The dense green forest sea in the distance, the waves are undulating, some slightly thinner trees have fallen one after another, the ground rumbles, as if there are thousands of troops galloping here, even if it is several kilometers away, you can hear the sound like thunder, countless mutant beasts are running wild in the jungle, and the sky is also occupied by mutant birds, dense, almost covering the entire sky.

As if sensing it, Luo Yuan suddenly looked at the area where the trunk of the Tianzhu Tree was located, and his pupils shrank suddenly.

I saw countless fountains with high temperature steam spewing out from there, rushing to a height of tens or even hundreds of meters, the number of fountains was several times higher than yesterday, and the eruption was more intense, more like the most hysterical eruption.

Wisps of green smoke rose from the bulging area.

As the ground continued to shake, the green smoke above became thicker and thicker, and the air gradually filled the air with a scorching smell.

"It's like the smell of sulfur when it's ignited?" Ning Xiaoran said uneasily, looking at the countless mutated creatures in the sky and the earth fleeing frantically, it seemed that something bad was about to happen.

"Brimstone?" Luo Yuan thought of this word and was stunned for a moment.

"How can there be a smell of sulfur here, is it a volcano!" The sudden thought in his heart made him unbelievable, but there was no other explanation than this.

At this moment, the Tianzhu Tree shook violently. Luo Yuan was shocked to find that the leaves that originally had an oily green luster had faded and completely lost their luster, and some of the leaves had even turned a little yellow.

"Don't be down!"

He was startled, came back to his senses, and shouted, "Get out of the shade of the trees, everyone run." ”

Everyone reacted and ran desperately, even at this juncture, Huo Dong and the others had no intention of throwing away the machine gun bullets, gritted their teeth, and tried to follow behind everyone. Wang Xiaguang's body has not yet recovered, and after running for a few hundred meters, he was the first to be unable to run, and gradually fell to the bottom.

Luo Yuan looked back at her sallow face, obviously unable to hold on, he ran back again, and before she refused, he directly put her on his back and continued to run forward.

Since she was completely disappointed in Luo Yuan that day, she cried almost all night, and the next day she secretly decided never to talk to Luo Yuan again, he has become extremely strange, and he is no longer the one in her impression, and even slept with two women openly in front of her.

But this posture of carrying people is so embarrassing, she was silent for a few minutes, feeling that her strength had recovered, and she couldn't help whispering anymore: "Let me down, I can run!" ”

"Don't make a fuss!" Luo Yuan slapped her ass hard.

Wang Xiaguang's body stiffened, and he didn't dare to move for a while.

After a few minutes, everyone finally ran out of the shade of the tree, holding their knees and panting desperately, and several people were even sitting on the ground and could not get up again. This kind of sprint-like running is the most physically exhausting, and most people can't run a kilometer at all, and being able to run for such a long time is already the level of ordinary long-distance runners before the end of the world.

Luo Yuan put Wang Xiaguang down, she disguised her hair and spread her hair, blushing and feverish, but no one paid attention to her expression at this time.

"Aurora, how can there be an aurora here?" Huang Jiahui shouted, her face shocked, only to see the white clouds in the sky scattered invisible, the wind and clouds changed, and from time to time flashed a few ethereal Ambilights, exuding a bewitching light.

"I'm afraid there's going to erupt here, and you can see the smoke is getting thicker and thicker over there." Lin Xiaoji pointed to the location of the root of the Tianzhu Tree and said with a pale face.

"Oh no, the mutant beasts are coming here." Huo Dong looked at the location of the isolation zone in fright, and was so frightened that he forgot to breathe for a while.

In the woods not far away, countless mutant beasts rushed towards this side like a tide, and several of them had already run onto the isolation zone. Luo Yuan's face was ugly, there were jungles on both sides of the highway, once the beast tide formed, it would bear the brunt here, and he couldn't hide from it no matter what.

"Go to the front post." Luo Yuan said loudly.

Under the threat of death, everyone's originally tired bodies once again gave birth to a force and ran desperately towards the outpost a hundred meters away.

However, the speed of the mutant beast was faster, a blue-level mutant beast flew past everyone, it was obviously frightened, with extreme horror in its eyes, even the nearby monitor lizard that was already dark blue level could not stop its footsteps, it continued to run towards the front after passing everyone.

There were more and more mutant beasts running over, and the ground was trampled and shaken, and several of them even crashed into the crowd in a daze, and Luo Yuan, who was cut off, was quickly killed, or was directly trampled by the monitor lizard.

A minute later, the crowd that was almost about to collapse finally arrived at the outpost, and Luo Yuan was already a little breathless. In just over a minute, there were almost more than ten dead in Luo Yuan's hands, and there was even a blue-level mutant beast among them, the intensity of its battle was far greater than what Luo Yuan had experienced before, if it weren't for his current physical strength, I am afraid he would have been exhausted by now.

