With the brain that is enough to simulate the universe.

He modeled in [the mind space], and the model of the city he designed naturally took all aspects into account as much as possible.

Building a city from scratch on a vacant piece of land is much easier than rebuilding an existing city.

Therefore, to build a model, you don't even need to spend too much time on Eryi, just take the classic designs of major cities in the world and use them.

So, although the original intention was just to build a foothold on the mysterious island.

But after obtaining the druid's new ability, the somewhat obsessive-compulsive Second One still can't control his brain, and his mind has modeled the blueprint of a super city.

Although building a city is not a work that can be completed in a day.

However, it does not prevent the second first from planning the necessary infrastructure of various cities on the urban blueprint.

For example, a huge underground network or something, and even in order to facilitate future expansion and reconstruction, Second One has also adopted an urban modular design.

The most interesting thing is that it is far more convenient to use the druid's abilities to build a city than to use reinforced concrete and all kinds of large engineering equipment.

You don't even need to do anything by yourself, you just need to plan the structure and layout of the city as well as possible, and order the various plants to grow on their own.

Although relying on plants to "grow" a city out of thin air sounds a bit fantastical, and even if it can be realized, it will take hundreds of thousands of years.

However, under the special natural environment of the mysterious island and the double increase of [plant growth], this miracle is not impossible to achieve.

Not to mention, Two One also used magical druid natural magic such as [Command Plant], [Manipulate Plant], [Activate Plant], etc., to speed up this process.

Directly from the dense primeval forest, a large number of giant plants were moved as ready-made building materials, completing the infrastructure and general framework of the entire city, and the remaining details of the "construction" were handed over to the living plant city of Giant Tree City to complete by itself.

Under the concept of "three-dimensional forest, urban ecology, and environmental park".

The surface of Giant Tree City basically retains the original forest state, but it has been artistically planned and laid out to a certain extent.

For example, all the roads are basically the lines that make up the overall overview of the city, all the functional buildings are completely underground, and all the living buildings are all made of plants in the air.

As for urban greening such as street trees...... If the botanical city of Giant Tree City still needs greenery, it will be composed of all kinds of fruit trees, flower plants, and landscape plants.

It can be said that the entire surface of Giant Tree City is a huge aggregate of gardens, orchards and forest parks!

The so-called "three-dimensional forest" concept is the inspiration generated by Eryi after the construction of the "three-dimensional frame planting building".

The plants on the mysterious island are generally huge, and can be used not only as a building frame, but also as a building base or the building itself, hence this strange architectural style of "the house is built on the tree, and the garden is built on the roof".

All kinds of small flowers and plants, either in the form of filling soil, are planted directly on the branches of those giant trees.

Or simply in the form of parasitism, grafted on the façade of a plant building...... With the existence of [Wood Bending] and [Wood Shaping Technique], it is so easy to make those thick and unwanted big trees or ugly tree nodules that grow on giant trees and hollow out a flower bed that can hold the soil or something.

This also leads to the fact that every big tree in the Giant Tree City is topped with all kinds of strange plant buildings and all kinds of purple and red flowers.

As for "urban transportation", in addition to the underground space that has been reserved, the magic version of the subway that may be built in the future.

A large number of facilities such as the "Sky Vine Rope Bridge" and the "Slide Vine Cable Car" have also been added to connect different giant tree buildings, making it convenient for the residents of Giant Tree City to travel between various areas.

There are also urban lighting, urban energy and water supply, municipal garbage and sewage treatment...... These have been planned in the design of the second one.

If necessary, it can even be invested in the construction of the second phase of the dungeon of Giant Tree City.

With the experience of building the Imperial Spirit Underground Base, Eryi is already quite proficient in various underground construction techniques on the "Dungeon Construction Guide", and can directly apply them to Giant Tree City.

It's just that, for the time being, it's still in the planning.

First, there are some "plant building materials" among them, which are not available at hand for the time being.

Second, the main reason is that he doesn't have that need, he lives alone now, and he doesn't need much space at all.

In a short period of time, only 10%~15% of the infrastructure construction of Giant Tree City has been completed, but he is playing more with the construction of Giant Tree City as a real magic version of "SimCity", but he is not in a hurry to complete it.

Er Yi even felt very disgusted that even if he found a way to leave the Mysterious Island at that time, the Giant Tree City would grow into the shape he had planned, and if someone came to the Mysterious Island unexpectedly in the future and saw this magical plant city, would he be shocked?

It's a pity that before his prank even began, there were already some minor problems.

A large number of transplanted plants will not be affected even though they have the effect of [plant growth].

However, the rapid growth of plants also needs to consume nutrients, and the high density of a large number of plants directly leads to the overwhelm of the land, which is simply the fertility of the soil is not enough.

But the second one will go to find them in the middle of the hour?

If he could still connect with the outside world, he could connect with the consciousness split through the psychic channel, and prepare a large number of chemical fertilizers and other things to supplement the nutrients of the plants.

Or maybe the giant tree city is full of residents, and he can also accumulate some farm manure or something to water it, but now that he lives here alone, even if he eats more, how much can he pull...... Well, no matter how much he eats, he doesn't pull much.

In the end, he pondered and pondered, but it was Maruko who helped him solve the problem.

Maruko, like a spawn Krabirson, plucked a small mushroom cap from the enoki mushroom cluster on his head and threw it to the ground.

I saw that after this little fungus cap fell to the ground, it trembled and bred a few slender mycelium, and then relied on these flagella-like mycelium to pluck and pull the ground, rolling around on the ground.
