The black thing floated in the air without any weight. Because I had never seen anything in the dark world, I could not be sure what it was. Li Dachuan and Fairy Linggui twisted their heads at an angle of 180 degrees with the flying thing, watched the thing fall to the ground. This action was actually very funny, but the sect leader and the sect leader of the Dachuan Sect did not feel it at all.

The object fell to the ground without making any loud noise. When Li Dachuan looked at it, he realized that it was a black animal skin. The furry animal skin was as dark as ink, and his whole body revealed a mysterious aura. It didn't seem that the fur of any known animal, nor did he know whether it was pulled from a tiger in the dark world or a wild boar. In short, the space for imagination is very huge.

"Dachuan, look... there seems to be something wrapped in the middle of this fur." ​​Fairy Ling Turtle said, pointing to the slightly bulging fur in the middle.

Li Dachuan took a look and said casually: "It's probably the apple you fell to the ground before, right? It flew lightly, like a feather, not like it was wrapped in something?" Although he said this in his mouth, he still walked over and lifted the animal skin from the ground. It had no weight, and it felt like he was grabbing a feather. The fur left the ground, and a black egg entered his sight. The size of a fist, the shape of an oval, looked very strange.

"Is this egg... an egg from the dark world?" Fairy Ling Turtle was stunned for a while before saying something came out.

A sanitary tampon actually exchanged for a magical fur that was as light as a bed sheet, and an egg was worn on it. The guy opposite the Gate of Hell was too excited? Or was he a natural businessman, and after making a big profit, he gave him some small gifts, and then looked forward to the next transaction?

"I think... that sanitary gauze can always solve the pain of a woman bleeding every month in the dark world? Will he dedicate that sanitary gauze to a queen of the dark world and easily obtain a general position or something?" Li Dachuan's mind was already a little confused.

"What are you saying? It's dirty!" The fairy of the Spirit Turtle slapped Li Dachuan on the back of the head. This time she used a little force, which made the boy who was talking nonsense suddenly feel pain.

In fact, using one piece can solve problems with far away and always plug the leaks. Not to mention in the dark world, even in the world in front of you, it is definitely a great invention that shocks the world. There is absolutely no problem with achieving and wealth surpassing Bill Gates. The Spirit Turtle Fairy is a woman, and she knows that it is impossible. So she still punished this slap for a reason.

At this moment, the ink-like egg automatically floated up and stuck to the black fur again. This change made Li Dachuan and the Linggui Fairy confused. Both of them had hundreds of guesses in their minds, but none of them were reliable.

Huh! Another thing was thrown out in the black light vortex. This time it was a piece of paper.

Li Dachuan took the paper that had not yet landed. It was strange. It was completely different from the paper here. It was of black background and white. Looking around, he saw a monster with a duck head and human body on it. There were some words written on it, obviously trying to explain something. But both of them were illiterate.

"What does he want to tell us?" Li Dachuan said.

"I want to know too. You draw a picture and ask him what he wants to say. We don't understand each other's language. This is a way to communicate." said the Spirit Turtle Fairy.

One word woke up the dreamer. Li Dachuan then took a large stack of paper and a neutral pen and started painting. He drew a piece of fur and an egg on the paper, then drew a big question mark next to it, and then kneaded it into a ball and threw it into a black light vortex.

Soon, another piece of black paper flew out, and a duck-headed monster was drawn with white and red paint strokes. He dyed his fingernails and his lips red. He put the underwear on his head, and the bathroom was pressed on his forehead. This look is a standard psychopathic style in the world here, but his feeling seems to be very good. In the painting, he put on a very cool style.

Fortunately, I haven't eaten for more than a month, otherwise Li Dachuan would have spit out all Dingxi in his stomach. He quickly drew another picture with a question mark. Then, pieces of paper flew across the gate of Hell, one after another, and one after another.

It is impossible to fully understand the other party after one elimination. However, from the other party's special description, Li Dachuan still grasped some useful information. Among them is about the fur and the strange egg. The fur was pulled out from a pig-like spirit beast in the dark world, not the tiger skin or mouse skin he imagined. As for the egg, it was also the pig's egg.

