But what they have to do now is figure out how this thing works.

Because there is no similar pattern on the surrounding area of the iron plate, the walls of the cave on three sides are full of rough and rough pits where bamboo slips are placed.

"What should I do?" Xie Yuchen asked.

"Let's push it clockwise to see if we can make the disc spin faster." Wu Xiaoxiao said.

As soon as I got started, I found that it was easy to push in this way, but there was no machine expansion activation.

The two of them pushed it against each other again, and immediately felt the resistance, although it was difficult, but it was obvious that when the force was applied, there was a feeling of winding the chain.

The two of them glanced at each other, and at the same time increased their strength, blushing and their necks thick, and the iron plate finally turned in the opposite direction, and at the same time, there was a dull turning sound of iron chain gears rubbing below.

It's a pity that it hasn't been turned at 90 degrees, Wu Xiaoxie feels that he can't use his strength no matter what, and when he sees that the little flower on the other side is similar to him, the green tendons on his arms are tensed, but the iron plate doesn't move at all as if it is stuck.

Xie Yuchen gave up first, "We don't have enough strength, you have to get a cow."

Wu Xiaoxie was tired and collapsed, lying on the iron plate and being taken back clockwise, panting heavily, and slowing down for a long time before getting up.

Xie Yuchen was about to throw him a bottle of water, but his hand suddenly paused and asked, "What's that in your chest?"

Wu Xiaoxie looked down suspiciously, and when he looked at it, he found that there was suddenly a large piece of cinder pasted black on his chest, because the protective clothing was green, so it seemed very dirty, and then he saw that there was actually a big piece of cinder on his chest.

Wu Xiaoxie was stunned for a moment, immediately reacted, turned his head to look at the big iron plate, rubbed it on the back of his clean glove, and saw that the back of his hand had really turned black, and couldn't help frowning: "Why is this thing still painted?"

When I looked closely, I found that the black was mixed with many small particles, and when I rubbed my fingers, it turned into powder.

Wu Xiaoxie suddenly felt a little bad, and immediately used a dagger to scrape the nail cap in the groove of the pattern on the iron plate, and after crushing it, he walked to Xie Yuchen's side, put it on the ground, and asked him to unscrew the cap and pour water to flush it.

Although Xie Yuchen didn't know why, he still did it.

Soon, the black powder was soaked with water, and Wu Xiaoxie stirred it with a dagger again, turning it into a puddle of black and red slime.

"Take a closer look." Wu Xiaoxie dipped the tip of the dagger a little for Xie Yuchen to see.

Xie Yuchen frowned and glanced at it, his face immediately changed, "This is ...... Blood?"

"That's right, it's blood." Wu Xiaoxie nodded, "Someone has poured a lot of blood on the iron plate, and more than once."

"The layer of dried blood on it is very thick, and the lines on the iron plate are not patterns, but blood troughs." Wu Xiaoxie continued, "So, this is not an ordinary iron plate, but a sacrificial plate."

Xie Yuchen carried the water bottle and poured some on the iron plate, and sure enough, he saw that the water traces began to spread along the lines on it.

It seems to be alive, slowly flowing to the edge of the iron plate, and then it does not drip to the ground, but flows down the side of the iron plate to the bottom of the iron plate, and begins to flow towards the bottom of the pattern, gradually converging towards the axis. ….

Xie Yuchen was also a little surprised, and then smiled: "This thing was originally used like this, it seems that we really have to get a cow."

Wu Xiaoxie's expression was a little weird, "You say, is the blood on this a human blood? The people of Lao Jiumen shouldn't be so perverted."

When Xie Yuchen heard this, he was strangely silent, "I can't say."

Wu Xiaoxie grinned, "Then what should I do, I guess it's enough to let the two of us bleed, just our small physique, it's good that the two of us can have a cup together."

"Don't worry about your cow, the blood is too silky, why don't you try it with pig blood first." Wu Xiaoxie came up with an idea and said, "Pig blood is the most similar to human blood, I don't think this ancient machine expansion can be refined to the subtle difference of the type of blood."

Xie Yuchen nodded, "It's too troublesome to get blood, let's just get a pig up."

Wu Xiaoxie deeply agreed, and it was too exciting to directly make pig blood

In the face of those hairs, I don't know what uncontrollable situation will occur in the end, or the whole pig saves trouble, and it can also ensure that the blood does not coagulate.

But the question is, how to get the pigs in.

