Large-scale eradication of zombies and large-scale collection of resources were launched under the announcement of Shen Yan and other high-level officials at the Fengcheng base. Whether it was a wolf warrior or a house wolf under Shen Yan's command, the true nature of the locusts when he returned from Xinyang all the way was vividly played this time, and it was even better than before, except for those buildings in the entire Fengcheng, it was inconvenient to take away, and almost all that could be taken away was looted!

In the blink of an eye, three months had passed since such a large-scale action, and it had been four months for Shen Yan to return to Ning Province.

It stands to reason that the weather in the north has begun to turn cold in October, and January and February are the coldest seasons. At the beginning, in order to survive the winter, Shen Yan even specially told Zhan Tiancheng, and took the trouble to lead the troops to several coal mines hundreds of kilometers away to pull coal. But the strange thing is that this year's winter temperature dropped very early, but it has not been too cold, in previous years it was minus ten degrees, but now it is only minus a few degrees!

As the saying goes, there must be a demon when things go wrong, in order to prevent Shen Yan from launching a large-scale clean-up of zombies and a large-scale collection of resources, he also urged the construction personnel of the base to speed up the pace of construction. After all, even if you don't take precautions, just the mutant beasts that have appeared one after another must let Shen Yan speed up the pace of all this! That mutant beast is no better than zombies, and the number of zombies will be less due to population restrictions, but those mutant beasts are not like this, and there are probably more rats than zombies alone!

Fortunately, Mira also said that the virus modifies animals although they can't change them into the same as zombies. They are just transformed by the virus, and their original innate abilities have been improved, but this improvement also has a certain price, that is, the success rate!

There is only one way for humans to be infected with the virus, and that is to become zombies. For normal people, becoming a zombie represents death, and in a sense, zombies are also a kind of life! But animals are different, they have two ways to choose, adapt to the virus to get modified and strengthened talents, and if they don't adapt, they will die directly, and this mortality rate is still very high!

Viruses can stimulate the original predatory caste of animals, and even those herbivores will become omnivorous under the modification of the virus. But they are still animals themselves, they can still be tamed, and their meat can also be used as food.

Although animals will eventually die in large numbers due to the modification of the virus, Shen Yan has always understood one truth, that is, the reproductive ability of animals. In the past, humans occupied and controlled the earth, and many animals were on the verge of extinction, but after the catastrophe, humans were too busy to take care of themselves, and no one paid attention to what the mutant beasts would develop, who knows? Especially under the modification of the virus, will their reproductive ability become higher while their strength increases?

In short, everything forced Shen Yan to speed up the construction of the base and the reserve of various materials! Even with the experts and technicians of the base, who are familiar with the various equipment, instruments and other systems in the warehouse ruins, the ecosystem has begun to operate, and even through research and Mira's guidance, all the twenty reading spaces inside the warehouse have been transformed into ecological parks!

The great purge of zombies in Fengcheng allowed Shen Yan to rescue a large number of survivors from them, making the population of the entire base more than 350,000. The increase in population means that the base will have more labor, but it also means that there will be a huge pressure on materials!

Just when the wolf warrior under Shen Yan's command attacked from all sides and gradually controlled the entire three districts of Fengcheng, the time had entered March of the second year, and at this time, the mutant beasts he had been waiting for for a long time finally began to appear in the city area!

"The situation is not optimistic!" In the conference room of the headquarters of the first base of Fengcheng, Lei Zheng said to everyone present: "Through the reports fed back by the troops, the frequency of mutant beasts is getting higher and higher, and there were only one or two before, and the number was no more than ten at most. But recently, dozens or hundreds of small groups of mutant beasts have appeared, and some of the mutant beasts have begun to merge and slowly move towards our base! ”

"There should be no problem! The walls of the base have been built, and a moat has been dug outside the city walls, as well as bunkers on the city walls, and even if they come, they should not be able to attack them. Zhan Tiancheng's eyeballs were bloodshot, and he flicked the cigarette ash and said.

Since the discovery of the second base and the launch of a big move, the person in charge of Zhan Tiancheng's base has basically not slept a single night, if it weren't for Shen Yan's blood-strengthened body to support him, I'm afraid he would have been tired and lying down! Fortunately, with the increase in the number of people and the influx of a large number of materials, all sections have been gradually completed, especially the moat dug out of the city wall that is 100 meters wide and 50 meters deep, which makes him very confident in defending against the attacks of mutant beasts.

