Train Survival: You're really trying to survive!

Time soon came to night.

As night fell, the entire city heard the excited shouts of the zombies.

Meanwhile, inside the train, Zurich and Ivan were studying the dazzling crystal.

The more Su Li studied, the more serious her expression became. After a long while, Su Li ran to Song Mingyu's research room, pulled Song Mingyu, who was studying the zombie virus, over, and they analyzed it together.

After a long time, the expert report came out.

Su Li was shocked as she looked at the report.

Because this dazzling crystal is actually a crystallization of the life force of a planet.

In a world without magic, planets are very simple in nature; they are simply spheres composed of various substances.

However, in worlds with magical energy, especially those with an energy level close to 2, theoretically capable of supporting gold-level life forms, planets are not just rocks and water.

Planets with life generally become something similar to life forms.

On this planet, the River of Life flows, giving life to all living things. When each life form passes away, its life force, refined throughout its life, carries its soul back to the embrace of the River of Life.

This is the most basic configuration. In some worlds, it will be further divided, with life returning to the earth and souls returning to the underworld, and so on.

In short, this is a widespread way of life circulating within a planet.

The dazzling crystals in Su Li's and the others' hands are crystallizations of this River of Life.

What does this mean? It means that this event involves the planetary level.

"I see. In that case, the historical records make sense."

Su Li suddenly realized, "The alien meteorite brought a mutated zombie virus. Then, the planet released a life stream, which purified the zombie virus near the meteorite crater and saved life on the planet. With the help of the life stream, life in this world evolved. Their bodies became stronger."

"This purification process is based on tens of thousands of years. During this time, humanity discovered the role of planetary life crystals and, in turn, utilized these dazzling crystals to develop modern civilization."

Su Li could fill in the rest in her mind. Most likely, some people discovered the special effects of the zombie virus and then planned to use this power to become gods, so they spread the zombie virus.

That's how it's portrayed in anime and games.

"It seems I need to step up my preparations for the zombie virus." Song Mingyu picked up the few crystal stones. "Give me a few. Since these crystal stones can inhibit the virus, they must be helpful in developing a vaccine."

On the other side, Sofia walked over with a somewhat uninterested expression.

She threw the laser gun in front of Su Li and the others.

"What's wrong?" Su Li asked, puzzled.

"This is rubbish. The laser gun's power is solely due to the quality of the crystal material. It's a masterpiece by Li Dazhuanfei."

Sophia obtained the laser gun with the intention of using it as a basis to create her own magic gun, but the result greatly disappointed her.

"Then we can only pin our hopes on the treasure chests," Su Li said. "The guns that come out of the treasure chests have been enhanced by the system, so maybe we can get a suitable gun."

"I hope so." Sophia snuggled listlessly into Su Li's arms. "Hold me for a while, I'm angry."

Su Li affectionately ruffled Sophia's hair.

That night, the darkness deepened, white fog blanketed the city, and the entire city was shrouded in the terror of howling zombies. Su Li and her group were resting on the train when suddenly, a frantic cry for help came through their communicator.

"Captain Su Li! This is Li Feng! Blue Sky Base is under attack by a large number of monsters! We need your help!" Li Feng's voice was filled with obvious anxiety and panic.

"Don't rush, tell me what's going on," Su Li replied.

"We can't afford to be complacent." Li Feng spoke so fast it sounded like he was performing a stand-up comedy routine. "Several leader-level zombies are leading a large number of elite zombies. Our defenses can't hold them off!"

"Leader-level zombies," Su Li realized, "to translate, it means several Silver-level zombies are leading Iron-level zombies to attack the city."

Su Li frowned and looked out the car window. In the distance, from the direction of the Blue Sky Base, the sounds of explosions and monster roars could be faintly heard, and flames flickered in the sky, clearly indicating that the battle had entered a fierce stage.

Su Li sat up. A silver-level monster. He was a little interested. A silver-level monster meant a silver-level treasure chest. He was thinking of helping Sophia open some laser guns.

But we can't just blindly follow whatever people say; that would be beneath us.

Su Li said, "Sorry, it's too dangerous unless you offer something of value."

“We also have dazzling crystals, white mist crystals, and…”

Li Feng said a lot at once, but he didn't hear a reply from Su Li.

Li Feng gritted his teeth. "In exchange, I can provide you with special intelligence about the virus! This intelligence will definitely be useful to you!"

"Li Feng, are you sure your intelligence is worth the risk?" Su Li asked calmly, her tone completely unwavering.

"I'm sure!" Li Feng said urgently, "This intelligence involves the origin of the virus and the mastermind behind it! Many people have been investigating this. I can tell you everything I know!"

Su Li paused for a moment, then turned to look at her teammates. Sofia, Ivan, Sun Lili, and Song Mingyu all nodded, indicating their willingness to go and provide support.

“Okay, we’ll be right there,” Su Li said into the communicator. “But remember, if you try anything funny, you’ll regret it.”

After hanging up the communication, Su Li quickly issued orders: "Ivan, activate the train cannon and prepare for fire support. Sophia, you are in charge of long-range sniping. Sun Lili, be ready to teleport to support at any time. Song Mingyu, you stay on the train and are responsible for monitoring the virus's movements."

The train quickly changed direction and sped towards the Blue Sky Base. As they drew closer, the horrific scene of the battle became increasingly clear. A massive horde of monsters—including enhanced zombies, mutated beasts, and several gigantic zombie leaders—were relentlessly attacking the Blue Sky Base's defenses. Although the base's guards fought desperately, the defenses were on the verge of collapse under the onslaught of the monster horde.

"Ivan, target the elites, take them out first!" Su Li calmly commanded.

Ivan nodded and quickly adjusted the angle of the train cannon. With a deafening roar, an energy shell whistled out, hitting a zombie leader who was breaching the base's perimeter wall. In the massive explosion, elite zombies near the zombie leader were blasted to pieces.

"Sophia, clear out the monsters approaching the base!" Su Li continued to issue the order.

Sofia set up her sniper rifle and aimed at the monsters climbing the wall. Every shot she fired was incredibly accurate; the bullets pierced the monsters' skulls, instantly killing them.

First, we need to stabilize the front lines before we can deal with those leader zombies.
