Although I had already guessed such a result, I was still startled when such a sentence really came out of Wang Feiyang's mouth, and I looked at Wang Feiyang with an extremely shocked look and said, "Brother Yang, you're not kidding? Are you really the reincarnation of the Seven Killing Demon Lords? One of the three protectors under the Yin Tianzi? ”

"From the moment I picked up this Seven Killing Demon Knife, there was a very familiar feeling in my mind, this magic knife has a sword spirit, and it calls me the Demon Lord!"

"Really?"

"Absolutely."

Wang Feiyang walked towards us step by step with the Seven Killing Demon Knife, and then walked in front of the dry bone, and then lightly tapped his forehead with his fingers, and in an instant, an inky halo spread from the bone's forehead, and then spread to his body along Wang Feiyang's fingers.

Wang Feiyang took a deep breath, and his face showed an extreme pleasure; "This is a Dao body left by the Seven Killing Demon Lords back then, and they have been waiting for me here for more than two thousand years."

The three of us looked at each other, and in such a shock, we didn't know what to say for a while.

Wang Feiyang turned his head to the knife marks on the wall, and continued: "Back then, the Seven Killing Demon Monarchs followed Yin Tianzi to fight hell, and finally Yin Tianzi was defeated and reincarnated, and the Seven Killing Demon Monarchs fled back here after being seriously injured, and finally he used his last life to carve the knife spectrum of the Seven Killing Demon Knife on this stone wall, and the page of the knife score that my master Yan Fei got in Bashu City before, someone observed some fur from here, and then put out a fake demon cave in Bashu City, and this is where the real demon cave is. ”

"Where did you get this information?" I asked the first time.

"The sword spirit of the Seven Killing Demon Blades told me." Wang Feiyang turned his head and smiled at me.

His smile made me shudder, and I suddenly remembered the spell spirit of the Demon Suppression Ruler in my hand, and for a while I was really afraid that the sword spirit of the Seven Killing Demon Knife would be the same as the spell spirit of the Demon Suppression Ruler, and it would control Wang Feiyang's mind.

Wang Feiyang seemed to see through my thoughts, and said: "Don't worry Wu Dao, your curse bone spell spirit, no one has been able to tame it since ancient times, even Zhuge Kongming back then, so until now, it is still unruly, and my sword spirit of the Seven Killing Demon Knife completely surrendered to the Seven Killing Demon Lord more than two thousand years ago, and it has been waiting for me here for more than two thousand years, and I can easily control it." ”

"Really?" I was skeptical, and I still had some drums in my heart, although Wang Feiyang said that he could control the sword spirit of the Seven Killing Demon Knife, but how did I feel that he seemed to be a different person now.

"Did the sword spirit of the Seven Killing Demon Knife tell you why the Seven Killing Demon Lord chose to build the Demon Cave here?" Sun Jiuli on the side asked.

"Because this section of the Great Wall was built by Meng Tian." The expression on Wang Feiyang's face became even more weird; "The Seven Killing Demon Lords are the reincarnation of Meng Tian."

"Meng Tian is reincarnated." My mind suddenly buzzed: "Doesn't that mean, Meng Tian, it's your previous life?" ”

"Wu Dao, you have too many questions, this is the same as your character, some are too indecisive."

Wang Feiyang glanced at me with some dissatisfaction, and then he looked at the knife marks on the wall again, and actually laughed unscrupulously, that laughter sounded very infiltrating, just like the laughter of those villains in film and television dramas.

I always felt a little strange in my heart, so I subconsciously walked towards Wang Feiyang, stretched out my hand to put it on his shoulder, so that he wouldn't be too excited, but the moment my fingers touched Wang Feiyang's shoulder, he suddenly turned around and glared at me, this look shocked me, and I subconsciously took a step back.

"Brother Yang." I called his name.

Wang Feiyang didn't answer, but turned his head and continued to stare at the murals on the wall, about ten minutes later, Wang Feiyang seemed to have an understanding from it, he suddenly lifted the Seven Killing Demon Knife in his hand, and slashed at the stone wall not far away with an extremely strange amplitude, and in an instant, an extremely powerful knife qi blasted towards the stone wall over there.

