As the secret door blocking the entrance to the corridor was broken through, a stream of foul gas immediately spewed out from the corridor.
Fortunately, Matthew and the others were well prepared and wore gas masks, goggles and other equipment, so they did not suffer any harm.
Even so, they were still startled and couldn't help but move back.
Immediately afterwards, Matthew immediately began to report the situation.
"Sean, it seems that you are right. There is indeed a lot of dirty air accumulated in this underground space."
"From this point of view, this underground space should be in a completely sealed state, with no vents connected to the ground."
While talking, Xiao Ran had already reached the edge of the pit.
He also wore a gas mask and other protective equipment and was safe.
After standing at the entrance of the pit, he looked at the situation at the bottom of the pit, and then said with a smile:
"Guys, don't rush to explore with the endoscope probe. First, replace the dirty air in this underground space."
"After replacing the air in the underground space, use the endoscope probe to explore. This is safer, so be careful."
After hearing the instruction, Matthew and the others immediately nodded and responded:
"Understood, boss, we will be careful"
Matthew and the others responded in unison.
Then these guys took action.
Immediately afterwards, two powerful fans were hoisted to the bottom of the pit.
Then through two hoses, the dirty air in the underground space behind the secret door begins to be replaced.
It took about fifteen minutes for the air in this secret space hidden deep underground to be completely replaced.
A large amount of dirty air extracted from this underground space was discharged into the air and dissipated with the wind.
Instead, fresh air is injected from the outside.
After replacing the air in the underground space, Matthew and the others took out the endoscope probe and started the next step of exploration.
The endoscopic probe they used has a bright flashlight and a high-definition camera on the front, which can perform exploration tasks in dark environments.
Moreover, the probe can turn in any direction, there are no dead corners, and it is very convenient to control.
After turning on the light and high-definition camera of the endoscope probe, an exploration team member slowly extended it into the cave and began to explore the inside of the underground tunnel.
As he moved, the images captured by the high-definition camera appeared simultaneously on the iPad in Xiao Ran's hand.
At the same time, these pictures also appeared in several live broadcast rooms.
The first thing everyone sees is a drilled hole about five centimeters in diameter.
As the probe continues to extend inwards, the video picture is also changing.
In a moment, the endoscope probe had passed through the newly drilled hole and entered the tunnel.
What then appeared in front of everyone was an underground world completely shrouded in darkness.
The light at the front end of the endoscope probe was like a thin sharp sword, piercing the darkness.
But unfortunately, this light is very thin and the distance it illuminates is limited.
I still can't see clearly what's going on deep in the corridor.
At this moment, Xiao Ran suddenly said:
"Don't worry about the depths of the corridor. First explore the situation behind the door. Be careful when exploring."
"Okay, boss"
The guy operating the endoscope probe responded.
Under his control, the endoscope probe began to slowly turn and shine towards the left side behind the door.
As the light moves, everyone can see that there is nothing on the left side of the stone gate, and no control mechanism can be seen.
Next, the endoscope probe slowly rotated in a circle and explored the surrounding area of the drill hole.
The result was the same, still nothing was found.
The inside of this stone door is empty, with nothing, just like the outside.
"Guys, extend the exploration distance and mainly look at the walls, the ground, etc. on both sides."
"If there is nothing in these places, we can cut through this reinforced concrete door."
Xiao Ran's voice came out again.
Following his instructions, the exploration team members controlling the endoscope probe immediately took action.
He inserted the tube of the endoscope probe into the borehole bit by bit, and then controlled the endoscope probe to extend to the left wall of the corridor to conduct further exploration.
In a moment, the endoscope probe had been extended to the left wall of the corridor.
At this moment, Xiao Ran suddenly said:
"Stop! Do you see the black shadow on the wall on the left? Shine a light on that thing. It looks a bit awkward. Maybe it's a trap."
"I saw that thing, Sean"
The guy operating the endoscope probe responded.
The next moment, he controlled the endoscope probe to shine there.
When the light shined on the black shadow, everyone could see clearly.
It was a rusty thing, about 30 centimeters wide and 20 centimeters high, tightly attached to the left wall of the corridor.
Because its surface is covered with rust and the light is dim, it seems to be integrated with the wall at first glance. It is not easy to spot if you don't look carefully.
The first time they saw this thing, many people didn't recognize what it was and were very curious.
"Xiao Ran, what is this thing? It looks like a rusty iron lump."
"Since this thing is arranged at the entrance of the underground corridor, it should not be simple. Otherwise, Lu Qinzhai wouldn't have spent this effort."
Everyone started talking, all confused.
The next moment, Xiao Ran suddenly said in a deep voice:
"If I read it correctly, this should be a Hawkins anti-tank mine from World War II. It is a mine shaped like a hip flask and specially used to deal with tanks."
"In the famous movie, "Saving Private Ryan," the anti-tank mines placed on the bridge appeared in the scene of guarding the bridge. The power is quite amazing."
"If it is really the Hawkins anti-tank mine, Lu Qinzhai placed it on the wall at the entrance of the secret passage, which is obviously a very smart and ruthless approach."
"If someone breaks through the walls on both sides of the corridor, it is likely to trigger the anti-tank mines placed on the walls on both sides, or even trigger a more powerful bomb."
"Then it can blow up the entrance to the secret tunnel in an instant, burying the tunnel that leads deep underground, and it can also blow up the people outside who are trying to dig out this underground tunnel."
"hiss"
Everyone took a breath and was shocked by Xiao Ran's words.
Especially Matthew, who had just suggested demolition from the side of the corridor, felt a chill coming down his back and was terrified.
They knew that if Xiao Ran had just adopted their suggestion and demolished it from the side of the corridor, the consequences would have been disastrous.
At this time, they might have been killed by the anti-tank mines placed in the corridor.
After a brief shock, many fans in the live broadcast room immediately began to search for the Hawkins anti-tank mine and compared it with the thing in the corridor.
Within a short time, many fans had discovered it and started talking about it.
"This thing is really like a Hawkins anti-tank mine, except that the outside is completely rusted. Even if it is an anti-tank mine, will this thing still explode after seventy or eighty years?"
"This is a landmine! It is detonated with a trigger fuse, not a simple package of explosives. Even if it is rusty like this, it is still very deadly. The rust on the surface may even be more lethal."
While everyone was talking about it, Anthony, who came up to check the situation, also gave a positive answer.
"Sean, your judgment is very accurate. This is indeed a Hawkins anti-tank mine from World War II. It is incredibly powerful."
"If there are many such anti-tank mines in this underground tunnel, you must be very careful when exploring next."
Xiao Ran smiled and nodded, and said confidently:
"Now that we have discovered this thing, they are no longer a threat!"
