The mutant creatures attacked the city for three full days, and when most of the wild species left the city, the whole city gradually quieted down, and by this time, the whole city was already in ruins. Collapsed houses can be seen everywhere, there is hardly a complete glass to be found on the tall buildings of more than ten floors, in just three days, all corners of the city have been overgrown with weeds and vines, light blue fog continues to pour out from the door of space, spreading in all directions, and soon, a thin layer of fog is shrouded in all parts of the world.

The fog in the city is very light, just like the early morning in winter, the visibility is quite high, and the line of sight from a distance of one or two hundred meters is not affected, only the closer you get to the door of space, the fog will gradually get worse.

In three days, the Illusory Barrier that appeared in SG City had expanded to three million square kilometers, and the speed of this spread was still increasing exponentially.

…………

Chen Fan has been on the parallel earth for two days, and in the past two days, he has taken Yao Yong and Wang Qiang to search the entire city, trying to find a way to go to the Void, however, in addition to finding a lot of living corpses trapped in buildings during the search, he also met some survivors who came out to find food because of hunger, but the road to the Void is still clueless.

Today is the third day, early in the morning, Chen Fan woke up from his sleep, and suddenly found that the whole world had completely changed, the city seemed to be swallowed by green vegetation, weeds on the road drilled out of the cracks, destroying the road to the point that it was not in shape, the houses were also covered with vines, and the doors and windows could not be opened because of the entanglement of vines.

Chen Fan clearly remembered that just yesterday, the weeds around here were only ten centimeters high, but now they have grown to fifty centimeters overnight, reaching no more than an adult's knee.

"Hurry up, something is wrong." Chen Fan, who felt that something was wrong, hurriedly woke up the other people in the room.

"This ...... What's going on? It was fine last night, how did it become like this overnight? Yao Yong, who was still in a daze, immediately sobered up after seeing the scenery outside the window.

"I don't know, but there must be demons when things go wrong, I don't think we can stay here anymore, these plants will grow at this rate, and they will soon destroy the structure of the surrounding buildings, and then cause the houses to collapse. Moreover, since something has happened here, there must have been something wrong with our original world, and we have to find a way to return to our original world as soon as possible. Chen Fan said.

"Mortal cub, come and see." While a few people were talking, the mother, who had been cooking for everyone in the kitchen, exclaimed.

Hearing the shout, several people hurriedly turned around and ran towards the kitchen, in the kitchen, Chen's mother pointed to the food stored in the cupboard with a surprised face, which looked a little incredible, the rice and noodles in the cupboard were all covered with green mold, and the fresh food also emitted a foul smell.

"This, how can this be? I also deliberately looked at the expiration date when I took these things, why are they all broken now? Wang Qiang covered his nose and took two steps back, the smell of rotten eggs was unpleasant.

"It seems that not only the plants have changed, but also the microorganisms." Chen Fan said with a frown.

"In other words, why do all species mutate, but we humans do not?" Lin Wanqing on the side said curiously.

"Who said that human beings have not changed, aren't we just ......" Yao Yong's words were interrupted by Chen Fan before he could finish speaking.

"She's not referring to this, our evolution is caused by killing mutant creatures, and humans themselves have not yet appeared as mutated as those mutated creatures, as for the zombie-like guys we met before, I guess it was caused by some other reason." Chen Fan explained.

"So what do we do next?" Yao Yong asked.

"Pack up our things, let's get out of here first, and then find a way to find food on the way, although these things can't be eaten, but the vacuum-packed food should be able to be stored for a while longer." With that, Chen Fan walked into the room and picked up a half-person-tall military marching backpack and began to stuff things into it.

Not only that, but they also found two tents, and all the small equipment for survival in the wilderness, such as rescue ropes, sleeping bags, water bottles, etc., and of course, Chen Fan's favorite sapper shovels.

Since they decided to leave this place, everyone's movements are also fast, in fact, there are not many things they have to pack, but some cold-proof clothes, in less than five minutes, everyone has already packed, the gate has been wrapped by vines, Yao Yong cut the vines with a machete and pushed open the somewhat rusty gate, and the three men carried everything on their backs and walked out with Chen Mu and Lin Wanqing.

"Brother Fan, where are we going?" Looking at the jungle-like city streets, the five of them stood at the gate of the community and didn't know where to go.

Chen Fan thought for a while, then suddenly looked up at Yao Yong and said, "Do you remember when we were attacked by a bumblebee?" ”

"Yes, of course I remember, that's ...... Brother Fan, do you mean that we are going in the direction of the Wujiang River? Originally, Yao Yong was about to say that the experience could be described as nine deaths, but after seeing Chen Fan's expression of frowning at him, he quickly stopped and quickly changed the topic. Fortunately, Chen's mother did not find the clue.

"Well, when we first found out about the change in the original world, it was the group of bumblebees that suddenly appeared, and in the past two days, we have searched the entire city and found nothing unusual, so I guess the answer we are looking for will be in that direction?" Chen Fan said as his eyes drifted into the distance.

"But if you go to Wujiang, you will pass through Wangjia Village, if you encounter those things again......" Wang Qiang said with some worry, although he had evolved once, the experience of that day obviously still made him feel a little uneasy.

"That's no way, it's better to break or break through, it's better than being trapped here for a lifetime, there is not much time left for us, if the original world is the same as here, then our ontology is estimated to not last long, and, more importantly, if there is a shortage of food over there......" Chen Fan didn't dare to imagine that if the original world also had food mildew and accelerated, then his father and little aunt would also face a crisis.

"In this case, then I'll get a few motorcycles, Wujiang is more than 40 kilometers away from here, we can't always walk, even if we can, my sister-in-law and aunt are afraid they can't." Qiangzi, come with me ......" After listening to Chen Fan's words, Yao Yong finally realized the seriousness of the situation, and most importantly, it was also about his mother.
