Zhao Zihan silently threw a cloth bag to Wei Mingcheng, who was at the forefront, and he turned sideways to let go of Ziyue and walked at the end of the fortification.

On the way to the broken wall, there are old marks of broken trees, grass on the ground, and signs of lodging in the direction of the broken wall.

It's just that this road is very wide, what kind of behemoth passed by here and broke the trees on the side of the road?

The grass on the ground is falling in the same direction, or is it a sign of something dragging for a long time?

There are bones everywhere on the roadside! These traces are caused by some man-eating monster dragging people into the ruins from this road!

Thinking of this, Zhao Zihan was so frightened that his heart jumped, and he couldn't help but feel creepy!

Just as he was alone in horror, Wei Mingcheng's cry came from the front, breaking the silence: "What a big hole!"

Zhao Zihan hurriedly walked a few steps, and at the bottom of the towering cliff, a huge hole three zhang high and more than two zhang wide came into view.

The dark mouth of the cave is like a huge mouth, as if waiting for people who can't help themselves to throw themselves into the net.

The four of them stood at the entrance of the cave a little overwhelmed, and the timidity and fear slowly dissipated at this time, replaced by inexplicable shock.

"This is not a miracle of nature, this is a man-made hole!"

Yao Yao's heart was as careful as a hair, touched the brown gray soil along the edge of the hole, and continued: "This is the remnants of cement. ”

"Well, yes, it's the weathered remnants of cement. ”

Zhao Zihan used to walk on the weathered cement almost every day, and he could see it at a glance.

"Reddish-brown soil, it's rust, remember Lan ......"

Zhao Zihan suddenly found that he had revealed his mouth, and he was suddenly shocked, and hurriedly stopped, and his heart jumped "thump" again.

He didn't know where the other three noticed whether he was going to say "blue" or "purple" later.

Ziyue clapped her hands and said, "It's said that it's an ancient ruin, it's naturally a man-made monument, isn't it strange to have cement and rust?"

Everyone was stunned.

I don't know who said, "Let's go, let's go in!" The four of them mustered up their courage and walked in. After only a few dozen meters of entry, the voice of speech buzzed, and the darkness that came over made Zhao Zihan and Wei Mingcheng light up the pine branches one after another.

The ground was very soft, and Zhao Zihan took a look, it should be because the cement was weathered. Under the rock walls on both sides, a thick layer of soil has been piled up, which is caused by the weathered part of the cave wall falling.

Zhao Zihan has seen this kind of scene a lot in the underground of Lancheng, so he naturally knows the reason at a glance.

He judged that this place was at least the same as Lancheng, and it was also a relic left by ancient humans three thousand years ago.

After passing through several forks in the road, all of which were blocked by the collapse and could not turn in, the four of them kept walking towards the wide place.

"What a deep hole!" Ziyue sighed.

"We've been in at least three kilometers, right? Yao Yao said.

Time passed silently, the first torch in Zhao Zihan's hand was almost burned out, and Wei Mingcheng had already begun to light the second pine branch.

At this time, they came to a fork in the road, and there were five holes side by side in front of them. Wei Mingcheng lit the pine branch and asked, "Which cave to enter?"

Before they knew it, all four seemed to have forgotten about their fears.

Zhao Zihan stepped forward to take a look, and found that there were fresh footprints on the underground mud at the entrance of a cave, and two of the other four holes seemed to be untouched for eternity, and the softening layer on the ground at the other two holes had obvious traces of dragging and pressing.

The experience of wandering in the basement of Lancheng told him that most of the two ancient holes without a trace were blocked.

So he pointed with his finger and said: "These two holes, I'm afraid that they will be blocked by a landslide, but I am afraid that they will not be able to go through not far away." ”

"At the entrance of this cave, there are messy fresh footprints, which should be the traces of the disciples of the Yushan Sect passing through not long ago. But since none of them came out, there might be unforeseen dangers inside!"

"The remaining two holes, there is something that has been in and out not long ago, and the traces are not particularly old. ”

Ziyue was startled and asked, "What is it?"

This sentence woke up the people in the dream, Zhao Zihan, Wei Mingcheng, Yao Yao suddenly opened his mouth wide!

There are no human footprints, not the footprints of beasts, just trailing traces.

What could that be?

"I thought, maybe... Possible... Well... It's a big, big bat, isn't it?"

Yao Yao covered her mouth and said with some horror and some uncertainty.

Zhao Zihan didn't answer her, but said: "If I'm not mistaken, it may be safer for us to walk through these two holes with trailing marks." ”

Wei Mingcheng waited for Zhao Zihan to finish speaking, was silent, took the lead into a hole with traces of dragging, and walked forward, and the three people behind hurriedly followed.

After walking for a while, suddenly there was a "boom" in the hole, and then the sound of spreading wings, and the four of them were suddenly startled.

The screams of the two girls were heard far away, echoing deep in the cavern.

