If this weapon wants to cause damage to the immortals, it must not be a mortal aircraft cannon, it requires a very high-grade energy weapon.

The alchemists in the karmic fire hell have a lot of experience, after all, it is a Shinto weapon, not an immortal weapon, Fu Yang wants to develop an immortal Dao refining force, and the two cooperate with each other, and then have greater results in a single weapon.

As soon as he ascended to the Heavenly Realm, he was basically a Void Immortal, and it took a certain amount of time to transition to a True Immortal, and in general, his combat power was very insufficient.

Tianluo Academy alone was able to sweep away the army that had ascended to the Heavenly Realm, and it was a one-sided slaughter.

In this way, the only way to close the distance is the weapon.

Fu Yang, Tai Bai Xing, Li Qingchuan, the three of them are planning together how to transform the underworld.

"Your Majesty, I think there is a problem to solve, the lifespan of ghosts is different, there are long and short, how to plan the existence time?" Tai Bai Xing said.

Yes, the yin life of ghosts is even ten times that of ordinary people, and there are many old ghosts that exist for thousands of years, or even thousands, and have been living in the world, although they have not made a big move, but there are hidden dangers, and it is possible to destroy the order of the underworld if they are not careful.

The longer the ghost lasts, the more it grows, no matter what way it grows, it grows to a certain extent, and there is a lot of power in the body, like a ghost nest that gathers together, and there are many disobedience.

"It's very simple, catch all the evil ghosts and throw them into hell, and the ghosts who have not committed anything will give warnings, and in the future, the underworld will prosper, and if you want to live in the underworld, the period will be a thousand years, and if there is anyone who disrupts the order, you will be directly beaten to death." Fu Yang said it simply and rudely.

"Is it necessary to establish a monetary system?" Li Qingchuan asked.

"Currency!" Fu Yang's eyes lit up.

At this point, he really didn't think that he would make things simple, but forget the most critical point, the circulation of currency.

Not bad. Any society has money as a basis, in reality, on the basis of gold and silver, derived paper money coins, all have an economic basis, if the underworld is the same circulation paper money. There are a lot of problems, and even real coins have to face all kinds of problems.

"I have an offer." Too platinum star road.

"Tell me about it." Fu Yang cheered up.

"Demons need evil energy, monks need aura, so let's make a currency that can store energy." Tai Bai Xing smiled.

"This is a good idea, whether it is a monk or a demon or a monster, all kinds of energy are needed to maintain cultivation, so this kind of currency itself has value, isn't it just like a spirit stone and fairy stone, it can be used for trading. It can also be used for cultivation, and it has value in itself, so naturally there will be no depreciation. Fu Yang's mind flashed with inspiration, and he continued: "We don't need to make currency, but let the expanding sentient beings help us make it." ”

"What does that mean?"

The two of them couldn't figure it out, how could the sentient beings come back to help them make money, so that they would not have absolute control over the currency.

"Regardless of the spirit stone and the fairy stone. There is a limit to the number of beings, but there is no limit to all beings. What we have to do is one thing, that is, to create paper talismans that carry energy, and all kinds of cultivators can infuse the corresponding spiritual qi by themselves, and the spiritual runes produced can be used by anyone, and then. The underworld has all kinds of facilities, not only ghosts can come, but all kinds of monks can come, as long as you have spiritual runes, as long as you obey the order. Welcome to the underworld, build a few tour groups, I estimate that we will make a lot of money, we control the most important link, establish a bank, and the bank on earth will be managed by the city god......"

At this moment, they were already dumbfounded by Fu Yang's imaginative thinking, and they were not afraid of playing the Three Realms badly.

"Then how do we divide the amount, like coins, there are one, five, ten, etc., and how do we measure and distinguish?" Tai Bai Xing asked.

It's a very important question, what should I do if the exchange value of a single value rune is slightly exceeded, is it difficult to take out another one, use up part of the energy and then pay, it is not an extra move.

Regardless of the spirit stone, the fairy stone has a grade, which makes it convenient to trade, of course, this is a natural quality problem, and external forces cannot be changed.

"I have an idea." Li Qingchuan said excitedly.

"Say, be bold." Fu Yang thought about it with enthusiasm, and he had already looked forward to a corner of the future.

"According to the year, month and day, the weakest ghost, there is always a limit to the evil qi condensed in a day, and this limit is exactly to maintain one day of cultivation, that is, the lowest face value of the spirit rune, that is, the day rune, and then the moon rune, which can maintain thirty days of cultivation, and the year rune can be maintained for exactly three hundred and sixty-five days." Li Qingchuan said what was in his heart.

"It's so clever and talented, and it's wonderful that cultivators have time, and at the same time, they care about time the most." Fu Yang agreed.

This method of division is indeed simple and clear, there is no time for cultivation, and there is a limit for longevity, which is also a reminder to monks to actively work hard, you must know that the level of a monk's cultivation is related to how much aura he accumulates in a day.

Even if a Qi Refining Cultivator is filled with a day talisman, that Yuan Infant Cultivator can fill a year talisman in a day, in short, the higher the cultivation, the richer the richer, it doesn't seem very reasonable, if you want to be rich, cultivate more.

Moreover, it is very simple to manufacture and store the spirit rune, the raw materials are separated from the yellow paper, a hundred pieces of more than a dozen bundles, and it is not a problem to cut out a few thousand, and then release the drawing pattern, and do it yourself.

"The currency above is the fairy jade." Fu Yang took out a piece of immortal jade.

It was just the lowest grade of first-grade immortal jade, which could be found everywhere in the heavenly realm, the most basic currency in circulation.

"What's the swap ratio?" Li Qingchuan asked.

"10,000 New Year talismans, in exchange for a piece of first-grade immortal jade." Fu Yang smiled.

"Isn't that too high for ordinary people to afford." Li Qingchuan said worriedly.

"Immortal jade contains immortal energy, ordinary monks can't use it, set it higher because it is easy for high-level monks to make year talismans, but to make a 10,000-year amount, it is not an easy and ordinary thing, of course, a piece of first-grade immortal jade wants to cultivate to immortals, the demand is very great." Tai Bai Xing explained.

"That's right, in general, we always control the economic lifeline, and the immortal qi is the key to becoming an immortal, and then the immortal qi has nine grades, each of which is exchanged for hundreds of pairs, unless the wealth is immeasurable, or the merit is exchanged, both of which are controlled by the heavenly court." Fu Yang smiled obscenely.

However, they knew that the only thing to be solved was the problem of the foundation, and with Fu Yang's permission, the alchemists and the army of gods in the karmic fire hell were mobilized to cooperate in the construction.

For a time, the entire underworld was mobilized, and various ghost towns entered the garrison to salvage scientists.

Form research groups one by one, distribute the information of the way of refining weapons, and the corresponding cultivation resources, and start a new aspect of research.

All kinds of ore resources are very easy to solve, and there are many galaxies, beyond the scope of the solar system, mining mineral deposits on planets at will, and finding them in the energy conduction metal plane.

The foundation of the underworld is solidified, waiting for the erupting monks to ascend to the heavens. (To be continued.) )
