This kind of shallow groove that is not very deep is very much on the ground of this cave. Although the ground is hewn, it is not necessarily too flat.

Moreover, it is very dark here, and it is basically lit by our flashlights, and no one has paid attention to these ordinary uneven grooves or bumps under our feet.

Han Chang's carefulness allowed us to greatly save mental activities, and also let us get unexpected surprises.

I held the hexagonal box in both hands, carefully compared the lines in the groove, and found that this was exactly the pattern of the nine-wrong footwork. The Nine Wrong Footwork is a pattern of the mechanism, and the implied mechanism is very profound, and the pattern that is directly used as a key could not be more appropriate.

I flipped the hexagonal box over, found the symmetrical shape on the hexagonal box, and put it on. After that, I flicked my hands and told everyone to step back and wait and see how things changed.

"How do you feel like nothing has changed?" After being silent for a few seconds, Yu Qian couldn't help it.

"Such an old mechanism, it should take time to activate!" Zhou Jun guessed.

I nodded and didn't speak, but I agreed with Zhou Jun's guess.

It was a little while, about a minute. The hexagonal box remained the same, standing quietly in the groove, without the slightest change.

"Isn't that how it works? Why is it still not the same? Yu Qian was skeptical again.

I also wondered if it was an old thing, and it had been so long, so something had to happen. No matter how bad it is, there should be some sound. But now, that's too quiet, right?

"Will you have to twist or press? Don't you need to press and twist again to unlock the lock? There was silence for a few more moments, and everyone was a little impatient and even suspicious. But at this time, it was still Han Chang, and she suddenly proposed.

We were all stunned for a moment, and then we saw Zhao Zhifeng walking straight over, bending down, holding the hexagonal box with both hands, and then pressing down.

There was a "click" sound of the machine spring popping up and suddenly came from under the groove.

Zhao Zhifeng, like us, all showed a look of surprise. Zhao Zhifeng was even more excited, and then tried to twist it.

But this time, his expression that was still excited froze suddenly, and he seemed to be unable to twist. And at this time, the sound of the machine spring also stopped!

"Try to the left!" Han Chang reminded again beside him.

Zhao Zhifeng looked at Han Chang, and then twisted again convincingly, this time in a different direction, and the force seemed to be appropriate, the hexagonal box turned out to be exactly as expected, twisted 60 degrees.

The sound of the machine spring sounded again, and it was connected in a string, crackling through the cave.

"Why hasn't it changed?" After listening to the sound for a while, Yu Qian asked again. It's no wonder that the spring rang for a long time, and the tomb door didn't seem to be open.

"What's going on? Could it be that the mechanism is broken? Zhao Zhifeng was also puzzled, looking at the hexagonal box a little confused.

"It's not bad! It's not done yet! Get out of the way, I'll come! After pondering for a while, I thought of some possibilities, so I walked over and said very politely to Zhao Zhifeng.

Zhao Zhifeng hurriedly gave up his position, retreated to Han Chang's side, and watched my operation. At this time, I also remembered that among the mechanism techniques included in the Nine Wrong Steps, there is a kind of lock spring technique called the six-party joint lock. There are six different types of mechanical locking techniques, but although the six are different, there is a kind of joint locking technique in series, combining the six locking techniques together, and producing a mutual chain effect.

Therefore, this lock technique is very strong and very difficult to solve. If there is no correct way to unlock the lock, then there is only one way to break it, which is the strong destruction type. However, this is also the biggest fame. One of the most powerful features of the Six-Party Joint Mechanism is Honkai.

The Six-Party Joint Mechanism is very large, and is usually built underneath something that needs to be locked. This means that if you want to break through this trap strongly, you have to dig underneath. If you go down to the bottom, you can imagine the impact, and the things locked on top may collapse, be damaged, and everything will return to dust.

And if you forcefully break through the triggering device of the Hexagonal Combination, which is the groove keyhole, this will trigger the locking mechanism of the Conjunction Technique. The joint mechanism will be completely ineffective, and the six locks will fight separately, and even lock and lock the door completely.

Therefore, the Night King warned in his last words, don't try to open this tomb by other means, otherwise you will lock it up, and never want to open it!

Therefore, if you want to open the tomb door, you must use the key in the right way! I'm afraid this is what the Night King said, and it will be correct at a glance. The Night King only gives opportunities to those who understand the Yin and Yang Diagram, and he seems to absolutely trust the character of those who understand the diagram.

