After more than half an hour of grinding, I finally arrived near the boulder before.

The gas cylinder was obviously not on top of the boulder, and it had fallen under the boulder if it had been run in too much haste, but I didn't know where it was.

After looking around the boulder for half a circle, through a piece of light deliberately emitted between his fingers, Bai Ning finally found the oxygen cylinder.

I was just about to go up and take it, but suddenly I found that there seemed to be a special insect resting on the oxygen cylinder.

This particular insect is like a hybrid of a gas beetle and a firefly, and there is no trace of its wings, and it is not known if it can be folded and put away freely.

The fact that this kind of thing can explode means that there must be a sac cavity in its abdominal cavity for storing strong secretions, and even if Bai Ning takes advantage of it to shoot it to death, it is likely that a violent explosion will occur.

Not to mention how to control the intensity of the slap and ensure that there is no sound, the subsequent explosion of insects is enough for Bai Ning here to be buried.

Now if you want to drive it away, you can only outwit it.

After thinking about it, Bai Ning first turned off the strong flashlight, then took out the flippers pinned to his waist and fanned them a few times in the direction where the special insect was.

It is a very complex technical task to ensure the blocking of the light source and to control the intensity of the fan on the other.

Fortunately, under the stimulation of the breeze, the folded wings of the special insect seem to unfold subconsciously, and it feels like it is about to fly away with the wind.

Seeing this situation, Bai Ning didn't dare to stop, and continued to increase the intensity of the fan, and with the complete flapping of its wings, this special insect finally flew away.

Hurriedly enlarged the gap between his fingers, inspected the gas cylinder as much as possible, and found that there were no other special insects resting on it, Bai Ning hurriedly carried the gas cylinder in the dark.

After working around nervously, for fear of making a little noise, Bai Ning, who was sweating profusely out of thin air, finally put the gas cylinder on his back.

Carrying a weight of twenty or thirty pounds again, coupled with long-term high-intensity exercise, and the thinning of the air here, Bai Ning can stand here, which can already be regarded as a miracle.

There is still a distance of a few hundred meters to completely leave here, and Bai Ning, who is moving forward in the dark by the gourd painting again, although the movements under his feet are more sluggish, but he has re-explored this distance before, which also makes the current journey a lot easier.

Without making a sound, Bai Ning returned to the previous tunnel as fast as he could.

Maybe it's the sluggishness of fatigue and low oxygen to Bai Ning's body, or maybe a new special insect occasionally stops on Bai Ning's path.

When there were still more than a hundred meters away from the tunnel, a sudden crisp sound exploded at Bai Ning's foothold.

There was a violent burning sensation from underneath the shoe, which was caused by various highly corrosive organic compounds burning the rubber layer of the shoe.

At this time, he couldn't take care of it too much, Bai Ning suddenly bent down and took off the diving shoes that had been hit.

Both sides were changing because of this abnormal sound, and through Bai Ning's subsequent huge movements, the steel cylinder hit the stones on the side and made a loud noise, which immediately alarmed all the flying special insects.

Almost instantly, the entire underground cavity was once again full of stars, and a reconverging fireball meteor charged towards Bai Ning's side.

I had already expected this in my heart, opened the air supply valve and inhaled a breath of oxygen, Bai Ning turned on the speed of the 100-meter race and rushed towards the previous tunnel.

If there was a flying insect that couldn't be avoided, Bai Ning would use light or flippers to divide and shoot it away, and it was already at the edge of the underground cavity, and finally rushed out without danger along the way.

When entering the tunnel, Bai Ning turned his head to take a look, and found that those special insects seemed to only stay in this underground cavity, and most of the flying insects had already turned back after half of them.

This attribute allowed Bai Ning to avoid the risk of being chased by flying insects, but he still couldn't figure it out, where did the bearded captain who came in earlier than him go?

Will it continue to hide here and not cause it, or will it have already left here through other tunnels?

If it is the latter, then in this huge underground cavity community, if you want to meet again, you may only be based on the final location where Liu Cheng is located.

The prerequisite for this solution is that the tunnels that Bai Ning and Captain Bearded have taken can finally reach the main chamber here.

The special insects flying in this chamber are like a moat blocking the entrance of each tunnel, making it impossible to make a choice calmly.

All the choices made at the moment are like a big gamble based on their own fortunes.

If it is done, it will be done, and if it is not, it will be left here completely.

There was no time to worry about these things, Bai Ning quickly came to the vicinity of the pool, first cleaned the diving shoes that had been burned and contaminated before, and when everything was ready, Bai Ning slowly dived into the undercurrent of the pool water.

