Seven months have passed since the cataclysm, in fact, to be precise, since the Baimang incident last year, the changes have begun, but they have not been revealed, and everything has only been revealed after March and appeared in the eyes of ordinary people.

After the cataclysm, the trees and plants on the earth have become taller and stranger, all kinds of poisonous, non-toxic, large, small, and strange!

As the number of trees and plants increases, there is also the intense photosynthesis that occurs as they grow rapidly. As a result, the oxygen content in the air slowly increases, and the increase in oxygen represents a huge increase in the size of the organism! In this way, the proportion of oxygen content in the air in the next few years may reach the proportion of oxygen content in the Jurassic era.

Although the flora and fauna have become huge now, they are still nowhere near as huge as in the Jurassic era.

In the land of China, the largest and tallest trees are still the twenty-four supernatural trees, seed trees. In the past few months, the tree, which was originally more than 1,000 meters, has slowly grown to more than 2,000 meters, and the height has even reached 3,000 meters! The huge canopy of trees is lush and obscured by its shadows for a radius of six or seven kilometers.

And beneath the seed tree is the place where humanity can survive. Around several towering trees, humans have built eight giant cities at the roots of the trees.

Of course, the construction of the giant city was only a little bit of human power, but most of the buildings were built on the seed tree.

Leaning on the formwork in the seed tree, with a slight modification, a high wall around the seed tree was built, the wall is 100 meters high, it looks like a hill from a distance, standing quietly around the giant tree, the closer you get, the more you can feel it, the majesty of this huge city wall, standing in the corner of the wall, looking at the sky, the sky is divided into two halves, one is the wall, the other is the white clouds that have not dispersed for a long time!

Through a few large trees that obstructed their view, the two of them saw the huge wall.

"Brother, this wall is so tall and big! It's like in a cartoon! Tall and big!! I saw a little girl in a delicate costume, tilting her head to the man who was pulling her and wearing loose clothes.

"Yes!" Listening to the little girl's words of amazement, the man turned his head and whispered to the little girl.

Leaving the forest, in fact, it has not yet reached the vicinity of the city walls.

Between the city wall and the forest, there is a huge open space more than 1,000 meters wide, which is like an encirclement, separating the city wall and the forest.

The whole area is yellow, and perhaps because of the rain and the movement of people, the whole yellow clearing is terrible hard. And it's strange to say that in the land full of all kinds of plants, there are still places where there is not a trace of plants, and I don't know why, and this is one of the secrets that people talk about in private.

Although the reason is unknown, it is speculated that it must have something to do with the tree.

In fact, they guessed correctly, the formation of this clearing has a huge relationship with the seed tree. Under the investigation of Cheng Bin's spiritual power, countless tiny whiskers grew densely under this yellow clearing, intertwined horizontally and vertically, forming a huge network.

And under the shroud of this network, all creatures that are about to sprout are killed by it and absorb the nutrients of the seed corpses!

Of course, he, that is, this huge network, actually has another role, his main role, but this role will be seen in other times, and it cannot be seen now.

Two figures, one large and one small, came out of the dense forest in the distance, and slowly approached the huge city wall step by step. The closer they got to the city gate, the flow of people gradually increased, gathering in groups of threes and threes, or lining up to enter the city from a jungle with wounded loads, or going out of the city gate, holding all kinds of weapons and carrying all kinds of emotions, carefully entering the endless wild forest.

But these are the people who go out of the city to hunt, or who come back from hunting in the jungle. After seeing those two figures, the already sparse flow of people tacitly dispersed an avenue for them to pass. And all of them showed a series of expressions of reverence and respect on their faces.

"Didn't you see them!"

"See. Do you know? ”

"No, I don't know, but I know one of them must be strong!!" In the crowd, two people dressed in various beast skins and furs stood in place and watched the two people, one big and one small, talking.

Smack-

One of the slightly shorter teenagers slapped the man on the back of the head.

"Don't you say I know, I don't see what they're wearing? I'm not blind, I'm not stupid! ”

“.... Yes, yes, yes!! I don't know who saw it...."

"What do you see? What happened? ”

Just as the tall boy was about to say that, the short boy turned around expressionlessly, and suddenly the tall boy closed his mouth.

"Hey, I don't know when I will be able to break through the second order, I can break through the second order and release a little bit of energy, and after the energy is released, I can protect my clothes, and if I can protect my clothes, I don't have to remake my clothes after every battle. That's..."

"Then you're going to be on the front line at every beast tide!!"

The short boy interrupted the fantasy of the fellow boy with a single sentence.

"Forget it...."

As if thinking of the dangerous scene of every beast tide, the tall young man said weakly.

"Forget it, I won't. I want to break through the second order quickly, fresh clothes and angry horses, even if I die, at least I leave my name, I don't want those unknown warriors who died can only be seen on the monument. ”

"Yes, yes, my big hero, let's go, don't go and go to the city to exchange spirit coins for resurrection bamboo, after the resurrection bamboo is robbed by others, we don't have spirit coins to exchange for food today!!"

Looking at the order restored by the two of them after entering the city, the tall young man turned around and walked towards the dense forest, saying as he walked.

"Ahh

The boy who was pulled back from the beautiful fantasy walked back and replied.

......

As soon as he entered the city gate, Cheng Bin saw countless neat bungalows, yes, bungalows.

It is a three-meter-high house with a flat roof.

In fact, under the investigation of Cheng Bin's spiritual power, this survivor city has a scene that was unknown in peacetime, that is, the rooms where people live are underground, which means that the bungalows exposed on the ground are the top floors of a building.

The entire city was hollowed out of the ground beneath the city walls, and after the land was emptied, a huge city was built beneath the surface for the survivors to live and survive.

The rooms that are exposed to the surface can be used as entrances to the underground city, and can also be used as shops to meet the normal needs of people's lives.
