The years I spent picking up garbage to eat in another world

Xiao Yang remained silent and walked slowly.

Suddenly, Mary grabbed his sleeve and stopped at a shadowy corner, with an arc of electricity bursting out of her golden hair.

Xiao Yang followed her line of sight and finally understood her anger.

In the corner, two slender figures leaned against the wall, hugging each other and trembling.

As if they felt the gaze of others, they trembled more violently, so that the broken hoods on their heads fell off, revealing a head of silver-white dry hair.

Wack's heart trembled.

It's broken.

The hood slipped off, and Xiao Yang finally saw the two clearly. This is a pair of twin girls with delicate faces. They must be beauties in the future.

But this is not the point. The strange thing is that they each have a pair of fox-like ears.

Just like Mary!

Xiao Yang glanced at Mary's furry rabbit ears, thinking.

"I want these two girls, remember them."

"Fuck, let them go."

Wak slapped the servant hard and shouted angrily.

The servant was also confused. He was just a salesman. What did he have to do with it? However, looking at Wak's cannibalistic eyes, he had to swallow the bitterness in his heart.

"Boss Xiao, this is just an accident. These sub-humans were captured from other cities and have nothing to do with us."

Wak explained hurriedly.

Who would have thought that Xiao Yang had a powerful sub-human by his side? It would have been better to hide the twins earlier. It would be bad if the other party was angered because of the two slaves.

However, Mary was in no mood to pay attention to him at all. She directly cut the chain with a knife. The deep and cold knife light made the human traffickers around tremble.

"Oh? Sub-humans? Are there many such cases in other cities?"

"Well... this... um, some beautiful sub-humans are very popular in other cities."

Wak glanced at Mary, his eyes were a little evasive, and he said it more tactfully.

In fact, because of the difference between the sub-humans and ordinary humans, they have always been rejected by ordinary humans, and even called hybrids, thinking that they are not pure humans, but aliens.

But because of their slightly furry features, beautiful sub-humans are very popular in the slave market and become the focus of human traffickers.

Such sub-humans can be sold at a high price in the market. This pair of twins is actually the bottom of Wack's box.

As for how the sub-humans appeared, this is not something Wack can know.

Xiao Yang saw the unnaturalness in Wack's words, so he stopped entangled in this question. He believed that Mary would give him an answer in the future, so he laid his cards on the table.

"Okay, I won't waste time with you. Do you have any special talents here? For example, those who can read and count, repair machines, build houses, or have other specialties. I want the kind that can work, not vases."

Recruiting people, technical jobs, this is Xiao Yang's main purpose of coming here.

The talents in Keer Town are too scarce, and they are all illiterate. He wants to see if he can get some talents out of the slave market. After all, human traffickers always have more channels.

"This."

Wak was somewhat confused and embarrassed. This was the first time he heard of such a request from a customer. In the past, men who came here would first look at their appearance, then their measurements, and finally their personality.

Xiao Yang didn't care about his mess. He turned around and spoke loudly to the numb crowd in the basement.

"Do you see the light outside? Do you want to be free? Now I'll give you a chance."

"Tell me. Does anyone here know what acceleration is? Does anyone know how to solve a quadratic equation? Or does anyone know what water is made of?"

"Whoever knows the answers to these three questions, stand up boldly! As long as you can answer any of them correctly, I will give him... freedom!"

Xiao Yang asked three questions.

These three simple math, physics and chemistry questions on Earth, which even junior high school students can answer, have become a natural barrier that can determine fate.

Only with knowledge can you have freedom.

As soon as the questions came out, a long-lost riot broke out among the slaves, and they talked about it.

However, immediately afterwards, everyone was silent, with endless unwillingness and loss in their eyes. It's not because of numbness to freedom, but because they can't even understand these concepts.

Half a minute later, the basement was still silent.

Xiao Yang was a little disappointed.

"No?"

"If not, forget it, let's go!"

Xiao Yang was also trying to make a play, and when he saw no one answered, he shook his head and turned to leave, not planning to stay any longer.

It seems that the civilization degradation of this world is much more serious than he imagined, and there is still a long way to go in the future.

"Sir, please wait a moment!"

Just as Xiao Yang was about to leave, a chain clattered, and a weak voice behind him called him.

This was a woman with disheveled hair, pale and covered with mud, but still with a regular face. The woman was wearing a fluffy white coat, with mottled blood on her body, and her figure could not be seen, but she seemed to be an evolver.

She staggered and wanted to come over, but because the chain was not long enough, she fell to the ground instead. Anyone could see her weakness.

However, in the eyes of everyone at this moment, the figure of this woman was so tall. She trembled and climbed up again, and answered in a weak but thunderous voice.

"Acceleration is...the ratio of the change in velocity to the time it takes for that change to occur."

"A water molecule...is made up of one oxygen atom and two hydrogen atoms."

"When Δ≥0, x equals..."

The woman's voice was intermittent, like a kite trembling in the sky. Everyone held their breath, fearing that the winding thread would be interrupted.

"I don't know...this sir...am I right?"

The woman's face was pale but her eyes were clear.

"What's your name?"

"Tina."

"Very good, classmate Tina, you are free."

......

Walking out of the slave market, Ham knew that the company had one more member. Even in Kerr Town, where online education has been popularized for a long time, few people could answer those three questions.

Because of Tina and the twin sisters, Mary and Jessica took the three back to settle down first, while Xiao Yang and others continued to stroll.

Compared to the crowded end of the commercial street, the stalls in the central area became less, and some items with extraordinary characteristics and other valuable technological items gradually appeared.

The whole market is a bit like an antique street.

Most of these items are junk that you can't understand. Even the stall owners don't know what they are used for, so they take them out for trading.

For example, broken weapons or magic weapons, books or scrolls that you can't understand, bones with strange patterns, and plants that are not sure whether they are poisonous or unknown ashes.
