[7519.94 gold found, is it recovered?]

Li Kang pressed one hand on a pile of gold, and a system prompt immediately came to his mind.

[Isn't it right? How does the system calculate it?] Li Kang looked unhappy and felt that he had been cheated again.

Eighty-four catties of gold, converted to 8400 gold, where did the remaining 900 points go?

[System, you explain it to me clearly!]

[The purity of gold is not enough, the average gold content is 75%. 】

Uh, Li Kang was a little embarrassed, and the dare system sent back mercy and gave a little more?

[Eighty-four catties of gold are made in the Ming system, and each catty is 596.82 grams. 】

[Recovery!] Li Kang hurriedly ordered, ashamed of his naivety.

Eighty-four pounds of gold sounds like a lot, but the volume is small, almost a cubic meter.

After collecting the gold, Li Kang was extremely bored, picking and picking among the strange-shaped gems, and at the same time, he was not greedy enough to expect a surprise to appear.

Li Kang fumbled for the stone while paying attention to the system information, for fear of missing something.

[Discover the energy block.] Is it converted to energy?】

I'll just say that good people have good rewards!]

Li Kang happily played with the energy block in his hand, which was a palm-sized translucent hard stone, irregular in shape, pale white, and very beautiful. Li Kang believes that even if it is useless, it must be worth a lot.

[I don't know what ingredients it is made of.] 】

Li Kang deliberately pinched it hard, but there was no response, and he didn't even get any dandruff. Li Kang didn't believe in evil, and the force in his hand became bigger and bigger, and in the end, he even used his internal force, but he still couldn't do anything about it.

"Shhhh Is it so hard?" You must know that it is a piece of iron, and Li Kang can easily press the fingerprint. Sure enough, none of this occult stuff is ordinary.

Although he is a little obsessive-compulsive, Li Kang will not drill the tip of the horns, he will be hard, no matter why it is, as long as it can bring benefits to himself.

Denying the conversion in his heart, Li Kang put the energy block in his hand aside alone, and at the same time quickly checked the other six similar stones one by one, and then he was satisfied with the seven energy blocks together, and admired them carefully, and felt that ... Beauty, more beautiful than diamonds, he can't bear to do it.

Distressedly, he picked out the smallest piece of it in his pocket, and Li Kang looked at them affectionately for the last time.

[Let's convert.] 】

There was no vision, no 'ding dong', and the six energy blocks disappeared silently in place, as if they had never appeared.

[Convert to gain energy 62.] 】

The result made Li Kang very satisfied, a piece of about ten points is a hundred times better than about ten pieces.

When the opening is auspicious, it is natural to take advantage of the victory to pursue. Touching one stone after another, a third of it was touched in a blink of an eye, about twenty or so pieces were identified as useless things, in addition to being beautiful, there is no use value, ah, it can't be said that, it can be used to add a little halo in the future, labeled, what "royal tribute", "mermaid's tears" and the like, it is very suitable to deceive the local tyrants.

Finally, when Li Kang touched the twenty-fifth stone, the system reacted.

[Coal gangue was found.] The host is eligible to redeem "cement" and its crafting process. Cement: 2 gold or 1 energy/ton, manufacturing process: 20 gold or 10 energy. 】

"Cement?" Li Kang's eyes lit up like a light bulb, and he called the system intimate.

As for the question of "what was found was coal gangue, why was it cement that was unlocked", Li Kang said that he was disdainful of asking, with his understanding of the system, there must be a correlation between the two, maybe coal gangue can be used as a raw material for cement.

Besides, it's okay to have cement, why do you care so much, he's not a scientist.

It's just that this time the system directly set the price of cement, and there was no word "value varies according to type", and Li Kang was slightly disappointed.

After getting along for such a long time, even if Li Kang is unintentional, he can summarize some system rules.

For example, animals can only be exchanged for living animals, and unlocked non-biological products can only be exchanged for finished products, not raw materials (fortunately, the system classifies cement as an industrial finished product, not an industrial raw material). The unlocked plants are not taboo.

For example, whenever a new product is unlocked, if there is a text that says "value varies by kind", it means that all the types of the product can be redeemed as long as you can think of. If the price is determined by the system, then there is no choice, and the system will automatically choose a similar product for you, which is not good or bad.

Just like the cement this time, it must be just ordinary cement, and the performance of earthquake, compression, waterproof and other aspects will not be too slagty, but don't expect it to be good.

However, the "series" of the system is absolutely guaranteed, and the quality is not said, throwing off the tofu scum eight streets.

With the unexpected gain of cement, and then looking at the gray coal gangue in his hand, Li Kang suddenly had a different feeling, [The artifact is obscure, how can the ugly coat cover its high-quality inside?]

If this disgusting emotion is heard by the EPA officials who are worried about the accumulation of coal gangue, do you think Li Kang will be torn apart by the car, or Ling Chi?

Li Kang didn't care what others thought, he also felt that the praise of coal gangue was not enough, but he had eaten less ink, and only thought of that sentence.

The reason why Li Kang has a soft spot for coal gangue is because of its hidden value, as mentioned earlier, cement is just an unexpected joy, you must know that coal gangue is an accessory product of coal mines!

What Li Kang really cares about is coal mines, not coal gangue!

The fact that the natives were able to pick up the gangue shows that the coal mine is very likely to be open-pit, which is very interesting.

Of course, there is no urgency in this matter now. You need to think long-term.

The gangue matter came to an end, Li Kang was in a good mood, and then his hands touching the stones were much lighter.

Twenty-sixth, twenty-seventh, twenty-eighth...

Forty-seven!

It's a green stone all over.

[Malachite was found.] The host is eligible to redeem "Malachite Crafts". Malachite crafts: value varies depending on the species. 】

The corners of Li Kang's mouth went up, twitching and twitching, trying not to let himself laugh.

Like coal gangue, Li Kang is interested in the associated ore of malachite, copper ore.

Compared with coal gangue, malachite's appearance simply makes the former ashamed to the point of suicide. Li Kang no longer has to tell lies with his conscience, he can boast well.

Even if there is no associated copper mine, the value of malachite itself is also very expensive, not only beautiful handicrafts, but also skin care can be worn regularly!

Forty-eighth, forty-ninth, fiftieth...

Fifty-third block.

[Trace amounts of gold-bearing pegmatites were discovered.] The gold content is 0.0081%, is it recycled?]

[Not recycled!]

Li Kang suppressed the excitement in his heart, reached out and touched the next piece...

[Discover granite.] The host is eligible to redeem "Granite Sculptures". Granite sculptures: value varies by kind. 】

Li Kang grinned and continued to touch the stone.

Fifty-five, fifty-sixth, fifty-seventh, fifty-eighth...

[Magnetite discovered.] The host qualifies for the "iron-making blast furnace" and its construction process. Ironmaking blast furnace: 50 gold or 25 energy per seat, construction process 20 gold or 10 energy. 】

Li Kang silently put away the blue indigo stone, and then touched the stone.

Fifty-ninth, sixtieth, sixty-one... The sixty-fifth, sixty-sixth, and the last.

[Cassiterite was found.] Eligible to exchange for "Pewter". Pewter: Value varies depending on the species. 】

After touching the stone, all that was left were bird feathers, animal skins, animal teeth, animal horns, animal bones, shells and the like, Li Kang took a cursory glance, lacking interest.

So far, in addition to popularizing the "Thirty-six Styles of Forging Body" in the army, no subordinates have been rewarded, and these miscellaneous items are piled up in the hall to obstruct the view, which can be used as part of the reward.
