Wen Wan sneezed.

Rubbing his itchy nose, he began to pick and choose from the stall again. On the stalls, there was nothing of value, most of them were useless dirt and stones.

Moreover, the stall owner is still dark, and the asking price is too high. A piece of clay costs three hundred taels of silver, and I don't know if it has a hole in my brain.

Moreover, there is one with a hole in the brain.

Wen Wan glanced at the excited Rong Bai helplessly. What is so good about these soils, looking at the performance of Rong Bai, it is like picking up gold.

"Can't it be cheaper?" Wen Wan asked the seller.

The seller is a little girl, not very old, and does not look more than sixteen years old. The body is very thin, but the two eyes are unusually bright.

"It can't be cheaper. The little girl tilted her head: "It's the price of cabbage, you still want to be cheaper, why don't I give it to you directly?"

Wen Wan looked at the lump of mud, she didn't want this thing to give her!

Glancing at Wen Wan, the little girl turned her head disdainfully, and then stared at Rong Bai who was squatting on the ground. She could see that Rong Bai was very serious about choosing.

After waiting for a long time, Rong Bai finally made a decision: "This piece, this piece, this piece, I want it." ”

After speaking, he reluctantly looked at the rest. She also wants the rest, but the rest of the things will not be used for a while. Even if you want to use it, it doesn't necessarily have a technical use.

Wen Wan turned around, restraining herself from looking at Rong Bai, who paid the bill.

On the other side, the little girl who took Rong Baizi did not put the clod of soil up. Instead, he stared at Rong Bai for a while: "Nine hundred taels of silver, buy three pieces of soil?"

"Didn't you sell it at that price? Rong Bai replied: "Besides, I can use it." ”

"Can you use this too?" the little girl reluctantly pointed to one of the three clods that Rong Bai had chosen. "Ordinary people don't need this. ”

Rong Bai was stunned.

She chose three pieces, two of which were to be used to make medical equipment, and the remaining one was intended to be used to make artificial leg bones.

Wen Wan didn't look down on these mediocre-looking clods, because they didn't seem to be worth anything at all. However, as a master of weapon forging, Rong Bai definitely has more than that.

These clods of soil in front of him are not simple clods of soil, in Rong Bai's era, these are things that everyone loots. Whether it's a weapon or armor, as long as you add a little bit of this thing, it will have a better nature.

As for the first piece Rong Bai picked, it was the best material for making artificial bones. Not much, as long as one-tenth of the size, it is enough to make a clear leg bone.

"I'll use it. After returning to his countenance, he picked up the piece.

She can't make the seller regret it.

"These are all smelted by me. Before Rong Bai could say no, the little girl said, "Seventeen rare earths are seventeen different elements. This is the highest purity I can come up with so far. ”

Rong Bai put the rare earth in his hand into a bag.

"Ahem, if you have a lab that can use these things, I can contribute to the purification. At this time, Wen Wan was also stunned.

What kind of treasure is this?

"Rare earth elements, you should know how much this world contains, although I don't have many of these, but they can't be extracted casually. ”

As she spoke, the little girl raised her head and looked at Rong Bai: "Don't you want to know about these rare earth mining areas?"

Rong Bai shook his head honestly.

Rong Bai is not a greedy person, for her, it is good that the resources are enough. These things in his hands can already meet everything Rong Bai needs.

The little girl was helpless.

With difficulty, he got up and sorted the remaining clods into bags.

"These things are useful?" Wen Wan suddenly said.

She was a discerning businessman, and she had heard of rare earth elements, but they were only used in highly skilled industries. According to the level of development of this world, this kind of thing can't be purified.

However, since Rong Bai is so optimistic about these things, could it be that this inconspicuous soil is really very pure?

"Of course it works!" replied the little girl. In the next second, I coughed for a long time without breathing, and only after relieving myself did I speak: "These things, when added to normal materials, can greatly improve the various properties of materials. ”

At this point, the little girl's face turned a little paler.

Rong Bai frowned, this little girl's body didn't seem to be very good.

"If you don't have the technology you are using, I can provide it. The little girl gasped.

"I'm going to use it, I have the technology myself. Rong Bai replied. The technology of people in this era, Rong Bai does not believe it. Just look at everything in the world by artificial, to what extent can it be used.

Don't wait until the end, the high-purity rare earths that you just encountered by luck are over.

"Do you have technology?" the little girl looked at Rong Bai in disbelief: "How can you have technology! At the technical level of this era, it is impossible to develop the technology of using rare earth elements!"

This era!

Rong Bai has heard this word many times and said it many times.

Wen Wan was also stunned.

Seeing the expressions of the two, the little girl was also stunned.

"So, you're not from this era?" the three asked in unison.

Now it's a lot of fun. Rong Bai felt that this world was just a sieve. It is already a miracle to be able to find Xiao Heng, and to meet a gentle one again, it is a miracle of miracles.

Now, the little girl in front of me is also wearing it.

It's a miracle!

After asking this, the little girl looked at Wen Wan and Rong Bai, and suddenly laughed.

"I said how could anyone take a fancy to rare earths, it turns out that you are just like me. The little girl's acceptance seems to be higher than that of Rong Bai and Wen Wan.

"Aren't you afraid?" Rong Bai couldn't help but ask. Such a supernatural thing, why is the little girl so receptive?

"Why are you afraid?" the little girl asked rhetorically.

Rong Bai couldn't answer.

Anyway, she is not afraid, she was blown up in her previous life, and in this life, she earns one more day, not to mention, she is still living so wonderful and happy now.

"Isn't it time travel? ”

Isn't it time travel?

Rong Bai's whole person is not good.

The gentleness on one side is not much better.

At that time, Rong Bai already had an existence that could control the space. Space powerhouses are extremely powerful in terms of combat effectiveness and comprehensive ability.

However, no one can control time.

If only it could be controlled, it would be nice to send everyone back to the pre-apocalyptic times.

The gentleness on the other side is even more confused.

Time travel, that is an existence that can only appear in fantasy. There is even such a thing as a time paradox in the mouths of scientists.

"Don't you understand?" the little girl scratched her hair: "It doesn't matter if you don't understand, anyway, you know, as long as you have enough technology, time and space are not a problem." ”
