Seeing such a huge shadow on the ground, Chen Xin knew that there must be a big guy behind him who could move, "Could it be that he is really a crow's mouth?" Sure enough, you can't set up a flag! ”

Although he was so apprehensive in his heart, Chen Xin really didn't dare to look back, sometimes the fluctuations in spiritual power caused by his gaze were easily detected by awakened creatures, which had been demonstrated and confirmed even in the old era.

Su Wan naturally knew this theory, and the hand covering Chen Xin's mouth slowly moved to Chen Xin's hand, pulling Chen Xin to slowly retreat towards the underground passage behind.

The hand was pulled by Su Wan, which made Chen Xin suddenly have a strange feeling in his heart, "This is ...... How long has it been since you've held a girl's hand? ”

Although he had been carrying Su Wan before, he had always paid attention to not touching Su Wan's exposed skin, and he had been chased by zombies all the time, so Chen Xin didn't have the heart to think about some of them.

The two people who walked into the underground passage again bumped into Zhang Baixin and them, and the leader of the 3 group asked strangely, "Why did you come back again?" ”

Su Wan made a silent gesture and whispered, "There's a giant zombie outside, let's wait a while before going out." ”

Chen Xin didn't actually see the zombies, but he was pulled into the passage by Su Wan when he saw a huge shadow, so he didn't interject, but Su Wan's words were enough to make everyone believe it.

"Make a battle plan? Or do you want to deal with the 'tail' in the back first? Group 3 pointed to two replicas looming in the distance behind them.

Su Wan also had a headache, she didn't know what the huge zombie outside was capable of, if her perception was very keen, they would definitely be noticed when they were fighting with the clones in the passage, and then there would definitely be no possibility of tactical raids.

"If it is more than 5 meters tall, it must be a mature body, and there can be no exceptions." Chen Xin saw that everyone actually had the idea of fighting with that big zombie, and he didn't care about revealing some knowledge, so he hurriedly added.

"Mature?" The leader of the 3 group looked puzzled, but the "sunspot" on the side looked solemn.

"The Federation of Country A once issued a "Zombie Statement", which is also the only authoritative document on zombies issued by the government in the old era. There were predictions about the basic form of zombies inside, the evolutionary body we encountered before, and the mature body outside. And, of course, there is the knowable completeness. Chen Xin said angrily, sighing, quite a few mercenaries of the Titan Company didn't even know this knowledge, and they were a little worried.

"Are you sure the ones out there are matures?" Su Wan stared at Chen Xin and asked.

"If it's more than 5 meters." Chen Xin didn't see it, so he could only say so.

"Visually, it's about 6 meters tall. But! Is there any theoretical support for using 5 meters as a basis for classification? Su Wan was a little curious, and even the "sunspot" on the side was also a little curious, the two of them had read a lot of research literature related to zombies, but they had never seen similar theories.

"Genetic Limit Theory. No matter what level of zombies there are, they all mutate and evolve based on human genes, so in order to continue to survive, they must break through the genetic limit. Dr. Tonya Ivan, who has been in the north, has quantified this indicator, which is reflected in the height of exactly 5 meters! Chen Xin sneered, even if Su Wan was his future research director and a fair-skinned and beautiful researcher, he still couldn't tolerate anyone questioning his biology expertise.

"I know Dr. Ivan, and together we worked on a formula for quantity at the beginning of this year, but I've never heard him talk about it!" Su Wan clasped her hands to her chest and stared at Chen Xin coldly.

The leader of the 3rd group also had a headache, not long ago, Dr. Su Wan let herself speak quietly, but now she herself looks like she is going to quarrel with Chen Xin, although listening to the content is just an academic argument, but it is a fact that the voice is getting louder and louder.

"Heizi" ignored the quarrel between the two of them, and took out a dagger from his military boots, looking at the style that Zhang Baixin used to break through before, and he didn't know what

When he took it in his hands.

The leader of Group 3 also knew that the person in front of him was definitely not a sunspot, because as a mercenary, it was impossible for his skin to be so white and delicate.

Yes, it is not a normal thing for a mercenary's skin to be described as white and delicate, but when this guy broke through, the hood was taken off, although it was immediately put on his face again, but the skin exposed in an instant made the leader of the 3 group very uncomfortable.

Their mercenary squad doesn't know when someone infiltrated! And several team leaders didn't know, if it wasn't for the infiltrators themselves exposed, no one would have been able to find out!

But just like that, with a white-skinned and delicate guy, he actually took out Instructor Zhang's dagger in front of his eyes, and quietly rushed towards the replicator who was already extremely close!

"Brush", the two parties met very quickly, but the leader of the three groups only saw the shadow of the dagger flying back and forth twice, and the two replicants fell to both sides, making two "dong" sounds one after another.

The sound of the corpse falling to the ground finally attracted Chen Xin and Su Wan's attention, and they saw that "Kuroko" was standing in the middle of the two clone corpses, playing a knife flower.

