Robb understood as soon as he heard what this guy said, this is a **** old school.

No matter in any world, in any era, in any social environment, there are always some conservatives. They always rely on their old experience to reject new things, thinking that new things are useless and all rubbish.

One of the more famous is a government called "Qing". They feel that bows, arrows, swords and spears are enough to be invincible in the world. The steam engine that people gave them was locked into the warehouse, saying that "we don't need this kind of garbage."

Then they became the tears of the times!

Such people not only exist in ancient times, but also in modern times, and there will be in the future.

For example, many people now say that online novels are rubbish, and the writing is full of noobs, and the words used in classics are more beautiful. They don't know that since ancient times, writing has been developing towards colloquialization, and the process of colloquialization has never stopped.

Pushing forward for decades and hundreds of years, the classics in their mouths were all small white books that were disdainful by scholars and literati at the time.

Ah, far away! get the point.

When Robb heard the stubborn tone of No. 32, he knew that this product was not saved. It's better not to talk to him. He can fully make his own multiple condition judgments slowly after returning to Westwind Town. There is no need to fight with him. The twelfth was a waste of words.

Robb stopped talking!

Thirty-two said: "Okay, this lesson is too simple. It doesn't take much time to finish it. There is still more than an hour until today's school time. You can arrange your own time later."

He sat on the chair behind the podium and flipped through a dark magic book.

The students in the church also started to play their own games, but Robb was not as greedy as they were. He wanted to quickly review the "trigger rune" he had just learned, and also wanted to try the most basic multiple conditional judgments.

However, he is a poor man in this world. He has never had the material to make magic props on the spot, and he can't draw magic circles. If he wants to do a practice, he has no props to practice, which is very embarrassing.

I had to turn to the tablemate next to Marian Cotton, and smiled: "Miss Marian, I want to study the multiple conditional judgments just mentioned, but you also know that I am super poor. Can you sponsor me? Some materials, or help me draw a magic circle?"

"Oh?" Marianne smiled: "Your last invention made me earn one hundred and fifty gold coins. Of course, making gold coins is just a small matter. The key is that my Cotton family has been praised by Her Majesty, so I I'm happy to help you. I didn't bring so many materials, but there is no problem in drawing a magic circle for you."

Marianne is a fire magician. Therefore, she helped Robb to draw a flame magic circle. The simplest and most basic one is "explosion trap". This kind of magic circle is actually a "flame explosion technique." Fenghua was in the magic circle, and when someone stepped on it, it was triggered, and then with a "boom", the enemy was blown into the sky.

It was still in class at this time, so the magic circle was drawn directly on the corridor between the two rows of desks. The students on both sides bent over to look at it. Of course, everyone recognized this as a basic "flame explosion."

Marianne smiled: "I'm done drawing, what do you want to do with it? Do you step on it? Oh, better not! It will blow up the classroom."

Number 32 also flipped through the Dark Magic Book and said, "Remember to wipe off the magic circle in a while, don't really blow up the classroom."

Robb smiled and said, "I just want to change the trigger rune."

He squatted next to the magic circle and carefully looked at the trigger rune on it. Before he could not understand the magic circle at all, but after today’s lesson, he has understood a lot, and soon he found the trigger rune in the circle. String, that is a long string of symbols, these symbols are similar to "programming language", each symbol represents a meaning.

The connection is "being, man, stepping on me, then, start"!

It is really very simple to understand if it is understood as a programming language. Robb pointed to the two runes of "Someone, step on me" in this set of conditions and said: "Here is the key condition."

"Yes!" Marianne nodded: "This is the key to triggering."

Robb lifted the pen and dipped it with "Magic Essence Ink". Next to the position of "Human", he squeezed and drew a rune representing "Human", and said with a smile: "Now, does it become "When, everyone, step on me, then, start.""

Marianne thought about it carefully: "Huh? It seems to be! When you draw like this, it means that at least two people must stand up before it will be triggered."

Robb smiled and said: "In this way, one enemy can't trigger it. It takes two enemies to trigger. If I draw a lot of'people' symbols here, then it needs to stand on a large group of people to trigger it. Then we can prevent the enemy scouts from triggering it, and it can be used to blow up the enemy's main force."

One sentence awakened the dreamer, and Marianne yelled "Yeah": "You are right! The enemy scouts will always destroy our magic circle, but you only need to draw a few more people. , The scout can't activate the hidden magic circle, only the enemy's main force can blow up the opponent's main force at that time!"

All of a sudden, she seemed to understand the meaning of Robb's "multiple conditional judgments", but she knew it at a very basic level, and she was only a little bit close to the point.

Robb smiled and said, "I will try to draw a few more conditions..."

He picked up the pen and scribbled in the magic circle. Suddenly, accidentally, an extra drop of ink dripped from the tip of the pen, accidentally connecting the two symbols together.

Marianne was shocked: "No! Hurry up!" After she finished speaking, her feet fell on the ground, and her whole body floated backwards in an instant.

"Huh?" Robb was shocked: "What's wrong?"

Before he finished saying "what's up", he felt the magic circle in front of him explode with a "boom".

Flame explosion technique!

A heat wave rushed to both sides, and the students on both sides flew backwards at the same time. These people are not ordinary people. While flying, all kinds of life-saving magics are turned on at the same time, ice armor, wind shield, fire wall, earth wall... …There are so many tricks and colors.

At the same time, the surrounding desks were also blown up, and the glass windows were all shattered. The broken glass and the wood chips of the desks and chairs flew in all directions together, and all kinds of messy things were spinning in the sky.

Flying all over the sky, a barren, full of wind and snow and tears turned into dust!
