The dense green forest in the distance was undulating, with some slightly thin trees falling down, and the ground rumbling, as if thousands of troops were galloping. Even if it was several kilometers away, you could hear the sound of thunder. Countless mutant beasts were running wildly in the jungle, and the sky was also occupied by mutant birds, densely packed, almost covering the entire sky.

As if it was sensing, Luo Yuan suddenly looked at the Tianzhu tree in the area where he was located, and his pupils suddenly shrank.

I saw countless fountains emitting high temperature steam erupting from there, rushing to a height of dozens of meters or even hundreds of meters. The number of fountains was several times higher than yesterday, and the eruption was even more intense, more like the last hysterical outbreak.

Widths of blue smoke rose from the raised area.

As the ground continued to shake, the blue smoke on it became thicker and thicker, and the air gradually filled with a burnt smell.

"This seems to be the smell of ignition of sulfur?" Ning Xiaoran said uneasy, watching countless mutant creatures in the sky and underground fleeing wildly, as if something bad was about to happen.

"Sulphur?" Luo Yuan was stunned for a moment when he thought of this word.

"How could there be a smell of sulfur here? Is it a volcano?" The sudden thought in his mind was so unbelievable, but there was no other explanation except this.

At this moment, the Tianzhu Tree shook violently. Luo Yuan was shocked to find that the leaves that were originally with a green luster were dim and colored, completely lost their luster, and some of them were even a little yellow.

"Don't fall down."

He was shocked, suddenly came to his senses, and shouted loudly: "Leave the shade here quickly, everyone will run away."

Everyone reacted and ran desperately. Even at this moment, Huo Dong and others had no intention of throwing away the machine cannon bullets. They gritted their teeth and tried to follow everyone. Before Wang Xiaguang's body recovered, he ran for hundreds of meters and could not run first and gradually fell to the end.

Luo Yuan turned around and looked at her waxy face, obviously unable to hold on. He ran back again. Before she could refuse, he directly resisted her and continued to run forward.

Since she was completely disappointed with Luo Yuan that day, she cried for almost all night. The next day she secretly decided not to talk to Luo Yuan again. He had become extremely strange and no longer the one he remembered. He even slept with two women openly in front of her.

But this back-to-human posture was so shameful. She was silent for a few minutes, and felt that her physical strength had recovered, so she couldn't help but whisper: "Let me down quickly, I can run away."

"Don't make trouble" Luo Yuan slapped her butt hard.

Wang Xiaguang's body stiffened and he didn't dare to move.

A few minutes later, everyone finally ran out of the shade of the tree, holding their knees and gasping desperately. Several people were even sitting on the ground and could no longer get up. This kind of sprint-like running consumed the most physical strength. Most people could run less than a kilometer. Before the end of the world, they were already at the level of ordinary long-distance runners.

Luo Yuan put down Wang Xiaguang, and she concealedly pulled her hair, blushing and having a fever, but no one paid attention to her expression at this time.

"Aurora, how can there be aurora here?" Huang Jiahui shouted, with a shock on her face. She saw the white clouds gathering and dispersing invisible, and the wind and clouds changed. From time to time, a few ethereal and uncertain streams of light flashed over and over, emitting a charming light.

"I'm afraid a volcano erupts here. Look at the thick smoke over there getting thicker and thicker." Lin Xiaoji pointed to the location of the roots of the Tianzhu tree and said with a pale face.

"No, the mutant beast is coming here soon." Huo Dong looked at the location of the isolation belt in fear, so scared that he even forgot to breathe for a moment.

In the woods not far away, countless mutant beasts rushed towards this side like tides, and several of them had already run into the isolation zone. Luo Yuan looked ugly, and there were jungles on both sides of the expressway. Once the beast tide was formed, the place would be the first to be affected and could not hide no matter what.

"Go to the outpost in front." Luo Yuan shouted loudly.

Under the threat of death, the originally tired bodies of everyone developed a force again and ran towards the outpost a hundred meters away.

However, the mutant beast was faster. A blue-level mutant beast quickly passed by everyone. It was obviously scared, with extreme horror in its eyes. Even the giant lizard nearby could not stop it. After passing by everyone, it continued to run forward.

More and more mutant beasts were running over, and the ground was stomped and vibrated. Several of them even rushed into the crowd. Luo Yuan, who was broken behind, quickly killed or directly stomped by the giant lizard.

