"No, three C-grade crystal nuclei are enough" Liu Xin's words had not yet fallen, and the cold voice of the system sounded again.

"Ding, main quest 7, the request of the four holy beasts, help the four holy beasts to solve the fish that slipped through the net, a total of 10 waves, the current wave 0, the next wave of attack time, 3 hours later, the attacking enemy is led by 1 B-level creature, and several other creatures. The mission must block all enemies, and a wave of omissions will result in the mission failing. If you fail, the main quest will be interrupted, and the quest will reward the skill army of the undead. ”

"Coming?" Liu Xin looked up at the sky and muttered to himself.

"What's coming?" Han Chao couldn't understand why he couldn't hear it, so he asked directly.

"Give me the crystal nucleus." Liu Xin didn't explain, and directly stretched out his hand to ask Han Chao for the crystal nucleus.

The bald head quickly found the C-grade crystal nucleus that Liu Xin wanted from the pile of crystal nuclei, and handed it over respectfully, Liu Xin was not polite, and after taking it, he didn't care about the excited two, he turned around and walked towards the door.

"Oh, by the way, inform those leaders that the first wave of aliens will arrive in three hours, and if you want to see it, you can turn on the satellites to see it, and I will allow you to watch the battle and take a good look at what the aliens are like, but remember, whoever dares to let go of the black hand will wait for me to find him." Liu Xin, who had just arrived at the door, turned his head directly and looked at Han Chao and said.

"What? Aliens are coming at this time? It's at least a year before they arrive, is the future nearly changing? When Han Chao heard Liu Xin's words, his eyes widened directly, and he thought incredibly.

Liu Xin didn't explain much, he went out and left, three hours is not long, he not only has to find a place, but also learn skills to recover his strength.

"Quick, inform the leaders." Han Chao shouted a command at the bald head, and he himself rushed towards the research institute quickly.

Regardless of whether Han Chao did what he said or not, after Liu Xin left, he quickly absorbed the crystal nucleus, got two from Wang Ling's vault, and Han Chao changed to three more subjects, a total of 5 C-level crystal nuclei, enough to learn skills.

"Ding, the host gets two points of level 4 energy and 500 points of level 3 energy, I hope the host will continue to work hard." The rhapsodic mechanical voice sounded in Liu Xin's mind.

"Rhapsody, what are the specific coordinates of the alien invasion?" Liu Xin can be regarded as a rich man now, and he directly asked about the specific location of the aliens.

"After deducting 100 points of third-level energy, the specific coordinates of the appearance of aliens are XXX, which has been specifically marked on the map."

Liu Xin quickly opened the map, saw a conspicuous red dot in it, and thought: "It's not bad, it's in country C, you don't need to go far." ”

Liu Xin, who put away the map, quickly flew towards the designated location, and the sonic boom formed by the high-speed movement directly shook the hearts of all the creatures along the way, and even some bold creatures quietly followed behind Liu Xin, trying to find out.

Soon Liu Xin came to a grassland, where waist-high weeds grew, and some herbivorous mutated creatures roamed the grassland, eating those tender green seedlings, and predators were also hiding in it, ready to ambush the herbivore.

It seems to be a harmonious grassland, but it hides a deadly killing machine, and if you don't pay attention, maybe the next one to become food is you.

"Hah!" Liu Xin let out an angry roar, accompanied by a powerful qi that spread rapidly to the surroundings.

A gust of wind spread out from Liu Xin's position in all directions, suppressing the weeds one by one.

All kinds of mutated creatures quickly ran in all directions, they could feel the powerful momentum and endless smell of blood in the wind, Liu Xin killed a whole 100 million zombies in the experience dungeon, and that bloody qi could make ordinary people directly break down.

The intelligence of these mutated creatures is not as high as that of humans, but their intuition of danger is much stronger than that of humans, they can feel the danger coming from Liu Xin's body, if they stay, they may be the next to die, so they did not hesitate to escape.

After clearing the field, Liu Xin directly took out the bread and began to recover in situ.

Time passed minute by minute, and a lot of creatures also appeared on the periphery of the grassland, all of them were attracted by Liu Xin's movement just now, including human beings and some powerful mutant creatures. When they saw Liu Xin, they knew that something big was going to happen, and most of them quietly followed Liu Xin, wanting to see what was going on.

Liu Xin didn't care if they wanted to watch the battle or not, it was not bad to let them see, at least let them know that now was not the time for infighting, and the real enemy was aliens from space.

Liu Xin, who was still closing his eyes and recuperating, suddenly opened his eyes and looked at a mountain depression in the distance.

There, Liu Xin felt the fluctuations of space, as if a subsidiary world was about to appear. The calm space used to be as smooth as a mirror like the surface of a lake, but now, like a stone thrown into it, it directly caused ripples to appear in the entire space.

