Seeing the approach of the two, the time and space rover immediately stopped what he was doing, and said in a very pompous tone, "Ah, hello, the inhabitants of the Doomsday Wasteland, I am Ning Tao, a time and space rover from a parallel world, and it is a pleasure to meet you.

I stumbled upon your world, and I'm sorry for what happened to your world.

But let's get down to business, interested in making a deal? ”

The two looked at each other, wondering how this wasteland merchant felt 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 with you?"

The man nodded, "I have a lot of good things here, all of which are high-tech from my world, such as this one, the water purifier, a technology product that can quickly purify the water source, so that you can still drink clean water in the Doomsday Wasteland, for only 300 credits." ”

"And this one, a hand-held microwave generator, can quickly heat up food, and can also be used as a weapon when necessary, for only 200 credits."

The man took the beautifully packaged tech products out of his car and explained their uses, giving the impression of a country vendor selling small goods.

"Credits? We don't have credits, can we trade something else? ”

"Of course, I'll explain the trading method in a moment, but let's wait until the others expire, you won't be the only two of you here."

One after another, the players arrived.

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

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

Bai Ye looked more miserable, although his face was calm, but he obviously lost a lot, plus he didn't put on makeup for many days, he looked unusually haggard, but it was quite clean.

The mechanic is in average condition, and the loss of food yesterday obviously hit him hard, but considering the opportunity to change the battery today, he is also refreshed.

The second dog did not appear, which Xia Yu was not surprised, maybe he was afraid of being surrounded, and it is estimated that he would not appear until everyone else left.

What made Xia Yu strange was that this time there was one less person - the sect 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 repeated what he had said earlier.

What he brought was a parallel time and space technology item, which could undoubtedly provide great convenience in this apocalyptic wasteland, but everyone present had other ideas, everyone's primary goal now was to live, not to live so exquisitely, food was the most important.

"Is there anything to eat?" The Overlord asked bluntly.

"Of course, this is a 'nourishing lot' nutrient solution, which can provide the nutritional consumption of an adult meal with just one bottle, and it costs only 50 credits."

"Don't talk nonsense, I've seen a lot of people like you, don't you just collect rags, tell me what are you going to collect, 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 you say it, the overlord's description of 'collecting rags' is still true and appropriate, they are picking up garbage on the wasteland, and this goods are here to collect things, isn't that just collecting rags.

Ning Tao said: "I'm sorry, I'm not interested in gold and jewelry, in our world, these substances have no practical meaning, I prefer to exchange some scientific research value, recently I am conducting a scientific research, to write two papers, "The Impact of the 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 creature can be, as long as it is from your world, of course it must be alive, I will evaluate it according to the rarity and quality of the biological samples, and after the stock price is exchanged, you can use the exchanged credits to buy these goods I brought. ”

Everyone was dumbfounded when they heard this, they all brought gold and jewelry to trade, and the last wasteland merchant recognized this thing, but he didn't expect that all the things he wanted changed when he changed it.

Xia Yuxin said biological samples? Where's the hell, there are a few dead rats—and they're cooked.

Xia Yu asked, "Is it okay to die?" ”

"Sorry, no, only living creatures have the value of research." Na Ning Tao said and looked at his watch, "My spaceship can only stay in this time and space for three hours, 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 is up, I have to leave immediately." ”

Everyone did not hesitate to hear this, and immediately took action, although this matter was a little speechless, but this precious opportunity must always be seized with all their might.

"It's over, it's over, where are we going to find biological samples?" The dragoon lamented as he walked.

"Stupid, Mansion!" Xia Yu directly said the only choice.

You can't catch fish, you can't catch mice, not to mention now, only cockroaches can be found in that building.

But it has to be captured alive, which is a bit of a problem.

The dragoon also reacted, "That's right, cockroach! ”

The two of them quickly ran to the outside of the building, looking at the entrance of the black hole, neither of them flinched, they may have been a little scared before. But these days, I have seen all kinds of monsters, and I have also experienced hunger and cold, and I have long been tempered and not so particular, I am really hungry, Xia Yu thinks that he can eat the cockroaches now, of course, he has to roast them first.

"The old way, use chicken to lure the cockroaches out, and then we go up and catch them, we don't need too much, just one or two, anyway, two samples are enough."

"What if cockroaches attack us?"

"What are you afraid of, the attack power of cockroaches is limited, at most it will break its skin and produce some blood, as long as it is not surrounded by a large number of cockroaches, there should be no danger."

Xia Yu said that he had thrown the chicken in, and soon, cockroaches came out of the darkness, probably because the weather was too cold, the movement speed of these cockroaches was obviously a lot slower, and the number was much less, the last time the number of black pressure was too many to count, but this time only so a dozen or so came out, it looked sparse and deserted, it seems that even Xiaoqiang is a little unbearable in this apocalyptic environment.

"Up!" Xia Yu shouted, and rushed into the darkness ahead with the dragoon, both wearing shabby gloves, one carrying a bucket and the other holding a tattered coat.

Those cockroaches seemed to sense the threat, and the openers rose into the air, but the cold air made them weak in this burst, and they were grabbed by Xia Yu and thrown directly into the bucket.

The dragoon also pounced on two of them with his clothes, and the two of them ran out again.

Although the action was fast, the two were still bitten, but fortunately, the clothes were thick enough and not too painful.

The two of them were excited to beat wildly, and all the cockroaches hanging on their bodies fell to the ground, although it didn't hurt but the diaphragm responded, Xia Yu was not willing to step on it directly, and picked up the bucket again, buckled it with a pot lid, and listened to the sound of the cockroaches in the bucket constantly scratching the barrel wall, Xia Yu had goosebumps.

"Let's go, hurry up."

PS: I'll be there later.
