The exit from the top floor of the hospital is a small room bulging from the roof, like a large closed chimney.

The two dogs stared intently at the big iron gate at the exit. It saw a faintly visible bloody handprint on the iron door, which stretched from the iron door to the back of the exit. It seems that he wants to lead the second dog somewhere.

Zhou Yan sat on the rooftop, he smoked for half an hour, and then patted his clothes and stood up.

He's rested enough.

"Dog, come here! Let's get out of here now! Zhou Yan stretched out a hand, he walked to the corner of the rooftop, measured the concrete floor under his feet with his eyes, he took a breath, and then lifted the evil eye knife in his hand and slashed it. The knife slashed at the concrete like tofu, cutting a corner of the concrete floor.

This hospital is definitely a tofu scum project. Zhou Yan didn't expect that foreign countries also had tofu slag projects.

Dozens of pounds of cement fell from the air, flew out of nearly 100 meters, and then smashed on the ground with a bang and turned into powder.

"Has this knife also become sharper?" Zhou Yan raised the Evil Eye Knife in his hand, and he saw that there was a strange mycelium pattern on the blade of the Evil Eye Knife, and the mycelium pattern was like white silk on the orange flesh, spreading from the bottom of the blade to the tip.

It was now as strong as the mycelium-covered iron door in the hospital.

There was a burst of cool air from the handle of the knife, and the cool air was transmitted to Zhou Yan's arm, spreading all over his body, making Zhou Yan shudder, and he saw that the red gem inlaid on the handle seemed to be a little different from before. Seven or eight mycelium spread from the perimeter of the handle to the gem. The handle of the Evil Eye Knife resembles a bloodshot eye, with red gems on the pupils, and the whites of the eyes on the hilt, and bloodshot on those green mycelium.

"This knife is worthy of being given by the system, and it is really easy to use!" Zhou Yan stretched out his index finger and touched the blade with some care, the blade shone in the sunlight, "If you can take it away, how nice it would be......"

In two minutes, Zhou Yan cut a one-meter-square pit under his feet. Zhou Yan used the sharp evil eye knife as a shovel, and he kept digging down, and soon dug a vertical passage from the corner of the rooftop. The hospital is 80 meters high, and according to Zhou Yan's speculation, it will take about three hours to dig from the roof to the ground.

In front of this sharp evil eye knife, the so-called situation of being trapped on the rooftop did not exist for Zhou Yan at all.

"Huang Shuen, what's the use of you engaging in this kind of thing with me?" Zhou Yan muttered to himself.

Thinking of Huang Huen taking away the rope, trapping him on it, and making the move of crossing the river and demolishing the bridge, although Zhou Yan said that it didn't matter, the more he thought about it, the more angry he became.

The second dog didn't come over for a long time.

Zhou Yan saw that Ergou hadn't come over, so he picked it up from the pit and shouted on the rooftop: "Dog, come here!" Woof! The rooftop was very large, and he was in a hurry and shouted out a dog language.

What about dogs? Zhou Yan was stunned, he turned around to dig a pit, why did the second dog disappear?

Ergou had already curiously followed the bloody handprints of the iron gate, and walked around the exit until he reached the rear. When he heard Zhou Yan's shout, Ergou's ears pricked up, and he turned at the same time, indicating that he heard Zhou Yan's words. But Ergou's body did not move for a long time.

There was a skeleton in a white lab coat, its withered finger bones that had exposed its bones, clutching a brown book that looked like a document.

The skeleton leaned against the wall and assumed a standard dead man pose.

"What is this? Is it OK to eat? When the second dog saw the brown bark, his eyes lit up. It opened its mouth and took the information in its mouth, and at the same time gnawed and gnawed.

"What are you doing? I've all screamed - wait, don't eat! Zhou Yan was taken aback when he saw Ergou nibbling on something that looked precious, and immediately snatched the bloodstained information from Ergou's mouth.

Dogs snatch food!

While retrieving the information from Ergou's mouth, Zhou Yan skillfully rewarded a chestnut on Ergou's head.

"Woohoo!"

Why are you so skilled? The second dog depressedly stretched out its front paws to hold its head, and it had another swollen bag on its forehead.