Liu Xin pulled out the cracked sword of the Brotherhood, and looked at the spatial node that began to enlarge with waiting. Whether it is looking at Liu Xin's creatures at the scene, or the leaders who are observing through the satellite, and looking at the ever-expanding space nodes, they all jump with excitement, everyone knows that the appearance of each space node represents an endless treasure, and even among the mutant creatures, there are legends about the world behind the space nodes.

All the creatures on the scene are in an attack posture in an instant, as long as the node expands to a certain extent, they will rush forward without hesitation, this is an opportunity to become a strong one.

Unfortunately, they don't know that behind the node are aliens full of desire to conquer and destroy, not the subordinate world they are familiar with.

When the node was enlarged to about half a meter in diameter, a gray palm covered with mucus stretched out from the node, and there were only three thick fingers on the entire palm, each finger was the thickness of most of a normal person's fist, and the entire palm could be comparable to most of the body of a normal human.

The whole palm of the hand is like an enlarged frog's foot, and anything that looks cute is magnified thousands of times and makes people shudder to look at it.

All the creatures that were ready to sprint widened their eyes at this moment, and rushed out of the creatures that appeared in the space node for the first time, this was the first time it happened, and all the creatures stopped cautiously and quietly looked at the huge arms that kept squeezing out.

Liu Xin didn't move, from the qi sensing technique, he saw that the owner of that arm was just a D-class creature, that is, it looked more infiltrating, and the ability to ignore the destruction of space could enter Liu Xin's eyes, and it couldn't pose any threat to Liu Xin.

The frog didn't burrow out entirely, but once again stretched out an arm and pinched the edge of the spatial node.

One, two, and three frogs stretched out from the spatial node, pinching the edge of the spatial node.

After pinching the space node with one arm, he began to exert force, pulling the space node and began to spread in all directions, and the expansion speed of the entire node increased by several notches in an instant.

Liu Xin looked at the rapidly expanding space node, directly took out the wrath of the stars in the empty ring, and pulled the bowstring.

"Damn, who is this madman? Doesn't he know that every spatial node is an endless treasure? If you want to destroy him, go and stop him. ”

"Kill him, the treasure is ours."

"Ah, the opportunity to become a strong man is right in front of you."

A roar of rage sounded in the distance, followed by a series of figures.

"Damn it, these idiots! I really shouldn't have wanted them to know about aliens, and I was stabbed now, Mom. Liu Xin looked at the rushing figures angrily, and his anger soared in an instant.

"Get out of here!" Liu Xin's hand did not stop, and he let out a counterattack roar, and all the figures that rushed up were pushed far away in an instant, and the arrows that had been condensed in his hand also rushed straight into the space node at this time.

"Poof!" A tuft of blue blood gushed out down the node, followed by an angry roar.

"Damn, this madman has angered the other party, everyone go up together and kill him!"

"My treasures, all mine."

"Kill this idiot, kill!"

With the roar coming from the node, all the people who were pushed away were angry, and they frantically waved their weapons and rushed towards Liu Xin again.

"Mom, these idiots, I'll solve you first." Liu Xin looked at the figure that rushed again, and directly pulled out the sword of the Brotherhood inserted in front of him, and swept through, and the fastest figures were directly extended by the sword rays, even if he did not transform, Liu Xin was also a person in the C rank, and it was an overwhelming force for these cannon fodder.

A large number of figures were divided into two in an instant, the blood in the sky was splashing, and the figures who did not die looked at their severed lower bodies in fear and unwillingly, and Liu Xin's blow directly cut nearly thirty people.

Looking at the constantly struggling figure on the ground, Liu Xin's anger was even worse, these people who rushed up were all humans, and all the mutated creatures were just watching from a distance, and they didn't move at all.

"Grass, this is the inferior root of human beings" Liu Xin looked at those dying human beings, and thought angrily, this is the anger of the same race, the anger of the entire human race.

At this time, a fist-sized ball flew out of the spatial node, and a gust of pale green gas emerged from the ball, filling the area of several hundred meters around the node.

The wounded who were still struggling on the ground, after inhaling the pale green gas, began to change rapidly, their skin began to turn white, and their eyes began to roll up, revealing the white of their eyes.

"This is a zombie?!" Someone looked at the half of the corpse on the ground that was thinking about Liu Xin's constant crawling in horror, and said tremblingly.

All the survivors retreated quickly at this moment, although most of the zombies were wiped out, but the disaster at the beginning of the apocalypse left a deep shadow in everyone's hearts.

"It's all them! They all made it" Someone did it in horror, apparently the reappearance of the zombie and the initial appearance of the creature behind it directly caused his mental breakdown.
