The end of the world is approaching, I'm handing myself over to the country.

next second.

The previously barren open space behind the general store suddenly began to shake.

There was no lengthy construction process, nor any noisy machinery.

Space seemed to be twisted and reassembled by an invisible hand.

A few seconds later.

A building with a wasteland industrial style rose from the ground.

The gray metal exterior, the towering chimney, and that heavy blast-proof door.

The Pharmaceutical Factory (Level 1) is now complete.

[Production capacity: 1000 vials/hour (Primary Life Potion/Modifiable).]

Upgrade requirement: 50000 in revenue.

[Unlocked Building: Laboratory.]

Lin Mo looked at the newly appeared buildings and made some plans in his mind.

One thousand per hour.

This production capacity is sufficient to supply the current consumption of 1,000 players, and there is even a surplus.

No more tedious hand-blending of medicines one by one!

By handing over tedious and repetitive labor to the factory, he can free up his hands to do other things.

For example, developing real gene-editing agents.

That's what allows humanity to break through its limits and truly gain a foothold in this apocalyptic world.

The end-of-month assessment will feature boss-level monsters, so it's still best to take the elite route.

Otherwise, there's absolutely no chance.

Primary gene therapy is the best breakthrough point.

But Lin Mo immediately realized a new problem.

raw materials.

Even if you have a factory and production capacity, it's all for nothing if you can't keep up with the demand for raw materials.

Crafting gene potions and basic life potions requires a large amount of monster blood.

Especially the blood of servant-level monsters.

If you buy it from the system store, it will not only consume your sales revenue, but it will also be ridiculously expensive.

For Lin Mo, there are two types of currency.

One is revenue, and the other is the source crystal.

Sales revenue can upgrade the general store's level, upgrade buildings and factories, or be used for purchases in the system store.

The main function of Source Crystals is to teleport items back to the past. They can also issue various event tasks to 'players' and give them rewards.

If we're talking about what's important, then revenue is the most important.

Unless absolutely necessary, it is best not to misuse turnover.

But in the end, this matter is actually quite easy to resolve.

Lin Mo turned around and looked outside the grocery store.

Aren't those "players" outside who are fighting desperately for a few source crystals the best collectors?

There's plenty of available labor; might as well use it.

The happiness of capitalists is often so simple and unpretentious.

He quickly edited a server-wide announcement in the system backend.

......

In the wasteland, on the top floor of an abandoned building.

Chen Feng was using binoculars to observe the movement of the horde of corpses in the distance.

Lei Yue was wiping the heavy machine gun he had just acquired, his eyes full of mockery: "Those idiots are really fierce. They dared to go into the Death Mine without any equipment."

Should we praise their courage, or their fearlessness?

Zhou Jian felt terrible just thinking about those insects.

"Even top-tier weapons couldn't leave any marks on those insects. If those insects weren't afraid of light and couldn't get out, we would all have died inside."

Lei Yue nodded in agreement: "Those bugs are really freakish. My gun barrel was red-hot, and I fired tens of thousands of bullets, but when I checked, there were zero casualties. I really don't know how to kill those damn bugs."

Just then.

A golden exclamation mark simultaneously popped up in front of everyone's eyes.

[Server-wide Announcement: Limited-Time Recycling Event Begins!]

[Description: The general store urgently needs a large quantity of Servant-level monster blood as raw material.]

[Rules: During the event, players can sell the monster blood they collect to the general store.] (Remote recycling is supported.)

[Reward: In addition to the regular Source Crystal rewards, the top three players with the highest recycling volume will receive an extra "Basic Gene Potion".]

[Limited time offer: 24 hours.]

Chen Feng abruptly put down the binoculars.

"Primary gene serum?"

These words seemed to possess a magical power, instantly capturing everyone's attention.

Zhou Jian stopped wielding his dagger: "Wow, is this for real? Monster blood is useless anyway; it just spills everywhere after killing a monster. Now it can actually be exchanged for money?"

In the past, when they killed monsters, they only took the useful materials.

Blood is a foul-smelling substance that cannot be recycled.

"The key point is not the source crystal."

Chen Feng opened the details page of the announcement and pointed to the last line: "The key point is this gene serum."

"What's the use of this thing?" Lei Yue leaned closer. "Does it increase combat power?"

"It's most likely an item that permanently boosts attributes."

Qin Feng calmly analyzed, "According to the usual game tropes, the word 'gene' usually signifies evolution and transformation. This may be the key to breaking through our current combat power bottleneck."

Even though today's players have guns and cannons, their physical abilities are still at the level of ordinary people.

Getting scratched by a zombie will cause infection, and getting bitten by an insect will break your leg.

If it could strengthen the body...

The combat power will definitely be a qualitative leap.

"But there are only three."

Zhao Yunfeng frowned. "How many people are in the game now? Almost a thousand, right?"

A thousand people.

Fight for three doses of medicine.

This ratio is even more brutal than that of taking the civil service exam.

"Even if we have the initial advantage, we can't possibly get everything."

Chen Feng's mind raced, and he instantly devised a strategy: "We are a team, but this time the reward is calculated on an individual basis. If we split up, we will have no advantage."

"Those guys may not be as well-equipped as us, but they're no pushovers."

"The safest approach is to concentrate resources and focus on one thing at a time."

Chen Feng looked at everyone and said, "The ten of us will hunt monsters with all our might, collect their blood, and then combine all the blood into one person to complete the mission."

Zhou Jian whistled: "A guaranteed admission?"

"Yes, it's a guaranteed admission."

Chen Feng nodded: "We can only compete for one of them."

"Don't bite off more than you can chew. Trying to get three is a pipe dream. Winning one is a victory in itself."

This is not just a competition for game items.

It's also a contest of skill between beta testers.

Whoever obtains the first gene serum will gain a half-step advantage in this cruel world.

One step at a time, one step at a time.

"Then who should it be given to?"

All eyes turned to Chen Feng.

"For Lao Zhou."

Chen Feng made a decision: "His fighting style is more close-range, so he needs to improve his physical fitness the most."

Zhou Jian was stunned for a moment, then rushed excitedly towards Chen Feng, grabbed him, and lifted him up.

Happiness shouldn't come too suddenly: "Captain, I love you!"

Don't get too excited yet.

Chen Feng looked out the window, where he could faintly hear the sounds of intense fighting in the distance.

That's when the other players started to make their move.

"From this moment on, not a single drop of blood can be wasted."

Chen Feng raised his rock-splitting sword: "This isn't fighting monsters, this is robbing."

"Set off!"
