After rescuing the old man Guo Cheng, the group turned around and sneaked towards the base city, stopping and advancing along the way, and under the guidance of Ye Chen's seemingly unintentional but intentional guidance, they avoided many powerful monsters.

Buzzing......

Suddenly, the sound of wings fluttering sounded from the front, and everyone who was walking in the ruins was startled, quickly stopped, hid in a building, and lurked.

Then, everyone saw that the sky above had darkened, and countless "buzzing" sounds came quickly, flying into the distance.

Ye Chen looked up, and immediately saw a large group of evolutionary mosquito monsters flying by, densely packed, numbering as many as tens of thousands, each of which was five inches long, with sharp mouthparts harder than steel, flying all the way, there were zombie dogs and zombie rats on the ground rushing from the dark corners, all of which were pierced by the sharp mouthparts.

Behind this group of mosquito monsters, there was a dark cloud removed, and when I looked closely, I found that it was a large strange monster, with a huge head, like a watermelon, with a mouth that was not horizontally long, but vertical, with hideous teeth and claws as sharp as knives.

"Zombie flies!" Ye Chen's eyes froze, this large area of monsters with a number of more than 100,000 turned out to be zombie flies, looking at their ferocious appearance, they were chasing and killing this group of mosquitoes!

"Hum—"

The zombie flies swarmed up and caught up with the mosquito monsters, and the two sides became entangled and fought.

Ye Chen and the others, who were hiding in the building below, closed their breaths tightly, for fear of alarming these monsters, otherwise they would definitely die without a burial, you must know that although a mosquito monster only has a first-level physique, it is only tens of thousands of impacts, which is definitely more powerful than rocket artillery, and even the city wall will be bombarded and pierced at once!

And the zombie fly, with only the physique of five people's strength, these two monsters were as weak as ants in the previous peaceful era, and even stronger than ants, and they were more difficult to kill. But after the end of the world, the ant evolves a little bit, and its strength will increase by 400 times, in terms of strength, it is far stronger than flies and mosquitoes, and in its own defense, it is still very fragile, only about three people, but it has a layer of carapace on the outside, and with evolution, it has been strengthened many times, adding a lot of defense, so it is quite difficult to kill.

To put it simply, an ant only has the eyesight and hearing of three people, but in terms of strength, it has increased by 400 times, reaching the strength of 120 people! To a certain extent, strength also affects the speed of action, so the speed of action of ants can be comparable to that of monsters from level 6 to level 8.

Who would have thought that a level 12 ant, with eyesight and hearing, would only be able to do so with the strength of three people?

The evolved ant, although it looks like it is only magnified many times on the surface, and there are no other special changes, but the internal structure of its body has quietly changed, and the nerve reaction speed has increased many times, although the body only has the power of three people, but the nerve reaction speed is not weaker than that of level 8 monsters, so it can avoid the shooting of some bullets. This animal, which was almost the most humble and weakest animal in the world, now far surpasses those dogs, rats and other animals.

And eyesight, hearing, is its Achilles' heel!

However, in most cases, ants have dispensable hearing and vision, as long as they can see enemies within their attack range, which is basically sufficient.

Therefore, ants will become one of the most powerful monster groups in the later period.

The zombie fly only has the strength of five people, hearing, eyesight, and defense, but it is different from ants, and its advantage is the speed of nerve reactions.

The nerve response speed of flies is many times that of humans, the reaction speed of the eyes is 60 times that of humans, and the fluorescent lamp flashes 60 times per second, which humans cannot detect at all, but flies can clearly see it, and the hearing of flies is more agile in responding to sound sources.

Under the transformation of the virus, the body structure of flies has changed a lot, some of their abilities have been optimized, and some of them have directly degenerated, just like ants, today's ant monsters, any species, whether they are evolutionary or zombie-like dark ants, have no wings, as if they have been deprived of the ability to fly by God.

For example, termites originally had a pair of wings on their backs, but as they evolved, they gradually degenerated into two hard armor shields, which were extremely strong in defense.

And many of the structures of the fly have also been changed, although the strength and speed are only the strength of five people, but in terms of reaction speed, eyesight, and hearing, it is extremely powerful, increasing by 100 times, reaching the reaction speed of a level 50 human!

Ye Chen couldn't help but think in his heart that if the genes of flies and ants were fused, he didn't know how powerful they would be, and the two made up for each other's shortcomings.

"Poof!"

