"Here, it's really...... Pengcheng?!"

Because he was worried that he would drag others back, Dai Ochisis couldn't exert his strength with all his strength, so Ouyang came to the edge of Pengcheng alone.

He found that all the zombies surrounding Pengcheng were walking towards the same place, and Ouyang followed the zombies from a distance.

But the scene in front of him made him look confused.

Pengcheng has been broken.

There was not a single guard on the wall of Pengcheng, and although the flag fluttering at the entrance of the tower did not fall, there was no one to be seen.

It seems that when the soldiers and civilians of Pengcheng retreated from Pengcheng in a hurry, they didn't even have time to remove the flag.

There were a few unhealthy trees growing on the walls, and there were some vines crawling on the periphery of the walls, some of which looked like creepers, but when you looked closely, you found that they were actually parasitic pavilions, deeply rooted in the walls.

"The city guards are not good at taking care of the walls, no wonder they will be breached. Ouyang smacked his mouth and pursed his lips.

The parasitic plants on the city wall must be cleaned up in time, otherwise when the parasitic plants take root, it will cause huge damage to the wall, make the hardness of the wall decrease, and even directly split the wall.

Ouyang walked along the wall from a distance, and slowly saw a huge gap appear on the wall.

There is a huge crack on the city wall in the north of Pengcheng, three meters wide, showing an oblique trapezoidal shape, and the zombies around the nearly ten-meter-high city wall of Pengcheng continue to come to this gap, and pour into this gap in an orderly manner.

Yes, orderly, because of the double-edged tentacle zombies, it was indeed orderly, and everyone entered that gap unhurriedly.

Such a scene, like a group of gentlemen waiting in line and ready to eat, is much more qualified than those aunts.

Although Pengcheng does not dare to say that it is the most prosperous city, it is not an exaggeration to say that it is the city with the largest flow of people because of its geographical advantages of communicating between the north and the south, coupled with the wars and chaos and the reason why people come and go during the Spring and Autumn Period.

But now, the once prosperous Pengcheng has become a dead city.

Ouyang didn't go in and knew that Pengcheng was finished.

Being invaded by such a steady stream of zombies, even if Jingyang and Zhaoshe in Pengcheng were Jiang Shang alive and Xiang Yu crossed, it was basically impossible to resist them.

Not necessarily, don't be too pessimistic.

Maybe there are still some small groups of human forces in the city that are struggling, and it is still unknown to fight guerrilla warfare with these monsters.

Ouyang let out a long sigh, although he also knew that the probability of this kind of thing was almost very slim, he still had to give it a try.

Make a decision after at least one probing.

However, the purpose of the public loss class and the bear lieutenant people to come here is basically in vain, and in this case, it doesn't look like it can be left for their army and ordnance.

Ouyang looked at the tall Peng Cheng and wondered how he could go in and take a look without alarming the zombies.

................................................

Shouchun, who was busy forging new weapons, suddenly put down the work in his hands, glanced at each other, and said in unison:

"Have you ever seen Miss Zhuli?"

"No, I was going to ask you. Zhao Zhen wiped the sweat from her face and said.

"Isn't Shi Yiguang often with her? Did you say anything?" Sun Wu looked at Fan Li.

"Yiguang didn't know that recently she was studying Changsangjun's ancient books and wanted to be a medical girl. Fan Li explained.

"Tsk, it always feels wrong...... Chang Sangjun touched his somewhat wet beard, wiped it with a towel, and then drank a big bowl of herbal tea.

"Forget it, don't think about it so much, what can a weak woman do, I guess it's to collect medicine. Sun Wu waved his hand, indicating that he didn't want to use his brain.

"It makes sense, after all, everyone is not a child anymore, and there is no need to manage others all day long. Fan Li nodded.

"Keep knocking, this bone is too tough, I use so much force, but it's only a little deformed. Sun Wu shook the half-human-high sledgehammer in his hand and complained.

"Just use a rammed earth tool. In this way, it will take several generations to knock it down. Chang Sangjun looked at the ribs in front of him and couldn't help but say.

"Then let's use a rammed earth wooden hammer to deform it. Xue Zhu nodded, and as a weapon master, he agreed to this plan.

................................................

Ouyang did not alarm those zombies, but went around the city wall to find a place where there were fewer zombies and it was convenient for him to go up, and used his physical fitness far beyond ordinary people to start and jump, directly climbed over the wall, and finally fell smoothly into Pengcheng City.

