The male supporting character was actually myself.

Just as the little white cat was about to wave goodbye, it suddenly remembered something and took out a high-tech reagent tube emitting a light blue glow from its system space. "Host, this is a serum vaccine I picked up. I saw that Borui and those three guys all got it, and they're all in good condition and immune to the virus, so they won't turn into zombies. Do you want to get a shot first?"

Serum vaccine?

Jiang Chen frowned slightly, took it, and examined it carefully.

Just like in a science fiction movie, the reagent tube, which is more than ten centimeters long, looks very expensive and high-end.

"I wouldn't dare to use something of unknown origin on myself, although the fact that Bo Rui dared to use it means that it has already undergone human trials..." He paused for a moment, took out a simple black piggy bank from his space, and casually stuffed the serum vaccine into it.

Seeing this, the little white cat hurriedly stopped her, "No, Master! Borui said this thing is difficult to make and can't be mass-produced. Don't sell it, what if..."

Before it could finish speaking, the piggy bank beeped.

[Ding! An unknown serum vaccine, created with immense human, material, and material resources, possesses the ability to repair DNA mutations. However, if the body is not adapted, it may cause the opposite effect. Its value is currently being tested...]

[This item is worth approximately... 1 billion RMB in the current mission world. Would you like to redeem it? Friendly reminder: This item can only be redeemed in the current mission world. It will be worthless once the unknown virus loses its activity.]

"Meow meow meow? I can understand each word individually, but it's a bit hard to understand when they're put together." The little white cat's eyes started rolling in circles again. "The CPU can't keep up! Host, this thing is so valuable! Should we sell it?"

"Xiaobai, quickly retrieve the facial recognition data of those who received the serum vaccine last night and locate them using the recording equipment!"

The serum vaccine will have different effects depending on individual constitution. Since you intercepted 36 doses and the script did not change the ending, the only ones with potential risks are the four guys who received the serum vaccine.

Finding those four and eliminating them should solve the problem.

I'm heading to the East Coast now to make sure the zombie horde doesn't spread, then everything will be fine.

The fluffy little ball shook its fur, stroked its big, fluffy ears, and patted its chest, guaranteeing, "Host, I believe your assassin cat will complete the mission perfectly!"

After discussing their plan, Jiang Chen made an excuse to go out and buy food, then drove away, reminding the others not to go out casually and to prepare firearms and ammunition just in case.

The East Coast mentioned in the script is located at the easternmost part of this city. Due to the vague information, he couldn't determine exactly where the zombie virus leaked and caused the spread.

Affected by the online exposure of the incident, the east coast was deserted. People had gathered in the city to cause a ruckus, engage in panic buying, or hold demonstrations. Looking out over the vast coastline, the sea in the distance was as beautiful and calm as a blue mirror.

"Could the seagulls be spreading the virus?" Jiang Chen shaded his eyes with his hand, looking up at the white seagulls flying over the sea.

Why is the countdown so precise and rigorous?

The script has changed from 24 hours at the beginning to 5 hours now. If it were spread by birds, sea creatures or other means, it shouldn't be this accurate, right?

"Dirty, dirty, dirty..." Just as he was pondering this, a cargo ship in the distance sounded its horn, startling a flock of seagulls.

A freight company?!

A thought flashed through Jiang Chen's mind: the human trafficking partner on the resort island was Maruta Freight Company.

The company's CEO is the very person who commissioned the original owner to investigate his daughter's whereabouts!

As the saying goes, there's no story without coincidences. There must be a hidden story behind such coincidences in a feature film, right?

He felt he had grasped the key point and hurriedly drove straight to the nearby dock.

"Maruta Freight Company?" An elderly woman was sweeping up trash on the dock. She had a cigarette in her mouth and was quite satisfied with the premium cigarettes the handsome young man offered her. She smiled and pointed into the distance. "Hmm, that's one of the top freight companies. They have their own cargo holds and ship berths."

Maruta is very powerful; many cargo ships of all sizes come and go every day.

Some are for short trips, some for long trips, and quite a few staff members like to take their daily cargo ship to Lvdu Port…

The old lady was very talkative, rambling on and on, and finally pointed out the exact location of the Maruta Freight Company's private pier.

After traversing all the suspicious locations on the East Coast and finding no potential dangers, Jiang Chen parked his car in a secluded spot, closed his eyes, and waited quietly.

As cargo ships and passenger ships were unloaded and loaded, he inspected each one with his Horcrux.

It wasn't until nightfall, and as the time drew near to eight o'clock, that he got out of the car, put one hand in his pocket, and looked at the only huge cargo ship approaching the dock.

The cargo hold was labeled as transporting chilled meat, and the waybill listed chicken, beef, and other legitimate products. However, the cargo hold was filled with a pile of rotten animal carcasses!

"The meat processing plant is using inferior meat as its source?" Jiang Chen frowned as he "looked" at the information fed back by the Soul Weapon from a first-person perspective.

