It was still Chen Xi who opened the box, but the props that came out surprised the two. The golden box was actually a black ID card with gold trim.

"Advanced Permission ID Card - Arella's ID card as a high-level official of the Black Dragon Base has access to more than 90% of the institutional facilities in the base."

In the silver box, there was a strange firearm full of sci-fi style, like a gun and a grenade launcher, and in front of the muzzle there was a small pot lid like a satellite antenna.

"Sonic Annihilation Cannon - a special weapon system in the body of the biological mechanical Tyrannosaurus rex, due to the loss of the energy system support in the body of the Tyrannosaurus rex, this weapon only has a one-time chance of use."

Both are special props, and one of them is a prop that opens a special place at a glance as soon as you see the ID card. The power of the sonic annihilation cannon had just been seen by the two of them, and it was obviously an existence similar to an ultimate. However, the fly in the ointment is that it can only be used once, and it seems that it must be left at the most critical time.

The two were studying the two new props, and a secret door in the hall opened again, and the two glanced at each other and walked into the secret door together.

This time entering the secret door is still a secret passage, but this time the passage is all the way down, and the two have been running down quickly, and they have come to the end of the secret passage after about ten minutes.

When you open the metal door at the end of the tunnel, you will see an empty corridor. The walls and floors are silvery-white metal, and the ceiling glows with a soft milky glow. Seeing that there were no enemy soldiers guarding the corridor, the two quietly walked in.

Entering the hallway, it became clear that the left side extended to the depths of the base, and a short distance to the right was a wall, which was obviously a dead end. At this time, the red arrow that the system prompted the direction also appeared, flashing to indicate the left, and Fei Kun raised his foot to walk to the left. Chen Xi grabbed him.

"Fatty, wait!" Chen Xi shouted, then walked to the wall on the right and looked at it carefully.

"It's just a wall, what's there to see." Fei Kun asked puzzled.

Chen Xi pointed to a faint mark on the metal wall: "Look at this." ”

Fei Kun looked at it, and it turned out that there was a faint small palm print on the wall, and it was impossible to see it if he didn't look carefully.

"All the walls along the way are immaculate, there is no trace, but here there is a very abrupt half of a palm print, as if a greasy hand has touched this wall, there must be some mystery in this. Chen Xi explained to the fat man while clasping the gap in this wall and looking for something.

Sure enough, when Chen Xi's fingers slid into a gap, it felt as if he had touched something. With a beep, the wall crackled and split from left to right, and it was still a wall just now, but now it has become a closed metal door.

"Okay, how good you are kid!" Seeing this scene, the fat man said happily.

"If it's amazing, you have to go in." Looking at the tightly locked door, Chen Xi racked his brains to think about the way to enter the door suddenly had an idea, saw the card slot on the hidden position on the right side of the door, and immediately took out the ID card, and swiped it with a "poof".

"Ding Dong, the gamer discovers the secret area of the Black Dragon Base Area C, and the two players will be rewarded with a chance to draw a card each. Area C is also the research and incarceration area of the Black Dragon Base. Dr. Black Dragon imprisoned three of the world's top scientists here, hoping to force them to work for Karp Corporation. ”

"Ding, because the gamer discovered Area C of the hidden area of the Black Dragon Base, start the hidden mission of the game."

"Hidden Mission: Rescue - Rescue scientists imprisoned in Black Dragon Base Area C, and players will receive significant rewards for each person successfully rescued. (Warning, once the guards in Section C find the player, the guards will kill the scientist as soon as possible, and once all the imprisoned scientists are dead, the game will automatically fail, and every time one scientist is rescued, there will be a certain amount of punishment.)

Hidden missions? The two looked at each other, both confused. Now, I can only bite the bullet, and the two of them quietly entered the door, and sure enough, after entering, I saw a big C on the wall. Sure enough, this is Zone C.

This Area C is indeed a research and development area, and there are laboratories on both sides of the corridor, but they are all empty. After walking a short distance, he spotted the situation at a bend in a corridor.

The two of them secretly looked in, and saw that at the turn of the corridor was a closed research room door, and two black dragon guards with guns were on guard as if they were facing a great enemy. The two of them looked at each other and knew that they had found the right place.

The fat man's hand slashed down, meaning that he was about to rush over and make a move, but Chen Xi shook his head. The long distance around the corner of the corridor makes it difficult to eliminate the two Black Dragon Soldiers without letting them find out, and it is clear in the system prompt that once they are discovered by enemy forces in Area C, immediately execute the three hostages, and the mission will fail.

The fat man pointed to his head, meaning to ask Chen Xi what he could do. Chen Xi was thinking about it while checking his prop column, and suddenly he found something, he was overjoyed, and immediately took out the prop, and Fei Kun looked at it, it was the magazine that he didn't know what to do.

Chen Xi immediately put the book lightly on the ground, pushed it out slightly, and showed a corner at the corner of the corridor, and then withdrew with the fat man one after another, waiting for the enemy to take the bait, and success or failure was decided here.

But it was said that the two black dragon soldiers guarding the secret research room were guarding the gate, and suddenly, the soldier who was closer to the corner of the corridor saw the corner of the magazine, immediately said hello to his companion, and slowly paced around the corner.

He walked around the corner, looked down and saw that it was a yellow magazine, and was overjoyed, hurriedly lowered his head and picked it up, and was flipping through a page, when he suddenly felt a huge force grab his neck and drag it directly.

