Stone has always been an important resource in this world, because only stone can build strong and powerful defensive functional buildings, in the past, people could still find easy to mine stone bare ore, but after a long period of mining, now human beings can only obtain stone by digging huge mountain rocks, which also makes people start to use them from different angles.

One of the best of them is the Romans of the last era, who built the Colosseum and the Golden Colosseum, which are still amazing engineering marvels, and their aqueducts and aqueducts are built by their own efforts and wisdom.

From stone mills, stone mortars, stone tables and chairs that are closely related to daily life, to exquisite stone carvings and precious gem crafts, stone has been silently integrated into the civilization of this world when the human civilization of the imperial era is further advanced, and a variety of stones will replace wood and gold as the most important resources of human civilization.

But now, for some poor people, stone is the source of their suffering, and it is also the reason why they are lucky to survive.

The Cult of the Damned did not want to use shoddy functional buildings as their headquarters, and their testing grounds, council halls, elders' quarters, assembly halls, high-level undead quarters, and the largest mausoleum under construction were all built of stone and Roman cement, and the high-level necromancers enslaved a large number of undead as builders, and the scholars who took refuge in the Cult of the Damned were responsible for providing the drawings.

The stones needed to build this huge project came from a quarry dozens of kilometers away, where tens of thousands of living humans were forced to work as coolies, and there were no stone veins in the usual sense, but the scholars of the Cult of the Damned God had the idea of a rock layer buried 20 to 30 meters underground, so this karst landscape was completely created by man.

Not far from the quarry is the Stonemason's Camp and the Carver's Camp, which are also imprisoned by human slaves, but they are all craftsmen with stone processing skills, and the stone of the right size will be sent to the Sculptor's Camp to be carved into gargoyle statues, while the rest of the stone will be polished into the standard stone bricks required by the drawings in the Stonemason Camp to build the headquarters of the Cult of the Damned.

These people should be the last survivors of the natural disaster occupied area except for the army, and by the time the war has reached this point, those who can escape from the enemy-occupied area have already fled to a safe place, and those who cannot escape have either become raw materials for the natural disaster or become slaves.

In fact, if it weren't for the stonemasons who repeatedly said that the stones mined by brainless corpses did not meet the standards for producing stone bricks, and in the consistent style of the Cursed God Cult, these tens of thousands of human slaves would not have been left behind at all, and they would all be used as raw materials for the production of the army of the undead.

Although these stonemasons captured by the undead disaster saved tens of thousands of human lives in their own way, they were powerless to change the living conditions of these human slaves, and could only watch them struggle to survive in the extremely harsh quarry pits.

Knock woke up in a violent cough, and found that she had woken up not in the cell filled with the stench of corpses and the wails of the souls (the subject's holding cell), but in a small, dimly lit room, a place she was unfamiliar with.

It was located in a hollowed-out tunnel, and the slave masons dug out some caves on both sides of the tunnel, and simply paved them with gravel and mud as a place to live, but the conditions of this dwelling were very poor, not to mention cloudy and cold, and the air was filled with a lot of dust, and the slaves who lived in it lived like burrowing rats and ants, not humans.

The Undead Scourge doesn't care about how well these humans live, it only cares about how many stones these human slaves can mine, and the overseers of the Cult of the Damned here torture these poor people in various ways, forcing them to do intense work until they die of exhaustion.

In the beginning, the slaves here were mainly men and young men, but due to the further escalation of the war, the army of the Scourge could no longer find suitable labor as slaves, so they had to send the elderly, women, and children to this flesh and blood mine.

People die every day, and those who aren't tough enough and not smart enough to hold out don't last long before they're pulled out of the mines by hideous vehicles loaded with corpses, and the undead scourge always finds a place to catch a bunch of wretched worms to make up for the number of slaves in the quarry.

Yin Wensu and Youshi, who are not yet thirteen years old, are among the slaves captured by the undead natural disaster to replenish the number, but these two children live longer than many adults, don't think that this is due to their status as children, in this disorderly place, the young are the lowest level of the food chain, and many of them can't even hold out for a week.

That little ghost named Yin Wensu has a very good physique, he can swing a heavy hammer to chisel stones like an adult, not only that, but he also knows a lot of knowledge about surviving in a harsh environment, and people who live for a long time are not willing to offend this little survival manual.

It seems that Yush, who looks younger, survived purely because of luck, and many of the guys who wanted to snatch the child's food ended up inexplicably unlucky, and some even lost their lives, so everyone was even more reluctant to provoke this evil imp.

"Yo! You're awake! How do you feel now? Can you speak? Do you want to drink water? ”

After Yin Wensu saw Dongdong open his eyes, he walked in front of the little guy with a fragment of a clay pot that could hold water.