Several rotting dead dogs wrapped in plastic bags have begun to twitch slightly, clearly indicating that they have been infected with the zombie virus!

He suddenly realized why the script always ended with the world being completely destroyed three months later.

The zombie virus takes effect slowly on animals. When the infected animal carcasses on this ship were transported ashore, some of them quickly transformed into zombies and bit the workers, causing a large number of zombies to appear on the east coast and spread to the city. Some of the zombie carcasses that were transported by machinery and transformed more slowly were transported to meat processing plants.

Manufacturers that can use this type of meat cannot be expected to have adequate disinfection and high-temperature treatment measures.

Therefore, a large amount of food carrying the virus will flow into the market through mechanized assembly lines, and anyone who buys and eats it will be infected and turn into a zombie...

"Hopefully, stopping it will save the mission world." Jiang Chen ordered the Horcrux to grind all the animal carcasses in all the cargo holds of the ship into powder, and at the same time, he had the Horcrux take out a flamethrower from the system space and burn all the cargo holds to disinfect them.

After doing all this, he felt a splitting headache. It was clear that forcibly opening the system space of the soul weapon was too much of a strain on his mental strength. He had to lean against the car for a long time to feel a little better.

"Hurry, hurry, hurry! We can go home after we unload this ship!" The busy dockworkers, unaware that they had just escaped a disaster, ran up to him, smoking cigarettes as they went.

First, the bill of lading was handed over, and then the huge containers were unloaded from the cargo hold.

"Goods from Elion No. 2 Meat Processing Plant, the usual..." The worker in charge of unloading scribbled his name on the form, then opened the container while smiling and talking. However, what he saw next left him speechless. He paused for a few seconds, looking blankly at his colleague who was handing over the goods, "Where are the goods?"

The container was pitch black and smelled of something burning, but there wasn't a speck of dust inside.

The group stared blankly at the empty, stinking container for a long while. Then, the unloading workers grabbed the person in charge of the handover and shouted at the driver who was unloading the goods, "You're my witness, they didn't give us anything!"

Hundreds of tons of meat transported by Elion's No. 2 meat processing plant have all disappeared.

All the containers were dark and smelled of burning when they were opened. Disputes between the freight company and the meat processing plant were inevitable, but they soon stopped fighting.

Because of an unknown person, negative reports were exposed about Elion's No. 2 meat processing plant buying rotten meat at low prices and passing it off as high-quality meat, raising concerns about the food source and hygiene conditions, which led to a public boycott.

Maruta Freight Company was even more unfortunate, as the online reports of human trafficking and corpses being transported through their cargo ships on the resort island quickly put them in the spotlight.

"Meow~ Host, I've taken care of those guys. They weren't exactly good people anyway. I also exposed their shady dealings and made it look like they were fleeing from justice. Actually, I've already secretly stuffed them into the incinerator and turned them into smoke!" The fluffy ball licked its paws triumphantly as it happily reported, "The script is updating. This time, everything should be foolproof!"

........................

postscript.

After nearly producing zombie meat that would harm all of humanity, the Yili No. 2 meat processing plant faced a boycott from the entire internet and declared bankruptcy a few days later under pressure from all sides. The arrogant boss committed suicide by jumping off a building to apologize to the world, while other responsible persons were arrested and imprisoned.

Maruta Freight Company is deeply entrenched, and despite being condemned for human smuggling and other illegal activities, its foundation remains unshaken. Owner Owendo didn't even issue an apology, merely posting a clarification on the company's website—claiming that Maruta Freight Company does not engage in human smuggling or the sale of corpses, and that it will pursue legal action against those spreading rumors.

However, he didn't get to gloat for long. Two nights later, when he returned to his bedroom on the entire upper floor of the villa, Owendo discovered a huge freezer in the center of the room.

Inside lay a woman in her thirties with reddish-brown curly hair, a noticeable scar on her forehead, a small black mole above her right nostril, and a uniquely designed ring on her left hand.

He felt a chill run down his spine, a bad premonition creeping into his heart.

Owen staggered forward and leaned over the glass case, staring intently. The other person's eyes were closed as if asleep, their expression calm and serene. A label was affixed to the lower left corner of the glass case—"Health Experiment Subject X901, shipped from Lacagua State on May 21st, XX year."

"My God!" he cried out sharply. After a few seconds of stunned silence, Owendo frantically dialed his assistant's number, demanding access to the human trafficking files for those transported to the resort island on May 21, XX year.

Five minutes later, all the detailed information was sent to his email address.

With trembling hands, Owendo found information about his daughter, who had changed her name to Dorothy. In May of that year, after submitting her job application, she was tricked onto a smuggling ship and personally escorted to the resort island by her own cargo company.

No wonder someone saw her on the island back then, but then there was no news of her again.

Because of her excellent physical condition, the daughter was used as a test subject to test the new zombie virus...

