The key finally successfully inserted into the keyhole with unremitting efforts.

However, this is just the first step, and the next step is to rotate... Of course, this operation is not difficult. As long as you lie down and use the friction between the ground and the key to turn your body around the ground for a while.

And Bruce Wayne did.

Then, the lock was really opened!

“…”

Bruce Wayne felt the shedding of the restraint belt from behind, and he was confused. Not to mention whether his efforts for several hours had received rewards, just talk about this key...it was really the key to the restraint clothes he was wearing, which made him a little unbelievable.

In addition to being surprised, he had to think about why this key appeared here, who left it for himself... Is it a caregiver? Or the last person who was locked up here?

Well, let’s put these questions aside for the time being. In short, there must be someone who is helping him and he is helping him escape from here.

However, if you want to escape from this room, it is definitely not enough to just untie the bondage clothes. More importantly, you must open the door in front of you.

Bruce Wayne took off his cloak and walked to the door.

This is a very sturdy iron door, with the inner side wrapped with a buffer cotton layer like the wall. There is a small window that can be opened from the outside above and below the iron door. The upper window is used to observe the situation in the ward, and the lower window is used to deliver food to patients.

Such iron doors are obviously not a high-tech product, which means they should not be the type that can be opened by swiping a password or a pass card, but the most primitive ones locked with a "big lock".

Speaking of which, you may not believe that this type of door is the most difficult to open, because there is only one way to open it, that is, get the key, and the door lock is still outside, so in theory, it is absolutely impossible to open the door inside.

But it has already reached this point, so Bruce Wayne naturally cannot give up. Since someone is helping him, he cannot only help half of it. There must be a way to escape in this room.

So Wayne began to search.

This time, without the restrictions of the cloak, he could get more convenient access to higher places, so Wayne used his fastest speed to search every sponge around him.

Finally, he found a sponge above his head and seemed to be loose...

He stood on tiptoe and tore off the sponge!

Sure enough, there were a few lines of words written on the inside of the sponge.

[With the back to the door, at 2 o'clock, there is a vent. Every morning, you can smell the smell of cooking in the kitchen at 6 o'clock.]

Bruce Wayne immediately looked in that direction, and sure enough, near the corner of the ceiling, there was a place without a sponge, but a vent covered with small holes.

[Around 6:20, a nursing staff union came to check if you had excretion last night. If there was, he would take you to the cleaning room. If there was no, he would give you a breakfast.]

[There is a depression above the door. You can stand by the door beam]

[The caregiver looks very terrible, he looks like a shameless person]

[After going out, you can go to Ward 711 and find patient No. 09. He can help you if he is still there]

Behind this sentence, there is a large blank space without any writing. And at the end of this buffer layer, there is another sentence.

[If you find any useful information, please find a way to stay on it, we will always escape.]

【Good luck to us】

These handwritings are obviously different. Some are written in blood, while others seem to use leftover soup. In short, this sponge should be used by people locked up here to communicate...

So, in addition to myself, there should be many people here who have been imprisoned... Who are they? Have they all escaped?

Bruce Wayne didn't know, but he turned around and wrote down the blank space with the tip of the key, stained with the remaining oil stains on the plate...

[The fourth sponge next to the door contains the key to the binding clothes, but it takes a little time to aim it]

After he finished writing this passage, he suddenly felt that if he hadn't found the key, it seemed that he would not be able to reach the height of the sponge... But he was casual, so he stuffed the key into the original place and glued the sponge back to its original place.

After that, he sat quietly under the vent, resting while waiting for the smell of cooking to come.

After a while, a faint smell of oil smoke finally floated into Bruce Wayne's nose.

He opened his eyes suddenly, then pulled off the strap with the lock on the closure, wrapped it around his hand, and then stuffed the closure into the corner next to the door. After confirming that the clothes could not be seen from their "observation port", Wayne assisted and rushed to the top of the door, the sunken place.

Although this place is a gap, at best there is only space where one foot can be stuffed. Wayne can only hold on one foot and hang one foot in the air. He holds tightly above the door beam with his hands to let himself hang on the door.

According to Wayne's current physical strength, he started to feel sore in just two or three minutes, but... he just relied on his perseverance to persevere for twenty minutes.

Finally, at around 6:20, there was a sound of footsteps outside the door, and a little rhythmic humming sound.

That caregiver... is here.

Just a "click" sounded, and the observation port above the door was pulled open.

"On the 19th, yesterday...ah?!"

The nurse was about to ask, but she was stunned because there was no patient in the room.

"Damn... no..." the nurse shouted: "If this is lost, my open-air bath will be out of reach."

With this murmur, there was a rustling sound of keychains outside the door, and then... click... the door was opened.

Bruce Wayne saw the caregiver hurrying in from above the door.

At this moment, even if Wayne had been mentally prepared, he was shocked... because the caregiver's appearance was really scary. From above, he could see his red hairless head and a little hideous skin on his face. He looked like a severe burn patient.

But Bruce was not attentive to care about this now. He saw him jumping down without saying a word, and swinging the end with the lock in his hand round, just like a meteor hammer, and it was chiseled down the back of the caregiver's head.

Only a crisp sound of "dou" was heard.
