Standing in a pure white space, walking in front of the translucent holographic panel, Lu Zhou finally saw that line of reassuring prompts.

[Congratulations to the host for completing the urgent mission "Call of the Void."] 】

[Mission Completion: The path to the truth is not always easy, and there are too many endless and mysteries hidden in the vast universe that we do not understand. Like the song of the Siren in the stormy waters, only the strong-willed can pass the test and go to the legendary ideal ......]

[Mission Evaluation: S+]

[Rewards: 1,000,000 Physics Experience, Void Explorer Medal, Gift from the Void (S-Level Evaluation Bonus), +10 Earth Civilization Materialist Tradition.] 】

A million experience rewards is a lot of money.

Looking at the pale golden particles of light pouring from the task panel to the progress bar in the attribute panel, Lu Zhou's face showed an old father-like smile.

How long has it been?

He had almost forgotten the feeling of joy.

The reward of this mission can be described as a bumper harvest, and the physics level that has been stuck at the door of LV8 for an unknown amount of time has finally taken a big step towards the gate of LV9.

It's just that what Lu Zhou can't understand is what this Void Explorer's medal is.

"Last time it seemed to be the Order of the Savior of Civilization...... Is there any special point in collecting this thing? ”

Or is it that the honor is too much, and the observer civilization from the void will issue him a visa or an honorary citizenship card or something.

The pale black streamer floating in his hand was like a beating heart, and the palm of his right hand dragged it, and Lu Zhou's palm felt a faint warmth.

Compared to the stout Civilization Saver Medal, this "Void Explorer" medal is very light. With the exception of a bronze button the size of a thumbnail that can be pinned to the chest, which is a real entity, the rest of the space is as if it were a projection of some kind of holographic technology, beautiful and illusory, like the void itself.

It's just that it's more advanced than the holographic technology on Earth, it doesn't require water vapor as a medium, and it doesn't use the Tyndall effect at all, as if it directly projects an image into reality, making it impossible to guess how it does it just by looking at it.

Watching it change form in the palm of his hand, Lu Zhou, who had been observing for a while, put it back in the inventory, and placed it side by side with the Medal of the Rescuer of Civilization.

Perhaps, in the distant future, after the veil of the void has been completely lifted, he will have the privilege of knowing the true meaning behind these medals. As for now, it's better to leave it as a collector's item and leave it alone.

In addition to that medal, the reward of the system also has a bonus that belongs to the S+ rating.

I don't know if it's because it's too salty, but in Lu Zhou's impression, it seems that he has not been evaluated above the S level for a long time.

Looking at the holographic panel, the floating [Do you open the gift of the void?] Lu Zhou cleared his throat and ordered.

"Turn on!"

Almost as soon as the words fell, a pale blue light floated out from the holographic panel, half an inch closer to the landing boat.

Looking at the light purple light that was suspended in front of him, flickering and dimming, Lu Zhou hesitated for a moment, then took the initiative to stretch out his right hand to it, and his fingertips touched the core of the light.

It wasn't quite what he expected.

Instead of being rude as when reading Void memories, it was replaced by a warm current that enveloped his fingertips.

Slightly stunned, a strange expression appeared on Lu Zhou's face.

"Subspace? Or is it ...... Fragments of some kind of high-dimensional existence? ”

"Incredible......

His entire hand didn't pass through the light, but plunged straight into it, into a mushy, viscous space. And that space is even deeper, at least far more massive than the actual size of that particle.

Stretching his entire arm in, just when Lu Zhou was puzzled about what this void was trying to give to him, his right hand suddenly touched something hard.

Almost subconsciously, Lu Zhou reflexively grasped it and pulled it out of the lilac light.

As soon as his right hand was completely withdrawn from the light, the lilac light quickly shrank into a dot and disappeared into nothingness.

And Lu Zhou also felt his clenched fists sink slightly, and the hard and cold texture gradually came from the palm of his hand.

"It's ......"

Spreading out his palms and looking at the metal round pipe about the size of a fountain pen, Lu Zhou's face gradually showed an expression of interest.

On one side of the metal cylinder, there is a translucent glass groove with a graduated mark, through which a small section of dark green liquid can be seen.

Shaking it slightly, watching the viscous liquid crawl slowly in the glass tube like a gel, the expression of interest on Lu Zhou's face became stronger and stronger.

"Nutritional mixtures? No, it shouldn't be such a garbage thing. ”

His intuition told him what special biomass it should be, or a chemical that would give the organism a beneficial effect to life.

Of course, it is not excluded that something is dangerous.

It's just that so far, the observer civilization has shown him more than neutral goodwill, and if you really want to trap him, you won't bury this pit here.

"Anyway, let's take it to the lab for testing first."

Thinking of this, Lu Zhou immediately withdrew from the system space, jumped up from the bed in the bedroom, and took out his mobile phone to call Wang Peng.

"Come downstairs and pick me up."

"Roger."

After a while, the sound of cars could be heard outside the villa, and a bunch of headlights could be faintly seen through the window.

Lu Zhou, who went downstairs, asked Xiao Ai to take care of the house, and then went to the cloakroom to change his clothes, put on his shoes and went out.

When he walked through the open courtyard gate to the side of the road, the Zidian new energy vehicle had already stopped under the street lamp.

opened the car door for Lu Zhou, and Wang Peng, who returned to the car, asked casually while starting the car.

"Are you still going to the research institute so late?"

"Well," Lu Zhou, who took out his mobile phone and connected to the database of the Institute for Advanced Study, looked up the use arrangements of various biology laboratories, and replied casually, "Because there is something I can't wait to figure out." ”

Can't wait to figure something out?

Although he was very curious about what it was, he thought that he would be confused even if he heard it, so Wang Peng didn't say anything, and concentrated on driving the car to the parking lot of the Institute for Advanced Study.

Turning off the engine, he turned his gaze to Lu Zhou.

"Do you need me to wait for you here?"

While unbuckling his seat belt, Lu Zhou replied: "No need, you can go back first." ”

Wang Peng: "Are you sure you don't need to?" I don't really care. ”

"Sure," Lu Zhou nodded and glanced in the direction of the research institute, "I plan to stay here for one night today, and I probably won't go back for a while." ”
