Under the pressure of absolute numbers, no matter how solid Yangfan Middle School's defense is, it will still not have enough manpower.

What's more, these bone monsters are like perpetual motion machines. As long as they don't die, their impact will have no end. Wave after wave, one wave overwhelms the other, and their momentum is just like the tide.

The survivors of Yangfan Middle School are flesh and blood after all. Under this wave after wave of impact, their physical and mental fatigue will only become more and more serious.

The defense lines of survivors continued to loosen, and several survivors were hit by the bone monster. Although the injuries were not fatal, they also lost their combat effectiveness.

Since there is no survivor defense on the third floor, the corridors and aisles on the third floor are already crowded with bone monsters. The fence on the third floor is also filled with bone monsters. The density is like a flock of birds on a high-voltage wire. Look at it.

It makes one's scalp almost numb.

No matter how hard the survivors on the fourth floor tried to stop them, the bone monsters kept coming one after another, and instead of decreasing, the number continued to increase.

What's even more frightening is that the white-bone monster is constantly attacking, and it's unclear whether it has received instructions from its leader or whether its spiritual consciousness is continuing to awaken.

The monsters actually stacked one on top of another like a stack of arhats, and kept stacking them higher. With two or three monsters, they could easily stack up to the fourth floor.

In this way, the bone monster does not have to jump up from the third floor like before, which also greatly reduces the casualty rate.

After all, the process of jumping provides survivors with an excellent opportunity to kill.

And by stacking Arhats in this way, stacking them high enough to be level with the fourth floor or even higher, you can confront the survivors in the corridor head-on.

Although the single combat effectiveness of the Bone Monster is still not as good as that of a single survivor, the numerical advantage allowed the Bone Monster to quickly gain the upper hand.

The entire fence was densely packed and soon became a wall, airtight, and the bone monsters below were still piling up, continuously increasing their numerical advantage.

One was ebbing and the other was ebbing, and the war situation soon became serious.

Originally, a survivor might only need to take care of one or two bone monsters at the same time.

And with this dense wall of monsters, each survivor may have to face five or ten monsters at the same time.

Not to mention a survivor with only two hands, even if he had three heads and six arms, that would be enough.

Not only that, the top layer of bone monsters besieged the survivors, while the middle layer of bone monsters attacked the fence of the corridor.

The fence of the school building is probably a wall that reaches just below the chest of an adult. Although it is also a reinforced concrete structure, under the continuous attack of the white-bone monster, the fence is obviously unable to withstand the broken lime cement.

The crumbs continued to fall down, and the dust flew up, choking the survivors to cough repeatedly. Moreover, their vision was obviously affected to a certain extent.

Fortunately, at this time, the survivors on the fifth floor saw the situation below and began to use their height to attack some bone monsters on the fourth floor.

If weapons are within reach, attack directly with weapons.

If weapons are out of reach, lift heavy objects and throw them downstairs.

This method has a slight impact on the bone monster below, reducing some of the burden on the fourth floor.

But these alone are obviously not enough, because this attack method has limited damage to the bone monsters, and they can quickly organize a new wave of attacks.

This attack posture is like the ancient ants attacking a city. As long as there are enough, they will surely overrun the city sooner or later.

The most fatal thing now is that this wall of bones has formed. It may not be possible to retreat from the fourth floor to the fifth floor through the previous method.

The fence of the corridor is already in a high-risk area. If you try to climb over the fence to the fifth floor, you will be attacked by countless skeletal monsters at any time.

The only way out now seems to be the classroom behind me.

Climb up to the fifth floor through the window at the other end of the classroom.

This plan has been planned before, but no one supports this method unless it is a last resort.

Once you retreat into the classroom behind you, the Bone Monster will inevitably rush in. When the Bone Monster realizes that the back of the teaching building can also become a breakthrough point.

So invisibly, it is equivalent to letting the bone monster find a new gap.

The Bone Monsters don't have to worry about not having enough numbers to besiege these gaps, but the number of survivors at Yangfan Middle School is only two or three hundred, and every time one is sacrificed, one will be lost.

The road behind them is the last resort. Try not to be exposed until they are in a desperate situation. Otherwise, once they are surrounded by bone monsters on all sides, they will have no choice but to defend the road.

There is no way out!

"Captain, I can't hold on any longer!"

