Train Survival: You're really trying to survive!

Su Li was startled awake the moment Song Mingyu reminded her.

Just now, while he was keeping a watchful eye on his surroundings, his mind couldn't help but reminisce about the old days.

The most peaceful period of his life was during his senior year of high school. Back then, he didn't have to think about anything; all he had to do was study and do practice problems. Survival and conspiracies didn't exist for him; all he had was the desire for good grades, lunch breaks, and the spicy snacks sold outside the school gate.

Just as she was savoring the taste of her favorite baked bun, Song Mingyu reminded her.

Su Li stopped in her tracks, remaining on guard against any monsters that might have used mental interference against them.

After waiting for a while, nothing happened; instead, the mental intervention continued to take effect.

However, this kind of mental interference is too weak. It may subtly influence someone without their awareness, but it becomes useless once they are on guard.

"I didn't find any monsters. What about you?" Su Li asked Song Mingyu behind her without turning around.

Song Mingyu hummed in agreement, the magical energy in her hands flowing back and forth between her body and palms. After a few times, Song Mingyu said, "It's alright. The source of the mental interference was the wind."

"The wind?" Su Li asked in surprise. "You mean, this mental interference comes from the environment?"

This is really interesting; the environment here can actually have a psychological effect.

"The source is still uncertain, and we cannot rule out the possibility that a monster is using its abilities from a very far place."

Song Mingyu said rather meticulously, "Based on the information I've gathered, this mental interference is caused by the sound of the wind. It utilizes the effect of synesthesia. Mixed in with this chaotic and noisy wind are some peculiar sound waves. When we hear these sound waves, we will involuntarily recall past events."

"The mechanism of action is similar to when we listen to music. When you were on Earth, if you heard some sad songs, you would also feel sad. The mechanism is very complex, including the dopamine release mechanism, psychological association and memory, the physical properties of sound waves themselves, and so on."

Seeing that Su Li was a little confused, Song Mingyu stopped and explained, "In short, there are strange sounds in the wind that can make our brains make associations."

"How significant is the impact? Can it be prevented?" Su Li asked the crucial question.

"The impact is about the same as wearing headphones while walking normally. The interference isn't strong, but it will require some of your attention. For prevention, military-grade noise-canceling headphones will suffice. The downside is that there will be a slight delay."

Su Li took out the manual, found Zhang Qiang, traded six noise-canceling headphones, and then gave them to Song Mingyu.

Song Mingyu put on the headphones and continued, "This method is a physical defense. If the source is the Cursed Corpse, it will increase the magical energy catalysis, and then these headphones won't work."

After listening, Su Li felt a bit of a problem. "If only the train were still here, I could make some soundproofing items. Tsk, it's really inconvenient that we can't trade at the workbench."

Su Li could only ask the liaison officer, Zhang Qiang, to keep an eye out for any relevant magical items.

There isn't much demand for this kind of prop, and it's hard to find one in a short time.

"I'll do it." Song Mingyu took on the task. "I'll find teammates first, and during the break, I'll try to see if I can catalyze some plants."

Song Mingyu patted the special weapon on her waist. It contained a large amount of miscellaneous bloodline factors, along with the raw body seeds she had prepared, allowing her to adjust different functional plants on-site for different situations.

However, she still needs to think about how to debug it.

Su Li then led Song Mingyu to continue exploring the underground cave.