Wu Xiaoxie looked at Xie Yuchen, compared the arms of the two, and directly gave up the idea of carrying a pig.

At this moment, he misses the fat man who is physically responsible for the team, and the two guys who carry more than a hundred pounds of ancient knives on their backs and run faster than rabbits in the ancient tomb.

He clearly realized that without those three guys, the only advantage that could be reflected in him was that his brain was quite flexible.

In that case, he looked at Xie Yuchen and said, "We have to put a row of pitons on the roof of the cave in the passage, and use ropes and pulleys to bring the pigs in."

Xie Yuchen immediately agreed, the blood stains on his body before had dried up, and he didn't know if the effect would be reduced, so the two of them wiped the blood on their bodies again and came to the entrance of the cave.

Xie Yuchen used the walkie-talkie to notify the people below.

When the man heard that the owner was going to let them find a way to get a pig to hang up, he almost thought that there was something wrong with his ears.

After checking it several times, I bought a big pig from the nearest village with a question mark in my head.

Fortunately, some of the local guys have let pigs in the mountains before, and they know how to catch them, so that the pigs will be obedient and not run around, otherwise it is really not something that ordinary people can do if they want to transport a pig to the mountains.

While waiting for the pigs, Wu Xiaoxie and the two got most of the equipment outside the cave into the cave after getting the pitons and the transport device.

He also started to clean up the original blood stain on the sacrificial plate, and the lines on the iron plate became clearer, and it looked like the shape of an unknown flower, and there were traces of repair.

Wu Xiaoxie couldn't see what was going on for a while, so he took a picture with his camera, planning to pass it to Banai for the little brother and Muyu to see.

The next day, the background sound of a pig chirping came over the guy's walkie-talkie.

Wu Xiaoxie and the two also made a pulley set device on the edge of the cliff above.

The guys below were afraid that it would be difficult for the pig to struggle at a high place, so he temporarily numbed the pig with anesthetic, and then tied his limbs and hung up.

As soon as they arrived at the entrance of the cave, there was an unbearable stench on their faces, which made the two of them roll their eyes.

The two put on their gas masks again and carried the pigs into the cave as if they were cargo. ….

There was originally a stone hook on the roof of the cave directly above the iron plate, and the two of them hung the pig upside down.

The roof of the cave is not high, and when you hang it there, the pig's head is very close to the iron plate, and it can be driven directly.

Seeing that the pig rolled his eyes in a daze, Wu Xiaoxie's hand holding the short knife was raised and put down, and the knife was handed to Xie Yuchen's hand, "It's too bloody, I'm still a child, I can't do it, or you will come."

Xie Yuchen didn't answer, and took a step back with a smile, "It's better for you, this knife is very sharp, just rub it on your neck, and the blood will come out."

After the pig was hung up, the medicinal properties of the anesthetic gradually passed, and when I saw two guys sharpening knives standing on the side, I immediately howled in fright, and my voice was sharp and piercing, and I kept struggling.

Xie Yuchen pushed Wu Xiaoxie behind him, and laughed, "Let's fight quickly, Little Third Master."

Wu Xiaoye was furious, "You are so experienced, why don't you come?"

Xie Yuchen smiled gently, "I usually won't let the other party bleed when I move my hands, I'm not used to it."

As soon as Wu Xiaoye saw this guy's unquestioning expression, he knew that it was impossible to let this kid do it.

The pig screamed like killing a pig, Wu Xiaoxie stroked twice on its thick neck, a little broken, and said that it would be good if the fat man was here, but I don't know if he will kill his kind.

But the fat man likes braised pork so much, he shouldn't mind.

After a stalemate for a moment, Wu Xiaoxie still couldn't make a move, and asked, "Are there any guys below you who can kill pigs?"

Xie Yuchen snorted in disgust, "Why are you so good?"

Wu Xiaoxie said confidently: "The dignified little ninth master of the family, the person who is well-known in the Tao

I don't even dare to kill a pig, and you're not qualified to talk about me."

Xie Yuchen looked at him strangely, shook his head with a smile, and went out to inform the guys below.

Leave Wu Xiaoxie in the cave and face to face with the poor pig.

As soon as the people below heard the request, the guy who had driven the pig before volunteered to be hanged up.

The guy was a ruthless man, and without saying a word, he cut off a wine bottle, and after cutting off the bottom of the bottle, he cut a very sharp bevel on the mouth of the bottle, and stabbed it in the right place, and the red blood flowed down the bottle to the sacrificial plate, and countless blood marks began to crawl quickly on the pattern.