We only felt that the entire cave was shaking, and the stone wall that was hit by the sword qi on the other side cracked a hole more than a person high, and outside the cave entrance, there was a cold moonlight shining in.

All of us looked at the entrance of the cave over there, but we didn't expect that under the Great Wall, there was another world connected to this stone wall.

Wang Feiyang put away the Seven Killing Demon Knife in his hand, then looked at a few of us and said: "Outside, it is the foot of the top of Yin Mountain, and this was once the main battlefield where Meng Tian led the Qin Dynasty army to resist the Xiongnu army. “

Sun Jiuli and I glanced at each other, although we felt that Wang Feiyang's almost commanding tone made people feel a little uncomfortable, but we didn't pay too much attention to it, we both nodded, and walked along the hole to the outside.

After Sun Jiuli and I walked out, Sword Dance naturally followed behind me, while Wang Feiyang stopped observing the knife marks on the stone wall and walked towards the Seven Killing Demon Monarch's Dao Body.

As soon as the three of us walked out of the hole, there was a noise behind us, and when we turned our heads, we saw that a large piece of rubble suddenly rolled down on top of the hole, and soon the hole was completely sealed.

The three of us didn't think much about it, maybe Wang Feiyang was afraid that we would disturb him.

Walking out of this cave, what comes into view is a very wide open space, there is no vegetation in the clearing, all of them are bare, and in the case of opening the yin and yang eyes, you can see that above this open space, there are countless extremely rich yin qi, and those yin qi converge into countless black clouds floating in the air, giving people a feeling of covering the sky and the sun.

At the edge of the clearing, there stood a towering mountain, which, perhaps at night, looked all black, and at the top of the mountain, it was just level with the moon in the sky.

That mountain is the highest mountain in the entire Yin Mountain, and it is called the top of the Yin Mountain.

The three of us first looked at the high mountain for a while, and then looked at this clearing and became fascinated, and the sword dance on the side said for the first time: "Master, we didn't seem to have seen such a clearing on the Great Wall before?" ”

"This is an ancient battlefield." I replied, "Maybe it was because we were chased and killed by those corpse puppets just now and ran too fast, we didn't notice the existence of this area, and there is a strong yin aura above this clearing, so under normal circumstances, it is difficult to find this generation when you look down from the Great Wall." ”

"Let's all be careful, since there are Yinshan corpse puppets on the Great Wall, and this piece is the main battlefield of the Central Plains to resist the Hun Tartars, maybe there will be more terrifying things." Sun Jiuli on the side said.

"Well, just don't walk around here so as not to cause some unnecessary trouble." I should talk to Sun Jiu as soon as possible.

"I just don't know how long it will take Brother Wang Feiyang to comprehend the Seven Killing Demon Sword Spectrum." Sun Jiuli continued.

"I can't say for sure."

Wang Feiyang's trip to the Demon Cave this time can be regarded as an adventure, similar to the encounter I had when I fell into the Phoenix Cave on Thunder Mountain before, and it took me several months to come out of Thunder Mountain at that time, and I don't know how long Wang Feiyang will take this time.

"Don't worry about it for now, wait a while."

The three of us sat on the floor, and simply treated the wounds left by the previous treatment of the corpse golem, and then took a brief rest.

Maybe it was because I was so tired, I just felt like I just closed my eyes for a moment, and when I opened them, the sky was already dark.

And looking at the sky from this position, even during the day, this ancient battlefield is still shrouded in a layer of rich yin qi, that feeling is as if we are under the second layer of black clouds, the yin qi obscures the sunlight in the sky, although there is still sunlight penetrating from above, it is miserable and white, making people have a very cold feeling.

At this time, I can see the appearance of this ancient battlefield clearly, except for the large area of rubble, what remains is charred black soil, and occasionally, you can even see that there are some weathered dry bones hidden in this soil, like a mass grave.
