From Abyssal Invasion to Bursting Stars with a Single Sword

In the training room of the Qionghua Tianglu Lake district.

Lin Zeyu yawned and asked, "What's up? I haven't slept enough yet."

"I need you to do a test, release a few Void Eyes." Lu Heng pointed forward, signaling him to use his skill.

Lin Zeyu was puzzled, but he complied, releasing three Void Eyes and then casually hiding them in the void.

The Void Eyes summoned by his skill couldn't move, but they had strong concealment abilities. Unless one had void detection capabilities, they wouldn't be visible.

Su Muyu closed her eyes, stepped back a few steps, and began trying to use [Energy Wave Sensing] combined with [Medium Control] to detect the Void Eyes.

A moment later, she opened her eyes and shook her head, "I can't sense them."

In a stationary state, the Void Eyes do not emit energy outward, so there is almost no energy fluctuation.

The use of "almost" implies that as long as there is an energy body, there will be energy fluctuations, but the stationary energy fluctuation of the Void Eyes is below the background energy of the environment.

Moreover, by concealing themselves in the void, under this double separation, they are undetectable by ordinary detection methods.

Lin Zeyu immediately laughed triumphantly, "Not even Miss Su can detect them, my skill is simply invincible."

Su Muyu's face darkened, wanting very much to give this guy a good punch.

Lu Heng continued with the next test: "Try using the observation capability of the Void Eye."

While in a stationary state, the Void Eye indeed has great concealment, but when it comes to observation or attacks, the situation changes.

Lin Zeyu controlled one Void Eye to open from the void and attempted to observe the main world situation.

At that instant.

Su Muyu suddenly opened her eyes, exclaiming, "I sensed it, very faint fluctuation, but indeed sensed it."

Lu Heng then asked, "Compared to the energy wave you sensed before?"

Su Muyu frowned in thought, "It's somewhat similar, but not entirely the same. Hmm... although not completely the same, I feel that the energy fluctuation detected earlier likely also originates from the void."

Lu Heng trusted her judgment and pondered, saying, "So, it means that energy fluctuations from the void appeared around me. It seems, indeed, someone is spying on me."

Lin Zeyu listened to the two's conversation, blinked, and asked, "What are you saying? Someone's spying on us?"

He turned his head to look around, his face full of confusion.

Su Muyu explained, "That wave appeared only once earlier, it probably isn't nearby now."

Lu Heng sat down and rubbed his brow with his fingers, beginning to think about a question.

Could this sudden void fluctuation have anything to do with the Spirit Communicators of the Saville Consortium?

Or perhaps, with Ke Yiming of the Liwei Mercenary Group?

Lin Zeyu suddenly had a whimsical thought and asked, "The next time this thing appears, can I see it with the Void Eye?"

Lu Heng's expression froze for a moment, replying, "Theoretically...not really."

"Why?" Lin Zeyu was extremely puzzled.

Lu Heng was surprised, "Have you not tested it yourself?"

"Test what?"

Lin Zeyu blinked, not understanding what it meant.

Beside him, Su Muyu couldn't hold it in and covered her forehead with her hand, speechless, "Haven't you tested it with the Void Eye? Can two Void Eyes, both hiding in the void, see each other?"

Lin Zeyu immediately gaped, "This... I hadn't thought of before."

He quickly released the Void Eye to test and then discovered helplessly, "Lu Heng, is there an issue with this skill? I placed two Void Eyes right next to each other, only one centimeter apart, but neither can see the other."

Lu Heng shrugged and replied, "The one centimeter you mentioned is just the distance in the main world; there's no scale of distance in the void."

"What do you mean?"

Lin Zeyu felt like he was hearing something very hard to understand, as if he were in the clouds.

Su Muyu shrugged to help explain, "It's simple, the laws of the void are not the same as those of our three-dimensional world.

"So you can't view the void through the lens of the three-dimensional world; length, width, height, distance, space, these characteristics are traits of the three-dimensional world, which don't apply in the void.

"Therefore, the two Void Eyes' distance of only one centimeter means the distance between their corresponding positions, not the distance in the void world."

Lin Zeyu scratched his head and asked, "This is too complex, just tell me, what should I do?"

Lu Heng shrugged, "There's nothing you can do."

After a pause, Lu Heng added, "Actually, the act of 'observing' requires a 'organ' to receive information, as well as a medium to transmit the information.

"For example, humans have vision because there's light in the human world; light is the carrier of information.

"Additionally, humans need an organ to receive light, which is the eyes.

"Thus, the process of 'observing' requires these two necessary conditions to be fulfilled in order to be completed.

"Your Void Eye belongs to the observing 'organ', but to observe things, it needs a medium to transmit information.

"Obviously, there is no light in the void, so you can't see anything."

Lin Zeyu began to learn to extrapolate: "Then can I make a void eye emit a ray? The ray emitted by the Void Eye is quite bright."

After his [Void Eye] skill upgraded to B-level, it gained attack capabilities and could emit rays from the void to attack targets.

However, he rarely used this ability.

Because the most important function of the Void Eye is concealment and observation, when it comes to attacking targets, shooting directly is just fine.
