Alien beasts, as the name suggests, are naturally creatures infected by viruses after the cataclysm.

Strange secondary viruses can not only act on the human body, but also have some infectious effects on the animals and plants on the earth.

There are even unexpected changes in some organisms.

In Timeline 659, after a long war, the Terrans finally overwhelmed the undead and the alien beasts and regained the position of the master of the earth.

It is precisely because of the war on the earth that the human race was able to breathe and develop, and it was only a hundred years later, that is, the emergence of the 659 generation, that the human race reached level 2.0 civilization.

As if sensing the doubts in 659's heart, Bai Donggu, who was walking in front, explained.

"Naturally, these residents of the lower city can't deal with the alien beasts, after all, most of the people who set up stalls in this Exchange Square are ordinary people."

"Ordinary people?"

Hearing that the conjecture in his heart was confirmed by Bai Donggu, 659's heart became more and more puzzled.

"Since they are all ordinary people, where do these animal skins and bones come from? Looking at the way they sell, it doesn't seem to be the first time they have done this kind of business. ”

659's gaze swept over the nearest booth to the trio, on which were placed two small dark bottles, the rough wick peeking out of the mouth of the bottle, and the orange-yellow flame pulsed slightly on the mouth of the bottle, illuminating the small stall.

Since there are no lights in Exchange Square, almost every booth is equipped with similar lighting, but most of them use a small light fixture connected to a simple battery.

The stall owner keeps the light bulb bright by shaking the generator in his hand.

While this kind of lighting fixture, which generates electricity by hand to power the fixtures, does not illuminate a large area, it is more than enough to illuminate a small area on the stall.

Compared to the brightness of other stalls, the small stall in front of me, which uses oil lamps as lighting tools, is much more special.

Of course, it's particularly dark.

Even though the light wasn't so good, 659 could see what was stacked on the stall.

What caught his attention was a triangular skull slightly larger than a human head in the middle of the stall, which in shape was supposed to be a carnivorous animal infected with a secondary virus.

There was a deep wound on the face of the skull, which looked like it had been slashed with a sharp weapon.

The bones of this kind don't look like they were picked up by the inhabitants of these dungeons after a natural death.

"That's right, most of these are the families of the Revenants, they don't have the ability to hunt alien beasts, these beast bones and skins are all hunted by their families."

"Oh, it turned out to be a family member, so it makes sense."

659 nodded in realization, didn't stop in front of the stall with the triangular skull, and rushed forward a few steps, trying to catch up with the white winter bone in front of him.

But at this moment, a small pale and slender hand grabbed the corner of 659's clothes, causing his body to slam suddenly.

"Big brother, do you want to buy this skull......"

The immature children's voice came from behind 659, and it was impossible to distinguish the gender of the other party just by listening.

"Is this stall owner still a child?"

659 thought to himself and looked behind him.

The stall owner selling triangular skulls was draped in a wide, tattered linen tunic with a huge hood that completely obscured his face, if you didn't look at the tugging garment

With the pale arms of the horns, 659 really can't judge the age of the other party from the appearance.

"I don't need to, thank you."

Although he was a little curious about the stall owner's situation, there were more important things to do at the moment, and he was not like 173, who would be distracted by some inconsequential things.

After hearing Zhang Heng-659's refusal, the stall owner, whose body was covered by a linen jacket, trembled obviously, but the thin little hand did not show that it was loose, but pulled it tighter.

"Please, big brother, buy this skull, I beg you......"

There was pleading and some trembling in the childish voice.

This time, 659 listened carefully, and could vaguely tell from the voice that the other party should be a little girl.

"Isn't it possible that the trading rule here is to buy it at a glance? I told you I didn't need this skull. ”

The silver-white mechanical left arm stretched back, grabbing the slender wrist lightly and heavily.

659's mechanical arm is the most advanced mechanical artifact in his timeline, connected to the energy core on his left chest, where the Jue ion shield generator and the ball lightning generator are installed.

Although it is not the kind of mechanical arm that is known for its strength, it is definitely more than enough to break the pull of a little girl.

"Hmm, it hurts!"

Sure enough, 659 only used two fingers, and the strength was not light or heavy, and the little girl quickly screamed in pain, but the pain was painful, and the thin palm was still dragging the corner of 659's clothes, and there was no intention to let go.

"What's wrong?"