Luo Yuan quickly checked it inside and killed a few colorful unknown strange insects that inhabited here.

On the second floor, except for one of the cannons, the barrel of which has been bent and unusable, the others are still well preserved, and even there are eight boxes of bullets, Luo Yuan glanced at it and said to several men: "Each of the three of you guards a gun hole, if you see a large mutant beast hitting you, shoot immediately, but pay attention to the consumption of bullets, don't finish the fight at once." Jiahui, you give them a deputy! ”

"Master Wang, your responsibility is the heaviest, pay attention to the small mutant creatures coming in through the gun's hole, don't be careless!" Luo Yuan said solemnly to Master Wang.

Master Wang nodded desperately, his body trembled, and his little hand was inserted into his trouser pocket and tightly grasped the sharp cone inside.

"Where are you going?" Huang Jiahui heard his voice and hurriedly asked worriedly.

"I'll go outside and take care of the defense of the last part of the house." Luo Yuan said solemnly.

At this time, it was meaningless to say anything, and Huang Jiahui's voice trembled a little: "You...... Be careful! ”

Luo Yuan nodded, glanced at everyone, and finally saw Wang Xiaguang's trembling and concerned gaze, he couldn't help but pause slightly, then turned around and walked down the stairs, silently reciting in his heart, "Sure!" ”

"Current Mission: D-Class Mission, Block the Impact of the Beast Tide, Mission Requirements: No More Than Two Deaths!"

D-level mission, this is a task level he has never encountered, if the E+ level represents the difficulty of killing a fourth-level mutant creature, that is, the dark blue level, then the D-level obviously represents the difficulty of killing a fifth-level mutant creature. So far, he hadn't really seen a fifth-level mutant beast, but he had felt its terrifying momentum from a distance, and just that had already made him tremble and his scalp tingle.

Of course, at that time, his strength was far from being so strong, but even now, he was still not sure at all, his current strength could barely kill a fourth-level mutant beast, but if he wanted to kill a fifth-level mutant beast, it was simply impossible.

It's like the blue level that he used to think was extremely powerful, and now he can't kill it effortlessly. A fifth-level mutant beast could also easily kill him. The difference between one level and the strength is very different, as if separated by a deep chasm.

Of course, there is a great possibility that there will be no level 5 mutant beasts in this mission, but its difficulty is the same, and there is no difference in substance.

Luo Yuan walked outside, and at this time, more and more mutant beasts had rushed through the isolation zone and rushed towards the highway.

He quickly opened the attribute panel, and added all the five skill points left from the last upgrade to the knife technique, a large amount of information frantically poured into his mind, he closed his eyes, and felt this sudden memory, a powerful aura gradually spread from his body, and the air became restless.

There seems to be an invisible force field, filling the nearby area, and as time passes, some small gravel beats slightly, and then the frequency of the beating becomes faster and faster, as if it is about to levitate. Several low-level mutant beasts that had just run into this area, as if they had been struck by lightning, fell to the ground stiffly, convulsed constantly, and it didn't take long for them to be silent.

Even the monitor lizard snorted a little uneasily, the scales all over his body stood up one by one, and when he looked at Luo Yuan, a trace of fear flashed in his eyes.

Knife Mastery: 19

It is also only one step away from a higher level.

He slowly opened his eyes, and as he finished his understanding, the momentum around his body quickly weakened, and the beating gravel near him also subsided, and a trace of regret appeared on his face.

"After all, it's not the strength that you have cultivated by your own hard work, and it's always separated from the memories transmitted by the system." He secretly said in his heart: "Theoretically, the strength of 'Sword Mastery: 19', he can only fully exert the strength of 'Sword Mastery: 15' at most. ”

But even so, his current strength has increased a lot. The application of the knife is more handy, and even the condensation of the will has gone one step further, he pulled out the chopping knife, only to see a trace of brilliance on the knife instantly, the knife is extremely stable, and there is no such thing as a flame as violently swallowing before, it is now like a quiet spring, cold with a sharp cold light. It even has a material texture.

At this time, the characteristic tearing sound of the cannon rang out.

A blue-level mutant beast on the left instantly splashed with blood, and after more than ten seconds, its entire body was smashed and fell to the ground like a rag bag, and the bullet continued to wreak havoc on the corpse for a few seconds before it stopped.

This group of people had never operated such a weapon before, and under the mental tension, they were slow to react, and they couldn't stop at all when they pressed the button. If this continues, I'm afraid it won't be long before the bullets run out.

Luo Yuan's brows furrowed, and his face gradually became solemn.

Countless creatures, emerging from the trees, rushed towards this place in groups. There were also two huge dark blue-level creatures mixed in, but at this moment, they were crowded with low-level mutant beasts, running for their lives.
