Speaking of metal materials.

There are many medical devices in Yin Youyue's system, as well as various surgical tools, such as hemostats, tweezers, scissors and the like.

What's more, she now has a variety of vehicles in her system, and she can remove countless kinds of metal from a single ship.

These metal materials, after being reforged, can naturally be made into a variety of better weapons.

But Yin Youyue felt that this would be a waste, if he could buy all kinds of metals directly in the system, it would be perfect.

Yin Youyue didn't immediately tell Qu Qianqian about this, she planned to go to the system to find it first, maybe there would be metal materials!

When he arrived in his room, Yin Youyue opened the system and looked for the commodity column for raw materials purchased from the system mall, but unfortunately these things did not appear on it.

She saw the search bar again, so she searched for the word metal, but what appeared was a variety of metal products that had been finished, such as needles, scalpels, medical equipment and boats, because the goods were arranged from low to high by price, and there were no metal materials to sell in front, which means that there is no metal sold in this system mall.

Do you really want to buy a multi-million-point cruise ship and remove all the metal?

This is too wasteful, and the existence of such a large cruise ship does not have a suitable fuse tool, which is very wasteful!

There are only many small items that can be purchased for re-forging.

Just when Yin Youyue was thinking like this, she suddenly thought of an inquiry bar that she had used before.

After asking a question, a solution can usually be found.

Yin Youyue hurriedly wrote down her question: How to buy ready-made metal materials that do not exist in this world?

As soon as this question was raised, there was an automatic reply.

There are three ways to do it, the first is to work hard to earn enough points, upgrade the system, open the raw material mall, and you can buy any materials you need!

The second is to buy existing items made of the required metal in the system mall and dismantle them for use.

The third is to post requirements in the taskbar, like other planes to buy the required metals.

When Yin Youyue saw the third type, her eyes suddenly lit up, could this plane be able to communicate with other worlds?

Her previous idea of designing medical systems was based on the principles that exist in countless parallel universes.

Parallel universes represent the existence of countless worlds, including ancient worlds, medieval worlds, and even immortal cultivators, modern ones, interstellar ones, and so on.

The four-dimensional space theory is that in the four-dimensional space, the interconnection of various worlds can be realized, and through a medium point, any thing needed for existence can be obtained!

This idea coincides with the third answer today.

The plane is the name of every world!

Seeing this answer, Yin Youyue even doubted that in the future, when the system was upgraded to a certain level, she might be able to travel through time and space through the system, go to other worlds, or even go back to the past or to the future!

Yin Youyue couldn't help but wonder, if her ideas were true, would she be able to return to her original world?!

Thinking of this, Yin Youyue's breathing was very short.

If the system can do this, it is no longer an artifact that can explain it, it is simply the most powerful existence that manipulates all universes.

Yin Youyue didn't think that she was so strong, and she could even make such a thing against the sky.

She is even very skeptical about how the medical system came about, and she has not yet made the system into shape.

Yin Youyue didn't choose to entangle herself, but asked the system directly:

"The medicine system, do you know who created you?"

【Drop! The host identity permission is too low to be known at this time. 】

Yin Youyue frowned, her current system has only been upgraded once, and it is normal that she has no right to know.

Seeing this, she simply asked:

"At what level do I have to be to know who created you? What level am I at? ”

[The host is now a low-level second-level host, and it needs to reach a high-level ten-level host.] 】

Inferior secondary hosts?

If she is upgraded once, she is rated as level two, so wouldn't it take nine upgrades to reach level ten?

Upgraded before, because the total points accumulated reached 10 million, so it was able to be upgraded to level 2.

Now Yin Youyue took a look at her total accumulated points, a total of more than 18 million points, and seeing that it was about to reach 20 million, she couldn't help but look forward to it in her heart, when the total points accumulated reached 20 million, would she be able to upgrade again?!

Although Yin Youyue was looking forward to it in her heart, the most important thing now was that things about the plane needed to be explored clearly.

Yin Youyue continued to ask the system:

"How do I publish a task on the taskbar?"

After Yin Youyue finished speaking, the system automatically popped up a task bar, and she saw that there were tasks on it.

She clicked on a random one to watch, that is, what spaceship to buy, what spirit grass and even strange tasks such as buying life-sustaining pills, the amount has private chats, and there are also direct amounts written in the amount, and the amounts on it are basically tens of millions to hundreds of millions of system coins, and there is even a new calculation unit, crystal coins!

Seeing this unit of calculation, Yin Youyue naturally asked, how many system coins does this crystal coin represent.

[One crystal coin is equal to 100 million system coins.] 】

Yin Youyue saw that what was the life-sustaining pill that lasted for ten years, and the price marked was five crystal coins, that is, five billion system coins.

Is this something that the average person can afford!!

Yin Youyue felt that he was afraid that he would have to save these five crystal coins for a lifetime before he could afford a life-sustaining pill that could last for ten years.

So it seems to be worth it!

must live for ten years, in Yin Youyue's cognition, no amount of money can buy it!

But now that it appears in the taskbar, it means that there really is such a thing, so someone will ask for it.

Wait a minute!

Yin Youyue looked at the dozens of pages of content on it, and the nicknames of the tasks posted on it were all different, and suddenly gasped, and asked in disbelief:

"The system, these people who publish tasks, are they all people who have a medical system like me?!"

Could it be that she is not the only person who has a system, and the entire universe has countless such existences hidden?

[The host understands incorrectly, each plane has a system, but different systems inevitably have different functions, and this medical system is a unique existence. 】

As soon as Yin Youyue heard this, she understood that there was only one medical system, and the other hosts should have other types of systems.

Yin Youyue was proud and proud that she didn't hear the tone of the medical system.

She saw that at the bottom of the taskbar, there was a button to publish the task, so she clicked on it, and sure enough, there was a title, and the task requirements, and the remuneration to be filled.

Yin Youyue tried to release the demand for twenty catties of high-carbon steel, and in terms of remuneration, he wrote a hundred system coins.
