It's not that hard to open a hospital in another world, right?

Gretel and Serila were not the only ones who wanted to earn this reward.Archmage Bairbo is also in the team, working hard to help summon the earth element:
Make money!
Make money!
There is such a big laboratory, so many disciples and grandchildren to raise!
Although his current laboratory is still under the teacher's name, it is not always possible to share the teacher's research budget... If he can earn more, have more money, and want to do some experiments that interest him, Make it easy!
He is not one of those elves who eat enough for one person and the whole family is not hungry, spend all day in the big forest, and can't spend the money he has!
Master Bairbo worked hard to summon the earth elements, communicate with the earth elements, and let the earth elements mine lead ore from the veins;
Losia and Anari Linge worked hard to summon the earth elements, communicate with the earth elements, and let the earth elements mine borax from the veins;
Ashe Moonsong took a list and counted with the temple priests one by one to check the quantity of borax and lead lumps that had been brought in before;
Gretel and Cerilla also followed the elder brother to help summon the earth element.Of course, neither Gretel, who specializes in medical treatment, nor Cerilla, who casts spells based on instinct and strength, are not good at summoning. What they can do is:

"Huh... the summoning array is ready... I'll check it again..."

"Huh... the magic configuration is confirmed..."

"Three, two, one, let's go!"

Well, to put it simply, it is to act as an emotionless mental power output machine.Activate the summoning array, summon a random earth element, communicate with it, tell it what to do, and then spend mental power to maintain its existence...

"Ah... so boring..."

After working hard all day, Cerilla couldn't help complaining to Gretel.Gretel was also so bored that one Buddha was born and two ascended to heaven. After thinking about it, he had to find a job for himself:
"Hey, there are so many lead ores...all of them are lead ores, how long will it take to turn into lead lumps... I don't know if throwing lead ores directly into them can achieve the effect of extinguishing the nuclear reaction..."

Is it useful... probably it will be.After all, no matter whether lead appears as a simple substance or as a compound such as white lead or black lead, lead atoms are always there.

As long as the lead atom is present, it should be able to absorb the neutrons emitted by the fission of uranium 235?

However, Gretel No. [-] didn't want to take any chances.Use pure lead if you can, and don't try to be clever.

If the lead mine is really not good, pure lead must be needed, and a lot of lead mines will be passed, wouldn't it be a big mistake?
99 thanks, please don't let anything happen to this trembling!

Second, he didn't want Elder Fahim to work too hard.

Undoubtedly, if 20 tons of pure lead needs to be transported there, at least [-] tons of lead mines must be transported...probably more than that.

How much does it cost to transport from the main material world to the elemental world and back again?Instead of tormenting Elder Fahim, it is better to refine these lead mines at the production end...

But Gretel straightened up and looked around.From the mine to the nearby mountain ridges, fires and smoke were everywhere.It was a smelting field one by one, concentrating their efforts on smelting the lead they needed——

...

The local indigenous people's smelting technology, in all fairness, is indeed unique.They have already learned to use the continuous strong wind on the mountain ridges to replace bellows, blowers and other equipment to increase the heat and complete the smelting.

Even so, the lead that can be extracted is still only a fraction of what they need.

No way, this country's industrial power is so limited, although it is indeed a country that can smelt bronze and use bronze tools, it uses less than [-] tons of lead throughout the year.

The temple and the royal family urgently dispatched and tried their best. Up to now, even one tenth of what they need has not been achieved.

Moreover, Gretel thought about the wood burned by smelting lead, and the destroyed nature... His heart throbbed with pain.

He tugged the chair under him, bringing himself closer to the earth elemental.He picked up a piece of lead ore with his left hand, took out a heavy lead ingot with his right hand, and sent it to the earth element:
To be honest, Gretel knew almost nothing about mining and smelting, and he had no idea what compound this lead ore was.Fortunately, this does not affect his communication with the earth element:
"Please do me a favor, extract all the lead in this ore and turn it into pure lead lumps, is that okay?"

The earth element stretched out two chubby arms, one on each side, and took it.A yellow light flashed between the left and right arms, wriggling and wrapping around the thing Gretel handed over, swallowing it bit by bit.

