The fire was soaring, and Lu Yunxi did not sleep peacefully.

She tossed and turned, and it wasn't until the middle of the night that she could fall asleep.

Not long after falling asleep, Lu Yunxi felt that there was an extra person beside him.

In a trance, she struggled to open her eyes, confused and unable to see clearly, just by feeling, she seemed to be able to touch a person sitting next to her.

The man was wet, and he was stretching out a pair of hands and gently resting them on Lu Yunxi's shoulders.

Lu Yunxi immediately smelled a strong fishy smell.

She was somewhat familiar with the smell, and her whole body reflexively tensed, and she soon realized what it was - it was a merman!

Lu Yunxi wanted to exclaim, but her mouth seemed to be blocked, and she couldn't shout a word.

Then, she heard a sound ringing in her ears.

The voice was next to Lu Yunxi's ear, gently brushing by, as if someone deliberately stroked her earlobe with his fingers.

"We are all system people. ”

Hearing this, Lu Yunxi was instantly stunned in place, motionless, and a cold sweat broke out on his back in an instant.

Immediately after, everything in front of me became clear.

In the darkness, there was a man sitting beside her couch covered in water.

It's just that that he is no different from an ordinary person.

Lu Yunxi stared at the man's eyes, frightened, "What did you say?"

"You're also from the system, right?"

Lu Yunxi was stunned when she heard this.

The man lifted the kaftan from his arm, revealing the faintly visible tattoo on his arm.

Lu Yunxi looked at it for a long time before he recognized that it was a number, and strangely, the number was written in English: ze

o。

"Zero?"

Lu Yunxi raised his head in confusion and stared at the man's blood-red eyes.

The man slowly lowered his sleeves, lowered his eyes, and nodded slightly, "I was the first person to come into this world through that system. ”

Lu Yunxi stared at the man blankly.

Let's call this person zero for the time being.

Zero showed a bit of desolation on his face and told his story.

He was originally an engineer in Huaguo, and one day when he was inspecting the construction site, he accidentally fell, thinking that he was dead, but he didn't expect to wake up but he had already arrived in this world.

At first, like Lu Yunxi, he thought that the system valued his talent and brought him to this world, buying life with silver, and he did rely on his own ability to live in this world for a few years.

However, the good times were short-lived.

Soon after, he married a woman and gave birth to a son, who turned out to be an alien pupil.

Hearing the word 'different pupils', Lu Yunxi's heart 'chuckled' and became nervous.

"After the child was born, his mother died in childbirth. The child was tormented by the strange stares around him, and died before he was three years old. It was also from that time that I learned that another son of a different pupil was born in the capital, so I rushed to the capital. ”

The son of the different pupils in the capital in Zero's mouth is the child who died in the fire.

Zero tried every means to get in touch with the child's mother, and after inquiry, he learned that she was also a member of the system!

Hearing this, Lu Yunxi broke out in a cold sweat all over his body, and his lips were already shivering uncontrollably.

She couldn't believe what she was hearing.

In this way, in this world, there is not only a person who is a system, but also the zero in front of him, and the woman who gave birth to another son with different pupils.

Moreover, it seems that as long as it is a person from the system and a marriage in this world, the final birth will be the son of a different pupil.

"Is it just the two of you?"

The man pursed his lips and shook his head slowly, "The number on that woman's body is already thirteen. ”

"Thirteen?"

Lu Yunxi was surprised.

She lifted her sleeves and looked at it for a long time, but there was no half of a tattoo behind her, and there was nothing on her smooth jade arms.

"Why didn't I?"

Lu Yunxi looked at Zero in surprise and said in a deep voice.

"Because, the system hasn't given up on you yet. ”

When Lu Yunxi heard this, she half-understood, frowned, and stared at Zero.

She didn't understand what Zero meant by not giving up.

"The system gave up on me because I couldn't earn silver two more to buy life in the second half of the year. The system also gave up on Thirteen, because after her child died in the fire, she collapsed and was unable to complete any task given to her by the system. ”

Lu Yunxi's whole body was cold, and when he thought that he had almost failed to complete the task several times, his heart was also up and down.

"When the system gave up on us, it turned us into mermaids. ”

This news is undoubtedly even more thunderous.

"Sharks?"

Lu Yunxi looked at Zero in surprise.

Zero's eyes of despair scanned her body and nodded painfully, "Yes." Shark people. ”

After the system abandoned Zero and Thirteen, one day, the system sent out a task to recall them.

Let them go to the sea, ordinary a wooden boat.

The two of them got on the boat, but they both fell asleep, and when they woke up, they became mermaids.

Now, they only return to their former human appearance in front of each other, and the rest of the time they are the same as sharks.

"Why?"

Lu Yunxi was surprised and panicked, and asked loudly with mixed feelings in her heart.

Zero's face was even more weird, he lowered his head, and gently rubbed his right hand twice, "According to me and Thirteen, they may want to use the merman to destroy this world. ”

Lu Yunxi heard it even more in a fog, and she didn't know what to say.

Zero stared at Lu Yunxi's eyes, his gaze was gloomy and firm, and he said something that Lu Yunxi couldn't accept.

"Our world is about to disappear, and the people in charge of the system want to create a whole new world. They found the world in time travel and sent us to this world first to see if we could fit in. ”

"In that case, why destroy the world?"

"Because, if we can adapt to the world, they will keep sending new people in. In this way, the world will be saturated, and if the original people of this world do not disappear, then all of our people will not be able to enter this world. ”

Lu Yunxi instantly understood what he meant.

This is the simplest law of conservation of mass in physics.

All the substances in this world have a total amount, and if someone has more possession, some people will possess less.

If the system wants to transport the people from Lu Yunxi's world, it must let the people in this world make more living space for them.

To put it bluntly, this is the legend – one life for another.

Lu Yunxi gasped, stared at Zero, word by word, and asked in a deep voice, "Will you destroy this world?"
