My world double door

“It’s incredible that such pure food actually exists!”

On the roof, the woman repeatedly used the pollution index tester to test, but the value she obtained was always zero. Her eyes sparkled with excitement, and she couldn't help but speak.

"It has been fifteen years since the end of the world, and more than twenty years have passed including the time of nuclear contamination. This is the first time that I, Sun Er, have seen zero-contamination food!"

The man couldn't help but murmur to himself. The next moment, the excited woman's eyes moved and she suddenly pressed the button in her palm. Then the encrypted message was quickly formed through brain waves and transmitted to the man's brain.

[If it is really pure food, just a can, it can be sold for a very good price back in the city. Two bottles of basic potion, although it is full of energy before the end of the world, is still worth it]

After the message was sent, the man glanced at her, nodded silently, and then looked solemnly at the drone flying ahead.

"Sir, after consideration, we have decided to have this pleasant transaction with you. Look, in order to show our sincerity, we will transfer this bottle of [Neural Response Potion No. 3] to you first."

The man Sun Er glanced vaguely at a place on the roof of the building next door, and then took out one of the two test tubes placed at his feet. The label on it read [Neural Response Potion No. 3], and used a The soft cotton pad was wrapped tightly, and the sealed test tube was tied to the drone.

"…………"

In the gold shop, Li Yang, who was sitting on a chair and watching every move of the man in the handheld video, stared closely at the dark blue potion.

As the man's hand tied with the potion was removed, Li Yang's heartbeat suddenly accelerated. He resisted the urge to immediately control the drone to take off and return. He took a deep breath more than ten times before he felt that his state was somewhat calm.

"In that case, wish us a happy transaction."

Li Yang controlled the drone to return, and at the same time spoke to the controller of the first drone. As soon as he finished speaking, he turned off the microphone here, breathed a sigh of relief, and quickly controlled the drone containing the medicine to return.

In the camera, the man also had a bright smile on his face, and seemed to be looking forward to this transaction.

‘It seems that food that has not been contaminated is indeed very precious in this world. ’

Li Yang's heart moved secretly, and he had a vague sense of danger of being in a polluted environment. However, the attraction of the magical item such as genetic medicine made him temporarily ignore this danger, and his eyes were fixed on the flight path of the second drone. He controlled it in a large circle and returned to the back door of the gold shop where he was.

"Buzz..."

The slight movement of the drone's fan blades made Li Yang's heart beat faster involuntarily. He stood up hurriedly, paused again, and disappeared from the gold shop in a flash. When he came back, he already had three layers of N95 masks on his face, and his hands Also include a pair of thick gloves and a bottle of alcohol spray.

Putting the alcohol spray next to him, he opened the door with his heart beating uncontrollably and looked up. The drone was floating quietly in the empty corridor. A tube-shaped object wrapped in soft cloth under the fuselage instantly came into view.

"Huh~"

Li Yang breathed a sigh of relief, and used his hands wrapped in thick gloves to untie the test tube wrapped in soft cloth, put it in his hand, and immediately turned back to the counter of the gold shop, placing it carefully on the counter.

After thinking about it for a while, he tied the box of cans to the drone and steered it back. At the same time, he stared closely at the surveillance of the first drone, stopped its automatic suspension, and controlled it to fly above the man.

"The can has arrived, and the second tube of potion can be placed on it."

Li Yang turned on the communicator and while speaking, a second drone also appeared above the roof of the building.

"Okay sir, I hope these two bottles of pure basic potions from before the end of the world can put you in a good mood."

The man nodded immediately, with a bright smile on his face, and waved. The woman next to him immediately wrapped the second tube of medicine in a soft cloth and handed it to him. Under Li Yang's gaze through the camera, he tied it to the drone with a rope. .

"Buzz..."

After the bundling of the medicine was completed, the drone immediately took off and returned. Li Yang directly started the automatic return mode, released the control, and controlled the first drone containing the can to slowly descend with his other hand.

It wasn't until the second drone containing the medicine disappeared from the man's sight that the first drone landed at a sufficient height. A man and a woman immediately excitedly unpacked the cans tied to the drone's body. When I came down, I unscrewed the lid and checked it. After confirming that it was all zero-contamination food, I quickly put it into the safety box where the test tubes were previously stored.

"Brother, we are very satisfied with this transaction. To express my gratitude, I will do one more thing for you this time."

After the man confirmed the authenticity of the thing, he immediately said to Li Yang's drone with a smile. After saying that, he watched the drone take off again, smiled at the camera, and then looked sharply at the building next door. He raised his hand and took out his hand from his waist. A strange-looking firearm immediately appeared in his hand. At the same time, he accelerated violently and rushed towards the roof of the building next door like a cheetah.

"Whoosh..."

When the man arrived at the edge of the building, he kicked his feet and jumped across the floor space seven or eight meters away. He landed on the roof of the second building, and then jumped towards a corner of the roof with a strong body.

"Forgive me, I don't mean any harm!"

A thin man, with tattered clothes and dirty clothes, fell from the corner in horror, begging loudly for mercy.

"..."

In the gold shop, before Li Yang received the test tube, he saw the man's fast and violent movements like a cheetah on the return screen, and his eyes widened.

‘My skills are so strong, is this due to long-term training? ’

‘Or... genetic medicine? ’

Li Yang clearly noticed that the man moved very easily across the floor space that was no less than eight meters visually, as if he just jumped across it casually, and after jumping over, he landed in the building opposite, at least two meters away from the edge of the building. s position.

Such a length...the world record for long jump is not that long!

"Forgive me, I don't mean any harm!"

As Li Yang watched, the man's attacking movements became even more vigorous and fierce. A thin man like a homeless man was almost easily controlled by him in the same way as a tiger catching a chicken. Then he held the thin man's neck with one hand and struck again. With one jump, he jumped back to the floor he was on while carrying a human being.

‘There are actually people here. ’

Li Yang frowned.

"This guy who only took the basic resistance potion has been hiding there since we started trading. I don't know what his purpose is. If you are interested, I might as well leave it to you."

Sun Er threw the thin man on the rooftop, smiled and spoke to the drone flying in the air.

"Ahem, adults, please forgive me. I have no ill intentions. I really don't have any ill intentions. I just want to exchange some food with you..."
