Pang Xiaonan leaned closer and asked Oda Lima, "How are you sure that it is a Canglong, I mean, what evidence is there that it is a Canglong? Is it possible that it is another mutant species?" ”

Oda Rima clasped her hands in front of her chest, looked at the biological samples under the microscope, and held her chin in her right hand and said: "It is true that the mutated giant lizard may reach such a large size, but this environment is not like an environment that can cause mutation, we all know that biological mutation is most commonly caused by radiation, but since we entered the Bloss Disk, we have not felt anything unusual in the environment here, I mean, we have only been attacked by different creatures, but we have not encountered environments such as storms, volcanic eruptions, and whirlpools." ”

Pang Xiaonan added: "Is it possible that there is a genetic mutation?"

"That's too much of a coincidence. Rita Ruma frowned, "Gene mutation refers to the phenomenon of sudden, heritable mutation of genomic DNA molecules, genetic mutation can occur at any stage of development, mutation refers to the change of the nucleotide sequence of the genome of an organism, virus or extrachromosomal DNA. These include base substitutions with even one base change, DNA insertions, DNA deletions, or sequence changes caused by DNA duplications. Some mutations are heritable, and the mutations that occur in the germ cells can be passed on to future generations. Mutations that occur in non-germ cells, i.e., somatic cells, called somatic mutations, are non-hereditary mutations. Errors in the DNA replication process can lead to mutations. Mutagens such as chemical and environmental factors (ultraviolet light, etc.) can also induce mutations in organisms......"

Pang Xiaonan interjected with a smile: "Professor Oda Lima, can you please make it simpler, your proper nouns are too difficult to understand, all of you here are scientists, but I haven't graduated from university yet......"

It's really embarrassing to talk to scientists without any knowledge, and I can't talk at all.

"I mean," Rita Yama looked at Pang Xiaonan, "It's understandable that the genetic mutation happened to a creature, but you see that since we entered the Bloss Circle, the creatures that have attacked us several times are prehistoric behemoths, this is too much of a coincidence, it is impossible for all the creatures here to mutate, right?"

Pang Xiaonan nodded, "What you said makes sense, so why can this biological specimen be sure that it is Canglong?"

"When you were fighting it, we all saw the appearance of that monster, which was a lizard-like creature, but it had a little more physical upgrades than the lizard, such as its gills, which was also a guarantee that it could breathe in the water for a long time. Lima Oda struggled to recall the blurry images of the monsters she saw through the glass windows.

"Lizards are the most diverse group of reptiles (reptiles), with more than 4,000 known species worldwide, mainly in the tropics. The size varies greatly, from a few centimeters of Caribbean gecko to a Komodo dragon nearly 3~5 meters long. Some species of species known as snake lizards have degraded their feet, leaving only some traces of foot structures. Rita Lima felt the need to explain to Pang Xiaonan about lizards.

"Lizards are closely related to snakes, and there are many similarities between the two, such as the epidermis-derived scales, the cloaca anal hole is transversely lobed, the males have a pair of articulators, all oviparous (or partially ovoviviparous), square bones can move, and so on. ”

"Some people think that the lizard and snake are divided into four legs, while the snake has no legs. A pair of claw-like hind limbs can be found on both sides of the cloaca anal hole of some python snakes, while snake lizards, with no traces of their feet in appearance, are often mistaken for snakes. ”

Oda Rima looked at Pang Xiaonan: "In terms of the characteristics that are easy to identify in appearance, the difference between a lizard and a snake is: 1. The left and right halves of the lizard's mandible are combined by bone sutures, and they cannot move and their mouth cannot be opened. The left and right halves of the snake's mandible are connected by ligaments that can be pulled apart from each other, which is one of the reasons why the snake's mouth can be opened so wide. 2. Lizards generally have limbs, and even if the limbs are degenerate, there must be remnants of the forelimb girdle (shoulder girdle) in their body. Snakes generally do not have limbs, and even if they have remnants of hind limbs, they do not have any remnants of forelimb belts in their bodies. 3. Lizards mostly have movable upper and lower eyelids, and the eyes can open and close freely. The upper and lower eyelids of the snake heal into a transparent membrane that covers the outside of the eye, and it looks like the snake's eyes are always open. 4. Most species of lizards have wide, thick tongues. The tongue of the snake is very slender, the tip is very forked, and the base is located in the sheath, which often stretches and contracts through the notch at the front of the mouth, so as to collect "smell" molecules from the outside world (mainly food) and send them to the hoe to produce the sense of smell. 5. Lizards generally have external ear holes, and even if they don't, the eardrum can be seen from the outside. Snakes do not have external ears and do not have eardrums, so no traces of auditory organs can be seen on their appearance. 6. The tail of the lizard is longer, generally equal to (or only slightly shorter) than the length of the head, or 2-3 times the length of the head. The tail of the snake is relatively short, 1/2 to 1/4 of the body length (i.e., the tail length accounts for 1/3-1/5 of the total length). ”

