After leaving from Zhao Wenlong, Xu Yuan thought about it and simply walked directly towards the outer circle of the safety zone.

It's been almost two years, from a barren dilapidated manor to a huge safe area manor now, Xu Yuan also wants to take a good look at what state the current safe zone has developed.

Compared to a year ago, it is indeed a lot more prosperous, and the buildings on both sides of the street are the kind of three- and four-story high-rise buildings.

Just standing here, if you don't look up at the gray radioactive dust above your head, you really can't feel the breath of the end times.

Bustling crowds, dazzling array of goods, lone travelers with rifles haggling with vendors in front of their stalls, and soldiers in combat uniforms maintaining order in the market.

In addition to the usual survivor attire, survivors can occasionally be seen dressed in distinct attire from the locals, either from other nearby safe zones or from further afield Eighth District.

They brought alongside crystals and goods, but they also brought with them technologies that were lacking here, such as a very useful smart camel that could carry up to 100 kilograms of weight across all terrain, making it easier for waste pickers to carry more garbage.

Initially, the slum had been bulldozed and apartment buildings were built, most of which were private properties and a small number of shelters.

There are no more refugees waiting to die on the streets, and anyone with able-bodied hands and feet can find work here.

To say how different it is here than it was a year ago. That's probably civilization.

"Everyone, don't miss it when you pass by! Fresh black rice! Come and take a look! ”

A hawker's shouting attracted Xu Yuan's attention.

The small shop was crowded with onlookers, and two men helped him carry bags of grain onto the scales.

The peddler in the animal skin suit shouted and took the customer's money, and then handed the customer a bag of bullet shells.

"Black rice?" Looking at the bags of grain with some surprise, Xu Yuan leaned over and asked the vendor, "How is this thing sold?" ”

"One pound and two yuan crystals, no bargain." The peddler didn't know Xu Yuan, and directly regarded him as a customer, and it was obvious that he should be from other places.

Slightly cheaper than the price of rice?

Xu Yuan frowned slightly, and asked, "Where did this thing come from?" ”

The peddler glanced at Xu Yuan vigilantly, and did not answer, only said: "You don't buy it, if you don't buy it, let it go, there are so many people lining up behind!" ”

Xu Yuan smiled, and without repeating it, he directly took out two source crystals the size of rice grains from his pocket and threw them into the hands of the vendor.

"Give me a pound."

Seeing Yuan Jing, the vendor immediately smiled and handed over a bag of black rice.

Just when Xu Yuan stopped to observe the black rice, Ning Hui in the back suddenly came over and whispered to Xu Yuan.

"Oh? Are you saying Miao Wenke is back? Let's go meet him. ”

Xu Yuan was slightly excited, this guy said that he wanted to get a batch of slaves for himself back, Xu Yuan was still quite curious about the value of this batch of slaves.

When he arrived at the warehouse area, Miao Wenke had been standing at the door and waiting for a long time.

Seeing Xu Yuan, Miao Wenke's eyes lit up, and he hurriedly greeted him enthusiastically.

"Hehe, Boss Xu, let's meet again. I have brought the slave you wanted. ”

"What about people?" Xu Yuan glanced behind him, and there was no one.

"Ahem, of course it can't be here, now the slave business is carried out in the shelter outside the walls, that's your rule." Ning Hui leaned over and explained to Xu Yuan.

After being stunned, Xu Yuan didn't care, it may be the rules set by Shen Xi, probably to facilitate management.

The three of them came to the slave trade area together, and after paying the source crystal, the more than 1,000 slaves were transferred to his name.

Then, led by the soldiers, the ragged slaves walked in the direction of the underground passage.

They will be taken to the former Vault 953, now Boot Camp, where they will undergo three months of military training.

If they pass the examination, they will be freed from slavery status and integrated into the army, and those who cannot pass the examination will be sent to the colony to work in production.

After receiving Yuanjing, Miao Wenke smiled happily, he made a lot of money this time.

After thinking about it, Xu Yuan opened the black rice bag in his hand again, and asked Miao Wenke at the same time, "Do you know the origin of this thing?" ”

After glancing at the probe, Miao Wenke replied, "Black rice, is it?" I know that the survivors in District 8 are growing this kind of thing, and it was only recently that this edible black rice came here along the trade routes. ”

"How's this stuff being produced?" Xu Yuan frowned and asked in a deep voice.

"The yield is very objective, but the soil quality requirements are very harsh, only the land with a pollution degree and radiation value of less than 15 can be planted, and the ninth district is not to think about it, the land here is not suitable for planting."

"Doesn't this strange crop accumulate toxins?" Xu Yuan asked with some confusion.

He has the impression that most of the plants in the wasteland cannot be used, mainly because the toxins in the soil will accumulate into the plants, which is also the reason why the bitter grass is inedible and can only be used as a raw material for nutrient mixture.

"This black rice is very special, and the toxins are basically accumulated on the ears of grain, so the millet is not harmful to the human body." Miao Wenke said after thinking about it.

This is not good news, this kind of black rice spread to the ninth district along the trade route, which is bound to have an impact on the grain business monopolized by Xu Yuan.

Although this kind of thing is not as good as white rice in terms of texture and taste, it is still an alternative option for poor people who cannot afford to eat rice.

