Traveling through time as a goblin, just wanting to live a leisurely life

The lavender paper money glowed with light. The front was printed with the simple words "1" and "Spirit Coin", while the back was filled with instructions for use.

According to the above description, all the fonts on the banknotes are printed with the method of gold stamping using the space gems ground into powder, which has a built-in space effect. As long as you stack several spirit coins together, they will automatically be stored in one spirit coin.

When other spirit coins are stored, the number on the front will change. For example, if there is a "1" spirit coin, it will become a "5" spirit coin after storing 5 spirit coins. A maximum of 1 million spirit coins can be stored. And spirit coins can be stored in other space magic weapons, which is very convenient to carry.

“Nice design.”

You Youzi stroked his beard and smiled. He didn't expect that these three people could come up with such a convenient function.

Afterwards, You Youzi input a trace of mental power according to the instructions, and the fluorescence on the spirit coin suddenly lit up, and a green flame ignited instantly and burned the spirit coin!

You Youzi threw out the burning spirit coin, and the instant it landed on the ground it turned into a short black You Youzi, which turned out to be You Youzi's inner demon!

The little demon didn't move at all, standing in front of Youyouzi like a motionless statue, but as long as Youyouzi looked at it, he would naturally make a connection in his heart, and his emotions would immediately surge. If he could calm down and observe, he could observe the various components of the demon and find the shadow hidden deep in his heart.

About 10 minutes later, the inner demon disappeared. You Youzi let out a long sigh, smiled and nodded continuously, saying "OK... OK... OK..."

You Youzi's series of movements woke up the three sleeping people, and everyone greeted You Youzi with sleepy eyes.

"Morning, Taoist Priest..."

"Good morning, ancestor!"

"Don't call me ancestor!"

"Understood, Patriarch."

You Youzi: ...

"You have used up a spirit coin, right? How do you feel?"

As the leader of the currency plan, Mo Ling immediately woke up from his sleep and looked at You Youzi with confidence in his eyes.

"Not bad, very good, very good. I thought you would add some effects related to the power of emotions, but I didn't expect you to just come up with a 10-minute inner demon illusion."

The currency of the fairy world cannot be just a piece of metal or a piece of paper. This is the consensus of all the fairies. You Youzi originally thought that they would use the materials of the heart sea to make a currency that can arouse the power of emotions, so that practitioners can cultivate their mind by holding it, but he did not expect that these three juniors would do better.

There are hidden dangers in adding emotional power to the currency, because there is nothing in the fairy world that affects the state of mind, and Yigan's heart sea specialty is unique. If they really add emotional power to the currency, the currency will become the only treasure in the fairy world that can train the state of mind. Who would be willing to use this treasure as a trading tool?

Now, this inner demon phantom that can only last for 10 minutes solves this problem very well.

The inner demon phantom is completely created according to the psychological shadows in the user's mind, which can help the user clearly see his or her own mental problems. However, the appearance of the inner demon will also strengthen the user's emotional and desire fluctuations, increase the user's mental burden, and even if it is an illusion, it is not suitable for long-term use.

The best way to use this spirit coin is to use it every once in a while to check your mental state, just like a physical examination. It can't even affect the enemy's mood immediately like the heart dust, so its value is greatly reduced.

This characteristic of being somewhat useful but not very useful makes it very suitable for use as currency. Immortals need it for cultivation, so they naturally keep some on them. However, its usefulness is actually not as great as imagined. When immortals need something urgently, they are very willing to take it out for exchange.

As people used spirit coins to exchange for other items more and more often, spirit coins naturally became the standard for measuring the value of things, and became the currency unit of the fairy world.

Moreover, the space effect of the spirit coin also makes it very convenient for everyone to trade. It can measure some small transactions, and can also be stacked into tens of millions of units for large transactions. It takes into account the two benefits of immortals' cultivation and circulation.

"I really didn't expect that you would use the magician's method of making scroll bars to create such a demon phantom, and I didn't expect that you would use the talisman technique to make a space magic weapon. I think this design is great, but I am only worried about one thing, is this spirit coin easy to counterfeit?"

Youyouzi asked.

"It is easy to analyze the ingredients, and the manufacturing technology is not difficult, but it is not so easy to obtain the production materials or substitute materials."

As Mo Ling spoke, he took out another spirit coin and explained to You Youzi:

"In order to be able to carry the power of the scroll and the talisman technique at the same time, the paper for the spirit coin is made of two bamboo leaves from the Iron-eating Beast Forest wrapped with a piece of Heart Demon Kelp. The bamboo leaves are used to write the talisman text, and the Heart Demon Kelp is used to make a scroll that summons the Heart Demon phantom. Both materials are difficult to obtain, and it is difficult to generate the same material with the mind, so it is difficult to imitate."

The Heart Demon Kelp is a seafood that appeared when Master Zhengguang's heart demon took shape in his heart sea. The emotional power contained in it is too strong and no matter how it is purified, it is not suitable for human consumption.

However, the inner demons like this food very much. Except for Yigan’s inner demon, all the inner demons in the Heart Sea eat this kelp as their staple food, so Yigan directly named it the Heart Demon Kelp.

Therefore, most immortals do not know that there is food such as Heart Demon Kelp in the Heart Sea, so it is naturally difficult to find this raw material. The bamboos in the Iron-eating Beast Forest are all in the residence of the Iron-eating Beast, so it is not easy to get bamboo leaves from it.

"In addition, the Heart Demon Seaweed is coated with a layer of special glue made from jellyfish, which isolates the bamboo leaves and the Heart Demon Seaweed. This ensures that the two spells will not affect each other and also adds a hidden anti-counterfeiting measure. Few people can notice this layer of glue."

"In addition, I will completely close the sales channels of space orbs. From now on, the immortal world will not be able to buy any space orbs. They will only be used for spirit coins."

Mo Ling and Yi Gan took turns explaining to You Youzi, and You Youzi nodded as he listened.

"Very good. Monopolizing materials is indeed a good idea, but it is not impossible to find a substitute for such a currency. If someone can develop a more useful currency, it can completely replace your currency."

You Youzi said.

"It doesn't matter. As long as Xin Hai's services are there, any currency will do. And in the next few years, it shouldn't be that easy to find another material that is useful to all practitioners. By then, we will have made a lot of money and can exit."

Mo Ling has a very good attitude and is not greedy at all.