"The difference between a lizard and a snake can be cited if you compare it in detail from the anatomical structure. Although there are many differences between the two, they are both at the same stage of development and very similar in terms of the degree of evolution of organic structures in the development of the animal kingdom. Therefore, almost all taxonomists in the world at present place them in the order Lepids under the class Reptile, distinguishing them into two different suborders. "As a paleontologist, Rita is a meticulous researcher of ancient races such as lizards and snakes.

"What are the specific characteristics of the lizard's appearance?" Pang Xiaonan listened with relish, hoping to know more.

Oda Rima thought for a while, and then listed several appearance characteristics of lizards: "The body of lizards is generally divided into four parts: head, neck, torso, and tail. The body epidermis of lizards is leathery scales, and some species also have small bony plates under the scales, such as skinks and snake lizards. Lizards have small teeth, and the shape and length of their tongues vary depending on the species. The eyes are more developed, and some species also have cranial parietal eyes, except for most geckos, the eyelids are motile and motile in general, and the burrowing type of eyes are mostly hidden under the skin. In the ears of lizards, the eardrum is mostly exposed, and the eardrum is developed. The left and right mandible bones are united by bone sutures, so the mouth should not be opened too wide. Lizards have elongated bodies, thick and well-developed hind limbs, and have membranes at the bottom of the soles of their feet that can be opened or retracted. As it runs on the surface of the water, these membranes open, increasing the contact area between the sole of the foot and the surface of the water. ”

"So did that dragon just now have these characteristics?" Pang Xiaonan still didn't believe that there was such a big lizard.

"The basic characteristics are all there," Rita Rima said, pointing to the biological sample, "for example, this epidermis is almost 100% consistent with the leathery scales of a lizard." ”

"It looks like we're really in the prehistoric world. Pang Xiaonan's gaze drifted to the sea through the glass window of the cabin.

Pang Xiaonan returned to the deck, although it was already dawn, but danger was everywhere, he had to make sure that the surrounding environment was foolproof, besides, Lewis had been guarding for several hours, and he had to let him go back to rest.

Buktonlin had already arranged the personnel on duty, and there were four people left on the deck, Pang Xiaonan walked over and said to Buktonlin: "Captain, I'm back." ”

Buxton Lin turned his head to look at Pang Xiaonan, showed a rare smile, and said, "You have worked hard all night, so let's go back to the cabin and rest." ”

Pang Xiaonan shook his head with a smile and said, "I can rest on the deck." ”

"Are you sure?" Bucton Lin patted Pang Xiaonan on the shoulder, "It's that you can rest on the deck, or you can't sleep comfortably on the bed, listen to me, go and rest." ”

"Captain, I can better monitor the dangers around me on the deck," Pang Xiaonan pointed to the sea in the distance, "Maybe somewhere, there are even greater dangers waiting for us." ”

Buckton Lin frowned, what Pang Xiaonan said made sense, although the previous waves of danger have passed, unknown dangers may come at any time.

"Alright then, you can rest on the deck, thank you. Bucton Lin patted Pang Xiaonan on the shoulder again, turned around and walked back to the cockpit.

The first mate, Buenoski, had regained his helm, and Buchton Lin closed the hatch and asked, "We haven't deviated from our direction, have we?"

"Don't worry, Captain, I've been calibrating the direction, and I can't go wrong. Buenolski clutched the steering wheel tightly and looked ahead with both eyes unblinking.

"Are you well rested?" Buchtonlin was more worried about Buenoski's mental state.

"I'm rested, I'm in good spirits now. Buenovski smiled brightly at Buktonlin.

"Why haven't you seen the land yet? Isn't there any land in this Bloss Disk?" said Bucton Lin, looking at the vast sea, and muttered to himself.

"Captain, go and rest. A sentence popped out of Buenoski's mouth.

"No, it's too dangerous in the sea, I have to stay here. Bucton Lin pinched his sore eyeballs with two fingers, and his nerves were too tense for a day and a night.

