Tang Xian's next place was the subway station.

The entrance to the metro station is next to the gymnasium in the city center.

After seeing the gymnasium, Tang Xian temporarily changed his plan and chose to go to the gymnasium first.

The gymnasium didn't leave any notes or anything like that.

However, as a metropolis, the buildings in the stadium, the museum, and the city hall are all one of the cards of a city.

Baichuan Stadium has hosted many grand sports events.

Football and basketball, as the projects that are still preserved in the pyramid today, are enough to show their popularity.

So hundreds of years ago, it should have been even more popular.

Naturally, the grass in a professional course will not be an artificial lawn, but a transplanted ryegrass.

This kind of grass has a good texture to step on on a football field, but the length of the grass pole is fifteen to thirty centimeters. It is necessary to arrange for people to prune regularly.

After Tang Xian came to the gymnasium, he found that he didn't see the scene he imagined.

"It turns out that the plants that grow crazy are only in the periphery, and the plants in other cities are still divided in peace."

Tang Xian, you said.

"What is such a big lawn for?"

"This is where the ancients danced, and in ancient times, people liked to dance on the lawn, to the soundtrack of "The Most Dazzling Folk Style" or "Little Apple", in a stadium of 100,000 people. It's lively, you can try it another day. Tang Xian teased casually.

"I can't dance."

"Quite simply, the role of dancing is to exercise the body, and for the audience, it is to discover beauty in an alternative way. And you are beautiful in your own right, and you are beautiful enough that you don't need to dance, just scratch your head and pose at will. ”

Qing Jiuyu was a little happier, and said in his heart that he was not blind.

The gymnasium should prove some of Tang Xian's ideas.

He took Qing Jiuyu and left on the periphery.

Qing Jiuyu saw the basketball court again.

"Is this also dancing?"

"Of course it's not dancing, do you see the baskets on both sides? And the lines on the ground.

It is a sport that combines high and long jumps with throwing and is called slam dunk.

As the name suggests, the whole person jumps high, and then heads down into the basket.

Whoever jumps the best and gets the furthest from the basket will score the most points, and you can try it if you have the chance. ”

"How do I feel like you're lying to me?"

"I read a lot, how could I lie to you."

Qing Jiuyu is not stupid after all, thinking that where can human beings be so boring.

But thinking so, she still made up for the way she looked like she was head-down and jumped into the basket—

It's ugly, I don't want to do this kind of exercise.

Frowning, Qing Jiuyu shook his head.

Leaving the stadium, Tang Xian walked directly to the subway station this time.

There are many entrances and exits of the subway station in the city center, and Qing Jiuyu feels that it is difficult to remember these roads.

Tang Xian knew to look at the signs, but she didn't know. This catastrophe-level powerhouse suddenly had the idea of following Tang Xian closely, afraid that he would be lost.

Above the subway station, in the center of the city's road, there is a huge tower-like building topped with saucer-shaped metal.

After Tang Xian glanced at it, he was even more convinced that there were clues in the subway station.

He went around a big circle, walked around the subway station inside and out, and really found something.

Under the subway, there is also the passage.

Generally, on the second floor is the bottom of the subway.

But at the bottom, there are also orange marked arrows pointing underground.

Tang Xian finally found the entrance.

What shocked him the most was that the entrance was pitch black at first glance.

But every few seconds, a purple light flickered.

In this city, in addition to the props brought by Dong Dye and Qiao Shanshan, he finally saw something that could emit light.

"Looks like this is it."

"Are you looking for that underground fortress?"

"Yes."

During the day, Tang Xian did not bring lighting devices such as flashlights.

Although his eyes have long been accustomed to the darkness. But everything in front of me was still too dark.

Qing Jiuyu snapped her fingers, and a purple flame ignited from her fingertips.

Instantly illuminate the place.

Tang Xian glanced at Qing Jiuyu approvingly, the leader of the fox clan finally played a little use.

But the fire in her fingertips is really a deadly skill for her future man.

