"Hmm, so, where do we go now?" Butterfly Dance wanted to flap her wings, but the exhaustion from flying all day had left her with zero strength, and she had no energy left at all.

"Come back with me and rest first. I need to borrow your wings tomorrow." Mu Qingyun looked at her beautiful wings and had an idea.

They led the people back to their dwelling, where the rats and snakes were still diligently guarding the place. The snakes approached the rats, and the two switched places.

By the way, they take turns.

"Why are there so many rats and snakes?" Butterfly Dance became extremely vigilant, staring at the group of snakes that seemed to have come with ill intentions, and took out the laser gun from her storage bag.

"It's alright, we're all on the same side." Mu Qingyun strode inside first. When the snakes and rats saw her coming, they immediately made way for her to enter.

Seeing her walk in calmly, Butterfly Dance hesitated for a moment, but decided to carefully follow her inside.

"Rest for a while." She looked at Butterfly's wings and took out a piece of black cloth from her storage bag. "Can I touch your wings?"

Touching the wings?

Upon hearing this, Diewu was surprised for a moment, then looked down at the black cloth in Mu Qingyun's hand and suddenly realized something.

"No problem, you can come."

She flapped her wings, trying to spread them out as wide as possible so that Mu Qingyun could come up and measure their length.

She quickly measured the length and width by hand, covered it with the black cloth again, measured it, and finally took out a dagger and cut it to a length that could cover the wings.

"Your wings are too brightly colored. Cover them up at night so others won't spot you." Mu Qingyun stroked Butterfly Dance's wings, checked them again, and then took the black cloth back.

The two rested for the rest of the night and day, and luckily, they did not encounter any insectoids or abnormal virtual creatures.

As evening fell, Butterfly Dance rubbed her temples, her wings fluttering slightly behind her.

"By the way, do you know what a raw stone looks like?" Mu Qingyun asked while covering Butterfly Dance's wings with a black cloth.

She didn't have a thorough understanding of what was happening in this era. When she was in military school, she was busy with her training every day and didn't have time to learn about other things.

"You don't know about raw stones?" Butterfly Dance's eyes widened in surprise, completely unexpected that someone wouldn't know this.

"I don't know." Mu Qingyun shook her head honestly, waiting for Diewu to give her the "science lesson".

“Okay,” Butterfly Dance patiently explained to her, “Original Stone is a high-tech energy crystal that has been developed. Many of the mechanical armors here rely on Original Stone as their energy source.”

"What does it look like?"

All the previous science explanations are unimportant; what matters is what that thing actually looks like.

She doesn't even know what the raw stone looks like.

"They are crystal-like and come in four colors: red, yellow, blue, and purple. Each color of raw stone can only be installed in one type of mecha armor."

As she spoke, Butterfly Dance gestured in the air.

I understand.

In other words, each type of raw stone faces different dangers, and obtaining a raw stone requires accepting challenges, which is probably related to the color of the crystal.

"Alright, let's go. Let's take a look down first; maybe we can find Xiong Ruoyou and the others." Mu Qingyun finished tying the black cloth around her neck and made sure that the radiance of the wings was completely covered before nodding in satisfaction.

With Butterfly Dance holding her arms, Mu Qingyun was lifted into the air and carried there.

With the cover of darkness and the fact that they were both dressed in dark-colored clothes, it was easy to miss the two figures flying overhead unless you looked up carefully.

"Gagaga—"

However, before they had flown for long, a flock of vultures that appeared out of nowhere suddenly flapped their wings and flew towards them.

"There are vultures here?" Butterfly Dance looked at the small group of black animals, and quickly turned around with Mu Qingyun in her arms, flying in another direction.

Mu Qingyun frowned. Vultures usually act alone and rarely act in groups. She never expected to run into one.

Flames ignited at her fingertips, and with swift movements, she hurled the flames at the flock of vultures.

The flames climbed onto the vulture's body and instantly burst into flames, but the bright flames were too dazzling in the night, so she quickly put them back as soon as they started to burn.

However, after being scorched by the flames, the vultures were clearly frightened. They chattered amongst themselves for a while, but eventually scattered and did not dare to pursue them any further.

"Butterfly Dance, do you know where those raw stones are usually hidden?" Mu Qingyun looked down at the ground, which was full of ruins, with pieces piled up one on top of another, making it impossible to see what was inside.

She didn't know?

Butterfly Dance was stunned for a moment upon hearing this, then belatedly realized that she didn't even know what a raw stone was, so how could she possibly know how to find it?

"Didn't the military academy give you a compass? As long as you inject some mental energy into it, the compass will guide you to the nearest raw stone."

Mental strength?

Mu Qingyun frowned. She had heard of this thing, but had never used it. It wasn't that she didn't want to use it, but mainly that she didn't know the key points and didn't know how to use it.

Or rather, her mental energy was essentially initialized and unusable.

"What level is your mental strength at?" After thinking for a moment, she asked Butterfly Dance.

“The second stage has five levels,” Butterfly Dance replied. “There are four stages in total, and each stage has seven levels. The higher you go, the more difficult it becomes. After all fifty people who found the original stones have left, the mental strength test will begin immediately in the second stage.”

"You need to reach the seventh stage of the second phase of mental strength to be eligible to enroll."

The second stage, seven sections?

However, she doesn't know the extent of her mental strength; it's very possible that she doesn't have any mental strength at all.

"Orcs have stronger mental strength than humans because they don't have superpowers, so they are particularly outstanding in terms of mental strength. I'm only two levels away from reaching the standard."

That means cultivating mental strength must be quite difficult.

"Do you know what level of mental power the First Commander has now?" She was starting to get curious about Su Qiluo. She hadn't paid attention to mental power before, but now that she knew, she was particularly curious and wanted to know just how extraordinary he was.

"What I know is that two years ago, the Commander was already at the third stage, fifth level. This achievement, not to mention the Commander's age, is something that very few people in the entire universe could reach."

All right.

A hint of surprise flashed in Mu Qingyun's eyes. She originally thought that Su Qiluo, who had three superpowers, was already the only person in the world with natural abilities. She didn't expect that this person was far more abnormal than she had imagined.

No wonder everyone in Capa Dome, regardless of age or gender, loves him. Who wouldn't love someone with such top-tier strength?
