In order to find out what was going on under the dark passage, Nie Zheng felt that he had to send someone down. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

Soon, he ordered everyone to prepare a rope tens of meters long, and at the other end of the rope, a hammer was hung, and then slowly hung into the circular secret passage.

After some measurements, it was confirmed that the rope could reach the bottom of the dark passage, and at this time, Nie Zheng ordered the five clone soldiers to descend into the dark passage in full armor.

After all five clone soldiers went down, Nie Zheng stood nervously next to the secret passage and waited for a response.

After waiting anxiously for half an hour, there was finally news from under the dark passage, and they told Nie Zheng that there was really a huge underground space under the square, and looking at the scale, it looked like an underground palace.

Hearing this, Nie Zheng's eyes lit up, and he was secretly overjoyed.

If there really is a hidden underground palace under the square, then the legendary seven-colored spirit fruit is very likely to be hidden there.

Because, after hundreds of clone soldiers explored in the city, they didn't find any suspicious signs at all, and as for the legendary seven-colored spirit fruit, they didn't see it even more.

There is no in the city, nor on the island.

Since there are no seven-colored spirit fruits on the ground, then you can only look for them underground.

According to Nie Zheng's perception of this strange world, no matter what kind of heavenly spirit treasure or rare beast, the place where they live must be very secretive, and then very bizarre.

It just so happened that now Nie Zheng had discovered the underground palace under the square again, so they had the direction to search.

After discovering the underground palace, Nie Zheng actually wanted to go down and explore it himself, but he was worried that there was something mysterious and terrifying hidden underground, so for a while, he didn't dare to take the risk himself.

He couldn't have run down until he was sure it was safe underground.

After thinking about it, Nie Zheng decided to send another group of personnel down, in order to strengthen the efficiency of the search, as well as the ability to defend against weapons.

Soon, dozens of heavily armed clone soldiers, once again, slowly descended the rope down the dark passage to the underground palace.

According to Nie Zheng's instructions, these people all carried a torch with them, waited below, lit all the torches, and then lit up the entire underground palace.

Nie Zheng wouldn't go down until he confirmed that it was safe below.

An hour later, the dozens of clone soldiers who were the first to enter the underground palace had already explored the entire underground palace, and basically, all corners of the underground palace were planted with torches.

Seeing that everyone was almost ready, Nie Zheng slowly climbed along the rope to the underground palace.

When his feet just touched the ground, he was shocked by the scene that came into view.

I saw that under the square, there was a very large underground palace, and if the scale of the underground palace was concerned, it was estimated that it was not much smaller than the palace on the ground where gold and silver treasures were stored.

This underground palace is about ten meters high and has a radius of thousands of square meters, and the architectural decoration inside is very simple, far less gorgeous and majestic than the palace on the ground.

At the same time, inside this underground palace, nearly a hundred stout stone pillars with three people hugging each other were erected.

The stone pillars are carved with many waves and waves, as well as dense fish scale patterns, and some stone pillars are also carved with some crooked and strange characters.

Look at the strange shape of those characters, it's very strange, it doesn't look like a font that humans have at all.

For the sake of safety, all the people who enter the underground palace wear gas masks, mainly because they are afraid that there are harmful gases in this underground palace.

Although Nie Zheng has swallowed the Dragon Python Neidan and is not afraid of any poison and miasma in the world, he does not dare to guarantee that the Dragon Python Neidan is really not afraid of any poisonous gas, and he is always relieved to wear a gas mask.

Nearly 100 torches stained with fuel were inserted into the walls around the main hall, the torches were burning, and the flames were constantly shaking and trembling, seeing this scene, Nie Zheng felt much more relieved.

Inside the underground palace, there must be a ventilated entrance.

Otherwise, if there was no air flowing inside, those torches would not have burned so violently.

Nie Zheng flashed a flashlight, and under the protection of more than a dozen clone soldiers, he cautiously explored the underground palace.

There was still some dampness in the dungeon, and in the process of walking, the damp ground was often trampled on with a "squeak", Nie Zheng leaned over to look at the ground and found that the damp ground was covered with a thick layer of dark black fish scales.

The scales are large, and each piece is semicircular, about the size of a coin.

Nie Zheng picked up a piece of scales, held it in his hand and observed it for a moment, and found that the color and shape of these scales were similar to the scales on those giant mermaids last night, but the volume of these scales was much smaller.

The scales should have accumulated in the underground palace for many years, and they had long been oxidized by the air, and with a slight twist of Nie Zheng, all these scales were shattered.

