But with a little force, the speargun was light and powerless, and when I pulled it out, I found that it was just an empty gun.

At this juncture, is it a bit too difficult to prioritize such meaningless stupid things?

If you lose the rhythm of tracking Liu Cheng, it is likely that you will never find the undersea passage with hidden attributes again.

As soon as this thought came to mind, Bai Ning's heart was shocked again.

The only purpose of throwing a rare self-defense weapon meaninglessly was to make Bai Ning jealous of this sand and dust barrier.

In this way, Bai Ning's follow-up exploration process will be slowed down, and he will lose the opportunity to enter the undersea tunnel at the end.

It is clear that there is some kind of ban on opening this undersea tunnel.

The current seabed sand and dust barrier does not necessarily come from Liu Cheng's rummaging, but probably from the bearded captain's suspicious array.

It is conceivable that the bearded captain must have been guarding a given entrance at this time, quietly waiting for the entrance to close.

In this way, Bai Ning completely lost the opportunity to track.

Even if Bai Ning forcibly opened the entrance to the undersea tunnel through subsequent operations, it was not known how long it would be later.

Moreover, now that such a huge murder has occurred on this sea ship, the bearded captain only needs to stab Bai Ning to the police if he wants to delay Bai Ning's time.

As a result, Bai Ning is bound by the legal process and may lose the opportunity to enter the dragon's lair in the short term.

With the help of this precious time, it was completely enough for the bearded captain to hollow out the dragon's lair under the sea.

The opportunity that was within reach was about to be completely lost, and Bai Ning didn't care whether the bearded captain had a back hand or not, he directly held the harpoon and plunged into the sand and dust barrier.

After entering, the line of sight is seriously blocked, and it is impossible to distinguish between up and down, left and right, and can only decide the direction of travel according to a predetermined sense of direction.

Trying to wave the harpoon in his hand, nothing appeared near Bai Ning.

This seems strange.

Since there is a barrier of sand and dust, how does the bearded captain determine his location?

The second raid came again, and as a familiar sense of crisis suddenly approached, a harpoon stirred up a swift stream of water and galloped towards Bai Ning.

Since Bai Ning's direction had changed, the harpoon was shot from Bai Ning's back, and it was too late to dodge, only to feel a pain in the back, and the tip of the harpoon had been pierced on Bai Ning's diving suit.

Quickly confirmed with his hand that there was no harpoon left on Bai Ning's body, and it seemed that it should be stuck on the gas cylinder.

The quality of the gas cylinder is sturdy, and it is not at all easy for a harpoon to penetrate, and this "body armor" can be regarded as a great achievement.

Just breathing a sigh of relief, Bai Ning suddenly felt that the oxygen pressure in the air valve seemed to be much smaller.

There is no doubt that although the harpoon just now did not pierce Bai Ning, it pierced the oxygen pipe, so that a large amount of oxygen was diverted out by Bai.

As a result, Bai Ning's effective time for diving was suddenly shortened.

Once there is still a long body of water in the second half of the undersea tunnel, then even if Bai Ning risks rushing into it now, he may suffocate in this subsequent body of water.

The choice of life and death was at this moment, and Bai Ning, who was ruthless in his heart, rushed suddenly in the direction where the harpoon flew just now, and vaguely, it seemed that he found a figure squatting not far away.

Perhaps it was the disturbance of the water that frightened him, and in the next moment, the dark shadow quickly disappeared.

There was almost no hesitation, and the legs were pushed harder, and the snorkel was faster and faster.

In a flash, Bai Ning finally arrived at an area where the sea sand was relatively thin, and a hole in the stone slab loomed in front of Bai Ning.

As it stands, it seems that this is indeed the wreckage of an undersea ruin, cracked in the slabs buried in the sand, apparently violently destroyed by something.

Could Liu Cheng be able to burst out with such terrifying power at the bottom of the sea?

Continuing to swim towards the entrance of the cave, Bai Ning also kept an eye on it, and as soon as he arrived, Bai Ning pierced the harpoon in his hand into the hole.

Empty and unresponsive, it seems that the black shadow before did not ambush Bai Ning near the entrance of the cave.

Quickly sticking his head into the range of the hole, barely stopping, Bai Ning retracted his head again.

As if it flew out of Bai Ning's scalp, the third harpoon flew out of the cave mouth, and it seemed that although the black shadow was not at the mouth of the cave, it must be not far from the mouth of the cave.

It takes time for the submarine speargun to be reloaded, Bai Ning didn't stop, and the gun went into the hole.

But as soon as he entered the cave, he was surrounded by a turbulent current, as if he was pushing Bai Ning to deviate in other directions.

While his heart was shocked, Bai Ning exerted all his strength, trying to restore his balance in this turbulence as much as possible.

But before it could stabilize, he crashed head-on into the rocky ground at the bottom of the sea, and when he looked closely, he found that the area of the underground cavity was even larger than expected.