After sighing, Xu Yuan waved his hand to let Miao Wenke leave.

He didn't have any good idea now, it was impossible to ban the sale, and once it was forbidden, the poor would definitely leave.

Population is the most important thing in a safe zone, so Xu Yuan will never do this kind of self-digging grave thing.

Therefore, now we can only wait for the development of the situation, if it is just black rice, Xu Yuan can still allow it to exist.

Back at the villa, in the study, two virtual mirror cabins were placed in the corner, and at this time, one of them was shining with a light blue light.

Shen Xi has been in charge of testing virtual reality online games these days, although at first she was very unimpressed with this game called free fantasy, but as she played, she found that the game was unexpectedly interesting.

Shaking his head helplessly, Xu Yuan walked to the side of the virtual reality game pod and pressed the wake-up button on the game pod shell.

This button acts as a doorbell to notify the user who is in a VR game that something is going on in the real world.

Soon, the game's pod's light turned from blue to white, and the hatch slowly moved away.

"Is it fun?" Xu Yuan said with a smile.

"That's it, what's wrong? Looking for me? Shen Xi pouted and said a little dissatisfied, of course she was just dissatisfied with Xu Yuan waking herself up, not dissatisfied with the quality of the game.

"It's time to eat, what do you say?" Xu Yuan said helplessly.

What Shen Xi is showing now is not at all like "that's it".

However, Xu Yuan is also very pleased to see that this game is so attractive, even if half of the world's netizens are addicted to this game, he will become the richest man in the world.

"Huh? It's seven o'clock! After looking at the time, Shen Xi's cheeks were slightly red.

Although she is the only one playing the whole game, the NPCs have a high IQ, and even if it is a stand-alone game, the main story is unexpectedly interesting.

However, after hearing that he couldn't "do anything" for the time being, Xu Yuan lost interest in this game, and now it has become Shen Xi to explore the mystery of this online game alone.

"That's right, Internet addict girl, it's time for us to eat." Xu Yuan stepped forward and hugged her out of the virtual reality cabin.

"What are you eating?" Leaning on Shen Xi with great enjoyment, Xu Yuan asked lazily.

"Eat the small buns first, and then I'll eat your big buns!"

Hehe smiled, Xu Yuanfei also hugged her out of the bedroom.

A night of excitement.

Early the next morning, Xu Yuan got up early in the morning, and then came to the scientific research room again.

This time, his purpose was clear.

As soon as he entered the door, he directly called Su Hongtao, who was currently in the research room, to a room alone.

After the two sides sat down, Xu Yuan directly said to Su Hongtao, who was nearly 50 years old: "Mr. Su, I plan to set up an aerospace science and technology research institute, with you as the director, I don't know if you have any ideas?" ”

"Institute of Aerospace Science and Technology?" Su Hongtao was stunned, although he was in charge of aerospace technology before, but this will be after the war, and the entire planet is wrapped in radiation clouds, what is the use of studying aerospace technology?

After pondering for a moment, Su Hongtao asked with some confusion: "If you need anything, just tell me directly, you don't need to set up a research institute for this at all, the price is too great!" ”

The investment in the space industry is huge, and it is an investment that does not see any return.

It may not be possible to succeed, but it may not be successful, and the situation of opening five or five is too cost-effective for the current security zone.

Smiling slightly, Xu Yuan looked into Su Hongtao's eyes and said slowly: "This world is no longer the world we are familiar with, it is impossible to adapt to this wasteland with the past ideas, whether it is survival or scientific research, so I need you to use the knowledge and experience you have learned to find a path of aerospace technology suitable for this wasteland." ”

Xu Yuan was very serious, he knew that it was far more difficult to build a space elevator in the wasteland than on the other side of the earth.

Not to mention anything else, there is a world of difference between the two in terms of the danger of the ocean alone, although he has never really been to the beach, but Xu Yuan has heard other people mention it more or less.

Entering the deep sea, the danger level of the radiation beast will increase exponentially, you must know that only on the battlefield of the earth, the nuclear, biological and chemical weapons that can hit the homeland in wartime only account for a small part of the total launch

So where did the rest of the weapons go? Intercepted, of course, at the surface of the sea.

Under the interference of multiple factors such as viruses, bacteria, and radiation, the mutation of marine organisms is far more elusive than that of terrestrial organisms, but the base of the space elevator must be built at sea, at sea along the equatorial line.

"You've really got a problem for me, an old man." Su Hongtao suddenly said with a wry smile.

Xu Yuan was silent, just staring into his eyes.

After a moment of silence, Su Hongtao took a deep breath and said, "Can you give me a general direction?" What kind of space technology do you need to focus on? ”

After thinking for a moment, the corners of Xu Yuan's mouth curved, "I need you to invent a rocket and launch it into low earth orbit or synchronous orbit, no matter what method you use, I need you to get me the good things flying in the sky, and then repair it and shoot it again." ”

After speaking, Xu Yuan didn't give Su Hongtao a chance to say anything else, but got up directly and said: "Do it well, I believe you can do it, but first, you have to make a gadget for me first, it should be very simple for you, it is the small rocket that is launched in a foolish way, I need you to help me get four out of it, which will be used to launch communication satellites, you don't have to worry about space junk or anything, just make it and it can run." ”
