Chapter 1472 Material Science, LV9!

[Congratulations to the host, completed the mission: Holy Land Tour]

[Mission Completion Status: Recover three keys. 】

[Task Evaluation: S+]

[Reward: 3 million free experience points, 20,000 points, and a golden legend lucky draw chance. 】

Is the so-called special reward for collecting all three keys a chance to draw a golden legend?

Lu Zhou originally thought it would be something special, but he didn't expect it to be "ordinary".

Of course, the so-called normal is actually only for the rewards given by those "legendary missions". As a standard ordinary task, you can get a reward of 3 million free experience and a chance to draw a golden legend, even in terms of S+ task evaluation, it is quite good.

After all, according to previous lottery draws, as long as the lottery chance has the prefix "Legend", the things drawn will not be cheating [garbage].

As for the golden legend, it's even more serious, and all the ones that come out are good things without exception.

The only thing Lu Zhou is worried about now is that he has already overdrawn his character in advance when he got the chance to draw a lottery, and when the lottery comes, he will not be able to get good things because of his black face.

If so, it would be a big loss.

"System, open the lottery panel!"

Pale golden light particles emerged from the system space, and as the group of light particles converged to the center, a circular roulette appeared in front of Lu Zhou.

As the draw button is pressed, the roulette wheel begins to spin.

Staring at the fast-rotating roulette, Lu Zhou prayed silently in his heart, while following his feeling, he pressed the draw button again.

Scanner! Scanner!

Dry!

The pointer of the roulette finally passed the prize he had dreamed of, and after continuing to rotate two times according to the inertia, it slowly stopped.

Looking at the [Congratulations host! ] and the subsequent pop-up [Draw, Nitrogen Shield (Rechargeable)], Lu Zhou couldn't laugh or cry.

Sure enough, this game of luck without any mathematical logic at all is not suitable for an African like him at all.

"...The only consolation is the 'rechargeable energy' at the back?"

The nitrogen shield that was first extracted from the system space was a one-time use, and he had already used up the last bit of energy of that thing when he was on flight N-177.

And the remaining shield generating device, like other disposable samples such as the scanning gun used by Lu Zhou, degraded into black powder and dissipated in the air.

Although he didn't know what kind of energy this rechargeable shield needed, at least it gave him a chance to figure out the principle.

As for how the shield generator interfered with the surrounding nitrogen molecules and compressed them into a shield for defense, Lu Zhou himself was quite curious.

At least in his perception, such a strange technology should not exist on Earth.

A life-saving tool, coupled with the opportunity to light up new technologies, from this point of view, this reward is not too bad, at least there is nothing to complain about.

Finally, I checked the description of the nitrogen shield, turned off Lu Zhou in the inventory, and continued to look at the property interface on the holographic panel.

Three million free experiences.

There is no doubt that it is better than "huge money".

The upper limit of experience from LV8 to LV9 is only three million in total. In other words, with this experience, he can directly upgrade any subject from LV8 to LV9, and start the promotion task leading to LV10.

"The question is which one to choose."

It's a bit difficult to choose...

After deliberating for about ten minutes, Lu Zhou finally made a decision, allocating 937,000 experience to materials science, and allocating the remaining experience to engineering.

Considering that the Pan-Asian cooperation is promoting the space elevator project, it would be more appropriate to target materials science and engineering in the next stage.

The light blue light swept across the holographic screen, and after waiting for a while, the updated attribute panel was quickly presented in front of Lu Zhou.

【

A. Mathematics: LV10

B. Physics: LV10

C. Biochemistry: LV8 (10,000/3 million)

D. Engineering: LV8 (2.063 million/3 million)

E. Materials Science: LV9 (0/???)

F. Energy Science: LV8 (00,000/3 million)

G. Informatics: LV8 (00,000/3 million)

】

Looking at the upper limit of material science experience that turned into three question marks, Lu Zhou couldn't help showing a trace of emotion on his face.

Materials Science will be at LV10 soon.

Speaking of which, I have been promoted for a long time.

After closing the properties panel, Lu Zhou turned his attention to the taskbar.

