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

Chapter 264 Too Bad? No, Too Good

After noticing that Xi Ze had finally come to his senses from the afterglow of the delicious food.

Jiang Wanwan then smiled and began to introduce: "The price of the buns is the same as the Tang sword, 100 star coins each!"

Hearing this, Caesar nodded immediately and agreed seriously: "It's worth it!"

A delicacy as delicious as steamed buns is worth a fortune, not to mention that its raw materials are plants!

"Did you feel any different in your body after eating it?" Jiang Wanwan asked again.

Caesar was stunned when he heard it, then he realized what the other party wanted to ask, and quickly closed his eyes to feel it.

After a while, he opened his eyes, looked a little disappointed, and shook his head.

"I didn't feel it. Maybe it was too short, or the change was too slight. I'll ask the butler to use the medical procedure to scan it again when I get back!"

Hearing this, Jiang Wanwan felt a little disappointed, but she quickly adjusted herself.

After all, even if the buns don’t have any other special effects, their taste alone is already very attractive to interstellar people.

"Now that the three types of goods have been introduced, do you want anything? You can bring the items you want to exchange!" Jiang Wanwan said as she walked towards the cashier.

Caesar followed, looking hesitant.

Logically speaking, there would be plants for sale here in a few days, so he should leave all his belongings and money here and wait to buy the plants.

But the buns just now were so tempting that he couldn't help but want to buy a few more.

Caesar thought again that before buying plants, he must first find out the currency value in this store and the amount of exchange for items.

Well, then take out an item and try exchanging it. If the money you get is enough to buy buns, then buy them. If not, forget it!

Caesar convinced himself and made the final decision in his heart.

Then, stand in front of the star coin exchanger.

Caesar waved his hand, and a strangely shaped translucent gun-like object appeared out of thin air in his hand.

This familiar scene instantly reminded Jiang Wanwan of a term: space equipment!

Sure enough, high-tech civilization has mastered the technology of storing space mustard seeds and applied it in daily life.

If she could exchange a few of these, Jiang Wanwan would no longer have to rely on the system grid.

"This is my daily weapon, the RN9 laser gun. Its power has weakened after being used for a long time. I was planning to replace it with another one after a while. Can I exchange it with this?" Caesar asked embarrassedly, holding the item in his hand.

Upon hearing this, Jiang Wanwan turned her gaze to the laser gun in the other person's hand.

This is a high-tech laser weapon, its power is immeasurable. If we can bring it back to Earth...

There are laser guns in Jiang Wanwan’s system mall, or even more powerful ones.

But what good is it? I can't bring it back to Earth, so I can only use it in the supermarket in the other world.

Therefore, this machine gun in front of him, whose power has been weakened due to long-term use, is a treasure in Jiang Wanwan's eyes!

Of course, in order to maintain her identity as a person of higher-tech civilization, Jiang Wanwan's inner excitement did not show on her face at all.

She said calmly, "You can put it in and try it. The machine will give you feedback immediately!"

Caesar no longer hesitated and put the laser gun into the grid of the star coin exchanger.

The laser gun shrank above the grid, but there was no surprise on his face, obviously he was used to it.

The things were placed in the grid, and Caesar immediately looked at the screen above nervously.

Next to her, Jiang Wanwan's quick glance revealed her current mood.

However, in such a tense atmosphere, what was shown on the screen surprised the two.

[The laser gun has been detected to contain Level 5 technological civilization technology and cannot be exchanged for star coins!]

Caesar looked at the content displayed above, stunned for a moment, and then asked with disappointment on his face.

"Is it because my laser gun is too bad to be exchanged for star coins?"

At this moment, Jiang Wanwan appeared calm on the surface, but she had been arguing with 007 in her heart for a long time.

"007, what's going on?"

"The host is a Level 2 citizen and can only redeem technology within the Level 3 civilization. The current item is beyond the redemption range!"

"But this was voluntarily exchanged for me by the people of this world!"

Since it's okay to ask Xize about the sixth-level technological civilization, why can't I exchange technology?

"Of course, the host can trade with the humans in this world independently, but any trade items outside the scope cannot be transmitted back to Earth through the system!"

Autonomous trading?

My goodness, if the system doesn’t pay, Jiang Wanwan hasn’t earned a single star coin in this world, so what can she use to trade independently?

Furthermore, if items beyond the trading range cannot be transmitted back to Earth, then why would she trade them here? For her own amusement?

It seems that we can only follow the system's instructions and trade only items from the third-level technological civilization.

But after a change of mind, Jiang Wanwan quickly accepted this rule.

After all, the technology is too high-level even if it is traded back.

The country probably won’t be able to conduct research at the moment, and will ultimately have to proceed step by step from the lowest end!

The only thing we need to worry about is whether in the current sixth-level technological civilization, how much technology below the third-level civilization is retained?

Don’t let them all be eliminated, otherwise it will be difficult for customers to find something to trade!

Jiang Wanwan thought so much, but in fact she was just stunned for a moment.

Hearing the voice and meeting Caesar's anxious gaze, he immediately smiled soothingly.

"It's not that your traded items are too bad, on the contrary, it's that the technology contained in them is too high!"

"Ah?" Caesar didn't understand what the words meant.

By this time, Jiang Wanwan had already thought of a set of words and spoke slowly.

"I'm so sorry, I forgot to tell you in advance that I came to your planet mainly to obtain some technology from the third-level technological civilization!"

"Level 3 technological civilization?" Caesar was like a tape recorder, still not quite understanding what he heard.

"I have a dream. I want to build the largest museum of technological progress, displaying all the technologies from level one to level seven civilizations!"

Jiang Wanwan said the reason she had come up with on the spur of the moment and added more to it.

"Now, the technology of civilizations above level four has been almost collected. I came here mainly to collect technology of level three civilizations. Of course, if you can bring out technology of level two civilizations, I would also be willing to accept it!"

Today's Earth is still far from reaching the top of the second-level technological civilization.

It would be a great thing if we could take this opportunity to collect some of the top technologies of the second-level civilization that have not yet been developed on Earth.

After all, the closer the level of technology obtained is to that of the Earth, the more obvious the help it will be to scientific researchers.

For example, a third-level civilization that is dozens or hundreds of years away from Earth's technology can only be used as a direction and inspiration even if it is brought back.

If you want to research and manufacture it in detail, it will take time and effort!
