The crowd had already left the city far away, and there was only a deep passage that spread out all the way in front of them. Looking back in the direction of the city, there is only a faint glimmer of light - which requires a vision beyond the limits of human eyesight to see.

Surrounded by a foul and almost toxic gas, it was clear that Hao Ren had chosen a gate that had never been opened: the back of this door had never been ventilated.

The passage is very wide, and most of the places are structurally intact, without the expected crampedness and dilapidation. It's just a pretty old and dirty place, with a thick layer of dust everywhere, everything bearing the signs of the erosion of time, and it's clear that it lacks the necessary clean-up compared to the fully enclosed and constantly operating city.

In the center of the passage you can see a number of steel rails arranged in parallel, which, although different from the railroad structure on Earth, is clearly intended for some kind of large transport vehicle. If nothing happens to the planet, the passage would be a busy subway line – an important artery connecting the city to a major transportation hub. But now it's just an abandoned cave that has been abandoned for 10,000 years, and the only thing that accumulates in it is the old machines that I don't know if they can start.

The ceiling of the passage is inlaid with a row of dim lights, eighty or ninety percent of which are in working order, and these lights are the only proof that the passage has not been completely abandoned. Hao Ren could see the surroundings clearly through the not-so-bright light, and Hao Ren saw all kinds of discarded machinery piled up on both sides, including rusty carriages and dusty machines. Lily stepped forward to check it out, and jumped back to report the situation: "The model is different from the one in the city, and it looks a little more primitive." ”

"In other words, those machines in the city are all evolutionary versions." Hao Ren nodded slightly, "It seems that some kind of 'research and development work' is indeed going on." Machine qì in the ...... of renewal This is something that needs to be created. ”

"These planes should have been abandoned before the planet set sail...... Maybe it was abandoned earlier, like 10,000 years ago. Izax looked at the broken brass and iron that passed by, "It looks like it was suddenly abandoned, something must have happened at the time." ”

Vivien's eyes flickered reddish in the dim darkness as she suddenly saw something she cared about in a pile of clutter, and several small bats fluttered past, churning out a small metal plaque in the clutter. Hao Ren took the metal plaque from the little bat's claw, and found that there were some pictures engraved on it, and the picture was a middle-aged man with a strict expression and meticulous clothes, and he felt that this face was somewhat familiar at a glance. After thinking about it for a while, it suddenly came to pass: this is exactly the middle-aged man I saw on the curtain wall of that hall before I entered the shelter!

It was the first strange face he had seen on this planet.

Nangong Invincible came over to take a look, and his face showed a slight surprise: "This person seems to be called the Great Commander." ”

"The Grand Commander?" Hao Ren raised the metal card in his hand, "You know him?" ”

"He'll appear on the screen, that's the TV you are talking about," Nangong Invincible nodded, "Except for big things, he only appears once a year." He was the highest official in the area, so he was very impressed by him. ”

"The supreme governor of this planet......" Hao Ren flicked the dust on the metal plate. He appeared on the big screen, but the date of his birth and death was written under the sign, and the note was written with deep mourning. Supposedly, only those who have died will be marked with XX to XX years after their names, right? ”

"This archon is dead?" Vivien looked at the plaque in surprise, "...... Then it seems that the people we see on the screen have more meaning. ”

Hao Ren nodded. Lead the group to continue walking deeper into the passage.

After an unknown amount of time, the passage came to an end, and the group came to a large open cavern that looked like a subway interchange.

The large caves are largely oval in shape. Circular tunnel entrances and exits can be seen on the walls of the cave on all sides, and each entrance and exit is exactly the same. And there are long railroad tracks that stretch out. Where these rails meet, there is a huge saucer-shaped building. It is undoubtedly an important hub in the heart of the planet's metro network. The circular tunnels around it were supposed to lead to various other cities.

The group cautiously stepped into the saucer-shaped building in the center of the cavern, the ancient facility still intact, but completely shrouded in darkness, and it was unknown if the energy system was offline or if the lamps were all broken. Lily was very happy to hold up her own fire and use it as a torch to light everyone, and in the flickering firelight, everyone saw the criss-crossing railway tracks, the dispatch platform full of debris, and the dilapidated control hut of Yan zhòng.

A few small bats fluttered into the surrounding darkness, and they didn't know what the little guys had touched, and suddenly there was a sound of mechanical friction echoing in the "subway station", and then the lights on the ceiling suddenly turned on, startling everyone.

After confirming that it was only the lighting system that was activated, Hao Ren breathed a sigh of relief and began to look around curiously. He was suddenly attracted to the sight of an intricate group of sculptures standing in front of the intersection of several railroad tracks.

The sculpture depicts a group of strangely behaved humans, huddled in a circle, hands raised to the sky, and above them floats a strangely shaped object, a radial mass of metal, which seems to represent an amorphous mass of light or lightning. Vivien looked at the sculpture and muttered, "It's kind of like documenting a third type of contact." ”

Hao Ren didn't say anything, just bent down and gently brushed away the thick dust of the sculpture base. Unsurprisingly, there are still uneven relief handwriting remaining, and more than 10,000 years have passed without completely erasing the writing on this special alloy. It was written in a short sentence: "Always remember and thank the people of the stars for their warning." ”

"People of the Starry Sky?" Lily muttered strangely, "Aliens? ”

Nangong May frowned and thought for a while: "Could it be that this kind of alien called the people of the starry sky came to warn that the humans on this planet made the ark?" ”

Hao Ren didn't say a word, just stared at the word "people of the starry sky" in a daze, he felt an inexplicable sense of immediacy surging into his heart, and after thinking for a long time, he suddenly realized that he had seen a similar phrase elsewhere: "'Allies from the stars' - do you remember that this race was mentioned on the planet Horletta?" ”

With his reminder, others remembered this incident, and Nangong May's eyes were incredible: "You said that the people of the stars mentioned here and the 'allies of the stars' of Holletta are the same group of people?" ”

"It's just a guess," Hao Ren stood up, looking at the abstract lines above the sculpture group, "Many things on the dream plane are connected, and so far, what is happening on any planet is not isolated. ”

Lily looked up at the sculpture for a long time, and suddenly had a feeling: "The people of the starry sky look like sea urchins." ”

Nangong May corrected very strictly: "Sea urchins don't look like this-you don't believe that I will change ...... for you"

"You two be quiet," Vivien glared at the dog and the fish, "let's go, maybe there are more clues ahead." ”

The group searched around the building, and finally found an underground space underneath the building. The underground space is unusually large, almost the size of the saucer-shaped building above, and in the center of the massive basement is a large structure made up of several curved structures that resemble elevator supports. Lily ran to the side of the facility and lowered her head to look down, and immediately squatted on the ground and quickly rubbed back: "It's so deep down there!" ”

In the center of the "lift support" is a cavity with a radius of more than ten meters, and a straight down tunnel stretches into the endless darkness. Remnants of alloy rails can be seen on the four walls of the tunnel, but the elevator that was supposed to be at the top of the tunnel is missing.

Of course, even if the elevator is still here, it's hard to say if it will still work - this place is not like a city shelter, and there is little sign of maintenance.

Vivien casually conjured a small bat and threw it down, waiting for a long time before shrugging: "It hasn't fallen to the bottom yet." ”

Lily raised her hands and shouted, "I don't jump anyway!" Whoever forces me I bite whom! ”

"I don't need you," Hao Ren rolled his eyes, "Vivien, let's go down - the others will wait on this." ”
