Chapter 192 The Ruins
Gao Jian's judgment is very accurate. The black seam not far away is indeed an underground passage, but because the fallen leaves in late autumn are covered with mountains and forests, and it has just snowed recently, the entrance of this underground passage is completely covered. Only a small gap remains.

He walked over to sweep away the snow and fallen leaves, and the gap in front of him turned into a dark and deep hole, which was actually quite wide enough for a burly adult to pass through.

"Is this... an animal's lair?" Cao Nanqing looked towards the cave nervously and asked in a low voice.

Gao Jian took out the flashlight and swept into the cave, and found that there was actually a section of broken steps in the cave.

"No, this is not an animal's lair. Animals don't know how to build steps..." Gao Jian said, "This place seems to be built by humans."

"Humans?" Cao Nanqing was puzzled, "But according to historical records, humans did not go deep into the forest. The base outside the city was the first building outside the city built by humans besides the seven fortress cities. How could there be traces of humans here?"

Gao Jian was also very confused. It seemed that this section of steps was dilapidated and dilapidated, and seemed to have experienced hundreds of thousands of years of wind and rain. At that time, human beings were busy building bases on Blue Star. How could they have time to go to the deep mountains and old forests? To build such an underground passage?

At this time, Cao Nanqing analyzed: "It seems that this underground passage is very old. Could it be built by intelligent creatures in Blue Star? Maybe there was a highly civilized society here before humans visited Blue Star?"

Gao Jian thought about it, and this was indeed a reasonable explanation.

Judging from the degree of dilapidation of this tunnel, it is very likely that it was built longer than human fortress cities. This cannot rule out that there was an ancient civilization in Blue Star thousands of years ago, and this is exactly The remains left by the Blue Star civilization.

Of course, if you want to know more detailed information, you have to enter this tunnel.

"Go down and have a look?" Gao Jian suggested.

Cao Nanqing also had the same intention: "Let's go."

After finishing speaking, Cao Nanqing pulled out the long sword behind his back and walked towards the underground passage. Gao Jian hurriedly stepped in front of him.

"You stay behind, I'm a meat shield, and I'll explore the way."

There was a smile on the corner of Cao Nanqing's mouth, but he said verbally: "Hey, you just simulated the ability of the meat shield in the simulation system. In reality, the ability to resist attacks may not be better than mine..."

Speaking of this, she suddenly realized that Gao Jian's nitrogen replacement rate had almost broken 10%, so she asked:
"By the way, have you awakened your nitrogen element ability? It should be soon."

"Ah..." Gao Jian felt dizzy for a while, and the ability of "backtracking in time" cannot be announced for the time being.

"Not yet, maybe we have to wait, the ability of nitrogen element has never been easy to awaken."

When Cao Nanqing heard this answer, he sneered and said, "Could it be that you have awakened your supernatural ability long ago, and you deliberately hid it? Enough for chicken thieves..."

Gao Jian felt guilty for a while: "What are you talking about? Am I that kind of person?"

The two walked down the steps while chatting, and soon entered the underground passage.

The steps under their feet have indeed been weathered and corroded for a long time, and they have become very fragile. Sometimes their feet are not stable, and the two of them occasionally step on the air, but fortunately, their balance and responsiveness are excellent. Don't fall over here...

After walking down for a certain distance, the steps came to an end. The tunnel no longer spiraled downwards, but came to a spacious underground space.

This is a fairly wide underground space, the area is almost equivalent to the playground of Xiejie No. [-] Middle School. Although the surrounding walls have been corroded into disrepair, traces of artificial carving can still be vaguely seen.

This is definitely not a naturally formed landscape, it can only be the engineering of advanced intelligent life forms. Obviously, there used to be activities of advanced intelligent life forms here.

"Is this an underground city?" Cao Nanqing looked at the underground building in surprise and murmured.

Gao Jian's gaze was attracted by another tunnel.

It was a horizontal tunnel at the end of the underground space, and it was much wider than the tunnel they had passed through before. This tunnel was located on the other side of the underground space, next to the wall on that side.

When seeing this tunnel, Gao Jian only felt an inexplicable familiarity, because this underground space combined with this tunnel gave him a feeling of deja vu.

"This is……"

Gao Jian walked towards the horizontal tunnel involuntarily, and looked into the tunnel with his probe.

At this moment, he only felt a chill down his spine.

Because under the tunnel, he vaguely saw a strange thing...

Although the bottom of the tunnel was thick with dust, sand and the remains of wild animals, Takami was still able to see a stretch of mottled metal exposed...

It was a railway track, an old and decayed railway track, although its real texture could hardly be discerned, but Takami could recognize that it was a section of railway track from the outline!
No wonder the scene in front of him felt inexplicably familiar, no wonder he felt something was wrong when he saw the horizontal tunnel...

The abandoned ruins where he and Cao Nanqing were located at this time actually resembled the indispensable subway station in the city before he crossed!

"Why is there an abandoned subway station here? Why is there a subway station in Blue Star's forest?"

Gao Jian's head was about to explode, and countless possibilities poured into his head in an instant.

Cao Nanqing, who was standing beside him, saw Gao Jian's expression was different, and asked in a low voice, "Gao Jian, what did you find?"

Cao Nanqing was not familiar with the tunnels and railway tracks in front of him, because there was no subway in Yucheng, and the rail transportation in Yucheng was limited to the ground, that is, the express train connecting the seven fortress-shaped cities.

Thinking of this, Gao Jian was puzzled again.

"That's right, I've traveled to this world for so long, I've never heard that humans built subways..."

"Everything about human beings in this era is similar to that of humans on Earth thousands of years ago. There are buses, trains, and helicopters...but why is there no subway?"

"Is it because of the dangerous ores under the Blue Star?"

"Or is there another deeper reason?"

"Why don't Yucheng, Xingcheng, Longcheng, and even those foreign cities build subways?"

The more he thought about it, the more confused he became, and the puzzle became more difficult to solve.

Looking down at the railway tracks under his feet, Gao Jian asked himself again in his heart: Is the subway station in front of me, or a building similar to a subway station, the one I have seen before?Or the Blue Star people who were active here, and they also built a human-like subway station?
Seeing that there was no answer for a long time, Cao Nanqing jumped down the horizontal tunnel by himself, squatted down to push away the dirt, and observed the exposed section of the railroad track.

"This is... a track? A track similar to a train?" Cao Nanqing was also a little shocked, "The former Blue Star people built a track transportation underground on this planet?"

Gao Jian couldn't answer Cao Nanqing's question, but nodded lightly: "It looks like this, this should be an underground rail transit hub..."

Cao Nanqing tapped the rails under his feet with his saber, looked carefully at the connection units between the rails, and then commented: "It seems that the technological level of these Blue Stars is still very advanced, at least they are very proficient in the use of metals. ..."
