The terrain below is flat, the surrounding cave walls are smooth, and there are two entrances and exits.

The two of them jumped down from a damaged place on the top of the cave.

swish swish

At least seven or eight red ants over one meter high appeared from an exit, and they rushed towards them as soon as they saw them.

Xia Bai's eyes were bright, he raised the knife in his hand and killed seven or eight red ants in the blink of an eye.

A series of prompts sounded in Xia Nan's mind that he had obtained the origin of the spiritual path.

It's a pity that the spiritual source obtained by killing these mutated red ants is too little.

After passing through an entrance, a passage twelve meters wide and twelve meters high appeared. To Xia Nan's surprise, both sides of the passage were carved with mysterious and complex patterns.

After the system scanned it, it was found that these were spiritual patterns, engraved on them for strength.

The deeper you go, the more giant red ants there are, and some incomprehensible abstract reliefs appear on the walls on both sides.

Xia Bai kept killing.

But these giant red ants were not as numerous as they thought. After killing more than two hundred of them, they were gone.

After passing through the long passage, the two found a deep pit in front of them, about three hundred meters in diameter, vertically downward, and bottomless.

Xia Bai stood in front of the pit and looked around. After carefully feeling the breath in the pit, he pondered for a while and said: "Master, I felt an unusual breath in this pit. This kind of breath is in the pit."

It has appeared in my inherited memory. I don't know exactly what it is, but I think it is this kind of breath that caused the originally mutated ants to mutate again."

Xia Nan's expression changed. Xia Bai was probably talking about the aura emanating from the incomplete space-time artifact "Moon Star" prompted by the system.

It seems that the artifact is not far from here!

According to Xia Bai's judgment, the space-time artifact Moon Star is probably in the underground city.

Outside the Falling God Abyss, the system could only roughly determine the location of the space-time artifact Moon Star, but it did not point out where the space-time artifact was, which he needed to find.

And now, this goal is likely to appear.

"Let's go down!"

Xia Nan and Xia Bai jumped down.

There was a roar in the ears, and after falling a thousand meters, the wings behind the super spiritual suit spread out and landed safely.

This is a platform.

When we got here, the pressure doubled. If the two of them weren't physically strong, they would almost be struggling.

Divine consciousness is almost unusable here, and even Xia Nan can detect up to fifty meters away.

The panoramic map has also been greatly reduced. The radius distance of two hundred meters is equal to zero.

But even so, Xia Nan discovered through the panoramic map that the surrounding rocks contained metal with extremely high density.

It can be said that there is a huge metal deposit underground.

As the platform moves forward, there is a passage.

The passage is only nine meters high and six meters wide. Both sides are engraved with solid spiritual patterns, which become denser as you go deeper. Some abstract gods and demons are also carved in some places.

The passage is winding and twisting, like a winding dragon, and the temperature gets higher as it goes forward, as if there is a big furnace ahead.

"Master, that breath is very strong here, it seems to be emanating from the front."

Xia Bai said from the front.

After burning an incense stick, Xia Nan and Xia Bai walked through this long winding passage, and the scene in front of them shocked Xia Nan and Xia Bai.

At the end of the passage is a transparent light barrier. Within the barrier is a vast world of fire, with rolling magma underground, and huge ships parked in the air above the sea of ​​fire.

Figures fully armed and with wings on their backs were busy moving back and forth, drawing black arcs.

Battleship! War machine!

Xia Nan's eyes suddenly brightened.

Each huge warship is nearly 10,000 meters long, 1,000 meters wide, 800 meters high, and has an all-metal hull!

He could tell just from their appearance that these warships were more sophisticated and powerful than the magic ships he had captured in Daoyu Tianhe.

The number is a full nine hundred.

The dark metal is covered with magical and mysterious lines, and glows red and black under the firelight, making it look mysterious and heart-stopping.

Each battleship has ninety-nine magic crystal cannons with a muzzle diameter of ten meters.

If it can be obtained, it will definitely be a great weapon to kill the demon army.

Xia Nan licked her lips, with an excited look on her face.

Obviously, this is a base for building battleships!

Who built so many warships in this abyss?

Is this Falling into the Abyss not what the outside world has rumored? Or is the real function and purpose of this forbidden area to build war machines here?

There are no answers to these questions yet, and Xia Nan doesn't care much about the answers.

What he cares about is how to get these battleships!

Xia Nan looked at the barrier in front of her and pushed it. It was like a wall. She pushed hard and found that she couldn't shake it at all.

Then he punched him.

Bang!

A huge force bounced him away, and the huge rebound force almost hurt him.

"Master, let me try."

Xia Bai said.

Then he chopped it down with a knife.

Bang!

The greater the force, the greater the rebound force.

Xia Bai's tiger's mouth was shattered, and he and his knife were ejected.

Xia Nan squinted her eyes slightly, with some doubts in her eyes.

Since there is no way to enter the barrier here, why is a passage built?

Could it be that those red ants dug their own eggs out of idleness? Just to see the raging flames and the display of battleships inside?

Besides, he didn't think that with the wisdom of the red ants, he could carve so many complicated spiritual patterns on both sides of the passage.

Xia Nan's eyes flickered as she looked at the barrier in front of her, feeling that she might have overlooked something.

Then he turned around and said to Xia Bai, who almost fell down and gnawed on the mud after being hit by a knife, "Let's look around and see what else we find."

"Yes, Master."

The two of them walked back along the passage, carefully exploring and knocking around.

The passage is very long. It took half an hour to come in and two hours to walk back, but I didn't find anything.

In the end, the two discovered the mystery on a wall of the platform.
Chapter completed!
