But behind the broken wall, there is a yurt-shaped hemispherical hall of thousands of square meters, in the corner of the edge of the hall, there are 5-6 huge circular arches evenly distributed, in the arches, if there is no demonic spirit floating, but also divided into red, yellow, blue, green and many other colors.

I'll go! What is this place? Don't... Under the Buddha statue, is it really a tomb tomb?

Mio and I got into the hole in the wall, and saw a corpse lying in the corner, dressed in clothes that seemed to be from the Republic of China period, the corpse did not decay, but the whole body was white and shrunken, like a skeleton, in the deep sunken eye sockets, the eyeballs stared straight ahead, and there were some shovels, pickaxes, axes and chisels and other utensils in the corner of the wall.

Liu Ruyun said: "This tomb robber died from the tomb tiger sucking blood, and there are two red spots on his neck. ”

I lowered my waist and saw that sure enough, there were indeed two small red spots on the neck of this thief's artery that were not easy to detect, and I couldn't help but feel a chill on my back, it has been almost 100 years since the Republic of China, and Biao Rong has been killing people and sucking blood since then, in fact, think about it, which of these old zombies has not practiced for nearly a thousand years, not to mention that Biao Rong has reached the realm of refining the gods and returning to the middle stage.

Looking around, there was only this one dead person, needless to say, the other accomplices were folded in these demonic holes.

"Miss Liu, is this really a tomb?" I asked, swallowing and foaming.

Liu Ruyun said: "It shouldn't be, I think... It's kind of like a dungeon. ”

"Dungeon?" I gasped.

Liu Ruyun nodded: "What do you think, what are pagodas generally for?" ”

"Pagoda?" I frowned and pouted, I really didn't have any research on this pagoda, and said in a deep voice: "Miss Liu, you say." ”

Liu Ruyun said: "The pagoda generally has two uses, first, to hold the relics of the Buddha, and second, to suppress the evil spirits, we just saw in the ninth floor of the pagoda, there is no vessel for the relics, and there is no relics, so... This tower should be a town demon tower! ”

"Demon Tower?"

"Not bad!"

"But......" I thought for a moment and said, "Since this sandbank city is the last castle of the Tangut people, and the pagoda was also built by the Tangut people to suppress their own princess?" That doesn't seem very logical, does it? ”

Liu Ruyun said: "The mystery needs to be revealed little by little, let's go to those holes to have a look first." ”

Mio and I walked to the center of the yurt hall and looked up at the dome, but we saw a small bright hole in the high ceiling, and I couldn't help but think...... This hole, could it be the neck of the severed head Buddha?

"Little brother, the corpse is gone!" Mio suddenly reminded.

I turned my head sharply, but when I saw the corpse lying in the corner of the wall, I don't know when it disappeared, my heart suddenly rose to my throat.

Don't... Was Biao Rong transported away? No sound at all, so fast! To my surprise, I saw that the hole in the wall when I came in was gone! Tools such as axes, chisels, shovels, etc., also evaporated out of thin air, and the surrounding area was exactly the same stone wall!

Oh, my God! Blindfolding, these things are invisible, I quickly walked to the position just now with my memory, kept kicking and sweeping with my feet, and did not touch the corpse, and the three tails also stroked the ground with their tails, empty as a wild, nothing!

I gasped, what a wicked nature!

"Little brother, look, above the entrance of the cave!" Mio reminded nervously.

I turned around and looked up, but I saw murals on the top of the huge holes, like phosphors!

The first thing that catches our eye is a fox with a lot of tails "wagging it", staring at us with cunning and ambiguous eyes.

"Oh my God! Silver fox! Mio exclaimed.

My heart is pounding, Silver Fox? Could it be that this Western Xia demon concubine is a fox spirit? So many tails, one, two, three, four, five...... I counted nervously until I reached seven! A total of seven tails, seven tails of silver foxes!

The Three Tails once said that the silver fox is an expert in playing illusions, could we... Are you all in a fantasy world? Although the seven-tailed silver fox can't be compared with the nine-tailed silver fox, the cultivation of the three-tailed gathering must be there, I swallowed nervously and spit, and my body subconsciously took a step back.

Not only is it a mural, but on the entrance of the surrounding cave, a series of weird and hideous monsters are also "depicted", including fierce and terrifying werewolves, frog-like monsters, nine-headed entwined giant snakes, and... The Dead Sea, which flooded many people and animals, the last painting was particularly weird, it turned out to be a swaying beautiful girl, like the flying sky on the Mogao Grottoes in Dunhuang!

My heart is pounding, the monster in the shape of a frog body, needless to say, must be a tomb tiger, I have seen Biao Rong's real body, the Dead Sea that is submerged by countless people and animals, it should be the black bug, the seven-tailed silver fox and the werewolf, and the nine-headed giant snake, all of which are beasts and demons, and the last beautiful girl dancing with a veil, is it... Is it the Western Xia Demon Princess?