The yellow light on its body fluctuates softly, and the loess also bulges, shrinks, bulges, and shrinks, slowly swallowing that piece of lead ore and that lead ingot into its stomach.After a while, a muffled voice came from Gretel's consciousness:

"I can do it."

"So... over there, where is that big pile?"

Gretel raised his head, swung his arm vigorously, and drew a circle of Big Boss, pointing to the hill created by Senior Brother Bilbo.The earth element turned around slowly, and the earth-yellow fluctuations spread along the ground, and it took a long time to answer:
"...Yes. It's very tiring. You need to pay more."

"...the reward is no problem!"

Gretel endured the pain in his heart and snorted, and pushed out another plate of gems.The earth element shook his body, touched the gemstone with his arm, and took it back:
"not enough."

"It's just a sample. You purify the whole pile and double it."

"It's still not enough."

……Hey!Don't go too far!Our budget, no, the reward we get from the Sun Kingdom is also limited!Gretel swallowed the words and tried to bargain:

"Hey, can it be a little cheaper?"

"We can't... do this kind of thing, our consumption is very high... there must be enough rewards... rewards... little magician, we like the breath on your body, we are willing to cooperate with you, but work is work... …such a big job, it has to be paid for…”

"May I ask, you earth elements, what is the use of gemstones?"

Gretel asked curiously.He can still understand if energy spar is needed. After all, it consumes such a large amount of energy and needs external energy to make up for it.But what's the use of gems?

These shiny little things?It is small, the quantity is small, and the energy is insufficient. What's the point?Could it be that the earth element also wants to exchange gems for money?

...

The next moment, in the consciousness, a large piece of information came from madness.Gretel had to press the center of his brows, import this information into the meditation core, and sort it out before he understood:
The advanced process of the earth element is the process of constantly refining and improving oneself.In the process, seeing all kinds of gemstones, seeing these rare and different gemstones, has been of great help to them...

"Every gemstone is different! The same kind of gemstone, each one is different! The more we see these hard, bright, and colorful treasures of the earth, the easier it is for us to advance!"

emmm... that makes sense.Gretel thought for a while, then began to dig out the space bag again:
"Actually...the essence of a gemstone...is just a crystal composed of various elements. For example, ruby ​​powder, which we used to make [Eternal Flame], was later confirmed to be replaced by aluminum oxide..."

He pulled out one of the smallest, extremely dull rubies, a tiny bit, less than a gram, of ruby ​​powder sealed in a paper packet, and a similar amount of aluminum oxide powder.

Demonstrated one by one, and then handed the ruby ​​powder, alumina powder and aluminum ingots to the earth element.This time, the earth element was silent for a longer time, and then suddenly stretched out his arm and put it on his hand:

[In other words, reading aloud and listening to books is currently the best, Yeguo Reading, install the latest version of .yeguoyuedu. 】

"Your news is very useful to me... Very useful... You are my friend. In the future, if you touch this mark, you can summon me."

The yellow light flickered away, leaving a round yellow mark on the back of Gretel's left hand, which sank into the skin and disappeared for a moment.Gretel felt the imprint, and raised his eyebrows happily:
"As long as it's useful!—Hey, in this case, can you ask for less gems?"

"No...a gem is a gem...every gem is different...not only what it's made of, but each one is different..."

The earth elemental spoke vaguely, but Gretel already understood.The reason why a gemstone is a gemstone lies not only in its elemental composition, but also in its crystal structure, the trace elements in it, and all aspects.

The reason why the earth elements want to own these gemstones is probably to study their crystal structure in order to make themselves harder and more radiant, right?

A thought flashed through his mind quickly.Open the box, grab a not-so-pure sapphire with many cracks, and hand it to the earth element:
"Then... can you do me a favor? Remove the impurities in this gem, pinch it tightly, and return it to me? As long as it is removed cleanly, I can give you ten gems!"

Not long after, a sapphire the size of a pigeon egg, crystal clear and uncracked, fell into Gretel's hands with a flash of light.

Gretel was overjoyed.

——This is net profit!A good relationship with the earth element is simply a gem printing machine!
