Before, in order to increase his own value, he deducted some important details, this kind of performance Bai Ning obviously didn't like, he had already made a mistake, and now he was about to explore a more dangerous place, Ivan felt that he should be more cautious.

The water filled the lake until the evening, and by the last rays of light, the damp bottom of the lake was exposed with rocks except for a little silt on the shore.

Nowadays, the spiritual pollution of the core explosion area still has no tendency to weaken, and the core area of the ancient ruins is obviously not affected by the lake, and its underground area is far larger than everyone imagined.

Underground cavities and underground people have always been some topical gimmicks, and they occupy a place in urban legends.

In such a vast area, those strange creatures that once escaped from the ancient ruins are most likely not kept in captivity in the experimental area, but may be stocked in a vast open area.

Not only is the area open, but it even contains a vast ecosystem that supports the daily survival of these animals.

The light source of the huge underground space, which has always been the most fantastical setting of the underground civilization, I don't know what lighting equipment is used in this huge ancient ruins.

Without the protection of the embedded explosives, the outlaws seemed to be more hesitant at this time, they couldn't sleep in the first place, and the conversation between them was more inclined to the future exploration of the cave bottom.

The process is so dangerous that the excitement isn't really high.

Death may not be what outlaws fear, and the unpredictable death in a painful environment is what outlaws fear the most.

Bai Ning ignored these inevitable restlessness, and the most important thing at the moment was to find out where the cave under the crater led as soon as possible.

In the middle of the moon, the sound of water in the crater finally stopped, the night was a little quiet, and the raging flames by the lake still could not touch the tunnel in the center of the crater, and it was pitch black, like an eternal nightmare that could not be touched.

Bai Ning took Ivan and the others to hold the searchlight and slowly touched it, the slope was very steep, the slippery ground made everyone very cautious, and the steep slope of several hundred meters walked for more than ten minutes.

When they arrived near the deep pit, the hole with a diameter of more than ten meters lay in front of everyone, and the crowd that gathered seemed extremely small.

The expected darkness was endless, and a breeze mixed with an unknown smell slowly poured out of the mouth of the cave, proving that there was indeed a cave in the underground space.

He picked up a stone that had been prepared and threw it down, and there was so much silence that it was impossible to judge how deep the downward passage was.

"Are you going down now?"

Jiang Yingxue threw the strong flashlight in her hand down the deep well, and the pillar of light swirled and fell quickly, and soon disappeared into the darkness.

Such a bottomless cavity aroused the desire to conquer in Jiang Yingxue's heart, and forcibly suppressed the stinging pain in her mind, Jiang Yingxue asked as calmly as possible.

Bai Ning didn't respond, just waved his hand and signaled Ivan to start organizing people to build a rappelling platform.

In a short time, the personnel of the first wave of downward exploration have been equipped, and after reaching the limit of 100 meters, they can build their own relay platform.

They are all good hands, even if the state of the rappelling personnel is very poor, their skills are still vigorous, and soon they came to the extreme depth, flashed a few strong flashlights upwards, and there was bottomless voice feedback from the walkie-talkie.

Without the slightest hesitation, more personnel descended rapidly with more equipment, and this huge descending tunnel was like a gluttonous esophagus, which was endlessly devouring the few remaining manpower in the camp.

When it was almost dawn, the last group of people also descended one after another, and only Bai Ning and Jiang Yingxue were left on the edge of the deep pit.

"Ivan, how much rope equipment do we have in our hands now."

Now that the cave has been explored more than a thousand meters down, all the outlaws in the camp are clinging to the cliff like ants, and many of the tired people even hang on the ropes and fall asleep.

The personnel at the lowest level want to climb up again, and it has become a luxury at this time, such a desperate situation, once they encounter any risk, they may be completely wiped out in the underground space.

"It's not much, but you can continue to set up three relay points downwards at most.

With such a deep lower cavity, I don't know who dug it out. ”

The scale of the ancient ruins in the Tunguska region amazed Ivan, and he didn't have any confidence in whether he could officially enter it.

"I've already contacted the logistics staff, and they're working hard to set up a transit station, and the first batch of supplies will arrive in three days at most."

Now that the ancient ruins are beginning to see, Jiang Yingxue also has more sufficient reasons to allocate a large amount of funds to support subsequent exploration.

For Bai Ning at this time, he was more concerned about the issue of time.

