One of the reasons why the worlds created by the great power are called acquired worlds is the number and circulation of aura.

In the innate world, the amount of aura determines the level of this world, and it can circulate autonomously.

That is, after absorbing the spiritual energy, all the spiritual plants in those worlds will be fed back from the rhizomes buried in the soil to give back a part of the spiritual power, which will be converted into spiritual energy, replenished to this world, and make it circulate.

Moreover, in the innate world, there seems to be some kind of balance that is forcibly restricted, and no matter how strong the power is, it cannot break that limitation.

The strong can destroy a world, but they can't upset the balance within it, and this has been something that the strong who have a certain strength have wanted to figure out for endless years.

It's a pity that until now, no one has figured this matter out.

At the beginning, Shennong was bent on hitting the Ten Stars, and part of the reason was to solve this puzzle that had plagued him for countless years.

As for the acquired world, it's a completely different story.

They themselves are created by a variety of different creatures that have become powerful, and their efficacy and function are also for the great powers to provide them with something they need.

But everything that happens in these created worlds is to be adjusted and controlled by the one who created them.

For example, the aura of the grass world.

At the beginning, Shennong created this place to cultivate and plant spiritual plants, at least in terms of spiritual energy, he would definitely give sufficient supplies.

But with the fall of Shennong, everything in the Baicao Realm has become ownerless, and no one controls it, so it has become what it is now.

In fact, when Shennong created the Hundred Grass Realm, the division of labor and the definition of the three clans were very accurate.

As the leader of cultivating spiritual plants, the spirit clan naturally has to have the ability to control the spiritual energy.

And the spirit beasts and the human race are just supporting characters, so they don't have such abilities.

With the rise of the human race, the spirit race and the spirit beasts were all forced to shrink into their last protective circle, and the entire Baicao Realm was almost completely controlled by the human race.

They need spirit plants to improve their strength, but they don't have the ability to cultivate spirit plants.

Although there are spirit plants in the current Hundred Grass Realm, and they can fully meet the needs of the human race, if they want to plant high-level spirit plants or cultivate new varieties, the human race can't do it at all.

Since that war, they have been hunting down Spirit Clansmen everywhere, with the aim of driving them to help them cultivate and grow high-level spirit plants.

Cultivation and cultivation are two completely different concepts that cannot be confused strictly speaking.

Over the years, the Terrans have basically mastered the technology of cultivating spirit plants, but cultivating new varieties and planting high-level spirit plants are still only capable of being cultivated by the spirit race.

Moreover, the human race does not promote the way to maintain the balance of the spiritual energy when planting spiritual plants, so it has caused the spiritual energy in the Hundred Grass Realm to become increasingly scarce, and now it has reached the point of being about to dry up.

Liu Wei frowned and thought for a long time, but he couldn't figure out the reason, waved his hand and said:

"I don't understand it either, and now is not the time to think about this, let's find a place to settle down first, and the rest will be talked about later."

Hearing him say this, the Nether Girl couldn't say anything more.

Besides, this is not something she can solve at all, and it is in vain to think about it.

Before she met Liu Wei, what she thought about the most was how to survive.

But now, she rarely thinks about the problem.

It may not be a good sign, but she doesn't care.

As a creature with a cold physique, it is not easy to get to where it is today, and it stands to reason that the Nether Girl should really think about how to go further and make herself stronger.

But I don't know why, but now she doesn't seem to have any pursuit of power, but just repeats the mechanical life every day, and doesn't want to think about anything at all.

Perhaps, she is used to having Liu Wei arrange everything, and she just needs to do it according to his arrangement.

According to the direction pointed by the Yaksha at that time, Liu Wei and the Nethermaiden finally arrived at the city closest to Baicao Mountain after half a month.

It is said to be a castle, but in fact it does not even have a decent city wall, but it is a "castle" surrounded by an earthen wall more than one meter high.

In fact, this is a very normal phenomenon for the grass world.

When Shennong created the Hundred Grass Realm, not to mention the city wall, there was not even this kind of settlement, all the spirit races and human races were scattered and mixed together, and their daily task was to work, and their living conditions were the same as those of primitive people.

But now, these human races, who have undergone continuous evolution, have already had their own minds, not only to build cities, but also to build their own territory.

But at least so far, no one from everyone, including the three major families, has dared to put this idea into practice.

To build one's own territory means to shoot and expand the territory, which is equivalent to establishing a country and a regime.

And although these people have this desire and ambition, their courage has not yet grown to this point.

Therefore, there is no need for walls in these existing cities, because there is no need for war.

In all the cities of the Hundred Herb Realm, there are the forces of the three major families, although the medicine family is powerful, but if the other two are forced to be anxious and join forces to deal with the medicine family, the medicine family does not have the strength to deal with it.

So at least for now, the entire Hundred Grass Realm is relatively calm and stable on the surface.

After Liu Wei and the Nether Maiden entered the city, they found an inn to live in, planning to learn more about the Hundred Grass Realm before making the next plan.

As for the money, it is natural to use those few small things.

Liu Wei and the Netherwoman didn't have anything on them that could be exchanged for money, and if they rashly found a place to sell a few spirit plants, they were afraid that they would get into some trouble.

After thinking about it, Liu Wei still decided to treat it in special circumstances and use some dishonorable means.

Like, stealing.

But he and the Nether Girl definitely can't do it themselves, even if one of them has the advantage of space and the other has the advantage of speed, but that is not for them to steal.

Xiaomi and Benben have now also become eight or nine-year-old children, and Liu Wei has some psychological obstacles for them to do this kind of thing.

In this way, only Xiao Jiu and Bailing Worm are available.

Compared with the two, it is naturally a lark that is more suitable.

The Hundred Grass Realm is worthy of being the Hundred Grass Realm, and even the currency is replaced by spiritual plants.

It was a two-star spiritual plant called Purple Gold Wood, which had tenacious vitality, simple planting methods, and didn't require much aura.

The only drawback is that this spiritual plant has a very long growth period, and it takes twenty years for a tree to mature.

There are three types of currency made of purple gold wood, namely leaves, roots, and trunks, all of which are calculated in decimal places and are relatively simple.
