Damn zombies, how dare they disguise themselves as humans!

It wasn't that Luo Tian was malicious and had no intention of wiping out an entire family.

If the survivors on the bus and the group of survivors escorted by Wu Qingshan spread the word about Su Rou and Chen Feng, and their families found out, would they let them go?

The answer is obvious.

If you are too soft-hearted, you may very well be the one who dies.

Besides, birds of a feather flock together. If Su Rou and Chen Feng have such character traits, what kind of good people must their families be?

He feels no psychological burden at all when killing this kind of person; on the contrary, he feels great, which completely surpasses the pleasure of killing zombies.

[Cleanup complete]

[Target: Chen Feng (deceased)]

[Level: C]

The rewards are as follows.

[1. Points +30]

2. Staple Foods

[3. Choose one: a random reward or a stealth skill]

"Only 30 points..."

"Stealth skill?"

Luo Tian quickly glanced at the rewards screen.

You can roughly tell what type of skill it is just by looking at its name.

I silently checked the skill description, and as expected...

[Stealth: Active skill. Isolates you from external presence and allows you to move stealthily by refracting light. Lasts 10 seconds, 2-minute cooldown.]

"It really is invisible."

"Another life-saving skill!"

"No! It should be something that can both save your life and kill enemies, making it even more practical than speed."

After reading the introduction, Luo Tian immediately selected the skill.

Soon, the moment the system notification sounded in his mind, a cool current suddenly burst forth and swept over his entire body.

Furthermore, the meridians felt slightly swollen, but not painful, and there was a strange feeling that all the pores on the body were opened and then immediately closed.

Once the icy sensation completely disappeared, Luo Tian clearly felt as if an invisible barrier had appeared inside his body, automatically concealing his aura and hiding his form.

"Give it a try."

Luo Tian couldn't help but stand up and walk towards the iron gate in the distance.

The iron gates on the rooftops of these buildings are all similar; they are all aluminum alloy security doors.

He first peered through the gap in the door to make sure there was no danger before opening the iron door and cautiously walking down with his dagger in hand.

This six-story residential building has two elevators serving three households per floor.

After months of zombie outbreak, the power supply was completely cut off, so the elevators were naturally unusable.

The doors of the three households on the sixth floor were all open. The people inside had either turned into zombies, been rescued by the army, or escaped the city on their own.

Luo Tian randomly walked into one of the houses, carefully searched the messy room, and after finding no zombies, went into the bedroom and stood in front of the dressing mirror.

"sneak!"

The thought just occurred to me.

The invisible barrier within his body instantly burst open.

The light that had been bright before my eyes dimmed slightly.

Looking down, Luo Tian could still see his hands, feet, and body.

But the reflection of myself in the mirror vanished into thin air, which felt both strange and eerie.

He was standing in front of the mirror, but he couldn't see himself in it, and even the dagger in his hand had completely disappeared.

After 10 seconds, the stealth mode disappeared, and the reflection in the mirror instantly appeared.

After glancing at it, Luo Tian turned and left the bedroom, then walked down the corner staircase to the next floor.

Within the city, the two things that could pose a threat to him were his mission targets and zombies.

In addition to their special senses, zombies can also use their keen sense of smell to locate living people.

Although the description of the stealth skill states that it can make one invisible while also isolating one's own presence, I definitely want to try it out and be fully aware of its capabilities.

Upon arriving on the fifth floor, I quickly circled the three houses, which were also in a mess, but did not see any zombies.

There's still nothing on the fourth floor.

It wasn't until he reached the third floor that Luo Tiancai finally discovered a large, obese zombie in the room.

It was probably infected by an airborne virus; its obese, pale body showed no signs of being bitten and remained intact.

It was standing blankly in the living room with its lifeless, pale eyes, and no one came to attract its attention. It had probably been standing there for several months.

Once the cooldown period is over, Luo Tian will use it again immediately.

I arrived at the door and took a look around.

"I really can't smell it."

With a zombie's sense of smell, it's impossible for them to remain indifferent at this distance.

However, Luo Tian did not let his guard down. He raised his dagger, ready to use Swift Movement at any moment, and cautiously and quickly approached.

One step, two steps, three steps, four steps...

Luo Tian walked right up behind the fat zombie, then went around to stand in front of it. He even waved his dagger in front of the dead fish's eyes, but it still didn't move.

"It can indeed make you completely invisible to zombies."

"It's very useful, but it only lasts for 10 seconds."

"Fortunately, the cooling-off time is short, only 2 minutes."

Silently counting down in his mind, and seeing that there were only three seconds left, Luo Tian immediately raised his dagger and aimed it at the forehead of the fat zombie.

"laugh!"

The dagger was plunged into his head, and then twisted violently.

But at the same time, the dim light in the field of vision suddenly returned to normal.

This is clearly a result of manifestation.

"Attacks will break stealth?"

"No, it should be that the invisibility failed because it was contaminated by something."

Luo Tian looked at the dark black bloodstains remaining on the dagger.

It was probably these bloodstains that made him visible from his hiding place.

In this way, the only option is to use stealth to instantly kill a single target.

But it's already very powerful.

There's no need for a second strike when dealing with a human target.

This skill is unnecessary when dealing with zombies; using it is a waste. If there are only a few, you can simply kill them head-on.

Back on the rooftop,

Luo Tian opened his information interface.

He glanced at it and saw that both conditions were met, so he didn't hesitate.

"System, upgrade search."

Upgrade requires 100 points (already met), and completion of five C-level cleanup missions (already met). Please confirm.

"confirm!"

[Search function upgrade confirmed.]

[Upgrading...]

Upgrade complete.

The search function was a system feature, so Luo Tian was completely unaware of the upgrade.

"The search function has been upgraded, the mission objective has been raised to level B, and the job level has also been raised to level B."

"It seems that profession and search level are in sync."

"The points required for intermediate searches have doubled, and the search range has also doubled. You can also specify B-level and C-level targets for search."

"The next level requires 500 points and 10 B-level missions..."

"Earning points isn't difficult, it's just that the number of tasks is a bit of a pain."

"But it's really nothing, just 10 times and 10 people."

After closing the interface, Luo Tian didn't waste any time and immediately began to silently search.

[Consuming 20 points, starting the search for targets to be cleared.]

[Searching...]

Search complete.

[Two targets have been detected within a two-kilometer radius and are awaiting elimination.]