Thinking that Qing Jiuyu could still spit fox fire, he felt that his man would be very dangerous in the future.

With the bright light, Tang Xian's pace quickened a lot, and he kept walking down the passage.

At the same time, I looked at my surroundings and kept writing down what might have happened back then.

It's just that it's been too long ago, and many traces can't be used as materials for testing.

Eventually, a huge door blocked Tang Xian.

Every few seconds, a certain area on the door will light up with a purple glow.

The light wasn't strong, just enough for people above the passage to see.

With the firelight of Qing Jiuyu's fingertips.

Tang Xian saw the whole picture of this door.

In terms of material, although the alloy used in this door is not as good as the equipment of the talents in the mining area, the size of the door is enough to show that it is strong.

The combination locks around the perimeter indicate the way to enter. Through the lines of the door, Tang Xian saw the pressure monitor.

Looking around, he frowned.

"It seems unlikely that a forced breakthrough through this door will be possible. Alerts and defense mechanisms are triggered. ”

Qing Jiuyu says:

"If you want to get in, I can break down this door. It's easy. ”

"Don't do it." Tang Xian stopped.

"I've seen the structure of the underground fortress, this gate is broken, although it won't affect the whole thing, but it's underground, your strength is too great, maybe it will collapse."

Qing Jiuyu smiled and said:

"What you say as a host, I will do as a guest. Isn't it, master? ”

Tang Xian smiled bitterly:

"What did you go through as a child? It's all nine-tailed foxes, why is Xiao Jiu so simple, but you have become a driver? ”

"Driver?"

"Ready to go. There must be other clues in the city, and this door must be able to open normally. It's time for us to go back. ”

"Is this going back?

"Well, ask the other groups if they have any catches."

……

……

East Downtown.

Soon after Tang Xian and Qing Jiuyu returned to the residence, the team of Dong Dye and Akasi and others also returned.

Tang Suoye, Tang Aircraft and Tang Xiaojiu's team of mentally handicapped children had already sat in a row, waiting for the chef to return to his place.

The living room was full of people, and Tang Xian took out some books first.

Then tell about the discovery in the café, library, gymnasium, and subway.

The crowd was amazed.

In other words, after the catastrophe came, our ancestors actually had corresponding ways to deal with it.

But the door was blocking me. I thought maybe we'd have to look for another clue. Did you find anything? ”

After Tang Suoye listened, he suddenly thought of the contents of the music box.

But at this time, Li Xiaoyu took out a notebook. She didn't rush to say.

"What you see in the stadium, what you write in this notebook, and the plants on the outskirts of the city, should tell us something."

Li Xiaoyu handed the notebook to Tang Xian.

"Is this note still recognizable?"

"Well, the owner of the note has put the notebook in a bamboo box, which is well sealed, and it is under the shade of the tree, and it is blurred in some places, but the owner of the note obviously wants some of his thoughts to be known to future generations, and she has written the same content in many copies. You take it and see it. ”

Tang Xian took the notebook, opened it, and began to read the contents.

"The mutation has begun. Bad news keeps coming from one city after another. Terrifying beasts and machines are beginning to invade us.

Baichuan City has not actually been affected, but everyone has received the news, and in the northern cities, there have been people with news.

There is the ark of God. Someone was waiting for us there.

Images of the huge tower kept coming, and it stood quietly on the ground, with its entrance wide open.

People began to flee, and more and more people went to the pyramids to escape the machines and mythical beasts.

But I didn't go. I remembered a story I heard when I was a kid.

One day, a tear fell into the tank, and the fish became wise. They are amazed to find themselves in an ecological environment where there are many coincidences, and all the living conditions are so just right.

The wall of the fish tank is a protective cover, which provides the most basic survival guarantee for the fish, the outside of the protective cover is very scary, and they can't even survive for a few minutes, they don't want to go out, but they can't rush out.

There are also water circulation and filtration systems, where the water that lives always flows into an inexplicable black hole and returns with the elimination of germs and life-threatening impurities. There are also miraculous oxygen supply systems and automatic feeders with unstable temperatures......

