?“ Mr. Chen, I only know about the existence of this Bohai Palace, and I can even say that I don't know as much as you know, so I can't provide you with any information here, everything can only rely on you, remember, we must leave here before the heavy snow closes the mountain, otherwise we will be trapped and die in this mountain together. ”

Xiao Na said this made Chen Ziyang feel very surprised, but it seems that this Xiao Na should be telling the truth, otherwise, she will definitely tell herself about the relevant information of this Bohai Palace, which will help speed up the search for the Bohai Palace, Xiao Na has no need to hide. It's just that Chen Ziyang couldn't figure out where this Xiao Na knew about the existence of the Bohai Palace.

Since there are no new clues to add, everything can only rely on his ability to find the dragon point, because there is no magnet pillar here, Chen Ziyang's compass can be used as usual, so he continued to look forward along this arc-shaped mountain range.

Chen Ziyang had searched this mountain range before, but he didn't find anything special, this time he was more careful when searching, for fear of missing some clues, and the heavy snow on the ground undoubtedly added a lot of difficulty to finding the entrance to the Bohai Palace.

This arc-shaped mountain range is about ten kilometers long, and it is just right to go back and forth in a day on this kind of snow, and two days have passed, Chen Ziyang has walked here twice, but he still has not found any clues, and even he wonders if the entrance to the Bohai Palace he is looking for is wrong.

On the third day, Chen Ziyang and Yang Lei, along with the four soldiers who were guarding them, set off again. This time the search was more careful, walking more slowly, the time came to noon, they walked to the middle of the mountain range, while having lunch, Yang Lei was attracted by a snow rabbit, hurriedly chased over.

But Yang Lei not only didn't catch the rabbit this time, but also fell a big heel and rolled down a snow slope, and when he slowly climbed up, there was still some distance from the rock wall, and found that there was a place on the stone wall in front of him that looked different in color from the rest of the stone wall.

Yang Lei hurriedly shouted and told Chen Ziyang this information, but Chen Ziyang, who was standing under the stone wall, did not find anything abnormal about the stone wall, so he ran to Yang Lei, and the two of them watched from a distance together. Sure enough, standing here and looking at Yang Lei, Chen Ziyang found that there was a darker color on this stone wall, and the shape seemed to be a crack in the mountain.

It's just that this crack can only be found to be different from other places when you look at it from a distance and the angle of the sunlight is different. This is really a fan of the authorities, and the onlookers are clear, and they can't imagine that a snow rabbit has helped so much.

The two of them hurriedly remembered the location of this crack, and then walked under the rock wall, and used the tools in their hands to knock on the position of the different colors on the stone wall, and sure enough, they heard a rare echo inside, and they didn't think that this mountain wall was filled in later, and they didn't know what materials the craftsmen used, the backfill was not only very strong, but the color was very close to the stone wall, if it weren't for Yang Lei's accident, he wouldn't have found it at all.

took out the compass, Chen Ziyang looked left and right, this stone wall is exactly located in the center of this circular mountain range, from this position you can see the left and right ends of this mountain range, just in line with the pattern of the left green dragon and the right white tiger, it seems that this is here.

Chen Ziyang told the accompanying soldier about the discovery, and then the accompanying soldier informed Xiao Na on the walkie-talkie. After a while, Xiao Na and Wang Dawei walked over with two people, and one of the soldiers, after observing the surrounding terrain, confirmed that explosives could be used and would not cause an avalanche.

After the soldier expertly picked up the C4 explosives on the stone wall, several people hid aside, and after a loud bang, the hidden crack in the mountain was revealed by the effect of the explosives.

When the smoke cleared, several people leaned forward to take a look, and the crack was roughly similar to the one they had set up camp on, except that it was wider and deeper. Under Xiao Na's order, Umbrella Shishuai and Yang Lei took the lead, and the others followed behind them, slowly walking inside.

This order made Yang Lei roll his eyes in anger, didn't he say cooperation? How do you feel that you are here to die. But under the muzzle of the black hole, they also had to grit their teeth and move forward.

The width of the crack is roughly the same, allowing four or five people to walk side by side, this crack should run through the entire mountain, looking up from the bottom of the crack, you can vaguely see a few rays of light from the top of the mountain. The crack is not perpendicular to the mountain, but is inserted diagonally into the mountain.

The group walked along the crack to the interior of the mountain for about 200 meters. Then Yang Lei and Umbrella Shi Shuai discovered that in front of them, there was something like a huge stone disc. At the same time, because of the angle problem, Umbrella Shishuai found that inside this stone disk, there was a huge stone door. After confirming that there was nothing unusual around, Xiao Na's men stepped forward and carefully observed the stone gate.

"I said Eryang, whose family stone mill is this, this grinding disc is so big, if this is to grind soy milk, how many people will have to drink." Yang Lei saw that there was no danger in front of him, his nervous heart relaxed, and he began to be poor again.

Everyone else was studying the stone gate, but Chen Ziyang was reminded by Yang Lei's words and looked carefully around this huge stone plate. This stone plate is very huge, the diameter is about seven or eight meters, I don't know how heavy, the surface of the stone plate is very smooth, there are deep circular holes on the side every certain distance, I don't know what it is for.

At the same time, Chen Ziyang carefully looked at the seam between the stone plate and the mountain, and he found that the middle part of the back of the stone plate seemed to protrude, and this part went deep into the interior of the mountain. Moreover, the bottom of this stone plate is dozens of centimeters away from the ground, and Chen Ziyang came up with an idea, it seems that this stone plate can be rotated.

At this time, Chen Ziyang heard the conversation between Xiao Na and Wang Dawei, and Wang Dawei confirmed that this should be the entrance to the underground palace of the ancient country of Bohai, because the patterns and textures on the stone gate are very consistent with the historical characteristics of the time, and I can't imagine that this Wang Dawei still has archaeological knowledge.

Then the soldier who blew up the crack in the mountain before put a large amount of C4 plastic explosives on the stone gate, and after connecting the line, everyone clinged to the stone plate one by one, leaning against the mountain, to avoid the impact of the explosion. After a loud bang. Xiao Na and the others hurriedly stepped forward to check the damage to the stone gate, and at this look, several people were startled, only to see that the stone gate was still standing there intact.

The explosives that used to blow up the cracks in the mountain were like blowing up a piece of tofu, and they didn't have the slightest use for this gate, but the explosion blew some of the dirt off the surface of the stone gate. A few people stepped forward to see that the whole door was all made of fine copper, and I don't know how thick it was, and the explosives couldn't make the stone door slightly deformed, so it seemed that the method of opening the door with explosives would not work.

So Xiao Na turned her gaze to Chen Ziyang again.
