After relying on the motherland, my supermarket has become more and more prosperous.

Chapter 291 Star Coins, all 10 Star Coins

Anyone who has tasted filtered water and mineral water knows how to choose between the two.

Bert and Caesar are naturally no exception.

After the two of them drank the mineral water handed to them by Jiang Wanwan, their eyes were completely different when they looked at the shelves displaying the mineral water.

Unexpectedly, in addition to the two interesting goods mentioned above, this small shop opened on the battlefield also has good things like mineral water.

Bert could no longer wait and wanted to go shopping.

However, before shopping, you need to exchange the currency of this shop!

On the way here, Caesar had already explained to Bert in detail the rules for exchanging star coins in the supermarket.

Bert didn't have the energy to look for those low-tech products now, but he brought a lot of low-end materials at Caesar's request.

Bert asked anxiously, "Where can I change currency?"

As soon as these words were spoken, Jiang Wanwan immediately smiled, because she knew that the supermarket upgrade was a sure thing!

Even Caesar, who was standing next to him, looked much more relaxed, and he led Bert directly to the star coin exchanger.

As an interstellar citizen, standing in front of the star coin exchanger, Burt knew the next process without anyone saying anything more.

However, in Jiang Wanwan's eyes, the other party's subsequent exchange process was quite high-tech.

Bert waved his hand and took out a two-meter-tall robot from his space bracelet.

The robot's entire metal skeleton is not covered with anthropomorphic skin, so it can be seen at a glance.

After the robot landed on the ground, its eyes immediately emitted red probing light.

After a quick scan, it finally locked onto Bert, and a mechanical voice rang out: "Master, please give your orders!"

This is the robot from the interstellar world!

Before Jiang Wanwan could observe carefully, she saw Bert taking something out of the space bracelet again.

With a loud 'bang', something fell directly to the ground.

Jiang Wanwan looked in the direction of the sound and saw a cube about fifty centimeters tall and reaching her knees. It was silver-white in color and had a unique metallic luster.

For a moment, I couldn't tell what kind of metal it was.

It doesn't look big, but from the loud noise just now, it seems to be quite heavy.

Then I heard Bert's command: "Move the goods into the exchanger!"

The sentence was a bit brief and the content was not detailed, but the robot received the information very smoothly.

"Okay, master!"

As the mechanical sound fell, the robot bent down smoothly, picked up the silver-white cube on the ground with both hands, and put it into the grid of the star coin exchanger.

However, Bert did not pay attention to the robot. Instead, he looked at Jiang Wanwan and explained.

"These low-end materials are dense and generally heavy, so I brought a robot to help move the materials."

Jiang Wanwan nodded calmly on the surface to show that she understood, but she was screaming wildly in her heart.

This robot that can intelligently recognize context is not a service robot, but a cargo-moving robot?

At this time, the items have been sent into the grid of the star coin exchanger by the robot.

Seeing the screen light up, the three people who were concerned about the price all looked over at the same time.

[One ton of iron blocks were detected, a material used by a Level 10 technological civilization, and can be exchanged for star coins.]

The content of the same message gave them completely different expressions.

Compared to the expressions of surprise and satisfaction on Caesar and Bert's faces, Jiang Wanwan's face was full of shock.

Could that silvery-white metal just now be the iron commonly used on Earth? She really couldn't tell.

Also, that cube that is only about 50 centimeters in size actually weighs one ton?

It was the first time that Jiang Wanwan clearly felt the density of iron.

The most important thing is, one ton of iron can only be exchanged for 10 star coins?

You know, in the primitive world, one pound of iron ore can be exchanged for one star coin.

Even in the underwater world, one ton of seabed ore can be exchanged for 200 star coins!

However, judging from the expressions of the two people next to him, they seem quite satisfied with the price?

Could it be that the value of basic materials in the interstellar world has become so low?

Or do they already have other, more convenient ways to obtain these materials?

For example, the material printer that Xi Ze mentioned before...

Jiang Wanwan's thoughts flashed through her mind, but she didn't speak in a hurry. Instead, she waited for the reactions of the two people next to her.

"Just now you said that a bottle of mineral water costs 10 star coins, right? This is only a ton of iron, but it can actually buy a bottle of mineral water!" Burt's voice was filled with surprise.

Caesar also had a smile on his face, and hurriedly urged: "Hurry, try other materials!"

Hearing this, Bert came back to his senses from his joy and quickly took action.

He took out metallic cubes of different sizes and colors from his space bracelet one after another.

The cubes, with considerable weight, fell to the ground in front of them.

Fortunately, the supermarket floor is durable and dust-free, otherwise the current scene would be unsightly.

As a non-professional, Jiang Wanwan saw so many metal blocks for the first time and naturally couldn't tell what type they were.

However, there was a cube of metal the size of a human head, which shone with dazzling golden light, making people feel particularly jealous and their heartbeats unconsciously quicken.

As Bert took out these things, the robot that had been standing still on the side started working again without anyone saying anything.

The first object the robot bent down and picked up was the golden cube.

Under Jiang Wanwan's gaze, the golden cube was placed into the grid of the star coin exchanger.

The next moment, the screen lit up.

[One ton of gold was detected, a material used by a Level 10 technological civilization, and can be exchanged for star coins.]

Ha, that color and luster just now was indeed gold.

However, is the price of gold actually in the same proportion as that of iron?

How much does a ton of gold cost? I think it's around 10- million RMB, right? And now you can get it for just Star Coins?

Jiang Wanwan didn't have much time to think before the content on the lit screen began to change.

After all, robots will not be lazy when they work.

[One ton of platinum was detected, a material used by a Level 10 technological civilization, and can be exchanged for star coins.]

[One ton of copper was detected, a material used by a Level 10 technological civilization, and can be exchanged for star coins.]

[One ton of titanium was detected, a material used by a Level 10 technological civilization, and can be exchanged for star coins.]

[One ton of chromium was detected, a material used by a Level 10 technological civilization, and can be exchanged for star coins.]

[One ton of material detected, used by a Level 10 technological civilization, redeemable for star coins.]
