roar Halisa heard the sound and roared as if she was disturbed.
Dudian looked at the girl's beautiful and ferocious face and slowly stopped laughing.
By now, he had already recognized the reality.
The proud but gentle Halisha she once was can no longer come back.
Miracles will not favor him.
That being the case He can only create miracles by himself "I will definitely let you return to your original appearance."
Dudian stared at her with extremely gentle eyes and whispered softly, like a whisper to the most passionate lover. roar Hearing the sound, Halisa roared even more ferociously.
Dudian stood up slowly.
Although he was in a desperate situation at the moment, a strong desire to live burst out in his heart.
The sadness, depression, and dejection that he had felt after seeing Hailisa's corpse all disappeared from him at this moment. .
"When a person's stomach is hungry, it will growl.
This is an instinctive reaction.
This is a conditioned reflex."
Dudian took a step forward and came to the paw that Hailisa tried her best to reach in.
His eyes were extremely gentle, "Believe me, I It will definitely restore you to your original appearance.”
Halyssa roared angrily and struggled to squeeze into her arms.
Dudian saw that her sharp fingertips had grown slightly, and the confidence in her eyes increased a bit.
Conditioned reflex, this phenomenon does not only exist in conscious living bodies, but also in unconscious walking corpses.
When he was still a scavenger in the early days, he observed that walking zombies are attracted to sound sources and heat sources.
Even if the walking zombies' sensing organs are completely rotted, they can still accurately track prey and lock the prey's position through caused by other factors such as this.
And this just proves that the walking corpse also has the ability to receive information and analyze it.
Although their analytical ability is very weak, they are not attracted by each other's footsteps, but are attracted by each other's roars, but it shows that they still have a certain degree of information analysis ability.
The existence of these abilities means that they also have conditioned reflexes Reactions such as gathering together when hearing a sound source, smelling blood, and secreting saliva are all conditioned reflexes.
Moreover, precisely because they have no consciousness, the actions of the walking zombies are entirely based on conditioned reflexes.
If it hadn't been for the flash of inspiration that flashed in Dudian's mind when his stomach growled with hunger, he wouldn't have taken the conditioned reflex phenomenon seriously, which he had already seen for a long time and didn't even include in his thinking.
However, this phenomenon, which people hardly notice but is common, made him burn with incomparable hope and belief.
What can conditioned reflexes do?
When a finger is burned by flames and hurts, people will reflexively shrink their hands.
When people smell the aroma of food, they instinctively feel hungry.
This is a conditioned reflex.
And this was also the main method used by humans in the old days to tame police dogs and other animals.
Can the zombies who also have conditioned reflexes be tamed in the same way?
Although he hasn't tried it yet, Dudian has great confidence in his heart.
"The way she is now is because of the message I sent out from my body, which made her think I was delicious, so she wanted to pounce and bite her.
But she won't bite a stone.
This doesn't mean that the stone won't send out messages.
But she received the information from the stone, and after analysis, she came to the conclusion that the stone could not arouse her desire to attack."
Dudian's expression was particularly serious, his eyes flickering slightly, thinking about ways to tame her through conditioned reflexes.
He knew that once he completed the taming, he could keep her by his side forever.
This is his last desire in life "If we mess up her information processing, change her conditioned reflex, and make her think that I am a stone, then she will not attack me."
Dudian frowned and thought, "In this case, we must first make her not attack me."
It seems a little wrong to react to blood again.”
The walking corpse's desire for blood is as instinctive as humans' desire for food.
Instinct is one of the hardest things to change.
He held his chin and pondered for a moment, and soon realized where his mistake was.

People in the old days used conditioned reflexes to tame police dogs, not to suppress the instinct of the police dog, but on the contrary, but to use some commands to replace what the police dog needed in its instinct.
"Use conditioned reflexes and add instructions to tame them."
Dudian murmured to himself and pondered for a moment.
He gradually understood that if he wanted to use conditioned reflexes to tame Hailisa, he must first establish order.
For example, feeding meals on time, prohibiting growling, etc.
Thinking of this, he sat down cross-legged and began to formulate a taming plan in his mind.
When he was halfway through the idea, his stomach growled with hunger again.
He immediately stopped and frowned.
He put aside the training plan for the time being, but his own survival became a big problem in front of him.
He raised his head and glanced at Hailisa.
His action immediately caused Hailisa's reaction.
A ferocious look appeared on her face again, and she roared.
Du Di'an was silent in his heart.
Could it be that he really had to lure her away first?
Once she is lured away, what method should be used to find her back?
While he was pondering in his mind, he suddenly caught a glimpse of slight cracks on the ground under the console in front of him. ground Dudian reacted suddenly.
He couldn't help but look at the ground under his feet and reached out to touch it.
Yes, the ground was not made of metal, but made of concrete.
