A not-so-good feeling hit Su Yu's heart, and she looked into the depths of the passage of the black hole.

The sound of shuffling and whimpering came intermittently, and it would not have been easy to hear if it weren't for the silence around and the amplification of the channel.

"Let's go up or ......," Zheng Wang said hesitantly.

Zhao Dacheng agreed: "Well, five students died, and this matter needs to be handled by the academy." ”

Su Yu looked at Hao Tian.

Hao Tian spread his hands: "I'm a waste now, I will go where you carry me." ”

Su Yu looked at Chen Yiqian again, but saw a different answer in his eyes.

She turned to the other three and said, "I think there's a big problem with this, maybe ...... It has something to do with Teacher Song's death. ”

It's hard not to think of these things one after another.

What's more, Su Yu looked into the depths of the pitch-black passage again.

The feeling is familiar.

This whimpering sound is also familiar.

"That's it," Chen Yiqian spoke, "The three of you go back from the entrance, as long as there is a signal, you will immediately contact the actual combat base, and I will go over with Su Yu to take a look." ”

But Zhao Dacheng denied this plan: "Then let's go together, and we will take care of anything we encounter." ”

"Yes, maybe it's not a zombie, if it's really a zombie, it's time to smell it and rush over." Hao Tian also comforted.

Zheng Wang raised the gun in front of him, and said boldly, "Then let's go, go and see what it is." ”

After reaching a consensus, the five began to walk deeper into the passage.

And the sound of rustling in the distance suddenly disappeared.

At the time of the last expedition, the underpass had two small square chambers and a larger one.

When they arrived at the first small square room, they found some canned chocolates and brown paper wrappers.

"Sure enough, there are supplies." This discovery diluted Zheng Wang's nervousness, and he stuffed a few handfuls of chocolate into his backpack and peeled a piece for Hao Tian.

"If something like this happens, I don't know if the game can continue." Zhao Dacheng looked at Zheng Wang, who was filling cans again, and said, "Maybe we will sit in the canteen to eat again in the evening." You take less, it's too heavy. ”

Su Yu and Chen Yiqian didn't stay in this small square room for long, they were still worried about the sound that suddenly disappeared from the depths of the passage.

And when they walked into the second small square room, they didn't find anything unusual. It was almost empty except for a few more wooden chests.

Chen Yiqian walked over and opened the wooden boxes, and found that there were neatly stacked anesthetic warheads inside, and even found some arrow feathers in a long box.

"Senior Sister Su Yu, your arrows are almost used, come over and load a few." Chen Yiqian opened all the boxes: "Everyone also add more ammunition, I don't think the hunting competition will necessarily be over." ”

The entire academy has been preparing for the Hunting Contest for so long, and there is a live broadcast for the entire C plate, how many pairs of eyes are staring at them, the senior management of the academy will definitely take some measures to cover up, and will not stop the competition.

Su Yu's quiver was indeed half empty, she rubbed her eyebrows, relaxed her tense nerves a little, and walked over to take down the quiver behind her back to fill it up. Although these arrows were no more than the fifty original arrows of her night, something was better than nothing.

"I have so many bullets, and I don't necessarily have so many zombies for me to fight." Zheng Wang patted his full bullet bag and joked to everyone.

The other four were just about to laugh at the way his combat jacket was stuffed and bloated, when a terrifying voice suddenly sounded from the depths of the passage—

A sharp whistle suddenly sounded, and the echo in the passage was terrifying.

Su Yu was excited, picked up the quiver and ran in that direction.

The other four also jumped up instantly.

"This is ......," Zhao Dacheng's answer was about to come out.

"It's the kind of whistle that Su Yu said! A high-frequency whistle that can manipulate zombies! Hao Tian urged: "Hurry up, don't let her go on an adventure alone." ”

Chen Yiqian and Zheng Wang had already rushed out first, and Zhao Dacheng ran behind a little clumsily because he was carrying Hao Tian on his back.

They had all heard Su Yu tell the whole process of the Song Zaihu incident, and knew the existence of this high-frequency whistle that could drive zombies, but they had never really heard it.

can look at Su Yu's reaction, this incident is inseparable from Song Zaihu's death.

The sound of running footsteps resounded throughout the passage, and the reason why Su Yu instantly decided to run this way was because she knew the meaning of this long whistle.

This is the whistle to let the zombies attack.

Last time in the basement of the biological research center, when the whistle of this tone sounded, the zombie with the goat's eyes rushed towards her as if it had received an order.

So who is this zombie attacking right now? In addition to the five of them, there are other people in this tunnel?

Su Yu didn't have time to think about it, she held the bow with one hand, and the other hand was on the dagger at her waist, hoping that she could be in time.

In the largest square room, a bright yellow bulb barely illuminates the entire space with a faint glow.

Su Yu saw this glimmer of light when he ran closer, gradually slowed down, and walked towards that side with a light pace.

The other four were able to follow.

The whimpering and roaring gradually became clearer, and the "click" sound of the upper and lower teeth biting that belonged to the zombies was infinitely amplified.

Just as they walked into the square room, a sharp and desperate scream suddenly resounded throughout the square room.

It was the last breath a human could breathe out when they received a fatal blow.

They were still late.

Under the dim yellow light, a zombie was buried in a person's neck and gnawed frantically, the sound of flesh and blood biting and teeth grinding filled everyone's ears, making several people's hairs stand up in an instant.

Several people raised their guns almost at the same time, and Su Yu also put the arrow on the bow.

They opened fire at the same time.

The zombie had its back to Su Yu and them, and no one could accurately aim at the center of its eyebrows.

But whether or not they could really kill this zombie with one blow, all they thought was to hit it with bullets, hit it hard, so as to stop it from continuing to eat this human corpse and prevent it from making this disgusting sound.

The bullet hit the zombie's shoulder and back, and Su Yu's arrow also pierced its neck.

The zombie finally stopped, and the corpse in his hand fell to the ground with a "click".

It stiffly turned its neck and turned its head, a pair of goat-like rectangular pupils looking at Su Yu and them faintly.

"That's it!" Su Yu blurted out.

This is the zombie that killed the eyes of the goat in Song Jaihu!

The four of them instantly held the gun tighter, and even Hao Tian slipped off Zhao Dacheng's back and picked up the submachine gun.

But the shrill high-frequency whistle sounded again.

The zombies suddenly attacked.

It was fast, and even more difficult to see in the dim light, and the five men shot wildly at its figure.

At the same time, the human corpse at his feet suddenly moved.

It stood up from the ground in a very strange position......
