Train Survival: You're really trying to survive!

Su Li and his team spent half a morning collecting all the ore in the entire mine.

Inside the mine, besides silver and gold mines, there were also some magic energy crystal mines, which provided Su Li and his group with some lower-grade magic energy crystals.

While mining, Su Li discovered a new use for Mountain Slide. Using Mountain Slide for mining, due to the shockwave, was far more effective than using a pickaxe. One strike activated the shockwave, instantly filling the ore pile with cracks; two strikes shattered a medium-sized ore pile. Only some durability was consumed.

Durability can be restored in the combat preparation room.

Besides the mineral deposits, there's another piece of good news: bullets made from explosive spores are more powerful, 1.5 times more powerful than those made with nitrocellulose gunpowder.

So Zuli and the others also began collecting these mushrooms.

After the mushroom releases its concentrated spores, Zuli will freeze them with her ice sword technique before collecting the remaining spores. The concentrated spores, after decomposition, yield three portions of spores.

One mushroom is equivalent to four spores, and one spore is equivalent to 10 enhanced bullets. A total of 51 mushrooms were collected from the entire cave.

This wave completely drained Zuli's magical energy.

Song Mingyu took some spores, wanting to try cultivating this magical mushroom. However, considering the dangers of this thing and the final harvest, Su Li judged that the risks and rewards were not proportional.

To cultivate these mushrooms, you need to keep a constant supply of seawater from this world inside the vehicle. You also need to maintain the temperature at a suitable 40°C for growth. It's extremely labor-intensive, and the harvest cycle is long. Harvesting a batch of wild ones is enough; cultivating them yourself is simply not cost-effective.

Ultimately, Su Li rejected this idea.

The monster that resembled a garden eel was sniped by Sophia. This monster matched Su Li's assessment; it was a Type 6 monster, relying on camouflage to ambush. Once its disguise was exposed, it was easily killed.

Some eel meat was harvested from it. At noon, Zuli grilled it and ate it; it tasted quite good.

After collecting all the props, Su Li and the others returned to the train.

Then ignite the fire and continue the journey.

After leaving the area that appeared as a yellowish-brown color on the map and was called the mud and sand zone by Zuli, Zuli and his group arrived at the green algae zone, which was mainly yellowish-green.

Once inside the algae-covered area, the surrounding ecosystem improved significantly. Through the windows, one could occasionally see schools of fish swimming gracefully. As the train passed, large numbers of crabs and shellfish lurking in the mud were stirred up, creating a rather comical scene.

Meanwhile, along the way, Su Li and his group encountered several mining areas and spent some time mining.

In their spare time, Su Li and his friends exercise and read books, and for a while, they felt a sense of peace and tranquility.

This feeling lasted until the morning of the third day, when they left the green algae zone and entered the deeper red algae zone.

As the train continued to venture deeper into the ocean, they reached increasingly greater depths. By the time they entered the red algae field, the train had reached a depth of 100 meters.

At this depth, the seawater, under the sunlight, has a misty feel, gradually highlighting the profoundness and unknowability of the deep sea.

The ground in the silt zone is mostly silt, the green algae zone is mostly soil, while the red algae zone is completely different from the previous two.

The terrain of the red algae zone is dominated by rocks, with hard, dark blue rocks everywhere. Large amounts of red algae take root in the rocks and grow all the way to the sea surface, blocking out the sun's rays.

The entire red algae area is a massive slope stretching for hundreds of kilometers. At the lowest point of the slope is a precipitous cliff, as if a giant had cleaved this section in two with a knife. Su Li and the others didn't know how deep the cliff was, because according to the map, one side of the cliff was red, while the other side was endless darkness.

Of course, there are advantages too. One advantage is that their trains stir up much less mud and sand.

Zuli and his group's route required them to traverse the very center of the entire red algae field in order to reach the deeper, more colorful area.

Red algae areas are undoubtedly more dangerous than muddy or green algae areas.

The area is rich in red algae, resulting in very low visibility. It's also abundant in marine life, making it a natural paradise for predators. Zurich has seen shark-like predators with sharp teeth and claws swimming near the train on more than one occasion.

Besides the threat from marine life, the biggest threat to red algae-covered areas is the unique and ever-changing ocean currents.

The deep seawater here is not static. The complex topography creates some unique natural phenomena.

Every half hour, the ocean currents here change direction.

The ocean current first surges from the seabed towards the red algae area, and half an hour later, the current changes direction again, surging from the red algae area towards the endless abyss.

The ocean current was quite strong; Zurich's train even tilted at a certain angle due to its direction. However, they were inside the red algae, where the currents had been significantly weakened.

Along the way, Su Li and his companions tilted to the left and then to the right, looking rather disheveled.

The first time Su Li encountered this, she was terrified, fearing that her train would be dragged into the abyss by the ocean current. If she fell into the abyss, she would be completely helpless, and if she was unlucky, she would simply perish in this world.

These ever-changing ocean currents wash nutrients from the deep ocean to the shallows, and at this time, red algae will open their brush-like leaves to absorb rich nutrients from the seawater.

The ground in the red algae area is not a single piece; it has many caves carved out by the ocean. Every time an ocean current surges into the red algae area, these caves also spew out large amounts of ocean current. When the current recedes, these caves become whirlpools, pulling the surrounding creatures back.

If you're outside, you could easily be pulled into a cave, and getting out would depend on luck. Nobody knows what the caves beneath the rock strata are like, and if you get lost inside, there's virtually no chance of survival.

To cope with this situation, Zurich also commissioned Ivan to make some special climbing spikes for everyone. Normally, they would be tied to their waists with ropes, and if this happened, they would drive these spikes into the ground to hold them up until their teammates came to rescue them.

On the afternoon of the third day, as the train traveled to the central area of ​​the red algae zone, the radar suddenly sounded an alert, informing Zuli that large silver and gold mines had been discovered.

Zuli maneuvered the train to the nearest stop.

Several people put on their gear, entered the disinfection room, and prepared to get off the vehicle to mine.