A minute later, the people who were almost about to collapse finally arrived at the outpost, and Luo Yuan was already breathing a little. In just over a minute, there were almost more than ten people who died in Luo Yuan's hands, and there was even a blue-level mutant beast. The intensity of the battle was far greater than what Luo Yuan had experienced before. If it weren't for his significant increase in physical strength, he would have been exhausted now.

Luo Yuan quickly checked inside and killed several colorful unknown monsters living here.

On the second floor, except for one of the gun barrels that were bent and unusable, the rest of the cannons were well preserved, and even the bullets had eight boxes. Luo Yuan glanced at them and said to several men: "Each of you three guards a gun hole. If you see a large mutant beast hitting, shoot immediately, but be careful about the consumption of bullets and don't finish it all at once. Jiahui, you can kill them with the deputy."

"Wang Shishi, you have the most responsibility. Pay attention to small mutant creatures coming in through the gun hole. Don't be careless," Luo Yuan said to Wang Shishi seriously.

Wang Shishi nodded desperately, her body trembled constantly, and her little hand inserted into her pants pocket and grabbed the pointed cone inside.

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

"I'll go outside and be responsible for the final defense here." Luo Yuan said solemnly.

Nothing is meaningless at this time, Huang Jiahui's voice trembled: "You... Be careful

Luo Yuan nodded, glanced at everyone, and finally saw Wang Xiaguang's heart-shaking and concerned gaze. He couldn't help but pause slightly, then turned around and walked down the stairs, silently saying "Confirm" in his heart.

"Current mission: B-level mission, blocking the impact of the beast tide, mission requirements: The number of deaths shall not exceed two people"

Level B mission, he has never encountered a mission level. If Level F represents the difficulty of killing a level 4 mutant creature, that is, the deep blue level, then Level B obviously represents the difficulty of killing a level 5 mutant creature. So far, he has never really seen a level 5 mutant beast, but has felt its terrifying momentum from afar. Just this has already made him frightened and his scalp numb.

Of course, at that time, his strength was far from that strong, but even now, he was still unsure at all. His current strength could barely kill a level 4 mutant beast, but it was impossible to kill a level 5 mutant beast.

Just like the blue-level that he used to think was extremely powerful, and now he can't kill him effortlessly. Level 5 mutant beasts can also easily kill him. The difference between level 1 and level 1 is very different, just like a deep gap.

Of course, there is a great possibility that this mission will not have a level 5 mutant beast, but its difficulty is the same, and there is no difference in essence.

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

He quickly opened the attribute panel and added all the five skill points left in the last upgrade to the sword technique. A large amount of information rushed into his mind. He closed his eyes and felt the sudden appearance of the memory. The powerful aura gradually spread out from him, and the air became restless.

There seemed to be an invisible force field that filled the nearby areas. As time went by, some tiny gravel jumped slightly, and then the frequency of jumping became faster and faster, as if it was about to levitate. Several low-level mutant beasts that had just run into this area seemed to be hit by lightning, fell stiffly to the ground, twitching constantly, and soon there was no sound.

Even the giant lizard sniffed a little uneasy, and its scales stood up one by one. When he looked at Luo Yuan, a trace of fear flashed in his eyes.

Sword mastery: 19

It's only one step away from a higher level.

He slowly opened his eyes, and as he finished his perception, the momentum around him weakened rapidly, and the beating gravel nearby calmed down, and a hint of regret appeared on his face.

"After all, the strength that is not achieved through one's own hard work is always separated from the memory transmitted from the system." He said in his heart: "Theory, 'Sword Mastery: 19, Strength, he can only fully exert his strength at most 'Sword Mastery: 15, Strength."

But even so, his current strength has increased a lot. He is more comfortable in applying the sword light, and even the condensation of will has become one step further. He pulled out the sword and saw a ray of light lit up on the sword instantly. The sword light is extremely stable, and there is no phenomenon of violent exhalation like a flame before. It is now like a quiet clear spring, with a sharp cold light in the coldness. It even has a material texture.

At this time, the unique sound of tearing the cannon started to sound.

A blue-level mutant beast on the left instantly splashed blood. After more than ten seconds, his entire body was smashed and fell heavily to the ground like a rag bag. The bullets continued to rage on the corpse for a few seconds before stopping.

This group of people had never manipulated such a weapon, and was nervous and slow to react. They could not stop when they pressed the button. If this continues, it will probably not take long before the bullet will be gone.

Luo Yuan frowned and his face gradually became solemn.
