After a while, Chen Zhidong lowered his voice and said, "The other monsters are easy to deal with, but there is also a alien monster, although it is only a juvenile, it is also difficult to deal with. ”

"I'll snipe a few other monsters first." Ouyang Shaoyu had already assembled a special sniper rifle as he spoke, and set up the sniper rifle to aim at the rest of the monsters with a very standard action, and Chen Zhidong could only give orders.

"Kill it, everyone is ready to fight." Chen Zhidong nodded and agreed to Ouyang Shaoyu's sniping without thinking.

Hearing this, Li Li was stunned, his face was stunned, it was not easy to snipe such a monster silently at such a distance, he looked at Ouyang Shaoyu suspiciously, and said secretly in his heart: "This military doctor is too confident, Chen Zhidong, the captain, actually agrees with him to do this." ”

Although he was puzzled, he didn't say anything, being able to join the Eastern Divine Sword was definitely not an ordinary person, and of course he couldn't look at it with ordinary eyes.

After a few faint muffled sounds, Li Li scanned through mental power, and found that except for the alien monster, the rest of the monsters were quiet, not moving, and quietly guarding the research institute like statues, seeing this situation, he couldn't help but take a few more looks, Ouyang Shaoyu, the military doctor who was lying on the ground and did not move, secretly thought in his heart: "If this kid sneaks up on himself, I'm afraid the end will not be much better than these monsters." ”

"Shaoyu, aim at the alien monster and the rest of the people and prepare to fight." Chen Zhidong's eyes were fixed on the alien monster outside the door of the research institute, and his face suddenly became extremely solemn, and the next thing was the real battle.

Just when Ouyang Shaoyu was aiming at the alien monster and preparing to shoot, a low roar suddenly came from a distance, the alien monster turned his head to look in the direction where the sound came from, and then ran quickly, Li Li frowned and involuntarily looked at the direction where the voice came from, this sound actually made Li Li feel dizzy, this roar was actually mixed with violent mental power fluctuations, he quietly observed everyone's expressions again, this observation surprised him again, everyone didn't seem to feel anything about this voice, and couldn't help but guess more in their hearts:" Could it be because of the reason for turning on the mental power scan? ”

"Very good, ready to enter the research institute." Chen Zhidong said excitedly when he saw the alien monster leaving the research institute.

In this young man codenamed "Tank" took the lead, the whole team spread out in battle formation and walked quickly towards the research institute, Li Li looked twice more when he passed by the giant long-tongued crawler next to him, and found that the body of the head monster was bubbling with a trace of cold, it was obvious that the sniper bullet just now did not know how strong the ice attribute energy was attached, Li Li asked himself that he was also a fourth-order master, he could not kill these monsters with one blow.

Li Li looked at the dead monsters and wanted to go up and take out the crystals, but he still held back, after all, the whole team didn't even look at the corpses of these frozen monsters, and he couldn't help laughing at himself: "I really have the idea of a small peasant." ”

The Thunder Squad quickly entered the research institute, and after entering it, it was not the "tank" that took the lead, but Ouyang Shaoyu walked in the front, Ouyang Shaoyu seemed to be very familiar with this place After walking a lot out of the corner, everyone appeared outside a heavy metal door, and he took out an instrument from his pocket and inserted it into a black numeric keypad next to the metal door.

After a while, the digital keypad of the black screen lit up, Ouyang Shaoyu quickly pressed a series of numbers on the keyboard, and after a while, the metal door slowly opened, revealing a dark corridor, Ouyang Shaoyu entered quickly without speaking, Chen Zhidong waved his hand and everyone entered the dark corridor together, when the last person also entered the corridor, the metal door slowly closed, and the lights in the corridor were all lit up within a few seconds of the door being closed.

This is a metal corridor, and there is a heavy metal door not far from the corridor, this time Ouyang Shaoyu did not have the trouble of entering the first door, but directly pressed the "Call Management Center" button in the lower right corner of the numeric keypad, and after a while, a pleasant voice came from the speaker on the keyboard: "I didn't expect you to come very fast." ”

As he spoke, the metal door slowly opened, and it seemed that the metal door was controlled by the survivors inside.

In this way, after the group walked through 5 metal doors in a row, they entered a vast underground hall, and as soon as they entered the underground hall, Li Li was stunned, there were many specimens of various monster corpses, most of which Li Li had never seen.

Ouyang Shaoyu led everyone to walk in a certain direction of the underground hall, and soon came to a laboratory, Ouyang Shaoyu gently pressed a button on the door of the laboratory, and the door suddenly opened, and there was a young beauty wearing a white coat, wearing eyes, and a graceful figure was watching a slice under a high-powered electron microscope.

The moment he saw this beauty, Li Li was stunned, it was too different from the image of a task such as a doctor and an expert in his imagination, he originally thought that it should be an old man in his sixties and seventies, with a scholarly demeanor, but he didn't expect it to be such a young woman, and when he saw the monster inside the transparent tempered glass opposite the young beauty, his face suddenly changed, this monster he had seen, it was the humanoid monster who almost killed him in Yunxian.

I saw the humanoid monster lying quietly on the test bed with its eyes closed, several tubes inserted into its body, and the liquid in the tubes continued to be injected into its body, and its chest was still slightly undulating to prove that it was still alive.

"You've seen this monster." A pleasant voice interrupted Li Li's thoughts, and he saw the beautiful doctor put down the instrument in his hand and walked over, looking at him with clear eyes.

"I've seen it once." Li Li's heart moved, and he said expressionlessly.

"It's good to survive." Dr. Beauty said slowly, I don't know if this is to praise his ability, or luck, or both.

"Doctor, it looks like you've been studying these monsters for a long time." Li Li stared at the humanoid monster lying on the test bed, and sneered, it has only been half a year since the disaster broke out, but this underground research institute has been established for at least a few years, it seems that they have known the news of the disaster for a long time.

"Almost two years." The beautiful doctor glanced at Li Li, smiled lightly and said, "And my name is Cheng Xin, you can call me by my name without calling me Dr. Cheng." ”

"Hmph, you guys have done a good job of hiding this, and you don't have a word of it." Li Li snorted coldly, there was a hint of anger in his eyes, when he entered this underground hall and saw all kinds of monster samples, he knew in his heart that the disaster had been expected a long time ago, and he was very angry when he heard Cheng Xin's exact answer, and the sudden disaster almost killed him.

"If you say it, you're only afraid that before the disaster breaks out, humanity will be in chaos, and before the monster appears, we will have completely collapsed." Cheng Xin seemed to see Li Li's thoughts, and smiled slightly, she could understand Li Li's thoughts, but everyone's standing height was different, and the distance was also different.

Li Li sighed and didn't speak, he had to admit that this was indeed the case, if people had known that the monster would appear two years ago, the society would have been in chaos a long time ago, and it would not have been possible to have two years of preparation time, waiting for the arrival of pain is more painful than the pain itself.

After a moment of silence, Chen Zhidong said slowly, "Dr. Cheng, it's time for us to protect your retreat." ”

"Wait a minute, I'll change my clothes and leave." Cheng Xin said that he kept a smile on his face and walked towards the room, except for Ouyang Shaoyu, everyone else had a stunned expression, and when did they still pay attention to their clothes like this.
