let go of that priestess

There was no one to accompany Hong Lian at night, and she also fell asleep, but according to her habit, even if she deliberately controlled it, she would probably have to sleep for a long time.

The dining table was cleaned up and moved outside. Ji Cheng sat at the table and called Jiang Hongdou to come over and discuss with her.

No, popularize the idea before discussing it, and start with the simple one.

"For example, now is the time when you migrated before, and there was no unified deployment of materials and so on.

Then we are good friends in the clan.

Now I am in urgent need of animal skins to make clothes and meat is rich. You are in urgent need of meat and are willing to wear cooler clothes. Then I will exchange meat with you for animal skins. Do you want to exchange them? "

"Uh, why does it always feel a little strange."

"Don't worry, it's just an example."

"Okay." Jiang Hongdou tilted his head and said: "Exchange, isn't this just an exchange of items, and the clan used to have them."

"Yeah." Ji Cheng nodded: "Then I'll exchange some shells with you for animal skins, do you want to exchange them?"

"?...No change."

"What if these shells could be exchanged for meat at a third person?"

"Huh?" Jiang Hongdou's face became strange:

"Exchange, I will exchange shells with you, and then exchange shells for meat. It is actually the same. What do you want to say?"

"The currency system I want to build is similar to the shells here, which can be exchanged for almost any material that can be exchanged, and this form is called purchase."

"This......"

Change to almost everything! ?

Jiang Hongdou stared slightly, and understood, but there was a problem: "Shells can be picked up everywhere by the river."

"Yes, so this currency needs to have a special, official logo, which cannot be reproduced by outsiders.

Then set the rule that only with this logo can you exchange almost some materials and buy them.

In addition, it is best not to have too much value in the currency itself, such as made of shells mentioned earlier.

But it must also be considered that it will be frequently tossed and circulated, so portability and durability must also be considered, and shells are not suitable for durability. "

Ji Cheng does not want to follow the old path of currency development, using various useful metals to make currency and the like.

Even if he wanted to use various metals, Oki Village couldn't afford to make this kind of currency.

Not enough raw materials, not enough technology, not enough manpower.

In fact, the most ideal situation is that currency only exists in data, not in kind.

But for Damimura, which doesn't even have electricity, don't mention digital currency or virtual currency.

After Jiang Hongdou understood what Ji Cheng needed, she helped her think.

After thinking about it, you can use it everywhere, including stones, wood, and leaves.

Stones and leaves, again outweighed by the demands of portability and durability.

For the rest of the wood, the two were having a headache how to make a logo that outsiders could not imitate.

Jiang Hongdou rubbed her brows and said, "There must be some special mark, if not, it's not much different from the shells picked up by the river.

If it is very easy to imitate, your way of... buying will cause big problems! "

"Well, you understand quite right."

Ji Cheng thought about it differently: "Either develop some new technology and keep it secret, such as lacquer, and paint different colors of lacquer on wood."

He thought of the kind used in casinos a long time ago.

But then he denied it: "No...you can't keep lacquer a secret, it will be used in large quantities after all."

"Want a technology that won't be used a lot?"

Jiang Hongdou shrugged helplessly: "The knowledge of new technologies is all in your mind, how can I help you think about it.

But... Speaking of technology, there is indeed a technology that will definitely not be used in large quantities, if it is called a technology. "

"what?"

"Magic element."

Jiang Hongdou pointed to the silk thread on Ji Cheng's wrist: "Magic."

"Eh!?"

.

Chapter 104 Magic Creation

Hong Lian was lying on the bed sprawled, her mouth was open and closed, half of her belly was exposed, one leg was bent, and her foot stepped on the other straight leg.

Overall, it looks silly...

When she was sleeping, her consumption further decreased, and even the magic essence gradually increased with the transformation.

Therefore, Honglian, who was able to sleep peacefully, became more reckless, and did not control her sleeping position.

However, the time to sleep should be controlled, and it is more interesting to be awake.

Hmm, I feel like I've almost slept, probably the sleep time of human beings.

Guren thought, slowly controlling herself to wake up.

"red lotus?"

"Wow!......"

As soon as Honglian opened her eyes, she saw two people sitting in front of the bed, she was caught off guard and was shocked.

