Doomsday survival game? I became a boss by picking up trash

Chapter 175

There are no traces of human intervention or machinery inside this cave; it is entirely natural.

Song Yu led the way, even though she had never been here before. However, with the database of the mechanical worm source virus, she wouldn't get lost.

Water droplets dripped from the stalactites as Song Yu and the others walked quietly through the narrow and dimly lit cave.

Only their footsteps echoed continuously in the cave; no one made a sound.

Soon, they reached the end of the cave, where a fork in the road appeared.

Three deep cave entrances suddenly appeared before them.

This cave has never been visited by humans, and there is no route to follow.

Just as one player was about to speak, Song Yu chose one of the paths without hesitation and entered.

Song Yu left, and they had no choice but to follow.

The road ahead was getting narrower and narrower, making it difficult for Xiao Hei to pass.

It's too big.

"Xiaoyu, I'm fine."

The rough stone wall had already scratched Xiao Hei's skin, leaving red marks. Although it couldn't break through Xiao Hei's defenses, it was still quite uncomfortable for it.

"Song Yu, is this really the right path?"

Ning Hechuan couldn't help but ask.

He has a bit of claustrophobia, and to be honest, he's feeling very uncomfortable right now.

He couldn't control this instinctive panic.

Moreover, they don't know how long they will have to walk this path.

Song Yu ignored Ning Hechuan. She squatted down and touched the red marks on Xiao Hei's skin, pondering for a moment.

Xiao Hei probably won't be able to get through the rest of the road unless there's enough space to fit it inside.

However, apart from her, there was no way for any other living being to enter the portable medical space.

"Let's take a rest first."

Song Yu stood up and addressed the crowd.

They are currently at least two thousand meters underground, and Song Yu estimates that they are likely three or four thousand meters underground. The machines will not be able to detect them for a while.

The road is definitely correct; Song Yu has a clear understanding of the flow and distribution of the water veins.

However, the path ahead is very narrow, and only a few children can pass through normally.

"Can't we change our route?"

Another player voiced their doubts.

"This is the right way. There is an underground river ahead. If you have a more correct route, you can leave."

Song Yu glanced at the group of people who were speaking, his tone revealing neither joy nor anger.

"..."

they do not.

Moreover, leaving the main force at this time would be tantamount to suicide.

Such a dark and oppressive environment can easily lead to negative emotions.

"Can we dig this rock wall open?"

Sister Shen tapped on the stone wall; it wasn't too hard, and a normal human would definitely not be able to dig it open.

But they are not normal human beings.

"Will it alert the machinery up there?"

Tang Hong frowned.

Digging it open isn't difficult; the problems are the machinery above and whether the cave will collapse.

"According to the map, the area above is a nature reserve, and there is no machinery there."

"Our only concern is whether we will collapse this cave."

Song Yu glanced at the map and saw that there were no mechanical towns nearby, so there was no need to worry too much.

"This kind of environment is like something out of a road horror movie."

The crybaby sat down, gazing at the deep passageway, and said in a low, mournful tone.

"There might be cannibals or something."

"The traveler was being chased by cannibals and got stuck in a narrow cave, unable to move forward or backward, and could only watch as he was slowly eaten by the cannibals."

"Or it's like an adventurer who loves adventure, discovers a cave that has never been explored before, packs up their gear, and sets off."

"They discovered that this cave was beyond their ability to conquer. When they tried to leave, they found that their dead companions had already blocked the way back."

"They could not leave; they could only remain in the cave passage, quietly awaiting death, slowly feeling their lives slip away."

"The oxygen gradually thinned, and they began to have trouble breathing; the narrow stone walls rubbed against their chests..."

Upon hearing the crybaby's words, Ning Hechuan's hair stood on end, and he felt like he couldn't breathe.

That's a horrifying way to die!!
"No, don't say such scary things."

Ning Hechuan stammered.

"What are you afraid of?"

The crybaby looked at Ning Hechuan strangely.

"We're not those adventurers. Can those adventurers dig through stone walls with their bare hands?"

"No, the rocks here are too hard, we can't dig through them."

A member of the national team shook his head, holding a tattered manuscript.

There was also a crooked, high-damage dagger next to it.

