After eliminating the giant centipede, the team was able to emerge from the sewage pipe without encountering any threatening mutated creatures.

At the top of the sewer pipe is a large cutting machine with metal blades more than 10 meters long, where the waste that cannot be recycled is compressed into chunks, where it is shredded and thrown into the sewer pipe, where it is washed to the bottom of the landfill.

Located 260 meters above the surface and more than 60 meters deeper than Vault 444, the landfill is a naturally occurring deep underground cave that was originally a tributary of a dark river, but the groundwater in this dark river has been drained by the people in the shelter, and the hole left behind has been transformed into this landfill.

And Qi Lin and the five of them entered the landfill along the course of the dark river, and then passed through the seventy-meter-long, almost vertical sewage pipe to the current place.

This is a garbage disposal plant, but by this time the factory has ceased to operate, and the workers inside have disappeared, only a large number of compressed garbage blocks have been piled aside, and there is no time to dispose of them.

However, it was precisely because of the shutdown of the garbage treatment plant that Qi Lin and the others were able to enter Vault 444 through this secret passage, otherwise, not to mention the high-speed rotating sharp fan blades, the garbage and waste water that kept falling from the sky alone would be enough to make it difficult for them to move an inch.

"The workers here seem to have left...... "Five took off his foul-stained hazmat suit, pulled out a box from his close-fitting package, and quickly assembled an SRS sniper rifle.

"Isn't that nonsense you're talking about?" Falcon gave him a blank look, and also took out his own weapon - a pair of Gauss submachine pistols with a futuristic sci-fi atmosphere.

"However, we first need to find out if the people here left on their own or were taken away, which will also help us understand the current situation inside Vault 444." Number Three took over and said.

"Whether they left on their own or were taken away, it's not normal...... said Four, the hacker, "I've been involved in several rebellions, one of the largest of which was started by the army commander of the Vault, and in the early days of the rebellion, the rebels controlled almost the entire Vault......

"Are you referring to the Vault 188 rebellion?" Qi Lin asked casually.

"Yes, that should be the most famous rebellion in recent times, although this rebellion is full of suspicions, the organization, the shelter officials, and the consortium alliance have concealed a lot of information, and there is very little content to be disclosed to the public, but it is said that any rebel army, no matter what its purpose is, except for those who take revenge on society and kill themselves, as long as they have the ability to occupy a complete shelter, will never let the daily facilities that keep this shelter running from working."

"Yes, although the Mastermind will terminate the daily dispatch and distribution of supplies to the Vault, the rebels can still hold out for a long time with the inventory inside the Vault......" Three nodded thoughtfully.

"Three, you've memorized all the structural drawings of Vault 444 before you set off, and how many garbage disposal facilities are there in this vault?" Qi Lin suddenly set his eyes on No. 3 - No. 3, that is, No. 4 in Qi Lin's team before, he was the only architect among the five, and he had a natural sensitivity to things like architectural drawings, so Qi Lin also handed over all these jobs to him to deal with.

"That's it."

"The problem is bigger than we thought...... Vault 444, as the headquarters of the Edas Foundation, has a resident population of more than 100,000 people, and these hundreds of thousands of people will produce a huge number of excrement and waste just by eating, drinking, and lazing every day, and even if it can be recycled, this proportion will definitely not reach 100%......"

"To be precise, the current average recycling rate for each shelter is around 61 percent, and Shelter 444 is a bit higher than average, between 68.5 and 69 percent." Number Four interjected.

"Even if it's 70% good, then the remaining 30% of the garbage without any recycling value is conservatively estimated to be more than a dozen tons, and if these garbage can't be disposed of in time, the living environment in the shelter will deteriorate rapidly over time......," Qi Lin said with a serious expression.

"This kind of stupidity can only be done by the uneducated and illiterate peasant revolt leader of ancient times, and according to the information we have received, the leader of the rebels is a high-ranking figure of the Edas Consortium, his goal is to seize power, and he wants a complete Vault 444, not a large cemetery labeled 444."

"But this kind of thing...... Organizations should know about it, so why don't they just tell us? The falcon crouched on the ground, his brow furrowed, his thumb rubbing against the grip of Gauss's pistol.

After all, this secret passage was told to them by the organization, and in this case, the organization must have also known about the fact that the only garbage disposal plant in Vault 444 had stopped working, and the information that the five of them could analyze, the people within the organization would definitely be able to analyze it, and even analyze it more carefully and comprehensively, just the amount of garbage accumulated every day could be accurate to kilograms, and there would not be much error.

This situation is very abnormal, very abnormal.

"Maybe it's useless to tell us, right? After all, our mission is only to rescue the hostages, and it has nothing to do with what the rebels want. Five shrugged.

"I'm afraid it's not that simple...... Four, can you try to hack into the brains of Vault 444? Maybe we'll find something else. ”

"The Mastermind must have severed all connections to Vault 444, and the Brain that controls Vault is now in a locked state, making it difficult to hack into a locked system...... I can give it a try, but first we have to find a brain terminal. ”

"Is that kind of resource point trading terminal okay?"

"It's okay, as long as it's a device that is wired to the Vault Brain."

"That should be easy to find...... Maybe there's one nearby. Qi Lin nodded.

Just as they were about to leave, a stumbling figure suddenly appeared in their field of vision, this figure slammed through the guardrail on the perimeter of the garbage disposal plant and walked straight towards the five people.

The guardrail is welded with hollow steel pipes, although the strength can only be regarded as average, but it also requires considerable strength to break it directly.

What's more, in this person's hand, he was still dragging a long-handled fire axe, and the blade of the axe still had blood stains that had not completely dried up.

The visitor was not good, and the number five had already picked up the SRS sniper rifle with the silencer and aimed it at the opponent's head.

"Don't kill him, shoot him in the shin, we need a live mouth." Qi Lin said to his number five.

"No problem, I've always been pointing where to hit-"

"Phew!"
