The brightness of the space has increased; to give an example, what used to be only a sliver of light has now become a watt.

I glanced at the time; it was 7:20.

Rong Department Store integrates wholesale and retail and opens early.

Zuo Ling quickly took a shower, ate two donkey meat sandwiches and a bowl of donkey meat soup, and hurried to Rong Department Store.

Upon entering the lobby of Rong Department Store, I was immediately drawn to the products advertised on the giant screen.

Portable biodegradable toilet!

The screen is demonstrating how a toilet works.

The biodegradable toilet is half the size of a regular toilet, and includes a clean water tank, a biodegradant storage chamber, and a urine purification and circulation system.

The principle is that after urination or defecation, the booster pump flushes the waste into the sewage chamber.

The degradation agent is poured in and undergoes high-temperature chemical treatment with the waste to form fertilizer that can be used for crops, which is then placed in the fertilizer chamber.

The water in the urine is purified and then recycled into a clean water tank, reducing water consumption.

The theory sounds good, but whether it can achieve the effects it claims... I haven't used it, so I don't know.

The price is not cheap, at several yuan, and even more expensive is the degradation agent used with it.

A male staff member in a suit and glasses walked over:

"Madam, are you interested in our company's portable biodegradable toilet? Would you like me to introduce it to you?"

"Of course I'm interested. It sounds great, but I don't know if it can achieve the effect you're talking about."

Portable biodegradable toilet, so practical!

In a post-apocalyptic world with no water or electricity, it's easy to imagine how terrible the toilet problem would be.

Having such a product with you is an essential item for improving the quality of life in the apocalypse.

The toilets I bought before are nothing compared to this one.

Those things can only be solved with plastic bags, not to mention the smell they have to endure.

Recycling bags means no need to take out the trash or smell the stench—it sounds wonderful!

The only inconvenience is that biodegradable toilets require electricity.

However, this is not a problem for Zuo Ling.

The staff were friendly and approachable.

"Your concerns are also the concerns of many customers. If you are willing, you can test it yourself. It takes 2 to 3 hours for the degradation agent to break down the excrement into fertilizer."

Zuo Ling: "..."

I have patience, but I'm not thick-skinned enough!

To urinate or defecate in public... Oh my god!

The staff member pointed to one side of the booth:

"We have a testing room over there. To make it easy for everyone to see the disassembly process clearly, the back of the toilet is completely transparent..."

After walking around the trial room, I found that the back of the trial room was right next to the toilet's water tank.

You can't be seen using the toilet, but the exhibit is made too clear; the back of the toilet is made of completely transparent tempered glass.

Once inside, you can probably see clearly what's inside the bag and what's being eaten.

As more and more people gathered, the staff announced, "Anyone who wants to try it out can come and give it a shot."

Everyone was embarrassed!

Let everyone watch your burden turn into fertilizer? Who has the audacity to do that?

One clever person suggested, "If anyone has children, give it a try."

Child: We may be small, but we have dignity too!

Someone said to the staff member, "Why don't you give it a try?"

The staff, having seen this scene many times before, gave a wry smile.

"I really want to try it for you all, but I'm afraid you'll accuse me of cheating, then it would be a waste of time."

That makes sense; the back half of the trial room is transparent, while the front half is not visible.

Who knows what the staff are doing inside!

To ensure a good shopping experience for everyone, Rong Department Store has well-maintained restrooms on each floor, so no one is in a hurry to use the toilets.

Even if someone tries it, it's best to wear a larger size for the best effect.

The small size doesn't even have enough skin, let alone the large size.

For a time, a stalemate ensued.
