When I looked at the robot, I saw a pile of gold lying there. It was the gold that I saw Chen Fan and Baihan trading.

"I wonder if you can send me something like that?" The robot said, looking at the pile of gold.

Hearing this, Chen Fan did not refuse, and sent some gold to the past.

After the robot takes the gold, it disappears from the screen.

Seeing that the robot left without saying a word, Chen Fan stood in place and didn't know what to do.

After a few breaths, the robot's face appeared on the screen again, but this time the eyes on his face flashed from time to time, and said: "I just checked and found that the thing in my hand actually contains a special substance, which can be very useful to us, but this material is very rare, only less than 1%!" ”

"Gold?"

Chen Fan said. But soon he shook his head and said secretly: "If it is gold, it will not be only 1%, it should be something else!" ”

Suddenly, Chen Fan thought of something and said, "Robot, can you purify the gold?" ”

"Gold?"

Hearing Chen Fan's words, the robot looked puzzled.

Seeing the robot's confused appearance, Chen Fan immediately explained: "It's the thing in your hand, about 75% of the substance!" ”

"Oh!"

Hearing Chen Fan's words, the robot suddenly said, "The substance you said is useless at all!" ”

"It's useless to you, but it's very useful to me!" Chen Fan muttered in his heart, but he didn't say it, explaining: "That kind of substance is very popular in our plane! ”

Hearing this, the robot nodded and didn't say anything more, just when Chen Fan lost his mind, a light flashed not far away, and he saw a machine-like thing appear in front of Chen Fan's eyes.

"What's that?"

Looking at the machine on the table, Chen Fanleng paused, looked at the robot and asked.

"This is the purification instrument we invented here, as long as you put things on it, then it can help you purify all kinds of substances!" The robot explained.

Hearing the robot's words, Chen Fan's eyes lit up and asked, "How to use it?" ”

"As long as you put the gold in that instrument, it will automatically analyze how much substance there is, and then you can press purification!" The robot said.

Hearing the robot's explanation, Chen Fan put the gold in his hand into the machine, and sure enough, when the gold was just put into the machine, an analysis chart appeared in front of him.

A piece of yellow stuff accounted for 75%, and there were other substances that occupied some, and finally Chen Fan saw that 1% of the matter existed.

Seeing the substance on the instrument, Chen Fan asked the robot, "What is the function of this substance?" ”

"This kind of substance is called X matter in our place, and it exists like energy, which is very rare!" The robot explained, "If you can always provide this substance, then we can take the development of the plane to the next level!" ”

Hearing the robot's explanation, Chen Fan nodded, and then pressed to purify, but when purifying the gold, it was not completely purified, but a trace of slag remained on it.

Of course, the reason why I did this was not too amazing, if the purity of the gold was raised too high, it would arouse suspicion, so Chen Fan turned the purity of the gold into 24K, which is 99.99% as the saying goes, so that the value of the gold in Chen Fan's hands can be greatly improved.

Putting the matter of gold aside, Chen Fan's eyes were attracted by another card slot in the instrument, because there was a faint substance in this card slot. That is, the X substance in the robot's mouth.

Gently touch it on substance X with your finger, and sure enough, a thin layer of powder appears on your finger.

For about half an hour, Chen Fan wiped the sweat from his forehead, and all the gold that he had originally traded with Baihan had been purified.

"Robot, is there enough X matter in this?"

In Chen Fan's hand there was a small wine glass, which was filled with powder, all of which were substance X purified from gold.

"Enough! That's enough! ”

Seeing the cup in Chen Fan's hand, the robot hurriedly nodded and said, "The X substance in this is enough for me to use for a few years!" By the way, don't know what you need? ”

Hearing the robot's words, Chen Fan suddenly asked, "By the way, do you have any microrobots in this plane?" ”

"Absolutely!"

Hearing Chen Fan's request, the robot nodded and said, "We have many microrobots here, I don't know what type you need?" ”

"Are there some who have the ability to detect, as well as the ability to attack, and the most important thing is that they are concealed, and they cannot be detected!" Chen Fan said.

Hearing Chen Fan's request, the robot said with a smile: "Don't worry, the micro robots we invented are very powerful!" ”

As he spoke, the robot raised his hand slightly and said, "Look at this miniature robot!" ”

"Huh?"

Hearing the robot's words, Chen Fan's eyes looked at the robot's palm, there was nothing, but since the robot said that, there must be something.

Chen Fan said: "I didn't see anything!" ”

"This is the nanobot we have here, and it's impossible to see it with the naked eye!" As he spoke, a black dot appeared in the robot's palm, and gradually, a small thing appeared.

"This is what you call a nanobot?" Seeing the nanobot in the palm of the robot's hand, Chen Fan asked.

"Not bad!"

The robot nodded and said, "There is a special liquid in this nanobot, and just one nanometer is enough to stun an adult!" ”

Hearing the robot's words, a smile suddenly appeared on Chen Fan's face, "Teleport over!" ”

"I have a lot of other microrobots in my hands, I'll send you some if you need them!"

"Good!"

Hearing the robot's words, Chen Fan nodded.

Sure enough, it didn't take long for all kinds of robots to appear not far from Chen Fan, some were as tall as people, some were like mice, and the most peculiar thing was that a robot was as soft as flowing water.

"Smack!"

Chen Fan put it in the palm of his hand, and then slapped it hard, making a crisp sound.

"What kind of robot is this?" Seeing the lump of things on the ground, Chen Fan asked.

"This is a flowing water robot, I specially invented it for you, as long as you cover it, then it can form a barrier to protect you!" The robot explained, "With reference to the information of your plane, unless it is a weapon such as a missile, you don't need to be afraid!" ”

"Wouldn't I be invulnerable!"

Hearing the robot's words, Chen Fan was stunned for a moment, and then muttered: "In this case, as long as I don't die, then I won't die!" ”