Chen Xin swallowed his saliva fiercely and muttered to Su Wan, "Are your subordinates so fierce?" "Although the two clones were also seriously injured, it was difficult to say that he could solve them without injury in a face-to-face hand-to-hand fight, but the person in front of him had no way of getting rid of it in such a short time.

Su Wan didn't pay attention to Chen Xin, but walked to the "sunspot" who took off her hood, and said expressionlessly, "It's you?" The board really values me. ”

"It was arranged by the chairman himself." Kuroko put away the dagger and smiled, revealing a mouthful of white teeth.

"I told him that I don't need him to get involved in my business!!" Su Wan seemed to be a little excited, and her fingers were almost pointed to Kuroko's nose.

"You'd better tell the chairman about this in person." In the face of Su Wan's somewhat rude behavior, Kuroko did not have any dissatisfaction, but showed more white teeth.

"I feel...... I think I know some kind of secret secret? Chen Xin turned his head sideways to the leader of the 3 group and said, "Does your chairman like Su Wan?" The domineering president and his cold subordinates who can't handle it. ”

The leader of the 3rd group turned his head and glanced at Chen Xin, looked up and down, "Dr. Chen, you are the most serious along the way, are you really a doctor of biology?" ”

"Serious double doctor! ......" As soon as the leader of Group 3 said, Chen Xin felt that he had no way to refute it at all, because since the crossing, he was really like this, often saying things that even he felt frivolous. But before the time-travel, he was not like this in the university laboratory, on the contrary, he had always been known for his reticent speech.

Chen Xin was a little silent, maybe he subconsciously regarded this world as a game, or a place that did not belong to reality, but the wounds on his body clearly told him that this was the real world.

"Director Su, there's a big guy outside, should we discuss it first?" Chen Xin walked up to Su Wan and asked politely. When he used to work in college, Chen Xin knew that the "domineering president" could still be reasonable, but their lover, lover or female assistant belonged to the absolute unprovoked, not only would they bring big trouble, but even the "domineering president" would become unreasonable.

"The highest place here is only more than 3 meters, and if that guy is 6 meters tall, won't he be able to get in?" The leader of Group 3 also followed Chen Xin.

Su Wan rolled her eyes and simply ignored him, Chen Xin turned her head and explained, "6 meters tall doesn't mean you can't enter this place." Big brother, I think you are 1.8 meters at most, is there a place where you are only 1 meter high, and you can't get in? ”

The leader of the 3rd group was a little embarrassed, this was indeed a very simple question, if he hadn't been carrying Zhang Baixin on his back, he would have wanted to scratch his head.

Suddenly, he felt a scream behind him!

Turning around sharply, he saw that the backpacker warrior was rolled up by a long red "meat snake". There were barbs on the flesh, which were deeply pierced into the backpacker's body, and were dragging the backpacker towards the back at great speed.

Chen Xin and Heizi had already jumped away with the long "meat snake", and with the light outside the passage, several people finally saw what the long "meat" was.

It's actually the big guy's "tongue"! I don't know when, the "big guy" has already gotten into the passage, lying half-kneeling in front.

Chen Xin looked at the "big guy" that Su Wan found, there was not even a little skin on his face, and he could directly see blood-red muscles squirming, and half of the backpack warrior's body was already in its mouth, still weakly making sounds like "help me".

Chen Xin could also see that the facial muscles of this zombie were almost no different from those of humans, and when chewing the backpack warrior, the masseter muscles and temporal muscles changed very obviously. Of course, the bite force must also be amazing, because the diameter of the masseter muscle is significantly much larger than that of humans! Moreover, the fact that half of the backpack warrior's body can be easily crushed is also proof of this.

The position of the orbicularis oculi muscle of the "big guy" is very large because there are no eyelids, and the whites of the eyes are covered with bloodshots, combined with the blood that keeps flowing down from the corners of the mouth, which makes Chen Xin feel a little creepy, thinking about whether he has pulled his legs and ran first.

"There was a voice behind me, I was afraid that the replicator hunting party would catch up, so I brought Dr. Su over. What is this ......?" The leader of the 3rd group carried Zhang Baixin on his back, the speed of movement was not fast, and he was a little out of breath, and as soon as he looked up, he saw the "big guy" who was tasting the backpack warrior, and his face was full of horror.

"Anyway, it can only eat one person at a time, let's rush together, who dies and who lives depends on the destiny of heaven!" Chen Xin heard that there might be a replicator behind him, so he gritted his teeth and made a suggestion.

"Humph!" Su Wan glanced at Chen Xin and let out a disdainful voice, "Poplar, the front is top." ”

After speaking, Chen Xin saw that the "Poplar" sent by the chairman of the Titan Company stood in front of Su Wan without fear, and he was also at the front of the entire team, but Su Wan put her hand into the pocket of the white coat.
