Train Survival: You're really trying to survive!

After the little scarf incident, Su Li finally had a free hand and took out her prop.

“Fog clearing agent. A support item given to us by Old Deng.” Su Li took out several vials of the medicine. “I studied them before and reverse-engineered a new tool.”

After saying that, Su Li took out several round balls.

Clean Ball

[Iron Grade]

[After throwing, it releases a purifying wind of the wind attribute within a 3-meter radius, and uses the life-giving fire to remove any residue from the body.]

“Underground, you may encounter adhesives, miasma, asphalt, and oil. After you throw it down, a flame will spread with the wind. This fire is the power of my life force, which can purify the things I mentioned earlier.”

Zuli made a lot of these, giving 10 to each person and telling them to keep them safe.

After all preparations were completed, Zurich started the train.

Under Zuli's control, the train tracks plunged deep into the vast canyon, constantly contacting the gelatinous walls and spiraling downwards.

Zuli turned on all the train's lights. The incandescent headlights cast shimmering spots of light on the gel walls, and the translucent green gel trembled slightly as the train passed, like the mucous membrane of some giant creature.

Countless fragments of minerals floated inside the walls, reminding Su Li of the aspic she had eaten before. As they went deeper, the surrounding light became increasingly eerie. The gel's excellent translucency allowed sunlight to still penetrate, but it was tinged with a greenish hue, creating a bleak atmosphere, as if they had entered a horror movie set.

Deeper within the gel, shadowy figures swam—some kind of multi-legged creature, its carapace shimmering with iridescence as it passed through the bands of light. They moved their appendages as if swimming, leaving behind slowly closing tunnels.

The light on the left suddenly dimmed considerably, and a swollen shadow appeared on the side wall. The gel surface, bulging and then flattening due to the passage of the large monster, revealed a long, slender creature gliding along the edge. Its segmented body contracted and expanded intermittently, observing Su Li and her companions' train through the gel. The summoned Ember Shadow inside the train released its silver-level aura, silencing the enormous monster for a moment. Soon after, the light returned to normal, and it finally burrowed deeper into the gel layer.

Just then, an aftershock occurred, and the surrounding gel began to tremble.

Above, as the earth was torn apart, sections of gel separated, resembling pillars that swayed back and forth. Every now and then, pieces of gel would suddenly detach and fall into the depths of the abyss. One of them landed with a thud on the roof of a carriage below.

The train's barnacle armor perfectly defended against these attacks, and tentacles even extended from the seams of some of the armor, grabbing the gel and eating it.

Finally, after a depressing decline, a new change occurred.

Zuli, who had been staring outside, noticed a green glow emerging from the ground. This glow felt somewhat cold. The intensity of the light wasn't high, but its presence was undeniable.

Amidst the vigilance of the crowd, the train entered a huge hollow.

Zuli maneuvered the train to a stop in the hollow, and then the group came to the outside world.

"This place is quite spectacular."

The surrounding gel walls abruptly end here, replaced by a towering, arched structure. The dome is not smooth; it has a structure resembling a pile of stones, and is also covered with tiny honeycomb-like holes.

Many monsters lived in these hollows. When they saw Su Li and her companions arrive, they poked their heads out and looked over curiously.

The entire wall was made of emerald green crystal, which looked very much like the skeletons of various creatures on the ground.

Cold light seeped from deep within the bones, illuminating layers of intersecting bony plates, like hollowed-out coral, riddled with cracks and tunnels. Some places had collapsed, forming abyssal gaps, while others twisted and climbed upwards, like solidified waves.

Su Li felt as if she had entered an insect hive, but upon closer reflection, it also felt very familiar.

He carefully dug into his memories and finally remembered.

This is somewhat like when he was in the orphanage, the director cooked a big bone soup and gave him bones to gnaw on—the spongy bone inside the femoral shaft.

That is, when you eat bone marrow, you use chopsticks to push it in, and you find the parts that feel good to the touch deep inside.

"Good heavens, it really is the corpse of a giant beast?"

Su Li looked up at the enormous underground space and thought, "It's so big, how big of a pot would we need?"

To expand on that idea, this might be a behemoth the size of a planet.

Su Li looked in the direction they had come from; there was a huge crack with very smooth edges, indicating that the gap had existed for a long time. It was unclear whether the gap was formed by geological changes or caused by local organisms. The traces were too ancient to discern the cause.

After the initial shock, Su Li reverted to his player nature and began to ponder what resources he could obtain from this place.

Su Li stepped on the crystallized bones beneath her feet. She drew her greatsword, channeled her magical energy, and unleashed her sword aura, easily slicing bone off the ground.

He tossed a bone fragment to Ivan, and Zuli began to analyze the bone based on his experience.

After a long while, he came to the conclusion: "It's useless. Too much time has passed, and the internal magical energy and special substances have dissipated. Its quality is even worse than the bones of monsters outside."

It's fine to grind it into bone meal and use it as fertilizer, but its value is so small that it's not worth Su Li and his team stopping to mine it.

"It's alright, there's still a lot here, we'll take our time to look through it."

The train slowly moved towards the lower layers of the skeleton.

"If there is anything left, it should have fallen to the bottom due to gravity. Let's go to the bottom and take a look."

As the train descended, more things appeared around it.

In addition to the crystallized bone platform, some red and green aggregates appeared, adhering to the bone platform and looking extremely disgusting. These aggregates were also constantly dripping emerald green liquid.

As you go deeper, the number of these aggregates increases, sometimes blocking out a large area like a mountain of flesh, covered with a large amount of gray-green aura, making them look extremely dirty.

Around the mountain of flesh, there are some special monsters. Their appearance is generally like that of four-legged dogs, spiders, or fleas. One is good at running, one at climbing, and one at jumping. They rarely hunt each other.

Su Li didn't know how long they had been descending when they finally saw something different.

It was a sea of ​​fluorescent green.