As he expected, the option to receive the promotion task has appeared in the list on the task bar.

As the button to accept the mission was pressed, a light blue mission window soon appeared in front of him.

[The promotion mission is on! 】

[Task: Future Materials. 】

[Explanation: It goes to the sky and enters the earth, and then breaks out of the ground, obtaining the ultimate power from all things good and bad. 】

[Requirement: This is the last question about materials science. Use the "most perfect material" to complete your graduation project, and we will reward you according to your score. 】

[Reward: Material Science LV10,? ? ? 】

"...future material?"

Although for Lu Zhou himself, everything in this era is already the future, but in the eyes of the system, it is obviously not enough.

And this "graduation project"...

It's a really funny description.

After finally confirming the requirements of the system mission, Lu Zhou turned off the holographic panel, left the system space, and returned to the basement of Jinling Institute for Advanced Study.

Because he didn't think of any good solution for the time being, Lu Zhou decided to leave his things here, including Xiao Ai's server, for the time being, then got on the elevator and left the basement, and returned to the top floor of the Institute for Advanced Study.

Seeing Lu Zhou come back, the tour guide, who was anxious about where he went, was finally relieved, and joked with him.

"I thought you were lost here alone, I almost asked my male colleague to look for you in the toilet."

"It's impossible to get lost, it just takes a little longer to go to the toilet," Lu Zhou coughed lightly, and ended the topic and looked out the window, "It's getting late, thank you for being with me for so long , I’ll go back first.”

"Huh?" Seemingly a little surprised that Lu Zhou was leaving so soon, Yang Lu held back a sentence and said, "Aren't you going to stay a little longer? Are you going back just to see the office?"

Lu Zhou shook his head and said with a smile.

"No, I'm already satisfied to see that you have protected my laboratory so well."

laboratory?

Isn't it an office?

The tour guide was slightly taken aback.

However, Lu Zhou didn't intend to explain the meaning of this sentence. After saying goodbye, he turned and left.

...

After returning to the door of the house by car, Lu Zhou released the facial holographic projection system worn around his neck, and glanced at the iris recognition at the door.

Almost as soon as he moved his face closer, the electronic gate of the courtyard opened to both sides.

Walking through the path next to the garden to the house, a brand new living room greets you.

When he was away, Xiao Ai had already controlled the smart cleaning equipment here, and cleaned the whole house inside and out. Not only did the old furniture be replaced with new ones, but also the outer walls were painted. fresh paint.

If you don't look at the house book, you can't tell that this house is a second-hand house just by looking at it like this.

At this time, Xiao Ai, who was wearing an apron and followed by a drone, also excitedly ran out from the corner of the corridor connecting the kitchen.

"Master, dinner is ready, when do you want to eat? (>ω<*)"

"Now."

"receive!()"

Seeing Xiao Ai running back to the kitchen like a gust of wind, Lu Zhou couldn't help but smile, threw his coat on the hanger at the door, and walked towards the restaurant.

Soon, a table of tasty food was brought to the table.

The taste was still impeccable as always. Lu Zhou was sitting at the dining table while eating and watching the news on TV.

Sitting on the opposite side of the dining table with her hands resting on her chin, just as Xiao Ai was happily shaking her calves and watching her master enjoying the fruits of her labor, her movements suddenly stopped.

Not only that, but those big eyes also became alert.

"Master, there seems to be a guest outside. (-)"

"Guest?" Frowning slightly, Lu Zhou looked up at it and asked, "Who?"

"I don't know, but those guys don't seem very friendly. (ˇˇ)"

those?

It seems that there is more than one person who came to the door.

Putting down the chopsticks in his hand, Lu Zhou calmly picked up a tissue and wiped his mouth, then asked a question.

"How far is Ling's location from here?"

"About two kilometers."

Two kilometers doesn't seem too far away.

With an idea in mind, Lu Zhou nodded and said.

"Let it end the standby and go home first."

Xiao Ai: "What about the bad guys outside? ()"

Lu Zhou thought for a while and said casually.

"You watch and deal with it."

"Anyway, try not to cause trouble to our neighbors."

Xiao Ai: "Got it! (*`*)"