"We'll need to use explosives."

No one could answer that question. If they planted the bomb, the machines would know they were there.

That would be a real dilemma, a situation where you'd be left with no one to turn to for help.

Song Yu gently tapped the stone; this underground cave was indeed quite unique.

Looking around the cave from Lingdong's perspective, one might think that humans don't necessarily have to live on the ground.

If they had a naturally fortified place to live like this underground cave, they could easily move back to their former land.

Lingdong's understanding of this world is definitely deeper than Song Yu's. After entering this place, all signals disappeared.

Even the signals from an AI wouldn't be able to penetrate this place.

"Xiaoyu, shall I give it a try?"

Xiao Hei tugged at Song Yu's clothes and whispered.

It has a talent for digging holes.

Song Yu also remembered this matter; Xiao Hei might really be able to do it.

Sharp claws sprang out from Xiao Hei's paw pads, just like a cat's.

Xiao Hei silently upgraded its talent and evolved it again.

The experience points that Song Yu gave it before hadn't been used up yet, and now they're coming in handy!
The claw blade swung at the stone wall, easily slicing off a large chunk!
Everyone breathed a sigh of relief, especially Ning Hechuan.

That way, if something were to happen, he wouldn't actually be buried here.

Once it discovered it could be dug, Little Black's claws moved with divine speed, frantically widening the passage!

Song Yu and the others followed behind Xiao Hei, while a group of members of the human resistance army went ahead to scout the way.

Ling Dong secretly memorized all the information about this cave, planning to discuss it with the others after returning to the human resistance territory to see if they could secretly create an underground world.

Xiao Hei was very fast, with great stamina and strength. In just over three hours, he led Song Yu and the others to the end of the passage.

At the end of the passage were eighteen new cave passages for them to choose from; the place was like a maze.

Song Yu closed his eyes and quietly felt the distribution of the water flow.

A moment later, she opened her eyes and led the group through one of the passages.

This passage is different from the previous one; it is very wide.

It only takes two minutes to reach the end.

Despite the straight-line distance being only a few hundred meters, it took Song Yu and her team several hours to reach their final destination.

A huge underground lake.

The lake water was crystal clear, icy cold, and had a deep blue hue.

"I have a feeling that there's something hidden down there."

The crybaby squatted down and put his hands in the water. Apart from feeling cold, he didn't feel anything else.

An eerie blue light shone on everyone's faces, making them appear terrifying. "..."

Ning Hechuan silently distanced himself from the crybaby, who had told many scary stories to frighten people along the way.

Song Yu sensed that there was something in the water.

However, it's definitely not a big one.

She squatted down, mimicking a crybaby, and put her hands in the water to quietly feel it.

As soon as she put her hand into the water, she felt a strange sensation coming from the other arm, which was made of mechanical worm-borne virus.

The mechanical worm-derived virus is alive.

Song Yu was well aware of this.

"..."

Is there anything wrong with the lake water here?

Song Yu glanced at Xiao Hei, who silently filled a large amount of lake water and put it into its spatial storage.

What connection could there be between a mechanical worm-borne virus and something in the lake water?

Song Yu withdrew his hand, and there was nothing unusual about his arm.

Suddenly, she took out a piece of mechanical wreckage from her spatial storage and threw it into the water.

The wreckage was quite heavy and sank into the water very quickly.

Others might not have noticed, but Song Yu sensed that something in the water seemed to be gathering towards the wreckage, and that the wreckage was being digested.

A strange light flashed in Sang Ning's eyes; she saw it too.

Sister Shen, Chu Lang, Tang Hong, and several others, including Ling Dong of the Human Resistance Army, were all observant people. They all noticed this, but no one spoke up.

It seems the aircraft can't go underwater.

Song Yu and Sister Shen exchanged a glance. Since the aircraft couldn't go into the water, they would have to swim across.

Song Yu estimated that it would take more than half an hour to reach the next section of the new waterway.

She's fine, and Xiao Hei should be able to too.

It's just that other people don't know if it's possible.

"We'll have to get in the water; it'll probably take an hour to swim. Can you manage?"

Song Yu specifically asked for a little more time, in case something unexpected happened along the way.

"We have no problem."

