After Shirakawa discovered this, he had an idea, and when he was observing, he silently taught the other party a set of claw methods/knife techniques for the high use of the human body's own energy.

This set of knife techniques makes sense, but it's not a profound thing, but it is a technique that Shirakawa has created with reference to the structure of the human body and is completely suitable for the efficient use of knives by the human body.

It is mixed with some high utilization of biological energy, so that the excess energy of the human body is no longer wasted, but moisturizes and strengthens itself.

Under normal circumstances, a lot of the energy generated by the food eaten by the human body is actually leaked and wasted from pores and other places, which is also the reason why many people gain weight and have excess nutrition in peacetime.

And Shirakawa's technique is to use a certain instinctive response stimulation of the human body, just like hitting the knee, the knee will bounce uncontrollably, which belongs to nerve stimulation regulation.

The reason why deep breathing relieves the tension of the human body is because the human body is in a state of rapid shallow breathing when it is nervous, the lung space is not used efficiently, and the oxygen in the air cannot be fully exchanged with the carbon dioxide in the blood.

Deep breathing is a chain reaction that changes the state of rapid and shallow breathing, slows down the speed of breathing to deep breathing that makes high use of lung space, and allows the oxygen in the lungs to be fully exchanged with the carbon dioxide in the blood.

His technique relies on these reactions, as long as he makes certain movements completely, the body will spontaneously move in the process of exercise, and spontaneously adjust the body's breathing rate with the intensity of the activity, fast and slow.

When it reaches a certain level, its human body will be spontaneously stimulated by the respiratory rate, just like dizziness due to lack of oxygen, like a shivering whole body stress like closing most of the pores, leaving the excess energy in its body that will be discharged with the pores, nourishing its body muscles and muscles, and strengthening its own physical strength.

This is an extremely efficient way to use energy, but unfortunately it is of little use to Shirakawa, because he can efficiently use the energy in his body and convert it into the energy of his own golden finger.

In addition, his mutant right claw is still a large energy consumer, and there is no spare energy to waste.

Of course, Bai Chuan would think that it was just some simple skills, for Zhou Yun, who was just an ordinary person before, he was like a treasure for this set of skills, not only learned it himself, but also handed it over to his sister.

The two brothers and sisters, under Shirakawa's silent teaching, even if it is only for five days, because they have sufficient food support, their physical strength has increased greatly, and even their strength has increased a lot.

After all, this skill comes from an earth immortal powerhouse with enough strength to reign as the king and hegemon in the planet!

And he is still the kind of strong person who is very familiar with the various structures of biological flesh and blood.

In just five days, the change is tantamount to a rebirth for ordinary people.

At this moment, even Zhou Xiaoxiao can sneak attack and cut off the head of an unconscious "figure" with a knife, and Zhou Yun can hold the Tang knife without changing his face in the unconscious "figure", as long as the number is less than three, he can kill it by himself.

Don't underestimate this, although these "figures" are not conscious, they are not lower than normal adult males in other aspects, and their strength is even greater because they are not limited by the brain.

Of course, the food that was already abundant began to decrease rapidly, after all, in a building with a type of residents, especially young people, and there is still no fire and electricity, no amount of food can be eaten.

……

On this day, the fifth floor.

The Zhou Yun brothers and sisters, who had finally cleaned up this layer during the day, were sleeping peacefully with knives.

"Ahhh!!h

"Smack——!!

Suddenly, an extremely terrible scream fell to the ground from above, and before it could be, a dull smashing sound sounded.

Zhou Yun and his sister, who were asleep, opened their eyes in an instant, and they were full of energy, how could there be the slightest sleepy eyes of people who woke up normally.

Among them, Zhou Yun came to the window directly with a Tang knife in his hand, glanced at the cat who was already standing here, and was not too strange, but looked down, and saw the situation below through the increasingly damaged street lamp-

It was a humanoid thing that was blurred with flesh and blood, almost a lump of flesh.

However, this scene made Zhou Yun's pupils shrink, because he recognized the clothes on the lump of things!

That's Uncle Wang's!

But why did he fall from the roof of the building at this moment?

What's going on on this building?

However, Zhou Yun was puzzled, but Bai Chuan's heart was a little uncertain.

Things seem to be getting a little bit worse.

In the past five days, Shirakawa, who has almost stopped cleaning the floor below, finally has time to go to the floor above to check the situation of the "monster".