Moreover, after more than three hundred years, the concrete here was in a sealed dry environment, like Cracks appear like molting.
Dudian became a little excited and couldn't help but want to pat himself a few times.
He should have noticed this a long time ago "We should have thought a long time ago that the ground cannot be made of metal materials.
In the world that people in the old days understood, the ground itself is as thick as the earth.
Coupled with a solid foundation, it is the strongest defense.
There is no need for metal materials at all.
On the contrary, If metal materials were used, the project would be larger, more time-consuming and more consumables, and the effect would be only slightly stronger.
The main danger at that time came from the ground, not the underground, and there was no deliberate fortification at all," Du Di'an thought to himself.
He quickly stood up and pushed aside the messy books and papers scattered on the ground, revealing the molten concrete floor inside.
There were no tiles on it.
Apparently, he was worried that the tiles would lock the moisture on the ground, causing the inside of the shelter to become wet.
Tide.
Seeing the cracked and fluffy concrete floor, Dudian did not hesitate and quickly dug it away with his hands.
His fingernails dug into the concrete, and with the force of his fingers, it felt like they were piercing into the soil, and he quickly dug out a handful of soil.
Seeing that there was hope, he felt happy, changed his position, and went to the corner of the vent in the room to dig the soil.
The ventilation duct was established here, which meant that this place might be closest to the outside.
In the rapid digging of the soil, he soon dug a deep hole.
He couldn't help but recall his life in prison, with a wry smile in his heart.
He seemed to be closely related to digging tunnels.
However, the situation this time is undoubtedly much better than in prison.
In prison, the sound of digging and the digging of soil have to be hidden, but here you can dig as much as you want.
While digging a hole more than one meter deep, he suddenly thought of Hailisha outside the door.
Once he crawled out along the passage, she would also leave here, and he had to keep her inside.
If you want to keep her, you need to close the door to the ruins.
But there are no valves inside the ruins gate.
The valves that cannot be opened and closed are all outside the ruins gate.
As for the mechanism on the console, he did not dare to touch it easily to avoid opening the door by mistake.

"Leave her here first.
After digging out, go around the outside of the ruins and see if there is a valve that closes the gate of the ruins."
Du Di'an immediately made up his mind.
Judging from the tragic scene in the ruins, he felt that the valve was there.
The possibility of being outside the gate of the ruins is still very high, otherwise, the people in the control room would not have starved to death here.
He crawled out of the hole, lifted the chair that had fallen to the side, and placed it half a meter in front of Hailisa's fingers.
Then he laid the ice-crystallized flesh and blood from his previously cut off left arm on the back of the chair and followed her.
The fingers are about the same height.
While he was provoking, Halisa bared her teeth and kept growling.
Dudian glanced at her, took out a dagger and cut his wrist, letting the blood flow down the back of the chair.
He stopped when half of the back of the chair was dyed red, and quickly strangled the wound to control the blood flow to stop the bleeding.
When he released the blood, Halisa's growl suddenly turned into a violent roar, and at the same time, a heavy gasp came from her nose.
Seeing that it was working, Du Di'an felt relieved, turned around and went to the hole, and continued to dig the soil.
He dug the soil very quickly.
After all, his physique was not comparable to that of ordinary people from the old days who were trapped here.
After a few minutes, he dug out a depth of three to four meters.
He felt that the height of the foundation should be about the same, so he turned to the side.
Plane away from the wall.
As he expected, when he dug to the ground under the metal wall, all he touched was soil, and he dug through it easily.
Du Dian dug along the metal wall and found that the thickness of the metal wall was half a meter long.
He couldn't help but secretly marveled.
With such a thickness, even if it was bombarded by missiles, it might not be able to destroy the ruins.
Soon, after he had planed through the metal wall, he immediately planed upwards.
After a few meters, he suddenly found that there was still dirt on top, and he could only continue to plan upwards.
More than ten minutes later, he dug a gap up from the other side of the metal wall.
When he climbed out of the gap, he suddenly found that he was on the ground, and he could vaguely see some wandering corpses around him.
During the two days that he was locked in the small room in the ruins, the tide of corpses that had gathered still had not completely spread and were wandering around here piecemeal.
Dudian let out a breath and slid down the dug passage.
The entire passage was like a "u" shape.
Outside the metal wall of the ruins, there was mud with a depth of more than ten meters, so it was not so much a "u" shape.
Rather, it’s a reverse “j” shape.
After sliding into the bottom of the passage, Dudian quickly crawled back to the room.
Seeing Hailisa still yelling outside the door, he breathed a sigh of relief, then picked up the daggers and other objects left on the ground, took out the corpse powder, and applied it again On oneself.
After the application was completed, he took a short rest and regained some strength, then quickly dug out along the dug channel and climbed to the ground outside.
After reaching the ground, he took a look around and found a large scattered stone.
