If it weren't for the fact that Zhang Fan was wearing a gas mask on his face at this time, and his eyes were not protected by goggles, he might have been stimulated by the turbid sea water and couldn't open them.

However, the only thing to be thankful for is that the headlamps issued in this maze scene are of extremely high quality, and seem to have the effect of waterproofing, even in deep water, they can still be illuminated.

It's just that the range of illumination is not very far, and it is blocked by various foam impurities in the water, and it can only illuminate a distance of one or two meters.

Just now on the elevator, Zhang Fan had carefully looked at the map, as long as he dived to the bottom of the water in one breath, and after reaching the bottom, he swam to the left side to the end, and he could see a huge nutrition tank inserted upside down in the soft silt.

The ventilation duct is located at the back of the tank, and when the time comes, you can get into it by opening the iron fence that is used to block it.

As long as he can enter the ventilation duct, Zhang Fan's task this time will be completed for the most part, and then continue to go deep into the end of the pipe, find the turbine-shaped fan and turn on the reversal switch, and it can be directly blown to the fifth-floor base station, so that the task will be completed.

Zhang Fan swam towards the bottom of the water with all his might. As we went deeper underwater, the surrounding situation became worse and worse, not only did there become more garbage and impurities, but there were even a lot of swollen and rotten corpses floating by.

The corpses were all dressed in yellowed hazmat suits, both men and women, who were apparently members of the research base during their lifetimes, and may have been attacked by terrible monsters, so they all died here quietly.

Zhang Fan glanced at these floating corpses with the help of the headlight, and was extremely surprised to find that all the corpses were all swollen and rotten eyes, and they looked like they were dead.

Seeing this, Zhang Fan didn't dare to look at it more, he was a little stunned in his heart, and the whole person became creepy. I don't know if it's an illusion or a real thing, he always feels that these corpses are staring at him with an extremely resentful look.

It seems that he is blaming Zhang Fan, why he came to disturb their sleep. Adjust his mentality, Zhang Fan's diving speed is much faster.

The distance between the water level and the bottom of the water is nearly forty meters, if it weren't for the fact that the gas masks in this world are advanced enough, and a small oxygen cylinder is embedded in the cheeks on both sides to provide Zhang Fan with a steady stream of oxygen, maybe he would have been unable to hold back and began to drown.

To be honest, it's all fake to dive to such a deep place and not be afraid. For diving, Zhang Fan has a kind of fear and psychological shadow from the heart.

I don't know how long it took, Zhang Fan finally desperately dived to the bottom of the water. The bottom of the water was even darker, as thick as ink, and the temperature at this time was nearly a dozen degrees lower than that on the surface of the water.

Fortunately, he was wearing a chemical protective suit, which barely played some role in protecting against the cold, otherwise, Zhang Fan would probably freeze to death.

Now is not the time to think about this, Zhang Fan turned his headlamp and looked to the left. The first priority is to find the huge nutrient jar as soon as possible.

Only when the nutrient tank is located can the location of the ventilation duct be determined. Suddenly, at a certain moment, Zhang Fan's heart moved slightly, revealing excitement, because he saw that about ten meters away on the left, there was a jar with a volume of nearly two meters, which was inserted diagonally under the water.

Zhang Fan fixed the headlamp, used his hands and feet together, showed a breaststroke shape, and swam quickly. It's just that...... The moment he swam past, the corpses he had just encountered above appeared strangely one by one.

All the corpses' eyes were still wide, a pair of swollen and rotten eyes, two lines of pitch-black blood flowed out, and then the bodies of these corpses began to swell violently, and after two seconds, their rotten and white bodies swelled into a blood-colored ball of flesh.

But their facial features and limbs are still there. The mutation did not end there, but continued to change.

The ball of flesh is formed, and gradually grows hideous and sharp white bone spurs. The bone spurs grew violently from the corpse's forehead, arms, chest, eyes, back, legs, and every inch of the body.

This situation and this scene looks like a hideous sea urchin that wants to tear everything in front of it to pieces. After all the corpses were transformed into sea urchins covered with white bone spurs, they quickly rushed towards Zhang Fan.

"Wow wow-"

"Wow-wow-" They swirled in the water, their mouths open in the shape of O, and from time to time they let out baby-like wails.

However, the bottom of the water is depressed and heavy, and it is covered by the high density of sea water, and the sound cannot be transmitted too far, otherwise Zhang Fan will be frightened when he hears it, and he will be frightened to flee ashore immediately, and find another way to go to the fifth-floor base station.

But...... Just as all the corpses and sea urchins were chasing Zhang Fan, suddenly, in the next moment, a strange scene happened.

A black figure with a cloak also arrived at this moment, directly and stiffly blocking in front of the corpse sea urchin group.

The corpse sea urchin sensed the arrival of the black figure, and did not stop moving, but turned more rapidly, with a posture of death in the way of me.

It was less than two meters before they reached the black figure. The black figure suddenly moved, but it moved its head.

It was as if he had looked at it. Looking at it, all the corpse sea urchins, the mouth that was shaped O, suddenly, thick black hair gushed out.

Not only the black hair gushed out of the mouth, but also the eyes, nostrils, ears, and all the holes in the body were frantically gushing out of black and thick hair.

Or even ...... Even the pores of sweat began to overflow. Gradually, the corpse sea urchin could no longer make a sound from its mouth.

Completely, completely devoured by black hair. At this time, the group of corpse sea urchins was exhausted by the black hair gushing out of the body, and it quickly wrapped into a large cocoon of black hair.

The cocoon formed, and the black figure slowly raised his left hand and waved to them numbly. With one move, the black cocoon shrank rapidly at a speed visible to the naked eye, and soon turned into a ball of foam and dissipated.

After doing this, the black figure swam towards Zhang Fan again. ......

