The place where Gao Feng was located was the living area, which was also the second floor of the base. For the time being, those underground races like lizardmen couldn't reach this place.

Of course, it wasn't completely safe either. In Gao Feng's memory, some green dwarves would climb down through the ventilation ducts. These green dwarves looked tiny, but they were extremely dangerous to ordinary people.

Gao Feng took his sword and went out. There were already quite a number of people in the corridor. Most of them were men and women in pajamas, discussing what had happened.

At this time, no one had really realized the danger yet. Although they were a bit curious, they all looked quite relaxed.

Seeing Gao Feng running out with a sword in his hand, a bald middle-aged man with a big belly joked, "Hey, Xiao Feng, are you going to save the world? Hahaha..."

This somewhat boring joke had a good effect. The men and women in the corridor all laughed along.

There was no malice in this laughter. They just really thought it was funny. In their eyes, Gao Feng, who was only seventeen years old, was still a child.

A child, without knowing what had happened, ran out seriously with a sword in his hand. To them, it was rather comical.

Gao Feng didn't have time to argue. He just shouted, "The green dwarves are coming. Everyone, get ready quickly."

Hearing the words "green dwarves", the bald middle-aged man who had been joking with Gao Feng had his smile freeze for a moment. After a pause, he scolded, "What do you, a child, know? Don't joke about such things."

As normal people, when they heard unpleasant news, their first reaction was disbelief. Especially when this news came from a child. The middle-aged man's scolding was almost instinctive. He wanted to deny the bad news Gao Feng had said by such a denial.

Gao Feng had neither prestige nor evidence. Of course, it was impossible for him to make others believe him in a short time. And he had no intention of getting entangled with these people. He had more important things to do.

Gao Feng just glanced at the bald man and ran past him.

The bald middle-aged man, however, felt insulted. When Gao Feng passed by him, he grabbed Gao Feng's clothes. "Kid, it's so impolite to just run away like this..."

Gao Feng didn't expect the bald man to pull him. His face immediately darkened. He turned his head and gave the bald man a cold look. His eyes were black, bright, sharp, and had a cold and sharp edge like a blade. The bald man couldn't help but feel a chill in his heart and involuntarily let go of his hand.

The pull and the release happened very quickly, but it made Gao Feng's steps pause involuntarily.

The bald middle-aged man was startled by Gao Feng's cold eyes. Feeling that he had lost face in front of everyone, he was about to grab Gao Feng again to argue with him when he saw Gao Feng suddenly jump up and draw his sword out of its sheath. The sharp blade as bright as autumn water turned into a cold light and slashed over.

Although Gao Feng's sword strike couldn't be said to be exquisite, it was real military swordsmanship. It was fast, simple, fierce, and effective.

"Ah..." The bald middle-aged man didn't expect Gao Feng to be so crazy. He was so frightened that his heart almost stopped beating, and he screamed out in shock.

"Puff..."

The sharp blade cut through the air and chopped a green figure that had just jumped down from the vent into two pieces. The splattered green blood sprayed all over the bald middle-aged man's face and body.

The green dwarves were no more than one meter tall and looked like children of seven or eight years old in terms of body shape. However, their skin was as rough as that of a toad, with a pointed and thin head and a skinny body.

Although it was chopped into two pieces by Gao Feng's sword, it didn't die immediately. The two halves of its body were still twitching on the ground. In its big green eyes without eyelids, there was a vicious and chilling light. It was also making shrill and strange cries of "Wua Wua", which was quite visually shocking.

Gao Feng took a look at the killed green dwarf. It should have been very uncomfortable for him to kill a humanoid race for the first time. Perhaps because he had experienced too much killing in his memory, Gao Feng was surprisingly calm and composed.

This instinctive sword strike without thinking surpassed Gao Feng's peak level. Once the sword was drawn, it was as if he had practiced it thousands of times, so skillful and natural without any clumsiness.

In his memory, Gao Feng's Broken Blade Swordsmanship had reached level 20. His attainment in this swordsmanship was unparalleled in the world. Unconsciously, everything in his memory had merged with reality.

