The 13th floor is different from the normal floor. It has no ordinary classrooms, only four halls and some utility rooms. Each hall is extremely spacious. It is generally used for large lectures, large debates and even large ones. Indoor performances, even if you sit on hundreds of people, don't look crowded.

Now, the four halls on the 13th floor already have a feeling of being overcrowded. I am afraid that 90% of the survivors of the entire building will gather here. It is estimated that there are close to two thousand, and they look up. All the people who saw it were panicked, or scared and crying, or scared faceless boys. The spread between the crowds was no longer panic and anxiety, but a faint despair.

This... What the **** is this?

The end of the world is coming? Or am I having a nightmare?

Why did you suddenly run out of so many bugs, horrible heads, swearing bones, my God... Now is not a peaceful era, a society ruled by law, how can you die so many classmates at once, who will tell me this? not true!

Nearly two thousand people were scattered in the four halls. Although the students were all together, no one felt a sense of security. Instead, they shivered, and some only knew that they were crying, and some were in a daze. Some feared and crossed the cross on the chest, praying that God sent a heroic angelic army to save them.

It is a pity that this time is not the angelic corps of God. Even if the Buddha sent out 18 arhats, it was too late, because they found that a group of green stripworms flew outside the window!

These long strips of insects have a ring that is a bit like a silkworm, but it is hundreds of times larger than a silkworm. Each head is one meter long and has a diameter of almost twenty centimeters, plus shiny green skin. It looks like a long winter melon!

What is more contrary to the common sense is that the long-legged worms have thin wings similar to bees, and they slap sharply, even if they are not flying fast, but when they are in groups, seven or eighty. When the head swarmed together, everyone saw the dead souls!

"That is... what kind of bug is that, so disgusting!"

"Who knows what it is, anyway... they must be terrible, just like the red giant worm, who can bite the waist of my roommate in one breath..."

"Ah, they are flying towards our hall, what should I do?"

"Wow, haha, dead, dead! It seems that we are all finished! No one has saved us!"

"Don't be stupid, don't be stupid, those bugs are invincible, they are so cruel, human beings are not their opponents at all... A Tao, it's better for us to jump off the building and die..."

"No, no! Can everyone sit and wait? Absolutely not, we have to live, we must do something!"

"Boys! Boys quickly organize resistance!"

"Girls back! Back!"

"Don't panic! There are five or six hundred people in our classroom. The worm has only come in at least twenty. We have a huge strength advantage! As long as we unite and fight bravely, we can still repel those worms!"

"Hold! This is the old chair found in the sundries room... and the wooden sword of the Kendo community, the strong boys are preferred!"

For a time, the classmates and teachers in the four halls all boiled up, tangled in a mess, even if some old professors desperately organized some boys to form a self-defense group, it was not effective. After all, the morale was really low, and the weapons were super simple. The hall is full of crying screams, where can you bring enough courage to form a self-defense group for the war-torn student?

Soon, those green bugs have already flown to the window!

Everyone is in the heart! Hold your breath!

The window is a layer of tempered glass of good quality. The thickness and hardness are up to standard. Even the football that is fully kicked out must not lose the window. The worms look like silkworms. Is it impossible to break the window?

The higher the hope, the higher the despair. It turns out that the insects from the insect world are absolutely beyond everyone's imagination!

When the students saw the green bugs, it was like a funnel that spewed a liquid of liquid, and all of them were crying!

But when I saw the alloy glass, I burst into black smoke, and the glass quickly melted into a loop of holes!

"Impossible! Strengthened glass is not metal, how can it be corroded?"

"A terrible acid!"

"It’s finished, it’s finished, the liquid that is sprayed is definitely super concentrated acid that is several times more than the water of the king. If there is a drop on the skin, I am afraid it will quickly erode the body...”

"I am! It is still against the fart! No, absolutely not. If you fight against the kind of insects that are full of acidity, if it is splashed into the body by acid... I will have no bones, completely turned into nothing, ah. This wooden sword is still for you!"

At this time, the tempered glass has been eroded out of a large enough hole, and the first green worm suddenly flew in!

Everyone had scalp tingling and couldn’t help but retreat, but there was also a brave boy who took the chair and slammed it over. The speed of the sulphate was not fast, and there was not much vigilance. So the chair that flew into the head hit the head and made a "squeaky" sound.

"Hey! Good job!"

Everyone saw a morale, it seems that the worms are not invincible, as long as they carefully launch a "remote attack" on them, they can still hurt them!

However, the sulphate did not suffer much damage, but was provoked, and slammed, and it raised his head, a full-scale cone-shaped mouthpiece sprayed toward an old professor closest to it. Give a rush of water!

The old professor was swaying. The next moment his chest began to burn like a ash, completely smouldering, and then spread from the chest to the head, abdomen, and limbs. In less than three seconds, there was only one beach odor on the ground. The turbid liquid of the nose can no longer find evidence that the old professor survived!

The students looked pale and white. It was already disgusting to think that the red-headed beetle was bitten in the inch, but witnessed that human beings were killed by the sulfuric acid worms, and it was known that there was such a creepy death in the world!

God of mercy, how can you allow such a ferocious sulphate to appear in the world...

For a moment, the fear of the students has reached the apex.

However, when fear reaches its zenith, human beings will have a polarized attitude, or they will be completely scared to be overwhelmed, or they will not know what is called fear, and they will fight back!

Next, more than 20 sulphate worms outside the glass also flew in, and more than 500 students silently had thirty or forty people holding their extremely simple and rough weapons to come forward and dying. .