This made him realize that the monster would leave the room full of yellow and red pus every night, and search for Wang Bo and the others among the empty floors

Although Bai Chuan didn't know why Uncle Wang was attracted to the "monster", he knew that Uncle Wang's life was the greatest help to him.

Because Uncle Wang was currently able to hold back the "monster" and prevent it from going down, he would even throw a small amount of food in the house where he rested during the day for a few days, lest it would starve and lose its physical strength to continue to escape.

It can be said that the opponent's tool attributes are used to the extreme.

But now, this useful tool man is dead!

Bai Chuan has finished checking the floor above, and the others have already died, it seems that they died before Wang Bo and the others ran to the top, and the death was extremely tragic, and at this moment, the only few living people on the upper floor were gone.

If there is no living person on it, what will happen to the "monster" next is clear without thinking about it......

Hopefully make it through tonight.

Tomorrow you have to leave this building immediately, you can't delay it!

Looking at the night outside that was still dark, Shirakawa silently decided.

Although he already knew that there were no living people on it, Shirakawa would not escape from the brother and sister overnight.

For humans who can't see at night, touching the dark is an extremely dangerous thing, if they don't have special training, their combat effectiveness during the day is very high, and at least seven or eight points at night will be removed.

At that time, I am afraid that if the "monster" does not come, my own people will lose their position, which will be funny.

I woke up in fright, and after a while, the two people and a cat in the house hurriedly fell asleep again.

Tick – tick – tick –

In the middle of the night, the clock keeps moving forward with an imperceptible sound in the silent night, giving people a sense of tranquility.

"Bang ......"

After a while, there was a crisp sound of footsteps on the silent floor, and the sound seemed to start getting closer and closer.

"Bang ......"

It's closer, it's getting closer!

The sound of crisp footsteps began to make a faint sound of flesh sticking to the floor, and a sound similar to treading water.

It was in this moment, in the darkness.

A pair of golden cat eyes slowly opened, flickering with an eerie glimmer in the darkness.

It seems that I won't be able to sleep well tonight.

Bai Chuan straightened up and moved his body, came to Zhou Yun's side, stretched out his cat's paw and slapped his face a few times with the soft meat pad unique to cats.

"Uh-huh——?"

In the dark, Zhou Yun felt a slight slapping sound, and he also woke up again.

A little dazed, he looked at the cat in front of him, and the sound of approaching footsteps not far from the door, and immediately sobered up, subconsciously holding the weapon on the side and sitting up.

After gently waking up his sister Zhou Xiaoxiao, Zhou Yun, who was about to approach the door to attack, paused, lowered his head and looked at his feet, at this moment his trouser legs were being pulled by a cat with its claws.

Seeing him looking, the cat shook her head humanely.

In just an instant, Zhou Yun's heart became solemn.

He knows how strong the cat's strength is.

In the past, even if he encountered a special "figure" on the floor, he never flinched, let alone stopped him and made him retreat, but watched him from the side, and would step forward and claw him as soon as there was danger.

But now, he grabbed his trouser leg and shook his head.

It's a monster out there!

In just a moment, one action, Zhou Yun's mind was full of thoughts.

Seeing that the young man stopped, Bai Chuan also loosened his claws in time, understanding that the other party was already clear about the situation, and then he jumped lightly to the window and looked back.

Zhou Xiaoxiao reacted immediately, she silently approached the backpack next to her with her bare feet, where there was a thick rope they had found before, she held the zipper with her fingers, and carefully opened the backpack,

"Zizi ......"

A subtle and inaudible voice sounded in the silence of the night.

At the same time, Zhou Yun also hurriedly looked back and looked around, staring at an extremely heavy wooden bed in the corner, trying to move it near the window as a binding object for fixing and draining strength.

"Smack."

"Drip-"

The footsteps outside the door stopped, and an indescribable smell faintly came from outside.

Under the ineffective solar light bulbs in the corridor, huge shadows slowly squirmed in through the cracks in the doorway, and under the crisp dripping sound, the yellow and red color looked at the disgusting pus flowing in, mixed with a palpitating feeling, as if the heart was being grabbed by something invisible.

Seeing this, Zhou Xiaoxiao, who was observing the outside from time to time, paused, and his little face suddenly turned pale.

If it weren't for the fact that she had begun to increase her strength in the past few days and killed a few "figures" at close range, the girl would have stiffened with fear at this moment.

But after this, both the girl and Zhou Yun became more careful, and their movements became more and more subtle.

"Boom! - Click......"

Suddenly, a loud noise appeared outside the door, followed by the sound of the door being slammed open, and a large number of heavy objects piled up behind the door began to be shaken.

