The next place Tang Xian went to was the subway station.

Next to the gymnasium in the city center is the entrance of the subway station.

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

The gymnasium did not leave any notes or anything like that.

But Baichuan City is a metropolis, in the gymnasium, museums, and the city hall.

Baichuan Stadium has held many grand sports events.

Football and basketball are still retained projects today, which is enough to show that they are very popular.

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

The grass on the professional court will naturally not be artificial stadiums, but transplanted ryegrass.

This kind of grass feels good when stepped on the football field, but the length of the grass pole is between fifteen and thirty centimeters. It is necessary to arrange for people to trim it regularly.

After Tang Xian arrived at the gymnasium, he found that he had not seen the scene he had imagined.

"It turns out that the plants that grew wildly are just outside, and the plants in other cities are still peaceful inside."

Tang Xian, you said.

"What is such a big lawn for?"

"This is the place where the ancients danced. In ancient times, people liked to dance on the lawn, under the soundtracks of "The Most Charming Ethnic Style" or "Little Apple". It's so lively, you can try it another day." Tang Xian teased casually.

“I can’t dance.”

"It's very simple. The function of dancing is to exercise your body. For the audience, it is an alternative to discover beauty. You are beautiful in yourself. Your beauty is enough to make you do not need dancing skills, just make your head and pose at will."

Qing Jiuyu was a little happy and thought to himself that he was not blind either.

The gymnasium proves some of Tang Xian’s ideas.

He took Qing Jiuyu to the outside world.

Qing Jiuyu saw the basketball court again.

“Is this a dancing too?”

"Of course this is not a dancing person. Do you see the baskets on both sides? There are lines on the ground.

This is a sport that combines high jump and long jump and throwing, called slam dunk.

As the name suggests, it means that the whole person jumps high, then pours his head down into the basket.

Whoever jumps the best and looks the farthest from the basket will score the highest. You can also try it if you have the chance."

"Why do I feel like you are lying to me?"

"I read a lot of books, how could I lie to you?"

Qing Jiuyu is not stupid, thinking that humans can be so bored.

But thinking about this, she still thought about how her head was facing down and the fish leaped into the basket-

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

Frowning, Qing Jiuyu shook her head.

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

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

Tang Xian knew to look at the signs, but she didn't know. The catastrophe-level powerful man suddenly had the idea of ​​following Tang Xian, 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 with a dish-shaped metal at the top.

After Tang Xian took a look, he became more convinced that there were clues in the subway station.

He walked around the subway station inside and out, and he really discovered something.

Under the subway, there are passages.

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

But at the bottom, there are also orange sign arrows pointing toward the ground.

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, purple lights flash.

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

"It seems that it's here."

"Are you looking for that underground fortress?"

"Yes."

When traveling during the day, Tang Xian did not bring lighting devices like flashlights.

Although his eyes had already adapted to the darkness, everything in front of him was still too dark.

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

Illuminate this place in an instant.

Tang Xian glanced at Qing Jiuyu with praise, and the leader of the fox clan finally made some use.

But the fire on her fingertips is a deadly skill for her future men.

When she remembered that Qing Jiuyu could still speak out, she felt that her man was very dangerous in the future.

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

At the same time, looking at the surrounding environment, I kept testing and writing about what might have happened back then.

It’s just that time is too long and many traces can no longer be used as material for testing and writing.

Finally, a huge door blocked Tang Xian.

Every few seconds, a purple light will light up somewhere on the door.

The light is not strong, it just allows people above the passage to see it.

By the firelight at Qing Jiuyu's fingertips.

Tang Xian saw the full picture of this door.

Judging from the material, although the alloy used in this door is not as good as the equipment of the talented people in the mining area, the size of the door is enough to show its sturdyness.

The surrounding password locks indicate the way to enter. Through the pattern of the door, Tang Xian saw the pressure monitor.

Looking around, he frowned.

"It seems unlikely to force a breakthrough through this door. It will trigger alarms and defense mechanisms."

Qing Jiuyu said:

"If you want to go in, I can break this door. It's quite easy."

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

"I have seen the structure of the underground fortress. Although this door will not affect the entire area, it is underground. If you have too much strength, it may cause a collapse."

Qing Jiuyu smiled and said:

"What do you say, the master, and what do I do as a guest? Yes, master?"

Tang Xian smiled bitterly:

"What did you experience when you were a child? They were all nine-tailed foxes. Why did Xiaojiu be so simple, but you became a driver?"

"driver?"

"I'm ready to leave. There must be other clues in this city, and this door will definitely be able to open normally. It's time for us to go back."

“Are you going back now?

"Well, ask if the other groups have gained anything."

...

...

East City District.

Shortly after Tang Xian and Qing Jiuyu returned to the residence, Dong Ran, Akasi and others also returned.

Tang Suoye, Tang Feiji and Tang Xiaojiu's mentally retarded children's team had already sat in a row, waiting for the chef to return.

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

Then it tells the discoveries in cafes, libraries, gymnasiums, and subways.

Everyone was shocked.

"In other words, after the catastrophe came, our ancestors actually had corresponding ways of dealing with it.