The pig howled for a few minutes, and as the blood drained, it had no strength to struggle any longer, and closed its eyes in a dying state.

After all the patterns on the sacrificial plate were covered with blood, after another three or four minutes, the originally rotating iron plate suddenly stuck, and a series of "click" iron chains rubbed and dragged sounded below.

Then, after a few muffled sounds, the sound of friction began to appear on the four walls of the cave.

Wu Xiaoxie and the others held the knife and looked around vigilantly, in case something suddenly happened, and suddenly the faces of the three of them became a little stunned.

On the walls of the cave in three directions, there was a sudden movement in the pit full of bamboo slips, and all the bamboo slips were pushed out of it, revealing strange protrusions, filling the cave wall into a complete wall.

Something protruding from the cave wall looks like part of some relief.

Wu Xiaoxie immediately took out the photo for comparison, carefully identified it, and found that the relief module in front of him had many similarities with the details on the photo, but it was obvious that the relief painting in front of him was more elaborate, but the key part of the stone wall was artificially knocked out. ….

Obviously, the iron plate in front of him is the mechanism that drives the relief on the three walls.

And the three holes in the photo, in order, seem to represent the hole behind him.

Carefully comparing the blood-stained iron plate with the photo, Wu Xiaoxie found the above problem at once.

At the intersection of the two largest patterns on the iron plate, there is a cross-cutting protrusion, but the position of this protrusion is different from the one in the photo.

He hurriedly told him what he had discovered.

Xie Yuchen frowned when he heard this, "It seems that the photo from Guangxi is a manual, it is showing us how to proceed next, if we take that bulge as a pointer and push the iron plate to the same position as the photo, it is likely to trigger the next mechanism."

Wu Xiaoxie nodded, "But we have already activated the mechanism once just now, and the iron plate can be rotated, so even if there is no photo, it is easy to deduce the location in the photo by pushing the iron disc indiscriminately, if this is some secret hint, it is too easy to be tested out, and there is no practical meaning."

Xie Yuchen agrees with him, "The reason why the password is called a password is because it is complex enough, no matter what this iron plate is, if it is combined with the surrounding reliefs, then there are only four possibilities for it to be tested, and anyone can try it."

"Have you ever heard of the law of contraction?" Seeing Wu Xiaoxie shaking his head, Xie Yuchen patiently explained, "When you don't have enough things to choose from, trying to ensure the effectiveness of one thing will reduce the number of times you choose."

"Like defusing a bomb." Xie Yuchen gave an example, "When you only have red, yellow, and green leads in front of you, then you may only be able to cut them once at most, because if you cut it wrong, it will explode."

After listening to this, Wu Xiaoxie looked at the four walls around him, then at the iron plate, and took a sharp breath, "You mean, if we want to turn this iron plate next, we will probably only have one chance!"

It suddenly occurred to him that the Nine Gates had suffered heavy losses here, and it was likely that they had tried and made mistakes, thus triggering an unimaginable nirvana.

The danger is not the hair that will be attracted to human blood outside, nor the group of corpse turtle kings inside the clay pot, but another layer that is difficult to understand in the eyes of the well-informed Lao Jiumen.

After all, their team was extremely large at the beginning, and there was no shortage of manpower and material resources, so they could completely use fire to burn off these hairs, or use special skills to transfer all these clay pots without alarming the corpse turtle king, as long as

Plenty of time.

Obviously, having the eaves and wall walking skills like Xiaohua is the basic skill of the Jiumen people to survive, so those things outside are not necessary for them to pay attention to, and they don't pay attention to them at all.

Xie Yuchen's tone was heavy, "Once we make a mistake and the mechanism is activated, we can't predict what will happen next, there has been more than one tragedy here, and we don't have the qualifications to easily try and make mistakes without full certainty and preparation."

Wu Xiaoxie looked at Xie Yuchen, whose expression was condensed in front of him, as if he had suddenly changed into a person, and was a little stunned, "Do you often solve problems in such a meticulous tone?"

"This is the standard for solving family affairs, and rigor is a family education engraved in the bones since childhood." Xie Yuchen looked at the iron plate full of blood with a faint expression.

Wu Xiaoxie suddenly thought that when he was a child, his grandfather had said that the ninth master of the old nine sects was the most thoughtful one in their group, as if he could see through the future one step in advance, and his style of acting was completely leaky, and he was incredibly cautious.