Ling Dongchao Song Yu nodded, then gave an order to a member of the human resistance.

"Xiao Ni, go down into the water and scout ahead."

"Yes, Lord Lingdong."

The little boy with the blue buzz cut quickly dove into the water, giving no one else time to react.

"Hey--"

Ning Hechuan instinctively wanted to reach out and stop him, but the child disappeared as quickly as an eel.

"We don't know what's going on in this water. Can a child handle it?"

"We are soldiers."

The remaining children, their indifference tinged with dissatisfaction, turned to Ning Hechuan and emphasized.

They are warriors carefully trained by the human resistance, so why have they always been treated like children?

"Sorry, it was just a subconscious reaction."

Ning Hechuan touched his nose. None of the dungeon worlds he had experienced before were like this one.

Even in those worlds, children are protected; they are the future.

"No need to apologize, thank you for your concern for Xiao Ni and the others."

Lingdong shook his head, a smile appearing on his face.

He prefers to interact with normal human players like Ning Hechuan.

"I don't think I can do it, I can't swim."

One player timidly raised her hand; she couldn't swim.

"It's okay, there should be scuba diving equipment in the luggage that Alan prepared for you before."

He stopped abruptly halfway through speaking in the Lingdong dialect; he had just remembered.

That diving suit was made of a special metal.

It seems like that might not work.

Song Yu glanced at the time; they didn't have much time left.

They can't keep waiting to solve her problem.

To be honest, if she hadn't been able to solve Xiao Hei's problem, she might have chosen to leave Xiao Hei inside the cave.

At least here, Xiao Hei is safe.

"What's wrong with that wetsuit? Can't it be used?"

"Ah."

Lingdong nodded. The metal would be eaten by aquatic creatures, and the most dangerous thing would be when they were halfway through swimming.

"You're not going to leave me here alone, are you?"

The player looked at the group with some panic; she didn't want to be left here alone!
"How could that be? Nobody would do that, right?"

Another player spoke up, his smile appearing very forced.

This is another person who can't swim.

Killed?

Sister Shen, with her hands in her pockets, turned her head to look at Song Yu and asked.

Since everyone will be competitors once we get to the Feng Hua Mountains, we might as well kill them here.

It seems the AI ​​hasn't detected them, so there's no need for stepping stones anymore.

What if we leave them here and they go to the AI ​​to expose them?
Song Yu also tended to agree with Sister Shen's view; this instance was different from others, and she didn't have that much kindness.

If we can't get them away, we might as well kill them to avoid any future troubles.

“We have oxygen cylinders in our backpacks, so we should be able to make a simple diving device.”

Chu Lang suddenly spoke up.

Several players who couldn't swim immediately looked at Chu Lang gratefully. Sure enough, no matter what, the most reliable people were still these national team players!
Once they get out, they'll join the national team!

"Okay, but we don't have much time left."

Song Yu shrugged. If Chu Lang and the others were willing to take responsibility, then it didn't matter.

As they were talking, the rebel named Xiao Ni emerged from the water.

He was completely unharmed.

"Lord Lingdong, there are no problems underwater. The water is calm and visibility is clear."

Xiao Ni respectfully addressed Ling Dong.

The crybaby handed Xiao Ni a towel, who was dripping wet and looked very uncomfortable.

"Thank you."

Little Ni politely accepted it and thanked the crybaby.

Chu Lang and his group over there also made simple diving suits very quickly, and soon finished two sets of diving suits.

They avoided all metallic materials.

I tested it in the water, and it works.

The few players who couldn't swim breathed a sigh of relief. Great, they wouldn't be left here.

"Then get ready to go."

Song Yu and the others had changed into light clothes suitable for water.

To prevent herself from getting lost in the water, Song Yu tied herself and Xiao Hei together, ignoring everyone else.

When others saw what Song Yu and Xiao Hei were doing, they immediately followed suit.

"Let's go."

Song Yu and Xiao Hei jumped into the water together, each carrying a lamp they had taken from the Ocean World—the same lamp from the Wizard Mirror's lair.

Even in water, it won't go out, making it perfect as a guiding light.

The lake water is icy cold and can easily cause hypothermia.

They need to hurry!