"You haven't rested for a long time, and your body will collapse by then," Buenovski turned to look at Buctonlin, his hands gripping the steering wheel like iron tongs, "you are not in good spirits, and it will affect your judgment then." ”

Buenolski is right, a commander must always keep a clear head, but if you do not rest for a long time, your mind will be dull and easy to make mistakes.

"Hmm...... I'll admit you have a point," Bucton Lynn shook his head, which was now a mess, "maybe it's time for me to go and get some rest." ”

"Don't worry, I'm keeping an eye here," Buenoski pointed at Pang Xiaonan on the deck with one hand, "That kid has two hits, ordinary animals are not his opponents, besides, we have strong fire support." ”

Buenoski happened to see the last scene of Pang Xiaonan's fight with Canglong, and was shocked by Pang Xiaonan, and he was right, it was daytime, if there was danger approaching, it would be much safer than at night, and the Black Mamba Escort would be more sure to deal with it.

"Alright then, I'll go get some rest, and I'll leave it to you. If there is a situation, call someone to inform me immediately. Bucton Lin finally dragged his tired body back to his sleeping compartment, and without taking off his clothes, he lay down on the boat and closed his eyelids.

Pang Xiaonan's physical strength recovered quickly, he found a comfortable position to sit on the deck, and began to suck spiritual energy again. After fighting with Canglong, he consumed a lot of physical strength, and just ate a compressed biscuit, and there was something in his stomach, but he still had to replenish some spiritual power in preparation for the next fight with unknown monsters.

Everyone knew that Pang Xiaonan was able to sense the danger in the vicinity and acted as the radar of the "Flower of Bulos", so no one bothered him and let him close his eyes quietly.

Sniper Wu Yongqiang stared at the scope as he stood on the side of the ship directly in front of him on the deck, constantly changing the direction of the sniper rifle to ensure that no dangerous creatures were approaching.

Nandegrad and Zhao Guifei chatted quietly, Nandegrad said: "Pang Xiaonan, this guy is really a god, when he just came out of the sea, I carefully checked his body, and there was no wound, fighting with such a big animal, there was no wound, it was amazing." ”

When Canglong bit the "Flower of Bulos", everyone was woken up, and all the members of the Black Mamba Escort who were resting in the cabin ran onto the deck, ready for fire support at any time, so they all saw the scene of Pang Xiaonan and Canglong fighting.

"yes, to be honest, I don't even have the courage to jump. From time to time, Zhao Guifei took the scope to look at the sea in front of him to make sure that no unknown creatures approached.

"To be honest, I wasn't optimistic about him at first. Nandegrad leaned on the side of the ship with his hands and pressed his shoulders, "I see that he is so young, no matter how high his martial arts are, it is really blinding." ”

"I think Pang Xiaonan is unfathomable," Zhao Guifei followed Nandegrad's example, put his foot on the side of the boat, and pressed his leg, "You think, Pang Xiaonan is so young, he is still a student, so he joined our Black Mamba, if there is no outstanding ability, I think Black Mamba is not a place to raise idlers, and the bosses are not so kind to find someone to eat." ”

"yes, it seems that the chief instructor has a good eye. Nandegrad moved his shoulders from side to side.

"You mean, Pang Xiaonan was personally recruited by the chief instructor?" Zhao Guifei looked at Nandegrad curiously, as far as he knew, the Black Mamba members all went through countless rounds of screening before they could officially join, and most of them signed up by themselves, that is, through the recruitment interview process.

"That's right, the chief instructor Bei Dajun personally recruited it. "Nandegrad is an old man in the Black Mamba, and he knows a lot of inside information for the first time.

"This is not simple," Zhao Guifei knew Bei Dajun's strictness, "The person who can be valued by the chief instructor should not be simple, no wonder Pang Xiaonan's martial arts are so high." ”

"I also heard that Pang Xiaonan's martial arts are on par with the chief instructor's martial arts. Nandegrad threw a smile to Zhao Guifei.

Nandegrad and Zhao Guifei have worked together many times, so they are very familiar friends, the kind of comrades-in-arms who can entrust their lives to each other.

"So powerful?" Zhao Guifei's eyes were full of incredulity, but he quickly calmed down again, "Actually, judging from the scene where he just fought with the monster, it is not uncommon for him to have similar martial arts skills as the chief instructor. ”

Bei Dajun has fought many of his subordinates on the Black Mamba's training ground and has never been defeated, which is one of the reasons why the Black Mamba members believe in him.

