"Guo!" Delia's eyes flashed with hatred, and she snatched the gun from his hand, and aimed it at the D-class demon, and the moment it pounced, the gunshot rang out, and the black hole on its forehead smoked and fell straight down.

Ding Xuan secretly scolded her mother in her heart, this Guo Yun's sense of justice is too strong, in order to save a virtual character, he repeatedly put himself in danger.

She killed the last long snake and took out the last white life potion from the inventory, Delia shook her head at her, and pulled a needle out of her pocket: "This is the vaccine for the fish toxin, it took us years of hard work, the others are destroyed, this is the last one." She bit off the needle cap and stabbed Guo Yun in the neck.

The light red liquid was slowly pushed through his body, and his body twitched violently, like a fish on a chopping board. Ding Xuan wanted to touch him, but was stopped by Delia: "This is the vaccine that works." ”

The convulsions didn't last long, and after half a minute, the bruises on Guo Yun's face gradually faded, and he regained his vitality, and he touched his chest in disbelief: "I'm not dead?" ”

Ding Xuan stared, not angry, but amazed at his luck that he was so lucky, he could get a precious vaccine if he saved a person casually, and he had the title of "Yingyu Toxin Immunity" in his profile, and from now on, he would be the nemesis of D-class demonized people.

Is this the so-called stupid person a fool?

The earth shook suddenly, dust trickled down from the ceiling, and the sound of heavy footsteps like thunder shook everyone's eardrums.

"Merfolk!" The personnel in those organizations exclaimed, Ding Xuan turned around, and saw a giant fish with four thick legs walking towards the main control room. Its body was too large to enter the door. It opened its mouth and spat out a mouthful of bright green saliva. The gate and walls made of special metal were corroded into a large hole.

Mermaid: Fourth-order high-level alien beast, Attack Power: 1060, Defense: 950, Skill: Corrosive Liquid, Defense: Fire, Ice, can produce dark green gems.

Ding Xuan was so shocked that her eyes were about to fall out, the mermaid in the movie is an ugly monster that is half human and half fish, this mermaid is in line with the record in the "Classic of Mountains and Seas", but the book does not say that its size is comparable to that of a Tyrannosaurus rex! The scales on its body are the size of an adult man's palm. It flashed with a cold light, and the edges were as sharp as sharp blades.

"Sister Ding, be careful!"

Ding Xuan quickly jumped away, the position she was standing just now was corroded by the mermaid's corrosive liquid to corrode a big hole, she swung the battle spirit axe, a nether fire fell on the mermaid's body, the black mist-like flames wrapped it whole, who knew that it rushed out of the fire unscathed, and let out a baby-like cry from its mouth. Lunge at her. If you get hit or stepped on by this behemoth, you can make her a meatloaf.

As the mermaid got closer, she saw the fangs in its mouth, and she didn't look like a silver carp. The teeth were like piranhas, and she was short and rolled under it. The Spirit Axe in his hand slashed at its belly.

It has a soft belly and is the only place on its body that does not have fish scales. It looks white and tender, but when it is cut with a sharp weapon, it looks like it has been cut into cotton. When I pulled it out and looked at it again, I was unharmed.

Ding Xuan was chilled, its defense was so strong.

Enraged, the merfolk stomped on her, her head holding her and rolling under it. Guo Yun rushed over and slammed into its gills. The Finger Tiger, who was able to shoot the head of the E-class demonized person, could only leave a pinch-like mark in the soft flesh of his cheeks, and he didn't even shed a trace of blood, but his hands were cut bloody by the scales on his cheeks.

The mermaid turned his head and spit out a mouthful of corrosive liquid, Guo Yun rolled on the spot, but he could avoid it, a few drops of liquid splashed on his clothes, he quickly took it off, and his back was still corroded out of two small holes, and blood gushed out, shocking.

But this gave Ding Xuan a chance, she finally escaped from under the belly of the fish, looking at this almost invulnerable monster, her heart was racing.

It is able to defend against fire and ice, unless she has a fourth-order gem or higher, these two totemic-engraved weapons are ineffective against it, and she can only try thunder and lightning. Between the lightning and flint, a ball-shaped lightning bolt the size of a basketball had been condensed in his hand and threw it towards it. The mermaid is huge, the main control room is not large, it can't dodge flexibly, the lightning falls on its head accurately, the electricity crackles around its body, it hurts so much that people stand up, hit the ceiling, and the ceiling collapses a large piece, when the current dissipates, it just has a black face, and there is not much damage, but it is completely enraged, it is crazy to crash everywhere in the main control room, corrosive saliva is spit everywhere, a man in the organization was hit by the liquid, and it was instantly corroded into a puddle of pus.

Ding Xuan threw the thunderbolt at its face, and although it had an effect, it had little effect. This doesn't work, we have to find a way. By the way, the eyes, the eyes of the beast are very weak, a thunderbolt flashed in her palm, hitting its eyeballs, it seemed to sense the danger, closed its eyes, and the two golden scales blocked the lightning, this time there were no black marks.

