He continued to fly, continued to go deep, and he must go deep into a terrifying place, a place full of ferocious beasts.
At this time, he is extremely far away from even a safe city where human beings go deep into the secret realm.
This distance is roughly equivalent to his journey from the southernmost point of the southern region of the Wuzhou Realm to the northernmost extreme cold secret realm of the northern region.
What people use to define the weight of loneliness is about distance.
This time, he really went too deep. He encountered all kinds of bizarre phenomena and saw all kinds of weird places over and over again.
Another day passed and everything changed.
The air here is already extremely thin, the sky is pitch black, and the stars are unprecedentedly clear.
It was as if the atmosphere covering the sky above his head had disappeared.
Some people say that the sanctuary exists in a mezzanine in the middle of the plane, and it does not belong to any plane, nor does it belong to any spatial node.
It's a separate little crack.
And in this ghostly place, Xiang Nan saw more things that he had never seen in his life, and things that had never been recorded in ancient documents.
At this moment, the area he was in was still a jungle, but the trees in this jungle were extremely strange.
According to Xiang Nan's own knowledge theory, these trees should be called inorganic life forms.
Out of some weird natural law, the trees here are actually made of metal.
People's understanding of life is always limited to specific scenes and media, such as water, wood, soil, and so on.
It has never been thought that metals also have life.
But Xiang Nan did see it here.
What he saw was a kind of metal, just playing with wood.
He stroked the trunk of a tree and marveled at the miracle of nature.
Nearly two-thirds of the area of this tree is made of pure metal, and the other third is made of wood, as if metal and wood are perfectly combined.
With a giant knife, he carefully cut open the trunk, and found that inside the metal trunk, there was still liquid slowly transporting nutrients.
"This thing is really strange. Is this called an inorganic life form? It's quite vivid."
Xiang Nan said this subconsciously, out of habit.
But after a long time when no one responded, he suddenly recalled it, smiled, and said: "What's the matter, the big snake has obviously stayed in Dragon Valley, but I haven't been used to this kind of thing for many days."
He picked a fruit from the tree, and that fruit was also two-thirds metal and one-third flesh.
It's a real jungle of steel.
The miracle of life is quietly growing here in an unknown way.
He continued to move forward, and after flying through this vast jungle, the trees that appeared in front of him had completely become real pure metal.
Metal is not an organism, but Xiang Nan really saw the vigorous vitality in those metal trees through Lei Guang's eyes.
And even more peculiar situations followed one after another.
Here he began to discover life forms other than plants, some insects made of pure metal.
A small ladybug landed on Xiang Nan's shoulder.
He pinched the ladybug and held it in front of his eyes. The whole body of the ladybug showed an iron blue color, and when he squeezed it with his hands, there was a crunching sound of metal being crushed.
The ladybug was crushed, and a pungent liquid flowed out of its body. This liquid turned out to be a kind of liquid metal, that is, the blood of the ladybug.
Right in front of this pure steel forest are two towering mountains.
These two mountains are like the barrier of the sky, and also like an ignorant human being. After walking to the end of the world, he suddenly discovered that the farthest part of the world is a wall.
It also gives people a feeling of nothingness outside the walls.
It's just that behind those two "walls", there is an unbelievable fluctuation of group vitality.
"In there, there must be a large number of strange creatures, and they may even be eternal beasts."
Xiang Nan said something to himself, and immediately took off, flying towards the gap between the two mountains.
But what surprised him even more was that here, he actually discovered human beings, as well as relics that looked very much like human beings.
Between the two giant mountains is a huge stone gate, the stone gate is towering, and two flying dragon stone carvings are carved on the top of the gate.
On both sides of the stone gate, there are also two amazing sculptures that are so huge that they are three thousand meters away.
The sculptures are two burly warriors, each holding a strange weapon, which is somewhat similar to a brush-shaped weapon.
The other sculpture is bent over, as if it is about to pounce at any moment, and it also holds a strange weapon in its hand, which looks like a... dragon!
Xiang Nan has never seen such a thing as turning a weapon into a creature.
The shape and structure of human weapons are very simple, usually for the convenience of hacking and hammering. Few people make weapons into the appearance of certain creatures, which is obviously not flattering.
Could it be that the figure depicted in the sculpture holding a dragon-shaped weapon is not a dragon-shaped weapon at all, but a real dragon
Looking at this stone gate, Xiang Nan can't imagine how long it has existed here. It seems that it is older than the lost civilization on the yellow planet.
The known life forms of human beings can be deduced from fossils, and they can be estimated hundreds of millions of years ago. They are some very ancient creatures, some of which are similar to half-dragons, and they are usually huge in size.
And the stone gate in front of him is even older than those fossils, maybe billions of years old.
What shocked Xiang Xiangnan was that he heard whispers coming from the gap between the two huge stone doors.
Xiang Nan's heart was all in his throat at once.
Are there still ancient humans living here
Could it be that he is about to see an unknown civilization soon
Cautiously, he squeezed in through the gap in the huge door, and took a peek inside, but after a look, he was disappointed again.
It turned out that they were not descendants of ancient civilizations at all, but modern warriors.
Hundreds of masters dressed in modern costumes, even wearing the emblem of the Four Emperors Guild on their chests, were sitting in a wide hall, some were talking, and some were resting with their eyes closed.
The realm of these people is very high, usually around the ninth level of martial saints, and even a small part of them have the realm of the first level of heavenly tribulation.
They also found Xiang Nan, and they all looked at Xiang Nan with curious eyes.
Seeing that Xiang Nan was a first-tier martial artist, everyone lost interest and went back to doing their own thing.
A beautiful woman came over curiously, and said, "You little boy, how did you get to such a deep place? Are you lost?"
"Damn it, how did you come here this way, didn't you get killed by a ferocious beast?"
It is a miracle in itself that Xiang Nan can come to such a deep place, but more people are indifferent to Xiang Nan's arrival, which shows that there should be something more concerned in their hearts that is attracting their attention. What exactly is that, Xiang Nan still has no way of guessing.
