Damn zombies, how dare they disguise themselves as humans!

"The evaluation is spot on."

"Fools are courting death, and they end up dragging a lot of innocent people down with them."

"And the most hateful thing is that they think they're not wrong, and everyone else is wrong."

"If everyone in this world were like that young man, how wonderful it would be? If you want to save someone, go save them yourself; if you want to die, go die yourself."

Looking at the file information interface in front of him, Luo Tian thought for a moment:

"In this mission, the main threat comes from the small zombies that become infected and mutated at night."

"Normally, it should be the target; killing it would eliminate the threat."

"But the system task's target for cleanup is Wang Xiulan..."

"Is this to nip the problem in the bud? To prevent future troubles?"

"My system class is a street cleaner, so that's the meaning of being a street cleaner?"

It is very difficult to change a person's heart and nature.

Just like Wang Xiulan, if it weren't for her, she wouldn't have been bitten and infected by the little zombie, causing everyone to die, and she would have survived by sheer luck.

So next time, if she doesn't repent, she will definitely continue to save other bitten children, escape with the crowd, and then kill a second group of people.

If she survives the second time, there will be a third, a fourth, a fifth time...

In other words, the longer such a person lives, the more people they will kill.

The same goes for Su Rou last time, as well as that middle-aged woman and man. They were all mean-spirited, selfish, and self-serving. They used morality to blackmail others and ignored the sacrifices of others. If they hadn't died, they would definitely have killed others, and it might have even caused some kind of large-scale and tragic death or injury.

What I, as the post-apocalyptic cleaner, have to do is to clean up these parasites in the post-apocalyptic world.

"Actually, it's pretty good."

"Killing these kinds of people is even more satisfying than killing zombies!"

Having completed four missions and eliminated those reckless targets, Luo Tian felt quite satisfied.

The more hateful the target, the more satisfying it is to eliminate them.

After closing the file information, Luo Tian opened the rewards interface.

[Cleanup complete]

[Target: Wang Xiulan (deceased)]

[Level: C]

The rewards are as follows.

[1. Points +50]

2. Staple Foods

[3. Choose one: a random reward or a self-healing skill]

"My points have increased a bit since last time, reaching 50."

"Skill……"

"Self-healing?"

Luo Tian silently checked the skill information.

[Self-healing: Passively triggered, it can quickly stop bleeding and heal injuries, and prevent wound infection from worsening.]

The introduction was simple, but it caught Luo Tian's eye.

In a post-apocalyptic world teeming with zombies, it's inevitable that he'll get bitten. Although he can become immune to the virus and avoid turning into a zombie, the wounds won't disappear. Plus, with his mission of going wherever danger lurks, clearing out targets can't always be smooth sailing. If you walk by the river long enough, you're bound to get your shoes wet.

If an accidental injury is left untreated or cannot be treated, it may worsen over time and could even lead to death.

Even in peacetime, many people die from tetanus, let alone in a post-apocalyptic world where medical care and medicine are scarce.

But with this passive skill, you no longer need to worry about this problem.

Without the slightest hesitation, Luo Tian immediately said:

"Claim your reward."

"Choose self-healing skills."

[Ding! Reward is about to be issued.]

The next second, Luo Tian felt a chill burst forth within his body, rapidly spreading throughout his entire being, almost causing him to shiver uncontrollably.

This feeling came suddenly and disappeared just as quickly, returning to normal in the blink of an eye.

Luo Tian had gotten used to this, because every time the system rewarded him with a skill, he would experience all sorts of strange sensations.

Especially with skills used proactively, in addition to the abnormal sensations transmitted by the body, one will also gain some kind of insight, thus instantly mastering this ability.

Just like the Swiftness skill, when used, it quickly mobilizes one's energy and spirit, which is equivalent to squeezing one's own potential to temporarily burst out the body's limits. This is why there is an 8-second time limit. Any longer will cause excessive physical and mental consumption, resulting in weakness or even coma. The 3-minute cooldown means that it takes 3 minutes to recover from the loss.

His current passive self-healing ability is probably due to the system modifying his body's genes, giving him the ability to heal wounds quickly.

"I wonder how effective it will be."

"I really want to cut myself."

Luo Tian raised his arm and looked at it, his right hand holding the dagger, looking somewhat eager to try.

But I gave up quickly, for no other reason than the pain.

Besides, you'll get hurt sooner or later, so why torture yourself now?

"It would be perfect if you could reward us with a skill that reduces pain sensitivity to zero."

"Or just become immortal, the kind where your head is cut off, you're dismembered, blown to bits, and you can still regenerate."

Although it may not be very practical, you should always have dreams, otherwise what's the difference between you and a salted fish?

120 points.

"I have enough points. I can upgrade the search function and explore B-level targets after completing one more C-level mission."

"After taking down a B-rank target, the upgraded Guardian skill will become something else entirely, though I don't know how it will turn out, but it's definitely going to be stronger."

After checking his personal information, Luo Tian looked up at the city shrouded in darkness and the occasional howls of zombies.

After thinking it over, he decided to suppress his eagerness and give up trying again.

After staying up late, I'm exhausted. If I accidentally make a mistake in this state, it would be a huge loss.

After putting away the survival rations he had just been rewarded with, Luo Tian found a corner on the rooftop, sat down against the wall, held a dagger, crossed his arms, and closed his eyes to rest.

I had barely closed my eyes—

"roar!!"

A hoarse roar suddenly jolted him awake.

But the sky was already beginning to lighten, signifying the passage of time.

"A few hours have passed in the blink of an eye, time really flies."

Having survived in this city for several months, Luo Tian had long been accustomed to the sounds of zombies. He had just reflexively jumped up when he saw that the rooftop was empty and posed no threat. He then relaxed his tense body, moved around a bit, and felt his slightly refreshed spirit before taking out the survival rations from his pocket.

"System, could you please change the survival supplies?"

"It's this stuff every day, it's really hard to swallow."

As he ate the tasteless energy bars, Luo Tian couldn't help but complain.

Of course, this is just a bit of a rant. Compared to the survivors in the city, he is undoubtedly lucky, at least he doesn't have to endure hunger and risk going out to find food.

Eat quickly

Luo Tian didn't waste any time either.

"search!"

[Consuming 10 points, starting the search for targets to be cleared.]

[Searching...]

Search complete.

[Three targets to be eliminated have been detected within a 1-kilometer radius.]

[Target 1: Due east, approximately 60 meters, Class C target.]

[Target #2: Northwest direction, approximately 250 meters, Class C target.]

[Target #3: Southeast direction, approximately 500 meters, Class C target.]

[Target #4, southwest, approximately 900 meters, Class C.]

Please select one as your tracking target.

"Target number 1, 60 meters?"

"So close?"

Luo Tian quickly arrived at the east side of the rooftop.

Below it was a street, and sure enough, a group of people ran out from the end of the street.

There weren't many, maybe a dozen or so.

Behind them was an overwhelming, dark mass of corpses.