"Yes, I didn't believe it before, when did the chief instructor lose? Otherwise, how could he be the chief instructor?" Although Nandegrad is a medical officer, he also has to participate in the training of the Black Mamba in case of emergency, "But after watching the real fight scenes of Pang Xiaonan, I believe that he should be the opponent of the chief instructor." ”

"The chief instructor won't recruit Pang Xiaonan because he can't beat him, right?" Zhao Guifei made up the process of Pang Xiaonan's entry into the Black Mamba, first of all, Bei Dajun and Pang Xiaonan had a dispute, and then the two of them fought, and they didn't know each other, Bei Dajun found that Pang Xiaonan was so young that he was almost as good as himself, so the hero cherished the hero and recruited Pang Xiaonan into the Black Mamba at any cost......

"I don't think it's just because of his martial arts skills that he was recruited in," Nandegrad turned to look at Pang Xiaonan, who was meditating, "Didn't you pay attention to his temperament?"

"Temperament, what temperament? We are a combat unit, the most important temperament is murderous spirit, right?" Zhao Guifei was a little confused, and he didn't know what kind of medicine was sold in the Nandegrad gourd.

"Leader's temperament," Nandegrad stretched out his right hand and pointed at Pang Xiaonan, "Don't you notice that he is very assertive? And his kind of leadership temperament is very comfortable." Nandegrad turned his head to look at Zhao Guifei, "I mean, our current captain, his leadership temperament is very majestic, but I just think that Pang Xiaonan's leadership temperament makes people involuntarily want to follow him to do things." ”

"When you say that, it does mean something. Zhao Guifei took a deep breath of fresh air, "As soon as he makes a move, we will support him." And he's really dead, if it weren't for him, we'd all be buried at the bottom of the sea. ”

Nandegrad pressed his elbows on the side of the ship, leaned his back against the side of the ship, nodded, and said: "Indeed, only a leader who charges into battle is a real leader, this kid is becoming more and more likeable." ”

"Look, look!" At this time, Wu Yongqiang pointed to the front and shouted.

Nandegrad and Zhao Guifei looked in the direction pointed by Wu Yongqiang at the same time.

It's land!

The first mate in the cockpit, Buenoski, also saw it, he stood taller than the others, and saw a group of reefs, and behind the reefs, there was a relatively large land, and the exact size of the island, which had to be seen closer to the boat.

Buenovski looked at the gauges, and the hands were still on the "0" scale of the dial, indicating that they were still inside the Bloss disc.

Buenovski's eyes were full of excitement, and after driving the ship for so long, he finally saw land.

Several people on the deck were also excited, and after experiencing several major dangers, this luxurious scientific expedition team was finally about to land on the land inside the Bloss Circle.

"Nandegrad, go and call the captain and report to him that we have seen land. Buenoski pressed the Bluetooth headset and arranged the division of labor among his teammates, "Wu Yongqiang and Zhao Guifei, you continue to observe to see if there is any danger nearby." ”

Although I saw the land, but the danger still could not be lifted, maybe this sea area close to the land, there are more dangers, at any time, the Black Mamba Escort cannot relax their vigilance, this is also the consensus of all the members of the Black Mamba Escort Team.

Pang Xiaonan also opened his eyes, although he didn't feel the large fluctuation of the aura, but he could clearly feel that the purity of the aura had changed somewhat, it was purer than before, so there was only one possibility, that is, the environment here was no longer the sea area before.

At the shouts of his teammates, he knew that he had seen land, and he walked towards the side of the boat, taking a closer look at the scene in front of him.

Large and small reefs are distributed on the surface of the sea close to the land, and they do not look like coral reefs, but are made of rocks, and behind the reefs, large pieces of land are faintly visible.

Pang Xiaonan took off Wu Yongqiang's Bluetooth headset, put it on his ear, pressed the switch and said, "First mate, you stop the boat first, and I'll go and investigate to see if there is any danger." ”

The "Flower of Blos" was approaching the reef, and Buenovski was hesitant to continue its development. If you don't understand what is going on beneath the surface, you will be in a dilemma if you hit the rocks.

To figure out the situation under the water, someone must dive into the sea to take a look, which is a very dangerous thing, and this matter, Pang Xiaonan is very suitable. Pang Xiaonan has already proposed it himself, so it couldn't be better.

"Got it, I'll stop the ship right away. Buenovski stopped the engine as Pang Xiaonan ordered.
