Everyone is fleeing the famine, my items can be upgraded

Can only materials with hardness no more than three be printed?

Yang Yuan has seen the hardness table representative of materials before.

That is:

If the hardness of talc is one, then the hardness of gypsum is two, calcite is three, fluorite is four, apatite is five, feldspar is six, quartz is seven, topaz is eight, corundum is nine, and diamond is ten .

From this point of view, the hardness of these three points is really basic enough, and it is estimated that even ordinary metal cannot be printed.

Yang Yuan had expected this. Anyway, he had no intention of using the basic version to print high-quality materials.

The engineer next to him said: "It has been assembled. If you have any other questions later, you can call me. If you need any drawings, you only need to have someone draw one and input it. The parts will be automatically analyzed and the materials can be printed out. But This basic version of the 3D printer cannot print precision parts such as chips, and the hardness of the material should not exceed three points, otherwise it will easily malfunction."

"Okay, I'll remember it, thank you." Yang Yuan thanked him.

"This is my job."

The engineer smiled, said goodbye and left.

After the engineer left, Yang Yuan immediately opened the basic drawings that came with the printer.

These drawings are all small toys, such as Ultraman, Iron Man, and even Jingle Cat.

But these things are all integral and are drawings put in for testing. Under normal circumstances, no one would use a 3D printer to print such cheap things.

However, Yang Yuan didn't mind it. He grabbed a large handful of rotten leaves from the ground and put them into the material bin. Then he selected Jingle Cat and started printing.

Just listen to the printer buzzing.

After the buzzing sound ended, there was another 'swish' sound.

About a minute later, a gray-black fist-sized jingle cat appeared at the discharge port.

Yang Yuan picked up the doll Jingle Cat and took a look at it. Not to mention, it was quite exquisite, with every detail printed out.

If sold on Earth before integrating into this world, such exquisite dolls would cost at least hundreds of dollars each.

[3D Printer Lv.1: 1/40 (not upgradeable)]

"So the way this printer gains experience is by printing a little bit of experience at a time?"

Yang Yuan smiled slightly, and then directly set up the printing of thirty-nine jingle cats.

After setting up the program, he kept putting rotten leaves into the material bin, treating the garbage as materials.

Anyway, it’s just to gain experience and the number of times you gain it, it doesn’t require any quality.

"Wow……"

"ah!!"

“So cool!!”

Suddenly cheers came from the factory gate.

The six little girls who were called by the soldiers came. The youngest was only five or six years old, and the oldest was only about nine years old.

As soon as they entered the radiation range of the cooler, they looked in disbelief because they didn't know how long it had been since they had been so cool.

"Give them two more clothes and a quilt, and put them all in the account. They feel cool now, but they will feel cold later."

Yang Yuan said to the soldier who brought the people over.

"OK."

The soldier nodded. Anyway, after the high temperature and water problems were suddenly solved, and they were stuck here and couldn't do anything, those of them who couldn't go out were all free, and now they were very manpower-rich.

Nowadays, except for the superpowers who have broken through the limit at least once, everyone else will be roasted directly as long as they leave the safe zone.

Soon, the six little girls, who either lost their relatives or were separated from their relatives, moved into the three small compartments of the safe house and began to gain experience in the safe house.

And Yang Yuan was not idle here either. After he filled the material warehouse with rotten leaves, he picked up a dead branch and picked up all the rotten leaves in the entire factory. These were his raw materials.

Storm, who had white hair and white eyes, watched this scene from a distance, wondering in her heart, how could the layer of rotten leaves that can be seen everywhere be used as material?

Is that guy trying to cut corners?

Is this too blatant?

However, she only knew that her superiors were going to place an order from Yang Yuan, but she didn't know what the order was. Therefore, she didn't try to expose Yang Yuan's suspected behavior of cutting corners, so she continued to maintain her cold persona and stayed there. Be the needle of the wind god.

Soon, more than half an hour passed, and all the thirty-nine jingle cats that had been set were printed out.