When he entered the core area of the pool, the imaginary undercurrent resistance was not so strong, and a slowly downward tunnel mouth appeared in front of Bai Ning.

Slowly moving against the wall of the cave, a short time later, an upward branch appeared in the tunnel.

If expected, this should be a tunnel to other underground cavities.

Without hesitation, Bai Ning emerged along the upward tunnel.

As soon as it surfaced, a stale air mixed with a special smell made the nasal cavities hurt.

A glance with a flashlight reveals rotting seafood stuck in the rubble pile on the shore from far or near, which seems to prove once again the problem of the food source of those special insects.

Slowly stepping out of the water, the flashlight searched around, the cavity seemed smaller than the previous one, and the only good news was that there was a tunnel going down.

Continuing along this tunnel, it was a descending passage of several hundred meters, and when the cramped environment in front of me was empty, an unbelievably large underground cavity finally appeared.

In terms of the size of the space, it is very likely that this is the location of the legendary Dragon's Lair.

Such a huge space, it is impossible to distinguish between the southeast and the northwest, and there is no distance or proximity, Bai Ning just inspects this place at will according to his instincts.

Coming to a raised boulder, Bai Ning wanted to look into the distance, but the illumination range of the strong flashlight was an unsolvable defect after all.

The empty and lonely space, I don't know that the two people who came here one after another are carrying out their mission there at this time.

Suddenly, Bai Ning suddenly saw a pillar of light swaying a few times in the extreme distance, like the traces of the previous bearded captain's presence in it.

Turning off the bright flashlight, Bai Ning continued to look in that direction a few times, only to find a pitch-black and empty void left.

Did the other party also notice the light on this side?

With a horizontal feeling in his heart, Bai Ning directly approached over there in the dark.

A few minutes later, as if sensing something, or because of Liu Cheng's affairs, the bearded captain had not been able to speed up, and the pillar of light appeared in the same direction again.

His heart was shocked, and Bai Ning accelerated towards the direction where the pillar of light was.

However, continuing to climb over a few boulders, Bai Ning found that the pillar of light seemed to be motionless, like a pillar of light bait used to attract Bai Ning.

Is the bearded captain preparing to ambush him, or has he abandoned a flashlight and wants to use it to slow down Bai Ning's pursuit?

In any case, the position of the pillar of light is also part of its trajectory, and getting closer to it faster also has certain benefits for subsequent tracking.

Maintaining a more cautious state, Bai Ning slowly moved closer to the pillar of light.

It was still about a few dozen meters away, and Bai Ning suddenly smelled a faint fishy smell.

Compared to the previous fishy smell, this fishy smell is like the rotting smell of some terrestrial animals.

The alarm bell rang in his heart, and regardless of whether he was exposed or not, Bai Ning suddenly turned on the strong flashlight and shone it over.

The pillar of light in front of him seemed to be stimulated, and it moved rapidly and violently, and the direction was exactly where Bai Ning was.

It's a ray trap!

The creature that exists here is a beast that relies on light to trap other animals!

It's hard to imagine that the average cave creature will basically lose its eyes due to a long-term lack of light.

Even in the deep sea, there are anglerfish that use light to trap other fish, but the diversity of the deep-sea ecosystem is far from being comparable to that of cave ecology.

Moreover, in this huge underground cavity that is almost dead, the underlying energy species are limited, and the existence of some small carnivorous insects is still possible, and there are some large carnivores, which is a bit abrupt!

Although he felt incredible about this in his heart, the danger that was coming to him was imminent, and Bai Ning couldn't sit still, so he hid directly behind a nearby rock, and then left the bright flashlight in place as a bait.

More than a dozen catties of gas cylinders have now become a deadly weapon in Bai Ning's hands, and he will inevitably fight for his life in a dangerous place, as long as the fierce carnivore that appears is not as huge as a lion, then Bai Ning's current trapping is effective.

The pillar of light in the distance was getting closer and closer, and the faint fishy smell was even stronger, and just when the two pillars of light completely coincided, Bai Ning jumped out and slammed the oxygen cylinder into the range of the pillar of light.

There was a muffled sound of "bang", and the front end of the cylinder really hit a soft thing, and the other party didn't even snort, and seemed to die like this.

Picking up the bright flashlight on the ground and taking a look, it was a baby fish shaped thing with a flashlight strapped to its head.

The baby fish has obviously been given a special powder, and such a masterpiece is the bearded captain's trick used to make noise.

After such a long delay, the bearded captain may have run farther away in the dark.

Flashlight flashlights to the original location, and found that there was indeed a blackout Stonehenge to help him escape.

Search along this stone formation, and every few steps you will come across some small traps.