There is a heating rod in the tank, which is made with a technology that is impossible for fish to understand and recognize, and it is always releasing energy to keep the tank at a constant temperature, so much energy that the fish cannot imagine the process of its formation.

Fish are dying and fish are coming in. But as fish, their memories are so short, no fish panic, no fish feel sad, and the comfortable environment makes them reluctant to escape from the fish tank, and even worship the owner of the fish tank as a god. ’

I looked at those huge towers, and for some reason, I thought it was a fish tank.

Sooner or later, we will be eaten by the owner of the fish tank.

The timing of the tower's appearance, the timing of the appearance of alien beasts and machines, is too coincidental.

But our fear still drives us to keep pouring into the fishbowl.

I call on everyone to stay in Baichuan City, as long as we work together, we will definitely be able to defend this city.

At first, someone responded to me.

We will be able to move things, such as vehicles parked at the entrance to the city.

A large number of vehicles were driven to the entrances of the suburbs and towns, and with the help of everyone, we were able to form a huge gate from these steel vehicles.

During the day we went out in search of food, and at night we took refuge in underground fortresses.

With enough care, we will be able to stay in this city.

I tried to build a fortress of the city that was cut off from everything. I don't want to leave Baichuan City, where I was born and raised.

But when my companions saw the crazy plants, they all changed their minds, and they screamed that the world was going to destroy humanity.

Panic began to flee.

I said loudly that this world wants to protect us, and the reason why these plants grow crazy must be driven by the will of this world!

But they called me a madman.

The refusal of the animals to come in is the best proof of this, whether it is the man-eating beasts or the tame herbivores, they stay quietly on the other side of the plant wall, and never enter the city.

It's as if it's the will of this world that drives them to be the food for the future of our humanity!

The world is keeping us!

But no one believed me, and more and more people began to flee to the huge tower.

There were a lot of images coming from the tower.

People live happily in it, and there are enough supplies stored in it.

They ate semi-liquefied food, which didn't look good at all, but everyone looked satisfied.

More and more people enter the tower, but they only see the first floor.

I'm thinking, what about the second layer? What about the third layer?

There are more and more people, and there will definitely be people entering the second floor, right? What kind of person is that?

The materials and energy in the pyramid are also limited, so how can human beings get materials at that time?

For some reason, the more I thought about it, the more terrified I felt.

I'm trying my best every day to keep the people in this city, but the people in this city are still decreasing little by little.

I know I can't blame them. A wave of panic struck, and many kingdoms and cities were destroyed.

In the face of those powerful monsters, there is nothing we can do about it.

At this time, the ark of God appeared, and how many people cared that it was a fish tank?

Maybe I'm really that crazy person?

I don't want to go.

I started hallucinating.

It was as if I heard the world crying, and in July, the river broke and the rain continued.

My health is getting worse and worse, and I wish there were still people in this world who could choose to stay.

But the city is getting quieter, and at night you can only hear the sounds of reptiles and mice.

The plants had stopped growing, and the people who had been clamoring that the plants would hang the city were no longer able to see it.

What kind of life will life be in the tower?

Will they come out again in the future? Will the world accept them?

It tried so hard to protect us, but we betrayed it.

I felt an unspeakable heartache as my family and friends all entered the huge fortress like a tower.

What was their last impression of the world?

Is it endless destruction and ruin, or is it a hell full of danger and death?

It's so gentle to keep us!

I know my time is running out.

But I'm going to stay here, I'm going to witness the truth, I'm going to die with this world.

Either I'll be tortured to death by the disease, or I'll be eaten by the beasts.

But I know that there are no beasts of prey.

After everyone enters the fortress, those beasts and machines must have disappeared, right?

Books, documents, most of the history have been left in this world.

Maybe in the next few hundred years, the fish inside will also think that only the fish tank is safe, right? ”

The notes are not over, there are some diaries behind them, but they are already a little illegible, and at the end of this notebook is the name of this pathetic man.

Signed: The last human in this world, Jing Jian.
