Hei Niu didn't pay attention to the change in Gao Moli's subtle expression, and said excitedly: "I really have the intention to plant flowers that don't bloom, and I have no intention of planting willows and willows." Although there is no fourth gold plaque in the coffin of this old zongzi, there is a secret passage, and the credit for this great discovery must be recorded on my head. ”

The entrance to this secret passage turned out to be at the bottom of the coffin, and the sealing stone and the bottom of the coffin were integrated. It can be seen that this extremely hidden secret passage existed before the burial of the Yizhou assassin, and it was artificially set up here. It may lead to an important place, or perhaps the designers of the dungeon wanted to hide a secret that no one knows.

However, Gao Moli's expression changed slightly just now, and he may have noticed a trace of strangeness. I saw that the black bull had jumped into the black coffin, pinned the big black shadow to the backpack, and prepared to go down into the dark tunnel. Hurriedly stopped: "Don't be in a hurry!" Let's listen to Gao Moli's opinion first. I turned my head and asked Gao Moli, "Did you find anything?" Will this hole be connected to the outside world? ”

Gao Moli said lightly: "I'm not sure, I'll open the way." ”

With that, he wrapped the three-edged sword around the rope, carried it to his back, and Gu Zi got into the dark passage.

Looking at Gao Moli's reaction, it seemed that he was not sure if there was any danger in the cave. However, at the moment, we have no choice, and it is better to take a risk than to sit in this tomb and wait for death.

We went down into the dark passages one after another, and climbed down with our hands and feet. The tunnels seem to have been dug in a hurry, and there are raised rocks everywhere that you can step on.

After climbing down for five or six minutes, a cool breeze suddenly blew, and I found that the trend of the dark passage changed by 90 degrees here, extending horizontally forward.

I used the spotlight to shine in front of the dark passage, and I saw a faint green light in the distance, and the green light was like the moonlight shining on the leaves of the trees in the middle of the night, and the green was very beautiful.

Are we going out?!

Everyone couldn't help but get excited in their hearts, and they quickly climbed forward with enough horsepower. After crawling for more than ten minutes, we suddenly climbed out of the dark passage, and the front of us suddenly opened up.

The four of them stood on the platform at the dark entrance, lighting up two spotlights and a "wolf eye" one after another, and the three beams of light instantly illuminated the scene in front of them.

In front of us was a bottomless cave with a diameter of 100 meters. As far as the eye can see, the rock walls around the cave shimmer with green light, and the light beams make the fluorescence even more agile and bright.

The black bull's eyes were straight, and he swallowed his saliva and asked me: "Old Su, old Su, this seems to be a gem mine!" ”

I took a closer look at the green stone next to me and said, "I'm afraid I'll disappoint you, there are only glowstones in this cave, and the main component of fluorite is calcium fluoride, which often appears purple red, emerald green, light blue, etc., because it contains various rare elements." Even if it glows, it's just an ore, not a gemstone. ”

The black bull was puzzled and said, "Hey, no, Night Pearl, isn't it made of this thing?" A serious night pearl can also be sold for a lot of money in Panjiayuan. ”

I explained: "There are two kinds of fluorescence and phosphorescence, fluorescence refers to the light source can still emit light for a short time after the light source is irradiated, and phosphorescence belongs to the internal energy luminescence caused by rare earth ions, which can continue to emit light without the supplement of an external light source. Fluorite that can emit phosphorescence can be a real night pearl, so night pearls are rare and precious. ”

"This green light is so attractive, I'll get a piece and go back to make a Xibei goods, so that the buyer can't tell the difference." The black bull said, took out the big black eagle, knocked off a few bowl-sized fluorites and stuffed them into his backpack.

Gu Yixin saw that this was not outside the mountain, and said with a little disappointment: "It's another cave, I don't know when we can get out." ”

I comforted her: "It's better to be here than to be trapped in a tomb, and you see that this cave is full of fluorite mines, and fluorite often coexists with quartz, calcite, barite, agate and other minerals. In other words, this is already the boundary between the agate mine and other mineral deposits, and we have walked out of the agate mountain, at least without worrying about being burned to death. ”

Gao Moli was not in the slightest interest in the flickering green light on the cave walls, he sniffed the air lightly, and swept around the cave with his "wolf eyes", as if looking for something. Eventually, he froze the beam on the mountain wall to our left and told us to follow him.

Only then did I realize that there were steps on the mountain wall on our left, and the steps were carved out of the mountain, which was very narrow enough for a single person to pass sideways. If you don't look closely, it's easy to confuse them with the fluorite mountain walls. The stone steps spiraled down, and after more than three weeks of circling in the cave before stopping, there seemed to be a round bronze wrench on the mountain wall at the other end of the stone steps, and we were too far away to see it.

Although we are not afraid of heights, it is inevitable to walk on such a narrow stone staircase. We stopped and went, Gao Moli kept urging in front, and we walked for a full hour on the three and a half laps of steps.

At the end of the stone steps, there was a circular bronze door, the same size as the one inside the black sarcophagus. The difference is that this bronze door is not carved with a two-headed python, but a big snake shuttling through the clouds, this snake has only one head, its eyes are open, its mouth is slightly closed, and the snake face reveals a convincing majesty.

I don't have a crush on soft reptiles like pythons and lizards, but this giant snake on the bronze door makes me feel more intimate and friendly. I couldn't help but reach out and stroke the bulging head of the snake.

Gao Moli looked at me from the side, and stopped talking.

"There must be a secret passage behind this! I just don't know where this dark passage leads. Damn, the design of this dungeon is too complicated, and those undead will probably have to get lost if they slip around in their own homes. The black bull said, knocking on the bronze door, and there was a dull echo behind the round bronze door, and it seemed that there was really a secret passage.

I said to the black bull: "No matter where it leads, let's see the mountains open now, and see the doors open." Turn it on first. ”

After that, Black Bull and I were about to open the copper door, only to find that the copper door had no handle at all. We had to buckle the texture of the big snake and auspicious clouds, and tried to pull the bronze door out, but the bronze door seemed to be welded, and it didn't move.

The stone steps in front of the bronze gate are only two meters wide, and we don't dare to push too hard, for fear of falling into the abyss behind us if we miss.

"If this copper door is either cut corners when it is manufactured, or it is sincere, it doesn't want people to open it, and it doesn't even have a fucking handle!" The black bull said, pulling out the paratrooper knife and trying to insert it into the gap between the copper door and the mountain rock, but the gap was narrower than the blade and could not be inserted at all.

At this time, the bottom of the cave faintly sounded the sound of scratching the rock wall, and the sound was amplified by the cave, and it appeared extremely clear.
