The food they're receiving has decreased, and many are worried that if this continues, there might not be any food left. Although they've heard that wood-type abilities can be used for farming, the yield is low. There are so many people in the city, and these lower-class people simply can't buy fresh food, nor do they have the means to do so. The currency now is crystal cores, but where are they going to get crystal cores? These are things you get by killing mutated plants, and can these ordinary people kill them? Besides, not every mutated creature has a crystal core.

Zuo Qingya looked at the half-eaten bread in her hand and ate it in one bite. She had been here for a month. Many people were not getting enough to eat. They only had one meal a day, just bread and water. How could that be enough to fill them up? Many people were so hungry that they were skin and bones.

Modern mutant plants exhibit changes in their traits due to genetic mechanisms such as gene mutation, gene recombination, and chromosome variation. These variations are accompanied by randomness and may be the result of spiritual influence. Natural variation provides the foundation for plant evolution and diversity.

Many plants have changed their properties; some plants that were edible before may now be poisonous. Someone, starving, went outside and pulled up a huge carrot to eat, only to die within a minute of taking a bite.

However, a new superpower has emerged: the ability to identify plant characteristics. These individuals have been protected, and their daily task is to identify plants. With this ability, people have discovered that plant characteristics are random. Even for the same species of plant, if they don't grow from the same root system, each root system must be identified; otherwise, people could die from eating them.

Plants these days are truly bizarre. Some people have eaten plants that have undergone positive mutations, which is quite strange. After eating them, they turned into a pile of poop that even smelled of chocolate. Luckily, this person was in their own room when they ate it, otherwise, they wouldn't even know how they died.

Some people ate a positively mutated wild vegetable that tasted like ham sausage. However, there was only one positively mutated plant, and since he couldn't identify the superpower, he ate a second mutated wild vegetable and died.

Zuo Qingya looked at her rare seeds and fell into deep thought.

"My little darling."

"I am here, host."

"My little darling, if only I could open a shop in real life, I could sell nutrient solution. It doesn't taste like much, but it would keep me full!"

"Host, would you like to open a shop?"

Zuo Qingya nodded, "I have this idea, but I don't know if it will work."

"Sure, host, you can open a shop with just a few points!"

"That little bit? How many points is that?"

"Host, I only want points!"

"?" Zuo Qingya looked at her points. "They even remembered to leave me 1 point?" Zuo Qingya was conflicted.

"Host, you have enough points to open a shop!"

"??? Hehe... I thank you!"

"You're welcome, host."

Zuo Qingya was speechless...

"Host, do you want to open a shop?"

"Open it!"

"Yes, host."

Before long, the system announced something.

"The transaction fee for Zuo Qingya's points has been deducted. You can now activate the icon to start selling goods in real-world transactions."

"Host, the icon has been displayed and can be activated."

"good."

Zuo Qingya clicked the icon button that had just appeared, and the icon lit up. She then began to demonstrate how to list and sell products.

After reading the steps, Zuo Qingya started to change the store name, because the current store name was her real name, and she had to change it, otherwise what if someone found out?

Zuo Qingya stroked her chin: "What's a good name for him?"

"Time-Travel Shop?"

"System Shop?"

"A small general store?"

"Still a post-apocalyptic supplies store?"

Zuo Qingya's thoughts ran wild...

Zuo Qingya wrote down the names of the shops she thought of on a piece of paper, shuffled them, and started choosing.

"A small general store?"

"That's the name we'll use."

After changing the name, she followed the steps to put the nutrient solution in the product listing. The product listing immediately showed a reference price, and Zuo Qingya didn't bother to change the price; she just sold it directly.

The shop is open, but how will it actually sell? Will a shop just appear out of thin air? Or is there some other channel? How will it be delivered? Zuo Qingya was completely baffled.

As she was thinking, Zuo Qingya fell asleep.

The next day, when Zuo Qingya woke up, she heard that a small shop had appeared out of nowhere in the city. It was called the Little General Store and only sold one product: a nutritional drink. It was said that drinking one packet would keep you full for a day and that it was incredibly cheap, and you could buy it with trash.

Zuo Qingya checked her inventory in the system space and found that it had decreased significantly. Looking at the purchase records, she discovered that some people were buying large quantities of nutrient solution. After thinking for a moment, Zuo Qingya decided to limit the purchase to five packs per person per day. Zuo Qingya seemed to have underestimated the purchasing power of the Chinese people. Even with the purchase limit, the nutrient solution quickly sold out.

Zuo Qingya checked her points and found they had increased from 1 to 1004, which was more than she could earn by picking up trash on her own.

Once the product was sold out, Zuo Qingya put the remaining nutrient solution back on the product shelf. With the inventory replenished, the store started selling nutrient solution again.

Now, city residents have stopped weeding and are instead forming teams to collect trash outside the city. Ten pounds of trash can be exchanged for a packet of nutrient solution! Who wouldn't want to go?

But some clever people sold the pulled grass as garbage to shops, and surprisingly, it actually worked. Once people knew about this effect, suddenly, the grass outside the city didn't need to be dealt with; a single packet of nutrient solution could feed a large number of people who worked for free. It was better than working all day and only being able to eat one meal, and even then, they weren't full and didn't have the strength to pull grass.

The small grocery store has no employees, but no one dares to take anything from it. They've already learned their lesson: anyone entering without trash to exchange for goods or with insufficient stock will be given a warning above their head. If they take anything, they'll be given an electric shock. The consequences range from being kicked out of the store to being blacklisted. And it's not just a simple blacklisting; everything in the store becomes unusable, even if someone else buys it for you. What works for someone else, keeping them full for a day, will have absolutely no effect on you.

So, once people tried it out, they became more disciplined, queuing up obediently, exchanging their items, and leaving without daring to look around the shops.

If someone doesn't believe in superstition, there's nothing that can be done; they brought this upon themselves.

Seeing that everyone in the city had some trash in their hands, Zuo Qingya decided not to fall behind and went out of the city to pick up trash as well.
