Ji Yuning raised the lamp to shine in one of the rooms, and Su Xiaoting also looked over.

This is a cave with a length, width and height of about 4 * 3 * 2 meters, and counting the 8 grooves cut out in the walls on both sides, each groove is about 2 * 1 * 0.8 meters.

Only a one-meter-wide walkway is left in the middle, and there is a long mound in the middle of the walkway.

In addition, there are several rows of shallow grooves dug into the wall at the back of the cave, which resemble built-in lockers.

Such a layout made Su Xiaoting think of a university dormitory.

Moving on, the caves are spaced almost identically.

In it, there is the illusion of being on the train track, as if there is a passing train next to you, and each seemingly identical carriage has staged countless joys and sorrows.

The mood of the two was inexplicably low, until about 100 meters to the end of the tunnel, they entered a living room-sized cave again, and there were three caves of about 15 square meters connected on both sides of the cave wall.

There are also 2 channel openings, which lead to the upper and lower directions.

"Let's go up and have a look!" Ji Yuning said.

"Well~"

As you go up the slope in the passage, the air becomes thinner and thinner. Fortunately, neither of them was an ordinary person, and they finally reached the end of Ruth after 6 or 7 minutes.

Ji Yuning looked overhead, the boulder that closed the passage could not see the edge, and tried to push it again, and gave up the plan to go out from here.

"It's closed, let's go back!"

When she exited the tunnel and returned to the cave with 6 entrances, Su Xiaoting guessed:

"The other 5 passages won't be the same as this one, right?"

"Actually, I thought so too, maybe the exit was on the other side where we fell."

Su Xiaoting nodded, but she still had a fluke mentality, and pulled Ji Yuning to look at the rest of the hole.

As the two of them expected, at a glance, these tunnels seemed to be carved out of a mold.

When they returned to the previous floor, the two of them chose another staircase to go up, but the result was still the same, and the exit was blocked by a boulder.

Unable to find an exit, the two had to go back the way they came, sparing a circle, and returning to the place where they fell.

Only a faint moonlight spilled into the hole through the exposed hole.

Ji Yuning walked to the mound and began to pick up the branches that the two of them had fallen from when they fell.

Seeing this, Su Xiaoting was busy helping out, and it seemed that finding food was a luxury, at least she could make a fire to keep warm and save some heat.

Two people, who seemed very delicate to outsiders, quickly set up a small pyre next to the mound.

The rest of the dead leaves are barely enough to support this long night! After all, it's cold in the mountains, let alone in this dark underground.

Seeing the rising flames, Su Xiaoting felt cold in her hands and feet, but a surge of happiness welled up in her heart.

Although it was thrilling today, and Ji Yuning was injured due to fatigue, but in the end, the danger was saved, Ji Yuning's injury seemed to be fine, and now the two of them can sit safely on the fire, which is already the love of God.

Although they haven't found an exit yet, the two have disappeared around here, and one of them will definitely come to look for them.

"Gollum~"

Su Xiaoting's face turned red, she didn't feel hungry after the meal, but this five-organ temple had to be lazy.

"I'll go over there and have a look!" After Ji Yuning finished speaking, he was going to get up.

Su Xiaoting immediately understood what Ji Yuning meant, "...... Are you looking for something to eat? But there wasn't even a single grass here. ”

Suddenly, she remembered something, and patted her head: "Oops~ I just remembered that there seem to be a few chestnuts left after picking them yesterday!" ”

Su Xiaoting groped out a handful of chestnuts from her pants pocket and handed it to Ji Yuning.

Ji Yuning thought about it and took it with a smile: "Okay, roast chestnuts for you to eat~"

With that, put the chestnuts on the edge of the fire.

"City Lord, have there been many people living here before?"

Ji Yuning took the chestnut's hand and sighed lightly: "That's right, do you know what kind of place this is?" ”

"Here...... It can't be the 'Pure City' of the Dark Period, right? ”

Ji Yuning agreed: "Exactly, according to the record of "The Legend of Boundless", in order to avoid radiation, since the 2nd year of the Dark Era, the ancestors have a tradition of establishing caves as residences, but none of them exceed the scale of Jingcheng!" ”

Su Xiaoting just vaguely felt that the scale of the tunnel was huge, and at this moment she also remembered the description in "Boundless Biography"-

'Jingcheng was built in the 53rd year of the dark period, the first occupants were 3,000, and then expanded downward year by year, with a total of 4 floors, which can accommodate 15,000 people. ’

Asked: "The time when this pure city was built was the same year as the Habin underground city was flooded?" Do you say ......"

Ji Yuning has received: "Yes, this pure city is the ...... built by the elites left behind in the Habin dungeon."

"Really? There doesn't seem to be a record on the boundless biography. When Su Xiaoting saw it at the time, she had this question.

"Maybe it's just that they don't want to face it, and in the end, they will end up with the same ending as the other remnants!"

His ancestors came from here, and although the dungeon was flooded at that time, some supplies were transported out, and the fire of wisdom was preserved for the endless land, and a huge underground city with earth and stone structures was established.

But in the end, he fell deeper from purgatory, to a situation similar to that of other remnants.

Su Xiaoting remembered the dwelling in the dungeon, compared with the anthill-like primitive dwelling just now, at least the dungeon still retains the lifestyle of the technological society.

However, Su Xiaoting thought of another possibility, "Will the exits here have all been sealed?" "Because that's what dungeons are.

"It is very likely that although this place is simple, when the ancestors returned to the earth two hundred years ago, it was tantamount to a frightened bird, and with this retreat, there are a lot less worries."

However, this also means that when they leave, they will inevitably seal this place completely, ensuring the integrity of the Pure City.

It's just that I didn't expect that time flies, and this one is more than 200 years.

In the boundless land without accurate maps, lost in the barren and dense forest, it has become a symbol remembered by future generations.

Looking at Ji Yuning, a thought suddenly popped up in Su Xiaoting's mind, if Habin hadn't been flooded by the river at that time, would Ji Yuning be like Shangguan Haozhe, who is now also a rising star of the United States with an unlimited future?

"Crackle!" The popping sound came, and Ji Yuning came back to his senses and pulled the chestnuts out of the fire.

"When I came here, I found that the current life is the best!"

"Yes~" Su Xiaoting thought deeply, if she had traveled to the Dark Age at that time, or the Endless Land, then she really wanted to die.

"Let's eat chestnuts!" Ji Yuning wrapped the chestnuts one by one, and handed each package to Su Xiaoting.

Su Xiaoting took the three, waved her hand and said, "Enough is enough, city lord, I'm not hungry at all." Eat, I'll go get some water." ”

"No, I'll go later!" Seeing that Su Xiaoting was dead or alive, Ji Yuning ate the remaining few chestnuts, which were soft and slightly sweet in the mouth, and a sense of solid satisfaction immediately rose in her stomach.

On the other side of the blue star across the ocean, in the Philippines, the strongest country in the Western Union, a 7-star resort hotel.

The hotel rises from the ground and rises 300 storeys above the sea 10 kilometres away.

On the tarmac of the presidential suite on the 288th floor, a man jumped from a civilian airship and went straight to the room.

"It's Danley? Your Excellency is bed, why didn't you make an appointment in advance? The butler greeted him.

"I have important enough business to report to His Excellency the Prime Minister personally." Said the man with sunglasses.