The spiritual contamination of the ancient ruins may be even stronger, and their time here is extremely limited, and it is a question of whether they can wait until the first supplies arrive.

"Can you find some bigger transport planes and let them find a way to airdrop a batch of supplies here?"

Bai Ning's rhetoric was very tactful, and what he said was the military transport plane, this kind of request made Jiang Yingxue embarrassed, but she did not directly refuse.

"I'll try."

After being silent for a long time, Jiang Yingxue just gave an ambiguous response, to which Bai Ning only assumed that she agreed.

After a few hours, all rope equipment was exhausted, and the team finally reached a depth of 1,365 meters, where the outlaw hanging at the very end looked down with a flashlight, and it was still pitch black.

In this endless cavity at both ends, the feeling of insignificance in his heart made him feel at a loss, and an urge to jump off flashed in his mind.

In the next moment, the outlaw seemed to see his body fall silently.

The heat of over forty degrees Celsius made the outlaw's head dizzy, but the strong desire to survive would not allow him to do such a stupid thing, driving the last inflated climbing nail under his body and fastening the clasp to it.

Looking at the seemingly distant distance above, the outlaw suddenly felt a sense of powerlessness, and the fatigue in his mind was superimposed on the fatigue of his body, causing him to sit directly in the net and fall asleep.

"We're lucky, there's a transport plane training around here, and in an hour he'll drop a container of special equipment, and I'm not sure what's in it."

Jiang Yingxue put down the phone, her words were flat, and she couldn't tell if she was really lucky.

"It's fine.

Let's rest for an hour, we haven't slept all night, and our subsequent expedition will only be more difficult. ”

The outlaws who crawled out of the tunnel were desperately resting, but they couldn't sleep long, and they would wake up suddenly in half an hour at most.

The outlaws in the tunnels climbed back to the surface, and the lakeside camp grew more popular, and an hour later, a column of smoke rose from a colorful landmark, and a box of cargo was dropped by a passing transport plane.

The huge triple parachute slowly landed, and the impatient outlaws who had been waiting for a long time swarmed up and cut the ropes at will, eager to see what was inside.

The special preparations inside can be described as varied, there are not too many ropes, and it seems that it is only a drop in the bucket, and there is a high probability that it will not be able to reach the bottom of the tunnel.

"This kind of help is already the limit, whether we can reach the bottom or not, it seems that it still depends on our luck."

Jiang Yingxue looked at the rope in front of her, which did not account for too much, and commented with a slight frown, obviously very dissatisfied with the air support that cost a lot this time.

"It's okay, it's the so-called unintentional willow, this has the equipment we need most."

Bai Ning pointed to a few of the parachutes and said slowly, such a judgment made Jiang Yingxue's eyes light up, but in an instant, he was very worried about such a crazy plan.

Jumping from the mouth of the tunnel of one or two thousand meters, although the diameter of the tunnel is more than ten meters, but the diameter of the parachute is also more than 5 meters, and it is a parachute jump with many people.

"Do you really have to take such a risk?"

Jiang Yingxue confirmed it repeatedly, as if she was making some kind of determination.

"We don't have much time, so you just stay outside and do the transit logistics.

If possible, install an electric stretching rig at the end of the tunnel mouth to help with subsequent expeditions. ”

Bai Ning stated his point of view with a smile for the first time, although his tone was relaxed, it was obvious that it was not a discussion, but an established arrangement and instructions.

"It's fine.

My body no longer supports me to climb thousands of meters of cliffs, and perhaps not holding back is the greatest help for you. ”

Jiang Yingxue did not object, and responded lightly, as if it was the most ordinary plan to discuss.

In the early exploration, the number of people is meaningless, not to mention that no one knows what awaits them at the bottom of the tunnel.

With the entire lake that was swallowed by the tunnel before, millions of square meters of water went down like this, and no one would refute even if it was asserted that there was an underground river at the bottom of the tunnel.

In the face of this huge uncertainty, not to mention Ivan, who is afraid of death, no matter how much money is given, no one among ordinary outlaws is willing to follow.

The final result was very simple, only Ah Long was willing to go down with Bai Ning.

The early expedition team of the two is neither more nor less, but it always gives people a feeling of being sluggish and cold.

In Ivan's eyes, this is a gamble that belongs only to a madman, who will either make a profit or die on the spot.

He Ivan still wants to live a long life and live behind the strong, this is the way to live forever.