Zhao Lihan also had a chill on his scalp, hurriedly lowered his head, glanced at it, and looked at it clearly: "Yes... It's a bat, it's really a bat!"

Ziyue listened, covered her chest with her hands, and shouted: "Oh mom, I'm scared to death! You read that right? Is it really a bat?"

"Let's go, it's a bat, otherwise what else could it be?" Zhao Zihan said.

The light in front suddenly brightened, and Wei Mingcheng shouted: "What a big hole!"

Zhao Zihan stepped forward, but the torch "sizzled", and then the fire suddenly became bigger.

What kind of gas is in it that is conducive to combustion? Zhao Zihan was stunned and looked towards the cave.

What a hole this is, this is a hollowed-out half of the mountain! The four sides are so wide that you can hardly see the end, and although there have been many collapses, you can imagine the grandeur and glory of the past.

The rows of iron bumps on the ground have rusted to the point that they can't be seen, but they can still be seen... It seems to be the book that says that the "cannon" of ancient humans?

The long rust on the ground was supposed to be a wide and sturdy track?

Yes, it's a track, and some of the small iron bumps connected into blocks can still see the general appearance, this thing is not only mentioned in "Magic Era", but also graphics, so you shouldn't be mistaken.

How many "cannons" must there be, 8,000 or 10,000? It's hard to estimate, it's so big that the torches can't see too far.

I can't help but think of what was said in an ancient book:

The "guns", "cannons" and many other weapons that we can hardly imagine made by ancient human beings have reached the level of killing gods and killing Buddhas when they see Buddhas.

Some of these cutting-edge weapons, such as powerful bombs, lasers, and neutron quantum atoms, are enough to destroy entire galaxies.

......

Zhao Zihan knew that the manufacture and use of these things required something called "electricity" and "explosives". But since the great tribulation 3,000 years ago, it hasn't been there anymore.

About this matter, remember that the ancient book describes it like this:

After the Great Tribulation, people were shocked to find that electricity, which was more important than life, was gone, and even gunpowder had failed.

"Electricity" is a thing that can illuminate and make machines spin, and has countless magical effects, carrying almost all the achievements of human civilization in that era.

Many of the surviving people at that time were called "engineers", "experts", and "scientists". These people tried everything they could to restore the "electricity", but after more than half a century of efforts, they ultimately failed.

Since then, gunpowder has only burned lightly and can no longer explode, and the guns and ammunition and various weapons of mass murder used by humans for cannibalism have all been turned into scrap metal and ornaments.

Since then, Qingming has indisputably and irretrievably become what it is now, which we call the "Cold Weapon Age".

......

Thinking of this, Zhao Zihan couldn't help but sigh in his heart: If the electricity had not disappeared, what would the human race of Qingying have developed?

Or, like the world in your dreams, you can travel through the vast stars!

Of course, there are also disadvantages, no matter how advanced science and technology are, and no matter what era or world it is, it is an eternal truth that the strong eat the weak.

On the one hand, advanced science and technology continue to create a better life, and on the other hand, it is also the most powerful "weapon" for human beings to threaten and conquer each other.

The beautiful world in the dream is still often lit by war, and the threat and clamor of war has never stopped in the mouths of some people.

It seems that many human beings always have "devils" living in their hearts.

There is a question that I have never figured out about in these countless dreams of other worlds: if such a developed technology can be developed, and if it can or is expected to reach the far outer planets in the vast universe, why do human beings still have to kill each other and compete maliciously?

Wouldn't it be good to unite and twist into a rope to explore and conquer the unknown universe beyond the planet together?

......

At this moment a wide "door" appeared in the cave wall, yes, it felt like it had once been a door, and there were small pieces of glass in the debris that fell to the ground.

Passing through this door, it seems to be a small hall of more than 200 square meters.

The walls inside are also piled up with rotten debris, and in some places you can see the traces of corroded tables, which should be some rectangular glass?

No, this thing is also available in Lancheng, which is a trace of something called "computer" used by ancient humans.

Yes, there are a lot of big pieces of "glass" over there, which are huge "computers".

One of the largest pieces, which had fallen to the ground and shattered into countless pieces, was estimated to be three meters long and more than two meters wide from the shape.

It's a huge screen? It's like a screen, right? Well, come to think of it, it's called an LCD screen.

I don't know what they call the Terrans?

Zhao Zihan didn't dare to speak out, nor did he dare to ask, which might expose himself. There was a sudden sound of "rolling" on the ground, and the ground turned slowly!

Zhao Zihan was so frightened that he was about to pull out his legs and run away, but Yao Yao, who was standing beside him, actually staggered and grabbed his clothes.

Then, the two of them fell down with a "pop", and then the ground "boomed" and collapsed!

In the darkness, Zhao Zihan felt as if he had fallen into a bottomless abyss, and Yao Yao's scream came from his ears.

For a long time, "Boom, boom!" There was a chaotic sound, and Zhao Zihan felt that he fell heavily to the ground.

Then the body seemed to roll on an infinite slope, and after a few rolls, it lost consciousness......
