Sergeant Wong arranged for a police officer to drive a truck with a large searchlight to the scene.

Click!

The high-pressure xenon lamp is turned on, and the light with a range of 12 kilometers shoots straight into the pit. The people around the edge of the pit bent down in unison, followed the light source, and stretched out their heads to look down at the pit.

Twelve kilometers away, the light was engulfed in darkness and still had not yet bottomed out.

It's a deep pit. Everyone was amazed.

Everywhere the light source looks, it can be seen that the pit is circular with the same radius, and the walls are groomed and smooth, and it looks like a coat of painted wall paint.

Everyone agreed that it was a deep pit dug by hand.

A gust of cloudy wind, in the strong light, faintly floated up. Blowing head-on, everyone couldn't help but shiver and shrank back.

The strong white-red also shrugged his shoulders. He was very strange: there was no light just now, and there was no yin wind when he looked at the pit, but at this moment there was a gust of yin wind.

"Please turn off the lights."

Bai Hong bent down to look at the pit without light, and there was no yin wind.

"Please turn on the lights."

A cloudy wind rose again.

When the people next to him saw the mayor's move, they also stretched out their heads to look at the pit.

Turn off the lights and the wind disappears; Turn on the lights, and the wind rises again.

"It's weird." Everyone exclaimed, "Why is this happening? ”

"Have you arrived?" Bai Hong asked, "Immediately detect this pit." ”

"They're on standby." Sergeant Huang saw that Bai Hong had been observing the pit, so he didn't report their arrival.

The men of the geological team were replaced with high-pressure xenon lamps with more power.

Click!

The light with a range of 20 kilometers fell into the pit again, and everyone looked down together, but they did not see the bottom of the pit.

Once again, everyone exclaimed, "This pit is too deep." ”

"Please get out of the way, we're going to do it." "We use three of the test agents that are harmful to humans. You are safest when you stand five meters away. ”

The members of the geological team pulled up the isolation film, wore professional uniforms, and carried out the test in an orderly manner.

White and red they stood outside the diaphragm, eyes straight at them as they moved.

"Sheriff Huang!" Bai Hong whispered, "Did there be any abnormalities in this area before?" ”

"No, everything is fine." Sergeant Huang also replied in a low voice, "I have never seen anything abnormal, everything is normal." ”

"Is the Director of Construction back?" White-red asked their people, "The press conference should be over." ”

"Everybody's back." Someone answered.

"Let him come here."

"Yes!"

A minute later, the director of construction came to Bai Hong's side.

"Mayor! What do you command? ”

"Did anyone from the construction team report on the peculiarities of this area?" Bai Hong asked her, "Was it normal before?" ”

"Mayor! Everything was normal before, and nothing unusual was noted. Why did the walls suddenly collapse? And an extra bottomless pit? It's weird. ”

"Got it." Bai Hong said lightly, and never asked anyone else.

Everyone was silent, watching the people of the geological team inside the diaphragm busy with the work at hand.

The surrounding construction team, they also started work non-stop, cleaning up the site. The crying family members also left the scene with the intervention of psychologists. At the scene, only the staff remained. Journalists who wanted to take pictures and videos were asked away by the military in charge of security.

The entire area of the scene, from the land and the air, has been tightly enclosed, and idlers are not allowed to enter and observe.

The men of the geological team took off their professional clothing and put away the diaphragm.

"Mayor! All the indicators in the pit are normal, no toxic and harmful gases can be detected, and there is no abnormal soil quality. ”

"Got it. Go and take a break. ”

"Yes!"

Bai Hong instructed the army's expedition team to let them enter the pit to find out what was going on.

A quarter of an hour later, the army brought in various tools for the expedition and piled them up on the edge of the pit.

The two team members wore expedition suits, and the other personnel operated the machine, erected a lifting platform and nylon rope, and equipped a micro-drone.

Everyone tugged at each other's hearts and watched as the two explorers walked into the lift.

Click!

The lifter turned on and the lift slowly sank. Micro-drones have gone down in advance.

The person standing on the edge of the pit felt that the yin wind was stronger, and his heart was tightened. In addition to the army, the people stick to their posts as always; The people around the clean-up site stopped what they were doing, and everyone gathered around.

Everyone stared at the screen above the lift, watching the two slowly descend. The faint wind clearly shows on the screen, blowing the eyebrows of the two of them.

The pace of time has also slowed down, so slow that everyone's hearts are tightened, and they are very anxious.

Bai Hong couldn't help clenching her fists, her palms sweating.

In the video: The walls of the pit are smooth all the time, and there are no bumps or depressions in any place; The yin wind blew the eyebrows of the two of them tighter, and even the expedition suits fluctuated slightly.

People watched with bated breath.

The cleaning machine, which did not turn off the power, was particularly loud with all kinds of noises, and it was not at all affected by the dull atmosphere at the moment. The robot only looked at the silent crowd and buried its head in the work at hand.

Gurgle, cluck!

The lifting platform sounded the sound of falling.

Each heart beats to the same rhythm, and I feel like I'm the one in the lift. The yin wind drilled into every cell, trembling.

Beads of sweat oozed from everyone's palms, frowning, and tensing muscles.

"Mayor!" Sergeant Huang stared and said, "The two of you have descended to 20 kilometers. ”

"Hmm!" Bai Hong's eyes kept staring at the video, "This pit is too deep." ”

Everyone present tightened their minds, staring at the timely footage that came back from below.

The depth of this pit, which seems to have no bottom, extends far away. Everyone feels that they are in endless darkness, there is no light in the world, and layers of depression are rushing to their faces.

"Call the podium! Call the podium! ”

A cacophony came over the intercom, breaking the silence of the crowd, and everyone moved.

"Command platform received! The podium received! Please! ”

"The bottom of the pit has arrived!"

"Roger!"

The depth of the pit is shown on the screen: twenty-four kilometers. No more, no less, with a depth accurate to "24".

Every hanging heart seems to have taken a reassuring pill and the body relaxes.

"There's nothing unusual down there, just like above."

You can see it on the video: the bottom of the pit is also smooth, and there is not a trace of bulge or depression. The pit was so perfectly formed that it looked like a long clinker bucket had been inserted into the ground.

A natural pit quietly appeared within the city walls.

Bai Hong tossed and turned, unable to sleep, thinking about this pit all the time.

A large area of the city wall collapsed, but the pit was not affected in the slightest, not even the wall and the bottom of the pit could see the ash layer, nor the forks, wild beasts, human figures, etc.

Manual excavation? Or is it naturally occurring? What does this pit have to do with the collapse of the wall?

He was eager to find the slightest connection, to find out why the walls had fallen. However, people from all departments were dispatched, but they couldn't find the reason.

Bai Hong looked out the window at the night, turned over again, and continued to think about the collapsed walls and pits.