"I'm almost out of strength. We have to retreat to the fifth floor immediately!"

"If we don't leave, we won't be able to leave!"

"Let's go? How can we go up to the fifth floor with so many bone monsters?"

"Let's go through the classroom behind us! Open the classroom door, let's go through the window on the other side! Isn't it much easier than climbing over the fence?"

"No! The other side has not been exposed yet. Now these bone monsters have only surrounded this side. If the retreat from behind is exposed, all retreats will be cut off!" The captain of the fifth team flatly refused.

"How long have we been talking about a way out? If we don't leave, we will have to explain that we are here!"

"If we can't survive now, who will be left with a way out?"

While talking, several more screams came from the corridor, and two more survivors were stabbed by the bone monster, screaming and retreating from the defense line.

The already weak defense line suddenly became precarious.

"Senior Jingjing, do you think we should retreat?" The captain of the fifth team split open a bone monster and asked loudly.

Han Jingjing was dripping with sweat all over her body at this moment. The bangs on her forehead were stuck to her face due to sweat, and she looked a little tired.

She could obviously see that in the current situation, if no measures were taken, the defense line on the fourth floor might not last for more than a minute before the entire line would be breached.

Immediately he grabbed it from his backpack and found two magic pills, one on the left and one on the right.

"Everyone, step aside and lean against the wall!"

Leaning against the wall means giving up on blocking the bone monster on the first line of the fence.

However, everyone was very nervous at this time. When they heard Han Jingjing's order, they subconsciously followed it and retreated across the board, relying on the classroom wall behind them to organize resistance.

Han Jingjing scolded and waved her arms left and right.

The two magic pills, one on the left and one on the right, disintegrated in the air.

A fierce strong wind suddenly blew up at the scene, and the rustling sound suddenly turned into the sound of golden swords, like countless swords waving in unison.

The air flow stirred up by the magic pill quickly condensed in the fierce wind and turned into countless wind blades, falling crazily on both sides of the corridor.

The wind blades melted away and were as dense as hailstones, at least hundreds of them.

Cha-cha-cha!

When the wind blade fell on the bone monster, it was like a hot knife cutting through butter. It cut through with a crisp sound and split into two pieces.

Hundreds of wind blades covered almost a hundred meters on both sides of the corridor.

Each wind blade can kill a bone monster almost accurately.

Unfortunately, once the wind blade is cut down and comes into contact with the target, the attack power will disappear.

Fortunately, the utilization rate of this wind blade is extremely high, and almost no wind blade is missed.

It took just a few breaths to cut through the mess with a sharp knife. The wall of bones composed of hundreds of white-bone monsters, which originally filled the gap between the third and fourth floors, was swept clean in an instant.

There are no monsters left.

Countless limbs fell from the air and smashed into the bones below.

Some unlucky bone monsters were even stabbed by sharp bone stumps and suffered the same fate as pond fish.

Several hundred white-bone monsters were wiped out at once, which was a somewhat scary number. Even though there were many white-bone monsters, a large corner was still missing.

There was also a thick layer of debris piled up below.

The most important thing is that the bone monsters below seemed to be suppressed by this powerful attack. They stopped their offensive for a while and did not continue to attack.

Although they did not continue to attack, these bone monsters did not retreat either. Instead, they piled up below and kept making low-pitched roars.

The ice-blue white bone head also let out a long roar, and its empty pupils seemed to be filled with infinite evil intent, and it was unclear what the intention was.

And all the survivors in the teaching building, no matter which floor they were on, had a panoramic view of the scene just now, and their hearts that were originally hanging in their throats finally dropped back.

In any case, the current crisis seems to have been resolved.

"Senior Jingjing is mighty!"

"It's up to these talented seniors to take action!"

"I'm very curious, how did Senior Jingjing do it? I seem to have seen what she inspired just now?"

"Is it a magic ball?"

"Amazing!"

"Is this an awakening skill? I've heard of it before."

"Don't you ever hear that! Who are you listening to? Are you talking in your sleep?"

The survivors on the fourth floor were all a bit incoherent, some were grateful, some were happy, some were excited, and most of them were happy.

Be glad that you are still alive.

At that moment, many people even suspected that they might not be able to survive tonight.

Maybe, tonight is the last night of my life!

What does it mean to survive from a desperate situation, and what does it mean to fight back from a desperate situation?
