge made up out of thin air? The principles are explained clearly and logically. Once I really learn it, I can't help but be engrossed in it and not be in the mood to level up. In that case, I'm really an incompetent 'Elite Player.' "
For an entire month, other than looking for Ah Deng to complete the corresponding assessment and having a reasonable rest schedule, Irin spent most of his time in the library.
Perhaps even Ah Deng couldn't imagine how many books Yi Lin had read in the past month and how much knowledge she had grasped about the study of crystal patterns.
Irin even took some time to skim through "The Mechanical Structure of Floating Airships."
Unfortunately, Irin was not very interested and did not put too much thought into it.
"The crystal in this game world is equivalent to a pure 'energy source.' Crystal Pattern Studies can use this' energy source 'in a specific way and exert a specific effect. Whether it is the thickness of the patterns, the distribution of nodes, or the number of cores, they all determine the extent to which this' energy source 'can be exerted. "
"Moreover, this energy source is a one-time, non-renewable resource. No wonder they were so anxious after the so-called 'crystal mine' dried up. Everything in this game world is inseparable from the 'crystal.' Once the crystal is lost, many facilities in this world will not be able to operate. Heh, the game setting should be like this. "
But, was it really so?
Irin closed his eyes.
For the past month, Irin had asked himself the same question countless times.
Was this really just a simple game world?
Whether it was the interaction with the NPCs or the complex, mysterious, and ridiculously complete crystal pattern study system, it was hard for Irin to believe that he was currently in a simple game world.
It was hard for him to imagine who had the ability to create such a huge technological system.
Irin even had a feeling that this strange technology could be used even in the real world.
Of course, the premise was that there was an energy source like the 'crystal' in the real world.
"But the essence of the crystal is only a type of 'high-purity energy.' Can it be replaced by other energy sources?"
Irin flipped through the book while multitasking. Many thoughts flashed through his mind.
An hour later.
Irin memorized another book.
He silently closed "Detailed Explanation of the Arrangement of Crystal Patterns, Nodes, and Cores in Super Large-scale Compound Circuits." While there was still time, he continued to stand up and walk back and forth among the neat bookshelves to see if he could find any interesting books.
"Hmm? This is? "
Irin's gaze swept across the corner of the bookshelf.
He saw that there was an ancient book without any words on the cover. This ancient book was made of the skin of some kind of demon. It looked very old, and there were many cracks on the demon's skin. He flipped open the title page, and the inside pages were already yellowed. Obviously, this book had gone through a lot of vicissitudes.
"It's just a game. Is there a need to spend so much effort on such details?"
Irin smiled gently and looked at the three words on the title page.
— "World History."
"Oh?"
With curiosity, Irin patted the dust inside, and then, with the soft light of the crystal lamp, he simply sat on the ground and read.
After an unknown period of time.
Irin sat up straight.
The smile on his face gradually disappeared and was replaced by a solemn expression.
"Ding!"
At this moment.
[Current Main Mission Objective: Find the source of the apocalyptic crisis. Objective completed!]
[Received EXP + 18000.]
[Received Gold Coins + 12000 G.]
[Main Mission has been updated!]
[Current Main Mission: The Hero's Mission.]
[Current Mission Objective: Find more clues about the 'Evil God.']
[Mission Difficulty: A +]
[Mission Time Limit: None.]
[Mission Reward: EXP + 25000.]
Immediately after.
A golden light rushed straight to the top of Irin's head.
[Congratulations!]
[Level up to Level 36!]
[Received 'God's Gift Point'!]
After being stuck at the level for a whole month, he finally leveled up under this wave of golden light.
But at this moment, Irin had no time to appreciate the joy brought by leveling up. He expressionlessly closed the "World History" in his hands and hurried out of the 54th floor of the library.
