Chapter 167 Synthetic Gems
"Don't want magic stones?" Li He looked at the stall owner, a little confused.
Magic stones are the common currency of 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, you will be in a lot of trouble. Don't know why the other party did 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 placed it gently on the stall.
"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 acceptable, but the price is lower than the ruby." "If you use magic stones, you
can also buy this ruby, why do you have to do this? Ruby trading?"
"Do you think it's so troublesome for me?" the stall owner asked, "Let me tell you the truth, there is a serious shortage of rubies in the entire Dark Heart Academy's sphere of influence. If you have magic stones, you may not be able to buy rubies. .So, if you want to buy a book, you can only buy it with rubies.
For each book, two rubies of this size are enough. If it is of other colors, you need three. If you buy more, the price can be negotiated. But it must be traded with gems."
The stall owner said the last sentence very firmly, leaving no room for negotiation.
"Ruby..." Li He really didn't expect this stall to be so weird.
He certainly has rubies, but definitely not as many as magic stones.
Using magic stones, he could easily buy all the books on the stall and study them carefully to see if he could break through the current meditation bottleneck.
If you use rubies, based on the current quantity, you may only be able to buy a few copies, and it will be difficult to break through the meditation bottleneck.
But he did not give up. He glanced at all the books on the stall, about twenty of them, and asked, "If I bought all of your books, how many gems would it cost?" "Buy them all...all of them?" The stall owner said
. He was surprised for a moment, and made an obvious move to look up and look over.
After a long silence, he guessed: "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 twenty-three books I have taken out, , there are eleven more books, a total of thirty-four.
According to the price of two rubies per book, I will charge you sixty-eight rubies. I will give you a discount and charge you a hundred rubies. How about it?" "
Yeah ?"
"Ha, don't be anxious yet, listen to my explanation. If you want all the rubies, it means that the meditation difficulty you encounter is not ordinary, so it is just the things here, it is difficult to guarantee that it can be solved. I charge you a
hundred rubies, fifty rubies are to pay for the book, and the other fifty... I can take you to the private library of an official wizard and let you check the relevant information in the library to solve your problem. .
Fifty rubies, I will take you five times, each time guaranteed to be at least two hours, but you have to listen to me for the specific time, because I have to make sure not to disturb the wizard, otherwise we will not have a good result. How about, think about it For a moment?"
Li He really didn't expect that the other party would make 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 Dark Heart Academy Library, the average quality is certainly much higher.
After thinking for a moment, Li He nodded: "Okay."
"Well, give me the gems. The time is more suitable tonight. The wizard has no experimental research. If you pay the gems, I can take you there immediately."
" But I don't have so many rubies now."
"..." The stall owner suddenly fell silent. After a few seconds of silence, his voice came out from between his teeth, "Why... are you teasing me?" "
Don't get me wrong. I'm really not like that now. Many rubies... But if we can wait, I can have enough rubies to trade with you tomorrow."
"Are you sure?"
"Very sure."
"Okay, it's a deal, I'll be here at this time tomorrow night , waiting for you here."
"Okay, see you tomorrow night."
"Don't break the appointment! Don't be late!"
"Okay."
Li He turned around and left the black market.
Now that it is possible to break through the meditation bottleneck, the only problem is how to obtain a sufficient number of rubies.
According to the stall owner, rubies are scarce throughout Dark Heart Academy.
So if you want to get rubies, you can only leave the scope of Dark Heart Academy and go to further places to purchase.
Or... use scientific methods to directly synthesize it artificially.
Yes, rubies can be synthesized artificially.
...
Li He quickly returned to the dormitory and entered the Blackstone Castle.
As soon as he entered, Devil Alex came up to him and greeted him quickly: "Great Master, you are back." As he spoke, he
opened the record book and said: "According to your arrangement, the process will start in half an hour. The 47th mutation cultivation experiment of demonized plants. The demonized item analysis experiment will begin in two hours, and the fusion blood agent optimization test will be conducted in three hours... Do you think we need to prepare?" Li He waved his hand
: "Postpone all the arrangements for tonight. I have new arrangements."
Alex was stunned for a moment, then quickly realized and asked quickly: "Then great Master Li He, what do you need me to do? What?"
"Go to the warehouse in the logistics area and get materials #0983, #1048, #1456...the quantities are..." Li He said.
Alex made a quick note in his notebook, nodded for a moment and hurried toward the warehouse.
...
for a 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 that Alex had brought.
Li He looked at an iron box and saw a light red rectangular solid inside, somewhat similar to bricks.
But it is obviously softer, without the hardness of bricks, more like brick powder stuck together.
This is bauxite ore that has undergone primary treatment. It should be gray-white, but because it contains iron impurities, it appears light red.
Li He took out the bauxite ore blocks from the iron box and started further processing according to a series of processes.
First, crush the bauxite ore blocks, and then add a large amount of hydrochloric acid to the container to remove SiO2 impurities.
Then add sodium hydroxide solution and filter to remove the iron hydroxide precipitate.
During the process, Li Hyuk would occasionally refer to a flow chart on the desktop.
Devil Alex glanced curiously, only to see various chemical equations written full of them:
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 densely packed characters and marks are like numerous black insects squirming on the paper, as if they will burst out of the paper in the next moment.
Alex couldn't help but groaned, and quickly looked back to find that his entire brain was numb, and his thinking was stagnant for a while. It was like a passing yellow dog that was hit with a stick inexplicably.
He took a big breath with some palpitations, trying to calm down his mental discomfort, restrained his curiosity, and did not dare to look at any of the materials Li He referred to.
But Li He didn't pay attention to this. He was still busy, pouring various liquids into the mixed solution and performing various treatments...