Seeing this scene, Nie Zheng frowned slightly, and secretly wondered: "How can there be so many scales piled up in this kind of underground palace?" Could it be that there is a mermaid hidden in this? ”

However, even if there was really a mermaid hidden in the underground palace, Nie Zheng was not afraid.

Because, judging from these scales on the ground, the volume of these mermaids should not be very large, otherwise, the scales would not be only the size of a coin, at least the size of a palm.

To be on the safe side, Nie Zheng ordered Jack to send some heavy machine guns out.

Although these clone soldiers all carry shotguns and AK47s, Nie Zheng is afraid that the power of these weapons is not enough, and he must strengthen his firepower.

In this way, the group escorted Nie Zheng, holding various arms and weapons, and cautiously touched towards the end of the palace.

As everyone gradually deepened, at this time, Nie Zheng was surprised to find that on the ground at the end of the palace, many mermaid bones appeared.

The bones of these mermaids are not very large, at most more than two meters long.

Nie Zheng walked up to one of the mermaid bones and took a closer look, and finally, he found that all of these mermaids had died unnaturally.

Their heads, chests, backs...... and some other key vital parts, all of which showed comminuted fractures, according to Nie Zheng's experience, these mermaids should have suffered a fatal blow before they died.

As they continued to go deeper to the end of the dungeon, at this time, the number of mermaid corpses scattered on the ground also increased.

In the end, on the ground within a radius of several hundred meters, a thick layer of mermaid bones was piled up, and the number was at least thousands.

Suddenly, a clone soldier ran up to Nie Zheng and said with a solemn expression: "Sir, the skulls of these mermaids have all been cut off by some sharp weapon, look at the fracture of their skulls......

Hearing this, Nie Zheng's face sank, and he hurriedly came to the pile of mermaid bones, and casually turned over a few of them to check them, and sure enough, as the clone soldier said, the mermaid bones in this area, their skulls were all broken into two.

The place where the skull was broken was flat and smooth, as if it had been cut off by some weapon that sharpened iron like clay before his death.

Seeing this scene, Nie Zheng secretly raised his vigilance, "Someone must have come in inside!" ”

Suddenly, at this moment, several more clone soldiers reported loudly: "Report sir, three human bones have been found here in the corner!" ”

"Human bones?"

Nie Zheng's heart moved, and he immediately ran towards the corner.

When I ran to the front of the wall, I saw that there were three human skeletons under the corner, leaning against the wall, although they had turned into skeletons, but the clothes they were wearing were not completely rotten.

At the same time, Nie Zheng was surprised to find that the hands of the three human bones were tightly holding three jet-black long knives.

The jet-black long knife was about four feet long and three fingers wide, and it looked extremely heavy.

Nie Zheng held the long knife in his hand, feeling extremely heavy, he stroked the blade with his fingers, and found that it was still abnormally sharp, and there was no sign of crumbling and curling the blade.

Seeing this scene, Nie Zheng immediately asked someone to bring a military dagger, and slashed it heavily at the blade of the long knife, only to hear a soft sound of "ding", and the military dagger turned into two on the spot, but the jet-black long knife had nothing to do.

"Shhh Nie Zheng gasped and secretly exclaimed, "Such sharp long knives, I really don't know how they are forged." ”

Turning his head to look at the mermaid bones piled up on the ground, Nie Zheng secretly guessed, "Could it be that these mermaid bones in the underground palace were all killed by the jet-black long knives of these three people?" ”

"Keep searching and see if there's anything else you find! Also, bring these three jet-black knives with you......"

Dozens of clone soldiers, holding thermal imaging search detectors, searched carefully in the dungeon again.

After some searching, they found a wall at the end of the dungeon that resembled a secret door.

Nie Zheng stood in front of the wall, flashlight and carefully observed the "secret door" in front of him, this secret door is five meters high, about four meters wide, the whole body is gray-brown, and the surrounding walls are closely connected, if it is not the color of the surrounding walls and it, it is really difficult to find its existence.

The entire underground palace had been searched by them, and nothing unusual had been found, except for fish scales and bones all over the ground.

It seems that in order to continue the investigation, this secret door must be opened.

"You guys search around and see if you can find any buttons or something......

After Nie Zheng's order, dozens of clone soldiers, all of whom used flashlights to carefully grope around the wall, but after groping for a long time, no one found a mechanism that could open the secret door.

Obviously, for this strange ancient civil engineering mechanism, Nie Zheng and the others are really not very good at it.

In desperation, Nie Zheng had no choice but to be ruthless, "Everyone put on protective earplugs and blow it up for me with a bazooka!" ”
