Chapter 167 Synthetic Gems
"No magic stone?" Li He looked at the stall owner with some doubts.

Magic stones are the common currency in the entire wizarding world. Using magic stones can make transactions much more convenient.And if you refuse to use magic stones and exchange things for things, it will be a lot of trouble.I don't know why the other party would do this.

"No magic stone, what do you want?" Li He asked.

"This thing." The other party said, groping in the robe for a long time, took out a blood-red gem the size of a finger, and gently placed it on the booth.

"Gem?" Li He raised his eyebrows under his robe and hat.

"It's a ruby." The young stall owner corrected, "Of course other gems are also acceptable, but the price is lower than that of rubies."

"If you use magic stones, you can also buy this ruby, why do you have to trade this ruby?"

"Do you think I want to be so troublesome?" The stall owner asked back, "I'll tell you the truth, there is a serious shortage of rubies in the entire Dark Heart Academy's sphere of influence, and it is really not necessarily possible to buy rubies with magic stones. So, I want to To buy books, you can only buy them with rubies.

For each book, two rubies of this size will do.For other colors, you need three.If you buy more, the price can be negotiated.But it must be traded with gems. "

The last sentence, the stall owner said very firmly, without any room for negotiation.

"Ruby..." Li He really didn't expect this booth to be so weird.

Of course he has rubies, but definitely not as many magic stones.

Using magic stones, he can easily buy all the books on the booth, and study carefully to see if he can break through the current bottleneck of meditation.

If you use ruby, according to the current quantity, you may only be able to buy a few copies, and it will be difficult to break through the bottleneck of meditation.

But he didn't give up. He scanned all the books on the booth, there were about 20 books, and asked, "If I bought all your books, how many gems would I need?"

"All... bought all of them?" The stall owner was surprised, and made an obvious movement of looking up.

After a long silence, I made a guess: "These are meditation-related books, which are rarely used by ordinary people. Let me guess, you must have encountered some difficulties in meditation... In addition to the 23 books I took out, I also There are eleven volumes, for a total of 34 volumes.

According to the price of two rubies in a book, you will be charged 68 rubies.I'll give you a discount, I'll charge you a hundred coins, how about it? "

"Ok?"

"Ha, don't be in a hurry, listen to my explanation. If you want all the rubies, it means that the difficulty you encounter in meditation is not ordinary, so it's just something here, it's hard to guarantee that it can be solved.

I will charge you one hundred rubies, fifty of which are for the price of the book, and the other fifty... I can take you to the private library of an official wizard, and let you check the relevant materials in the library, to solve your problem.

Fifty rubies, I will take you there five times, and each time I guarantee at least two hours, but the specific time is up to me, because I have to make sure not to disturb the wizard, otherwise we will have no good results.How about, think about it? "

Li He really didn't expect that the other party had such a proposal.

But speaking of it, the other party's proposal is indeed somewhat tempting.

A wizard's private library?Although the number of books is not as high as that of the library of Darkheart Academy, the average quality is definitely much higher.

After thinking for a moment, Li He nodded: "Yes."

"Okay, give me the gem. Tonight is a more suitable time. The wizard has no experiments and research. If you pay for the gem, I can take you there immediately."

"But I don't have so many rubies right now."

"..." The stall owner suddenly fell silent for a few seconds, his voice came out through his teeth, "Why... are you kidding me?"

"Don't get me wrong. I really don't have so many rubies right now...but if I can wait, I will have enough rubies to trade with you tomorrow."

"you sure?"

"very sure."

"Well, it's a deal. I'll be here waiting for you at this time tomorrow night."

"Okay, see you tomorrow night."

"Don't break the appointment! Don't be late!"

"it is good."

Li He turned around and left, leaving the black market straight away.

Now that it is possible to break through the bottleneck of meditation, the only problem is how to get enough rubies.

According to the stall owner, rubies are scarce in the entire Darkheart Academy.

So if you want to get rubies, you can only leave the scope of the Dark Heart Academy and go further afield to purchase.

Or... using scientific methods to directly synthesize it artificially.

Yes, rubies can be artificially synthesized.

……

Li He quickly returned to the dormitory and entered the Black Stone Castle.

As soon as he entered, the devil Alencus greeted him and quickly greeted him: "Great master, you are back."

As he spoke, he opened the notebook and said: "According to your arrangement, the 47th variation cultivation experiment of enchanted plants will start in half an hour, the analysis experiment of enchanted items will start in two hours, and the experiment will be carried out in three hours. Fusion blood agent optimization test... Look, do you want to prepare?"

Li He waved his hand: "Postpone all the arrangements for tonight, I have new arrangements."

Alenkes was taken aback for a moment, then quickly realized, and quickly asked: "The great master Li He, is there anything you need me to do?"

"Go to the warehouse in the logistics area and fetch #0983, #1048, #1456...the materials, the quantities are..." Li He said.

Alenkes quickly recorded in the notebook, nodded for a moment and hurried towards the warehouse.

……

moment.

Blackstone Castle, in the processing workshop of the logistics area.

A huge metal table was filled with a large number of instruments and materials brought by Alenx.

Li Hyuk looked at an iron box, and saw that there was a light red cuboid solid inside, somewhat similar to bricks.

But it is obviously softer, without the hardness of bricks, more like brick powder sticking together.

This is bauxite ore that has undergone primary treatment. It should be grayish white, but because it contains iron impurities, it appears light red.

Li He took out the bauxite ore from the iron box, and started further processing according to a series of procedures.

First crush the bauxite ore, and then add a large amount of hydrochloric acid to the container to remove SiO2 impurities.

Afterwards, sodium hydroxide solution was added, and the ferric hydroxide precipitate was removed by filtration.

During the process, Li Hyuk would occasionally refer to a flow chart on the desktop.

Devil Alenx glanced curiously, only to see various chemical equations written all over it:

Al2O3+6HCl→2AlCl3+3H2O，Fe2O3+6HCl→2FeCl3+3H2O……4NaOH+AlCl3→NaAlO2+3NaCl+2H2O，3NaOH+FeCl3→Fe(OH)3↓+3NaCl……2NaAlO2+CO2+3H2O→2Al(OH)3↓+Na2CO3……

The dense characters and marks are like many black worms wriggling on the paper, as if they will break out of the paper in the next moment.

Alenkes couldn't help but let out a muffled snort, quickly looked back and found that the whole brain was numb, and his thinking was a little stagnant for a while.It was like a yellow dog passing by, who was hit with a club for no reason.

He breathed heavily with some palpitations, tried to calm down his mental discomfort, restrained his curiosity, and dared not look at any materials that Li Hyuk referenced.

But Li Hyuk didn't pay attention to these, and was still busy, pouring various liquids into the mixed solution and performing various treatments...
