Shen Feng and Xu Xing were standing in the city, ready to take a look at what was in the sky, was it a bird or a bug? But at this moment, the manhole cover of the sewer in the distant city was opened, and then a small figure came out, waving at the two people continuously.

The two of them looked in the direction of the sewer manhole cover, and found that it was actually a child, who seemed to have given bread in the first place.

For the orphans, they were accepting help, and they would definitely remember each other in the future, and now they were waving at Shen Feng, and there was an anxious look on their faces, obviously very excited, worried that the two of them would be in danger.

"What do we do now?" Xu Xing couldn't help but ask.

In fact, the meaning of this sentence she asked was very simple, I wanted to know whether I was going to fight or flee next, after all, there were children who found a way for them to escape, although it was not difficult to fight, but I didn't know what the danger was, at this time, there were orphans who kindly reminded them, how could they be indifferent?

Shen Feng thought for a moment and said, "Although I also want to know what will happen here, but now let's follow this little kid, I think we gave them bread before, and now they won't harm us, right?"

Xu Xing also nodded hurriedly, and then the two of them walked in the direction of the sewer, and they couldn't understand the words from these children's mouths, but as long as they looked at his gestures, they could still understand what they meant, they were calling the two people on their side, and let themselves hide in the sewer with them.

When the two of them came to the edge of the sewer, they saw that there were other people here in the sewer, and there were many adults hiding in the sewer, but these people obviously did not mean to rescue Shen Feng, and the courage of a group of adults was much smaller than that of a few stray children.

"It's so dirty, are we going to hide in here too?" Xu Xing was stunned after seeing the situation in this sewer, because the environment inside is too dirty, the city itself is in the rainforest, and it is also established on the edge of the river, there is sewage at any time, and there is sewage in the sewer now, which can be drowned to the position of people's ankles, Xu Xing is also a girl, always loves beauty, and now after seeing the environment in the sewer, she immediately began to resist.

Shen Feng said, "If your body is dirty, just wash it, now the danger is coming, if we are still picky at this time, we will be forced to fight!"

After Shen Feng said this, Xu Xing looked back at the huge black shadow in the distance, now this black shadow has become bigger and bigger, if he continues to hesitate now, he will be attacked by these unknown things soon!

So Xu Xing could only shake his head helplessly, and then jumped down, and Shen Feng at this time also jumped down together, as for the little boy who reminded them, he struggled to cover the manhole cover.

It didn't take long for a fierce sound to come out in the outside world, Shen Feng was very familiar with this sound, wasn't this the sound of the insects flapping their wings when they were flying? In other words, it is not a bird that flies in the outside world, but a flying bug.

"Could it be that it's not the birds that are destroying the city, it's the insects?" Shen Feng already had a question in his heart.

Then, Xu Xing turned on the flashlight in the sewer, and finally illuminated the dark space, in this dirty sewer, there was stagnant water and silt everywhere, and there was a stench everywhere, this smell was completely irresistible, it was completely uncontrollable to drill into the nose, Xu Xing could still vaguely smell methane.

"It stinks, these people can hide in such a place all the time, it's really unbearable!" Xu Xing said to Shen Feng.

"What can you do if you can't bear it? If they could get out, they would have already gone out!" Shen Feng also said helplessly.

If the good fruit is not hiding in the dirty sewers, most of these people have been killed by the enemy now, and only by hiding in a place where others can't find it can they survive, ordinary people are so useless in this world, and after getting out of a comfort zone, it will become very useless, so human beings can only live together.

"Two Abilities, you're finally back, but it's a pity that we didn't keep the glider!" At this moment, a man in the crowd in the sewers stood up and shone a flashlight, only to realize that it was Frankie.

After Shen Feng saw this guy, he already understood that he was now able to communicate with the people here, after all, now that he had an interpreter, it was easier to ask what was going on in the city.

"Come here, I have something I want to ask you, you give me a careful answer!" Shen Feng hurriedly said.

"I don't know what you want to know, I'll tell you everything I know!" Frankie replied quickly.

"Now I just want to know why your city is the way it is, and it shouldn't have been destroyed!" Shen Feng raised the question in his heart and wanted the other party to answer it.

"In fact, we didn't think about this at all, when the day of the disaster, we were completely confused, some soldiers picked up guns and came to the city wall to resist, some people scattered and fled, but in the end there were very few people who survived, we were lucky enough to hide in the sewers, so we escaped the disaster, but now we don't dare to go out every day, because once we go out, we may be targeted by monsters." Frankie said in great pain.

It turned out that five days ago, Manaus had already encountered a crisis of destruction, when a huge insect suddenly appeared in the sky, and it was found that these insects in the sky were huge dragonflies, and the wings of these dragonflies were spread out, and they could be three meters long and wave to make a terrifying sound, and these insects could take humans directly to the sky after catching them, and the power was really powerful.

If it was just insects in the sky, then the people in the city would not be too worried, after all, as long as they hide in the house and close the doors and windows, these insects will not be able to catch them out of the room, but at this moment, many giant centipedes appeared in the forest, and these centipedes are larger than the dragonflies in the sky.

