Coming to the entrance of the cave again, Shao Xinghai and the boss glanced at each other.

This time they were on guard, and both of them had two heavy weapons in their hands.

As long as one thing happens, it will be a fatal blow in an instant.

They will not be soft-hearted, even if they find any bewitching beauties in the cave, they will bombard them in an instant.

It can be said that no matter what kind of thing appears in the cave, as long as it is alive, they will do whatever it takes to strangle it.

As the two went deeper, the light became darker and darker, but fortunately, they both bought night vision goggles, so their vision was not affected much.

Squeak squeak......

A rat snorted on the wall looking for food, making a small sound.

Shao Xinghai and the boss raised their hands and shot without any hesitation.

With a silencer, the sound of the bullet did not sound, but the hapless mouse could no longer get up.

The tense hearts relaxed because of the mouse, and the two of them looked at each other and smiled bitterly.

They were too nervous to shoot at the first opportunity, and both of them did it at the same time.

It was already thousands of meters away from the entrance of the cave, and the two of them were faced with a choice again.

The five entrances appeared in front of them again. How to choose?

"Xinghai, which one to take?" The boss asked in a light (one) (book) reading (novel) ybdu.

Shao Xinghai was also difficult to make up his mind.

The most difficult situation has arisen.

None of them knew which one was the entrance directly to the Snake Emperor. What if the other four junctions lead to other places?

These fears are not unfounded.

They didn't know how long this dark entrance was, and how dangerous it was.

"No matter, start on the left! If you don't find anything after a kilometer, turn around immediately. Shao Xinghai gritted his teeth and said.

"Good!" The boss didn't have too good ideas either, and he clung to it.

In order to hurry up, after the two made a decision, they stepped into the first passage with heavy steps.

It's still so dark, I can't see my fingers. At a distance of less than a hundred meters, the sound of water droplets began to appear on the walls, and the deeper you go, the more intense the humid air became.

Thump...... Thump...... Thump......

"Boss, did you hear anything?" The two continued to move forward for about a few hundred meters, and Shao Xinghai suddenly stopped and listened quietly.

The boss stepped on the deep ditch, and there was the sound of dense dripping of water droplets everywhere, and he suddenly shook his head and said, "I didn't hear it." ”

Shao Xinghai felt strange, he had heard a plopping sound that was thicker than water droplets just now, but when it was quiet, he couldn't hear it.

Although the voice disappeared, the inner uneasiness grew stronger.

"Boss, be careful, I always feel a sense of foreboding." Shao Xinghai said.

"Xinghai, should we consider evacuating?" The boss said what he was thinking, "The Snake Emperor shouldn't choose to hibernate in this ditch, right?" ”

Shao Xinghai thought about it for a while, and felt that what the boss said made sense, and now it was not far from a position of a thousand meters deep, and if he went any further, he didn't know what would happen.

Besides, the sense of foreboding was getting closer and closer, as if a terrible creature would suddenly appear under their feet at any moment to surprise them.

As the two were about to return the same way, they were startled by an unusually loud "plop" sound.

Da Da Da ......

A shuttle of bullets was all thrown into the water by the boss in an instant.

"Run!" Shao Xinghai immediately grabbed the boss's arm and stepped back.

However, the plopping sound became more and more intense.

When he got closer, Shao Xinghai finally knew the source of the sound.

Raising his head, with nervousness, Shao Xinghai suddenly looked above his head.

Disgusting orbs fell from the walls overhead and into the water.

After hundreds of thick tumors fell into the water, they all spread out as if they had escaped from a trap, turning into slippery unknown creatures.

They chased away with great speed in the direction of Shao Xinghai.

One by one, the monsters opened their bloody mouths and bit down on their thighs. Fortunately, Shao Xinghai's spiritual power unfolded at this moment, so he could discover their movements and immediately shoot them.

"Boss, seven monsters are swimming towards you at nine o'clock and twelve o'clock!" Shao Xinghai shot while telling the boss about the monster's movements.

The boss nodded, and immediately opened fire.

The two of them immediately fought and kept retreating.

Five minutes later......

The two of them finally got out of the ditch and went to the land, and they were sweating all over their bodies and watched the disgusting monsters hovering on the edge of the ditch but did not dare to go up to the land to attack, and finally breathed a sigh of relief.

"What the hell is this TM?" The boss wiped the sweat from his forehead and scolded.

Shao Xinghai couldn't see what these creatures that were glued to the roof of the cave and appeared when they met the water. But no matter what kind of creature it was, Shao Xinghai had no interest in it anymore.

"Boss, let's go!" Shao Xinghai and the boss rested for less than half a minute, and immediately left the first passage.

