In the living room of the house, Pandora was still curled up in a wooden chair, looking a little chilly.

Richard's eyes flashed, and he found a blanket for Pandora to put over him.

As soon as the lid was closed, Pandora opened her eyes and looked.

"How?"

"Hot!"

“......”

Pandora threw the blanket away, twisted her body, and continued to curl up in the wooden chair, closing her eyes again.

Richard shook his head, turned around and walked into the study with a somewhat strange expression.

Walked behind the desk and sat down, his eyes fell back on the half-written papyrus scroll, and he picked up the quill pen and dipped it in ink, and Richard was ready to finish the last words.

"Rustling ......"

"After explaining the source of energy with star projection, there is a problem between mana and free energy elements. According to the method in the "Monroe Chapter", after the free energy element is ingested, it needs to be smelted and converted into mana, and then the spell can be released with mana.

So why do it?

Since the free energy element is a super-heavy element with a special effect, and when combined with each other, a special phenomenon (spell effect) will occur, so why should it be converted into mana?

A plausible explanation is that for the sake of safety.

It is precisely because the free energy elements combine with each other and can have special reactions, so in order to prevent the free energy elements from being stored in the Dharma source and reacting in advance, they must be converted into a stable ingredient - mana. Otherwise, before a wizard releases a spell, many free energy elements in the magic source may explode, freeze or acid at any time, and the magic source will be like an unstable bomb.

Mana should also be a high-order element, and it should be the most stable and decay element in the 'Stability Island'. Transforming the free energy element into a single stable element of mana through smelting can prevent the free energy element from reacting in the law source, and can ensure that the mana will not disappear out of thin air due to decay for a long time.

This way is obviously the safest.

Moreover, it is also standardized.

When releasing spells, you only need to find a way to mobilize the operation of a single element of mana in the body, so that it can run into a special state and transform into other energy elements to react, so as to present a specific spell effect and explosive power.

Because of this, a spell can be recorded and learned in a repetitive way, which constitutes the most fundamental mechanism of the wizard's spell system. ”

"Rustle...... Richard paused the quill in his hand, narrowed his eyes, and continued to write.

Of course, all of this is now just a hypothetical inference, like a castle in the sky and a castle on the beach, lacking a strong evidence to support it. One of the most crucial, fundamental parts must be proved in order for the whole hypothetical inference to become a reality. That is, it proves that the free energy element, mana, is indeed a high-sequence super-heavy element that has not been found on the earth, and it is real, not a fantasy. So now the thing to be solved is - how to prove. ”

How to prove it?

Richard paused his quill and began to think.

Proven, detected, and judged elements are considered analytical chemistry. In this regard, there is a complete set of sciences in the modern earth, with many subdivisions, such as spectroscopy, mass spectrometry, spectrophotometry, chromatography and electrophoresis

, crystallography, microscopy, electrochemical analysis, etc.

If it is specifically used to study elements, spectroscopy is more suitable, and it is better to study the light, sound or particles emitted, absorbed or scattered by the elements, and one of the most common methods is called the flame color experiment.

The flame color experiment is quite simple to do, all you need is a platinum wire, an alcohol lamp, and some dilute hydrochloric acid.

Of course, considering some special circumstances, it is better to use cobalt blue glass. However, cobalt blue glass should not be easy to obtain, and you need to obtain the raw materials to make it yourself, which may take a little time.

Richard walked out of the study and saw Pandora in the living room outside. I don't know how to pick up the blanket I lost before, half of it was under my body, half of it covered my body, and my two legs stretched out of the chair, dangling in mid-air......

Shaking his head, Richard walked into the room next to him, ready to refine the process of making cobalt blue glass.

......

In the blink of an eye, the morning came.

Richard stood in the courtyard, took a deep breath of the cold winter air, felt the coolness fill his lungs, spread throughout his body, and shook his whole body. At this time, there was already a complete plan for the production of cobalt blue glass.

Cobalt blue glass is a special kind of glass after all, which is made by adding cobalt blue to the glass.