There was a heavier knock on the door...... No, maybe it's the sound of the door slamming.

The metal gate was smashed and roared, like a raging beast knocking on the door.

The gate is deformed and twisted at a speed visible to the naked eye.

'Quick! Fast! ’

As the door became more and more crumbling, the movements of the two people in the house became more and more urgent, Zhou Xiaoxiao, who had already taken out the rope, hurriedly put the bag on his back, put it directly on his chest without caring about the zipper, and came to his brother's side to help him move over, and then began to tie up and throw the rope.

The two siblings are anxious about escape, what about Shirakawa?

Shirakawa cut through the glass above the window and went around the outside wall into the corridor outside, where you could see the specific appearance of the monster standing in front of the door.

At this moment, that monster was more and more powerful than when Shirakawa saw it before.

And the appearance is getting more and more deformed!

The place where he stood completely turned into a pool of yellow-red disgusting pus, all secreted from the various granulations on his body that were secreted between the various squirming of the flesh.

Every time he swung his right fleshy arm and slammed into the door, a large amount of blurred flesh was splattered, causing blood and pus to splatter more and more.

At that moment, the slamming of the door stopped.

The black mist human face emanating from the monster slowly turned around.

Revealing a slightly numb female face, the next moment when she saw Shirakawa staring outside-

"Ahhh——!!h

A piercing, high-pitched scream rang out from the face of the man covered by the black mist's palm.

Circles and circles of transparent ripples spread in all directions.

The walls began to tremble faintly, the countless dust on the ground jumped slightly, and the glass-like windows could not bear to break in an instant.

"Buzz!!"

Countless black mist surged, and the flesh buds jumped, converged, and twisted!

In an instant, a terrifying ghost claw burst out of thin air and grabbed towards Shirakawa.

"Ahh......hh

At the same time, there were several screams from the floors below the floor that were facing the direction of the "monster's" screams, which were survivors who could not withstand the power of high-frequency screams, of course, after these screams, it was not necessarily a survivor.

Seeing the ghost claw attacking, Shirakawa also had a lot of strength, jumped and hung on the wall at the moment of crisis, constantly throwing himself out with the help of inertia, and then fixed it on the wall with his sharp right claw, repeating the previous action.

"Boom!"

There was another loud bang, and the claws that slammed into the ground from within the floor, causing the earth to crack several cracks.

In the next moment, the ghost claws turned into countless withered flesh buds and the black mist slowly dissipated.

However, the "monster" that was still at the door before came to the position where Bai Chuan was standing before as if he had teleported, and a pair of scarlet and resentful eyes continued to scan, and then another ghost claw was grabbed out.

Like the withered claws of giants, they continued to extend from the floor, grabbing through the concrete building like tofu, leaving countless pieces of fine rubble.

However, it just couldn't hit Shirakawa, who seemed to be as small as a flea fly.

Even after Bai Chuan caught a glimpse of the two siblings who had fled from the fifth floor to the ground on the way to escape, his eyes were cold and he began to fight back.

Even if his current cat body makes it weak, but what?

The enemy is nothing but a "reckless man" with no strength and no wisdom!

Almost all parts of the outer wall of this building have already been crawled by him.

At this moment, he had already memorized the structure in his heart, and between the climbing and throwing again and again, the huge ghost claws burst out again and again, and each time he grabbed out, it meant that the building was grabbed out of a huge hole.

After grabbing it in a row, terrifying holes began to slowly emerge around the fifth floor of this building......

"Not good!"

Fleeing to the ground below, hiding in a relatively safe place, Zhou Yun, who had been staring at the cats on the outer wall with concern, suddenly screamed.

In an instant, he looked at the tall building that was becoming more and more dilapidated and began to crumble, and suddenly grabbed his sister's little hand and fled into the distance in a hurry, no longer caring about waiting for the cat.

Because he finally saw the reason why his cat didn't run away from the building!

Thanks to the explosion of the "monster" on the building, a large number of unconscious "figures" around him almost disappeared at this moment, leaving only two or three scattered groups, and those phantoms completely fled from here the moment their ghost claws appeared, as if the other party was some earth-shattering monster.

At this point, it was only the back side that had borne part of the power of that sound wave to get the Zhou Yun brothers and sisters, and it was only the blood that spilled from the seven orifices, and it was not a big problem.

With the departure of the Zhou Yun brothers and sisters, the situation above the building is becoming more and more critical!