Actions have proved that the first path is wrong. Now, they have to choose the right one of the four channels.

With a quarter chance, they are one step closer to the Snake Emperor.

"Boss, you choose this time." Shao Xinghai gave the choice to the boss, hoping that the boss's luck would be better than his own.

The boss was not polite or twisted, and directly chose the second one.

He originally wanted to choose the third one, but the reason why he had such an idea was because he felt that the Snake Emperor was actually the emperor of Snake Island, and the place where he lived must be in the middle, and the passages on both sides of him were the protectors who guarded them.

This bizarre idea is not without reason, and it has been proven that this possibility has accounted for more than 70 percent throughout the ages.

And he gave up on the idea because he liked to arrange the choices in order.

The second channel is different from the first, it is somewhat dry, and even the deeper you go into the air, it becomes thinner.

800 meters......

"Xinghai, I can't breathe anymore." The boss gasped and said with difficulty.

Shao Xinghai also had a flushed face and a dry mouth. He looked at the boss who was about to collapse, and said, "Go, get out of here!" ”

The reason why it was so simple was because Shao Xinghai thought that even if this road was really the only way to find the Snake Emperor, it would definitely not be possible to go down. Because, the air is getting thinner and thinner.

Without the support of oxygen, even if they were the Snake Emperor, they would suffocate to death, let alone fight against the Snake Emperor.

Although the two were ready to die in battle, they didn't want to die like this.

However, what they didn't expect was that when they retreated to a distance of about five hundred meters, they found that the exit was blocked.

A rock directly blocked their escape route.

The two tried to blast it open with their weapons, but they didn't expect that the rock was as hard as iron, and the thickness was incomparably thick, and it couldn't be broken at all.

"Find the switch!" Shao Xinghai said hopefully.

At a distance of 500 meters, the air and oxygen will come more than at 800 meters, which is enough for them to hold on for a while and a half.

While fumbling for the switch on the wall in a panic, Shao Xinghai also silently prayed in his heart not to encounter any more dangerous things.

Only, the good spirits do not the bad spirits. As soon as he finished praying, he saw a figure from the depths of the passage. Then came the second course, the third course......

Within the line of sight, Shao Xinghai saw at least five figures staggering towards them as if they had been lost.

As they approached, Shao Xinghai and the boss saw this figure, and their heads became numb.

The figures all had green faces, covered with scales like snake scales, glowing with a cold green glow.

The eyes are the eyes of a snake, with snake-like skin, but with a human-like body.

"Snake Man!" Shao Xinghai said with a look of despair in his eyes.

Under the investigation of spiritual power, Shao Xinghai learned the information of these figures.

Snake Man: A level 5 warrior. With powerful and infinite attacks and super defense, it generally survives in a thin environment, and when it encounters invaders, it will be entangled endlessly.

"Xinghai, what should I do?" The boss was also anxious.

If they really fought the snake people in the clearing, they wouldn't be so alarmed, but now, the most critical thing for them is not to face the snake people, but the oxygen that should be.

Without the support of oxygen, even if they defeat the snake people, they will suffocate to death due to lack of oxygen.

"Boss, you continue to look for switches, and I'll deal with these snake people." Shao Xinghai made a decision immediately.

The more critical the moment, the calmer Shao Xinghai's mind became, analyzing all kinds of possibilities.

"Xinghai ......" Before the boss finished speaking, Shao Xinghai interrupted: "We don't have time, so let's decide!" ”

Controlling his heart to breathe when needed, Shao Xinghai's body rushed into the snake crowd like lightning.

Bang!

Boom!

The Sand Eagle-Canglong and the Shura Blade attacked the same snake man, but they only left a pale trail, unable to break through its defenses.

Shao Xinghai was very clever and retreated with one blow. After trying his normal attacks and not being able to do any damage to them, he finally used a thermal weapon with relatively strong lethality.

A cool black cannon gun was taken out by Shao Xinghai, this cannon gun is much larger than an ordinary pistol, weighing dozens of catties, and the ring like a screw pattern is like a gene chain around the body of the gun.

There was a net-shaped unknown gold wire in the muzzle, and when Shao Xinghai pressed the trigger, the net-shaped gold wire was like a vacuum cleaner, and it began to accumulate power, and suddenly, the muzzle became unusually fiery red. That heat can melt almost the hardest gemstones.

"Die!" Shao Xinghai let go of the trigger button, and the muzzle golden cannon fire that had been charged instantly formed a pillar of light, blasting towards the snake man who was walking in the front.

Rumble...... Bang......

Because the power was too strong, Shao Xinghai was repelled by the recoil of the artillery's bullets.

He took a few steps before stopping, and then looked ahead...... His eyes were momentarily sluggish.
