Finally, the footsteps outside the door sounded again, and it began to slip into the distance. Cheng Yong exhaled lightly, and just put down his hanging heart a little, the footsteps came back again. This time it didn't stop outside the operating room, but walked straight over, and then a second footfoot, a third, and countless footsteps rang out.

Cheng Yong slowly retreated in a low posture, his gun always facing the door, until he retreated to the door where they came in. Just as he was about to beckon Huzi to evacuate the same way, the same footsteps sounded behind him. Gently closing the door, the two of them squatted in the corner of the wall next to the operating table, staring at the two doors one after the other. Outside the door was the sound of walking back and forth, clicking...... Click......

The two of them squatted in the corner, not daring to take a breath.

Suddenly, because the squatting posture was not very comfortable, Cheng Yong moved his legs slightly, but he didn't expect the barrel of the gun to touch the bed frame, and the bell rang and vibrated back and forth in the room.

The zombies outside the door stopped for a moment, and then slowly gathered at the door of the operating room, as if searching for something. Both of them pressed their fingers on the trigger, and the thin door would definitely not be able to block the impact of the zombies, and they were ready to fight to the death.

However, this time the zombies didn't seem to intend to give them a chance to behave, they gathered at the door for a while, and then gradually dispersed without hearing any movement. But they had no intention of going far, so they just dangled in the hallway.

Cheng Yong and Huzi hid in the operating room for a long time, but they still didn't wait for the time to escape.

The hands on the watch were quietly pointing to six o'clock, and the sun outside must have been close to the horizon. They have missed the opportunity to flee. The two of them had relaxed from their initial vigilant posture, sat on the ground against the wall, silently endured the hunger in their stomachs, and soon fell asleep in a daze.

In the middle of the night, Cheng Yong was suddenly awakened by a sound of scratching the door, he pushed the tiger next to him, but unexpectedly found that the tiger had curled up in a ball, and seemed to be trembling slightly. Cheng Yong pushed him twice, Huzi was awakened, stopped trembling, patted the back of Cheng Yong's hand, and signaled that he was fine. In the dark, Cheng Yong didn't see that Huzi, who had always been very aggressive, was full of tears at this moment.

The scratching of the door continued, and then turned into a violent banging on the door. Huzi touched the gun next to him, but found that Cheng Yong did not pose as ready to fight.

"Next door." Cheng Yong whispered in Huzi's ear.

Syllable......

The door next door didn't last long before it collapsed. A jumble of footsteps rang out next door, and the zombies roared, their voices tinged with bloodthirsty excitement, and then gradually fell silent. In the dark, Cheng Yong and Huzi glanced at each other, not knowing what could make the zombies react so abnormally next door, except for the furnishings of the operating room, there were only a few corpses left there before.

In the darkness, the sound of tearing flesh and chewing sounded, and through a thin wall, it seemed to be behind the ears of the two. There were zombies fighting and even fighting, but soon only the sound of gnawing remained, which lasted until eight o'clock in the morning, and the next door gradually quieted down. The two of them never fell asleep again, and after listening to the night of creepy sounds, they both felt exhausted at the moment.

Silence had returned outside, but they hadn't heard the zombies leaving the next door, they had gone dormant after the next door had eaten their fill.

"Do you want to go?" Huzi asked softly.

"Let's go!" Cheng Yong said.

"Kill it?"

In the dark, Cheng Yong glared at Huzi: "Are you stupid, if you can kill it, you still have to wait until now?" Of course, go out quietly and don't alarm the zombies. ”

Cheng Yong continued: "We can't go back the way we started, we will pass by the door next door." We went out of another corridor and looked for other exits. ”

He gently unscrewed the door and looked out, the corridor was wider and as empty than yesterday's, and it seemed that the zombies who wandered here last night were now all next door. The two crept down the hallway along the wall, their flashlights covered in a layer of clothing, and only a faint light came through.

The ground was full of debris, and they had to be careful to avoid them, looking for gaps to put their feet on. In just a short distance, the two felt like they had walked for a century. To make matters worse, they found that there was no exit from the corridor.

"It's not scientific!" Huzi said: "Look at this layout, yesterday's corridor was a staff passage, and this should be a patient passage." The passage for the sick must have its own entrances and exits. Is it on the other side? ”

Cheng Yong patted his head: "The two of us are really stupid, do you remember the closed glass door at the entrance, it must be the passage for patients to enter." We still have to go back. ”

"Mom, that's not going to pass through the zombie door." Huzi shrunk his neck.

"Let's keep it quiet, we hope we don't wake up the."

The two of them tiptoed back to the room where they had just departed. The door next door was wide open, and from inside came the sound of muffled breathing.

Cheng Yong paused at the door, and Huzi patted him on the shoulder, signaling that everything was OK. The two of them crept along the corridor wall, not daring to pant too hard. Fortunately, there was no danger, and they reached the entrance without any problems.

The automatic glass door was closed as tightly as it was yesterday.

"There's no power now, this door can't be opened." Huzi pressed the open button on the door. I accidentally kicked a chair upside down in the doorway. Then the door opened automatically, making a creaking sound.

"Let's go!" Cheng Yong pulled the tiger over, and the two ran all the way into the corridor. In the darkness, several shadows ran to the door, gasping for breath and listening to the movement in the building. The two of them walked lightly and quickly, and they had already run to the first floor in an instant. The shadows listened to the faint footsteps, seemed to wonder the source, and finally disappeared into the darkness.