That guy was indeed a bit of a profiteer, and he exchanged pig skin and eggs for the sanitary sanitary syringe under Comrade Liu Qing's name. But what is unexpected is that in the dark world, the number and variety of spirit beasts will be so abundant, and even pigs will lay eggs.

It was magical, but Li Dachuan still felt amused and laughed.

The last picture that flew out from the black light vortex was a picture of a duck-headed monster leaving with his arms swinging. However, he drew the content of the picture that he had come to exchange for the next two days. Before leaving, he threw out another thing. It was actually a book about learning languages ​​in the dark world. There were pictures and words on it, which didn't look very difficult to learn.

"That guy is really smart. Next time I exchange with him, I will also give him a few books, such as Chinese dictionary, children's reading pictures and reading literacy, etc. I understand the language of the dark world, and he understands our Chinese, so it will be easier for us to communicate." After saying goodbye to the duck-headed guy in the form of pictures, Li Dachuan said thoughtfully.

"I agree with this. If you always communicate in the form of pictures, I will almost be tortured by you." Fairy Linggui said unhappily. She had been helping Li Dachuan to sort out the paper thrown by the other party, and gave Li Dachuan some translation opinions based on the content of the picture above. At this time, her gaze suddenly fell on a picture that seemed to have been ignored, and it was difficult to move away.

"Sister Gui, what did you find?" Li Dachuan leaned over.

After a while, the Spirit Turtle Fairy said, "See, did he say that no matter what it is, once he leaves that world, he cannot return. By the same token, once the things on our side enter the dark world, they cannot return. That is equivalent to an assimilation effect, right?"

Li Dachuan frowned and looked for a while, "I think... he seems to have another meaning to stand inside. He seems to want to tell us that once things are exchanged, they will not be returned or exchanged, right?"

In fact, there is the meaning that the Spirit Turtle Fairy understands, and it also means that Li Dachuan understands. This discovery made Li Dachuan and Spirit Turtle Fairy a little grateful. Fortunately, they did not rashly enter the dark world at that time. The game that never returns is not something that every player likes, nor is it an adventure that every explorer can bear.

A barter transaction ended here, but Li Dachuan didn't even understand what the other party was and how he happened to meet him, but he got several treasures from that world in a daze. No matter what, he made a profit.

After carefully recalling the entire bartering transaction process, he also found that what he regarded as a treasure is actually nothing in the dark world, it is just some simple and ordinary goods. But the simple and ordinary goods on his side are quite rare treasures for the dark world. This is really an interesting thing.

After the transaction ended, the opened door of hell was closed, and he returned to his original appearance.

"If you want to open the gate of hell in three days, Sister Turtle... do I have to sacrifice something?"

"Of course, it's the same every time." said the Spirit Turtle Fairy, "That's a spell. If you use it once, you can't care for your whole life, right?"

Li Dachuan looked at the Spirit Turtle Fairy blankly, and then subconsciously touched the bare head. His heart was in a mess, and he was thinking that it was impossible for his hair to grow out in three days. The only hair he could use was there. Fortunately, it was quite dense...

After cleaning up and sorting it out, Li Dachuan and the Spirit Turtle Fairy left the cave. It took more than a month to complete two things. One was to use the Tongqiao Mother Pill to improve the spiritual power cultivation to the end of the middle stage of the Vajra Realm, and the other was to successfully open the gate of hell and successfully complete a barter transaction. Although the entire transaction process was so strange.

On the way back to Aoki Village, Li Dachuan was also thinking about a question silently, that is, the WL organization that also opened the parallel door. Do they also use this bartering method to exchange? Or, just send some people in. Although they cannot return, they can provide some more valuable things to this side?

Judging from some things that have happened, the resources obtained by the WL organization from the parallel world are not pig skins and pig eggs, but they are all shocking technology. Therefore, this conjecture is still very likely to be valid.

However, he was not jealous or discouraged. After all, the WL organization is a huge organization, and the time he has mastered the parallel gate is far more than he has. How could he hope to have the achievements of the WL organization in the first transaction? As long as he is given enough time, after he masters the language of the dark world and understands the dark world, he can do it!
