But Lin Cheng, who had just arrived here, didn't want to let Coke come like this, so he kicked it lightly to signal that he would stay here, and then slowly took out a dagger forged by 'black jade' from behind his waist, and slowly touched it in the direction where the footsteps came from just now.

He, Bai Ling and Coke had obviously searched all the buildings in the vicinity before the sky was completely dark, although they didn't search too carefully because they had too few people and too many buildings, but with the current strength of the three of them, as long as there were people in the house, they could also detect the breath of living people through the wall, so this was also the strangest place he felt, obviously it was determined that there were no living people in this vicinity, but how did the slight but extremely real footsteps come from just now?

Feeling that the situation seemed a little weird, Lin Cheng raised his spirit, his body tensed, and slowly walked downstairs along the stairs.

And the moment he walked out of the capsule room, the footsteps never sounded again, as if the owner of the footsteps had already noticed his presence the moment he opened the door, and now he was secretly dormant, and he couldn't figure out which corner he was waiting for him to send to the door.

It was precisely because of this consideration that Lin Cheng did not dare to relax his vigilance at all, even if his current strength and equipment were absolutely countereffective even if he was attacked by the opponent at close range, he still didn't want to give the other party a chance.

Slowly descending to the fourth floor, seeing that the footsteps still did not sound again, Lin Cheng secretly frowned, thinking that this guy should not really be so rebellious, right?

When he opened the door of the capsule house, it could be said that he had suppressed the movement to a minimum, and Coke lying at the door did not make any sound from beginning to end, even if he was not able to detect that he had come out when he encountered this situation, could it be that the other party could be more sensitive than his sense of smell of danger?

But it's not a matter of being frozen like this, since there is movement, it means that there are definitely living creatures in this city, whether this living creature is a human or a monster, it is necessary for him to 'invite' the other party out, because if he wants to find information in such a dead city, unless he encounters a person or monster who has lived here.

Standing in place and deducing in his mind the specific location where the footsteps might have come from just now, relying on his perverted memory reorganization ability, he finally deduced that the footsteps just now should have come from the corridor in the northwest corner of the second floor, which is just below the corridor leading from the second floor to the third floor.

After determining the location, Lin Cheng no longer hesitated, and continued to go down to the second floor according to the rhythm just now, and after going down to the second floor, he squinted his eyes and glanced at the dark corner under the stairs, and after finding that there was nothing there, he couldn't help frowning slightly.

"Da ......"

Suddenly, just as he wanted to get closer and search closer, a familiar sound of footsteps suddenly came again, and this time the footsteps were no longer from that corner, but less than a meter from behind him!

"Shh——!h

Without even thinking about it, Lin Cheng, who had been holding the black jade dagger, directly turned around and swung it back the moment he heard the footsteps, and even if the force of the swing was already controlled, it was enough to seriously damage any monster!

But what he didn't expect was that his confident swing was all slashed into the air, and when he turned to look, he found that there was no monster behind him, there was not even a ghost at all, and the footsteps were like ghosts transiting, and after passing it was a burst of nothingness.

“……”

Lin Cheng naturally didn't believe that he had encountered a ghost, there were thousands of strange things in this apocalypse, but he didn't think that ghosts would appear in it, since he obviously heard the footsteps and turned around but didn't see anyone, it could only mean one thing, the position of this footsteps was lower than he imagined!

Thinking of this, Lin Cheng directly lowered his head to the ground and looked at it, and then felt his heart tighten suddenly!

It turned out that on the floor not far in front of him, there was a group of rats with black fur rushing to the staircase leading to the first floor, these rats were bigger than the other, the largest one was almost as big as half the size of the Coke, and the most strange thing was that although the group of rats ran fast, they did not make a sound, like a group of ghosts crawling quickly on the ground.

As for the footsteps that sounded twice, when he saw a broken leather shoe being pushed back and forth by this group of giant mice, the corners of his mouth couldn't help but pull a wry smile, and the so-called footsteps for a long time were just accidentally bumped into by this group of rats when they migrated, and he didn't pay much attention to his feet, so he didn't find this problem at the first time.

The rats came and went as fast as they could, and in less than a minute, the astonishingly large rats had disappeared at the top of the stairs, leaving only the tattered leather shoes that had been pushed back and forth by them in place.

"It turns out that this group of rats is running out in waves, and I said why didn't I see it when I first came down."

After picking up the leather shoes and taking a few glances, after making sure that the footsteps just now were indeed made by this leather shoe, Lin Cheng shook his head a little speechlessly, and then threw the leather shoes to the ground, and was about to go back to the capsule house to continue resting, but suddenly remembered something, turned around and walked towards the corner of the stairs behind him.

Because he suddenly realized a problem just now, how could this city be just an empty city, how could it give birth to such a group of rats that can be called fat?

You know, just counting the wave of rats that passed under his feet just now, there are almost thirty, although the size of these rats is uneven, but without exception, they are five to ten times larger than ordinary mice, such an unscientific body shape is not comparable to even the oil rats in the back kitchen of the restaurant, so Lin Cheng wants to search the location where they just appeared to see if he can find any unusual clues.

Walking to the bottom of the stairs, because the height was too low, Lin Cheng could only bend down and squat on the ground, took out a flashlight and shone it around, but found that there was not even an ant hole here, let alone a mouse hole.

"Tsk, that's weird......"

After carefully searching along the wall for a long time, Lin Cheng, who still found nothing, stopped, frowned and muttered to himself, according to the size of the group of rats just now, if he wants to appear in large numbers, there must be a small mouse hole nearby, but no matter how he searched, he couldn't find any clues at all, and the group of rats seemed to appear out of thin air, which made him puzzled.