The fiercely competitive Owendo, who only had this one bloodline left, was utterly despondent. No one knew what he was thinking, because the next morning, the villa's butler discovered that his master had gone upstairs and never came down again. They searched the entire villa but couldn't find him. Everything in the bedroom remained exactly as it was, as if no one had ever been inside.

After Owendo disappeared, a list of smugglers that he had kept on his computer was published online.

Refugees, homeless people, young people lured by fake job postings, abducted children... In just a few years, Maruta Freight Company colluded with Guardian Company to transport more than a million smuggled people and their corpses, committing crimes that are too numerous to count and cannot be punished.

The relevant authorities acted swiftly to dismantle the smuggling chain, Maruta Freight Company declared bankruptcy, and several high-ranking officials involved in human trafficking were executed according to law.

Bo Rui and three other attendees fled to evade their crimes and were never seen again.

With serum vaccine samples lost and critical data destroyed, recovering them from the lab is extremely difficult. Without the vaccine's protection, most researchers are filled with anxiety, fearing a virus leak and lacking sufficient safety guarantees, causing new research projects to be temporarily halted.

The bigwigs who were exposed for participating in the video conference of the crackdown quickly disappeared without a trace and died without a burial place.

The country that was conducting zombie research was strongly condemned by other countries, so it quickly replaced its president and swiftly resolved the follow-up issues.

"Whoosh! Host, the script is finally updated..." The little white cat had been waiting for several days, and finally got the news. It hurriedly grabbed the script and hopped to the back garden.

Jiang Chen and Julia were hunched over the table drawing up design plans, enthusiastically discussing where to build the doghouse.

Hearing the fluffy ball's reminder, he finally relented and made some notes on the paper. "Anyway, it can't be under the window. You can choose any other spot you like. We bought a pretty big plot of land, so we don't need to be so frugal and cramped. Let the doghouse be a little further away from our little house, otherwise it'll be too noisy at night if there's any rustling."

"Alright, alright, whatever you say!" Julia suppressed a laugh and drew a circle under the tree with her pen. "Let's set it here for now, but we'll have to check later to make sure there's enough sunlight..."

While browsing through the book, Jiang Chen glanced at the updated plot and couldn't help but raise an eyebrow.

The mission world has been salvaged, but the zombie virus still leaked and will sweep through the entire city two days later, trapping all residents with nowhere to escape.

Ten days later, the entire city of Belenta fell. To prevent the spread of the virus, the authorities dropped a small bomb, completely destroying the medium-sized city with a permanent population of nearly two million. The zombie virus and its newly built laboratory disappeared into the annals of history, and the entire mission world entered a state of free development.

"Take a look at the decorating style first, I have to go out for a bit." Jiang Chen checked the time, gave this instruction, and got up to walk towards the garage.

Julia tilted her head and asked curiously, "What's wrong? Why is it so urgent?"

"Yes, I have to go save the world!"

She couldn't help but chuckle, waving her hand and shouting, "Go on, great hero! Remember to come back and pick out the floor color after you've saved the world!"

"Beep beep!" Jiang Chen honked the horn to signal, then drove the car onto the street and started looking up information on his phone.

The fluffy little dumpling looked completely bewildered. "Host, couldn't we just take the others and leave before the city was locked down? What are we doing now?"

“Millions of people live in this city. What will happen to them if we run away?” Jiang Chen was at a loss after searching for a while, and tapped his fingers on the steering wheel idly. “We’ll exchange the problematic serum vaccines for money to eliminate the hidden dangers.”

Bo Rui and others also disposed of it;

That night, all the samples, test subjects, data, and other materials that were transported away were put into the system space, but the zombie virus still leaked out. The only possibility was that the laboratory was exposed.

Someone must have prepared the lab before the evacuation and transported a large number of samples. Where could it be hidden?

The little white cat tilted its head and thought for a moment, "Since the plot is to destroy this city and blow it up completely, it means that the laboratory and the virus haven't been moved yet and are still in this city. Host, let's use a tracking device!"

As it spoke, it scratched its round little belly twice and handed over a button from its paw.

One-time use C-grade item - follow the map.

Using this tool allows you to track people or objects at specific locations. The more detailed the information you input, the more accurate the location will be. The tracking is effective for ten minutes. Note: There may be errors due to unclear descriptions, so please treat the tracking results with caution.

"Hehe, all we need to do is enter 'zombie virus,' and then all possible locations will be marked, plus the recording equipment..." The little white cat grinned smugly.

Jiang Chen sincerely praised, "My little Bai is so capable, amazing! He's even figured out the effects of combining props. Let's not delay, let's start saving the people!"

The tool quickly marked the locations of the suspected zombie virus sites, totaling as many as thirty.

The little dumpling immediately saved the specific locations on the recording device and searched for them one by one.

Even so, despite Jiang Chen and the little white cat's efforts, they only managed to defeat a little over half of them. Then, researchers were infected by the mutated zombie virus and quickly turned into zombies, attacking others and spreading to the streets.
