"I don't think this arrow is like some hidden thing, it's better to touch it less, if it's poisonous, it's over. Tom reminded.

But as soon as he finished speaking, the arrow was directly twisted by Nari, to be exact, this arrow seemed to be really only two pieces, this twist, two sections came out.

Everyone looked at each other in disbelief.

At this time, Ning Xiaofan suddenly thought of something, he immediately went over, took the part of the arrow shaft that was unscrewed, and inserted it directly into the hole of the relief.

The difference this time is that it was inserted in one fell swoop, there was no obstacle, and the shaft of the arrow matched the size of the hole perfectly.

That said, it's really possible that this is the key to opening the wall door.

After insertion, Ning Xiaofan held the arrow shaft, turned it counterclockwise at 360 degrees, and sure enough, he only heard the sound of the doctor's heavy giant gear turning, and then, the wall door in front of him slowly rose up!

After the wall door was opened, everyone was shocked, inside was a cave whose size suddenly widened, and it was necessary to go inside, but the interesting thing was that on the walls on both sides of the cave, there were actually oil lamps.

This made everyone dare not move forward for a while.

"Is there anyone here?" said Tom quietly.

He really couldn't explain the matter of this lamp oil, if it was said that this was a secret passage made by the people of country M 100 years ago, he would have believed it, but now that this lamp oil has appeared, how can he say it? Let him believe it? Not to mention that the lamp oil has been burning for a hundred years, can it burn for a day? If he is not mistaken, there must be someone here.

Who will it be?

Not just Tom, but everyone else thought the same way.

"Not necessarily. Nari said lightly: "When I was in the Hungry Wolf Gang, my father once told me that there is indeed a kind of lamp oil in this world that can burn forever, and he didn't tell me that much detail at that time, but I believe that since my father mentioned such a mouthful, there must be a basis." Everything in this world is full of wonders, don't be too surprised. ”

Na Li's calmness once again refreshed Ning Xiaofan's cognition, it was unbelievable that an eighteen-year-old boy could say such mature and rational words.

"But ......" When Tom wanted to refute, he was interrupted by Ning Xiaofan waving his hand: "Don't worry, let's go first and take a look, even if there are people, we still have guns in our hands, it's not worthwhile." ”

"That's right. Tom thought about it and felt that what Ning Xiaofan said also made some sense.

Nali is still at the forefront as always, after a short period of contact, Ning Xiaofan found that this Nari is not only very mature, but also she has great curiosity and bravery.

This kind of girl is really rare, at least Ning Xiaofan is so big, it's the first time I've seen it.

As I walked, suddenly there was a sudden light ahead.

There seemed to be a light, and it was also this sudden light that made Ning Xiaofan and the others immediately cautious.

Is it really like Tom said, there are people in it?

But after walking over, Ning Xiaofan and the others were all dumbfounded, there was not the slightest figure here, but there was a very large palace, at least hundreds of square meters!

In the center is a huge altar flanked by statues that look like gods, and at the front of the altar there is a throne on which a man sits with a spear.

Although this person is a sculpture, because the carving is lifelike and very well preserved, it really looks like a real person!

"Oh my God......! It's a huge altar, how could there be any of these things?" exclaimed Tom.

The others were also shocked by what they saw.

When Ning Xiaofan saw this scene in front of him, he felt that he was in a novel where the ghost blows the lamp, which is really incredible.

Nari was also surprised, but her face did not show any shock, her face was as calm as ever. She walked to the wall next to the palace, and she used a flashlight to shine it directly, just now because the dim light of the oil lamp was too low, so it didn't show what kind of content was on the wall, but as soon as the strong light hit, all kinds of strange patterns on the wall immediately appeared.

Tom was immediately stunned when he saw the pattern on the wall: "Oh my God, this is ...... This is the scene of the War of Independence of Country M! Look, this is HSD! Oh my God, what is this palace recording? War of Independence! This is the history of Country M!

He called everyone to stand in front of the wall and began to look. Not only is the pattern on the wall in front of Nari recording the content of the period of the independence war of country M, but the other pieces are all like a complete picture, like a comic book.

Ning Xiaofan took a look at it and found that at the beginning, it was Columbus who led the ships to discover the scene of the new continent of North America, to the later war of independence of country M, etc., and even the first world war later. The pictures on the walls are extremely vivid images of this sequence of scenes.

It's as if a scene of history is happening right in front of you.

Ning Xiaofan is not from country M, but he has studied history, and Ning Xiaofan is no stranger to this.

"If I'm not mistaken, this is probably a record of people living in this cave before the First World War, you see, although they are all very well painted, but the style is completely different, and there are clear boundaries at different events, that is, people from different periods. Nari said.

"No, if it was painted by people from different periods, then why are they all painted so well? That's, isn't it? Tom was a little unconvinced, "I think this must have been painted by people who came here during the First World War." After all, in the early history of country M, as long as you are a person from country M, you know that this is nothing, it is this painter, and he does have a hand. ”

"There's no point in arguing about this now, I now want to know what this altar is for, who are the people on this throne, and why do these people carve the history of country M on the wall?"

"I don't know. Tom shook his head.

At this time, Nari was frowning.

Ning Xiaofan felt that she should have seen something, and following her gaze, she found that next to that throne, there were actually several large treasure chests, just like the kind of large chests loaded with gold, silver and jewelry in ancient times.

Ning Xiaofan's pupils dilated instantly, intending to take a look at what was in this box.

But this look stunned Ning Xiaofan, it was really gold and silver jewelry, and it was all gold!

Huang Cancan, as long as it is opened, it will inevitably emit a golden light!