In the sky, corpses rained down, blood splattered.

The mosquito monster and the dark fly are all fighting together, forming a chaotic situation, completely indistinguishable from each other, in this narrow space, and it is a group battle, the fly's reaction speed advantage is not brought into play, it is pierced through the body, and is sucked into jerky.

In the world, there are only mosquito monsters that can absorb any blood without any scruples!

After the evolution, the structure of the mosquito monster has been strengthened and changed, even if the blood of these dark flies contains a large number of viruses, it can be absorbed, digested, and then discharged.

And other creatures don't dare to be so rampant, unless their own physique is too much stronger than the other party, they will not be afraid of being infected by the virus contained in the other party's blood.

"Squeak ......"

The two monsters were entangled together, fighting wildly, and the corpses kept falling, and it didn't take long for the corpses to become fewer and fewer, and the area above them became larger and larger.

About ten minutes later......

Poof!

The last mosquito monster was torn open by a few flies, and the blood rushed and fell miserably, and tens of thousands of mosquito monsters were slaughtered like this! And the 100,000 or so dark flies, there were only about 10,000 left, and they paid a heavy price, but these dark flies didn't care about this, and almost instinctively felt excited, pounced, and devoured the corpses of those mosquitoes.

The people hiding under the building were almost suffocating, holding their breath one by one, not daring to move.

After four or five hours......

The group of dark flies had a full meal and were about to rest, when suddenly a strange sound sounded in the distance, and these dark flies turned their heads to look, and suddenly they flew up, dragging the remaining mosquito corpses and flying away into the street.

Seeing this scene, Ye Chen frowned slightly, for a dark fly, it was habitable anywhere, why would he go to great lengths to move the corpse and move it into the distance?

Could it be...... There are dark fly kings in the distance, summoning them?

"Finally gone." The rest of the people stood up and breathed a sigh of relief.

"Let's go, it's getting dark." Mu Baifeng urged, took the lead and walked out of the building, and the rest of the people rubbed their squatting legs that were a little numb, and followed closely.

Ye Chen glanced at the wolf-like corpses on the ground outside, there was a hint of indifference in his eyes, in every corner of the world, something like this happened, humans are not the target of attack by so monsters, these monsters will also attack each other.

Especially in the early days, in the ocean, there were countless monsters dying, and they were simply corpses all over the field, floating corpses like mountains.

Next, everyone cautiously touched the base city together, encountered some small dangers along the way, encountered a single zombie, and were all shot, and finally successfully returned to the base city.

When Ye Chen and the others entered the city gate, the soldiers who inspected them just glanced at their clothes, and then did not stop them, and directly let them go.

"Damn, you have to base the meat when you enter the city, what bullshit rules!" Suddenly, at a procurator's office next to him, a stout man looked at the soldier angrily, obviously without the base flesh on his body, and looked a little angry.

The soldier said indifferently: "If you don't have Jihua meat, you can join the army, and according to your personal qualifications and potential, you can arrange to go to the right department, or if you are at worst, you can also enter the production department to help grow crops!" ”

The thick man said angrily: "Fart! Are you still a base city? When is it time for us to come over, and if we don't give food to eat, we still have to do coolies? What a garbage base city, Lao Tzu used to love the country in vain! ”

"Another stupid hat." Mu Baifeng glanced at it and sneered.

"Although there are more rules in the base city and less favors, in this case, it is very good to be able to give you a support." Another man sneered: "Does this person still think that the grain in the base city came for nothing?" Such a large base city has to operate, if you feed some waste in vain, it will collapse in a few days! ”

"What patriotism is this person talking about, what age is it, what an idiot!"

"If you want to adapt yourself to the world, don't you let the whole world obey you, this person doesn't even move such a simple truth, and thinks it's the previous era of peace? Paying attention to morality and ethics is the most important thing now as long as you can get strength and survive. ”

"Last time I saw a big general, on the street, but who dares to say him? The power of the people is there, although the general used to be just a cook in a hotel, but now, he has become a big man who controls 5,000 people! ”

A group of people whispered, looking at the strong man mockingly.

Ye Chen looked casually, only to see that the soldier pulled out his pistol and said coldly: "No matter how unreasonable it is, don't blame me for the military law!" ”

The stout man's face shook and changed color slightly, and finally under the persuasion of a few people who seemed to be acquaintances next to him, he found an opportunity to step down, hummed and chirped a few times, and finally chose to take refuge.