It was Chen Xi who was propped up on the ceiling who grabbed him by the neck, and he saw that the soldier had already flown down when he leaned over to pick up the magazine, and when the soldier picked up the magazine and got up, one hand stretched out like lightning, grabbed the soldier's throat and dragged him over, and at the same time, a divine ape fist in his left hand had been swung out, hitting the soldier in the chest.

The punch was so good that it pierced the unfortunate man's chest, and he immediately tilted his head and died without saying a word.

The soldier who remained outside the door of the research room could not help but be suspicious when he saw that his companion had not returned for a long time, and suddenly saw a hand of his companion stretched out from the corner and beckoned to him. He immediately walked over with a gun, and as soon as he reached the corner, he was greeted by two fierce attacks.

"Yay!" Chen Xi and Fei Kun clapped their hands excitedly, and then quickly walked to the door of the secret research room, Fei Kun was about to swipe the access control card, Chen Xi stopped him, attached to Fei Kun's ear and said: "I don't know what is going on in the research room, it is likely that there will be enemies guarding it." As soon as the door is opened, the middle line of the research room shall prevail, and I will kill the enemy as soon as I see it. ”

The fat man nodded, and then saw Chen Xi standing on the left side of the gate, ready to make an OK gesture to him, and the fat man immediately swiped the card.

With a "beep", the door of the secret research room slid open to both sides, and sure enough, there was a prison in the middle and back of the research room, and there were two black dragon soldiers standing with guns standing on the left and right next to them. When the two soldiers saw the gate suddenly open, they were both stunned, and at this moment of lightning, Chen Xi and Fei Kun, who had been prepared, immediately made a brazen move.

Before the black dragon soldier on the left could react, his head had been hit by a tiger roar, and then Chen Xi had already jumped up, and another divine ape fist slammed into his temple, killing him instantly.

That Fei Kun was also a laser death light that pierced through the face door of the black dragon soldier on the right, and then three blazing light bullets shot out in a row, completely destroying his residual blood.

At this time, the two of them had the strength to look towards the middle, but they saw that the prison in the middle did not have a traditional iron fence, but orange laser beams, fortunately there was also a card slot next to the laser beam. In the cell of about 40 square meters is a middle-aged man in a suit, with black curly hair, elegant appearance, a huge nose that is particularly eye-catching, a black beard on the chin, and a white coat that shows his scientist and scholarly temperament. At this time, he was looking at Chen Xi and Fei Kun through the prison of the laser pillar of light, his face full of surprise.

Chen Xi quietly made a probe and immediately got the information of this person.

"Dr. Skyhouse - Before Karp launched the Biochemical Apocalypse to take over the world, the world's most famous doctor of artificial intelligence was kidnapped and imprisoned by Dr. Black Dragon after the Biochemical Apocalypse, and was forced to work for Dr. Black Dragon's research."

Well, it looks like we've managed to free a hostage! Chen Xi gave the fat man a look, and the fat man immediately swiped the card slot in the prison with Arella's advanced ID card, and the laser beams disappeared instantly, and the big-nosed Dr. Skyhouse immediately walked out and asked excitedly: "Warriors, thank you, are you fighters of the underground resistance?" ”

Chen Xi and Fei Kun nodded at the same time, not knowing what to say for a while.

At this time, the system prompt sounded in the minds of the two of them at the same time: "Ding, congratulations to the gamer for successfully rescuing Dr. Skyhouse and getting a gacha reward." ”

Oh yes, that's it! Chen Xi and the fat man immediately smiled.

At this time, Skyhaus continued to say anxiously: "Heroes, there are two doctors imprisoned behind this door, they are the greatest Dr. Brive father and daughter of mankind before the cataclysm, please save them, the wisdom of their father and daughter can provide a great boost to resist Karp Company and save human civilization!" ”

Chen Xi looked at the gate that Skyhouse was pointing at and asked, "Doctor, do you know how many guards there are inside?" ”

"Six, please kill all the guards as soon as possible, otherwise they are likely to poison the Doctor's father and daughter!"

This is the system once again prompting the player, six guard soldiers to be killed in an instant, but that is almost an impossible task, the black dragon guard is not the kind of low-level blue-clothed soldier in the first level, its life is two and a half times the length of the blue-clothed soldier, Chen Xi needs to hit two ordinary skills to eliminate one, the same is true of Fei Kun, there are actually six guards in the room this time, and it is almost impossible to kill all six enemy soldiers at the first time.

Chen Xi thought for a moment and asked, "Doctor, can you tell me how the six guards are distributed." ”

Skyhouse thought for a moment, then replied, "I've seen that room a few times, two on the left, four on the right, and the two cells in the middle are the Briv father and daughter. ”

Left two, right four! If this is the case, then there may be a glimmer of hope for victory, Chen Xi said secretly in his heart. He looked at the fat man with an eager face and asked, "How is it?" Fatty, should we give it a try? ”

The fat man smiled: "It's all here, do you still need to ask?" Of course, I gave it a go. Die and die, live and live! Chen Xi, if you have any good plans, tell me quickly. ”

"Okay, since you say so, then let's ......" So Chen Xi whispered to Fei Kun about the method he had come up with. At this point, Dr. Skyhaus did his job as a game NPC, standing there motionless, just looking at the two of them anxiously.

At the moment, the two of them have finished their planning, and Chen Xi is still on the left side of the door of the second research room, and Fei Kun is on the right, holding the ID card and swiping it lightly.

"Toot ......" The door of the second laboratory also slowly opened.
