Train Survival: You're really trying to survive!

Gravel, everywhere is gravel. As a guardian of the power of the planets, Ivan is very fond of the earth.

Even in the sand, he could discern the unique helplessness and vicissitudes that belonged to the sand.

But the sand here is different; here there is only curse, only pain. The earth echoes with the sighs of a planet breathing its last breath after its death. Sand? There is no sand, only the cursed tears of the earth.

So Ivan hated this world, to the point that it was like seeing a person in the sweltering summer seeing someone make Mapo strawberry dumplings – it felt like little Guangzhou sprites were crawling all over him.

The moment Ivan left the silence zone, he immediately erected a shield.

The shield pushed all the sand and gravel aside.

In his arms, his wife Sun Keke rested her head against his chest, and at these moments, Ivan felt an inexhaustible strength within him.

The surrounding sand, like a swallowing throat, seemed to be automatically pulling Ivan and his companion downwards. The young couple clung to each other, wary of any potential danger.

After a long time, Ivan felt the pressure around him begin to decrease, which meant that the surrounding gravel was not as dense as before.

Sure enough, a short while later, the two were squeezed through a gap and fell from the sky.

A magical glow appeared beneath Ivan's feet, and the anti-gravity magic slowed his descent.

Only when the ground was covered with gravel did Ivan put Sun Keke down.

Sun Keke patted her Lolita dress and looked around. "I feel so much like we're being watched! There are so many people watching us."

"What about hostility?"

"There is hostility, but it hasn't erupted yet."

Ivan opened his eyes wide and raised his shield. "I will protect you."

"Yes, it's up to you, my prince."

A sweet smile appeared on Sun Keke's face, but dark magical energy surged from her fingers. The magical energy flowed into the eyes of both of them.

"This is Dark Vision."

Ivan understood Sun Keke's meaning. The pale golden light shield around him faded in color and eventually stopped shining.

Then, Sun Keke lightly tapped the jewelry box at her waist, and a thin layer of black mist enveloped the two of them. This was a fog used to conceal their presence. Conventional detection methods could not detect anything inside.

Only then did Ivan have the opportunity to check what this place was.

This place resembled a naturally formed mine, irregular in shape, with cavities of varying sizes. A faint, foul odor filled the air, reminding Ivan of the smell of fertilizer he had encountered back in his hometown.

Ivan and his companions landed at the edge of the cave.

Ivan dared not be careless. They had been discovered, but for some reason, no action was taken after their lives were discovered.

Suddenly, Ivan sensed a fluctuation, which to a normal person would be ultrasound. The frequency was very high, but still within Ivan's audible range.

The sound was simple, unlike what Ivan had sensed, which was some kind of telepathy.

The sound waves swept over Ivan and his companions before being swallowed by the black mist.

Sun Keke raised an eyebrow. "It's some kind of detection method. It contains sound wave detection magic."

The detection spell failed, and a rustling sound of skin rubbing against skin came from the ceiling. Then, a strong wind suddenly swept through the entire cave.

“Their reaction was off; it felt like a routine check,” Ivan said, frowning. “I have a bad feeling about this.”

"What a coincidence, so am I!"

Sure enough, as soon as Sun Lili finished speaking, several more detection spells rushed over. This time, the intensity of the detection spells was on a completely different level from the previous ones.

The mist released by Sun Keke stubbornly withstood the influence of the strong wind and sound waves.

One attempt yielded no results, and the creatures on the ceiling became even more agitated.

Two attempts had already made the tester lose patience, or rather, the failure of the two attempts itself told it the answer.

The next second, a sharp scream rang out.

"squeak!"

The ultrasonic waves, imbued with magical energy, formed an invisible sonic blade, sweeping across the black mist.

The black mist was dispersed by the sonic blade, but there was nothing left inside.

Not far away, Sun Keke, using the power of shadows, carried Ivan on a black flying carpet and headed in one direction.

"Go this way. I just did a divination, and this direction is very auspicious. Whether you're leaving or meeting up with your brother-in-law and the others, this is the right way to go."

The fact that the target would flee upon being detected further convinced the attackers that what had just fallen was not a cursed corpse, but a living being.

An ultrasonic wave spread through the group, conveying the message.

Then, numerous bright yellow dots appeared on the ceiling.

Countless rat-like squeaking sounds appeared, and the sound of flapping wings echoed in the cave.

Ivan looked up at the ceiling and confirmed that the monsters inhabiting this place were indeed a group of bat-like creatures.

“They seem to feed on spiders.” Sun Keke pointed to the thick layer of feces under the magic carpet, where some spider carapaces could be seen.

"That's strange. Why didn't they attack us immediately?" Ivan was full of questions. "And why are they so agitated?"

The sky was practically a sea of ​​bats, with countless bats flying in from all directions and fluttering around. Even with such a high density, no bats collided with each other and fell.

Their flight created signs of a surging black tide, as if the sky were brewing some monster that would devour its prey.

“What I find even stranger is why they’re so agitated? Why are they making such a fuss? It’s like their whole family will die if they don’t find us.” Sun Keke looked puzzled. “Is it to eat us? We’re only a few ounces of meat on us. Or do they have some other purpose? Are they simply vicious and vengeful, not allowing anyone to approach their lair?”

Ivan shook his head: "I don't know. If my brother-in-law were here, he might find out something. I just feel like they're plotting something. You strengthen the shield, I need to strengthen the defense. I can't control the shield's invisibility."

"Don't worry about it!"

Ivan closed his eyes and modified the shield, transforming it into a shield specialized for sound waves, vibrational resonance, and wind attributes.

Just as Ivan had guessed, after a long period of preparation, the numerous bats in the sky let out a unified scream.

The leader fused together countless magical energies of the same race, creating a massive sonic wave. This wave struck crystals protruding from the rock wall, activating them. These black crystals transformed into a bright white, unleashing a powerful sonic wave comparable to that of a bat.

These sound waves overlapped in the air, and even superimposed on each other.

When the superimposed sound waves encounter another crystal, the crystal is activated again, releasing sound waves and increasing their intensity to a higher level.

Ivan's mind began to calculate the intensity.

Activating it once doubles the strength; activating it again doubles the strength again; compared to the original strength, it's multiplied by four.

This is exponentially enhanced! It's even more outrageous than my own sister's enchanted bullets.

Ivan's mind went blank for a moment.

But he quickly realized something was wrong; the enhancement effect of this crystal was limited! It could only enhance the crystal by a maximum of 8 times.

Ivan slapped his forehead. "What do you mean it can only be enhanced 8 times?!"
