"Lin Tuo! Come on! The madmen are coming! ”

"Damn! The intelligence is simply not right! There are three times as many troops on the other side! ”

"It's a trap! Come on! ”

"They're catching up! Hurry up and !! ”

"The road ahead is blocked! We have no other exit! ”

"Kill it! There is no other way!! ”

"The blood in Yebei can't be stopped, Captain! What to do! ”

"We are a team! You can't give up your companions even if you die! ”

"Captain Wu Lei is injured! Yes!!! His legs!! ”

"Wu Lei, how are you! Sober up, we'll be able to get out in no time! ”

"Captain, I'm coming to the palace! You guys go! ”

"No! Wu Lei, we won't give up on you! We'll definitely be able to get out together!! ”

"Go, go, !!!!go,

"Wu Lei !!!!!!!"

……

"Lin Tuo?" Lin Tuo woke up suddenly, and Mr. Yamada looked at Lin Tuo with his thick eyebrows, "Classmate Lin Tuo, did the teacher have a holiday with you?" Why do you look at the teacher with that kind of look? ”

The other people in the class also looked at Lin Tuo with puzzled eyes, although Lin Tuo had just had a conflict with Alius, but everyone felt that Lin Tuo was not at fault, he was still a polite and polite big boy who smiled at everyone in everyone's eyes, but the hateful eyes just now not only made Mr. Yamada frown and disgusted, but also made the classmates who had just looked at him fearful!

That's a kind of look, with a crazy, undying look!

Lin Tuo hurriedly lowered his head, "I'm sorry, teacher, I just lost my temper, and it wasn't aimed at you, teacher, please forgive me." ”

Mr. Yamada thought about it for a while, and roughly imagined the reason for Lin Tuo's expression.

Probably some relatives died at the hands of those crazy people. Mr. Yamada thought with some sighs.

Thinking of this, he couldn't help but look at Lin Tuo with a little tenderness in his eyes, dying at the hands of the enemy was a heroic sacrifice, and his descendants were worthy of respect.

"Then let me give you a brief introduction to the [Cardinal Sect]." Teacher Yamada glanced at Lin Tuo, the extracurricular knowledge that should be taught still has to be taught, this is all related to the lives of the students, and you can't cut corners because of personal emotions, "[Cardinal] is a church that believes in the Nian Beast, they believe that human beings are moths in this world, and the appearance of the Nian Beast is the punishment of God for seeing the viciousness of human beings, and human beings should not resist in the face of God's punishment, so those are a group of anti-human madmen, who carry out terrorist attacks in various cities and destroy the internal peace of the entire human race.

Moreover, the people of the [Cardinal Cult] are not only inhumane madmen, but also a group of powerful villains, they conducted secret experiments to develop the [Nian Beast Armament], with magical attainments, most of the [Cardinal] cultists have very strong strength, they do not have a specific division of strength, maybe there is, but we don't know. ”

"Teacher," Shuda said with some confusion, "what is that [Nian Beast Armament]?" ”

"This is a little far away from you," Yamada shook his head with a smile, "When I was a sophomore, there was a special course to explain the Cardinal Sect, after all, they are numerous and are the great enemies of mankind, and you will also come into contact with them when you go to the battlefield in the future."

Next, I'm going to explain how to dissipate the enemy's array. ”

As he spoke, he stretched out his hand again and constructed the [Illumination] array, "Let's take the Illumination as an example, now that we know that the central hub is on the right side of the array, how do we destroy it?" It's not impossible to physically attack alone, but the probability of success is small. “

Yamada used his left index finger to pass through the central hub of the magic array, but the magic circle only shook for a moment, and there was no sign of dissipation, "That's because I said before, Xiangzi has wave-particle duality, and its wave side determines that it has a strong immunity to pure physical attacks." So, how do we dissipate this array? ”

Yamada slowly raised his left hand and smiled slightly, "As long as that's it." ”

It's still the same index finger, but this time, the index finger has a green mang!

Poked at the magic array slightly, as if there was an undetectable explosion sound, and the entire magic array collapsed directly! Turning into bits of blue light and gradually disappearing into the air.

"Actually, the principle is very simple, since pure physical attacks can't work, then Xiangzi must be able to affect Xiangzi, and it would be good to destroy it with Xiangzi. Some people may be about to say, isn't this ability only available at close range? Actually, no, it's because your strength hasn't reached this point yet. ”

As he spoke, Yamada flicked his fingers, and a green light swept through the air, hitting the wall behind the classroom in an instant, leaving a shallow mark.

Although the green light was faintly undetectable, and the speed was extremely fast and impossible to see, but all the students present were the students of the Huadi Demon High School whose strength should not be underestimated, and everyone turned their heads to look at the white mark on the wall, and their mouths opened wide in surprise.

