The harvest this time was really considerable.

Now that we have the crystal core, all we need to do next is upgrade it to level 45.

Chen Tinghan put the things away and looked towards the factory area.

He said to the three of them, "Come on, follow me over and take a look. So many level 2 zombies just appeared. This place must be something special."

Yang Fei, Pan Datong and He Ping nodded, and they also felt that something was unusual over there.

The group walked straight over and headed towards the factory.

There is a fence in front, and looking inside, you can see many tall factory buildings.

There are material areas, electrolyte areas, high potassium production areas, electrolyte area 2, canteen, brine tanks, boiler rooms, and a reserved area.

There were many corpses on the road, all of which were eaten beyond recognition by the zombies.

At this moment, some noises were heard from inside the machine repair shop, and then an iron door outside was pushed open.

Several disheveled people came out from inside.

These people are the missing members.

There are four of them in total, all of whom are official members, including Ouyang Ke, Song Kaiyun and two others.

When the four people saw Chen Tinghan and the three others, they immediately became happy.

Song Kaiyun ran up excitedly and said, "Archbishop, I knew you would come to save us."

Yang Fei quickly asked, "Have you been bitten by zombies?"

He was afraid that these four people would be bitten by zombies.

Ouyang Ke said: "I was not bitten by a zombie. Others don't know. You can check it out."

Yang Fei said, "He Ping, go and take a look."

He Ping nodded and went straight up to check.

After a while, he finished the inspection.

None of the four people were scratched or bitten by the zombies.

Yang Fei said: "I'm glad you're okay. The zombies outside have been cleared out. You are safe now."

Then he looked at Ouyang Ke and asked, "Are there any other survivors here?"

Ouyang Ke said: "There shouldn't be any other survivors."

"We all fled separately at that time."

Yang Fei looked at Chen Tinghan and asked, "Archbishop, do you want to look for him?"

Chen Tinghan said, "Let's look for it again."

Everyone inside and outside the group shouted loudly.

More than ten minutes passed and not a single ghost was seen.

A group of people gathered at the factory gate.

Chen Tinghan looked at the charred zombies and suddenly asked, "There are so many mutated zombies here, what do you think?"

Ouyang Ke said, "This is a chemical factory. Could it be that some chemical raw materials can promote the evolution of these zombies, just like in some zombie games?"

Yang Fei shook his head, disagreeing. He said, "That's impossible. Ordinary chemical raw materials won't cause these zombies to mutate."

Chen Tinghan looked at him and asked, "Then how do you think so many level 2 zombies appeared?"

Yang Fei said solemnly: "I suspect there may be a more powerful virus strain here, the third generation, or even the second generation."

"The original alpha strain may no longer exist, but beta and gamma certainly still exist in nature."

Chen Tinghan remembered the first-level archival document he saw last time.

If this is true, perhaps we can obtain this strain and cultivate some advanced zombies.

He thought for a moment and said, "Yang Fei, contact the base and ask Wu Mengzhi to send a researcher over. I hope to find the third-generation virus here."

When Yang Fei heard this, he took out his satellite phone, made a call, and told them what had happened.

After hanging up the phone, he hesitated and said, "Archbishop, are you going to find these viruses and cultivate them yourself?"

Chen Tinghan nodded directly and said, "That's right, just say whatever you want to say."

Yang Fei said: "Archbishop, there are third-generation strains in the base, and there are more than one, more than 30 kinds."

Chen Tinghan was surprised and asked, "So many? Can these strains make zombies born from humans produce crystal nuclei?"

Yang Fei nodded and said, "It can be done, but it's not stable. The individual differences are too great."

"Some people do produce crystal nuclei, but some don't. The ratio might be as high as one in ten."

Chen Tinghan couldn't help but nod, then asked, "By the way, what level of crystal cores do they usually produce?"

Yang Fei said: "Usually it's a level one zombie crystal core."

"There are so many secondary cases here, there may be other reasons."

Chen Tinghan nodded slightly, as if thinking about something.

In the future, we don’t have to kill enemies directly. We can just capture them and inject them with the third-generation strain.

"Can those second-generation strains be extracted from the crystal nucleus?" Chen Tinghan suddenly asked again.

Yang Fei shook his head: "I'm not very clear about this. The Archbishop can ask those researchers when he returns."

Chen Tinghan nodded slightly: "Okay, let's go, we'll go back now."

A group of eight people drove two cars to Tushan Base.

More than an hour later.

It was getting dark.

The group defended the base.

Chen Tinghan went to the laboratory and asked about the second-generation virus.

This second-generation virus can also be found in the crystal nucleus, but it is very difficult to extract it.

The researcher said that it could be tried, but it would require a lot of crystal cores for experiments and research, and it would be best if they were high-grade crystal cores.

After hearing this, Chen Tinghan lost interest.

Walking out of the laboratory and standing in the darkness, he thought for a while and found Wu Mengzhi.

Then ask him to find a group of good-looking women and take them away from here to see if they are willing.

Afterwards, Chen Tinghan came to the small garden.

The room is dark.

Xu Yunxi and Fang Muyan fell asleep.

Xu Yunxi hasn't fallen asleep yet.

In the past, this was the beginning of nightlife.

Fang Muyan was asleep now, breathing evenly.

At this time, Xu Yunxi heard some noise outside.

That man is coming?

She thought about the last time.

That time was really ridiculous.

She quietly got up, put on her slippers and walked over.

Then, she felt a black shadow flash and the door opened.

Then someone appeared beside her and hugged her around the waist.

Xu Yunxi's heart skipped a beat.

Sure enough, it was that man coming over.

Chen Tinghan carried the woman to the bed.

Xu Yunxi struggled slightly, and a strange feeling emerged in her heart.

"I'm leaving. You and Mu Yan will leave with me tomorrow."