Yang Yuan came to the printer and saw that he had full experience, so he upgraded directly.

Because this 3D printer is a quick and rough job, there is no dyeing at all. Everything is still the color of the raw materials, giving people a drastic feel.

With the upgrade, visible to the naked eye, the printer's outer shell has become more refined.

Soon, the upgrade was completed and the experience data became:

[3D Printer Lv.2: 0/80 (Basic 3D printer, capable of printing items with material hardness no more than 4; cannot be upgraded)]

Yang Yuan smiled slightly.

Other people's machines become worse and worse with more use, but your own machines become stronger with more use.

I think it won't take long for this printer to be able to print any material.

By then, the speed at which you can gain experience will definitely increase greatly.

This time, he directly set 340 jingle cats, ready to upgrade to level four in one go when he got all the experience.

If he wasn't worried about machine failure, he would have set the number in the thousands.

It is worth mentioning that after upgrading to Level 2, the printer's working efficiency has improved a bit and the printing speed has accelerated a bit.

At this time, Zhao Jiayan came back with Jiang Yiyi, and behind them there was a group of people helping to carry things.

Zhao Jiayan did buy a lot of things, but as she was used to saving, she was still reluctant to spend a lot of money. She only spent three human-level spirit cores.

What surprised her was that one human-level spirit core was worth a hundred ordinary spirit cores.

In other words, she spent 300 ordinary spirit cores during this outing, and she had never been so lavish.

However, after Yang Yuan looked at the things he bought, he was a little dissatisfied: "Why are they all daily necessities? There should be a lot of good things in this safe zone, right? For example, you can improve your strength. Your strength is too weak. If there is something that can improve your strength, The best thing is to buy more, and there are snacks, don’t you girls like snacks?”

Zhao Jiayan said dumbfounded: "No matter how extravagant the safety zone is, we won't waste food and make snacks under such circumstances, right?"

"Okay, anyway, don't be too frugal. We keep too much money for no use. We have earned it so hard, and if we don't spend it ruthlessly, we will be sorry for ourselves."

As Yang Yuan spoke, he took out a few jingle cats from the printer and handed them to Jiang Yiyi: "Yiyi, these are toys for you."

Jiang Yiyi's eyes lit up and she happily took it: "Thank you, big brother."

Apparently she does like Tinker Bell cats, even the non-dyed ones.

"There are many more toys like this. There are six children in the safe house. You can take them and play with them."

Yang Yuan touched the little girl's head. The reason why he only wanted a little girl before was to find a playmate for Jiang Yiyi, so that the little girl would not develop character defects if she did not play with her peers for a long time.

"You actually even considered this." Zhao Jiayan said in surprise.

Yang Yuan smiled. He was not a person who had been struggling in this world for three years, but someone who had just traveled through time. Many times, his way of looking at problems was different from others.

Hearing this, Jiang Yiyi walked to the door of the safe house with the Jingle Cat doll and looked at the six children inside.

The six little girls also looked at her eagerly, of course, mainly looking at the Jingle Cat doll in her hand. They obviously wanted it very much, but they didn't dare to take the initiative to speak.

[Please give me monthly votes, please recommend votes! 】

There were many inexplicable people who actually said that my recommendation votes were faked. I was really speechless. There were also some very speechless comments. Some people made comments that I didn’t even know existed. I thought the other person was. The boss came and was ready to discuss it with him, but when he went to see his homepage, he found that he had been registered for more than a thousand days, but he was still an ordinary user, not even an ordinary member.

Therefore, we have set up a limit on speech, just a certain threshold of fan value. I believe that as long as people who really speak seriously will not care about this threshold.

Another point is that I will read book reviews very seriously, but writing book reviews will make my mentality explode, and it will easily make me not in the mood to write. Therefore, I will delete those book reviews after reading them carefully, and I am not interested in the people who posted the book reviews. If you have any opinions, I would like to apologize here.

Thank you very much for your support!