This morning the undead threw a group of captured humans into this living hell, Yin Wensu and Youshi found that there was a very special child in this group of people, saying that she was special because when she was thrown in, the girl was still in a coma and her body was full of scars, obviously she was brutally beaten and tortured, although the undead now catch everyone, but such a half-dead child is usually killed directly, driven by curiosity and compassion, they brought Dongdong back here.

Dongdong didn't mean to drink water, she just stared blankly at this strange little space, and tears began to flow out unconsciously.

"Hey, hey, hey! Why are you crying? I know it's unlucky to be caught in this place, but it's a lucky thing to survive! So don't cry! A good boy should live strongly! You're a good boy, aren't you? ”

These words are said by a child who is two or three years older than Dong Dong, which will make people feel a little awkward and funny, but Yin Wensu's words of coaxing the child have an obvious effect on Dong Dong, making her almost cry to hold back her tears.

"What an obedient child...... In this place, it's useless to just cry, oh! You stink right now. ”

Of course, the smell on Dongdong's body is not good, and anyone who has been locked up with a large number of corpses for half a month will have a strong rancid smell on his body, so none of the slaves who were sent to this place together were willing to approach her who was unconscious, except for Yin Wensu and Youshi.

"How? Can you still walk around now? If you can get up, follow us, and we'll take you somewhere. ”

Knock can walk, although it will make her body hurt a lot, but it is nothing to her, the little one sat up tremblingly, and then stood up little by little with his hands against the wall, like a toddler.

Yin Wensu on the side didn't want to go up and help her, he just looked at the girl who had just been picked up by them with approving eyes, Yin Wensu and Youshi had also rescued children of their age before, but they were either too dependent or untimely childish, in short, none of them could survive, and Yin Wensu and Youshi couldn't help them.

To survive in such a place, you have to understand that tears and prayers are useless things, and this girl did very well, except for some tears at first...... Uh~ Okay! She is still unconsciously shedding tears.

But she didn't scream in horror, she didn't have a look of utter despair on her face, and apart from her red eyes and clenched lip biting to show that she was still terrified, she was generally better than most of the adults who had been caught here.

The jailer in charge of monitoring this area is a priest of the Cursed God Cult, and he will not patrol his jurisdiction at all, because the slaves who tried to escape before were torn to pieces by the gargoyles patrolling the sky, and the laborers who knew that they had no way to avoid these air killers could not afford to escape, Yin Wensu and Youshi took advantage of the jailer's carelessness to take the girl to the depths of the abandoned tunnel.

Dongdong, who was injured, walked very slowly along the way, and the two boys had to stop from time to time to wait for her to follow, but none of them went up to help her, and Dongdong did not ask for help, and the three children entered a very hidden gap.

This gap can only be climbed into by small children, and the size of adults will be stuck in the middle, and after Dong Dong climbs into them, he finds that this crack is connected to a small cave, and there is a dark river with gentle water flow in the cave, and the air is much better than outside.

"You have to be careful, the bed of this dark river is very slippery and the deeper you go, and we have fellow drowning in the river."

There was a child who knew how to run through the river and wanted to escape through this dark river, but when Yin Wensu Yushi found out that he was not there and hurriedly came here to look for him, he only found the body of the other party washed up by the river, and he drowned himself.

Although there are a lot of water sources in the tunnel, but the quality of those water is generally not good, often more than a dozen laborers share a water source, even if it is clean and good water, over time it will become turbid and inferior water, in fact, as long as someone cleans it well, the water source will still become clean, but in this precarious situation, who else would think about cleaning up the water source polluted by debris?

Yin Wensu and Youshi have a lot of people who know about the possession of a living water, but they can't get through that narrow gap at all, so they can only envy, and for the hard workers who have given up hope, the value of a living water is not great, anyway, there is no shortage of water here.

Xiao Maoyu originally didn't like water, and when he was in the research institute, Colonel Chu even coaxed and tricked him to get used to taking a bath, but now after seeing the water, the little guy couldn't wait to jump in and jumped Yin Wensu and Youshi on the side.

The water of this underground river is very icy, and Dong Dong, who jumped into it, suddenly felt the biting cold, and the stimulation of the cold water on the wounds on her body made the feeling called 'pain' hit Dong Dong's consciousness like a flood, it was really, very painful.

At this time, normal people would scream and rush to the shore, but Dongdong was floating quietly in the water, she could feel that her limbs were gradually losing sensation with the cold penetration, and there was a feeling of breathlessness in her chest.

Obviously he felt uncomfortable, but the little guy had no intention of leaving the river.

Because of the incredible ability of missionaries in this world, the Cult of the Cursed God was very cruel to Dongdong's 'experiments', and they even prepared several bottles of Fountain of Life that they didn't know where to get to prevent the test subjects from dying due to excessive research.

Stress response is a self-protection mechanism gradually formed by organisms in the process of evolution, Mao Yu has a simple evolution, primitive structure, and there is no system that only such complex organisms have, so there is no such thing as Dongdong.

