I only heard a soft sound of "pop", and before I could see what was inside the iron box, a black gas came out first.

Tang Yan's face changed greatly, almost like an electric shock, and the small red flower above the iron box immediately rushed down, the black gas was suddenly covered by white light, and several impulses could not come out, after a while, I saw that the black gas gradually shrank, and the jade-like white flower gradually turned black, and actually sucked this black gas in.

It wasn't until the black qi completely dissipated that Tang Yan waited for a while before coming over, she looked intently at her little flower, her father had worked so hard to refine the strange treasure "Hell Snow Lotus" for her, at this moment, the original ruby-like petals had completely turned purple and black, and it looked a little hideous.

Tang Yan's face changed slightly, and he said in a low voice: "Dragon corpse poison!"

She cursed under her breath as she turned her gaze to the tin box.

It was very simple, and there was only one thing in a small tin box: a golden-green, intact jade slip.

Tang Yan was stunned for a moment, she didn't expect that there was such a rare and highly poisonous thing as "Dragon Corpse Poison" in this iron box, but she was just guarding such a small bell, she looked left and right, and didn't see anything strange, she groaned for a while, and slowly stretched out her hand to pick up this jade slip.

"Dangchang!"

A crisp sound, as if echoing in people's hearts, resounded in this secret stone room that had been quiet for eight hundred years.

Tang Yan picked up this jade sword, but seeing that the jade was delicate and delicate, she touched it lightly and made a sound again.

There was no text on the jade slip, but for some reason, there seemed to be an inexplicable note in the crisp voice, telling a thick ancient book.

Tang Yan saw it in her eyes, she liked it very much, and the disappointment just now was also diluted a lot, and she checked it carefully at the moment, and there was indeed nothing strange, it seemed to be an ordinary exquisitely made jade slip.

Tang Yan thought about it like this, so she made up her mind, but seeing that this jade slip became more and more fond of it, she tied it around her waist, turned her body, and sure enough, there was a burst of crisp bell sounds, which was extremely pleasant, Tang Yan was very proud, and nodded again and again.

Then she scrutinized the stone chamber again, but found nothing, and even the pile of rubbish she had inspected, and there was nothing of note, let alone any way out.

After finishing her work, Tang Yan slowly stood up, it was time to go and see the situation on that stupid boy's side.

Before walking out of the stone room, she took one last look back, only to see that the stone room was still in chaos, and the pile of garbage was even more chaotic after she turned it over, all kinds of weapons were thrown to the ground, and the big axe was also thrown in the corner of the wall at random.

Then, she walked out of the stone chamber.

The tunnel on the left hand side that Xu Chen entered just now was much longer than the road on the right hand side that Tang Yan entered, Tang Yan walked for a while before seeing the light light on, but the situation inside was still not clear, but for some reason there was no movement inside, she had a faint worry in her heart, there are a lot of strange and cruel things in this Modun, weird and unpredictable, will it ......

She subconsciously quickened her pace, walked into the stone room, took a closer look, and then relieved herself, only to see Xu Chen standing in the stone room, looking at the stone wall, stunned. Tang Yan breathed a sigh of relief, and then carefully observed this stone room, only to see that this stone room was much larger than the stone room she had just arrived, but it was empty, and there was nothing. But on the hard stone wall of the stone room, there were dense stone carvings, and Xu Chen was frowning at the moment, and it was these things that Xu Chen was looking at.

Tang Yan frowned, walked forward, looked at it, and showed joy on his face, only to see that at the beginning of this stone carving, there were only four big characters engraved.

Devil's Book of Heaven!

"Book from heaven, this is book from heaven!" Tang Yan couldn't help but cheer.

Xu Chen's body was shocked, and then he realized that Tang Yan had come to his side, but his attention seemed to be only on her words: "Book of Heaven, do you know what this Book of Heaven is?"

Tang Yan glared at him and said, "How could I not know that this 'Demon Domain Heavenly Book' is the Demon Sect's holy scripture, and from ancient times to the present, all the Holy Sect disciples' supernatural powers and laws have been comprehended from this heavenly book. ”

Xu Chen's body was shocked again, his face was confused, he turned his head to stare at the stone carvings on the wall, and after a while, he said in a low voice: "How is it possible?"