Gao Feng didn't have time to reminisce. After carefully looking at the green dwarf and confirming that it was the same as the creature in his memory, Gao Feng shouted to the others, "The monsters from underground have attacked. Everyone, hurry to the shelter to hide..."

The corpse of the green dwarf on the ground also woke everyone up like a dream. Many women screamed one after another.

There were also a few men who could still keep calm. But their looks at Gao Feng had also changed. Among them, a security guard's eyes showed a strange light. Gao Feng's sword strike was clearly the Broken Blade Swordsmanship of the Guangming Empire's military swordsmanship.

He had been a soldier before and had practiced the Broken Blade Swordsmanship for almost twenty years. But Gao Feng's swordsmanship was so skillful and experienced that it seemed to be even better than his. How could Liu Jun not be curious and astonished?

The sudden appearance of the green dwarves not only verified Gao Feng's words but also showed his skillful and superb swordsmanship as well as his extraordinary calmness and maturity.

Everyone usually lived together and was quite familiar with Gao Feng. But today's Gao Feng made everyone feel strange. There was even an awe-inspiring aura about him.

Gao Feng quickly gave an instruction and then ran out along the corridor at a fast pace.

After Gao Feng's figure disappeared, the people in the corridor still hadn't fully come to their senses. The sudden appearance of the underground monsters in the base was far beyond their imagination, and they couldn't accept this reality in a short time.

"Don't just stand there, everyone. Take the children and go to the shelter in Area F. That's the safe place." The former soldier shouted loudly. After all, he had been a soldier before and was a member of the security team, so he was much calmer than these ordinary employees in a critical moment.

With this reminder again, everyone suddenly realized what to do. They hurriedly ran back to their rooms, put on clothes, picked up their still-sleeping children, packed up valuable items. After a chaotic rush, everyone anxiously rushed towards the third floor.

To deal with emergencies, the base held a drill once a year. Although everyone was panicked, they hadn't encountered the enemy yet, so they could still barely keep calm and act according to the steps of the drill.

The second floor of the base was a huge living area with a vast area. It was divided into nine areas according to the work level. Thanks to his uncle's influence, Gao Feng also got a separate room in Area E. And his uncle's whole family lived in Area C. Sisi's father was a top leader of the base and lived in Area B.

If you come across this story on Amazon, be aware that it has been stolen from Royal Road. Please report it.

Gao Feng had to find his uncle first to remind him to be careful. Then he had to find Sisi. Through Sisi, he could find her father, Wen Anyang. Wen Anyang was the executive president and also the most powerful person in the base.

If he could persuade Wen Shian, saving the base wouldn't be just a dream.

The increasingly fierce battles underground had already awakened everyone. The roads were full of people with panicked expressions, and most of them were at a loss.

Since the base was built, the mining had been going very smoothly. Although there had been many conflicts with the underground races, those battles were all handled by the security team. In everyone's eyes, those underground races were just savage beasts. Although they were fierce, they weren't that scary. After all, there was a huge gap in civilization between the two sides.

When the underground races launched a full-scale attack, no one had realized the seriousness of the situation yet. Due to the destruction of the communication optical brain system, the communication within the base was almost completely interrupted. It could be said that neither the base's top management nor the security team in the battle knew the current situation better than Gao Feng.

The situation was urgent. Gao Feng knew that if he shouted that the enemies were coming at this time, it would only attract a lot of questioning from others. He didn't have the time or energy to deal with these, so he could only speed up and head towards Area C.

He quickly ran across the intersection and turned left into Area C. There were four-story high-rise buildings here, with spacious spaces and bright windows. Under the huge photon-simulated sky curtain on the top, one couldn't feel the depression and stuffiness underground at all.

When entering through the gate, the scanner beeped, and a gentle electronic synthesized female voice said, "The visitor has access rights, but is holding a sword, which is a dangerous weapon. Please accept the inquiry."

