Between heaven and earth, the wind and clouds surged, thunder and lightning flashed.

Downs couldn't hear anything.

He entered a typical realm of forgetting the self and the self.

In his mind, it was full of shocking images that Master had just demonstrated, and then he used his imagination to imagine what it would be like to shatter the stars.

I'm sorry!

As the heir of a declining knight family, he really couldn't imagine it, he could only think of what it would be like when he expanded the situation in front of him a hundred times and shattered the mountains.

Even so, it was enough to shock him so much that he couldn't control himself, and even forgot to breathe for a while.

A feeling that he couldn't do anything but bow and worship filled his whole heart - what a powerful master I worshipped!?

Here, Wren seemed to be waiting for his disciple to adjust his breathing and come back to his senses.

In fact, he himself was scared!

Thunder strikes something, and the lightning is led away by the lightning rod, which is very scientific.

Coincidentally, as soon as he raised his hand, the thunder and lightning fell, which is very unscientific.

Before the crossing, there were 50,000 thunderstorms per day across the globe, with an average of 4,000 lightning strikes per second.

But why did it just fall in front of his Wren's eyes, it was like ......

Suddenly, Wren found the answer in the system on the retina that had been pretending to be dead for a long time.

A large number of green votes are displayed as follows: [In view of the fact that the first apprentice of the host has already started, the physical experiment demonstration system is hereby turned on......]

[This demonstration system is only for physics teaching purposes and will not cause any physical harm to people.] The energy required for the demonstration of the system is taken from the (teaching points) of the apprentices! 】

Wren found that the [Lightning Rod Principle Demonstration] item had turned gray.

The most annoying thing is that there is a note at the back: [The technology is too backward and can be displayed].

If you look closely, you can see that the physical experiments that already exist on the earth and are well known to Wren can be demonstrated through this system.

Here's the point:

[This system pays attention to convincing people with (reason), when the goal is not (reason), the master has the right to talk to him by physical means! 】

Wait a minute!

In the middle of the picture of the Mao system is an axe made of the Chinese character "Li" with a terrifying thunderbolt?

If you play like this, I can still convince people with [virtue]!

The only thing that made Wren a little tangled was the [Word Axe], which also had to be charged.

I don't want to do that for now.

Recovering from the shock, Downs habitually bowed deeply: "Please Master start teaching!" ”

Since this broken system is like this, let's teach it.

To be honest, Wren didn't expect to teach anything at all, and he always felt that what Downs achieved in the future in magic probably had little to do with him.

Quite casually, Wren found a so-called blackboard.

It was the only remaining wall of a dilapidated house, I don't know if it was marble or something, anyway, it was struck by lightning, the whole wall was scorched black, but the wall was extremely smooth, very suitable for writing and drawing.

With a little white ash, Wren began to teach on the 'blackboard', and according to the system, he gave him language proficiency and wrote Kaos script.

"Voltage, also known as potential difference or potential difference, is a physical quantity that measures the difference in energy between a unit charge in an electrostatic field due to different potentials. The magnitude of the voltage from one point to another is equal to the work done by the unit positive charge to move from one point to another due to the action of the electric field force, and the direction of the voltage is specified as the direction from the high potential to the low potential. ”

By the way, Downs is definitely not illiterate.

Before an aristocratic apprentice becomes a knight, he needs to be trained and educated in religion, morality, cultural knowledge, and military affairs.

For Downs, who was not a superior nobleman, reading and literacy was also a basic requirement.

It's just that these knowledge that even the science and engineering dogs on Earth need to memorize by rote is a book of heaven for Downs.

It's like when the teacher says 1+1=2 in class, and when you look down and take a note, you see calculus on a blackboard full of calculus......

Lore!

But Wren was a little ruthless, and he tapped his knuckles the 'blackboard': "Every noun and every word here is the key point and needs to be tested." If you can't even understand this level, you are not qualified to delve into [science]! ”

Wren was deliberately making things difficult for Downs.

Seriously, it's not that he doesn't want to take in apprentices, it's that he's afraid.

Learn bullshit electromagnetic induction, dare to touch the electric door in the middle of the night, but if he finds out a little later, he may not be able to see Downs in front of him, but Jiao 'Tang' Macchiato.

Wren is not afraid of other people's death, just begs not to die in front of himself.

The price of Lao Tzu's psychological shadow expansion area, you Tang Si can't afford it!

Since this is an apprenticeship system, who is accepted as an apprentice is not accepted? Change to a normal point and slowly save points, isn't this fragrant?

Anyway, Downs already has the most rudimentary thunder and lightning magic (tricks), and Wren prides himself on being a teacher who is not a cheater.

Be bold, it is not impossible to consider dropping the tuition fee that you accept and only half of the tuition fee will be refunded.

When Tang Si put on a straight face and posed as a strict teacher, but in fact thought about making money, the 'high apprentice' on the opposite side fell into the biggest crisis in his life.

Downs broke out in a cold sweat, to the point of sweating.

He had imagined that such a powerful teacher Wren must be very strict and difficult to teach, but he really never thought that [science] would be difficult to do this.

What to do?

Urgent!

No! Wait a minute.

How did I forget again?

Why didn't Master teach elsewhere, but on this blackened wall scorched by lightning?

Master, when did he remind me that he didn't put it in his words?

Master's words can never be understood in a complete sentence! It must be taken apart word by word.

'Every noun, every word is the point'...... I get it! No wonder I can't understand these theories and formulas at all, it turns out that I want to take them apart and look at them one by one!

Downs's eyes were bright, and the divine light that burst out was comparable to Ambilight.

When he behaved like this, Wren suddenly had a bad feeling in his heart: Isn't it? How can I have this kid's ominous premonition that he wants to be crooked?

Once is already a big luck, can you come twice?

As everyone knows, in Downs's eyes, the formulas and theories have all changed.

They have become little people, these little people are not neatly arranged, but they definitely contain a regular line, as if they are dancing with their teeth and claws.

"They are the truth of the world. That is, the spell of thunder and lightning magic. The spells are combined into a legendary circle, and if I understand it this way, I know—" At first, there was an almost inaudible mutter, and then Downs spoke louder and louder, and he heard a certain traverser on the other side tremble.

Suddenly, Downs shouted, "Master! I get it! ”

Wren instinctively decided that the things this kid understood were definitely not the things he taught, and couldn't help but ask, "Do you really understand?" ”

"I get it!" Downs couldn't be more certain.

But Wren is more certain: what they say is definitely not on the same channel.

Sure enough, in the next second, the surrounding atmosphere began to vibrate.

About forty decibels, the sound of the wind was mixed with a small amount of electric current, crackling.

In the next moment, five lightning claws that looked like hooks appeared on the five fingers of Downs's right hand.

If it weren't thunder and lightning that made up the claws, but bony claws, Wren would believe you that they were the claws of a tiger.

The system prompt is aptly here: [Congratulations to the host's eldest disciple Tang Si for using the level 1 plastic energy magic (electric claw). Once he has successfully mastered three level 1 magics, he will be able to successfully advance to level 1 mage. 】

A certain teacher is stupid: isn't it? That's all right!?
