There was a loud bang!
The entire underground space vibrated.
The bomb carried by Wei Xingshan detonated, causing a small earthquake.
This result was obviously beyond Wei Xingshan's expectation.
No matter how big this place is, it is still a closed space. This kind of earthquake is extremely scary, making people feel like there is nowhere to escape.
Fortunately, after about ten seconds, the earthquake subsided.
Wei Xingshan lay on the ground and breathed a sigh of relief: "I was scared to death, I thought I was going to be buried alive."
"There was an earthquake here before." Yang Tuo was lying beside Wei Xingshan, and analyzed at this time, "You have completely ended that earthquake."
"Dr. Yang, could the previous earthquake be caused by explosives?" Anne asked.
"It's possible." Yang Tuo said, "Geological activities are very slow compared to humans. Earthquakes caused by geological activities will have a process when they release energy. Natural earthquakes, after the first earthquake, There will always be aftershocks. But in the previous earthquake, the Chinese side told me that no aftershocks were observed.
This shows that this earthquake was the result of a sudden change in the underground structure. After the energy was released this time, because there was no new external force applied, the underground structure quickly reached a new balance.
Captain Wei's pack of explosives broke this balance again, so the aftershock came. "
"Will it shake again?" Wei Xingshan asked with lingering fear.
"Probably not." Yang Tuo shook his head and stood up.
When the dust settled ahead, the four of them, led by Lin Shuo, came to the edge of the city wall.
Wei Xingshan's pack of explosives blew up a three-meter-square hole in the city wall here.
Anne turned on the flashlight and took a picture inside.
This place is on the edge of the Wengcheng, and the light of the flashlight shone in, only a street paved with bluestone was seen, with buildings of different heights on both sides.
There was no other light source inside, and it was pitch black.
"It's spooky." Wei Xingshan murmured, and walked in first.
This time Lin Shuo didn't hold him down and followed him in.
Once inside, everyone had an intuitive impression of the size of the city.
The flashlight followed the base of the city wall and swiped to the left and right, only to vaguely see the outline of the outer city walls on both sides.
"About three kilometers." Yang Tuo estimated, "If the length and width are similar, the size of this city is about the same as Kaifeng Mansion in the Northern Song Dynasty."
"Damn it!" Wei Xingshan exclaimed, "How big is this!"
Lin Shuo calculated in his mind and said, "About ten square kilometers is equal to one thousand hectares, which is bigger than a thousand football fields."
"Building such a big city underground, isn't it full of food?" Wei Xingshan shook his head, "Which landlord's stupid son did this?"
"The landlord's family can't afford to build this kind of city." Lin Shuo said, "The emperor's family is not far behind."
"Even if it's the emperor's family, it has to be in the heyday of the great dynasty." Anne also said at this time, "Generally, the small courts that are partial to security do not have such national power."
"The scope is actually not that big anymore." Lin Shuo said, "In history, there were only a few great dynasties whose territories included Heilongjiang."
"Tang, Jin, Yuan, and Qing." Anne counted the treasures on her fingers, and then took a flashlight to shine on the building next to her.
"Looking at the architectural style, it should be in the Song Dynasty." Yang Tuo said.
"That's Dajin or Yuan Dynasty." Anne nodded.
"Doesn't that mean that even a brick here is a treasure?" Wei Xingshan asked, "They are all antiques!"
"Isn't it?" Lin Shuo laughed, "Just because of your bombing just now, at least 100 million will be lost."
"My dear!" Wei Xingshan shrank his neck.
While talking, everyone walked towards the city.
Lin Shuo, who was leading the way, seemed to be relaxed, but he was actually in a state of tension.
For Lin Shuo, compared to the fern forest, the smell environment in this dragon city is much better, and there are not so many disturbances.
Therefore, he can clearly capture the breath of the hooked snake.
In addition to the smell of hooked snakes, the smell of Basnakes is actually stronger, but this is not because Basnakes are closer to here, but because this is the old nest of Basnakes.