"It's not that simple, now that our moat is not watered, that depth can't affect the mutant beast at all. And don't forget, except for land animals, they are still heavenly. It was Guan Feng who answered, and when he said this, he couldn't help but scold: "Made, what is this broken virus, a sparrow is about to catch up with the eagle after mutating, if this suddenly comes to a flock, then it will be okay?" ”

"Huh!" Shen Yan said with a smile: "Haven't the technicians of our base already created machine guns and artillery, even if the number of those mutant beasts is a little more, with our fifty-meter-high city wall, they can really turn against the sky?" ”

Facing Shen Yan's relaxed face, without waiting for Guan Feng's interface, Zhan Tiancheng had already smiled bitterly: "Little wolf, you have really become a hands-off shopkeeper now, only taking the wolf to clear the mutant beasts in Helan Mountain, and don't care about anything else, do you really want to exhaust us?" ”

Shen Yan smiled embarrassedly when he heard this, and said, "There's no way, the mutant beasts over there in Helan Mountain appeared early, and they must be constantly eliminated for the construction of the second base!" Fortunately, now that the periphery of the second base has been built, even if there is really a large group of mutant beasts, there is no fear! ”

Today's base command system has been thoroughly improved! Just like Zhan Tiancheng said, Shen Yan basically fought except for fighting, and he completely became a shopkeeper. In terms of administrative management, Zhan Tiancheng is now the number one leader of the base, and the army management is directly handed over to Lei Zheng, as for Guan Feng, he is the commander-in-chief of the elite wolf warrior group!

In terms of administration, Zhan Tiancheng is a veteran, and now the construction and management of the entire base is all up to him, except for the tiredness, he is really like a soil emperor! Lei Zheng was the political commissar of the Ning Provincial Armed Police Corps, and he was also handy in the management of the troops, since the other party became a member of the wolf pack, Shen Yan directly waved his hand, and all the troops were handed over to the other party. Now there are ten regiments under the jurisdiction of the entire base, each with 2,000 people, and a total of 20,000 are all under his command, and Shen Yan, Guan Feng and others do not interfere at all in this regard!

And Guan Feng controls 2,000 people, if the Wolf Warrior Legion under Lei Zheng is the basic force of the entire base's armed forces, then the 2,000 elite Wolf Warriors under Guan Feng are a sharp knife of the entire base, and their existence is only for fighting, only to continuously improve their strength!

The selection of elite wolf warriors is completely carried out from the wolf warrior legion, and the first condition must be that the strengthening level reaches level three, and then it has to go through the layers of assessment set by Guan Feng, and finally the warrior wolves who pass the assessment also need to be eliminated internally, and finally they can get the identity of the elite wolf warrior and join the elite wolf warrior group. Even so, they are only reserve personnel, and they will only be replenished after the elite wolf warrior group is depleted. In other words, the number of elite wolf warriors is up to two thousand, and it will not break through!

In the past few months, the survivors of the He County base and the survivors rescued by Fengcheng have all completed the injection of Shen Yan's blood, and so far, there are still all Bacheng benevolent members who have become members of the wolf pack, and the remaining two percent have not been completely transformed because of the lack of injection time! During this period, of course, there are also those who cannot complete the transformation after a period of time, just like Luo Jian in the Hexian base earlier. Fortunately, these people were only a minority, and they were quickly cleaned up.

The second base on the side of Helan Mountain, where Shen Yan placed all the scientific research personnel and technicians, in addition to 100,000 ordinary people and two wolf warrior regiments, the former of which was responsible for the construction of the second base, and the latter was responsible for defense.

At the beginning, in response to the construction of the second base, many people chose to build a 500-meter space in layers, so as to increase the population capacity of the second base. After thinking about it for a few days, Shen Yan still decided not to stratify.

What's wrong with five hundred meters high, it's a big deal that the internal building is a little taller, with the knowledge of warehouse civilization, the entire three or four hundred meters high all-metal building will not be in the way even if there is an earthquake, and it can accommodate a lot of people! According to Shen Yan's thoughts, in the end, the development of human beings still has to be on the ground, and it is safe to huddle all underground, but in a safe state, it will always wear down people's will. How did sub-health come about before the disaster? Isn't it because people are too casual?

In any case, with the increase in population and the influx of resources, the construction of the two bases in Fengcheng has been roughly completed in four months. But now, the appearance of mutant beasts will curb the speed of construction.

"Okay, I think we continue to pay close attention to the construction work, especially the several small factories in the second base, we must increase our efforts, as long as we can be self-sufficient in the corresponding materials, with our current defense, we will not be afraid even if they come." Shen Yan finally decided: "But the troops have to take it away, and it is not good for us to fight the mutant beasts outside!" ”

"Well, I was ...... before," Lei was nodding, but before he could finish his sentence, there was a knock on the door of the conference room.

A soldier walked in quickly, and a document was handed to Lei Zheng. After Lei Zheng quickly read the documents, he looked up at everyone and said solemnly: "The gathering speed of the mutant beast herd has accelerated, and more than a dozen mutant beast groups with a number of more than five thousand have gathered towards the base. At the same time, there are at least 100,000 mutant rat swarms moving towards the base! ”