Oh, my God! The owner of the cave seems to have pointed it out one by one!

I am endlessly confused in my heart, the three tails said, the silver fox method, is directly acting on the human brain, hallucinogenic from the inside out, this spirit beast likes to put people in a dangerous situation the most, let people kill themselves, we have been hallucinated by the silver fox, all the audio-visual is under its control.

Lost at the beginning, what's the point? What bad luck, how did you meet the silver fox here? Maybe at this moment, that Biao Rong is smiling at us incognito under the cover of the silver fox illusion.

"Miss Liu, do you have a way to crack the Silver Fox Illusion?" I asked sadly.

Liu Ruyun sighed: "The method of the silver fox cannot be cracked, but the human teacher can judge the good and evil through the hexagram, and the hexagram shows that we are not in danger for the time being." ”

With that, she emerged from the spatial ring and paced thoughtfully as she observed the hall.

Mio and I followed her closely, and I nervously looked around, afraid that the youkai depicted on the walls would emerge from some cave.

Three-tails was more careful, and simply wrapped her two tails around us, she was worried about the silver fox's illusion, and directly isolated us invisibly.

Liu Ruyun walked to the entrance of the cave of the dancing "Xixia Demon Concubine", and an amazing scene appeared, but when she saw that the fluorescent lines that depicted the image of the demon concubine, she suddenly changed and became the appearance of a tomb tiger, hideous and terrifying, barking at us with long teeth.

"Miss Liu, the mural has changed," I said nervously.

Liu Ruyun nodded, silent, and the three tails said: "Look at it, it turns out that the murals on the tomb tiger cave have become the demon concubines of Western Xia." ”

Liu Ruyun and I turned our heads, and sure enough, the murals on the two caves instantly swapped.

Liu Ruyun walked towards the cave where the tomb tiger pattern was originally painted, and just before she arrived, the mural of the demon concubine above the cave instantly reversed the mural of the wolf demon, and then, transposing, all the murals came to a big reshuffle, constantly changing directions, and my head was dizzy!

"It's just play!" I cursed angrily.

Liu Ruyun's face was calm, and she walked towards each cave one by one, every step she took, the murals above the cave were replaced irregularly, and she couldn't tell who was who? So much so that I suspect that these murals have nothing intrinsically connected to the caves below.

"Miss Liu, what can I do about this?" I said depressedly.

Liu Ruyun said with a determined expression: "Don't worry, let me calculate, we walked in all directions, twenty-three, thirty-four, twenty-eight, and thirty steps...... The number of graph transformations is as follows: tiger and man, wolf and snake, insect and tiger......"

She muttered to herself, my head exploded when I listened, what is this for? Hexadic sixth-order equations? Oh, my God! Can you count this too?

As the master of the Fish Sect, if the practice of the human teacher lies in calculus, then it is better to kill me, what I hated the most when I was in school was mathematics!

After a long time, Liu Ruyun walked towards a certain cave again, the murals on the wall changed again, she smiled slightly, pointed to the surrounding walls and said: "Clockwise, the tomb tiger, the demon concubine, the demon insect, the wolf demon, the seven-tailed fox, the hydra!" ”

I turned my head and looked at it in the order she instructed, oh my God! Corresponding one by one, Liu Ruyun closed her eyes slightly, and had already calculated the ..... on the cave in this hall The rules of the mural change are up!

This time, I was completely blown away! The human teacher is too terrifying! Liu Ruyun: Is that the human brain? Or a supercomputer? According to the steps of walking and the order of the pattern transformation, the rules of the pattern transformation on the wall can be calculated!

"Miss Liu! You... How did you do it when you broke the illusion of the silver fox? I looked at her in disbelief.

Liu Ruyun smiled slightly: "It's not broken, isn't the cave still shifting and transposing?" ”

"But... You've figured out the rules," I exclaimed.

Liu Ruyun nodded: "Not bad!" I use the "plum blossom easy technique" of the measurement method, plum blossom technique, a flower, a leaf, can be hexagrams, even sound, color, times, tone, this information can reveal the essence of things, although the silver fox's illusion is powerful, but people's wisdom is better, see if you are willing to use your brain. ”

My brain hurt again! What a lot of effort it takes! This man's teacher... It's really hard to be!

"Then, young lady, have you figured out the cave where the demon concubine is really hiding?" Mio asked excitedly.

Liu Ruyun nodded: "Yes, if the murals in this hall are not interchangeable, I really can't judge, but once there is a change, take the whole body, and everything can be traced back to the source."

Her words just fell, but I heard deep and heavy footsteps in a hole, and the ground trembled slightly, listening to this movement... It's like a crane smashing the ground!

Liu Ruyun frowned, quickly calculated, and said with a disgraced face: "Not good!" ”
