Wu Di walked on the stone bridge, if it weren't for the occasional flickering fluorescence of the dust of illusion, he could faintly see the shadow of the stone bridge, and at a glance, he was like walking in the void.

Ling Feng stood on the edge of the stone bridge, leaning down to touch the void in front of him, the cold touch indicated that there was indeed a stone bridge in the void, but no matter how he opened his eyes, he couldn't see the appearance of the stone bridge. No matter how much apprehension and uneasiness he felt in his heart, he still stepped on the bridge and walked forward following Wu Di's footsteps.

There was a panic-black ink in front of him, and there was also a dark and bottomless ink under his feet, although his feet came into contact with the cold stone bridge, Ling Feng still felt involuntarily flustered in his heart. When he looked back, Jiao Daren also followed behind him with an iron face, obviously worried in his heart.

At this time, I looked at the stone sculptures standing on both sides of the invisible stone bridge, and found that it was so magnificent. The height of the two stone sculptures was at least thirty meters away, and even the statue of the three-headed dog of hell lying at the foot of the stone sculpture was about five meters away, like a demon from the ancient hell, coldly looking at the three Ling Feng who were trembling through the stone bridge.

The three of them stepped on the stone path in front of the castle, and only then did they let go of their fears a little.

The gate of the castle is more than twenty-five meters high, only a little shorter than the stone carving, and about twenty meters wide, and the forty-meter-high wall extends from the left and right to the depths of darkness.

Standing in front of the ancient castle, Ling Feng and the others couldn't help but feel their own insignificance and humility.

I don't know when this majestic castle like a miracle was built and what kind of creatures could have built it? At this time, I thought back and realized that this should be a huge crater. This magnificent castle is built right in the heart of the caldera.

Huge crater.

A majestic and mysterious castle.

A crack opened in the gate of the castle, and the bones of four people dressed in Taiping military uniforms fell to the edge of the gate. I think that more than 100 years ago, Shi Dakai's subordinates also walked into this castle.

Inside the gate is a wide stone path, lined with some strange and magnificent buildings. It's not very real in the dark.

Wu Di turned on the flashlight, and the snow-white pillar of light shot straight into the darkness in front of him, and the three of them realized that the castle was actually a dense and huge complex of buildings, which was completely a city that could accommodate at least 100,000 people living together.

"It seems like a temple ahead?"

Under the spotlight of Wu Di's flashlight, Ling Feng vaguely saw that at the end of the stone road was a quaint temple, according to the style of ordinary ancient buildings, the temple was definitely the core of the complex.

However, for the sake of caution, Wu Di still suggested that the three of them explore around the gate first. After getting acquainted with the surroundings a bit, head deeper into the heart of the castle.

This was a serious suggestion, and Ling Feng and Jiao Daren had nothing to do, so the three of them scattered and explored the buildings in front of them according to the agreed division.

Ling Feng cautiously walked into the nearest building.

It is a large building that resembles a barracks. Ling Feng walked into it, only to find that the layout of the buildings inside was a little strange, facing a vast open space, the size of at least ten football fields. The ground is full of uneven volcanic rock formations, and dozens of buildings resembling beast dens are scattered throughout the volcanic rocks.

As you can imagine, thousands of years ago, there was lava flowing here, and some creatures were running around and living comfortably among the lava. They may even be trained in various military disciplines, just like human soldiers.

Obviously, the soldiers who live in this barracks should definitely not be human. Otherwise, how could a military camp be built like this?

It was just strange to him that traces of human existence were found in the buildings around the barracks. Broken pots and pans, ruined stoves, quaint furniture, and even a few pieces of completely decayed human clothing in one room.

See this happens. He couldn't help but hesitate.

Could it be that the previous speculation was wrong?

Due to some special factors, this barracks should be what he saw before.

But he still couldn't figure out what kind of soldiers the barracks were trained if they were like this.

He searched several buildings in succession, and found the same condition. In the building that is completely unsuitable for the style of human life, there are all kinds of traces of human existence, although it has lasted for a long time, but there is absolutely no doubt.

As a result, he was even more puzzled.

Could it be that this is a castle where humans and some inexplicable creature live together?

After searching the agreed buildings, Ling Feng was already at a street corner. Coming to the street, as soon as the cold wind blew, he suddenly thought of another possibility!

There was a person standing at the corner of the street, and he couldn't see his appearance clearly, and he didn't know whether it was Wu Di or Jiao Daren.

Ling Feng stepped forward and was about to say hello, but suddenly felt that something was wrong. He didn't have time to think about it, and immediately flashed and hid behind a building on the side of the street.

Almost at the same time, the figure standing at the corner of the street heard the movement, quickly turned around, flashed red light, and shot three shots behind him.

This man's marksmanship was extremely accurate, and the bullets hit the stone wall where Ling Feng was hiding, sending rubble flying.

Then, without looking back, the figure flashed into the building next to him, quickly disappearing into the darkness.

Hearing the gunshots, Wu Di and Jiao Daren hurriedly flashed out of the building next to the street and quickly came to Ling Feng's side.

Jiao Daren asked, "What's the situation, Tiger?" ”

Ling Feng replied, "There are other people here. ”

Jiao Daren was shocked: "How is it possible? ”

Wu Di said indifferently: "We can find here, and others are not impossible." ”

Jiao Daren wanted to refute, but thinking about the sudden gunshot, he could only swallow all the words back into his stomach.

The three of them found a building to hide in, and since there were other people in the castle, and the situation was still not good, they could only be more careful.

Ling Feng first asked, "What's the situation over there?" ”

The three of them whispered in the room to exchange their respective searches, and they all found the same strange situation, in a house that was not at all human-style architecture, and found traces of human existence.

Ling Feng asked, "Ah Ye, can you tell the age of this castle?" ”

Hearing Ling Feng's question, Jiao Daren's eyes lit up and he understood what he meant.

Wu Di said: "I estimate that this castle should be a prehistoric relic before the Shang and Zhou dynasties. ”

Ling Feng asked again: "Then the traces of human life that you have found, such as porcelain bowls, such as clothes, what are the things of what era?" ”

Wu Di said: "It should be something before the two songs." ”

Jiao Daren said: "Tiger, do you mean that the ancient castle is likely to be a prehistoric relic, but it was later discovered by some humans and occupied it?" ”

Ling Feng nodded and said, "I'm afraid I can only think of such an explanation. (To be continued......)
