Hearing that the side quest was triggered, everyone was vaguely looking forward to the rich rewards it might bring.

Tasks 1 and 2 seem to need to be taken slowly, and task 3 seems to be relatively simple to find a real place to live, and there are buildings everywhere on the roadside, which can be used as a place to live, but is there any hidden meaning of this "real residence"?

"Do you have to find a house to live in?" Someone said.

But that should be easy, right? You can discuss with the people here and pay a certain amount of money in exchange for a night's accommodation, which is not a good solution.

After the rest of the group, they got up and continued on their way.

They walked in the direction of the clue map in their hand, carefully observing the ground and walls, looking for any possible clues.

Gradually, the road became narrower and narrower, and the surrounding buildings became low, and the houses were dilapidated, with doors and windows missing, in stark contrast to the buildings just at the city gate. There are faint red rust stains on the ground wall, and the further you go inside, the more serious it becomes.

"It's not going to be abandoned, is it?" Lan Lan guessed as she looked at the potholed road in front of her and the houses that didn't seem to be popular.

As he spoke, he didn't notice that he stepped on a "floor tile" that had been loosened by perennial rust under his left foot.

In the next second, her feet were empty, and the whole person staggered, lost her balance and was about to fall to the ground.

Tang Qinqin and Mengru hurriedly stepped forward to help her up.

"Why was you so careless?"

As soon as the words of concern came out, the feet were empty, and the three of them fell weightlessly together.

The other players only had time to see a hole suddenly collapse in the ground, and when they came to their senses, they hurried over to try to rescue them.

Tang Qinqin and the three of them fell from the collapsed ground, and the light in front of them suddenly dimmed. When you get away from the ground, the temperature slowly drops, bringing coolness to your surroundings.

When I woke up from my trance, I didn't know where I fell, the surroundings were dark, and I couldn't see the light of the cave overhead.

"Where are we now? It's so dark, it's far from the ground. Lan Lan lowered her voice and said.

It's dark everywhere, and people feel scared for no reason.

"We can't go up the same way, so let's go ahead and have a look." Tang Qinqin wore a headlamp to check the place where they had just fallen, and it had been blocked by the scattered "floor tiles", and it was difficult for the three of them to ensure that they would not collapse again when they were cleaned up, and this road would not work.

The three of them put on their headlamps, leaned against each other and walked forward cautiously.

"How can there be a pipeline underground? Is this part of the labyrinth? Lan Lan guessed.

"Can't you say it's a fortification like an air-raid shelter? Or what kind of pipe? It's just too wide......"

It is like a long corridor, with two walls stretching into the distance, seemingly endless.

Tang Qinqin took a step behind and looked around at the environment in front of him. It is also the same garbage compression body as on the ground, but these have visible wear and tear, dilapidation, and even slag when touched.

Tang Qinqin found a line on a "floor tile" above his head that looked like a clue.

After careful confirmation, they found that it was really a clue that they didn't have.

"Lan Lan, Mengru, come and see."

"What, this is a clue?" The two looked surprised.

"Could it be that everything we can't find on the ground is hidden underground?"

"Maybe it's a coincidence." Tang Qinqin is still unsure.

"We count the one in our hand, and there are still seven clues missing." Mengru said, "Let's try to contact them again, and if there is really no harvest on the ground, we might as well come and take a look underground." ”

Try again and there is still no signal, and the message fails to be sent.

"We only have one clue in our hands, do we want to rely on it to clear the whole level?" Lan Lan was a little deflated, and her mood became depressed.

"It's hard to return, at least the three of us are together, it's good, isn't it?"

Tang Qinqin comforted.

"We might be able to find more clues, maybe we'll be back on the ground in a while, be happy."

"If they can't find us, we will probably come down, we are now the vanguard team, and we are taking the lead, what is there to be afraid of."

……

When Song Yuanze and the others heard the movement and turned around and ran over, it was too late, and when they rushed over to take a look, the collapsed ground was sunken into a big pit, and the fragments were messy and blocked the hole.

Everyone spontaneously stepped forward to remove the scattered floor tiles and cleared a passage for a long time.

From the ground, the passage was pitch black, and the location of the three people could not be seen.

"Let's go down and have a look." Song Yuanze said, and was the first to drill into the hole.

Lao Tian followed closely in the footsteps of his own boss.

As soon as you enter the ground, the refreshing coolness soothes the skin that is hot from the sun's rays, and makes you feel more refreshed at once.

"Boss, they're not around, they should have gone over there." Changfeng, who had already checked the surroundings, walked over and said.

After Song Yuanze confirmed that his brothers were safe, he strode towards the long "corridor".

……

At this time, Tang Qinqin and the three of them were trying to cut off a wall brick, because the exposed side of the garbage compression body revealed a damaged and yellowed piece of paper, on which were words that they were all familiar with.

“…… The first astronomical year of the Yellow Ephemeris is 2235...... The world's climate has changed dramatically, floods are repeated and frequent, and locust plagues and fires are spreading...... Grain production in various countries has been seriously reduced......" Mengru carefully recognized the blurred font on the paper, frowning and reading paragraph by paragraph.

This was the part they could see at the moment, and the other part was on the side that was tucked into the wall.

This is also the reason why the three of them did not rush to find the exit but demolished the wall here.

They vaguely felt that the words recorded on this hard-won piece of paper were likely related to side quests.

Finally, the loosened wall tiles were taken down by the three of them.

Mengru hurriedly took it and flipped it over, looking at the rest of the paper.

"Piles of garbage, occupation of arable land, depletion of resources, pollution of fresh water...... The world's food and fresh water reserves are about to run out, and the Yellow Star Humanity is in the midst of an unexpected global catastrophe...... In the sixth year of astronomy, the once-glorious Yellow Star civilization disappeared, and the surviving humans had to begin to adapt to the new living environment......"

After listening, the three of them looked at each other with solemn faces.

"So, this is the Yellow Star, and it was once a place full of human civilization? Is what is recorded on this piece of paper the secret that this city has become what it is now? ”

"There is no greenery because there is no land, there is no fresh water...... No wonder you can only eat nutrient solution, but what is the nutrient solution made of? ”

"I don't know. Anyway, the efficacy and the name don't seem to match, all of them have yellow faces and thin bodies, and they are short in stature, so they don't have a chance to develop well when they grow up. ”

"So, what do they usually do?"

"Is the original city in ruins, or is it?" More problems emerge with the information on this piece of paper.

Tang Qinqin copied a copy of the text on this piece of paper, and there was no way to take down the broken original, and walking with a piece of garbage looked a little silly.

"Then let's move on, and maybe find more useful clues."

I didn't hear the sound of the side quest completion, and it seems that there are still many details about the story behind the Labyrinth City that have not been found.
