There was no key socket or anything like that on the iron door, except for the palm print in the middle.

Hong Bingying held the candle and looked up and down the left, left, right, and right up and down the iron door, but still didn't find any kind of mechanism somewhere, if it wasn't for the people involved, the ability to hide the mechanism was really good, then there was no mechanism here at all.

Focusing on the palm print in the middle of the iron door again, Miss Hong Bingying hesitated a little.

He always felt that the palm print on the door was tempting the people who saw it to put their hands on it. Hong Bingying didn't know what would happen if she really put her hand on it. It doesn't look like this rusty iron door will be swallowed by future people.

Gritting her teeth, Hong Bingying stretched out her hand and put her left hand on the palm print in the center of the door.

"Shhh

Hong Bingying felt a pain in her hand, and hurriedly retracted her hand, and when she looked at it again, a small wound appeared on the position of her index finger, the wound was only the size of a needle, and a drop of red blood oozed out of the wound, like a red gem in the flickering light of the candle.

"It's unlucky, I knew there was something wrong with this handprint on the door. ”

Hong Bingying muttered, put the injured index finger into her mouth, felt the sweetness in it, and thought in her heart: If you are stabbed, you won't be poisoned, right?

Just thinking like this, there was a creaking sound from the iron door in front of him, and before Hong Bingying could figure out what the situation was, the iron door slowly slid open to the side, revealing the deep darkness behind the iron door.

Hong Bingying waited for a long time, and did not wait for the rest of the front door, so she had to carefully grab the candle that was only half of it, and poked her head out of the open half of the iron door.

"Anyone?"

Behind the door is a large space, even if Hong Bingying grabs the candle, it only illuminates the space within a meter or two nearby, and the overlapping black shadows in the distance are not real, Hong Bingying opened her mouth to ask, but she didn't expect to get any response.

Sure enough, after asking, Hong Bingying waited for a long time, and there was no sound in the room, so Hong Bingying held half a candle in her hand and boldly walked into this space that sank in the dark.

Approaching with a candle, Hong Bingying realized that the overlapping black shadows that were originally hidden in the darkness turned out to be rows of bookshelves. All the books placed on the shelves, there is no text on the spine, and it is the case that she has read more than a dozen books in a row, Hong Bingying took one down casually, but she also did not see any text on the cover, and when she opened it, Hong Bingying didn't know any of the words in the book, it was a kind of text that was as crooked as a tadpole, which made people look at it and felt a little uncomfortable.

Hong Bingying walked forward cautiously, whether it was on the ground or on the shelves, and even on the books neatly placed on the shelves, there was dust accumulation, and it seemed that no one had ever cleaned here, not only that, but in this room full of bookshelves, even the windows were only the size of a palm, and only a faint moonlight shone in from the outside, leaving diamond-shaped spots of light on the dusty ground.

Bypassing all the bookshelves, Hong Bingying saw a door at the end of the passage, and when she got closer, Hong Bingying found that it was actually a heavy iron door, with no keyhole, and there was no palm print in the middle of the iron door as before, and she didn't even know if it was because of the closed surrounding environment, there was not even a trace of rust on the iron door.

Luckily, the iron door was not closed, but left a gap for one person to enter and exit, as if it had been deliberately placed to lure in the closer.

Therefore, Hong Bingying walked straight in.

The candle in his hand was only half broken, and he didn't know when it would burn out, and if he didn't find something before the candle burned out, then he would have to wait until tomorrow to come back, or simply give up the possibility of finding something here.

Under the light of the candles, Hong Bingying clearly saw that there was a futon in the middle of the room, and the golden futon had been placed here for I don't know how long it had been placed, and even the silk threads on it had cracked to varying degrees, revealing the white cotton wool inside. Shaking her head, Hong Bingying crossed the futon and continued to walk behind.

On the other side, near the wall, is a small cabinet, through the criss-crossing thin bamboo strips, you can see that the cabinet is full of ceramic bottles of various colors, there are no notes indicating the purpose or composition of the bottles, and even a few are crooked to the side, and the cork on the mouth of the bottle is missing.

Hong Bingying also took out a few porcelain bottles and shook them, but found that there was nothing inside.

