Fang Heng raised his head and asked, “Do you know where they will gather?”

“Hmm, it should be in the Songxi Mountain area. The Federation has a large-scale shelter there, and all the materials are temporarily gathered there. The president and I have studied it before, and the chances of forcefully attacking there are very small.”

“Hmm.” Fang Heng continued to ask, “How are the preparations for the materials to make the anti-virus vaccine coming along?”

“We have reached an agreement with the Federation. We have used 10,000 doses of anti-mutant worm injections to exchange for a portion of the funds and a large number of medicinal ingredients. It is expected that the medicinal ingredients will reach our gaming union’s shelter before sunset tonight. When that time comes, we will secretly transport them through the teleportation passage to the research institute.”

Zhong Lei made a rough estimate. “Together with the materials that we purchased ourselves, it should be enough to make the second batch of highly concentrated anti-virus vaccine.”

“Alright.”

Fang Heng clenched his fist and patted Zhong Lei’s shoulder. “Go and tell the Federation that we’ve leveled up the anti-mutant worm injection again. It’s even more effective than the previous one. After the injection, we can remain immune to the attacks of the mutant worm bodies for a period of time. Ask them if they still want it. If they want it, they’ll have to pay more.”

“Ah? This?”

Zhong Lei was stunned.

What was going on?

They clearly knew that the Federation’s people had already rushed over. Why would they still think of a way to send bullets to the Federation?

Was Fang Heng crazy? Was he planning to take a large sum of money from the Federation and leave?

“Think of a way to get all the medicinal ingredients and materials from the Federation’s reserve. If they don’t have the medicinal ingredients, let them use the funds to pay for it. Also, before the sun sets tonight, the materials must be delivered to the Federation!”

Zhong Lei swallowed his saliva.

Medicinal ingredients?

Suddenly, Zhong Lei suddenly understood the purpose of Fang Heng’s move.

“Fang Heng… You mean to say…”

“Mm, you’re right.”

Smash a pot to pieces just because it’s cracked.

Mass-produce a highly concentrated anti-virus vaccine and then throw the vaccine to the Eastern region!

Zhong Lei felt a chill down his spine.

What the heck!

He did not expect Fang Heng to be so tough!

Previously, in the scorched area, only about half of the high-concentration anti-virus vaccine had been produced in the Western region.

Up until now, the entire Western region was still in chaos. It was thrown into chaos by the sudden outbreak of the giant-sized zombie tide.

In theory, if they had the Federation’s medicinal ingredients, they could produce a high-concentration anti-virus vaccine that was ten times stronger.

If the Federation encountered a zombie horde halfway through their attempt to attack the Scavenger Army…

Zhong Lei’s breathing became heavy.

Even the Federation would definitely be wiped out there!

Not to mention the Federation, even the entire Eastern region would be dragged into the zombie horde by the vaccine!

Even the Scavenger Army could not avoid being affected by the zombie horde…

“Hurry up. We have limited time. Quickly tell Tian Zhen to think of a way to do it. We don’t have much time.”

Zhong Lei took a deep breath.

“Okay!”

Watching Zhong Lei rush back to report, Fang Heng also stretched.

It was time to start working again.

Apart from making a large number of anti-mutant worm body injections to deliver to the Federation, he also needed to make a large number of highly concentrated anti-virus vaccines.

Fang Heng had already predicted that tonight would be a sleepless night.

Fine, if this went on, he would definitely stay up all night and die!

After thinking about it, Fang Heng threw down a mattress and quickly went offline to catch up on his sleep.

…

He went online again, and the first thing Fang Heng did was to look for Ding Min.

“Wait a moment.”

Ding Min was busy working in front of the experiment table.

After a moment, she put down the temporary potion that she had just finished, turned her head, and looked at Fang Heng.

“We’ve already done more than half of the research. The sample data we’ve collected so far is enough for us to improve and develop the first stage of the vaccine.”

“Improve and develop? You mean the antibody virus vaccine?”

Fang Heng was stunned.

“Yes. After improving, the probability of zombies mutating will reduce slightly from the vaccine’s effectiveness, and the speed of its spread will also increase slightly.” Ding Min said. She yawned and explained, “However, the improvement and development will still require some time.”

A row of game hints appeared in Fang Heng’s retina.

[Hint: The research team of the Scavenger Army has completed the analysis of Tier 1 mutated zombie live samples * 9. Main storyline — Data collection mission completion rate increased to: 84.124%.]

[Hint: The research team of the Scavenger Army has completed the analysis of Tier 2 mutated zombie live samples * 12. Main storyline — Data collection mission completion rate increased to: 102.288%.]

[Hint: Your current data collection has reached 100%. You can now proceed to level up the vaccine body.]

Fang Heng skimmed through the game hint and suddenly had an epiphany.

Therefore, the high concentration of the antibody virus vaccine could be leveled up.

In theory, as the virus continued to spread and the sample information collected increased, the vaccine would also continue to level up.

By then, the mutation rate of the zombies would improve, and the pressure on them would be greatly reduced.

Fang Heng opened the game hint and checked it again.

[Hint: District 7’s vaccine diffusion rate: 0.0005%, Western region’s vaccine diffusion rate: 0.0261%, player’s zone vaccine diffusion rate: 0%, zone mutation rate: 0%, zone purification rate: 0%.]

Should he increase the vaccine body diffusion rate to 100%? There was also the choice of zone purification rate.

Once the zone purification rate reached 100%, would it mean that the entire zone would be purified?

In the morning, the scorched area’s purification rate of 24 was already on the verge of collapse.

Wait…

If he could borrow the Federation’s strength, would he be able to increase the purification rate to 100%?

Fang Heng’s thoughts started to come alive again.

“Fang Heng.”

“Eh?”

Ding Min asked, “When do we start the research and development work?”

“No, there’s no need to be in such a hurry.” Fang Heng smiled gently and said, “It’s too late. It’s not good to stay up all night. You should go and rest first. You’ve worked hard these past two days. I’ll give you a day off, and you can continue to rest tomorrow. Leave the rest to me.”

New research and development? Improve the mutation rate of zombies?

Fang Heng couldn’t wait for the zombies’ mutation rate to be as high as possible!

He wasn’t in a hurry to develop an improved potion. He would talk about it in the future!

“Eh? Why are you so nice all of a sudden?”

Hearing that she didn’t need to stay up all night, Ding Min looked at Fang Heng in surprise.

Ever since Fang Heng became the commander of the Scavenger Army, Ding Min had classified Fang Heng as a fighter.

She was still not used to seeing Fang Heng give her a break.

“Hey, don’t look at me like that. I’m not a bad person…”

After confirming that Fang Heng was not joking, Ding Min’s mood improved a little. She rubbed her sore shoulder.

“Okay, then I’ll go rest.”

[Hint: Your favorability rating with Ding Min has slightly increased. Ding Min’s loyalty to the Scavenger Army has increased to 96].
