Yu Fei and the others did not have many bullets, so as long as the monsters did not impact the entrance of the passage, they did not dare to shoot casually, and the two sides were at a stalemate for a while.

At this moment, everyone suddenly felt that the earth was trembling slightly, and then there was a "rumbling" sound at the entrance of the passage, and before everyone could react, "Bang! With a loud bang, a huge and heavy stone slab fell, smashing the entire passage as if it were shaking, but it sealed the entrance of the passage tightly, and those monsters were naturally blocked out of the stone slab.

"Why did you suddenly fall such a big stone slab? Looks like I'm afraid of a ...... of one or twenty tons."

"Could it be that someone hit the mechanism? Let's take a look! ”

"Everyone be careful, if there is a mechanism, it can't be the only one, don't touch anything you find, so as not to touch the mechanism!"

Everyone in the archaeological team reacted quickly after being surprised, and they all got up and carefully searched for possible mechanisms, for fear that someone would touch the mechanism again and bring some unpredictable danger to everyone.

And after Xiao Rong gave Yu Ling'er and Ah Rishan a very vague look, the three of them quickly lowered their heads and pretended to find something, in fact, the three of them were secretly snickering in their hearts at this time. Where is there any mechanism, the big stone slab was just made by Xiao Rong in order to block the pursuit of the monsters, and secretly communicated with the power of the earth, but it was deliberately made like this in order to hide people's eyes and ears.

Everyone searched carefully for a long time, and searched the entire passage almost inch by inch, but they did not find any traces of the mechanism, and they were puzzled. I had no choice but to give up the search. After a short break. The crowd set out again. Head along the passage.

The passage is dark and cold, giving people an inexplicable sense of fear, but fortunately, the archaeological team has been doing this kind of work all year round, and they are all a little used to it.

After about a quarter of an hour, a faint white sheen in front of us caught everyone's attention. Although the white light was faint. But in this dark passage where you can't see your fingers, it's still as conspicuous as a lighthouse.

After moving forward for about a hundred meters, the white light in front of them became extremely obvious, everyone turned a corner, the white light suddenly became stronger, and the sudden white light made everyone's vision slightly uncomfortable, and even unconsciously closed their eyes. However, when they opened their eyes again, everyone couldn't help but lose a little color, and their faces were full of shock.

It was dozens of meters in front of where they were standing. It's another cave, though slightly smaller than the one full of monsters outside. But it is also an extremely open space, and the huge karst cave is presented in its complete form in the shape of a cone. Amazingly, the stone walls of this cave are smooth as mirrors, reflecting a faint white light, giving people a sense of unreality that is dead but dreamlike.

Nearly three-quarters of the area in the cave is water, and only the middle position is exposed to the ground, accounting for a quarter of the entire cave area, and the water in the cave does not know where it comes from, it is not a pool of stagnant water, it has been flowing slowly.

But this was not the most shocking, the most exciting and incredible thing was that they saw a tall tower on a small island in the middle of the cave, which was the goal of their trip.

It is a seven-story tower, the total height is fifty or sixty meters away, the style is simple, seven floors, four sides, eight directions, the spire exudes a rich white halo. It was a tall white tower that seemed to be filled with dead silence and terrifying energy fluctuations.

This tower is located in the middle of the small island and at the center of the entire cave, occupying most of the entire island. Layers of faint white light continued to spread from the spire of the tower, and the powerful energy fluctuations made Xiao Rong, Yu Ling'er, and Ah Rishan, who were superpowers, all have a trembling and fear from the bottom of their hearts.

Xiao Rong glanced at it quickly and covertly, and sure enough, he found that the expressions of James, Jessica and Johnson had also changed, and then they covered up the past very well, turning into the same excitement and shock as everyone else.

"Captain, here's the way to the island." An armed police soldier shouted not far away, waking up the people in shock, and everyone hurriedly gathered around.

It is said that it is a road, in fact, it is just a little bit of stone piles exposed to the water, the cross-sectional diameter of the stone pile is about 30 centimeters, the distance between the stone pile and the stone pile is about seventy or eighty centimeters, which is exactly the span of one step of an adult, but the water splash on the stone pile is wet and wet by the water flow, very smooth, and it is still difficult to step on these stone piles across the water surface of dozens of meters.

"Xiao Lu, Xiao Qi, you two bring the rope to pass first, fix the rope after passing, and then the others will follow the rope." Zheng Shuxin thought about it for a while, then had an idea and said, "Go ahead, pay attention to safety!" ”

"Yes!" Two young armed police soldiers tied one end of a large coil of rope to their bodies, and carefully and steadily stepped on the stone stake towards the island. When he walked about two-thirds of the distance, Xiao Qi accidentally slipped and fell into the water, but in the exclamation of everyone, he saw that he did not panic, swam forward with all his might, and even landed on the shore one step earlier than Xiao Lu.

After Xiao Qi and Xiao Lu landed on the shore, they quickly fixed the rope firmly, and Zheng Shuxin also fixed the rope on a thick and sturdy stone pillar and built a rope bridge above the water.

Next, with the help of the armed police soldiers, the archaeological team fastened their safety belts, and the safety buckles on the safety belts were buckled on the rope bridge, and they carefully stepped on the stone stakes and marched towards the island. When Li Yaping, James, Jessica, and Yu Ling'er crossed over, they were followed by an armed police soldier for protection.

In this case, there was no danger in the process of crossing the water, and after more than an hour, more than a dozen people finally landed on the island one after another, only a few people were wet when they accidentally slipped, but no one was injured.

However, when everyone landed on the shore, they were deeply shocked by what they saw. What is that? Dry bones, dry bones everywhere, no, skeletons, skeletons with very complete skeletons, dense and neat.

There is a distance of hundreds of meters from the shore to the tall ancient tower, and the ground at this distance of hundreds of meters is all paved with huge bluestone slabs that are smooth and flat, forming a regular square. (To be continued......)
