To be precise, as long as he didn't get closer than about half a meter to them, even if he walked right in front of a zombie, it wouldn't pay him any attention, as if he were invisible.

However, this half-meter distance wasn't the same for all zombies.

During one of his tests, Kim Haru found that a zombie, clearly of a higher level than the ordinary ones, reacted to him earlier.

The reaction range for this one was about a meter.

Perhaps the higher the level of the zombie, the further it could sense him.

Kim Haru was quite pleased with this discovery.

But since his experiments were limited, Kim Haru wasn't confident he could escape unscathed in front of a higher-level zombie.

Even with that one-meter zombie, he only managed to avoid danger by reacting quickly and getting out of range.

So, he hadn't been able to draw any firm conclusions about the relationship between distance and zombie levels.

As for how he gained this ability, Kim Haru had his own theory.

Before he arrived, the body of the original Kim Haru had already been confirmed dead.

However, when his soul merged with the body, it created a new state.

Somewhere between dead and alive.

He looked and felt like a living person, but to the senses of zombies, he was just another corpse like them.

This led to the development of this peculiar skill.

After realizing this, Kim Haru started to worry about whether he should even try living in a safe zone.

Even though he didn't seem any different from a regular person right now, who knew if the safe zones in this world could detect the difference between him and the zombies?

From the original owner's memories, Kim Haru learned that every safe zone had equipment to check whether someone was a zombie or not.

But if he didn't go to a safe zone, it wasn't as if he could blend in with the zombies either.

What would he do after that?

Unable to come up with a solution, Kim Haru decided not to overthink it for now.

He'd take things one step at a time.

At the moment, he didn't even know if he could find food; he might starve to death soon, and then he wouldn't have to worry about where to live at all.

Climbing down from the wooden bed, Kim Haru casually ran his fingers through his hair, tidied his clothes, and grabbed the steel pipe before opening the door.

No matter what, he still had to keep looking for food.

Since he had become more familiar with searching and avoiding zombies, Kim Haru moved much faster today than in the past two days.

In no time, he had almost finished searching the entire street, but he still hadn't found a single bite of food.

The sky began to darken.

Kim Haru looked toward the other streets, just as desolate and ruined.

He knew in his heart that those streets would be in the same condition.