"Bang dang!" Zhang Fan used both hands to pull open the iron fence at the entrance of a ventilation pipe. It's dark and dreary, with no end in sight, and I don't know what kind of danger lurks.

A look of solemnity appeared in Zhang Fan's eyes, and he was a little hesitant in his heart. He was hesitant to get in.

What if there is a monster in the pipe, and you rush into it and hit it directly? But I finally dived here to swim to the end of the ventilation duct and turn on the turbine fan, so that I could quickly reach the base station on the fifth floor.

If he gave up, Zhang Fan was unwilling. In the end, Zhang Fan clenched his fists and plunged into it.

Regardless of whether there is danger or not, you have to try to gamble. The ventilation ducts are also covered by seawater, and the internal space is only half a meter wide, and only one person can barely get in.

Zhang Fan struggled to swim forward. The more you crawl inside, the colder the temperature becomes.

At the back of the depths, it was already much colder than when I first dived to the bottom. At this time, Zhang Fan was shivering from the cold, and he couldn't stop shivering.

It's cold, it's so cold, it's like standing naked in the winter snow, trying to freeze people to death.

However, his luck was not too bad, and he swam forward for nearly a few tens of meters before coming to the end, and in the process, he did not encounter any danger.

Here, at the end of the pipeline is a huge power chamber on its own. Although the power compartment is still covered with seawater, there is no darkness at all, but the lights are dazzling, and the temperature has risen significantly.

A giant fan with a body size of about ten meters stands here. The silvery-white pipes are tightly connected to the fan, as if to provide it with energy power.

Despite this, the fan stopped for some reason. Zhang Fan climbed out of the pipe and swam in the direction of the fan.

A few minutes later, he arrived at the machine that operated the fan. The machine is full of colorful buttons, and the names of many buttons are marked in English.

Zhang Fan read carefully and began to look for the reversal button. Soon, he finally found it. Almost without any hesitation, Zhang Fan rotated the button counterclockwise and returned it to 12 o'clock.

Then he pulled the huge lever with his right hand. In an instant, the fan began to spin slowly. The faster and faster it turns, the faster it becomes.

The wind speed is like a force 12 wind, and it suddenly appears. Stir the seawater inside the power compartment into a terrifying whirlpool.

The whirlpool of air mixed with terrifying power converged into a turbulent waterspout. A waterspout is formed, and in an instant, all the seawater is blown out along the ventilation ducts.

Zhang Fan was in the middle of the whirlpool of seawater, rippling with the current, and before he could react, he was also swept out together.

The huge water wave air flow quickly blew Zhang Fan out of the ventilation duct and into the water pool outside.

But the waterspout still didn't stop, it still turned. swept Zhang Fan into it and went straight towards the depths of the water.

And at the end of the water pool, there is a five-story base station. The black figure stood stiffly at the bottom of the water, looked slightly sideways in the direction where Zhang Fan was swept away, tilted his head, and slowly followed.

It's just that the speed of its chase, amazingly fast, can't be imagined. With one step, he crossed a distance of nearly six or seven hundred meters from the bottom of the water.

Maybe it won't be long before it can catch up with Zhang Fan soon. ....... When Zhang Fan opened his eyes, he saw that he had appeared in a bright and wide huge base.

On the high wall of the base, a figure made of yellow paint is painted. Obviously, this is the fifth-story base station.

There is no seawater at the base station on the fifth floor, it is clean, and the air is even a little fresh. Seeing this, Zhang Fan's expression showed joy, took off the gas mask, and greedily took a puff of oxygen from the base station.

After taking this breath of oxygen, he quickly put on his gas mask again. He was afraid that the base station would be filled with the mysterious dust that Wei Wenshan had said.

At this moment, a loud rumbling sound resounded in front of him. Hearing this, Zhang Fan hurriedly looked up and saw a huge lizard monster with no skin and drenched in blood, falling from the ceiling of the base station and slamming heavily to the ground.

This lizard monster stretched ten meters long, with a large bloody mouth, flowing transparent viscous liquid, and a slender and forked tongue, spitting out of its mouth, setting off a fishy wind.

When it got up, it noticed the existence of a living person, and suddenly stared at a pair of snow-white dead fish eyes, and looked at Zhang Fan.

"Roar-" The skinless lizard monster let out a deafening roar, and in the next second, it swooped towards Zhang Fan with a high jump.

"Damn!!" Seeing this scene, Zhang Fan's face changed drastically, and he secretly said damn it, and before he had time to think about it, he raised his hand and aimed the shaped cannon at the lizard monster.

Before he could go into the water, he put the power stone back into the shaped cannon, just because he was afraid that he would encounter some danger during the dive.

Now that this monster is approaching, it just confirms Zhang Fan's worries. The trigger pulled, the imaginary sonic boom, did not appear.

Instead, a fishy seawater leaked out directly through the cracks of the energy cannon and scattered all over the ground. It seems that this shaped cannon, which is specially designed to deal with monsters, cannot be used after being soaked in seawater, and completely fails.

Seeing that the concentrating cannon was out of order, Zhang Fan's heart was beating wildly, and his forehead was instantly wet with cold sweat. Without the help of the Shaped Cannon, he would have really died now.

At this moment, the skinless lizard monster was already less than three meters away from Zhang Fan.

"Plop!" Suddenly, there was another dull crashing sound. Zhang Fan was awakened by the sound, he subconsciously glanced back quickly, and saw a figure with a cloak falling from mid-air and smashing to the ground.

Just when he was about to say something, there was a strong and indescribable sense of murderous restlessness in his heart, which exploded violently.

This is a terrible murderous restlessness from the parasinics. Generally, when encountering an irresistible life and death crisis, the parasitic spirit will uncontrollably issue a restless warning.