Bai Donggu, who was leading the way in front, noticed that the person behind him didn't seem to be following, and immediately looked back, only to find that 659 was looking at him with a strange face, and the expression on his face was like a guest who blamed the host for not treating him well.

"General Bai, in your trading rules, is there still a forced buying and selling?"

"Why?"

Seeing that 659 didn't seem to be joking with himself, Bai Donggu immediately turned around and leaned towards the stall.

"White ...... White General ......"

The little girl who was tugging at the corner of her clothes and didn't let go saw Bai Donggu walking towards her, she called timidly, and then let go of the corners of her clothes.

"Xiaoyi? Why are you here alone? Where's your dad? ”

Bai Donggu seemed to be a little familiar with the little girl, and immediately called out the girl's name after getting closer.

Hearing Bai Donggu's inquiry, the girl reached out and retracted the hood covering her head, revealing a fairly clean little face.

"Daddy, Daddy, he'......"

The little girl was about to say something, but suddenly she closed her mouth again, and her big watery eyes looked around from side to side, and she stood in silence.

At the same time, 659 also clearly felt that there seemed to be a few more pairs of eyes around him, sweeping towards the little girl's stall as if they were nothing.

"Eh, why don't you speak? Tell me, what's wrong with your dad? ”

173 also came over at this time, and when he saw that the little girl suddenly fell silent, he subconsciously asked.

But no matter how much he asked, the little girl seemed to have lost the function of speaking, and was pestled in place like a stake, and became completely dumb.

"What a clever little girl......"

659 raised an eyebrow and commented in his heart.

The little girl in front of her is obviously not simple, but there are many people around, and if she really talks about it in this Exchange Square, I am afraid that someone with a heart will catch some rumors.

Bai Donggu was obviously aware of this, the light in his eyes flowed slightly, and he whispered softly.

"Come with us, find a place where you can talk."

Hearing what the white generals said, a sweet smile appeared on the little girl's restrained face, nodded her head vigorously, squatted down, and quickly cleaned up the stalls on the ground.

The little girl's booth wasn't big, and there wasn't much cargo on it, except for the larger triangular skull that 659 had seen at the beginning, all that was a few fist-sized knuckles and four fangs the size of an adult's index finger.

It seems that the triangular head is the remains of some kind of snake.

The little girl leaned down to blow out the flames on one of the black bottles, carefully plugged the bottle, and then began to clean up the bones stacked on the stall.

Despite her small size and the obvious lack of strength in her hands and feet, she was able to gather all the goods in the entire stall in less than a minute, and firmly fastened the mouth of the cloth bag.

After doing all this, the little girl hurriedly squatted down again, carefully picked up the remaining black bottle on the ground, blew out the fire on it, and put it away.

The already dim environment lost the lighting of the flames and became darker, and the little girl in the linen ragged dress was like a little mouse busy up and down in the dark, finally finishing the little belongings on the stall.

The bag full of bones and the skull, which was a few points larger than a human skull, were almost as high as the little girl.

But the girl still carried the bag on her back, and did not have the slightest intention of asking for help.

"I'll do it."

173 grabbed the cloth bag on the little girl's shoulder and wanted to share the burden for her, but after his eyes met the little girl's face, he unexpectedly noticed an obvious precaution in the other party's eyes.

"Don't worry, General Bai is here, he won't rob you."

659, who was holding his hands on his chest on the side, said lightly, and glanced at Bai Donggu with his eyes.

Bai Donggu didn't seem to expect 659 to suddenly say this, nodded subconsciously, and said with some comfort.

"Xiaoyi, it's okay."

Hearing Bai Donggu say this, the little girl let go of her little hand that was gripping the cloth bag, wrapped the clothes on her body tightly, so as not to drag it to the ground, and obediently followed behind the three of them.

"Let's go, White General."

659 spoke, his head tilting and glancing around.

His glance was obvious, obvious enough to make anyone in the shadows aware of his presence.

The creaking that had been filling the surroundings came to an abrupt end, and 659 understood that it was the peeping stall owner who stopped the joystick of the hand-cranked generator in a panic.

Fortunately, most of the light bulbs were equipped with batteries at the other end, so this change did not make the light in Exchange Square disappear instantly.

However, under the glance of 659, those prying eyes were like bats that had met the sun, and they hid in a panic, and the trading floor was still quiet, as if nothing had happened just now.

When the four of them disappeared into the passage at the other end of the square, the quiet square resounded the not-so-bright creaking of the motor shaft......
