"Okay!" With a move of the system elf, a faint and transparent film of light appeared around Wu Jin's body.

The invincible aperture is that you are invincible, and no one will defeat yourself, of course, it is also an unknown number to defeat others, so if you want to defeat others, you must become stronger.

"This is the invincible aperture!" Wu Jin felt that there was no change in his body, just a thin film.

"It's not what the invincible aperture is, I don't believe you go out for a walk, provoke a random person, and let someone else beat you to try!"

Wu Jin pouted, did he have a pit in his head, why did he provoke others?

If there are really those people who don't open their eyes to provoke themselves, of course they don't mind trying the effect of this invincible aperture.

"Well, I still have a little bit of a good person, what do you think you can exchange?" Wu Jin asked as he looked at the picture.

The system elf shook his head, he originally wanted to see the effect, but since he couldn't see it, forget it.

"What do you need now, a good person can only buy basic exchanges, these basic exchanges are helpful to you, it is recommended that you have the ability to buy them all!But you still choose the one you need the most in the end!"

Wu Jin glanced at it casually, there were probably hundreds, and there were many more, but he didn't look at it either.

"Well, this is a martial arts synthesizer, and this exercise synthesizer, and this elixir synthesizer, and this, this is actually a weapon synthesizer....!" Wu Jin screamed again and again when he saw one, these things were something he dared not think of.

Take the martial arts synthesizer as an example, the above is only a level, you can synthesize low-cost martial arts, you only need to take two martial arts and put them in the synthesizer, and a new martial art can immediately appear, of course, this martial art is still low-level, but the advantages of the two are combined together, so this is also a new martial art.

In this way, as long as you want to learn the martial arts you want to learn, you can synthesize them, and the power of the synthesized martial arts is much better than the previous ones.

The most important thing is that this martial arts synthesizer can be upgraded, and then you can put more advanced martial arts and more martial arts synthesis.

It can be said that this is a product of the sky.

Wu Jinzhen didn't know who created this system, and there was such a powerful thing.

Not only that, but there are a lot of good things besides martial arts synthesizers.

These are all in the basic exchange, and this basic exchange is so powerful, so what about the rest of the exchanges in the lower rows?

Wouldn't that be even more powerful?

Wu Jin didn't dare to imagine it.

"You see if there is a basic exchange for synthetic weapons, this shop needs to be operated, and it also needs to make money!" Wu Jin swallowed, he didn't dare to look down, he was afraid that he couldn't help but buy things that he didn't need for the time being.

Now he needs to run this shop, which used to be a weapon dealer, so just exchange it for one that can make weapons.

The system elf nodded, he glanced at the picture, and after a few seconds, he stretched out his hand and waved, and three images appeared in front of Wu Jin.

The first is like a coffee table, with several round grooves on it and a neat panel at the back.

This thing is called a weapon crafting table, and it can be used to place ingredients in a circular slot, and then the weapon will appear on the board.

The second is a big furnace, and the introduction is that this is a weapon synthesis furnace, and the effect is the same as that of a martial arts synthesizer.

The third is a large furnace, behind the furnace is a forging table, with a hammer, fixture or something, this is manual forging, and the first two are automatic forging.

After looking at the three pictures, Wu Jin felt that the first one was better, after all, as long as the materials were put in, the weapon would automatically come out.

The other two, one requires a weapon to use, and the other has to do it yourself.

Wu Jin thinks that it is more ideal to be a lazy person.

"Just pick the first one!" Wu Jin said softly.

The system elf nodded, and when he was about to do something, he suddenly said: "I still have to make it clear to you about this thing, the one you choose is called the weapon making table, which can automatically make weapons, but there is a disadvantage, that is, you must have drawings, and detailed drawings, otherwise he will not work!"

Wu Jin frowned when he heard this, this is a drawing, he hurriedly asked, "How did you get the drawings?"

"You can buy it for a good person, or you can do your own research, anyway, as long as you have detailed drawings, you can make weapons, if you really don't have drawings, it is recommended that you exchange for a weapon forging table, this can be made regardless of whether you have drawings or not!" said the system elf, pointing to the last picture.

Wu Jin thought about it, and finally decided to exchange the first one, first of all, he didn't know how to forge, and secondly, he didn't dare to be interested in forging.

"Alright!" With a wave of the system elf's hand, a brand-new weapon crafting table appeared in Wu Jin's mind.

"Why don't you take it out?" Wu Jin looked at the system elf suspiciously.

The system elf shrugged helplessly: "You didn't say to take it out, besides, this weapon crafting table can be used here, isn't it the same wherever it is placed?"

"Oh!" Wu Jin nodded, I see, so that he can make weapons anytime and anywhere in the future.

"Well, this weapon crafting table also comes with three drawings, one is a short sword, one is a knife, and a broad axe!" said the system elf with some novelty.

"There are three more drawings?" Wu Jin was a little happy, and hurriedly asked, "What materials are needed for these!"

"Well, these require iron ore and wood! you can find some to try!" said the system elf.

Wu Jin nodded, he remembered where he saw some raw materials in the warehouse just now, and there were some ores or something in them.

He hurriedly walked to the warehouse, rummaged in it for a while, and finally found a pile of iron ore and some wood.

"How can I give it to you!" Wu Jin suddenly thought that he had no way to give the system elf.

"Haha, look at me!" With a wave of the system elf's hand, a small pile of things suddenly disappeared in front of Wu Jin, and then looked at the appearance in Wu Jin's mind.

Without waiting for Wu Jin's command, the system elf picked up the ore and wood and put them in the round trough, and then he chose the short sword on the panel.

The panel display time takes five seconds.

"Can you make a weapon in five seconds?" Wu Jin's heart thumped, if it was really that fast, then he could make a fortune by selling weapons.

"Of course, if you are willing to spend ten good guy points, you can also add a production slot, how about it, do you want to earn some good guy points, so that you can be strong, powerful, infinitely powerful!" the system elf tempted.

Shouldn't this upgrade also need good people, right?,How to upgrade, you need ten good people to start.,Isn't there a cheap one?

"No, if you don't want to open one more slot, just build them one by one!" the system elf shrugged.

Five seconds passed, and a three-inch-long short sword appeared in the hands of the system elf.
