On the metal wall is the outline of a door, with twelve metal numeric keys on the side of the door, which are supposed to be used to enter passwords. There was also a small electronic display on top of the door with a bright red number: "10", I don't know what it meant.

Liu Fang saw the heavy metal door and groaned: "There is really a problem here, it seems that we have to find a way to open a passage above the wall before we can enter." ”

His eyes gestured to Zhang Xiaojiang, Zhang Xiaojiang smiled, raised the Thomson submachine gun in his hand, and just fired a shot, the bullet hit the door, splashing golden flowers.

However, in the next second, the ground under their feet shook slightly and sank down a little. Immediately afterwards, the bright red number on the electronic display became "9", and then it became "8" and "7。。。。。

"It's a countdown!" A flash of lightning flashed in Liu Fang's mind, and he suddenly shouted. “。。。。 There is danger! Everyone's block retreat! ”

This is supposed to be a defense mechanism built by the people in the laboratory to prevent outsiders from breaking in. As long as the person touches the metal door, the countdown of the electronic display screen on the electronic screen will start, and the correct password must be entered for ten seconds before the metal door can be opened safely, otherwise, as soon as the countdown stops, the defense will be activated!

The reaction of the others was not as good as liu fang zhang xiaojiang and li lao were still standing in front of the door of the metal wall and did not come back to their senses after being shouted by liu fang everyone ran back along the passage reflexively however. They have wasted several seconds, and before they can reach the elevator door, the number on the electronic screen has already reached "0"!

"Boom!"

A deafening sound came from behind, Liu Fang looked back, and a firelight in the passage rushed straight towards them, and at this moment, the corpses that were touched by the firelight were suddenly scorched.

Liu Fang gritted his teeth, and with a movement of his mind, a stream of water rushed to the sky, enveloping everyone!

The fire lasted for several minutes before it slowly stopped, looking at the surrounding wall, which was already charred at the moment, and by the wall, several people were leaning there, constantly panting, and outside their skin, a transparent film of water, constantly fluctuating.

"Whew" Liu Fang exhaled, and then, the water film on their surface shattered with a bang.

At this moment, they felt that they had just come back from the edge of the death line, sweating profusely, and Li Lao's back, because he couldn't dodge in time, was scorched by the flames, and looking at it made people breathe in cold air.

Just when everyone thought they had escaped death, suddenly a figure flashed at the entrance of the swarthy cave and rushed straight to Liu Fang.

Liu Fang looked at Wang Sifan and them, and didn't pay attention to him, however, he saw the color of fear in Wang Sifan's eyes, and his heart suddenly cooled!

Liu Fang didn't hesitate at all, he kicked the ground with the soles of his feet, jumped up violently, in the air, his waist was almost bent at ninety degrees, and the submachine gun in his hand swept towards the back!

The flame of the muzzle of the gun made Liu Fang see the appearance of the figure behind him clearly, this is a huge monster, like a gecko, about two meters seven or eight meters high, the length of the body with a tail but three meters away, a dark and shiny shell, a huge and long head extended to the back, the terrifying mouth is full of sharp teeth, and the most frightening thing is that his tail is full of sharp teeth, constantly waving, this is a monster that can scare ordinary people to death just by appearance!

Liu Fang saw him pounce on him, his mouth opened wide, and he wanted to devour him, however, Liu Fang's firepower suppression made him unable to raise his head for a while, and he retreated one after another, roaring from his mouth!

"Zhang Xiaojiang!" Liu magnified and roared, Zhang Xiaojiang naturally understood what Liu Fang meant, and instantly woke up from his surprise, the gun in his hand was aimed at the monster, and the successive bullets made the monster roar and fall to the ground!

Liu Fang took advantage of Zhang Xiaojiang's firepower to suppress, his body rushed over, a spear appeared out of thin air in his hand, he jumped high, his eyes were red, and the tip of the gun in his hand was aimed at the behemoth below, and his head was Liu Fang's target!

In the last life, Liu Fang had encountered this kind of monster, people called him a creeper, a mutated monster, reaction speed and strength, are extremely powerful, and the appearance is covered with a hard shell, so that he can ignore bullets, only the head, is his vital point!

So when Liu Fang attacked him just now, he lowered his head and resisted the bullet with his back!

However, Liu Fang's thoughts seemed to be pierced by this creeper below, he roared, his eyes were blood-red, and suddenly, Liu Fang felt a strong wind behind him, and a thick tail had hit Liu Fang's back hard!

Liu Fang felt a sweet throat, a mouthful of blood spurted out, and the whole person flew out like a cannonball, and at the moment of landing, a fat man appeared behind Liu Fang, and the two of them smashed to the ground at the same time, thanks to Zhang Xiaojiang's buffer, Liu Fang was fine.

At that moment just now, Liu Fang's spine was almost broken, and it was smashed on the ground, and it was either dead or injured, Liu Fang didn't have time to take care of Zhang Xiaojiang, and the water waves in his hand flew over, like a dagger, making the crawlers lying on the ground retreat one after another.

Just when Liu Fang was about to rush over, the creeper's figure flashed, and his tail kept shaking, so that Liu Fang had to retreat one after another, the creeper was extremely fast, Liu Fang could only see a black shadow, and then disappeared around the corner!

Liu Fang saw that he ran away, and did not chase after him, the speed of the creeper was extremely fast, and he could also attach to the wall, and he couldn't catch up with the Jedi, so he hurriedly checked Zhang Xiaojiang's injury.

At this moment, Zhang Xiaojiang wailed a few times on the ground, and then slowly got up and moved his body, but he looked like he was suffering from the rest of his life: "Fortunately, Lao Tzu has rough skin and thick meat, otherwise just now, this handsome guy would have burped!" ”

At that moment just now, of course Liu Fang knew how big his impact was, and when he saw Zhang Xiaojiang demonstrating the past with such a giggle, his heart warmed. Although Zhang Xiaojiang is usually timid and afraid of things, Liu Fang knows that he is a man in his bones!

Liu Fang saw that he was still talking like that, smiled, and then frowned again.

In his memory, the creeper only appeared a year after the end of the world, and now he actually appeared in advance, Liu Fang felt that his head hurt, in the previous life, his ability was upgraded to the second level, so he could barely defeat him, and now his ability has just awakened, and he actually appeared.

Touching his forehead, Liu Fang motioned for them to hurry up, after all, the speed of the creepers was extremely fast, and Liu Fang knew that he would definitely find them again, so he raised his spirit one hundred and twenty times at the moment!

It seems that this research base is not as simple as imagined!