"That'...... What is that? Finger Magic? ”

"Coach, I want to learn this!"

"This is too imba, isn't it?!"

"You've read too many martial arts novels!"

Mr. Yamada clapped his hands and turned everyone's attention back to himself, "Actually, it's nothing at all, to put it bluntly, your strength has not arrived, most of you are D-level or even E-level strength, but as long as you have C-level thinking and control ability, with a little practice, you can easily complete the action I just did." ”

"I see!"

"So we all have a chance!"

"yes, yes, I feel like I'm not far from C-class!"

"Looks like everyone has a chance!"

Lin Tuo looked at his palm and clenched it tightly.

If...... If only I had known such a trick back then...... Is Wu Lei just ......

On the other side, Alius also looked at his palm, his face hideous.

"After this class is over, you can try it, because this is not a very high-end technique, and talented students should be able to learn it quickly," Yamada-sensei said to everyone with a smile, "We have a special term for this technique of dissipating by shooting a thought to hit the local magic array and dissipate it, which is called [countermeasures]." Of course, [Countermeasures] can rarely be used in actual combat, after all, battles are changing rapidly, and there is no time for you to observe the opponent's magic array and find a chance to counteract. “

"Teacher," it was Lin Tuo who raised his hand this time, "and what if it's those high-level magic arrays with many central hubs?" Can destroying only one central hub counter an adversary? ”

"That's a good question," Yamada nodded with a smile and said to everyone, "Like I just said, most magic circles actually have more than one central hub, so is it effective to destroy one of the central hubs at this time?" ”

Yamada raised his right hand, and the blue light appeared! Countless small cyan particles that seemed to be particles flew in the air, swirled, and formed.

One after another the patterns are outlined, and the flower-like shapes seem to come alive, and the thoughts are staggered, whirling, bifurcating, overlapping......

A moment later, a complete array was finally formed in Yamada's hands......

"B-level magic array - [Spring Rain]." Yamada wiped the sweat stains on his forehead, "This is a large-scale continuous recovery magic, which is very useful on the battlefield, but because it is a continuous magic array, it is a great challenge to the total amount of thoughts of the user." You can take a closer look at this array to see how many central hubs it has. ”

The students couldn't help but stick out their heads in amusement, looking at this magic array, counting the meeting points one by one.

"One...... Two...... Three...... There seem to be eighteen! ”

"What the hell, I counted to nineteen!"

"yes, yes, I counted to nineteen."

"Why did I count out twelve......"

"Twelve, you're blind! No matter how you look at it, there are more than a dozen! ”

Yamada raised his thick eyebrows, "Some students answered correctly, this is a total of nineteen central hubs, which is quite complicated in the B-level magic array, how can any student know how such a magic array can be countered?" “

"Isn't it just a matter of hitting one of the central hubs?" Some students asked puzzledly, and some of the rest of the students also agreed.

"Yes, yes, it stands to reason that as long as one point is cut off, the entire magic array will be disrupted, and it will naturally collapse, and the purpose of countermeasures will be achieved."

"I think the same way, as long as one point is gone, it will be difficult to maintain balance in the other points!"

"I don't look like a teacher...... Does that mean cutting off all the central hubs? ”

Mr. Yamada smiled and shook his head, and was about to speak when an indifferent voice came.

"Only by cutting off the central hub with more connections as much as possible is it possible to succeed in the countermeasures, right? The more central hubs are cut off, the more likely it is to succeed, and the countermeasures are guaranteed to be successful before a third of the central hubs are cut off. ”

Lin Tuo held his chin with his right hand, his eyes were clear, and he looked at Mr. Yamada firmly.

"Huh? What is the rationale for this? Lin Tuo, he shouldn't be talking nonsense......"

"Not necessarily...... He's Lin Tuo'......"

Yamada-sensei's eyes gave him a look of surprise, "Oh? Lin Tuo, can you tell us the basis for what you said? ”

On the other side, a smile hung on the corner of Li Liyin's mouth, "[Butler's Law of Separation] says, 'There has been an unobservable internal connection between the already connected sons'. ”

Lin Tuo looked at the classmates behind him, "If it's like what the classmates said just now, then it should be possible to cut off a few patterns to achieve the purpose of countermeasures, and there is no need to introduce the concept of [Central Hub] at all." ”

Li Liyin looked at the surprised gaze of the female teacher on the stage, and there was already a bamboo in his chest, "And the actual meaning of [Central Hub] is: it is the central point where you want to make connections." ”

"Why start from the central point, because the internal connection of the Xiangzi determines that small changes cannot play a decisive role in the impact of the entire array."

"So there is only a central hub, which is the only decisive element of countermeasures."

"Destroy it! Only then can there be hope for success! ”

In an instant, the applause was thunderous!
