Wren must admit that people are different.

For an ordinary man like him, teaching an apprentice feels like teaching a combination of Edison, Tesla, and Newton.

He felt that he was more like some kind of tutor at the University of Crooked Fruit Pheasant, and he threw a title a few times, and then the students tossed it out on their own, and finally he signed the name of 'tutor' and finished it.

Anyway, the school is pheasant-level, and if the students pay the tuition, whether they will learn or not, and whether they will recognize their academic qualifications in the future, then God knows.

Probably this is the legendary [Ruxue].

Learned?

Learned...... Right!?

Teach Downs "Sliding Friction", this thing has realized a 4-ring spell magic [Sticky Magic Ball], which can summon a snot-like sticky hydraulic pressure to restrain slow-reacting enemies and make them unable to move.

Teach thermodynamics and learn a bunch of fire spells.

If all of this is related, and Wren can imagine what Downs has learned in general, the most recent pinnacle of abstraction is teaching him "Atmospheric Pressure."

"Generally speaking, the higher the temperature, the faster the atmospheric expansion and the lower the air pressure, regardless of other factors such as power......"

Teaching is teaching, after Wren taught, Downs realized something, that is, to open the blind box.

A few minutes later, Wren seemed to see an illusory light bulb light on the door of Downs' head.

"Master, I've come to my senses!"

"You're enlightened again?"

"That's right! Where it's too high, what pressure is low, can I put pressure on myself, let me put pressure on me, and then stand firm anywhere? ”

Downs's description was so abstract that Wren couldn't keep up with the pace of his apprentice's thinking for a while.

It doesn't matter if Wren doesn't understand, the system understands: "You try." ”

Anyway, it won't be the Master who will die if you try!

Downs stood on the spot on the trunk of a large tree, the kind of person who was completely parallel to the ground, 90 degrees to the earth, straight towards the canopy.

[Congratulations to the host, your disciple Dons has comprehended the level 4 transformation magic (fictional gravity), which allows the caster to walk on any solid and 'fall' in a specific direction according to his 'will'.] 】

Seeing this, Wren bared his teeth: This is cool, let's open it, it's interesting.

For a while, Wren thought that his evil apprentice would go all the way to the legendary mage.

Until this day, Wren taught series and parallel circuits.

Wren wrote the most basic theorem on the blackboard:

Concatenation:

(1) There is only one path for the current.

(2) The current of the series circuit is equal everywhere.

(3) The total voltage of the series circuit is equal to the sum of the voltages at all places.

(4) The equivalent resistance of the series resistors is equal to the sum of the resistors.

Parallel connection:

(1) The circuit has several paths.

(2) The voltage is equal everywhere in the parallel circuit;

After writing, Wren put down the chalk, clapped his hands, and ran off to fishing.

Who knows how ten minutes have passed.

Twenty.

Thirty......

One hour.

This time, Wren didn't wait for the sentence 'Master, I understand', but instead he saw a face that was depressed, puzzled, and even a little nervous.

"Master, I, I, I really didn't expect anything. Am I too stupid. ”

Wren was stunned for a moment, and the sentence 'You are the worst class of students I have ever led' came to his lips, and it became: "A little stupid, but don't worry, at least you are not the kind of incorrigible stupid." ”

Young people just have a momentum, but one day they suddenly get tired, tired, and can't impulse?

If Wren still holds the initial mentality that the apprentice will die and something will happen sooner or later, and he must change it as soon as possible, it is estimated that he will breathe a sigh of relief in his heart, and then decisively sell the apprentice.

But unconsciously, the two have been together for three months.

People are not plants.

Not to mention such a big living person, even if it is an ordinary cat or dog, how can it have feelings after three months.

"Master, I, I can still be saved?"

Wren reached over and flicked Downs' brain with one finger.

"Ahh

"If you can be saved, it depends on whether you are really obedient and correct your mentality."

"I will be obedient!" Downston squatted and sat up, the unique kneeling posture of this world, and it was much more standard. The word "well-behaved" is revealed all over the body.

"Learning is like that, a lot of times the early stage is very fast and smooth, and you can learn something new and gain something new every day. But one day, you will suddenly find that you can't move to the next level. ”

"Ahh Downs let out a soft scream.

Wren raised the knock-off Coke glass bottle in his hand: "This is the [bottleneck]!" ”

"Bottleneck?" Downs's voice was almost murmuring.

Seeing the apprentice in a difficult situation, Wren suddenly felt like a teacher. In the past, a law of physics was taught, and this thing comprehended another magic. As a teacher, Wren really has no sense of accomplishment.

Over time, people are numb.

If it weren't for the fact that the bonuses offered by this shit apprentice were too fragrant, Wren would have shouted something 'tired, destroy'.

Now I finally have the feeling of guiding the lost lambs to the 1024 website, ahhh

"That's right! Bottleneck. When you feel stuck, you need to find really good books, go through them, and then accumulate them. Of course, not all books are read. In Minecraft, there is [One-click Generate Small Essays], which can write a document of 100,000 words in a second. There is also [Quantum Reading], which can read a book in eight seconds. There are even more hateful readers who spray at the authors who write novels, 'You can't write as fast as I can read'......"

As Wren said this, Downs' eyes widened, and his mouth was wide enough to fit an apple in.

These outrageous things are typical of the [Arabian Nights] in Downs's worldview.

Wren complained by the way: "But this kind of thing has no soul." You need to read the same type of books, no, even the occasional book of music and art, you can touch the ......"

What Wren originally wanted to say was that those online texts made by the automatic codeword program couldn't be read at all, and then he said a lot of it very kindly, who knows, when he heard the word 'soul', Downs filtered out Wren's later words, and his mind suddenly became active.

"[Soul]!?"

"That's right! Soul. When he saw the good apprentice's eyes lit up, Wren suddenly had an ominous premonition.

A certain master was a little scared: The soul in my mouth, are you sure that it is the same thing as me?

Soul, literally.

I saw Downs shouting, "Master! I'm enlightened again! ”

No, wait, it's not scientific, you're enlightened again?

Wren's eyes widened as he watched as the good apprentice suddenly stretched out his left hand and grabbed it in midair. A string of wind elementals seemed to scream in amazement as it was pulled down from the void by someone abruptly, and let out an angry roar.

Downs didn't care, his arms were open, and it felt like opening a tome dictionary, or stretching out a large net.

At a glance, this should be a level 3 plastic energy magic [lightning beam].

Wren immediately realized that something was wrong. This 'beam' of lightning is too wide. And not one, but three, no, a total of five.

Wren was stunned to find that when five swaying lightning beams were placed side by side, floating in mid-air, wouldn't this scene be like ......

Downs puffed out his chest proudly: "Thank you, Master, for your advice!" It turns out that the key to making a 'parallel circuit' is to inject a [soul] of the wind element into each circuit! ”

At the same time that a master's mind suffered an outrageous blow, the system prompt came: [Congratulations to the host's apprentice for comprehending the super magic specialty (spell expansion), which can increase the area of influence of burst, diffuse, straight or diffuse spells. All values of spells are doubled. This super-magic specialty is permanently shared with Master......]

Master: Grass (a plant)!

Let's just say it's not parallel.