Gao Feng didn't have time to pay attention to this. He just ran straight towards Building C7 where his uncle lived, leaving only the sharp howling of the electronic alarm behind.

At this time, the people in Area C were also awakened. Many of them were looking out through the windows to check the situation. There were also quite a number of people on the clean streets. Seeing Gao Feng in a hurry and carrying a long sword, everyone's eyes looked a bit strange.

As soon as Gao Feng arrived at the downstairs of Building C7, he was stopped by two middle-aged men. One of them asked seriously, "Whose child are you? What are you doing with a sword?"

The middle-aged man frowned deliberately to look imposing, with a look of scrutiny in his eyes. His condescending questioning tone showed a sense of superiority.

Gao Feng said impatiently, "The underground races are coming up to kill. If I were you, I'd quickly pack up things and go to the shelter."

The middle-aged man wanted to ask more questions, but Gao Feng had already flashed up the stairs. The middle-aged man said angrily, "Whose wild child is this! Talking nonsense..."

The other man thought for a moment and said, "It seems to be Gao Tong's nephew."

The middle-aged man was still very indignant. "How did Old Gao educate his child? Really..." Before he could finish his words, he heard a series of terrified howls. On the other side of the street, seven or eight people were screaming and running over. Behind them, several ugly green monsters were chasing after them vigorously.

A green dwarf suddenly jumped up and landed on a fat woman who was lagging behind. Its claws were as sharp as knives and quickly scratched at the fat woman's face and body.

After the fat woman let out two miserable howls, she fell to the ground with her flesh torn and bloodied and soon died.

Seeing this scene, everyone was startled. The people living in this area were all high-level staff of the base and lived a comfortable life. Although it was an era when everyone practiced martial arts, most of them had no real combat experience. Let alone these people. Including the two middle-aged men, everyone screamed and scattered to run away.

In fact, there were only seven or eight green dwarves rushing over. If everyone could respond calmly, these little monsters wouldn't be that powerful.

Gao Feng didn't see this scene. He had already rushed to the fourth floor. "Bang Bang Bang..." Time was tight, so Gao Feng knocked on the door vigorously.

The solid wooden door glowed and a virtual screen appeared, showing the image of a beautiful woman with a high bun. "What are you here for?" The beautiful woman raised her slender eyebrows and asked impatiently.

This woman was Gao Feng's aunt, Lin Fei. She had always been mean and sharp-tongued and looked down on Gao Feng, always thinking that he was a huge burden.

If it weren't for Lin Fei's character, Gao Feng wouldn't have moved out to live by himself. Usually, if there was nothing wrong, Gao Feng would never come to her door.

"There's something urgent. Where's uncle?" Gao Feng asked directly because of the urgency.

Lin Fei's face changed slightly. She thought Gao Feng was really rude and was about to scold him when she saw a cold light flash in Gao Feng's black and bright eyes, as if an invisible sword blade stabbed into her heart. Although there was a door between them, Lin Fei was still startled and quickly replied, "Your uncle is on duty."

Gao Feng sighed. His luck was really bad. But his uncle was in the duty room, where the security was very strict, so there was no need to worry about his safety for the time being.

"You and Jiaojiao should come out quickly and go to the shelter." Gao Feng said in an almost commanding tone.

Aunt Lin Fei was unwilling. "Why should we go to the shelter? We'll just stay at home." She usually didn't like Gao Feng, and she had just been startled by him. Naturally, she wouldn't listen.

Gao Feng had over a hundred years of rich experience. He guessed Lin Fei's thoughts at once. With prejudice in her heart, she couldn't be persuaded by just a few words. If it were normal times, Gao Feng could think of several ways, but now time was extremely tight, and he didn't have the time.

Taking two steps back, Gao Feng drew his sword out of its sheath, took a deep breath, and struck with his sword.

Lin Fei in the room saw Gao Feng draw his sword and screamed in fright, "You're crazy, Gao Feng!" Before she could finish her sentence, she saw two sword lights, one horizontal and one vertical, on the light screen, crossing into a cross, cold and shining.

