But after applying a little force, the speargun was light and powerless. When he pulled it out, he found that it was just an empty gun.

At this juncture, are you still doing such meaningless things? Isn't it a little too confusing to prioritize?

If you lose the rhythm of tracking Liu Cheng, you may never find that underwater passage with hidden properties.

As soon as this idea came up, Bai Ning was shocked again.

The only purpose of meaninglessly throwing rare self-defense weapons was to make Bai Ning fearful of this sand barrier.

As a result, Bai Ning's subsequent exploration process will be slowed down, and the opportunity to finally enter the undersea tunnel will be lost.

Obviously, there is indeed some kind of opening restriction on this undersea tunnel.

The current sand and dust barrier on the seabed may not necessarily come from Liu Cheng's rummaging, but probably from the bearded captain's old suspicion formation.

It is conceivable that the bearded captain must be guarding an established 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 opens the entrance to the undersea tunnel through subsequent operations, it will not be known how long it will take.

Furthermore, now that such a huge murder has occurred on this ship, the bearded captain only needs to take Bai Ning to the police if he wants to delay it.

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

With this precious time, it is enough for the bearded captain to empty out the underwater dragon's lair.

The opportunity within reach was about to be completely lost. Bai Ning didn't care whether the bearded captain had any backup plans, he just held the harpoon and dived into the sand barrier.

After entering, my line of sight was severely blocked, and I couldn't tell up, down, left, and right at all. I could only decide my direction of travel based on a given sense of direction.

He tried waving the harpoon in his hand, but nothing appeared near Bai Ning.

This seems very strange.

Since there was a sand barrier, how did the bearded captain determine his location?

The second raid came again, and as a familiar sense of crisis suddenly approached, a harpoon stirred up fast water and rushed toward Bai Ning.

Since Bai Ning's direction had changed, the harpoon was shot from Bai Ning's back. He had no time to dodge and only felt a pain in his back. The tip of the harpoon had already pierced Bai Ning's diving suit.

He quickly checked with his hands and found that there was no harpoon left on Bai Ning's body. It seemed that it was stuck on the cylinder.

The cylinder is of solid quality and cannot be easily penetrated by a harpoon. This "bulletproof vest" can be regarded as a great contribution.

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

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

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

Once there is still a long snorkeling water body in the second half of the undersea tunnel, even if Bai Ning takes the risk and rushes in, he may suffocate in the subsequent water body.

The decision between life and death was at this moment. The ruthless Bai Ning suddenly rushed in the direction from which the harpoon had just flown. He vaguely seemed to spot a figure squatting not far away.

Perhaps the disturbance of the water flow frightened him. The next moment, the black shadow quickly disappeared.

Without any hesitation, he put more force on his legs and dived away at a faster speed.

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

Judging from the current situation, this seems to be the remains of an undersea ruins. The stone slab buried in the sea sand is densely cracked. It is obvious that it was violently destroyed by something.

Can Liu Cheng erupt with such terrifying power under the sea?

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

There was no response from the crowd. It seemed that the black shadow from before did not ambush Bai Ning near the entrance of the cave.

Bai Ning quickly put his head into the hole, barely stopping, and then retracted his head.

As if flying out against Bai Ning's scalp, the third harpoon suddenly flew out of the hole. It seemed that although the black shadow was not at the hole, it was definitely not far from the hole.

It takes time to reload the underwater spear gun, but Bai Ning didn't stop, he drew the gun and got into the hole.

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

While feeling shocked, Bai Ning exerted all his strength, trying to regain his balance as much as possible in this turbulent flow.

But before it stabilized, it crashed head-on into the rocky ground on the seabed. Looking closely, I found that the underground cavity was larger than expected.

The overall description is like an undersea tomb.

After scanning around with a strong flashlight, I found some coffin-like stone objects, and countless rotten funerary objects suspended in the tomb.

Vaguely, it seems that a black figure can be seen leaving in an unknown direction.

After thinking about it all, the black shadow just now was hiding at the bottom of the submarine tomb, thinking of ambushing him in the end.

Without time to pay attention to the details of this large underwater tomb, Bai Ning continued to swim in the direction of the black shadow. When he reached the end, he found a stone door that was slowly closing.

At this time, the stone door was still one body wide. If Bai Ning delayed a little, or was confused by the pattern in the tomb, he might temporarily lose the opportunity to enter the subsequent tomb passage.

After looking at the remaining half of the gas storage, Bai Ning turned the air supply valve smaller. Even if the breathing pressure was greater, it would still be much better than eventually suffocating to death.

Using his feet on the stone wall next to him, Bai Ning held the harpoon and dived into the subsequent tomb passage. At this time, Bai Ning was like a swift human harpoon. As long as the black shadow from before dared to stop him, he would surely Take a big one.

When Bai Ning entered the subsequent tomb passage, he didn't see the previous dark shadow in the light pillar. It was most likely because he ran out of harpoons and could only choose to hibernate temporarily.

Now, only three people have entered the entire dragon lair, and the members of the Night Demon Society who have disappeared in the chaos have no idea where they are.

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

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

If the members of the Night Demon Society jump over the wall and start demolishing the underwater tomb at the entrance of the Dragon Cave, perhaps the entire internal structure of the Dragon Cave will undergo subversive changes due to the intrusion of seawater.

Now that Bai Ning's oxygen reserves are stretched thin, once the key passage in the dragon's lair is blocked by sea water, Bai Ning may really be trapped and die inside.

It was still the unfavorable situation of a wolf in front and a tiger in the back. Already in this absolute crisis, Bai Ning also knew that he had no way out.

Light shines through the turbid water, in which Bai Ning swims as smoothly as possible to minimize the rate of oxygen consumption.

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

Slowly arriving at the shallow water area, Bai Ning slowly stood up from the water. He fired his bright flashlight in all directions and found no one ambushing him.

Above the water is a very cramped cave, with 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 people before had just left not long ago.

The bearded captain didn't even take off his diving gear and just carried the weight forward?

Considering the importance of diving equipment in this deep seabed cavity, it is normal for him to do this.

Bai Ning took off his flippers and hung them around his waist, dropped the lead pendant, and carried twenty or thirty kilograms of equipment on his back to continue tracking step by step.

The air in the underground cavity was very turbid and the oxygen content was very low. Carrying dozens of kilograms of equipment, Bai Ning started to pant after just a few steps.

This phenomenon means that this underground cavity is a place of death. It is really hard to imagine that this could be a dragon's lair.

I don't know how far the descending tunnel extends downwards. In a daze, I feel a sense of fear of going deep into the netherworld cave.

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

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

There was no other way. Bai Ning could only take a few breaths of oxygen from time to time before he could reluctantly move on.

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

Within the scope of the light beam, there are jagged rocks and patches of reflection on the ground, which seems to indicate that there are some small ponds here.

In such a huge cavity, with stones of various sizes stacked on top of each other, it seems extremely difficult to find traces of two people in it.

In addition, this huge underground cavity is also a good place to hide and ambush. If you are not careful, you may be killed by the bearded captain here.

The light beam looked around on both sides of the cave entrance, but did not find any obvious footprints. He continued to look and found a huge raised rock in front of him. Bai Ning unloaded his equipment and climbed up in three or two steps.

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