Damn it! She hadn't broken through the fourth level yet, and she couldn't break through its defenses at all. Dodging the corrosive liquid sprayed by the mermaid, she suddenly saw the pistol in Delia's hand: "Guo Yun, how is your marksmanship?" ”

"Okay."

"Now is not the time for modesty, what the hell is it?"

Guo Yun dodged the mermaid's foot in embarrassment: "I have won the provincial shooting championship. ”

Ding Xuan rushed to Delia and snatched the pistol: "How many bullets are there?" ”

"There's only one left."

Then you only have one chance. Ding Xuan shouted at Guo Yun: "Can you last ten minutes?" ”

"I'll try my best!"

Ding Xuan hid in the bunker and calmed down, and the system suddenly prompted that a "key holder" had entered the trial dream.

"Key holder"?

Situ Qi seems to have this title as well?

The situation was critical, and she could not think about it, so she calmed down and began to inscribe on the pistol, where her nails passed, the golden light flashed and moved. It only took eight minutes for the totem to be inscribed, and a third-order gem was also inlaid.

The situation on the battlefield is changing rapidly, eight minutes is enough for Guo Yun to be seriously injured, seeing that the mermaid's soles are about to step on and crush him into a meat patty, Ding Xuan rushed over at a very fast speed, hugged him and rolled on the spot, and he was able to dodge a blow.

"Lend me that armor of yours!" Ding Xuan said loudly.

Guo Yun did not hesitate to take out the armor of the Guardian Heart God, Ding Xuan quickly put it on, and handed him the pistol: "Remember, hit it in the eye, success or failure is here." After that, a few ups and downs actually rushed to the mermaid's back, and his legs clamped his neck, and the defense power of the Guardian Heart Armor was 220, which was enough to prevent being cut by the fish scales on its body. She reached out and grabbed the scales from the merfolk's eyes and pulled them away with all her might, and the merfolk shook their heads angrily, trying to shake her off her body.

"Guo Yun, shoot quickly!" The armor was mainly on the torso, and the golden scales on the eyes were so sharp that they pierced her fingers and stuck into the bones, and if her body had not been strengthened, or if she was not wearing armor, the fingers would have been cut off long ago.

Guo Yun was covered in blood, leaning against the wall to stand firmly, he coughed up a mouthful of blood, raised the gun, because of the serious blood loss, his face was pale, his whole body was trembling, only the arm holding the gun was as stable as a stone carving. His eyes were staring at the mermaid who kept shaking his head without blinking, everything around him became irrelevant, no sound was in his ears, no scenery was in his eyes, only the movement of air could be felt.

"Bang", the bullet was fired, and a thin layer of water was wrapped around it, and the water vapor in the air condensed into it wherever it passed, leaving a trail in the air that could be seen by the eye.

Ding Xuan felt that her hands were not her own, she was thrown around by the mermaid, she was dizzy, and suddenly the strange beast under her let out a sharp wail, and stood up again, she finally couldn't support it, and rolled down from its back, the bones all over her body seemed to be scattered, and the calves and forearms with weak armor protection were cut into flesh and blood.

The mermaid's left eye was bleeding profusely, and the bullet not only shattered its eyeball, but also entered its brain, and the water wrapped around the bullet turned into a spinning water blade, churning incessantly, turning its brain into a pulp.

The beast's dying throes nearly destroyed the main control room into ruins, and when it finally fell, it crushed several low-level beasts. Ding Xuan stood up in severe pain and threw its body into the inventory.

Guo Yun staggered over: "Sister Ding, there is still a minute." ”

Ding Xuan didn't care about treating the wounds, and rushed to the entrance to the underground altar, the door was open, presumably the people in the organization took advantage of them to fight with the mermaids and hid below.

The two hurried down, and on the stairs they found a glowing reward chest, which was a surprise.

The top was turned upside down by strange beasts, but the bottom was so quiet that no sound could be heard.

There are five walls around the altar, each with a humanoid stick figure carved into it, according to the movie, which is a slut, a fool, a wise man, an athlete, and a virgin, representing the five young men who were sacrificed, and for each person killed, his blood filled the lines of the stick figure.

"Destroy these walls." Ding Xuan picked up the battle spirit axe and slashed at the wall, and Guo Yun also wore a finger tiger and smashed it with all his might.

Mission Complete: Take the elevator to leave.

The altar began to shake, huge stones fell from the top of the head, and an elevator suddenly appeared on the smashed wall, and the two rushed in, Delia also wanted to come in, but was cut off by an invisible wall, she knocked on the wall in despair, shouting Guo Yun's name, Guo Yun looked at her helplessly, and a trace of unbearability flashed in her eyes.

Ding Xuan closed the elevator with a hard heart, and the moment the elevator door closed, she saw a tall man in a pitch-black military uniform walking down the ladder down the altar, calmly looking at them in the rain of rocks, with an inquiring look in his eyes.

She didn't like that kind of look very much, as if she was being targeted by a poisonous snake, and her heart was cold. (To be continued......)