In the current medieval world, the production of glass has been relatively perfect, although there is no bulletproof glass and tempered glass on the modern earth, but some common glass can be made, and some exquisite shaping and carving can be carried out.

Don't worry about the problem of glass, you only need to solve the cobalt blue.

Cobalt blue is a special blue pigment, which is often used in painters' paintings, and has the advantages of temperature resistance, light resistance, weather resistance, acid and alkali resistance, and bright color. However, because of the high cost of cobaltification in it, and because of the limitations of the technical level, it was not used on the modern earth until the nineteenth century.

If you want to get cobalt blue, for now, you need to make it yourself, and you need to use raw materials such as metal cobalt, alumina, and phosphoric acid.

As for how to get these raw materials, how to synthesize cobalt blue, and how to make real cobalt blue glass, Richard already has a perfect plan. After all, cobalt blue glass is really not a high-tech product, and the production process is not difficult, but it can only be said that it is a bit cumbersome.

Should I find a temporary assistant and let the other party help you get started and save some time?

Richard couldn't help but think.

Turning his head to look at the living room, he subconsciously glanced at Pandora, who was still shrunk in the chair, and found that the other party had wrapped the entire blanket around his body and shrunk into a ball.

Let Pandora be a temporary assistant and take a hit?

Well, forget it, as long as the other party doesn't cause trouble, it's enough, in a short time, don't have this plan.

So who to look for?

Richard was thinking about it when suddenly, at this time, there was a sound of horses' hooves outside the courtyard gate, and then there was a knock on the door.

"Bang bang bang. ”

Well?

Richard looked at the courtyard door and asked, "Who?"

"Your Excellency Richard, it's me!" Outside the door, Gro's voice came, with some irrepressible excitement in his tone, and he didn't know what was good.

Richard raised an eyebrow and walked out of the courtyard door to open it, letting Groh in, and his group of guards stood guard outside the door.

"You came over so early and asked me for something?" Richard asked casually as he walked into the courtyard with Groh.

"Well, that's the case......" Gro subconsciously rubbed his hands and said with a little embarrassment, "After meeting and separating from Your Excellency Richard that day, in fact, I didn't give up trying to become a wizard, but continued to meditate, wanting to prove myself." ”

"So?"

"So, just last night, I suddenly realized that I was still very talented!" Gro's voice couldn't help but rise, and his eyes lit up.

Richard's eyes flashed, and he didn't say anything, but he couldn't help but say in his heart: Are you sure you have talent? The night just passed, if it wasn't for his help, the consciousness body wouldn't be able to leave the body at all, right?

Wait, is it because ......

The next moment, Richard heard Gro say with excitement: "Do you know, Your Excellency Richard, the success rate of my meditation is not very high, I usually try many times to succeed once, and each success can only absorb a small number of energy particles.

But yesterday was different, as if I suddenly realized something, and after several failed attempts to meditate out of my body, I suddenly felt a different force acting on my consciousness body, allowing me to easily leave my body.

After leaving my body, my conscious body seemed to be able to move farther away from my body, absorb more energy particles, and be able to withstand it many times in normal times in just one time. Let's put it this way, the exercise I got yesterday was almost as good as all the meditations I had done before.

Do you say, did I suddenly break through some limitations? Does it mean that I actually have super strong wizarding talents, and I have super high potential, but I haven't tapped it before? And now after being successfully excavated, I can continue to meditate by leaps and bounds, and I can easily become a real wizard?"

"So, you're coming to see me so early?" asked Richard as he looked at Gro, his expression calm but his gaze slightly strange.

"Yes, that's why. Gro said loudly, "For the guess just now, actually...... I'm not entirely sure, just some speculation. Considering that I only know you as a wizard apprentice in the entire Emerald Kingdom, and you have more experience than me, I have to come to ask you, I hope it doesn't bother you. Anyway, what do you think, Your Excellency Richard...... What the hell am I in?"

"Uh, what's this......" Richard couldn't help but hesitate as he looked at Gro's hopeful expression.

In other words, should you tell the other party the truth?
