Still, Rean decided that learning the Circuitry Formations would come first.

"By the way, Sister Orb. Can I make copies of the Circuitry Formation Articles and bring them outside? It would be good to have Droman's help with it."

​​

[You can, but I wouldn't recommend that. You should think about your Destiny Points. Suppose they learn the Circuitry Formation by themselves. In that case, you will only get an indirect amount of Destiny Points for the changes it brings later. After all, the Circuitry Formations made by them were thought up by them. They wouldn't be something that you introduced to the world like the Communication System.]

[The best thing to do is to learn them first, then come up with a few ideas to use before teaching Droman and the others yourself. In that case, the system will consider that you were the main reason for everything.]

"I see... Alright then."

Without wasting time, Rean dove into the articles of the Electrical Formations Repository. However, soon after, Rean found out that each of the options available had many more sub-options inside. Just the Spiritual Electric Current Usage and Control article alone had thousands of pages! Let alone learning it, just to finish reading the articles would take several weeks!

"This is a lot more complicated than I expected."

[Of course! Did you forget how many rune arrangements can be made with the usual formations? If they already have so many things to study, how about Circuitry Formations, which is more compact and complicated.]

"Ahem... Isn't there a form of pouring all the knowledge directly inside my brain?"

[I wouldn't recommend that.]

"Why?"

[Simple. Memorizing and learning are two completely different things. Chances are that the excess information will make you pull the cart in front of the horses. Suppose you get all the information at once and start to learn it. Because you already have the rest of the advanced data, you will try to apply it even though you shouldn't. The best thing is to do it step by step.]

Rean understood what Sister Orb meant.

"Sigh... I wonder just how long it will take before I finish everything."

[Go! Harvard's best student of all time! You can do it!]

Rean's mouth twitched.

"Fuck you!"

[Hahaha!]

Back outside, Roan arrived at Old Worm's hut. Surprisingly, Old Worm was already there, waiting for him.

"Weren't you supposed to be in the Alchemist Hall Repository?"

Old Worm shook his head as he replied.

"It has been a long time since our last session. I wanted to see how much you improved on your own during this time."

Roan nodded. During wartime, he also concocted pills for the other cultivators in his group several times. Those guys used their own merit points to buy the items, so it was a great chance to train alchemy with free materials. Although Roan couldn't step into the Earth Peak-Level Alchemist Rank, his own concoction proficiency improved quite a bit.

Roan then pondered a bit if he should use the Soul Gem System Cauldron in front of Old Worm or not. However, he didn't think about it for long. He and Old Worm had spent a lot of time together, so he knew what kind of person Old Worm is. Roan was sure that Old Worm would never try to steal it or reveal the information if he asked.

"I got something interesting for you to see."

Roan had already brought the cauldron out when he left his room, so there was no need to pretend to go back to take it. Roan then brought the thing inside for Old Worm to take a look.

At first, it looked like any cauldron. However, Old Worm quickly found something different to it.

"What are those metal spikes? Also, isn't its base way too big?"

The cauldron's base was at least twice as thick when compared to a normal cauldron. It would usually make it much harder to control the fire since it would take longer to transfer the heat. The spikes were even more of a puzzle since they could also affect the usage of the cauldron.

Roan faintly smiled as he also showed something else to Old Worm. It looked like a small sphere attached to a box. Only half of the sphere appeared outside. In fact, there was only one half of a sphere. Inside the box, many components made up the heat control system of the cauldron, but that wasn't all. The box had the same number of 'spikes' as the cauldron.

Roan already received the method on how to use it from the Soul Gem System, so he quickly prepared everything. Well, all he needed to do was to put the cauldron under the fireplace and turn it on. But it was then that something happened. All the 'spikes' on the cauldron began to emit some kind of Spiritual Current that reached the 'spikes' of the small gadget.

As for the base, many runes began to shine nonstop as the fire touched it.

"This... What kind of Spiritual Cauldron is that?"

Roan then pointed at the sphere on the box.

"Send your Spiritual Energy and Sense into the Sphere. You will understand once you do that."

Old Worm wasn't an idiot. He could tell that there was some Formation inscribed on the Cauldron. It wasn't hard to guess that it had something to do with the fire either. However, as soon as he did what Roan said, a stream of information appeared in his mind. Several lines were depicting various numbers that changed constantly.

"This... temperature? It can show the temperature in the form of numbers, is it?"

Roan nodded.

"Yes."

Old Worm was really surprised by that.

"This is some excellent stuff. It's a lot easier to control the temperature with something like this."

Roan then touched the sphere as well before sending a Spiritual Sense command inside. In an instant, the continuously changing temperature numbers froze in place. Simultaneously, the runes under the base of the Cauldron shone as the fire hit it.

"What?! That's possible?!"

Roan nodded.

"This cauldron can control temperature perfectly. As long as there is enough heat, you can select any number to stop."

Old Worm couldn't help but ask straight away.

"Where can I buy one?"

A burst of rare laughter came out of Roan's mouth. It wasn't easy to make someone like Old Worm act like this.