It was the killing move "Breaking Mountain Slash" in the Broken Blade Swordsmanship. However, the "Breaking Mountain Slash" was usually a single quick slash, but Gao Feng used a continuous cross-shaped slash. If someone who was familiar with this swordsmanship saw it, their eyes would surely pop out.

Only a master with a swordsmanship level above level 10 could master this technique. Ordinary people couldn't reach this level even if they practiced hard all their lives.

Although the solid wooden door was thick, it was still made of wood after all. Gao Feng's Si Feng Sword wasn't a famous sword, but it was made of a high-strength alloy named Xuan Tie in modern times. It was extremely sharp and tough. It could be said to be the peak work of human cold weapon casting.

"Cutting through iron like cutting through mud" was a true portrayal of the Si Feng Sword, not an exaggeration.

With Gao Feng's skillful swordsmanship, there were several cross-shaped sword marks on the wooden door. Gao Feng admired the straight and regular cross-shaped sword marks for a while. He was quite satisfied that he could use this sword technique with his current strength.

Kicking open the door, with the flying wood chips, Gao Feng rushed in like this.

"Don't move." Lin Fei was holding a laser pistol, pointing at Gao Feng nervously and shouting. Hearing the chaos outside, Lin Fei was scared, so she took the gun to boost her courage. She didn't expect Gao Feng to break in so forcefully. In a panic, she quickly raised the gun to defend herself.

Although Lin Fei was mean, she was still a woman after all and had never done such a thing before. Her hand holding the gun was trembling. Seeing this, Gao Feng was a bit nervous. A novice like her holding a gun was very likely to fire accidentally.

Almost without thinking, Gao Feng dodged and swung the Si Feng Sword horizontally at Lin Fei's wrist. With great force, he knocked the gun flying. Lin Fei wanted to scream again, but Gao Feng took the opportunity to chop her on the neck with the side of his hand and knocked her out immediately.

"Trouble..." Gao Feng muttered, picked up the laser pistol. Although it was fingerprint-locked, it was still a long-range weapon, wasn't it?

"Brother, are you going to kill Mom?" Thirteen-year-old Jiaojiao asked curiously. Jiaojiao was hiding behind Lin Fei and saw Gao Feng knock Lin Fei down with her own eyes, which also startled her. However, she completely inherited her uncle's carefree personality and wasn't panicked at all. Instead, she was a bit curious.

"No. I'm playing a game with Auntie." Gao Feng carried Lin Fei on his shoulder and dragged Jiaojiao's hand and walked out.

Jiaojiao pouted and said disdainfully, "Come on, you're lying to ghosts. I know you dislike Mom the most."

Gao Feng said with a serious face, "Don't talk nonsense, or I'll deal with you too."

Jiaojiao looked at Gao Feng pitifully and said, "Brother, I've been so nice to you. I left half of my chocolate for you. I even introduced pretty female classmates to you as girlfriends. Don't you remember?"

Gao Feng's face darkened. This naughty kid. "Don't talk about this. There's a big thing going on now. You have to be obedient..." Gao Feng earnestly instructed her.

Although Lin Fei was relatively slim, she still weighed over a hundred pounds. Carrying such a grown-up person, Gao Feng was definitely not relaxed. After going downstairs in one breath, the street was already empty.

Gao Feng immediately saw the dead woman and his eyes narrowed. There were more and more monsters underground, and his time was running out.

Holding Jiaojiao's hand, he quickly ran towards the shelter. When the shelter was established, considering emergency situations, three shelters were built in total. The one closest to Area C was located underground in a huge commercial activity center in Area D.

Just after leaving Area C, a group of people came running towards them. Behind them, more than a dozen green dwarves were chasing after them, squeaking and shouting excitedly.

"Damn it, such bad luck..." Gao Feng said gloomily and walked towards them.

When everyone was running away in a panic, Gao Feng, who was carrying a woman and holding a girl's hand, went against the trend. Even in this chaotic moment, he attracted a lot of attention.

"Is this kid crazy?" This was also the first reaction of many people.