On the other side of the wall, there is still a whole bookshelf, the books on the bookshelf are no different from those outside, there is no handwriting on the spine and cover, Hong Bingying took out a book and opened it, but found that most of the books were blank, and there was no handwriting.

Finally, Hong Bingying turned her head to look in the direction of the exit and found that there was a picture scroll hanging there, on which was a young girl, the girl did not look big, but she had a special charm blooming from it.

Sighing, Hong Bingying was a little disappointed and planned to leave, there was nothing worth caring about in this room, of course, it was impossible to have a clue about his mother, if this was really a library, what else could he find from these royal secrets, but unfortunately there were many books here, but Hong Bingying didn't know any of the words on the book, which made him feel a sense of loss that he couldn't steal into Baoshan.

At this time, a black shadow passed through the iron door that opened a crack, Hong Bingying's eyes widened, and she used all her strength to not let herself scream.

"Hehehe, it seems that there is a very bold junior......"

An old voice came from the direction of the black shadow, but Hong Bingying breathed a sigh of relief, reached out and grabbed the long needle hidden in her clothes, as long as it was not a ghost, dealing with an old man was still no problem for Hong Bingying.

It wasn't until the dark shadow of the speaker came within range of the candle that the Red Soldier could see his appearance clearly.

The old man had white hair, wearing a black loose robe, crisscrossing wrinkles all over his face, but a pair of eyes were not cloudy because of age, but bright as stars, he stared at Hong Bingying firmly, as if looking at a work of art.

"Who are you?" Hong Bingying took a step back, but bumped into the bookshelf behind her.

"Who am I? Hehehe, in fact, I also want to know this question, I have lived for too long, it seems that I am no longer the same me, in that world, I have encountered many things that you can't imagine, steel behemoths that rampant on the ground, or iron birds flying in the sky, and iron squid that can sink to the bottom of the sea, completely subverting my view of the world. The old man was a little excited when he first spoke, but when he said the latter, the old man seemed to become excited, and even his old face was a little more flushed.

Hong Bingying took another step back, but found that he had no way to retreat, he felt that the old man had gone crazy, maybe it was because he had been locked up here for too long. Looking around again, the cramped room looked like a prison cell.

Looking at the fear in Hong Bingying's eyes, the old man sat down on the futon in the middle: "You don't believe me, do you? Actually, before I saw those pictures, I didn't believe that there would be such a thing in this world, I once thought it was just my fantasy or a strange dream, but then I found out that it didn't seem to be the case." ”

After a pause, the old man continued: "Okay, those things will be talked about later, and then, as the only person who has been able to open this door for so many years, let me give you a small gift." ”

As he spoke, the old man put his hand into his clothes, took out a small seal from his arms, then put the seal on the palm of his hand, and stretched out his hand in the direction of Hong Bingying: "Come on, this is my gift to you." ”

Hong Bingying hurriedly shook her head: "I'm sorry, I didn't do anything, so I can't ask for your gift, and you haven't told me who you really are?"

The old man shook his head: "It doesn't matter who I am, besides, after such a long time, even if I say my own name, I'm afraid you won't know who I am, you just need to know that we are connected by the same bloodline, so I will definitely not harm you." And don't you really want this gift? You know, how many people in this world dream of it, but they can't get it at all, and don't even know that it's in my hands. ”

Speaking of this, the old man suddenly laughed: "Hehe, it seems that I am really old, and I feel ashamed to give a gift to such a mother-in-law." Come on!"

The seal was thrown by the old man casually and shot in the direction of Hong Bingying, who reflexively took it with her hand and just took the seal in her hand.

"The way to make it recognize the Lord is very simple, just smear it on the seal with your blood, then you study it slowly, I want to rest for a while, it's not good for people to get old, they always don't have the physical strength, and they don't have the energy they had when they were young. ”

After speaking, the old man closed his eyes, and the bright gaze of the connected stars was also hidden, leaving Hong Bingying, who had an inexplicable face, standing in place, holding an inexplicable seal in her hand, not knowing what to do.

What kind of thing like smearing blood on the seal, Hong Bingying would definitely not do it rashly, who knows if what the old man said is true or false, and he didn't even want to tell himself his name for a long time.

He forgot that the wound on his left hand had not yet healed, and a drop of hot blood oozed out and landed right on the seal.
