The mutant tiger head fish is level 46, with less than 100,000 blood, and his horizontal eyebrows are very fierce, biting Raven's tail and refusing to let go. Pen ~ fun ~ pavilion www.biquge.info

It's just an ordinary mutation, it's not infected by the otherworldly aura, and it doesn't look vulnerable at all.

Raven's eyes turned red, and in the blink of an eye, he cut off its head with a hot ray, and the sea water turned red, and the blood of the mutated tiger head quickly spread into the sea.

A number of large orbs of experience spilled out of its corpse, and although it was vulnerable, it still contributed a lot of experience points to Raven.

After killing the mutant tiger fish, Raven began to look around again.

It's a pity that there aren't many monsters in the surrounding area, and they're quite scattered, and Raven collected them for a while, but the harvest was not large.

He hopes to be able to encounter a large number of monsters in the center of the laboratory, and according to Xingli, the reason why players avoid this place is because of the number of monsters and ferocity, and there is even a terrifying old monster, where many players have lost their lives.

After searching the outer areas of the lab, Raven still found nothing, so he decided to move towards the central area.

At this moment, a pair of blood-red eyes lit up in the darkness in the distance, and Raven saw several black shadows swimming quickly in his direction!

It's a group of mutant great white sharks! There are more than a dozen of them! Judging from their size, the level is not low, and one of them is close to 15 meters long, which is quite huge!

Those guys may have been attracted by the blood of the fish that Raven had slaughtered, and it was just right for him, and it came at the right time!

More than a dozen great white sharks slaughtered Raven with great momentum.

When he got closer, Raven found that they were all of high levels, the lowest was level 49, and the largest one was as high as level 57, with more than 600,000 HP!

The sharks quickly killed and took the lead in launching a swift attack on Raven, and more than a dozen great white sharks surrounded them at once.

Raven's tail, legs, arms, and shoulders were all bitten by the great white shark.

The rows of teeth in their mouths were like saws, biting Raven at each other, using their mature hunting skills to swing their bodies to create torque, trying to tear Raven's body apart.

Maybe with other prey, they will have a good effect. However, their current opponent is Raven!

No matter how desperately the great white sharks tore Raven's body, they couldn't shake him in the slightest!

Raven wouldn't let them attack, he suddenly raised his claws, and slapped a fierce claw at a great white shark that was biting his shoulder, and with a muffled bang, the great white shark's forehead bone was directly shattered, and the plasma burst open, instantly staining the surrounding sea water.

The eight-meter-long great white shark was directly shot to death by Raven, and even though the sea weakened Raven's strength, this level of attack was still not something that this creature could afford.

Raven's eyes lit up, and it took him just two seconds to cut another great white shark biting his left arm in half.

A bloody battle began, these high-level mutated great white sharks were completely unable to pose a threat to Raven, his energy absorption greatly weakened their attacks, and the opponents' attacks sent Raven a lot of energy.

In less than ten minutes, all the great white sharks were killed by Raven.

Even the biggest one had only been in Raven's hands for a minute.

These great white sharks have contributed a lot of experience to Raven, and he is quite satisfied. Other than that, however, they have nothing else to contribute to Raven, and they don't drop Otherworldly Breath Crystals or other materials.

There is also an otherworldly aura infection area in the middle of the sea, but that place is far from here. Of course, this does not mean that there are no sea creatures infected by the breath of the otherworld, and it may be possible that some of the infected sea creatures have moved here, but there are definitely no more of them.

After picking up all the experience orbs dropped by the great white sharks, Raven swam to the heart of the lab, where he hopes to encounter more monsters. If the monsters won't come out, he'll cook the whole place to see what it's like.

Raven swam towards the center of the lab, and suddenly, a crisp sound came from the surrounding sea.

The sound seemed to ripple through the water, quickly passing over where Raven was, and reaching into the distance.

Raven didn't understand how there could be such a sound in this abandoned place, and the voice immediately came again, ticking......

"This ...... Could it be ......" Raven finally thought of something.

Xingli hurriedly said to him at this time: "Master, this is sonar, there must be a submarine nearby!" ”

Sonar is an electronic device that uses underwater sound waves to detect, locate and communicate underwater targets, and is the most widely used and important device in underwater acoustics. Such equipment is indispensable for submarines.

Raven thought of this and had to worry. The sonar detection system is very powerful, and his body is so large that it is easy to spot.

He wasn't sure if his energy absorption would absorb the sound wave, so he immediately swam to the bottom of the ocean.

His Retreat must come into contact with the earth to be unleashed, and it cannot be used while floating in water.

Soon, Raven descended to the bottom of the ocean. However, instead of using the Escape Technique, he hid in a dark corner. Dense seaweed covered his body, and he wanted to see if the submarine could spot him.

Backbite...... There was another crunch.

Raven lay motionless among the seaweed and laboratory ruins at the bottom of the sea, staring silently in the direction from which the voice came.

After a while, a beam of light shone on this side, a large area was illuminated, and Raven soon saw a behemoth slowly moving towards this side, that thing had a round body, more than 150 meters long, and its whole body was jet black, it was really a submarine!

The lights weren't gathered near Raven, the place where he was was very hidden.

The submarine was constantly releasing sonar waves, as if it was looking for something. Its speed has not changed, and it has been moving at a constant pace, even when passing by Raven's place.

Raven quietly watched as the submarine swam past, finally making sure he hadn't been discovered.

Xingli knew that the submarine was a Sea Soul model, but this type of submarine had a distinction between conventional power and nuclear power, and there was no difference in appearance at all, so Xingli couldn't tell whether the submarine was conventionally powered or nuclear-powered.

However, since there is a certain possibility, Raven will never miss this opportunity. Nuclear fuel is important to him, and he has to get it anyway.

The other party did not find him, but he found the other party, which was extremely beneficial to him.

Without further ado, Raven immediately slowly swung his tail and swam up, quietly approaching the submarine from behind.

Backbite...... Backbite...... The submarine's sonar system was constantly probing everything around it.

However, Raven was following him, but the other party could not detect him. (To be continued.) )