Ouyang, who had already jumped in, didn't notice that those zombies seemed to be stupid and didn't react to Ouyang's movements.

When he saw the huge crack, Ouyang had already imagined that maybe Pengcheng was a ruined painting, or scorched earth all over the ground, or it was full of blood and smelly.

But the scene inside made him feel like he was going to the wrong door.

This large city, which has a history of at least 1,000 years and 100,000 households, has now become a relic from a distant time and space.

No, it's still too modest to say that the ruins are just another time and space, okay?

For a moment, he wondered if he had become colorblind.

Because this overwhelming green poured into his eyes, making him a little dazed for a moment.

Gan, it's too green, how can it be so green, how can it be like this?!

The bright green made him suffocate a little.

The bluestone brick walls were covered with vines, and every house grew towering trees that broke through the roofs, and the ground was covered with a thick, soft, unknown dark green moss.

As soon as you look up, you can see the huge trees that cover the sky, and the sunlight can only shine through the tiny gaps between the trees, and the ground is shining in speckles.

It's a little eerie, and it doesn't feel too good, especially after the snow, and such a scene makes Ouyang feel a little cool.

Of course, it's just that you can feel the temperature low, not really cold.

But here, it's really green......

When I used to write essays in elementary school and went to the Chenshan Botanical Garden, I simply used the short word "sea of plants" as an exaggerated description.

But I didn't expect that this is no longer a question of exaggeration, this is a spectacular phenomenon that can't even be described by a short word like "sea of plants"!

Am I crossing over?

Ouyang stood in place and didn't dare to act rashly, carefully looking at some of the things around him.

It seems like no creature has set foot here in a long time.

The moss is thick.

He crouched down and touched the moss, which felt more like some kind of moss-like plant, because it couldn't have grown so thick.

Of course, it could just be that he was unheard.

Ouyang stood up, raised one foot, and gently stepped on the moss, and then left a dark footprint on the position where he had stepped on it.

The moss is soft and comfortable, as if you are stepping on a carpet.

It gave him the urge to lie down.

He felt that the moss here must be a little happier than lying on the snow.

The oxygen content in the air appears to be extremely high.

Ouyang took a deep breath of the air around him, and immediately felt a clear mind, and then, there was a slightly uncomfortable feeling.

It seems that the body instinctively resists such air.

If you take too much oxygen, then the body will accelerate oxidation, which is equivalent to the body is accelerating aging, so it is normal for the body to resist it.

Ouyang adjusted his respiratory organs to reduce the amount of each breath he took to solve the problem of peroxide in his body.

Although he has the parasitism of Diochisis, and the "evolutionary divinity", and the realm of heaven and man, which seems to be useless in this world, he can live a little longer than the average human.

But it is also very limited, at most it will only look like two or three hundred years.

Life is your own, of course, you can save it.

"Daiochis?" Ouyang shouted softly.

Daiochisis and Ouyang had a heart-to-heart, and immediately understood what Ouyang meant.

"Your Excellency, the air here contains thirty-five percent oxygen. Deocisis quickly gave a number.

It was parasitic on Ouyang's body, and it knew Ouyang's physical condition very well, so it naturally knew the oxygen content of Ouyang's inhaled body.

Under normal circumstances, the oxygen content of the air is 21 percent, and 35 percent has reached the peak of prehistoric times, that is, before the birth of humans, and even before the dinosaur period, probably from the end of the Carboniferous period to the beginning of the Permian.

At that time, the oxygen content was extremely high, and then under that high oxygen content, many giant insects were born.

Of course, with such a high concentration of oxygen, fire is also essential.

"This oxygen content is a bit ridiculously high...... Ouyang asked a little puzzled, "Even if all the carbon dioxide in Pengcheng can't make so much oxygen, right?"

The carbon dioxide in the air is about 0.3 to 0.4 percent, which of course cannot reach such a terrifying level.

And what's very weird is that it looks like all the creatures here are dead, except for all kinds of green plants, just a bunch of mushrooms that don't know their names and don't look like they can eat.

They come in a variety of shapes and colors, and most of them grow in crevices in stones and under large trees, where there is no moss.

Occasionally, you can see some huge fungus on the moss, with a large umbrella cover, the size of a washbasin, which looks like a small stool, reaching up to a person's legs and knees.

The mushrooms weren't as bright in color as the small ones, but in the shadows, they seemed to glow with some kind of faint fluorescence.

But because it was too weak, Ouyang could only see a rough idea.
