Two days later.

Yilin was wearing a black robe and a pointed hat.

On the podium, A Deng, a white-bearded man, held a small stick, talked happily, and was full of energy.

A Deng's head was green.

Don't get me wrong.

It's just that the name is green, and the others are not green.

After officially becoming a member of the University of Engineering, on the Yilin [Reputation] panel, the University of Engineering's reputation has also advanced from "neutral" to "friendly".

So A Deng's name is green.

Become a green name friendly NPC.

Yi Lin naturally had another title.

——【College Engineer】.

This title can be advanced.

To advance, you must complete the courses and exams in the College of Engineering in order to advance step by step.

The blackboard is covered with various lines.

"Texture" and "node".

A Deng raised the blackboard hard, for fear that Yi Lin would be abandoned and gave a loud lecture.

"Now, my dear student, listen."

After Yi Lin's identity changed, Old Deng became arrogant and no longer called Yi Lin the "Hisser of the Brave".

Gone are the days when they are regarded as respected by players.

Now Yi Lin is the cute newbie under A Deng, the kind who has no signs.

"I have already explained the theoretical basis to you."

"In the entire engineering, crystal pattern science is the top priority. Only by mastering the 'crystal pattern science' can we create a 'loop' with various functions."

"Note, it's time to ask questions!"

A Deng raised his white eyebrows, and a teasing expression flashed across his face.

"It is known that in the crystal pattern circuit composed of single-core crystal, there are three primary patterns, six secondary patterns, and two advanced patterns. With the premise of the smallest energy consumption, how many 'loops' can we create with less than ten nodes?"

Yilin: "…"

"Two kinds!"

Seeing Yi Lin looking confused, A Deng knocked on the blackboard with a grudge: "There are the 'secondary acceleration circuit' and 'secondary floating circuit'! Don't you understand this? Let's have another question!"

"We must build a 'compound circuit' with three circuit modules with 'secondary defense circuit', 'secondary heating circuit' and 'secondary cooling circuit', can the above-mentioned 'compound circuit' be constructed with a single core and twenty nodes? Please answer."

Yi Lin's eyes lit up.

He seems to understand this question.

Yi Lin quickly flipped through the heavy "Elementary Crystal Patterns", "Big Points of Circuit Construction", and "The Optimal Solution to Node Selection" on the desktop.

Five minutes later.

Yi Lin answered carefully: "It seems...can it be?"

"Wrong!" A Deng knocked on the blackboard hard: "Silly! The secondary heating circuit and the secondary cooling circuit are typical 'conflict circuit', and it cannot be constructed with a single core! Unless you want to explode! This is an entry-level question for young children!"

Dong!

Yi Lin hit the cover of the textbook.

Outside the classroom.

Emperor Wang Tian lay contentedly outside the door. He listened to the roar from inside, and couldn't help but pull his ears down and cover them tightly.

It seems...it's a bit miserable.

“…”

...

"Now I'll give you a practical lesson."

A Deng took out a piece of patterned paper that had been drawn in advance.

Yi Lin carefully identified the pattern, and was a little unsure: "Second heating circuit?"

A Deng nodded in admiration and expressed his gratitude: "You finally got the answer right!"

“…”

A Deng took out another small flask with water inside.

I saw A Deng put a complete small crystal in the "core" position, and then put some crystal debris on the "node".

A simple crystal pattern single loop has been constructed.

Soon, the lines on the paper lit up.

In the complete circuit, the power of crystal flows silently.

Yi Lin looked at it very seriously, her eyes blinking without blinking, and she didn't want to miss any details.

After a few minutes.

The water in the flask began to boil.

No matter how many times I read it, Yi Lin felt that this "engineering" was very magical, which made Yi Lin gradually forget where she was, and it was a game world.

"You're magic..."

"No, this is science! Believe in science! Science and technology are the primary productive forces. You can try it and build the simplest 'secondary heating circuit'."

"Okay!"

Yi Lin was eager to try.

"Loop...node...crystal pattern..."

A Deng used freshly boiling hot water to make a pot of tea and use it for the best use. Waste is shameful.

While tasting cheap black tea, the great engineer A Deng had time to pay attention to Yi Lin's movements.

"Huh? It's very fast! Ah? Wait, don't put it there! This is a blow-up-"

boom!

Rolling smoke poured out of the classroom.

Yi Lin walked out of the thick smoke and silently took out the communication crystal.

"Uh, is the medical team? An accidental explosion occurred in the C-101 laboratory on the 43rd floor. Deng...the big engineer fainted. Hum? Which big engineer do you think? I think...Albus Perciva Woolflick Brian Dumbledore. Well, you should still be alive, hurry up, don't rush."

This time, Yi Lin finally skillfully called out A Deng's full name.

A Deng, who was in a coma, expressed his gratitude.

...

...

One month later.

54th floor Library of the University of Engineering College.

Area C.

The title above Yi Lin also successfully advanced from [College Engineer] to [Intermediate Engineer].

The explosion accident a month ago is still vivid in my mind.

A Deng never expected that this "extremely dangerous student" who created explosion accidents could have completed courses from "student engineer" in just one month, and passed the assessments one after another, and obtained the title of "intermediate engineer" without any water.

You were so awesome at the beginning, wouldn’t I have to be blown up?
