My world double door

"Under the current radiation pollution, the available resources are too scarce. The materials used for this basic medicine are almost all stuck at the usable standard point, and the effect is far inferior to the medicine before the nuclear pollution with abundant resources. Such a bottle of medicine I Want to be very collectible!”

The man pointed at the potion that the woman took out and introduced it to the drone with saliva. After he finished speaking, the woman next to him also followed suit.

"The materials of these two medicines are very pure. They do not contain any radiation-contaminated raw materials, so the medicine itself has no side effects when taken, and there will be no body distortion or ulceration. Moreover, the medicine is mild and will not cause any harm to the body. Destruction is a very perfect version.”

After the woman supplemented the man's words, she returned to her timid state and shrank behind the man.

"..."

The man and woman who were eager to introduce their trophies did not know what a surprise their words brought Li Yang.

‘Gene Potion’

‘The body correction medicine can repair 99% of defects without any side effects. ’

‘Nervous reaction potion No. 3, the reaction ability is increased by 30%’

‘The drug is mild and will not cause any damage to the body’

In the gold shop, Li Yang, who was sitting on a chair and watching the video transmitted back to the screen, listened with astonishment to the man and woman's description of the two small bottles of potion, and his heart was full of exclamations.

‘Why does this sound so sci-fi? The biotechnology in this world is so awesome that it can even create such a thing? ’

'How did you do it? ’

‘This guy won’t fool me, will he? ’

With a turmoil in his heart, Li Yang stared straight at the two tubes of potion. He knew that the probability of the other party lying to him was extremely low.

Even if it was a lie, at most the two tubes of medicine were fake, and the information the other party said could not be false.

After all, they don’t know that they are not from this world. Since the other party assumes that everyone has the same source of information and world view, it is impossible to make up some universally known information.

So...there really is such a magical thing in this world.

‘It’s developed. ’

Li Yang's heart moved silently, and then he thought of the time mentioned by the other party, and an inexplicable look flashed in his expression - this world has been at the end of the world for fifteen years, that is 2086...

With thoughts swirling in his mind, Li Yang looked at the two people standing on the top of the building on the screen, with a flash of thought in his expression.

This kind of thing doesn't seem to be of great value in this world, otherwise the other party wouldn't trade it so casually.

In this case... I have to get it over and take a look!

After thinking about it, Li Yang unilaterally muted his voice, took several deep breaths to stay calm, and finally turned on the microphone.

"It looks good, so what do you want to exchange it for?"

Li Yang spoke slowly with some interest but not in a loud tone, staring at the other person's expression through the screen.

"There is no need to meet in person to trade. I have a few gadgets here. If you are willing, we can trade through drones."

Li Yang said nonchalantly, but his heart was beating fast.

On the rooftop, hearing the sound coming from the drone's horn, the fawning smile on the man's face became more and more obvious.

"We don't want anything in particular. If you think it's suitable, why not tell us what you're willing to exchange for, and we can make a decision."

What to exchange for?

Li Yang looked at the two people in the video frame and couldn't help but frown. He subconsciously thought of the one hundred and twenty tables and a bunch of bits and pieces in this building that he had just moved back to the private house. He shook his head again.

Although his intuition told him that those things must be good things, the problem was...he didn't even know what they were called, how could he trade them?

In this case, what can be used to trade with them?

Li Yang rubbed his eyebrows. The only thing he could think of was food.

‘Those in power use iron pots to cook food with less pollution. ’

‘In this world, food that has not been contaminated may be very precious? ’

Li Yang thought for a while and decided to test it out.

But if it's very precious...what kind of weight should be set?

"Since it is a small collection that cannot be used, there is no need to spend a lot of money. I have three boxes of uncontaminated cans here, absolutely zero pollution. I wonder if you are interested."

The food on earth should be pure food for them, right?

Li Yang controlled his voice and spoke slowly, watching the movements of the two of them closely.

"Canned food, then this..."

Hearing Li Yang's words, the man in the video responded subconsciously at first, and then suddenly froze, with a flash of astonishment in his eyes: "You, what did you say?"

Too much to say...

Li Yang keenly noticed that not only the man, but also the woman next to the man looked shocked, and felt very frustrated.

But fortunately, there is still a chance to remedy the situation.

"A box of cans that have not been contaminated, zero contamination, do you want to replace it?"

Li Yang's voice was calm.

This is what you asked yourself.

"No contaminated cans!"

A flash of disbelief flashed across the man's expression, and then turned into eagerness and tears: "Brother, wasn't there three boxes just now? Why did it suddenly become one box?"

"There's only one box, and it's up to you whether to exchange it or not."

Li Yang didn't change his expression, just paying attention to the movements of the man and woman on the screen.

"Change, let's change!"

When the man heard this, he and the woman immediately shook their fists excitedly. Li Yang suddenly felt that they seemed to have made a lot of money...

Forget it, he has kept the quantity of this stuff to a minimum, just one box.

"But brother, can you check the remnants of that thing for us first? If that's the case, it won't be too late to exchange it. Please forgive me. We, the evolutionaries at the bottom, have never seen such a good thing. This is After all, we worked hard to find these things in the laboratory, so we can’t believe it easily.”

After the man finished the exchange, he carefully spoke to the drone's camera. Li Yang could see his expression clearly through the screen.

"Wait."

Li Yang said something, then left the apocalyptic world with a flicker of his body and came to a private house in the suburbs of Heyang City in the real world.

He quickly walked to the table next to the living room, took out a hiking bag he had brought, took out a box of canned beef, and then took out an empty plastic box with nothing printed on it.

Opening the steel-stamped can, he poured all the contents into the plastic box, and used a small plastic bag to put some of the residue inside the tin box. Li Yang went to take out the second drone. Taking this box of cans and the residue in the plastic bag, I returned to the post-apocalyptic world.

He tied the small plastic remnants to the second drone and controlled it to take off in the same way, flying towards the place where a man and a woman were.

"The residue has been transported, please accept it as soon as possible."

Li Yang spoke in a calm voice to the first drone remote control. The man in the video nodded repeatedly and raised his hands to take off the plastic bag from the drone flying overhead. Then the woman next to him immediately took out a scan Yi looked at the residue.

Li Yang clearly watched the scanner start up. Some unfamiliar symbols lit up, but the index was always 0.

A man and a woman looked up at each other in shock and surprise.
