Back home.

Lu Xuan took a deep breath of fresh air.

Or the domestic moon is a little rounder.

"Meow, do you eat hot pot tonight, I haven't eaten hot pot for a long time. ”

Qiuqiu walked on the ground by himself, and then asked Lu Xuan.

I've always eaten steak and the like abroad, and Qiuqiu is a little tired of eating, and I want to have a hot pot at home.

"Don't eat. ”

Lu Xuan refused, he just wanted to sleep now.

In foreign countries, almost full attention is paid to every detail, and the drones are basically on standby in batches.

Now that I'm back at home, my nerves are relaxed, how can I still be in the mood to eat.

"It's back. ”

Lu Guoshi had been waiting at home for a long time, and he had heard about some things, so he was waiting for Lu Xuan to hand over the things to him now.

"Cell phone, USB stick. ”

Lu Xuan yawned and said, "There is a photo of me and my uncle in the phone, and the USB flash drive is what my uncle asked me to give to you, that's all...... Ni Meng and I went to sleep first, but we didn't sleep well on the plane. ”

He came back on a private jet.

When Qiuqiu and a cat flew alone before, they were placed in a cabin, and in order to avoid such a thing, Lu Xuan had to book a private jet and come back.

As for the money......

Spent from the punch card funds.

Lu Guoshi took these two things, and walked to the study on the second floor without saying a word.

He had been waiting for this day for a long time, but he didn't expect that his son would help him fulfill this wish.

"Let's eat supper first and then go to sleep, your eldest sister specially brought back your favorite dry fried beef river. Zhuo Lan felt more sorry for her son's experience abroad, so she pulled Lu Xuan to sit down and take a closer look at whether her son was injured.

"Meow!"

As soon as Qiuqiu saw that there was a supper on the table, he immediately jumped up.

"Let this cat eat it, I'm really sleepy. Lu Xuan said helplessly.

"Go to bed after eating, you haven't eaten much lately. Ni Meng saw that the family was waiting for him to come back, and he was embarrassed to go to sleep directly, so he said.

"Okay. ”

Lu Xuan had no choice but to nod and agree.

Lu Feifei said sourly beside her: "We advised you to refuse if you go to bed after eating, Ni Mengyi told you, you agreed very happily." ”

"You're sowing discord. "Lu Xuan didn't have a good airway.

"I'm telling the truth!" Lu Feifei snorted coldly.

Lu Xuan didn't bother to pay attention to her, looked at Lu Qianqian, and said, "Eldest sister, I'll give you a list, and you can help me buy all the materials back." ”

"What material?" Lu Qianqian walked over with a curious expression.

Lu Xuan handed over the tablet, which was full of drone materials and some other materials needed for high technology.

In about ten minutes, Lu Qianqian finished reading.

She was a little shocked and asked, "Brother, when did you develop in scientific research? Why don't I know?"

"You don't know how much you went. ”

Lu Xuan said: "There shouldn't be many of these materials in China, but a lot abroad, anyway, our family is not doing trade, I'll give you 50 billion, you help me buy all these materials back, you can buy as much as you can, 50 billion has to be spent all, and you can't have a dollar left!"

It's so tiring to spend money by yourself, it's better to let the eldest sister help him spend money.

In this way, the loss task of the system is completed, the technology building is in hand, and it is time for him to enter the plot of the technology boss.

There was a Tony Stark in the old world.

Now this world has, Tony Lu!

Lu Xuan thought to himself, there is no Marvel in this world, if he shoots the entire Marvel series...... Shhh

How can there be so much hesitation in the life of the hanging, just do it!

"Brother, are you really going to rob the bank?" Lu Feifei also walked over, her face full of shock.

50 billion!

She's never seen that much money in her life!

Where did Lu Xuan come from?

Zhuo Lan also took the tablet and looked at it, and said, "Son, don't scare your mother, why do you need so much money and so many materials." ”

"Alas, okay, don't pretend, I'm in a showdown. ”

Lu Xuan didn't bother to explain, anyway, as soon as the money was given, the Science and Technology Building might be about to come out, so it was better to have a showdown with his family.

As a result, a white drone appeared in mid-air, full of a sense of science and technology.

"This is a drone that I developed, and it has many functions and can be used for a variety of purposes, so you understand?" Lu Xuan said.

Lu Feifei asked curiously: "How powerful is your drone?"

Lu Xuan: "???"

Do you want to go to heaven?

Zhuo Lan saw the barrel on the drone and asked, "You also gave these drones to your uncle?"

"yes, yes. ”

Lu Xuan nodded and said, "Drones also have stealth and reconnaissance systems, with these things, the safety of the uncle is also more guaranteed." ”

He is not giving, but selling, and the uncle can only ask him to refuel, 99 million at a time.

With this kind of money earned for nothing, how could Lu Xuan not make it?

Now he still has 490 of them, and when the time comes, those 10 drones come back, he throws them into the system to charge, and then sends 10 drones over, it's perfect.

Zhuo Lan nodded slightly, she didn't say anything, Lu Wushuang was abroad all the year round and was in a very dangerous situation.

With the help of high technology, it may be much safer.

"Can these things be manufactured in batches?" Lu Qianqian realized the commercial value.

If these drones can remove some of the more dangerous functions, just the holographic projection function, there will definitely be a lot of people to buy it!

"I haven't tried it, and I don't have a few in my hand. ”

Lu Xuan said: "Wait until you buy me all the materials, and then I'll try again." ”

【Ding!Main Punch Quest Completed!】

[The Tech Building is being distributed, and the host will be notified when it is completed......]

[Reminder: If the profit of 100 billion punch-in funds exceeds the investment cost, the science and technology building will be suspended.] 】

Lu Xuan breathed a sigh of relief in his heart, as for the profit of the punch-in funds......

Is it possible?

As soon as the materials are bought, he will use the Science and Technology Building to make a series of consumables and burn them every day!

Until it burns out!

Moreover, the address of this science and technology building is also on the east bank of the Huangpu River, and it may be on par with the three classic buildings at that time.

As soon as the Tech Building comes out over there, it will definitely cause an uproar.

But......

The system should be able to solve this problem.

Otherwise, a building will pop up out of thin air, and everyone will be confused.

Lu Xuan suddenly ordered a new skill, which shocked the whole family, and Lu Qianqian even began to contact friends and began to help buy the materials on the list.

It's transformative technology!

If there are enough materials, my brother will definitely be able to create a technology similar to a drone!

Seeing that the eldest sister had been busy, Lu Xuan was also a little distressed, and said: "Eldest sister, don't work so hard, I'm not in a hurry now, there's no problem with you buying it back for me within two months." ”

"Two months? You're thinking too much. ”

Lu Qianqian said helplessly: "These things, if you can help you sort them out within half a year, it will already be very good!"

"What?"

Lu Xuan was dumbfounded, half a year?

So when will his tech edifice land?
