Zhang Xiaoyu was taken aback, and hurriedly fell back, but found that his hand was grabbed by the rotting corpse, so he hurriedly pointed at the head of the rotting corpse and punched it.

With a "bump", the carrion's long-haired head flew out and rolled to the ground with a "cluck", and the carrion that sat up from the bed fell immediately, and the hand that grabbed Zhang Xiaoyu's wrist also let go.

Zhang Xiaoyu breathed a sigh of relief, saying that just now, he was really scared enough, his punch was also out of self-defense instinct, I didn't expect the carrion corpse to be so unbeaten, and the head flew with a punch, just like a toy head that had just been installed.

It is said that Xia Xiaoxiao is covered with insects all over her body, and she is not dead yet...... Thinking of this, Zhang Xiaoyu couldn't help frowning slightly, could it be that the mutated virus would also make people mutate, right?

The sound of "bumping" from the corridor outside became denser and louder, and it seemed that the shell Lang would soon break into the door, and there was not much time left for Zhang Xiaoyu at this time, he had to act quickly, so he didn't dwell on this issue. He took the key and quickly ran to Ward 6.

When I opened Ward 6, I immediately came to my face with the smell of leprosy dogs.

Inside, there was a commotion and the sound of vicious dogs barking.

It seems that Xia Xiaoxiao's dog hasn't burped yet, which makes Zhang Xiaoyu vigilant, because the dog has mutated, and the mutation of the shell Lang is so bullish, let alone a dog?

When I entered the door, sure enough, a dog with stripped hair and sticky blood all over his body was shining in his eyes and looked at him viciously. Zhang Xiaoyu glanced at it, and thought to himself, this dog is probably going to change its name, it can't be called "Xiaoxiao", it should be called "big", or "stinky", because it is the size of a buffalo, and it still exudes a foul smell!

This skinless blood dog knew at a glance that it was difficult to deal with, if it weren't for a huge iron cage to trap this skinless blood dog, the current Zhang Xiaoyu would probably have been torn in half, half in the dog's mouth, and half under the dog's paws.

"Wang! Intimidate...... Barking!! When the skinless blood dog saw Zhang Xiaoyu coming in, he immediately half-squatted with two front paws, bared his teeth and grinned, looking like a vicious wolf, and was about to pounce.

Zhang Xiaoyu was stunned for a moment, he was hesitating in his heart, whether to search this room, to be honest, he was a little scared, the iron pillars of the iron cage were so thin, and they were all rusty, I don't know how long they could support it, if the skinless blood dog crashed out, then I am afraid that even if he was given a few more legs, he would not be able to escape.

At this time, the skinless blood dog suddenly kicked its hind legs, and it really flew over!

"Bump!!"

The head of the skinless blood dog smashed directly on the iron pillar of the cage, and then made a sound of "Zizi", and a foul-smelling smell of meat wafted over.

Zhang Xiaoyu couldn't help but breathe a sigh of relief when he saw this.

It turns out that the iron cage is connected to the power supply, as long as the skinless blood dog hits it, it will be electrified.

The skinless blood dog was so shocked that it screamed, and hurriedly took a few steps back, and finally looked like a dog and didn't dare to bark again.

But the big shell outside the corridor heard the noise here, and immediately became excited, and the sound of banging on the door became denser and louder.

Zhang Xiaoyu is a lot calmer now, since this skinless blood dog can't break through the iron cage, there is no threat to himself, so he can search with peace of mind.

Next to the iron cage in this room, there is a laboratory, Zhang Xiaoyu walked in, and then launched a carpet search, not letting go of any corner.

Such a purposeless search is actually very inefficient and thankless, but Zhang Xiaoyu has no choice, because after he entered the No. 6 ward, he didn't see any prompt information, well, maybe the skinless blood dog will have some information, but he didn't dare to approach it if he was given the courage of a sandbag.

Luckily, he soon found a bunch of keys with only two keys on them, one with a label "Ward 3" and the other with nothing.

Zhang Xiaoyu took the key and muttered to himself: "If I guess correctly, then, in each room, you can find a key to open another room, and then form the password for the door in the corridor in the order of opening the room...... If that's the case, then what is this unlabeled key for? ”

Then he looked at the iron cage where the skinless blood dog was kept, but found that the lock of the iron cage turned out to be a combination lock, that is, the key without a label was not used to open the door and release the dog...... So what is it for?

Zhang Xiaoyu thought for a few seconds, didn't figure it out, and didn't dwell on this issue, the most important thing at the moment is to find the password to open the door, and then slip away, now this situation no longer allows him to waste time on cranky thoughts, so he will temporarily hide the pimple in his heart.

He quickly left Ward 6 and went to open Ward 3.

Sure enough, in Ward 3, Zhang Xiaoyu searched for the key to Ward 4. This proves that Zhang Xiaoyu's previous conjecture was correct.

Then things went quite smoothly, in Ward 4, it took Zhang Xiaoyu less than two minutes to find the key to Ward 2, and then in Ward 2, he found the key to Ward 5.

Now, Zhang Xiaoyu has obtained the unlocking code: 163425.

In fact, after finding the key to ward 2 in ward 4, Zhang Xiaoyu had already found out the password, but he did not leave immediately, the reason is very simple, now he still has a key in his hand without a label, this key must be used for another purpose, and now he has not used it......

This kind of inconsequential and unclear meaning is for Zhang Xiaoyu...... Not digging three feet into the ground to find out is simply torture to him...... Especially now when there is plenty of time.

Right now, there is indeed a little more time to come out, because that shell lang has not yet broken the door, and judging by the size of the hole in the door, Zhang Xiaoyu has at least three minutes to use.

So, he decided to search both Wards 2 and 5 to find out what the key could open before leaving here.

Soon, Zhang Xiaoyu found the key to Ward 5 in Ward 2, and then opened Ward 5, and his efforts paid off, and finally he found a small box in the cabinet of Ward 5, which was not very heavy, but it was well sealed, and even the gap could not be seen, as if it was completely closed, and there was only one keyhole on it.

Zhang Xiaoyu inserted the key in his hand into the keyhole, twisted it a few times, and with a "click", the box opened.