The overall description is like an undersea tomb.

The flashlight swept around, and some coffin-like stone objects were found in it, and countless rotting burial goods were suspended in the tomb.

Faintly, it seems that a dark figure can be seen leaving in an unknown direction.

Thinking about it as a whole, the black shadow just now was ambushed at the bottom of the submarine tomb, thinking about ambushing him at the end.

didn't have time to take care of the details of this undersea tomb, Bai Ning continued to swim in the direction where the black shadow was, and when he came to the end, he found a stone door that was slowly closing.

At this time, the stone gate still has the width of a body, if Bai Ning delays a little, or is confused by the pattern in the tomb, he may have to temporarily lose the opportunity to enter the subsequent tomb.

Looking at the remaining half of the gas storage capacity, Bai Ning screwed the air supply valve a little smaller, even if the breathing pressure was greater, it was much better than suffocating to death in the end.

With his feet on the stone wall beside him, Bai Ning held the harpoon and slammed into the follow-up tomb, Bai Ning at this time was like a swift human harpoon, as long as the previous black shadow dared to stop it, he would definitely eat a big one.

When Bai Ning entered the follow-up tomb, he did not see the previous black shadow in the pillar of light, most likely because the harpoon was exhausted, so he could only choose to lie dormant temporarily.

Now, only three people have entered the entire dragon's lair, and the Daredevil members who have disappeared in the chaos have no idea where they are.

The situation in the field seems simple, but no one knows what the members of the Daredevil will do in order to enter the dragon's lair.

So, the situation here is actually more dangerous than expected.

If the personnel of the Daredevil Society jumped over the wall and directly began to forcibly demolish the underwater tomb at the entrance of the Dragon's Den, perhaps the internal structure of the entire Dragon's Den would undergo subversive changes due to the inflow of seawater.

Now Bai Ning's oxygen reserves are stretched, and once the key passage in the dragon's lair is sealed by the seawater, maybe Bai Ning may really be trapped inside.

It is still an unfavorable situation of the former wolf and the tiger, and he is already in this absolute crisis, and Bai Ning also knows that he has no way out.

The light penetrates the murky seawater, in which Bai Ning swims as smoothly as possible to minimize the rate of oxygen consumption.

When there was still 20% of the gas storage capacity left in the oxygen cylinder, he finally saw the fault of the pillar of light, and a bright wave of light floated above Bai Ning's head, indicating that he had come to the underground cavity.

Slowly coming to the shallow water area, Bai Ning slowly stood up from the water, and the bright flashlight swept around, but he didn't find anyone ambushing on the side.

Above the water is a cramped cavern, a deep tunnel leading down to an unknown area.

The water stains on the ground were messy, and different footprints overlapped each other, indicating that the two had just left.

Did the bearded captain not even take off his diving equipment and move forward directly with his load?

Considering the importance of diving equipment in this deep underwater cavity, it was not uncommon for him to behave in this way.

Taking off his flippers and hanging them on his waist, he threw down the plumb pendant, and Bai Ning also carried twenty or thirty pounds of equipment on his back and continued to track step by step.

The air in the underground cavity was very turbid, the oxygen content was very low, and he was carrying dozens of catties of equipment, and Bai Ning had already begun to pant after taking a few steps.

This phenomenon means that this underground cavity is a dead place, and it is really hard to imagine that this could be a dragon's den.

I don't know how far the downward tunnel has stretched, and in a trance, I feel a sense of trepidation going deep into the Netherworld Cave.

When the well was first drilled, it showed that the underground cavity was three or four hundred meters below sea level, but judging from the current travel distance, Bai Ning's current depth should be much more than that.

Due to the relationship of carbon dioxide deposition, the further down you go, the higher the carbon dioxide content in the air, and the feeling of palpitations and dizziness will follow.

There was no way, Bai Ning could only occasionally breathe a few breaths of oxygen before he could reluctantly continue to move forward.

After walking forward for an unknown amount of time, the irradiation range of the pillar of light suddenly widened, and a suddenly open underground cavity suddenly appeared in front of Bai Ning.

Within the range of the pillar of light, the strange rocks are craggy, and the reflection on the ground seems to indicate that there are some small ponds here.

With such a huge cavity, with stones of all sizes stacked on top of each other, it seemed extremely difficult to find the traces of two people in it.

In addition, in this huge underground cavity, it is also a good place to hide and ambush, if you are not careful, it is very likely that you will be killed here by the bearded captain.

The pillar of light looked around on both sides of the cave entrance, and found no obvious footprints, continued to look, and found that there was a huge raised rock in front of him, Bai Ning took off his equipment and climbed it in three or two steps.

Turning off the flashlight, Bai waited quietly on the boulder, he wanted to see how the bearded captain could cross this underground cavity without a light source.