"Zhi, dear friend, why are you here?"

"Hey, sorry to scare you, we don't know when you wake up, so we'll just wait here."

"I'll communicate magic with you when I wake up..."

"Uh, don't talk about that."

Ji Cheng rubbed his hands, his eyes brightened and he said, "Teacher Honglian, shall we start learning magic element and magic right now?"

"Eh? Oh, okay."

Honglian was a little confused: "No problem, but are you in such a hurry?"

"He's in a hurry now." Jiang Hongdou shrugged, "Honglian, are you up?"

"Get up! You don't want to lie down when you wake up, wheelchair?"

"Here it is."

Jiang Hongdou gestured to go behind her, then picked up Hong Lian, who was half a head shorter than her, and put her on the wheelchair.

Ji Cheng pushed the wheelchair out, and the two came to the table and sat down together.

Xiao Bai was lying on the ground, yawning comfortably.

Seeing the master, the mistress, and the boss covering him come out, it quickly got up, ran over and rubbed each other, and then lay down comfortably.

"Ow~"

This wolf life is really comfortable.

Well, it should be very comfortable, but recently, I always feel a little uncomfortable somewhere.

Xiaobai tilted the wolf's head. For some reason, he seemed to think of the little she-wolf who ran together. How is she doing recently?

......

Ji Cheng wants to learn magic, but his request is very strange.

At this moment, Honglian was stunned after hearing his description, and reluctantly concluded:

"Uh, buddy, you want two magical... connections.

Swipe one of them against the other, or swipe it, or paste it, etc., can it reduce and increase the number displayed by the magic element in the former? "

Jiang Hongdou was also dumbfounded when she heard that, it was obviously not what she discussed with Ji Cheng before.

"Aren't you going to use magic as currency? What is this?"

"e is also currency, a more advanced use."

Ji Cheng raised his wrist, touched the silk thread and said:

"You reminded me that if there is magic, it may not be limited to what we discussed before."

He turned to Guren and said, "How is it? Is there such magic?"

"No......"

Honglian smacked her lips in embarrassment and said, "I didn't even understand the meaning of this magic.

Therefore, meaningless magic will not be passed on, let alone known to me. "

"Ok."

Ji Cheng shrugged, he didn't expect too much from this.

After all, the Naga, orcs, dwarves, elves and other city-states that Honglian said sounded like that.

His expectations were on the other side: "Can this magic be created?"

"Best friend wow..."

Honglian couldn't laugh or cry when she heard the words: "Create magic? How dare you say it!

Every outline and structure of the magic circle has different meanings, and the combinations between them are endless.

And to find out what is useful to us and combine it correctly requires endless years of trying.

This is true regardless of whether it is the most common general-purpose magic or the racial magic that is only spread among various tribes.

If you just increase the power of some low-level magic, it can be done.

But that is because there is a relatively higher understanding of the same kind of magic, and the low-level magic is only improved, and it is not considered a creation.

In short, those magic principles are summed up by the ancestors, and creating magic is not easy.

It's not impossible for you to create this kind of strange magic now, but you have to study it from scratch..."

"Well, if I have some, what's the point?"

Ji Cheng didn't give up: "Magic, in fact, is the different uses of magic essence, right?"

"So it is."

Honglian felt that he still didn't understand the difficulty of creating magic, and sighed softly: "What reason do you have?"

"For example, I know about full adders and full subtractors, and I know about logic gates."

Ji Cheng knew that the two girls must not have understood, and continued to explain: "Let's talk about the door first, we have to start with the truth table.

I will name an operation 'not', and its definition is - 'the opposite of any proposition. '

So now there is a proposition p is true, so not-p is false, so we can get a truth table of p and not-p.

p is true, not p is false.

p is false, not p is true.

接着我用1代替真，0代替假，就可以输入0输出1，或者输入1输出0

This is a NOT gate.

Then let’s talk about the AND gate, uh…”

As Ji Cheng was talking, he found that the expressions of the two women became more and more confused with the explanation, so he shut up immediately.

He's already started with the most basic...isn't it okay?

After the NOT gate, AND gate, NAND gate, and XOR gate are all known, a full adder can be combined.

Then one full adder can represent 4 different numbers, two full adders represent 8, and three full adders represent 16.