"Bloodstained information?" Zhou Yan originally wanted to train Ergou well and tell him not to eat what strangers gave him. But when he saw this piece of information that was almost chewed up by Ergou, he couldn't take his eyes off it.

On the cover of the leather book is a very strange line of text, which at first glance seems unusually profound.

"This—" Zhou Yan opened his mouth.

"It's ——! ——" Zhou Yan clenched the kraft booklet in his hand.

"What Chinese language is this!!" Zhou Yan let out a shout. His voice echoed across the rooftop, not subdued for a long time.

There was a violent vibration from the big iron door behind him, and those night demons who had fallen asleep again were all woken up by Zhou Yan. They angrily slammed the door to tell Zhou Yan not to disturb them from sleeping.

Soon the sound of the iron door stopped vibrating, and the night demons who slammed on the door suddenly realized that it was still daytime and they could not accept the sunlight, so they gave up slamming the door and returned to their lair.

It's not English, it's not Chinese, it's like a language created out of thin air. Zhou Yan opened the booklet and found that he couldn't understand the words inside.

These words are more like symbols formed by a dog smearing its hooves in ink on a piece of paper.

Calm down, be calm.

Zhou Yan's heart calmed down, he calmly read the words on the brown book again, and then came to a conclusion that he couldn't understand again.

"Still can't read ......"

Just when Zhou Yan was thinking like this in his heart, the words on the booklet in his hand suddenly changed. Rows of handwriting are pieced together crookedly, gradually forming the familiar Chinese characters of Zhou Yan.

After this brown book is obtained by different survivors, the language displayed on it will definitely be understood by the survivors.

Zhou Yan's heart breathed a sigh of relief, the props that can make the trial space control must be the key props in this trial space. There is no doubt that the brown book in his hand at this moment must have clues to the side quests.

"It's just, what's that weird language just now?" Zhou Yan muttered to himself, he still didn't understand. Before him, this skeleton was the only one who had access to this brown book.

Wrong! And one more!

Zhou Yan clapped his hands, he deserved to be smart, he glanced at Ergou, and then looked at the kraft book in his hand. Ergou also touched this kraft book.

"Can it recognize not only survivors, but also a dog?"

Zhou Yan laughed a few times and touched Ergou's head.

Before he realized that he had almost discovered the identity of Ergou. He never thought about the possibility that Ergou was actually a survivor.

Ergou tilted his head, it didn't understand why Zhou Yan was laughing.

Zhou Yan quickly finished reading all the contents of the brown leather book.

"Gain five survival points. Gain up to 20 survival points in a single trial space. A voice sounded in Zhou Yan and Ergou's minds at the same time.

Zhou Yan patted Ergou's back: "Good job!" Ergou, if it weren't for you, I would have almost missed these five survival points. ”

In addition to slaying the High Night Demon, this trial space also has a side quest. Although Dr. Huang, who had cheated Zhou Yan, had obtained the information of the trial space in advance and knew that this hospital was a key location, he still did not get any clues about the side quest.

It is also lucky, if it weren't for Huang Huen's rush to escape and cut off Zhou Yan's way out, he would definitely stay on the sunny rooftop and search for it, and the brown skin book in the skeleton's hand would definitely be found and taken away by him.

"There are still two nights left before leaving the trial space, a day and a half." Zhou Yan continued to dig the passage straight down, holding a second dog on his lap.

Although he was infected, he was out of danger.

After leaving the hospital, he only needs to hide well and wait until the time is up, so that he can return to the survival space safely, and the infection on his body will also be purified by the trial light orb.

According to the description in the leather book, he may see a beautiful scenery that he will never see in his life in the last moment of returning to the survival space.

"Wang~"

That's a lot of money.

Ergou's voice trembled. It has a severe fear of heights. Every time Ergou looked down at the downstairs, the height of nearly 100 meters directly frightened Ergou so much that he hugged Zhou Yan's thighs tightly. That's why Ergou is reluctant to go near the edge of the rooftop.

"Don't hug my legs!" Zhou Yan saw Ergou hugging his thighs and looking trembling, and he felt a little funny in his heart.

In the face of the dead silence of the city, the atmosphere of despair and the indifference of the heart, this silly dog can always bring joy and surprise to Zhou Yan.
