Looking at the electronic octopus that ran away happily, Song Ziyu asked, "What is this?" It looks so fucking abstract!"

Lin whispered, "These are the patrolmen, the outer patrol units of Xihe in the underground lair."

"They don't seem to be able to fight."

Song Ziyu pondered, "I should be able to pinch it to death easily."

Lin rolled her eyes and scolded, "Are you an idiot? Do you know why these things are called patrolmen?"

"Why?"

Song Ziyu asked.

Lynn explained, "It's called that because all the patrolmen are connected to a big data hub behind them, and if you dare to do it, you will immediately alarm all the defense units in the entire ovaries! At that time, you just wait to be beaten. You tell me how many of these things can you fight?"

Song Ziyu realized that things were not ordinary.

"So, if you pull your whole body, maybe I kill one of these things, and even Xihe knows about it?"

Song Ziyu asked.

Lin nodded and said, "Looks like your pig head isn't bad."

"Little girl, talk well, we can still be friends, who is the pig's head?"

Song Ziyu was not happy, and was ready to give Lin a big wall.

But considering that Lin was weak and couldn't eat her own slap, she had no choice but to give up.

The two continued to walk forward, and were successively investigated by several patrolmen.

However, these electronic octopuses ignored Song Ziyu directly after seeing them, which aroused Song Ziyu's curiosity.

There is no doubt that the problem is in the extremely ugly clothes on his body.

It is precisely because of the camouflage of this dress that he can hide from the investigation of the electronic octopus.

This situation is a little interesting, Song Ziyu opened his mouth and asked, "Is this dress so magical?"

"Don't ask what you shouldn't!"

Lin didn't seem to want to explain anything, just walked straight forward with Song Ziyu.

However, after taking a few steps, Lin still said, "This camouflage coat is the masterpiece of Teacher K, and it is through the effect of this garment that we can move unhindered in Xihe's ovaries."

"Got it!" Song Ziyu said, "It seems that Lao K is still a little useful."

Lin said, "K Lao is not as simple as you think! As one of the few people who have escaped from prison, Elder K can almost be regarded as the chosen one."

"Is that amazing?" Song Ziyu was a little unimpressed.

"You'll find out later!"

Lin didn't bother to explain anything, just walked forward with Song Ziyu.

Soon, the lengthy corridor was completed, and then the scene presented in front of Song Ziyu's eyes made Song Ziyu stupid on the spot.

Standing on the platform, Song Ziyu saw a scene that can probably only be depicted in Dante's literature!

Beneath was an endless abyss, and overhead was a blood-red firmament.

What connects the blood-colored sky with the endless abyss is an innumerable petri dish!

These huge petri dishes, like bee chrysalis in a hive, are densely arranged.

In every enclosed cultivation chamber, there is a living human being!

These humans are bloated and their eyes are closed, and they can't tell whether they are alive or dead...... Looking around, Song Ziyu roughly estimated that what he could see in front of him, at a glance, there were at least hundreds of thousands of people!

Each of these chambers is connected to a separate tube that looks like a fat intestine, one end of which is inserted into the person's mouth, and the other end is connected to the blood-colored sky overhead.

Obviously, the bodies of these guys are dependent on the "food" in the tube to sustain their lives.

"What the hell is Xihe trying to do by keeping these guys in captivity?" Song Ziyu was shocked, and after watching the old man for a long time, he couldn't help but ask.

Instead of answering directly, Lynn asked a question.

"In today's resource-scarce world

What is the most valuable thing in the world?" Lin looked at Song Ziyu and asked. ap.

"I don't know."

Song Ziyu finally stopped being a bartender.

Lynn replied, "As you can see, in times of scarcity of resources, people are the most valuable things."

"So how do you embody the value?"

Song Ziyu still doesn't understand a little.

"There are more valuable places for human beings."

Lin took Song Ziyu along the path carved out of the cliff and walked step by step to the bottom of the abyss.

"Listen carefully!"

Lynn suddenly reminded.

Song Ziyu looked up suddenly, and found that the blood-colored dome above his head came from the sound of "gurgling".

Immediately, the tubes connected to the culture chamber visibly poured out a large amount of cloudy food.

The food is poured directly into the mouths of the humans in the culture chamber through tubes and high pressure...... No, this tube should be inserted directly into the stomach, these foods are really fucking one step to the stomach.

"What do they eat?"

Song Ziyu asked.

"A high-calorie food made by mixing cockroaches, rats and fecal residue in a recycling process...... These things can quickly provide all the calories your body needs, and even valuable protein, but I guess you won't be able to eat it."

Lin said lightly.

Song Ziyu stared at the people eating.

These people are eating completely unconsciously, and the tube will not care if you can't eat, just pour it into your stomach until the belly of these men and women is round!

Seeing this scene, Song Ziyu remembered a delicacy in the West in the era of civilization: foie gras.

Legend has it that in order to obtain a large amount of foie gras, the breeder will fix the selected high-quality goose in a closed environment and feed it with a stuffed feed.

The so-called feeding is to add high-energy and high-protein food to the daily diet of geese, pour two or three kilograms of food every day, and use electric pump assistance if you can't eat!

This way of eating is simple and crude, and it only takes a few seconds to fill the food.

In this way, the foie gras can be inflammated, and the largest can be ten times the size of wild foie gras.

Sometimes one foie gras can reach 900 grams......

The scene in front of me is quite a bit stuffed.

So Song Ziyu couldn't help but blurt out: "Xihe doesn't want to eat human liver, right?"

"Shit!"

Lin said slowly, "What Xihe wants is the feces of these people."

"Feces?"

Song Ziyu was stupid.

"What is Xihe doing with the dung?"

Song Ziyu said, "I didn't find that it has such a special hobby."

Lin sighed and explained earnestly, "The world has been so overexploited that it is almost impossible to find any useful resources, so people have become resources. What can I do with, you ask? Manure has many functions and can be recycled into food...... Of course, the most important thing for Xihe is to generate energy."

"Generating energy?"

Song Ziyu's eyes widened.

Immediately, Lin gave Song Ziyu a science popularization of chemistry.

The manure is treated with water and then goes into a reserve tank.

The warm, oxygen-free reservoir contains a large number of microorganisms that decompose edible feces.

These microorganisms will break down the complex carbon-based molecules that make up the feces into simple molecules.

Finally, the decomposed manure will be expelled in the form of gas!

This exhaust gas contains a large number of carbon-based molecules.

Methane accounts for a large proportion.

The methane gas produced is collected and then processed by a generator set to form a biogas power generation system.

In this way, after a series of processes, the power generation system can be utilized

Get a steady stream of power!

What is electricity?

It's energy!

It's the energy that Xihe depends on for survival.
