Xia Na's coat was placed in a corner of the pile of debris. Ling Mo thought she wanted to cover something, but after carefully opening it, she found nothing.

"Was it forced to leave it here?" Li Yalin guessed.

"There is no trace of damage on the clothes, which is obviously taken off by Xia Na herself... What kind of danger can be solved by taking off her coat..." Ling Mo said, turning the coat over again.

"Well..." Li Yalin immediately frowned.

"There is nothing left... Is it really just left here? Since the focus is not on the coat, then..." Ling Mo put down the coat and turned his eyes around, "the reason why Xia Na did this should be to identify something..."

Just thinking about it, he seemed to see something in the corner of his eye

Ling Mo quickly turned his head, and then reached out to touch the ground.

"Here is... Xia Na's clothes were just put next to this... Huh? Is it the word?"

He followed these traces and immediately showed a strange look.

Sure enough, it was a line of very shallow words... Judging from the size and depth, it should be quickly carved by Xia Na with her nails. Combined with the identification method she adopted, it is not difficult to guess her situation at that time.

"Since she's in such a hurry, it means she hasn't lost the thing... But from another perspective, in such a hurry, she still has to take time to leave these messages... That is to say, this line of words is very important."

Ling Mo thought. His eyes have begun to recognize it carefully.

The "ground" here is full of coarse cement particles, even after being ground. It still looks like this to the naked eye. If it weren't for the fact that almost all the surrounding areas were filled with plasma, but there were some small gaps in these handwriting, Ling Mo wouldn't find it so soon.

If it were normal, Xia Na would think of a more secure way

"It's about these bodies..." Ling Mo murmured in his heart.

When he looked up, he just heard Li Yalin saying, "if you get wet..."

"Ah?" Ling Mo was confused.

"Hey, didn't you ask me..." Li Yalin suddenly felt a little wronged.

"You really want to!" Ling Mo shook his head, pointed to the handwriting and said, "Xia Na is to remind us. Don't just pay attention to this pile of debris."

"Well..."

"In fact, you just thought of this problem." Ling Mo said.

Li Yalin was stunned, and then asked excitedly, "really? What is it?"

Although she looks sexy and tall enough, this student sister is also very cute when she occasionally shows a little woman's side... Especially when she gently taps her chest with her hand, causing a surge of waves in her chest

"Really." Ling Mo moved his eyes quietly. His mouth said, "no matter from which point of view, these debris should not appear here, right? But in fact, it's just because our minds are imprisoned by these channels. Sister, do you think you can only enter these channels through the electric elevator well?"

"Isn't it?" Li Yalin asked back.

"This is what Shana is going to tell us. She said that there must be other entrances and exits in this building, and there must be more than one. Elevator shaft. It's just their initial excavation channel. Although they will often use it, it's more convenient for them to find food from other entrances and exits?" Ling Mo explained.

Li Yalin "ah", opened her eyes wide and said, "so they can go anywhere in the building at any time?"

"That's what it means. I guess that the reason why they can coexist peacefully with the zombies in this building is mostly based on some special reasons, such as the relationship between ordinary zombies and head corpses. But in the end, it's hard to infer the truth without knowing what these creatures are." Ling Mo then said, "and the zombies in the building are not unaware of the existence of these 'neighbors', but they will never step into these passages. We have verified this before in the elevator. Since there are many entrances and exits, it is clear why I felt monitored before..."

"It's because we are invaders." Li Yalin tilted her head.

"Er... Can't refute."

Ling Mo is a little embarrassed. This kind of words from the mouth of the zombie make people feel taken for granted. But as human beings, they always subconsciously avoid this

"Even if the race is different, I still don't want to admit it frankly..."

Li Yalin seemed to see something, and suddenly smiled: "this is competition. Anyway, our zombies won't mind this kind of thing, or we should say the opposite... We are looking forward to this kind of thing. The prey that came to the door, and the battle that broke out between them... Thinking about it, we all feel blood boiling!"

"Calm down..."

Ling Mo then frowned again, suddenly pointed to the bone where she saw the tooth mark just now and said, "also, Xia Na asked us to pay attention to the trace on it. She said she had no time to observe it, but if we catch up, we must understand it first. Also... She said this might be a very interesting place..."

"I don't understand..." Li Yalin shook her head.

"Don't be so demanding for people in a hurry! But I think something's wrong. What I'm interested in for Xia Na... It can't be a good place..."

Ling Mo sighed, stared at the tooth print and said, "sister, come and have a look."

"What do you want to see..."

"It depends on the difference." Ling Mo said.

In terms of understanding zombies, Ling Mo is still not as good as these real zombies... But only he can discuss with zombies like this. Like Lao LAN, he can only stare at the corpse and talk to himself

"Is it different..." Li Yalin looked at it very carefully for a while, suddenly gently opened her mouth and knocked her teeth with her hand, "look."

In fact, at first glance, the teeth of zombies are no different from human beings. The more advanced the zombie is, the more difficult it is to see the difference from outside the eyes. But the low-level zombies are different. Their grinning appearance is completely exposed at the first glance

Like Li Yalin, although she mingles with humans every day, no one has found these details on her body

Compared with ordinary humans, Li Yalin's tiger teeth are slightly sharper, and all the teeth behind the tiger teeth look sharp. This shape is just for the convenience of the Zombie's bite
