The team traveled some distance from the base, the number of zombies continued unabated, and as many people completed the task of the crystal nucleus one after another, Yu Yanfeng ordered to prepare the journey back to the base.

However, in the end, it was just preparation, and there was no immediate action, and the rest of the people did not complete the task so ideally.

Yu Yanfeng left them enough time and opportunities, and each team they were divided into gave them a lot of opportunities to cooperate with each other, as for how to score the crystal nuclei they obtained, they also decided by themselves, and they only needed to pay a few crystal nuclei to maintain the team's expenses.

In such a situation, failure to complete the task, even if there are some extenuating circumstances, will inevitably be punished.

Those who did not complete the task were sent out to be the vanguard, which was nothing, but after a few people died due to improper cooperation, there were some discordant voices in the team.

These discordant voices have appeared before, but after Yu Yanfeng suppressed them with iron-blooded means, no one had the heart to mention them again.

This time, it seems that someone deliberately spread it, causing resentment in the hearts of others.

As soon as Yu Yanfeng ordered someone to investigate, there was another accident, and several people had symptoms of high fever mutation.

As soon as it was discovered that someone had this symptom, it was immediately controlled, and an investigation was carried out, and this investigation found that there were many cases of this situation.

There are no injuries on his body, and there are also people with abilities among them, Yu Yanfeng sensed the seriousness of the matter and went to investigate it himself.

This investigation found out the food and meat foam that appeared in the team.

The team will provide food, most of which are packaging items that can be stored, and of course, some naan and steamed buns made before leaving the base are all dried.

The meat foam that appeared in the team was purely boiled in water and then put some salt in it, although it didn't taste so good, because the meat foam also had a rancid taste, but they didn't eat meat for a long time, and they ate it very well.

The reason why these people dare to eat rancid meat foam is that the person who provided it is an acquaintance, and it is he who takes the lead in eating it and is seen by others, so that others will eat it together.

These people didn't expect that something would really happen.

Just when Yu Yanfeng interrogated them, there was already a person who had completely mutated into a zombie.

Unfortunately, it happened to be the one who provided the meat foam.

Yu Yanfeng personally gave him a shot, and then his eyes swept over the rest of the people and said in a deep voice.

"If you want to live, stick to it."

Dropping this sentence, Yu Yanfeng asked people to keep an eye on these detainees and walked outside.

There are also a lot of people outside, there are relatives and friends of these people, and of course there are some worries.

People are always afraid in an unknown situation, and when they are afraid, they can't stay, and at this moment people are panicked and anxious and shouting loudly there.

As soon as Yu Yanfeng appeared, the scene was quiet, and his momentum of not being angry and arrogant was not something that everyone could resist.

"What are you doing here? Is the task not heavy enough? ”

"Captain Yuan, how is my son? Will he become a zombie, Captain Yuan, I'm just such a son! ”

It was a middle-aged man in his fifties who spoke, not looking old, but his voice trembled and he said those words, covering his eyes and wiping away tears.

As soon as he spoke, the emotions of the others also mobilized.

"Admiral Yuan, this brother of mine has always been fine, he has never been caught by zombies, we have been on a mission together, how could he mutate?"

"Captain Yuan, how can so many people mutate, what the hell is going on, will we also become zombies?"
