Fang Heng and the other two arrived at the headquarters of the Dark Knights through the portal.

David and a group of elite dark knights were waiting for Fang Heng.

“Fang Heng.”

David went forward and gave Fang Heng a warm hug. His eyes were shining with irresistible excitement.

“Finally you’re here. I guarantee that our research findings will definitely surprise you!”

“I’m looking forward to it!”

“Come on, follow me.”

David led Qiu Yaokang and the other two to put on thick protective isolation suits. After sterilizing them, they arrived at the underground secret research room located in the headquarters.

The first generation meteorites were placed behind the tempered glass.

“With the help of Mr. Qiu Yaokang, we have been researching and developing the first generation meteorites. Overall, the current progress is gratifying. Through the analysis of the sample of the first generation meteorites, we have successfully developed a vaccine for the primogenitor virus.”

Fang Heng’s eyes widened, then he turned to look at Qiu Yaokang.

“Vaccine?” he thought.

“It developed so fast!?”

Mo Jiawei also looked at Qiu Yaokang in surprise.

“Develop a vaccine? Did it mean that they could successfully complete the main task of District 8?”

Qiu Yaokang looked indifferent.

Developing a vaccine was quite an ordinary thing to him.

“Thank you very much for your help, Mr. Qiu Yaokang. Let me introduce the situation of the vaccine.”

David suppressed the excitement in his heart, he continued to explain,”The vaccine can work against the primogenitor virus. Theoretically, all the zombie virus that we know of are mutated from the primogenitor virus. The vaccine that we developed can have a positive effect on the virus.”

“We have carried out clinical trials. The effect is significant. After the vaccine is injected, the human body can be completely immune to the infection of the zombie virus for a period of time.”

Qiu yaokang continued,”But now is not the time to celebrate. This is only theoretically possible. There are still great risks in the actual process.”

“Risks?”

“Yes.” David turned to look at Fang Heng.”Since the outbreak of the zombie crisis, there has been a problem that has been troubling all the research personel in the world.”

“I don’t know if you have realized it, but the number of zombies in the zombie team is still increasing.”

“Every day, countless corpses that have been dead for many years are resurrected from the ground. The resurrected zombies are indeed infected with the zombie virus, but their zombie transformation process is hard to explain with the zombie virus theory. After all, they have never been exposed to the zombie virus.”

Fang Heng glanced at Mo Jiawei, who also looked back at Fang Heng.

The players had discovered this bizarre situation a long time ago.

If not for the fact that a large number of zombies were resurrected from the ground every day, it would have been possible to kill all the zombies wandering around the world with the player’s strength.

However, the player would not think too much about such a situation.

They simply attributed this to a simple rule.

It was the game settings.

It was just like the Blood Moon.

For a long time, the game system would give a Hint of the Blood Moon’s arrival in advance.

Almost no player would think about how the Blood Moon came into being.

When it came to the NPCs, they felt that the Blood Moon and the zombie team were very strange.

Fang Heng was thinking about how to explain the problem to them when Qiu Yaokang said, “Some time ago, I conducted a new test and research on the zombie team that resurrected from the underground.”

“I found traces of the primogenitor virus in their bodies.”

Fang Heng stopped talking and asked in surprise,”Are you saying that the zombies that crawled out of the underground were infected with the primogenitor virus?”

“Yes, it’s very strange. How did the primogenitor virus infect the corpse buried deep underground?”

Qiu Yaokang said in a deep voice, “After several tests, I came to a conclusion that the ground under our feet was contaminated.”

Fang Heng frowned.

He felt that something was wrong.

After listening for a long time, Mo Jiawei couldn’t help but say, “But, Qiu, I still don’t understand. What does this have to do with us?” “Haven’t we already developed a vaccine?” “Since the vaccine is effective against the primogenitor virus, what risks are there?” “Why don’t we just inject the vaccine together?”

“That’s what I’m going to explain next.”

“Injecting the vaccine into the human body is only a cure for the symptoms, not the root cause. Only by finding a way to stop the zombies that emerged from the underground can we completely solve the crisis of the human race.”

“According to what I said before, the polluted land is the source of the rising of the dead that are buried deep underground.”

“We have to find a way to solve the root cause.”

“Ideally, the vaccine we have developed can directly destroy the virus. With sufficient doses of the vaccine, we can purify the polluted land, stop the zombie transformation of the dead, and restore peace to the world.”

Mo Jiawei clapped his hands, “Then what are we waiting for? Mass production! What materials do we need? We’ll go and help collect them now.”

“It’s not that simple. The primogenitor virus is very unstable, which is why it split into T virus, G virus, and other virus bodies. The vaccine we developed is still very unstable.”

“To be precise, the vaccine still has a huge safety risk. A large-scale spread of the vaccine may lead to further evolution of the virus body. In extreme cases, a large number of evolved mutated zombie will be resurrected from the contaminated land every day.”

Fang Heng finally understood.

After a long time, this vaccine was still a half-finished product with risks.

One after another, game Hints flashed past Fang Heng’s retina.

“Hint: player has completed the current phase of the mission with the Dark Knights — first-generation meteorite research”

“Hint: player’s behavior has changed the game process, and is in the process of correction…”

“Hint: correction completed. Player has received 20,000 District 8 main storyline contribution points.”

“Hint: player has received 12,000 Dark Knights contribution points. Player’s Dark Knights’honor level has been raised to LV: 23. Vice-commander.”

“Fang Heng, no matter what, we were able to develop the vaccine body largely because of your help all this time. On behalf of the Dark Knights, we thank you for your contribution to saving the world. The commander has personally appointed you as the vice-commander of the Dark Knights.”

As he spoke, David’s expression turned solemn. He saluted Fang Heng and said,”Commander Fang Heng!”

“Uh… well, thank you…”

Fang Heng’s expression was a little awkward.

He thought about how he had just destroyed the branch of the Dark Knights in District 7, and then became the vice-commander of the Dark Knights in District 8.

He was really confused.

“The Night Owl organization would not be so stupid as to kill the commander of the Dark Knights, right?” he thought.

“Fang Heng, we are now divided on what we should do next. Should we use the unstable vaccine immediately or wait a little longer? We should develop and observe it for a while more and analyze it for a while more to ensure the safety of the vaccine.”