These centipedes have very thick waists, each centipede is at least fifty or sixty centimeters thick, crawling in from outside the city and making a squeaky sound, it looks very terrifying, there are many insect feet on both sides of the centipede's body, these insect feet scratch on the floor and make a piercing sound.

Therefore, after the centipede appeared, it also brought a sense of fear to everyone, but at this moment it was not enough to destroy the city, the most terrible thing is that these centipedes will spray acid, which can corrode the walls, so the hard building is corroded by the foundation, and then collapses, people no longer dare to hide in the room, so they choose to leave the room and flee into the distance.

When people fled from the houses one after another, it was too late for them to leave the city, because there were huge dragonflies in the sky that were always catching people, these dragonflies themselves were meat-eating, but they only ate small insects before, but after the body became huge, they began to eat people, after all, humans are pure food in their eyes, and there are huge centipedes on the ground are also crawling, as long as they encounter humans, they will spray acid, which can directly corrode the flesh of humans.

In this case, the people in the city are trying to escape, but in the end, there are very few people who actually escape from the world, and most of them have been killed by the dragonflies that suddenly appear in the sky, these dragonflies have huge bodies, and they are very cruel.

There are also people who have been hiding in their homes, but eventually died under the collapse of the house, after all, when the foundation of each house has been corroded by acid, these houses can not continue to stand, but will collapse with a bang, centipedes like to drill into the cracks of the stones, when the house collapses, it is not the rescue team that is looking for these humans, but a giant centipede.

Humans hiding in houses are inevitably eaten by centipedes, so I have been in the past few days, dragonflies and centipedes appear in the sky above the city every day, and then eat humans, a city that was originally quite good, has now become a ruin, and most of the surviving people in the city have hid in the sewers.

"So much has happened, I didn't hear of such a huge insect when I was in other places before, but it turned out to be in the Amazon

Giant bugs, what does this mean? Do insects also have atavistic phenomena?" Shen Feng said to himself in a low voice.

In ancient times, in fact, there was a period of time when the oxygen concentration on the earth was very high, this is because the explosion of cyanobacteria in the ocean was also relatively high, and the oxygen concentration on the earth at that time was much higher than now, so after there was enough oxygen, the Zerg began to develop, and many insects have evolved, and their evolution direction is to have a larger body size.

When the size of the insects has increased, then they have a stronger ability to hunt, and some insects can even prey on small mammals, such as rats and rabbits, which were the food of the insects at that time.

Fortunately, in the later changes in the earth, the concentration of oxygen decreased rapidly, so the insects had to shrink their own system in order to survive, in order to reduce the consumption of oxygen, after all, without oxygen, these insects would also suffocate to death, so the later mammals had a chance to develop.

As a result, in the apocalypse, due to the emergence of many mutated cyanobacteria in the earth's oceans, these cyanobacteria can produce more oxygen, which directly leads to the increase in the size of various animals, and the largest impact is the number of insects, these insects themselves are restricted by the concentration of oxygen, so they can not obtain a huge size, but now they can easily obtain oxygen, and the size will increase instantly.

As these bugs grow in size, they also begin to prey on humans, eventually having the ability to easily destroy a city in the Amazon, which is quite terrifying.

"Brother Shen Feng, what should we do next? Are you going to kill these bugs?" Xu Xing couldn't help but ask Shen Feng.

"We've been out for almost three and a half months, and for such a long time, I don't know what's going on in China, so let's find a chance to leave now, as for the Amazon region, don't worry about it, anyway, this is someone else's territory." Shen Feng told Xu Xing his purpose.

"But there are so many people trapped in the sewers here, and if we don't leave with them, they will eventually die and suffer heavy casualties, and maybe not a single one will survive, and we can't sit idly by!" Xu Xing said to Shen Feng seriously.

"Don't be nosy, whether these people survive or not has nothing to do with us, will we have to lend a hand when we see someone in need in the future? In this case, the world is full of people in need, and we simply don't have the energy to take care of them!" Shen Feng explained to Xu Xing.

"The Buddhist scriptures have clouds, save people's lives, and win the seventh-level floating slaughter. Therefore, saving people is to accumulate virtue and do good, and human beings are social animals, and saving others is also for the better development of society, isn't it?" Xu Xing said to Shen Feng.

"You don't have to bother, you can bring it if you want, but I won't protect them, if you want to protect them, you can do it yourself, I'm afraid you won't be able to take care of it at all." Shen Feng shrugged and said.

Originally, Shen Feng wanted to take Xu Xing and fly away directly from the sky, and he couldn't carry too many other people at all, but if he only took Xu Xing, he was very sure, but now it seems that he can only escape from the woods with everyone, the Amazon rainforest is full of many dangers, not to mention the beasts and poisonous insects, just say that these dragonflies in the sky that may appear at any time are in great danger, and if they flee the city with so many hundreds of people, they will definitely be dragged down in the end.
