Seeing the two approaching the time and space wanderer, he immediately stopped the movements in his hand and said in a very exaggerated tone, "Oh, hello, the residents living in the Wasteland of Doomsday, I am Ning Tao, a time and space wanderer from a parallel world, and I am very happy to know you.

I accidentally discovered your world, and I am sorry for what happened to you.

But let’s talk about the serious business. Are you interested in making a deal?”

The two looked at each other, thinking to themselves, why does this wasteland businessman feel a bit like an NPC in the game?

However, Xia Yu breathed a sigh of relief. He was very familiar with dealing with NPCs.

"Of course, what goods did you bring?"

The man nodded, "I have a lot of good things here, all of which are high-tech technologies from my world. For example, this one, a water source purifier, a technology product that can quickly purify water, so that you can still drink clean water on the doomsday wasteland, with only 300 credit points."

"There is also this one, a handheld microwave generator, which can quickly heat food and can also be used as a weapon when necessary, with only 200 credit points."

The man took off one exquisitely packaged technology products from his car, and while introducing their uses, he felt like a country vendor was selling small goods.

"Credit point? We don't have a credit point. Can we trade with something else?"

"Of course, I'll explain the transaction method later, but I'll talk about it when others expire. There won't be only two of you here."

One after another, players arrived one after another.

From their appearance, it is not difficult to see their respective states.

The best in his condition is undoubtedly the overlord. He is wearing a fur coat, and he is still open in his arms in the cold weather. He is carrying a fire axe. He is shaving his teeth while walking. He seems to have just had a full meal.

Bai Ye looked quite miserable. Although his face was calm, it was obviously much clearer. In addition, he had not put on makeup for many days and looked extremely haggard, but he was still clean.

The mechanic was in a normal state. He lost food yesterday and obviously gave him a serious blow, but considering that he had the chance to change to a battery today, he was very energetic.

Xia Yu was not surprised that Ergouzi did not appear. Maybe he was afraid of being surrounded. He probably would have to wait until everyone else left before he would appear.

What made Xia Yu strange was that this time there was no one else - the leader did not come, and the doctor came to trade alone with a cart.

Seeing that the people were almost here, the strangely dressed wasteland merchant said his previous words again.

All he brought were technological items in parallel time and space, which could undoubtedly provide great convenience in this doomsday wasteland, but everyone present had other ideas. The primary goal now is to survive. There is no need to live as exquisitely as food is the most important thing.

"Is there anything to eat?" asked the Overlord straightforwardly.

"Of course, this is a 'raised' nutrient solution, which only needs a bottle to provide the nutritional consumption of an adult meal, and the price is only 50 credit points."

"Stop talking nonsense. I have seen people like you for too many times. Isn't it just for trash? Tell me what should I buy, gold or jewelry?"

The overlord's straightforwardness made Ning Tao feel a little embarrassed, but Xia Yu couldn't help but be happy. Don't say that the overlord's description of "collecting junk" is really appropriate. They are picking up garbage on the wasteland and collecting things. Isn't that the person who collects junk?

Ning Tao said: "Sorry, I have no interest in gold and jewelry. In our world, these substances have no practical significance. I would rather exchange for something that has scientific research value. Recently, I am conducting a scientific research and writing two papers, "The Impact of Doomsday Wasteland on Biodiversity", and "The Reproduction and Extinction of Species in Harsh Environments".

So I hope to exchange some biological samples with you. Any biological can do it. As long as it is from your world, of course it must be alive. I will evaluate the price based on the rarity and quality of the biological samples. After the stock price, you can use the credit points you exchanged for to buy the products I brought."

Everyone was stunned when they heard this. They all brought gold and jewelry to trade. A wasteland merchant recognized this thing, but unexpectedly, they changed everything they wanted.

Xia Yuxin said biological samples? Where can I get it? How many dead rats are there - and they are even roasted.

Xia Yu asked, "Can you die?"

"Sorry, no, only living creatures have the value of research." Ning Tao said as he looked at his watch, "My spacecraft can only stay in this time and space for three hours, and there are still two hours and 27 minutes left. If you want to trade, please send the biological samples as soon as possible. Once the time comes, I have to leave immediately."

Everyone did not hesitate and immediately took action. Although this matter was a little speechless, they always had to try their best to seize this precious opportunity.

"It's over, this is over, where can we go to find biological samples?" The dragon rider lamented as he walked.

"Stupid, building!" Xia Yu directly expressed his only choice.

It’s not okay to catch fish, mice can’t catch them normally, let alone cockroaches, which can be found in that building.

But it must be captured alive, which is a bit troublesome.

The dragon cavalry also reacted, "Yes, cockroaches!"

The two of them ran quickly outside the building, looking at the black entrance, neither of them shrank. They might have been a little scared before. However, they have been used to various monsters these days, and have experienced hunger and coldness. They have been tempered for a long time and are not so particular. They are really hungry. Xia Yu felt that he could eat cockroaches now, so of course he had to roast them first.

"The old method is to use chicken to pull out the cockroaches, and then we go up and catch them. There is no need to have too many. Just have one or two. Anyway, two of these samples are enough."

"What if the cockroaches attack us?"

"What are you afraid of? Cockroaches have limited attack power. At most, they will break their skin and make some blood. As long as they are not surrounded by a large number of cockroaches, there should be no danger."

Xia Yu said that he had already thrown the chicken in. Soon, cockroaches emerged from the darkness. Perhaps because the weather was too cold, the movement speed of these cockroaches was significantly slower and the number was much smaller. The last time they were too dark, but this time they only had a dozen of them, which looked sparse and deserted. It seemed that even Xiaoqiang could not bear it in this doomsday environment.

"Go!" Xia Yu shouted and rushed into the darkness ahead with the dragon cavalry. Both of them were wearing worn gloves, one carrying a bucket and the other holding a torn coat.

The cockroaches seemed to feel the threat and opened their mouths and soared into the air. However, the cold air made them weak in this rush. Xia Yu grabbed them and threw them directly into the bucket.

The dragon cavalry also rushed to two with his clothes, and the two ran out again.

Although they were fast, the two of them were bitten. Fortunately, the clothes were thick enough and it didn't hurt too much.

The two of them were excited and slapped wildly, knocking all the cockroaches hanging on their bodies to the ground. Although they didn't hurt, they felt uncomfortable. Xia Yu was reluctant to step on them to death. He picked up the bucket again and held it with a pot lid. Listening to the sound of the cockroaches in the bucket constantly scratching the wall of the bucket, Xia Yu had goose bumps.

"Go and take the job quickly."
