End of the World: Copy 23 trillion gold at the beginning

As Lin Feng and his companions went deeper, they came to the teaching building. Various hand-painted warning signs were posted on the walls, revealing a tense atmosphere everywhere.

The guard then took them to an office, knocked gently on the door, and opened it only after receiving a response.

Inside the house, an old man with gray hair and glasses was standing in front of the window. He slowly turned around after hearing the noise.

"Professor Liu, they are the ones who are looking for you."

After the guard finished speaking, he closed the door and stood aside.

"Who are you? Where are you from?" Professor Liu asked, staring at Lin Feng with a sharp gaze.

Lin Feng raised the corner of his mouth, but did not answer directly. Instead, he took out a pack of cigarettes from his pocket, took out a cigarette from the box and handed it over.

"Professor Liu, do you smoke?"

When Professor Liu saw the cigarette in Lin Feng's hand, his pupils suddenly shrank, but he quickly regained his composure and said:

"No, I haven't smoked in almost ten years, ever since that disaster."

"It's okay. If you really want to smoke, I'll take care of your cigarettes from now on."

"You kid, you're quite arrogant." Upon hearing what Lin Feng said, Professor Liu actually smiled and took the cigarette from Lin Feng's hand, looked at the words on it, and said, "Lotus, I don't think I've ever heard of this brand of cigarettes before the disaster."

You hadn't heard of it at the time, this is the cigarette on our planet, it would be strange if you had heard of it.

Lin Feng thought to himself, but said, "It doesn't matter whether you've heard of it or not. The most important thing is that it tastes good. How about I light it up for you?"

Professor Liu held the cigarette between his fingers, looking away from the cigarette box, and reassessing Lin Feng. "You brought this rare thing to me. I'm afraid it's not just to give me cigarettes, right? Tell me, what's your purpose?"

Behind Lin Feng, Zhao Jingyi, Su Sheng and others unconsciously tensed up their nerves, and the atmosphere in the room suddenly became a little different.

After all, for them, whether they can escape from this planet, Professor Liu can be said to be their only hope at the moment.

So Su Sheng and Zhao Jingyi couldn't help but start to get nervous.

But at this time, Lin Feng was calm. He reached into his pocket and took out a lighter. With a "click", he lit the flame and approached Professor Liu:

"Professor, you're really straightforward. I won't beat around the bush. We've heard you have research and unique insights into this planet's magnetic field, so we're here to ask, when will our planet's magnetic field disappear?"

The light blue flame flickered between the two of them, and Professor Liu's eyes flickered in the firelight.

After a long while, he took a deep breath of cigarette, exhaled the smoke slowly, and felt the pleasure that the cigarette brought him before he spoke:

"Since the cataclysm, the magnetic field above the entire planet has become extremely unstable. No aircraft can fly under such interference."

When Lin Feng, Zhao Jingyi and Su Sheng heard this, their hearts suddenly sank, and everyone's expression became solemn.

"Is there no other solution?"

At this time, Su Sheng on the side finally couldn't help but speak.

Professor Liu glanced at Su Sheng and said, "There is a way, but the chance is very slim."

Hearing this, Lin Feng stared at Professor Liu: "Tell me about it."

"More than 30,000 kilometers away from here, there is a plateau with the highest altitude."

Professor Liu said this as he walked to the wall, tapped his finger heavily on a dusty star map, and spoke again:

"There's an ancient observatory there. Legend has it that it contains a device capable of regulating a planet's magnetic field. It's called something called a stellar core resonance device. However, due to the harsh high-altitude environment there, the intensity of the magnetic field disturbance is far beyond imagination. Even the most advanced exploration robots couldn't survive there for more than three days."

"So, even if we can reach the observatory, we might not be able to get close to the device, and we might even risk our lives. Is that right?"

At this time, Zhao Jingyi, who had been silent, couldn't help but interrupt.

Professor Liu looked back at Zhao Jingyi and nodded, "That's right, so I advise you not to go. If you don't mind, you can stay here.

By the way, who are you, and why are you asking about magnetic fields?"

dong dong dong——!

However, at this moment, a rapid knock on the door suddenly interrupted the conversation between Professor Liu and Lin Feng.

So Professor Liu said impatiently towards the door:

"What's the rush? Come in?"

As Professor Liu finished speaking, the door creaked open. The guard looked panicked, with beads of sweat rolling down his forehead.

"Professor, a large number of Wang Wu's troops have appeared in the southeast. They are... they are rapidly approaching us!"

Professor Liu's face instantly turned pale when he heard this: "It seems that Wang Wu and his gang must be starving, otherwise they wouldn't dare to act so brazenly!"

"But Professor Liu, we've been running out of food in school for a long time. Everyone is eating porridge made from tree bark and roots. How can we give them any food?"

Lin Feng, who was standing aside, frowned after hearing the conversation between Professor Liu and his subordinate.

"Who is this Wang Wu?"

Professor Liu's eyes darkened as he fiercely extinguished his cigarette.

"This Wang Wu used to be the security captain of this school. After the disaster, he couldn't stand school life anymore and started to show his true colors.

This beast not only raped the teachers in the school, but also did not let go of the students who had just entered university.

Five years ago, I tried my best to drive him away, but I didn't expect that after he left here, he actually gathered a group of people outside, and his team has been growing stronger and stronger in recent years.

In my opinion, he came back this time not only for food, but also to avenge his previous humiliation.

If we had known this would happen, we should have killed him ruthlessly.”

As Professor Liu continued to speak, the atmosphere in the office became increasingly solemn.

At this moment, even the light outside the window became dimmer, as if reflecting the impending crisis.

After a brief silence, Lin Feng's eyes suddenly turned stern: "How many people came with Wang Wu?"

The guard trembled and replied:

"At least three hundred people, and they all brought weapons with them. It seems they have bad intentions. We heard that Wang Wu is now a mid-level earth-type mutant. He is very powerful now."

At this time, Professor Liu was pacing back and forth, and the sound of his heels hitting the ground was particularly harsh in the quiet office.

"There are less than a hundred people in our school who can fight, and even fewer weapons. If they attack..."

At this point, Professor Liu couldn't help but pause, his eyes filled with worry...