The little guy has been living as a human for nearly two years, in the past two years, she has initially formed some simple stress reactions through the observation and imitation of the people around her and her own experience, at first she was very slow to even feel hot and cold, and even fell asleep in the cold wind of midwinter, but not long ago Dong Dong has been able to subconsciously take the initiative to keep warm.

It is unimaginable for a Mao Yu to get what humans are born with, but all this difficult evolution has been destroyed in just half a month of experiments.

When she can't avoid any external injuries and can only passively accept the torture, the existence of the stress response is meaningless.

But when she went back to the situation when 'a simple soul could not control a complex body', Dong Dong had a different feeling, she felt as if she was wrapped in a heavy nasty shell, which made her very, very uncomfortable.

That's why she wanted to jump into the water and let the icy river wash away all the things that made her uncomfortable, whether it was those horrible memories, horrible sounds, or nasty shells, all of them! All of them!

"You idiot! Don't die! ”

Yin Wensu shouted angrily, and then jumped into the water with Youshi, who had not spoken, and dragged Dongdong ashore.

"I thought you were strong! I didn't expect to be a fool! No matter what, there is hope for hard work, and if you die, there is nothing! You...... What are you doing? ”

Before Yin Wensu's tirade was over, he felt that the other party's cold hand that should have been unconscious before breaking free from his control.

Dong Dong, who had just been dragged ashore, staggered to his feet and walked towards the river again.

Mao Yu, who was frozen by the river, had only one thought left in his head.

'Wash them all away...... Nasty Stuff...... All...... Wash it clean......

Clean, carefree, blissful ...... But how could such a thing happen?

Dong Dong was pressed to the ground by two boys who were also not lightly frozen, Yin Wensu felt as if he was in the third type of contact, and he couldn't even figure out her behavior pattern.

At first, seeing that she was silent and endured the pain to follow up, Yin Wensu also felt that she should be a silent and strong girl, but not long after he came to this conclusion, the strong Dong Dong jumped into the river......

Dong Dong really doesn't mean to commit suicide, even if it is a stone to hang, Dong Dong will not have the idea of suicide.

She really just wanted to wash herself thoroughly.

"What do you want to do, you idiot? If you give up your life so easily, your parents will be sad! ”

Yin Wensu could probably guess why this girl committed suicide, the bruises and cut scars on her body are obvious clues, more than ninety percent of them may have collapsed because of torture, in a sense, he did guess correctly.

"Mom will be sad...... Mommy ......"

Knock Dong's struggle to get back into the river gradually faded, and the little one's eyes regained some clarity.

The word mother carries too much weight in her heart.

Heavy enough to easily pull the crumbling Dong Dong back from the death line of his will.

"That's it! It's finally gone! Who the hell are you? Dead girl who wants to jump into the river! ”

The relieved boy let go of his restraints and asked Dongdong, who was slowly getting up, in a complaining tone.

"I ...... I'm not a person, I'm Mao Yu...... I am...... The Great Light? I do not know...... What I am. ”

When I was in the MC world, the little guy could not hesitate to declare, 'I'm Mao Yu!' ’

When at the Frontier Fortress, the little one can hold his head up and proclaim, 'I am the Light of Greatness!' ’

But now, the little one didn't know how to answer this question, she had more than one answer here, but she couldn't answer any of them.

"Alright! I get it! Are you a psychopath? ”

Yin Wensu, who was panting evenly, said to Dong Dong very seriously.

"Neurotic?"

Xiao Maoyu tilted her head and repeated, she didn't know what the word meant.

"Ancestral neuropathy, specializing in the treatment of old Chinese medicine."

The boy nodded in explanation.

“……”

Although he didn't understand what it meant, Dongdong did feel that he was being bullied again.

The little one's eyes were red, and he was obviously going to cry again.

"What's your name?"

At this time, Yush, who had just pressed Dongdong from the other side, spoke.

His voice sounded a little inorganic, making the little one forget to cry for a while.

"Knock Knock ......"

Isn't that a good answer? What was going on with that just now? ”

Yin Wensu wanted to laugh a little, but the temperature of this dark river cave made the boy a little unable to laugh, and his teeth were fighting.

"Who are you? You're just knocking knock! Throw aside all those messy identity nicknames! Is this kind of question still to be entangled? ”

So, he asked again in a louder voice.

"Now, answer me! What are you?"

"I'm Knock Knock! It's a neurosis! ”

Xiao Maoyu replied very quickly, and then added very seriously.

"This is what you said, big sister......"

Yush twisted his face to the side, his shoulders shaking unnaturally.

Yin Wensu held his head with his hand, he was thinking about which planet this girl on the other side came from.

"Listen up! You are who you are! Throw all the mess away! Go back to me again! Who are you! ”

The roar of the 'big sister' made Xiao Mao Yu's stupid head return to normal operation.

"I'm Knock Knock."

That's right, you're Dongdong, your scientific name...... Mao Yu.