He carried it to the entrance of the passage to prevent any zombies from accidentally falling in and crawling into the control room.
After doing this, he found the right direction and quickly came to the slope passage on the other side of the ruins.
He saw that there were still walking corpses wandering inside, but the number was much smaller than before.
He held the dagger tightly and walked into the passage.
Some walking corpses that I met along the way immediately moved away after seeing him, as if they were disgusted by the smell on his body.
Dudian breathed a sigh of relief and walked straight down the passage.
Suddenly, he saw a strange zombie lying on the ground in the corridor deep in the slope.
Its body was like a lizard, its tongue stretched out extremely long, but its face looked like a human. , but the cheeks are covered with scales, which is extremely weird.
Together with the mouth that is split to the base of the ears and the mouth full of sharp teeth, it is extremely ferocious.
When Dudian appeared, the strange zombie immediately turned its head and looked at him.

Dudian's face changed slightly.
In his weak state at the moment, it was too difficult to deal with such a strange zombie.
Moreover, he was worried that the sound of fighting would distract Hailisha.
She was completely unaffected by the zombie powder.
In her current state of complete corpse transformation, she could easily tear herself apart.
The lizard-like strange zombie stared at him with a pair of amber eyes, and the cheeks under the split mouth moved slightly, as if it was sensing something.
After a while, it slowly crawled to one side, spitting out its contents.
With his forked tongue, he roared twice in a demonstration at Dudian.
Dudian looked slightly startled, and soon realized that this strange zombie probably thought of himself as another high-level zombie.
After all, the hidden corpse powder was mixed with the smells of different high-level zombies.
And it can also be seen from its behavior that if it recognizes itself, it will probably pounce on it immediately, and there will be no such behavior that reflects thinking.
However, it can also be seen from this point that the walking corpse does not seem to be Completely unconscious creatures will still have some different reactions when they face the same kind.
Dudian took a deep look at it and walked slowly around from the other side of the passage, always alert to its attacks.
The lizard-like zombie did not pounce, but faced Dudian, demonstrating and roaring from time to time.
Dudian quickly moved outside the ruins.
While paying attention to the lizard-like zombies, he looked inside the ruins.
From here, he could see the door of the control room deep in the ruins from a distance.
Hailisa threw herself there and let out a low roar. , obviously, the smell of blood flowing on the chair stimulated her more strongly than the stimulation of his physical appearance here at this moment.
Seeing that she was not attracted, Dudian breathed a sigh of relief and immediately looked around at the gate of the ruins.
After scanning several times, he still didn't see any device or secret valve mechanism, only the iris-scanning device.
Could it be said that opening and closing are controlled by this organ?
Such a thought flashed through his mind, and he tentatively stepped forward to open the iris-scanning device and clicked the button inside.
A red light suddenly shot out of the instrument and swept across his eyes.
Soon, the electronic synthesized sound he heard before sounded from inside: "Scanning completed, identity verification, whether to close the shelter?"
Dudian was startled, but he didn't expect that it was really like this.
He immediately said in English: "Yes." boom As soon as he finished answering, there was a slight trembling sound at the ruins gate, and soon the sound became louder and louder.
The metal gates that had been retracted to both sides of the ruins gate were pushed out again from the inside.
The ground shook slightly during the push, and the huge movement immediately attracted the attention of the zombies wandering in the passage behind Dudian, who rushed here immediately.
Dudian looked into the ruins, and saw Halisa turning her head and noticing this.
At the same time, her palm seemed to be struggling to pull out of the small door of the control room.
"Damn" Du Di'an felt a little anxious, "Hurry up and close it" After struggling for a moment, Hailisa pulled out the arm stuck in the window, roared, and rushed towards here, as fast as lightning, like a thunder leopard.
Dudian's pupils shrank.
Bang The gate to the ruins closed with a bang.
At the same time, Dudian felt the door shake slightly, and some dust on the door fell off.
Seeing this scene, Du Di'an was secretly shocked.
This is her current power.
Hoho At this time, the zombies coming from the passage behind Dudian also fell on the giant door of the ruins, letting out waves of wailing roars.
Dudian immediately withdrew from the group of corpses.
Although there was hidden corpse powder, there was still a risk of being exposed if the distance was too close.
He closed the metal box on the ruins and slowly walked back, preparing to leave the passage.
But not long after he walked out, he felt that he was in trouble.
He saw that the strange zombie from before was also attracted by the sound and rushed here.
The distance between him and him was only about three or four meters.
This distance was as high as that of a high-level zombie.
Perceptually, it's a bit too close.

Moreover, Dudian saw that there seemed to be some fierce light in its eyes.
Just as he was preparing for a bloody battle, suddenly, a rough man's voice came from outside the ramp in front: "Boss, there seems to be a cave here.
Do we want to go in and take a look?"