Xu Chen seemed to be unaware, and his eyes only looked at the words engraved on the wall.

Actually, to say that it is words, but it is just like words, just like what you have seen on the cave wall before, you know that it is words, but you don't know it at all.

Tang Yan snorted, she wanted to be angry, but after thinking about it, she didn't say anything, she also looked at the wall, and after only a few words, she only felt dizzy, and she also admired Xu Chen, he could actually read such a dry text.

But when he turned his head to look at Xu Chen, he was slightly surprised, only to see that his face was full of pain and confusion, and the whole person was trembling slightly, and he couldn't say anything.

In fact, if you change to anyone in the world, I am afraid that Xu Chen's mood at this time is not excited. This "Demon Domain Heavenly Book", known as the classic of the Demon Sect, was born out of nowhere, and he didn't know it at all, but he could feel the bewitchment during the period.

"You know?"

Tang Yan slowly came to Xu Chen's side, looking at Xu Chen's surprised face incredulously, "Why can't I understand it?"

At this moment, the two of them unexpectedly saw an inconspicuous groove on the stone wall, which was the size of a bamboo slip.

At that moment, it was Tang Yan's turn to be surprised.

For some reason, Tang Yan walked uncontrollably to the groove, and her right hand actually stretched out to her waist.

The jade slip was slowly taken out, and the slender fingers trembled slightly and put the jade slip into the groove in the wall.

At that moment, a purple light suddenly struck, like a flash of light that had been cut off for thousands of years erupted wildly in an instant.

The next moment, the strange and ordinary words on the wall seemed to suddenly come to life, constantly swimming on the wall, and at that moment, Tang Yan seemed to understand the words on the wall.

From this text, she was shocked to find that it actually told the ins and outs of a small jade sword, and it was indeed in Xu Chen's hand.

There are also all kinds of magical powers in this Demon Sect, which are extreme and special, but above the root, it is in this "Demon Domain Heavenly Book".

changed to another person, such as Tang Yan, naturally he didn't have any thoughts after reading these words, but who could understand the surprise in Xu Chen's heart?

A thought that had never been there lingered around Xu Chen.

He looked at it involuntarily, his face pale, his heart stirred, with fanaticism and strange curiosity and hunger, faintly feeling that a big secret was in front of his eyes, but he could not touch it, he could not see it, but he was even more attracted to himself, and ran towards that purpose.

It's just that in his heart, there is also a little fear, is this what it should be?

Tang Yan looked at Xu Chen for a long time, and saw that he was still engrossed in looking at the stone carvings on the wall, with a strange expression, as if he had completely forgotten that he was standing next to him, and he was annoyed for no reason, and snorted coldly, but Xu Chen turned a deaf ear and did not make any movement.

The corners of Tang Yan's mouth twitched, she was very annoyed, but somehow she didn't want to teach this person a lesson, she turned around and walked out with hatred, and stepped out vigorously when she left, but unfortunately the stupid boy still didn't react at all.

Tang Yan angrily walked out of the stone room, returned to the stalactite cave, and sulked at the skeleton, it was nothing to think about, but it was not pleasing to the eye when he saw that kid, the more he thought about it, the more angry he became, and then he saw that the originally beautiful "Hell Blood Lotus" in his hand was now black, and he immediately transferred his anger to the black-hearted old man.

She pointed at the skeleton and said angrily: "You dead old ghost, after 800 years of death, you will still harm people and me, and my lotus flower will become ...... Become ......"

Unable to continue a sentence, Tang Yan's liver fire became bigger and bigger, not to mention that, with a wave of his robe, the "Hell Blood Lotus" flew out and turned around on the skeleton and came back, and after a while, only the sound of cracking bones sounded, and at the sound of "Titica", the skeleton actually fell in pieces.

After making a move, Tang Yan's anger eased a little, and he couldn't help but feel a little regretful in his heart, he didn't know where he got so angry, but when he looked at it in a blink of an eye, he was taken aback, it turned out that there were still a few lines of words on the stone wall that was covered by the skeleton just now, and he hurriedly walked over to take a closer look.

The Tao is the devil, the Buddha is the devil, and everything comes from one mind.
