Qin Di took out the star map, handed it to Tongtianzhou, and then turned on the automatic navigation and flew towards the legendary spirit world.

A long space trip, cold and lonely, without even a sound.

Fortunately, Qin Di has a small peach tree as his companion, and he also has all kinds of spiritual treasures and immortal weapons, so he can talk from time to time, so no matter how long the journey is, he doesn't feel lonely.

Furthermore, as a monk, a single meditation can last for years, so he sits in the Heavenly Boat and looks intently at his own cave world, and before he knows it, time has passed.

Since he advanced to the ninth order earth immortal, there are already all kinds of spirit grasses and animals in his cave sky, not only lower animals such as mosquitoes, but also large animals such as cats, dogs, cows and tigers, but there are no primate creatures, especially no one, who can survive in it for a long time. As long as there is a primate, it means that he has stepped into the immortal.

Advancing again and again, pulling the immortal spirit vein again and again, his cave heaven has expanded many times compared to the beginning, and the total area is no less than that of China in his previous life.

In the future, when he becomes a high-level spirit immortal, he will be able to carry a large number of humans in the cave sky.

If one day, he becomes a heavenly immortal, and he can also manifest the cave and turn it into a real heaven and earth, a world that is not small.

Qin Di suspected that at least some of the so-called Three Thousand Great Worlds, Three Thousand Middle Worlds, and Three Thousand Small Worlds might have come from this. Those with low skills, such as the Earth Immortals, can only leave a small Cave Heaven, and the Spirit Immortals with slightly higher skills can leave behind larger small worlds, and if they grow into Heavenly Immortals, or the Great Power of Golden Immortals, they may leave relatively medium-sized or even large worlds. In this way, the external world is constantly dying out, and new worlds are constantly being born, and the whole universe becomes rich and colorful.

According to the guidance of the star chart, the boat flew continuously for three months before it began to slow down.

Qin Di looked around and saw a blue planet appear directly in front of him.

This planet is very large, at least thousands of times the size of the Earth in the previous life, and more than ten times larger than the Circular Wilderness World.

Therefore, Qin Di has reason to suspect that on such a planet, gravity will also increase, and the reason why such a planetary plane is called the spirit world is that in addition to its extremely rich aura and extremely rich materials, gravity will also become very strong, and only people with higher skills, such as monks above Buxu, can live on it. Otherwise, Patriarch Liu Huayang would not have made a hard and fast rule and only allowed the monks of the Four Holy Sects to enter the spirit realm.

Qin Di preferred to believe that it was not because of the limitations of the teleportation array, but because he thought that the requirements of the spirit world itself, if the skill was too low, it would not be possible to survive in the spirit world.

Of course, there may also be low-level monks in the spirit world, but they must have grown up in the spirit world since childhood, and have adapted to the local living environment from the mother's womb, otherwise the extremely strong gravity alone may make people unable to adapt.

Flying further, Qin Di could already clearly see the five continents on the planet of the Spirit Realm, except for the central continent showing pale yellow, the remaining five continents were cyan, red, white, and black. It is said that only the central continent is inhabited by monks, and I don't know what the surrounding four continents are like, so why are there no human settlements?

According to Qin Di's preliminary speculation, the reason why no one has settled in the surrounding continent may be because there is a single five elements, and as a human being, no matter what kind of exercises one has cultivated, there must be a physical body after all, as long as there is a physical body, there will be five internal organs, and if there are five internal organs, it is inseparable from the five elements, gold, wood, water, fire, and earth, everything is indispensable. To give a simple example, even if you are a fire cultivator, you can't have blood on your body, and if you have blood, you will have water, which is just an example of the coexistence of the five elements. If you want to pursue the ultimate, as long as you want the fire element, not several other elements, then you can only abandon the physical body and practice alone with the primordial spirit. However, such monks are rare, because after the primordial spirit leaves the physical body, there is a great possibility that he will face a fall and will not be able to exist in the universe for a long time.

Seeing that he was about to reach the spirit world, in order to avoid unnecessary trouble, Qin Di hurriedly put away the Tongtian Boat and all kinds of immortal weapons, and took off the high-grade hidden algae robe on his body, so he put on an ordinary magic robe and flew towards the spirit world.

There is also a layer of heavenly membrane on the outside of the spirit world, Qin Di is wearing heavenly soul glasses, and he can see that the heavenly dao laws here are more complicated, among which the high-level laws are at least five or six times more than those of the original world, and there are even a few purple heavenly strips, thin lines composed of various laws, as if forming a net, densely surrounding the spirit world.

Fortunately, this celestial membrane also seems to have spiritual intelligence, it will only block the entry of heavenly immortals, but it will not block ninth-order earth immortals like Qin Di.

The way of heaven is to make up for the deficiency when there is more than is lost. Therefore, a high-level monk like a Heavenly Immortal cannot enter the Spirit Realm at will, just like a Spirit Immortal like Huayin Shaojun cannot enter the Origin World at will, this is the protective effect of the Heavenly Dao on all worlds.

And a weak person like Qin Di can enter the spirit realm because he belongs to the object of protection. The number of Dayan is fifty, and there are nine out of forty, and there is one that has escaped. Heaven will always leave room for improvement, so that the Heavenly Dao will not become rigid.

As a newcomer who flew up from the Wasteland, Qin Di easily entered the Heavenly Membrane of the Spirit Realm, and the thin lines of the Heavenly Dao Law would automatically circumvent it, and none of them touched him, let alone the Heavenly Thunder landing on him.

Because of the strong gravity of the spirit world, he fell rapidly from the sky, like a pop, sliding to the ground.

There are no immortal officials on the ground to come to check, it seems that the huge spiritual realm is used to this, every spirit immortal has a strong pressure, and he only knows to stare at the higher-level existence on his head, who will pay attention to a little shrimp like Qin Di?

Qin Di looked around and found that there was a forest around him, probably because of the abundance of spiritual energy, the big trees had grown to a hundred zhang high. There are still many shrubs under the trees, so dense that it is impossible to step on.

Therefore, he jumped to the treetops, took out a third-order Spirit Treasure Flying Boat, chose a direction at random, and flew forward.

This forest was very large, and he flew for more than an hour before he saw an immortal sect appear on the top of the mountain.

Qin Di cautiously came to the front, chatted with a low-level disciple, and quickly obtained relevant news.

The place where he landed was located in the southeast corner of the Central Continent, far away from the northeast corner where he wanted to go!

He then continued to fly north in a flying boat.

Two days later, he saw a large castle with the words "Aoki Castle" written on a plaque at the gate of the city.

Qin Di handed over a piece of spirit crystal and entered Aoki City.

Aoki City seems to be dominated by wood monks, and some of them are demon cultivators made of plants, but fortunately, there is still more harmony between humans and demons, and there is no conflict in broad daylight.

The little peach tree rarely appeared, turned into a beautiful and colorful woman, and walked on the streets of Aoki City.

There are many shops on the street, and there is a constant stream of customers.

The two of them walked all the way, and Qin Di found that most of the products in the store were wood-based spiritual materials, spiritual treasure magic weapons, some cherished spiritual grasses, and even some fairy grasses.

Qin Di purchased a batch of spirit grass, because his cave heaven was still expanding rapidly, and he needed to add a variety of spirit grasses from time to time, and these spirit grasses could also promote the improvement of his skill by advancing in his cave heaven.
