"Madame, come and help me take a look. Di Mu stared at the eye on the book and beckoned Ruoyi over, "Do you remember this?"

"Isn't this the book you read a few months ago? I said this thing looks like an eye! What's wrong?" Ruoyi didn't understand why her husband would suddenly bring it up.

"Does Madame know where this book came from?"

"Origin, hasn't this book been kept in your study all the time?" was asked by Di Mu, Ruoyi felt even more confused.

"Alas, I don't have any other picture books in this study except the sword style, but the things in this book are not sword styles, how could I put such a book in the study?" Dimu felt irritated.

"What's wrong with you today, why are you suddenly bothered by the origin of an old book?" Ruoyi tried to figure out the situation.

"It's nothing, since Madame doesn't know the origin of the book, that's it. Dimu frowned and sighed.

"This book is so old, it must have been around for a long time. Ruoyi pushed the time forward, trying to remember if she had ever seen such a book, and sure enough, Ruoyi seemed to remember something. "I think I've seen this kind of picture book once, but that was years ago, and besides, it wasn't necessarily the book that I had seen in the first place. ”

"Madam, think about it again, is it such a book?" Di Mu suddenly saw hope, and opened the old book to Ruoyi, so that she could reminisce about it.

"It seems like it, but I'm not sure it's the book. Because too much time has passed, and her memory has long been blurred, Ruoyi is not sure if what she saw at that time was the book.

"Do you know where you saw this book, lady?"

"It was probably seven or eight years ago, when Xuan'er was still young, I remember that day Xuan'er went to the back mountain with Xiao'an to play, and then when I found them, the book was already in Xuan'er's hand. ”

"Call Xuan'er over. ”

"Where will Xuan'er remember, she was still very young at that time. ”

"Does that lady remember, when you found Xuan'er, where was Xuan'er at that time?"

"It's the back mountain, I didn't go far. Ruoyi recalled, "I was worried that they would go to Qingyan Lake to play in the water, but fortunately they were only at the entrance of the cave." ”

Qingyan Pond is a waterhole on the back mountain, in a cave, you can see this waterhole only a hundred steps into the cave. When you start to pick up water on the small bank, you will know about Qingyan Lake, and above Qingyan Lake is a hollow rock, and the sunlight can directly reach the water surface. Because Qingyan Lake flows with living water all year round, and it is clear and clean, the water used for cooking in the canteen is often picked up from here.

Eager to solve the mystery, Dimu immediately went to the cave in the back mountain, hoping to find some clues there. In the past, Dimu had never felt that there was anything worth seeing in this cave, but this time he entered it with the intention of solving the mystery, and he felt that every inch of the ground under his feet seemed mysterious, and the rocks on the sides and above his head were more likely to leave some clues or answers.

Dimu walked in small steps, observing the ground under his feet and the rock walls above his head and on both sides. Beneath your feet are gravel and debris and the droppings and claw marks of small animals such as rats, and there is nothing to notice about on a normal ground like this. The rock walls on both sides of the body and above the head are completely irregular, some like layers of waves, and some like some indescribable demeanor.

Dimu kept an eye on the shape of the rock faces, trying to discern something from them, but found nothing other than a few messy shapes and a few messy lines. Dimu tried to find something in shape from the messy lines, so he went in and out of the cavern, looking at it from all angles, but found nothing.

Puzzled, Di Mu walked to the side of Qingyan Pond, put his hands behind his back, looked at the sunlight pouring overhead, and then lowered his head and let out a long sigh: it seems that it is difficult for him to solve the mystery of that eye.

As if he had come here for nothing, Di Mu was a little disappointed at the pool in front of him. It was at this moment that he saw his own shadow reflected in the water, and where his shadow was hidden, the clear water reflected a rock wall carved with pictures. At this time, Dimu raised his head and looked directly above his reflection, and saw the small world sandwiched between two boulders.

Due to the obstruction of the boulder, Dimu could only see the traces carved on the small rock wall in the gap of half a foot, and as for what was depicted, he could not see it at all. If you climb up, no matter how small your body is, you won't be able to get in. At this time, Di Mu drew his sword, and he thought that with his practice of swordsmanship for so many years, it should not be a big problem to cut off the rocks that were blocked on both sides.

Dimu pulled out the sharp sword he had always carried with him, gathered all the strength of his body into his right arm, and slashed towards the rock above his head. With a sharp "poof", a deep sword groove was cut out of the rock overhead, and a puff of rock ash fell. The groove of the sword that was cut out was smooth and flat, which showed the speed of Dimu and the hardness of the texture of the sword.

Seeing the sword groove on the rock wall, Di Mu swung his sword again, and continued to slash down according to the sword groove.

"Boom!" With a dull loud thud, the sword fell, the dust kicked up, and the whole ground shook with it. As the boulder fell, Dimu looked up overhead, and most of the pictures on the rock walls were revealed, almost exactly like what he had seen in the old book. Finally finding a clue, and suppressing the excitement in his heart, Dimu then swung his sword and slashed down the rock on the other side, and the pattern on the entire rock wall was revealed before his eyes.

After looking closely, Dimu finally found the eye-like thing. Is this the kind of deadly thing? If so, how can we defend against it?" Dimu asked in his heart.

Judging from the traces carved on those rock faces, it was at least a hundred years ago, looking at the pictures that were blurred by the growth of the rocks, Di Mu calculated in his heart.

Looking through the pictures, Dimu saw a line of words on the rightmost rock wall, which was still recognizable when put together, although it had been deformed by the growth of the rock. Di Mu pieced together those comparisons one by one in his mind, and the line of words he came up with was: Chi Suzi, the one who invades but does not die, can practice blood arts.

Could it be that kind of deadly thing is Chisuzi? Invade but not die? Infected with Chisuzi, there is still a possibility of survival? Blood art? I have practiced swordsmanship for so many years, but I have never heard of blood art. I thought I could solve my doubts, but after seeing this line of words, Di Mu was even more puzzled. Although he was puzzled, in addition to his doubts, Di Mu's heart quietly ignited a yearning for Chisuzi and blood magic.
