All realms have enabled me to achieve the Great Dao.

Zhou Yongcheng arrived at the zombie territory, randomly grabbed a zombie, and took out a crystal from its brain.

He discovered that the zombie crystal core contained soul power and life power, which could be absorbed for cultivation. In particular, for cultivators, this was a treasure that could increase the power of their primordial spirit.

In any world, the only thing that can be directly used to enhance one's primordial spirit is the soul.

Those evil cultivators like to massacre cities and collect souls and life force to cultivate, because plundering is the fastest way to progress, while cultivating step by step is very slow unless you have cultivation resources.

However, the zombie crystal cores were useless to Zhou Yongcheng because his primordial spirit level had already transformed into the immortal level. These mortal-level items were useless to him. It's not that they were useless, but rather that they were of negligible value. Even if he eliminated all the zombies in the world and used their crystal cores for cultivation, he might not be able to improve even a little bit.

Although it's useless to him, it can be used for Lü Su's cultivation. This kind of thing is very rare, and there may not be such a world again in the future.

Zhou Yongcheng came to the sky above the city again, glanced at the city below, and asked Hong Hou.

What is this city lacking?

He plans to open a shop here to trade these crystal cores. Although he could directly eliminate all the zombies, there's no need for that, because crystal cores are also very important to the people of this world. Some powerful individuals use crystal cores for cultivation, and they also need them to create gene optimization drugs. He can't afford to deplete their resources.

"The most scarce resources are grain, vegetables, and fruit. Due to the limited land, this city produces very little grain, and only the strong can afford to eat grain, vegetables, and fruit."

Zhou Yongcheng understood: anything that can be grown in the soil is in short supply.

"What about the meat? Can we eat the meat of those strange beasts?"

"It's edible, and quite nutritious. Let me see their test data. The nutritional value of the alien beast meat in this world is about the same as that of the beef and mutton raised in the villages of the real world. Of course, this is only the lowest grade of alien beast meat. If it is high-grade alien beast meat, it should be not much different from the meat of giant beasts in the unknown world."

Zhou Yongcheng hadn't expected the meat of the exotic beast to be so valuable. But thinking about it, it made sense; the exotic beast had evolved and its life level was different.

Back in the real world, Lü Su was watching a video on her phone. After telling her, Zhou Yongcheng drove to the fruit wholesale market, parked the car, and went into the market.

It's around March now, and there are still many kinds of fruit available. Zhou Yongcheng estimates that many fruits have been stored away and are only being sold now.

We arrived at a store that wholesales apples and pears.

The boss was a woman in her thirties, slightly overweight, who looked like she was there to do manual labor.

She was also surprised to see Zhou Yongcheng, after all, people wearing long robes and having long hair were still rare in this era, and you would only see them in hand.

"Boss, do you want to buy apples or pears wholesale?"

"How much does it cost?"

"Apples are 5.2 yuan a pound, and pears are 6.3 yuan a pound."

Zhou Yongcheng nodded, took out his phone, pointed it at the apple and pear, and quickly gave a price.

Wholesale prices are slightly higher; apples sell for less than two to three yuan at the production site, and pears for between three and four yuan.

Zhou Yongcheng pondered whether he should go to the production area to purchase goods. If he went to the production area, he could raise the price a little to increase the income of the fruit farmers. However, this would take a lot of time. Besides, he wouldn't be selling things in the future post-apocalyptic world for a long time. At most, he would collect enough crystal cores and then he wouldn't go to that world.

I'll just buy it here.

"I'll take all the apples and pears you have here, just make sure the price is right," Zhou Yongcheng said.

The proprietress glanced at Zhou Yongcheng, considered for a moment, and said, "If it's all the same, then it's 50 cents less."

“Okay, just send it to the warehouse in Huanbei, delivery and unloading included,” Zhou Yongcheng asked.

"For Huanbei, delivery and unloading are included."

The proprietress made a phone call, and a truck arrived shortly afterward.

"Boss lady, you just unloaded the goods yesterday, and you're hauling more today?" the driver asked with a smile.

"No, a big boss came today, and all the goods were sold out." The proprietress was also very happy.

"The proprietress is quite lucky."

Then the proprietress had the driver weigh the car and let Zhou Yongcheng see its weight. She then weighed a basket and let Zhou Yongcheng see its weight. After that, several people came to load the car.

The six-meter-long truck was loaded with a whole load of apples, half of which were apples. After the apples were loaded, they were weighed again to subtract the weight of the baskets and get the weight of the apples. Then the pears were loaded, and after that, another round of operations was carried out.

There were more than eight tons in total, and Zhou Yongcheng paid him about 100,000 yuan.

Zhou Yongcheng and his driver arrived at the warehouse to unload the goods.

Over the next few days, Zhou Yongcheng went on a shopping spree at the fruit wholesale market, and the fruit wholesale market knew that a big customer had arrived.

One day, a truckload of oranges arrived and was being unloaded when Zhou Yongcheng saw it and bought them immediately. The owner was stunned; in all his years in business, this was the first time he had ever seen his goods sell out so quickly.

So Zhou Yongcheng asked them if they had any fruit arriving tomorrow, and they didn't need to unload it; he would come and collect it. Unfortunately, only two families had fruit arriving tomorrow: one truckload of bananas and one truckload of grapes.

After spending about a week in the real world, Zhou Yongcheng felt that he had sold enough fruit, so he stopped going to the fruit market to buy more.

They started purchasing grains, such as rice, flour, potatoes, and sweet potatoes. These were easy to buy; Zhou Yongcheng would buy 100 tons each time, simply by calling to arrange delivery.

That day, Zhou Yongcheng was busy with procurement matters when Hong Hou reported that the research center had successfully developed carbon nanomaterials and had already manufactured finished products.

"What are carbon nanomaterials?" Zhou Yongcheng asked.

"Carbon nanomaterials should have a wide range of applications. For example, carbon nanomaterials are used to manufacture high-energy batteries and carbon-based chips. In the future, many devices such as computers will use carbon nanomaterials. The emergence of carbon nanomaterials is equivalent to the beginning of a new era."

"Is it really that exaggerated?" Zhou Yongcheng was somewhat surprised.

"It's that exaggerated. If it weren't for the owner, Blue Star would have to wait many more years to research and manufacture real carbon nanomaterials, let alone apply them."

“I never imagined that carbon nanomaterials could be so important. Does our country have any factories that can manufacture carbon nanomaterials?” Zhou Yongcheng asked.

"No, the equipment for producing carbon nanomaterials can only be manufactured by Xiao Jiu. Many instruments cannot be manufactured with current technology."

"Are we supposed to open our own factory to produce carbon nanomaterials?" Zhou Yongcheng asked.

"The owner can also produce equipment and sell it to others."

"What's the difference between that and producing it ourselves?"

Zhou Yongcheng pondered for a while. Everyone said that carbon nanomaterials were so important and should have a wide range of applications, and that they could definitely make a lot of money. However, he didn't want to worry about it. After thinking about it, he decided to let Wu Longjiang handle the production of carbon nanomaterials.

Wu Longjiang, who was working, had no idea that another heavy burden was about to fall on his shoulders.

Let's talk about carbon nanomaterials when we get back.
