In an open classroom.

The on-screen animation sent chills down Lindy's spine.

On the screen, a lizard-like monster is constantly changing its body, the black body sometimes turns into a puddle of liquid and wriggles like water, sometimes scatters like grains of sand, but finally they are intact together, revealing the blood-colored eyes under the white mask.

Then a warrior with a knife appeared on the screen, and the knife fell on the lizard's head, and the lizard's body immediately turned into a puddle of black water, but finally coalesced together.

The sword-wielding warrior stepped back, and a warrior with a submachine gun appeared on the screen, firing a wave of bullets at the black monster, and the monster was beaten into a sieve, but soon the holes were closed again.

Shout~~

A missile flew over, and it was blown up for miles, but under that scorched earth, a pool of black water was still wriggling and condensed together!!

At the end of the animation, the female teacher appeared on the screen again:

"In the animation just now, it is the lowest-level variety of ghasts [Creepers], although they are the lowest-level and weakest, but the characteristics given to them by fluid creatures make them invincible when encountering various attacks!!"

"The lowest-level ghast creepers are invincible against human thermal weapons, how can they fight?" Lindy felt terrifying.

The on-screen tutorial continues:

"The so-called fluid is a substance that will continue to change under the action of any weak force, and ghasts have fluid characteristics, which make them not afraid of thermal weapons, which also makes humans at a disadvantage from the beginning in the battle against ghasts!"

Let's take a look at the classification of ghasts.

Currently known ghast breeds are divided into:

Creeper: The lowest ghast, who likes to eat human flesh.

Bone-eating ghasts: Human flesh can no longer satisfy their appetite, this type of ghast not only likes to eat people, but its sharp teeth can easily shatter human bones, although the number of such ghasts is small, but each appearance will cause disaster.

Blood-eating ghasts: Flesh and bones are just low-level nourishment, blood is their favorite, and the blood of the fearful makes them endlessly memorable and crazy, this is the most abundant species in the world today.

Possessed ghasts: Also known as parasitic ghasts, they are the elite of ghasts, and they are also parasite-like beings, they choose their masters and devour, relying on their attachment to the human body, devouring the host's essence and soul little by little. Blood can be obtained from others, and the host's little by little soul consumed by fear is their ultimate pursuit!!

”

Each time the teacher explains a type of ghast, the corresponding picture of the ghast will also appear on the screen.

Lindy compares the images and discovers that the ghasts all share the same features, a black body, a white mask-like face, and blood-red eyes.

In addition, the creeper looks like a lizard, and eats bones, blood, and possessed ghasts, all of which are human-like, with hands and feet.

The difference is that the Bone-Eating Ghast is a little stronger, like a burly man, while the Blood-Eating Ghast is smaller and resembles a young child, and the Possessed Ghast has a long body, which is most similar to a human.

"Ghasts are fluid creatures, even missiles are useless against them, what can humans do to fight them?"

And then, there is a corresponding explanation on the screen:

"Devouring humans can accelerate the reproduction of ghasts, which also makes the number of ghasts more and more, in order to solve the ghasts, the public enemy of the world, the alliance government has established the [ghast research institute] and the [Shura Academy] respectively.

The former focuses on the development of science and technology, through the study of ghasts, and uses the power of science to find out the weaknesses of ghasts, and develop corresponding weapons to fight them.

The latter idea is to fight the ghast with the power of the ghast, relying on the control of the possessed ghast, and using the power of the possessed ghast to kill the ghast.

Now that both departments have their own ways to fight ghasts, it is no longer impossible to fight ghasts.

Dear students, please do not study hard, but at the same time, please remember your mission, even if you become a Shura, you must fight for humanity.

Shura Academy, proud of you!!"

The open class is here, and the class is over.

Next, it's time to loop the playback.

After reading it, Lindy thought to herself:

"In this open class, the two major institutions under the alliance government are the Ghast Research Institute and the Shura Academy, both of which have the power to fight against ghasts, and obviously the ghast research institute uses the power of science to fight against ghasts, but didn't it be mentioned in the previous animation that even missiles can't hurt ghasts, so what else can fight against ghasts in the scientific power?

Lindy shook her head.

I thought that it should not be nuclear weapons, because once nuclear weapons are used, it will hurt the enemy by 1,000 and damage 800 by itself.

It is the enemy who is hurting, but it is the land of the human world that is destroyed, and as long as the alliance is not stupid, it will definitely not use nuclear weapons on a large scale.

Besides, after the first disaster, wasn't the production and development of nuclear weapons banned?

But if it's not nuclear weapons, then what kind of scientific power is it??

Lindy knew that this should be a secret of the Ghast Research Institute and even the entire World Security Alliance, and would definitely not mention it in this kind of open class.

But I was still curious.

Just as he was puzzled, Lindy suddenly noticed that someone was staring at him, and when he turned around, he saw that the student named Zhang was looking at him for a moment.

"Why is he still here?"

Lindy didn't have time to deal with him, and the public class took nearly an hour, and it was almost four o'clock in the afternoon, and he still had several tasks to complete.

"The third task is to go to the ghast specimen room to visit the ghast specimens and have a certain understanding and cognition of the ghast signs. ”

Lin Di took the paper, dodged Zhang Chuming, who wanted to peek at it, and vaguely recognized the location of the specimen room on the sketch he had drawn, and trotted over.

Behind him, the strange guy was still following.

Forget it, leave him alone!

I guess the head is not normal.

Arriving in the herbarium, Lindy came into contact with a ghast other than "the one" in his body for the first time.

There are all four ghast breeds here, all of which are sealed in clear vessels filled with special liquids.

"Ghass are fluid lifeforms, how did these ghasts in transparent vessels get caught??" Lindy scratched his head.

Too many questions.

Originally, as a rising star student, he had a personal assistant to answer these questions, but Huang Fusheng was good, left a piece of paper, and became a shopkeeper, this portable assistant teacher is too unqualified.

"Creepers. ”

Lindy came to the first specimen.

Directly in front of the specimen is a plaque detailing information about the creeper, which is more detailed than the information mentioned in the open class.

After reading the detailed introduction, Lindy carefully looked at the creeper through the glassware, his dark complexion shimmering in the liquid, his white face had a calcified texture, and his crimson eyes were like blood coagulating.

"It seems to have a black spot in its eyes, it should be a pupil, which is quite similar to the anatomy of the human body. ”

Lindy takes a closer look.

Since the creeper's scarlet eyes were so small that they had to close the distance and adjust the angle to see clearly.

Curious, seeing the ghast entity for the first time, Lindy almost lay on the glassware, adjusting her posture very awkwardly.

But suddenly, the black dots in the creeper's scarlet eyes actually moved.

This sudden change made Lindy take a step back.

"I'll go, my eyes are moving!!"

"This specimen is a living !??"
