Du Fei did not kill this colonel, the reason is very simple, this colonel is an officer of the 51st Military Region, and the military headquarters of the 51st Army is in Guangshi, so he can not care about offending the army, but he has to take care of his parents who are still in Guangshi.

And before the rebirth, the reputation of the 51st Military Region was better than that of other military regions, although it was fifty steps and a hundred steps, but at least it was not that bad. So if you want to choose to help a military district, give preference to the 51 military district.

However, these are not issues that need to be considered now, and now Du Fei is thinking about finding a place to spend the night.

The night of the end times is very dangerous, if one is not careful, it is possible to fall into the corpse group, if the corpse group is not strong, there is a creeper squad, and if it is not strong, there is also a mutant rat group. Even if the Transformers encounter the mutant rats, they have to peel off a layer of iron, not to mention people, and they will directly gnaw on the scum and scum.

At the beginning of the end times, mutated creatures will not immediately start to wreak havoc, after all, they still have the habit of being animals. Mutant rats, for example, do not prioritize humans as their prey unless they are hungry and crazy.

Mutant rats are omnivorous animals, they will first sweep up all kinds of edible things, and then start to eat the carrion of zombies, and then start to attack smaller animals, unmutated rats are excellent targets, and when ordinary animals are also eaten up, they will point the finger at humans.

Of course, zombies also prey on mice, whether the rat mutates or not. Of course, ordinary zombies basically can't catch mutant rats, but crawlers can, and they only need to stick out their tongues to roll the mutant rats back and swallow them.

Not to mention, there are mutant cats and dogs that specialize in preying on mutant rats, but the number of cats and dogs in the city is not large, and there are even fewer mutated.

Once the initial chaos in the food chain stabilized, famine began in the sewer world, and mutant rats would come out in patches at night, attacking any living creature in their path, as long as it was organic, they would swallow it.

Including gasoline, of course, the mutant rats in the beginning were not smart enough to bite the gas tank of a car, but there was always the first mouse to eat an apple, and when it did, the car fuel tank of the whole world would be gnawed to pieces.

The arrival of famine has caused more small animals to run wild, and cockroaches are one of the most terrifying of them. Although one or two mutant cockroaches are nothing, ordinary people can trample them to death with one foot, but when its unit rises to 10,000, 100,000, million, nothing can stop it except burning the city.

In fact, for animals, there is very little food in the city, so these snakes, insects, rats and ants will return to the forest in large numbers. This is a huge challenge to the forest's otherwise stable food chain.

Of course, plants are not good at stubble, and when they mutate, photosynthesis is no longer their only pursuit. Occasional meat is a good choice for some plants with a more arrogant personality.

However, it turns out that immobile plants do have a hard time adapting to a bloody predatory life. As a result of natural selection, plants with more green, more drought-tolerant and highly adaptable to soil conditions were the winners.

These super plants, which "can't be burned by wildfires and grow without the spring breeze", began to occupy the surface of the earth, and then spread to the bottom of the sea, starting a tug-of-war with the plants that grow in the sea.

The sea can't stop the green leaves, and the desert is not an obstacle. According to incomplete statistics, the progress of natural greening in the last three years has achieved something that human beings will never be able to do. Not only did it completely stop desertification, but it also turned the Sahara Desert into a savannah, and the Mara Gobi into a grass and mud rain.

The proliferation of plants has directly led to the promiscuity of herbivores, and cats that eat grass and snakes that gnaw on tree roots can be seen everywhere.

The proliferation of herbivores immediately solved the problem of famine among carnivores.

Coupled with the fact that marine organisms have mutated and developed ashore, it will eventually lead to complete chaos in the earth's ecosphere, and natural selection for survival of the fittest is the main theme of this "ecological war". Genetic mutation and optimization can reach heights that cannot be achieved in centuries or even millennia.

Mankind?

Being good at things is the greatest virtue of human beings, but it is also the greatest shackle that hinders human evolution, and in this "ecological war", human beings are on the verge of defeat from the very beginning.

This shackle of human beings can never be shaken off, because people with guns will never drop their guns to fight zombies.

After Du Fei was reborn, his eyes were no longer just on the minimum goal of "how to live". Therefore, he needs to look at the overall situation, defeating a zombie can only keep him alive, and grasping the victory of an "ecological war" can make the track of history biased towards his goal.

If humanity cannot be made the winner of this war, then "Pandora" will also lose the crown of victory.

In fact, the target of "Pandora" is the earth, not humans. In her eyes, human beings are just a group of prickly nails.

In a sense, the last days are only the last days of mankind, but they are the rebirth of the earth. The difference is that the ruler has changed from a human to a "Pandora". Only, did humans really rule the earth once?

Thinking of this, Du Fei had to smile helplessly.

Seeing that the sun was about to set, Du Fei needed to find a place to sleep. The first two hours of complete darkness are a good time to rest, and at night, it is not good to close your eyes, because then you will most likely never be able to open them again.

After the darkness before dawn dissipates, you can also make up for a sleep, and it can be regarded as a "nap". Fortunately, the awakened person has a good physique, and he can ensure that he does not die of sleepiness by sleeping for two hours a day.

Du Fei was looking for an open high place to rest, and suddenly heard several extremely subtle cries.

Curiosity, Du Fei searched for the sound, and saw an extended Lincoln parked not far away, as if the cry came from inside.

For some unknown reason, the front of the Lincoln car had sunk into a wall. The wheelhouse door was open, and there were some black-dried bloodstains, but there was no one, and there were no zombies.

Du Fei went over to inspect it, the front half of the carriage was empty, but the back half was sealed, and there was a blood stain flowing into the second half of the carriage along the internal door. This bloodstain is new, and it is estimated that someone has become a cup in this car in the past two days.

The crying came from the back half of the closed carriage, and the sound of someone talking could be faintly heard.

Du Fei used his source ability to melt the lock on the door, and then opened the built-in door.

Then I saw a large iron cage inside, in which were twin little girls in princess dresses, and the cage was full of snack wrappers and drink bottles.

The trail of blood that flowed in was gone at the edge of the cage. It's not that there is little blood and can't flow, but when you get there, you will be licked and eaten.

When Du Fei saw these two demon kings, the fear hidden in his heart in his previous life broke out of his shell, and it was as if a nuclear bomb had exploded in his head. He exhaled "Dark Twins" in horror, and instinctively turned around and ran away.

As soon as he escaped a few dozen meters, a muffled sound of "bang" sounded behind him. In the deep-seated fear of his previous life, Du Fei actually ran out of level 4 speed with level 3 light skills.
