Chapter 291 Star Coins, 10 Star Coins

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

Bert and Caesar are no exception.

After they drank the mineral water that Jiang Wanwan handed over, their eyes were completely different when they looked at the shelf where the mineral water was placed.

Unexpectedly, this small shop opened in the battlefield, in addition to the two interesting goods before, actually has such a good thing as mineral water.

Bert couldn't wait to go shopping.

But before shopping, he still needs to exchange the currency of this small shop!

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

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

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

Jiang Wanwan smiled immediately after hearing this, because she knew that the supermarket upgrade was settled!

Even Xize 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, Bert knew the next process without anyone saying anything more.

However, in Jiang Wanwan's eyes, the other party's next exchange process was a bit high-tech.

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

The robot is made of metal skeleton, and it is not covered with humanoid skin, so it can be recognized at a glance.

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

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

This is a robot from the interstellar world!

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

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

Jiang Wanwan looked in the direction of the sound, and saw a cube about 50 cm high and knee-high, silver-white in color, with a unique metallic glow.

For a moment, it was impossible to tell what kind of metal it was.

It looked small in size, but from the loud noise just now, it was heavy.

Then Bert's command was heard: "Move the goods to 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 voice fell, the robot lowered its head and bent its waist very smoothly, picked up the silver-white cube on the ground with both hands, and sent it to the grid of the star coin exchanger.

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

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

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

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

At this time, the items had 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, which are materials used by the second-level technological civilization and can be exchanged for 10 star coins.]

The content of the same message made them have completely different expressions.

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

Was that piece of silvery-white metal just now actually the iron commonly used on Earth? She really didn't see it.

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

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

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

You know, in the primitive world, a pound of iron ore can be exchanged for 1 star coin.

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

However, looking at the expressions of the two people next to him, they seem to be quite satisfied with the price?

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

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

For example, the material printer mentioned by Xize before...

Jiang Wanwan's thoughts flashed through her mind, but she didn't rush to speak, but 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 you can actually buy a bottle of mineral water!" Bert's voice was filled with surprise.

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

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

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

The cubes were heavy and fell on the ground in front of him.

Fortunately, the supermarket floor was durable and dust-free, otherwise the current scene would not be good.

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

However, there was a cube of metal the size of a human head, which shone brightly and made people feel jealous and their heartbeats accelerated.

As Bert took out these things, the robot that had been standing still started working again without anyone telling it.

The first item the robot picked up was the golden cube.

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

The next moment, the screen lit up.

[One ton of gold was detected, which is a material used by the second-level technological civilization and can be exchanged for 10 star coins.]

Ha, the shiny color just now is indeed gold.

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

How much does one ton of gold cost? It seems to be about 200 to 300 million RMB? Now it only costs 10 star coins to get it?

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

After all, robots don't slack off when they work.

[One ton of platinum was detected, which is a material used by the second-level technological civilization. It can be exchanged for 10 star coins. ]

[One ton of copper was detected, which is a material used by the second-level technological civilization. It can be exchanged for 10 star coins. ]

[One ton of titanium was detected, which is a material used by the second-level technological civilization. It can be exchanged for 10 star coins. 】

【One ton of chromium was detected, which is a material used by the second-level technological civilization and can be exchanged for 10 star coins. 】

【One ton of manganese was detected, which is a material used by the second-level technological civilization and can be exchanged for 10 star coins. 】