This strange creature has been entrenched here for a long time, and the place is not ventilated, so its smell lingers everywhere.
Compared to the huge hooked snakes and barn snakes, the scent of Xiao Ba, a starling bird, was very weak.
If it wasn't for Lin Shuo being so familiar with Xiao Ba's smell, he wouldn't have noticed it.
In addition to the smell of these three strange creatures, there is also a smell of herbs wafting here and there.
Lin Shuo has been very familiar with this smell for the past few days. It is a kind of grassy smell here. It smells good, and it seems to have a refreshing effect.
It seems that a lot of this kind of grass has been planted in this city.
As I walked, a new smell appeared.
Lin Shuo twitched his nostrils twice, allowing more air to pass through his nasal cavity, carefully discerning the new smell.
"What's wrong?" Anne noticed Lin Shuo's expression.
"Listen." Lin Shuo said.
"Okay." Anne immediately leaned down and listened to the ground here.
"Someone." Anne listened for two or three seconds, and said, "It's nearby, five hundred meters to the northwest."
"It might be a missing person." Yang Tuo said.
"It may also be an ambush." Wei Xingshan reminded.
"Go and have a look." Lin Shuo waved his hand.
…
Liu Shunfu plunged into the Heilongjiang River and swam directly to the bottom.
As far as he knew, there were three secret passages leading from the ground to the Black Water Dragon City.
One of them was the main road when the Great Jin Dynasty built the Black Water Dragon City. It was a spiral descending passage similar to a winding mountain road. It was originally an ancient underground river.
According to legend, the bricks, tiles and ironware used to build the Black Water Dragon City during the Great Jin Dynasty were first transported underground through this road, and then used the underground waterway to reach the city site.
However, the exit of this road has been sealed by the Great Jin Dynasty.
The second one was made by the idiot Black Water Dragon King himself.
When I first arrived here, the winter was cold, and the Black Water Dragon King couldn't bear it. He chased the heat of the earth and drilled to the bottom of the river. After drilling, he drilled a way.
However, there is a large section of river water in the middle of this road, which is sealed and closed. People cannot swim in one breath, and they must suffocate to death.
The last secret path, which Liu Shunfu wants to enter now, is the masterpiece created by the ancestors of the Liu family a hundred years ago.
Liu Shunfu reached the bottom of the river, groped in the mud for a while, and finally touched an iron ring.
He adjusted his body, stepped on his feet firmly, held the iron ring with both hands, first twisted it 90 degrees clockwise, and then pulled it hard all over his body. With a "click", a large number of air bubbles rushed up.
A circular iron door was pulled open by him.
There are four arm-thick steel springs on the back of this door, otherwise, even if Liu Shunfu carries the inheritance and has a lot of strength in his hands, he will not be able to open it under such water pressure.
Through this door and into an airtight cabin, Liu Shunfu spat out half a mouthful of air bubbles. He knew that he was exhausted and the time to breathe was much shorter than before, so he stepped up his operations.
Close the door first, but not directly. Now the water pressure inside and outside the airtight cabin is the same, and the strength of the four springs is too strong to be resisted by manpower. The buckles of the springs must be loosened first.
After releasing the spring buckle and closing the airtight cabin door, Liu Shunfu twisted open a small door on the cabin floor.
"Clatter."
All the water in the cabin poured into the small door.
Below this small door, there is an underground river.
The water had gone down, and the old man leaned against the wall to take a few breaths, feeling his head swell.
In fact, the oxygen content here is very low, so we can't stay here for long, so Liu Shunfu hurriedly opened the door beside him.
Outside the door, there is a rope hanging down, looking down along the rope, the depth is bottomless.
Liu Shunfu covered his mouth and coughed a few times, and wiped the coughed up blood on his body.
"Stupid, you must be here!" Liu Shunfu said to himself, holding the rope with both hands, and slid down to the abyss underground.
