The surroundings were extremely quiet, and Shen Yan'er could clearly hear the sound of her muddy breathing, which had become heavy due to nervousness. I don't know how long it took, but it remained frozen, and there was a low sound of footsteps in the depths of the silent tunnel.

"They're coming......" Xiao Hei grabbed Shen Yan'er's shoulders and put his lips to Shen Yan'er's ear to speak. He kept his voice very low, for fear that raising it a little would alarm the terrifying monsters that were slowly approaching.

The number of them was two, and they did not run, but walked slowly, but at a noticeably faster pace than in the mass graves.

Realizing that the danger was approaching, Yu'er and Jinghao hugged each other tightly in fright, not daring to let out any more screams, and the sound of fearful and nervous inhalation leaked from between their clenched teeth. If it weren't for the dead silence around him, no one would have heard Cheng dù's voice at all.

Don't be afraid. Shen Yan'er, who was in a cold sweat on her forehead, comforted herself. Yu'er and Jinghao were locked in cages, and she and Xiao Hei were blocked behind the bar, so even if the walking corpses rushed over, they couldn't hurt any of them. Although it is impossible to save Yu'er and Jinghao, at least no one will be injured, which is a great luck in misfortune.

"You stand back." Xiao Hei grabbed Shen Yan'er's shoulders and moved her behind him to protect her. Black's subtle voice and gentle movements still didn't escape the ears of the walking corpses, and the footsteps from the depths of the tunnel were noticeably faster, accompanied by a demonstrative-like roar, it seemed that they had spotted the "prey" in front of them.

Xiao Hei immediately pulled out the short knife he carried with him and struck the iron bar in front of him hard. He was no longer afraid to make noises, but deliberately wanted to use them to attract the walking corpses.

The fierce beating sound is like a beating drum, and the tempo is getting faster and faster. The provoking walking corpse let out an angry roar and rushed towards Xiao Hei like a beast.

In the blink of an eye, only two loud "clangs" were heard, and the walking corpse more than ten meters away crashed into it like a cannonball. If it weren't for the iron barricade, I'm afraid they would have pounced on Xiao Hei like hungry wolves.

Shen Yan'er was so frightened that she took three steps back. Knowing that the walking corpses couldn't bite him, he was still frightened by the ferocious posture of their pounce and subconsciously dodged. Even Blackie gasped, as if he couldn't believe that the walking corpse was running so fast. However, he quickly calmed down, grabbed the short knife in his hand and plunged it into the head of the walking corpse.

Perhaps because of his panic, he forgot Shen Yan'er's reminder just now, and stabbed the first knife on the forehead of the walking corpse. The sound of "dang" was hard and crisp, like the sound of a chisel chiseling into a rock. Xiao Hei's hand holding the knife was actually shaken open at once.

"Aim them in the eye!" Shen Yan'er, who was diagonally behind, roared in a hurry.

In the darkness, not to mention the eyes, even the outline of the body of the walking corpse could not be seen clearly. If it was replaced by Shen Yan'er, even if he knew the weakness of the walking corpses, he would not be able to kill them, but Xiao Hei was different, after listening to Shen Yan'er's words, he was like a cat with night vision, and he stabbed straight into the eye socket of the corpse.

The walking corpse let out a scream and retreated in panic with its shaky steps. At this moment, another walking corpse pounced again, and stretched out the iron fence with its eagle-like hands to grab Xiao Hei.

Xiao Hei took the opportunity to grab its wrist and tug it forward. The walking corpse wailed, and its entire body was pressed against the iron bar. Xiao Hei stabbed down again, accompanied by a sound of blood, and the walking corpse stopped all its movements and stopped struggling.

In the blink of an eye, both walking corpses have been killed by Xiao Hei. The silence of the tunnel was restored. Shen Yan'er's clenched heart finally returned to its original state, she took a deep breath and walked behind Xiao Hei. At this time, Yu'er and Jinghao in the iron cage also came back to their senses, and anxiously shouted and asked, "Sister, where are you!" "Miss, are you okay?"

"Fortunately, there is Xiao Hei here, and the walking corpse has been killed by him." Shen Yan'er responded to them, calmed down, and began to pull the chains again.

There was still blood spurting from the walking corpses on the iron bar, and the pungent smell of blood was in the air. The danger just now made Shen Yan'er's confused head feel like a basin of ice water had been splashed, and she calmed down suddenly. Her thoughts became clearer, her movements more composure, and in a few moments she untied the messy chains.

"Great." When the last circle of chains wrapped around the iron bar door was also untied, Shen Yan'er couldn't help but let out a sound of relief.

She threw a large mass of heavy chains to the ground, and together with Xiao Hei, she pulled open the iron barrage door with force, and rushed to the iron cage where Yu'er and Jing Hao were locked up as fast as possible.

"Sister......" Yu'er stretched out her hand from the cage, grabbed Shen Yan'er's clothes, and was moved to tears. Jing Hao also lowered her head to wipe her tears, and let out a whimpering and sobbing.

"Don't be afraid, we'll get you out right away." Shen Yan'er said as she groped around on the iron cage.

"The cage is locked." Xiao Hei's voice came from beside him.

When Shen Yan'er heard this, she immediately reached out to touch Xiao Hei's location, and immediately touched a pillow lock that was slightly larger than the palm of her hand. After pulling hard a few times, the pillow lock did not move at all, and it seemed that it could not be opened without a key.

Shen Yan'er, who was unwilling to give up, pulled out the bloody jade sword and slashed at the lock a few times. Although a few sword marks were cut, they still couldn't be opened. Continuing to cut down may attract other walking corpses, and Shen Yan'er, who has lost the protection of the iron bar, does not dare to continue to take risks.

"Blackie, let's push the cage outside first." Shen Yan'er, who had already figured out a countermeasure, calmly walked around the back of the iron cage, firmly grasped the iron bar with both hands, leaned forward, and used all her strength to push the iron cage outward.

As long as she can push the cage out of the bar, and then re-lock the bars with the chains she just used to do so, she can swing her sword and slash the lock without hesitation. No matter how many walking corpses are attracted, there are iron bars that will not hurt them.

This is the only viable option right now.

However, the cage itself is as heavy as a rock, and now there are two people locked up inside, so Shen Yan'er and Xiao Heifei only pushed the cage half a meter smaller. Luckily, the iron gate is not far from them, and they will be able to succeed if they spend a little more time.

When they reached the door, the bottom of the cage hit the walking corpse that had fallen to the ground, and the walking corpse had to be moved away in order to move on. Shen Yan'er didn't think much about it, and stepped forward to move the walking corpse. However, at this time, something happened that no one expected.

The walking corpse, which was obviously dead, suddenly jumped up and grabbed Shen Yan'er's neck!

pretended to be dead again, and the walking corpse repeated the old trick, but Shen Yan'er was still tricked.
