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

[Completion of task: Recover three keys. 】

[Task evaluation: s +]

[Reward: 3 million free experience, 20,000 points, a golden legend lottery opportunity. 】

The so-called special reward of collecting three keys turns out to be a lucky draw chance of golden legend?

Lu Zhou originally thought that it would be something special, but did not expect the accidental "ordinary".

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

After all, according to previous lottery experiences, whenever the lottery opportunity has the prefix "Legend", the extracted things will not be the "trash" of the pit father.

As for the golden legend, it's even more terrible. All of them are good things.

The only thing Lu Zhou was worried about now was that he who had won the lottery had already overdrawn his character in advance. When the lottery was drawn, he couldn't draw good things because of his black face.

If that's the case, it would be a big loss.

"System, open the draw panel!"

The light golden light particles emerged from the system space, and as the group of light particles converged toward the center, a round wheel surface appeared in front of Lu Zhou.

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

Staring at the fast-rotating roulette, Lu Zhou meditated in prayer in his heart, and followed the feeling and pressed the draw button again.

Scanning gun! Scanning gun!

dry!

The hands of the roulette eventually passed by the prize he dreamed of, and after two more laps following the inertia, he stopped slowly.

Watching [Congratulations Host!] Appear on the holographic screen ] And after the pop-up [Draw, Nitrogen Shield (Rechargeable)], Lu Zhou's heart burst into tears and laughter.

Sure enough, this kind of game of luck with no mathematical logic is not suitable for Africans like him at all.

"... The only comfort is the" rechargeable "back?"

The first nitrogen shield drawn from the system space was a one-time use. On Flight n-177, he had exhausted that last bit of energy.

The remaining shield-generating device, like the other disposable samples used by Lu Zhou, was 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 provided him with an opportunity to understand the principle.

For how the shield generator interferes with the surrounding nitrogen molecules and compresses it into a shield for defense, Lu Zhou is also very curious.

At least in his cognition, this rare technology should not exist on earth.

A life-saving tool, coupled with the opportunity to light up new technology, from this perspective, 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 the land boat in the inventory, and continued to look at the attribute interface on the holographic panel.

Three million free experiences.

No doubt it's better than "big money".

The maximum experience from lv8 to lv9 is only three million. In other words, he can use this experience to make any subject directly upgrade from lv8 to lv9, and start the promotion task leading to lv10.

"The question is which one to choose."

A little difficult to choose ...

After about ten minutes of thought, Lu Zhou finally made a decision, allocating 937,000 experience to materials science, and all the remaining experience was allocated to engineering.

Considering that the Pan-Asian cooperation is advancing the space elevator program, it will be more appropriate to take materials science and engineering as the goals of the next stage.

The light blue light swept across the holographic screen, waiting for a moment, and the updated property panel quickly appeared in front of Lu Zhou.

[

a. Math: lv10

b. Physics: lv10

c. Biochemistry: lv8 (10,000 / 3 million)

d. Engineering: lv8 (2.063 million / 3 million)

e. Material Science: lv9 (0 / ?????)

f. Energy Science: lv8 (0 million / 3 million)

g. Informatics: lv8 (0 million / 3 million)

】

Looking at the upper limit of material science experience that turned into three question marks, Lu Zhou's face couldn't help but a touch of emotion.

Material science will soon reach lv10.

I have been promoted for a long time.

With the properties panel closed, Lu Zhou cast his gaze on the taskbar.

Unsurprisingly, the option to receive a promotion task has appeared in the list on the taskbar.

As the button for receiving the task was pressed, the light blue task window quickly appeared in front of him.

[Promotion quest starts! 】

[Task: Future Materials. 】

[Explanation: It enters the sky, then breaks through the earth, and obtains the ultimate power from all things good and bad. 】

[Requirement: This is the last question on materials science. Use "the most perfect material" to complete your graduation project. We will give you a reward based on your score. 】

[Reward: Material Science lv10 ,? ? ? 】

"... Future Materials?"

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

And this "graduate design" ...

It's a description full of bad taste.

At last, after confirming the requirements of the system mission, Lu Zhou closed the holographic panel and left the system space. The consciousness returned to the basement of Jinling Advanced Institute.

Because there was no good idea for the time being, Lu Zhou decided to leave things including Xiao Ai's server temporarily here, then stood on the elevator and left the basement, and returned to the top floor of the Institute of Advanced Studies.

Seeing Lu Zhou's return, the guide sister who was already anxious where he went was finally relieved, watching him jokingly.

"I thought you were lost here alone. I almost asked my male colleague to go to the toilet to find you."

"It's impossible to get lost. It takes a little more time to go to the toilet." A cough was heard, and Lu Zhou, who ended the topic, looked out the window. "It's getting late, thank you for staying with me for so long , I'll go back first. "

"Well?" It seemed a little surprised that Lu Zhou was about to leave so soon, Yang Lu said, "Are you not staying for a while? Are you going back just by looking at an office?"

Lu Zhou shook his head and said with a smile.

"No, I'm satisfied to see you protect my lab so well."

laboratory?

Isn't it an office?

The little sister of the tour guide gave a slight hesitation.

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

...

Returning to the doorstep by car, Lu Zhou lifted 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 yard's electronic door opened to the sides.

A path through the garden came into the house, and a new living room came into view.

When he was away, Xiao Ai already controlled the smart cleaning equipment here and cleaned the inside and outside of the entire house, not only replacing those old furniture with new ones, but also painting the exterior walls with a layer New paint.

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

At this time, Xiao Ai, wearing an apron, followed by a drone, hurried out from the corner of the corridor connecting the kitchen.

"Master, dinner is ready. When would you like to eat? (?? gt; wlt; * ??)"

"Now."

"Roger that!(????????????)????"

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

Soon, a table full of delicious food was served on the table.

The taste was as impeccable as ever, sitting on the land boat at the dining table while watching the news on TV.

Sitting across the table with his hands on his cheeks, while Ai was shaking her calf happily, watching the owner enjoy the fruits of her labor, the action stopped suddenly.

Not only that, but also the eyes 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 to be friendly."

Those ones?

It seems that more than one came.

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

"How far is Ling from here."

"About two kilometers."

Two kilometers does not seem too far.

There was probably a number in his heart, Lu Zhou nodded and said.

"Let it end standby and go home first."

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

Lu Zhou thought about it and said casually.

"You look at it."

"Anyway, try not to bother our neighbors."

Xiao Ai: "Received! (?? *` ???? *) ???? "