Of course, it is also possible that he has a good impression of life that also understands the picture, and thinks that he will be a person in the same way, with common characteristics, and a person of the same kind. And people of the same kind will definitely help him fulfill his wish.

No matter what kind of it is, if you want to open this tomb anyway, you must fulfill the Night King's wish, which is inevitable!

I took a deep breath, looked at the hexagonal box, and finally reached out. Although I haven't practiced this six-party joint mechanism, I have also understood it, and if you unravel it step by step, you should still be able to do it!

Unlock the first step, press down, and the second step, twist right. The third step is to press down, I pressed the hexagonal box down again with a slight force.

"Click!" This time, a loud spring sounded, and it seemed that the hexagonal box had reached some shrapnel or something, triggering the shrapnel.

For a moment after the sound, the groove that had completely submerged the hexagonal box suddenly spun around, and then a patterned section popped up around it.

This is the fourth step, rotate the hexagonal box, corresponding to the section with the pattern, and press it sideways!

In this step, the test is the familiarity with the graph. Because the hexagonal box is completely sunk in the groove, you can't see the pattern next to it, so it is very difficult to rotate to the same pattern as the side section.

But this does not bother me, I really feel that it is easier to remember this picture than to remember my own name.

Rotate two faces to the right, and that's the diagram. Then, with a strong push, the side was completely closed. The hexagonal box and the side plate suddenly fit tightly, and there was no gap at all.

"Click......" was another two bounce sounds, and the groove began to rotate with the hexagonal box, which was a very mechanical hard rotation, one at a time.

Actually, this is the process of unlocking, just like a ratchet, it is falling one by one.

After a few seconds, the groove makes a quick turn and a half, and then quickly turns back. That is to say, a lock has been unlocked.

After a few turns, cracks suddenly opened around the groove, and before we could react, those gaps suddenly protruded into a stone platform, and grew rapidly, reaching close to our waist with a hexagonal box.

This is a workbench!

A few of us looked at each other, who would have thought that such a sophisticated technique was the product of thousands of years ago? No matter how you look at it, it looks like a science fiction movie!

I, Zhou Jun and Yu Qian are almost numb, especially me and Yu Qian, who are extremely familiar with this kind of exquisite trick, and they are no longer surprised. Zhao Zhifeng and Han Chang, who had never seen each other a few times, looked at the stone platform with their mouths wide open, and looked at the stone platform with a ghostly look, and their bodies seemed to stiffen.

I smiled, walked over to the stone platform, and began to operate the fifth step. This fifth step has nothing to do with the hexagonal box, this step is on the stone platform.

Directly in front of the stone platform, that is, on the side facing the tomb door, that is the lock, the base point of this mechanism. This has nothing to do with the direction of the tomb door, but only with the yin-yang diagram. If you don't understand the diagram, you may not know which side is the lock. After all, this lock is the same as the other four sides, it is a smooth stone wall, and there is no difference.

But why are there four faces and not three faces? The square cylinder is four-faced, right? That being said, don't forget that there is also a face on the top side, which is the one with the grooves. The top side may also be locked, as long as the diagram of this six-party joint mechanism is in this direction, it will cause the lock to be on top.

The fifth step is to find the lock position, which is equivalent to staring at it and working in vain. However, if you can take four steps, it is impossible that you will not be able to take the fifth step.

The fifth step is like the evil tomb opening the tomb entrance and the fourteenth number returning to hide and closing the array eye, which is a puzzle.

But where did the picture of the smooth stone pillar come from? That's the key! This picture is drawn! Whatever you want, it's OK to outline the key lines on the tomb door on this stone wall.

Of course, this line must be symmetrical with the tomb door, and occupy the full width of the pillar face. Otherwise, the unlocking requirements will not be met.

When I first came into contact with this technique, I thought that I had to draw it in proportion and with one stroke. However, after further research, I realized that the full occupation of the required part of this step is the key.

Full occupation, in fact, means that the corners must be drawn in place, and the line pattern must be drawn on the four edges of the stone pillar surface. The real meaning of this is that the real position of the mechanism is actually in the position of the four edges.

Drawing lines in turn is actually to press the activation mechanism of these points in turn, and find the corresponding position.

Therefore, this step is a test of the key lines to find the picture! In this large diagram, the key line pattern is a coherent line, so which one is so many lines?

Anyone who knows a little bit about the diagram will not know, only the old fritters who have been completely immersed in it for many years will move. I'm just so, I have nothing to do, and I've been playing the old fritters for many years in class. This thing can be seen at a glance.

And I don't draw this line, only a fool does. What's more, I don't want to squat on the ground and carve a dagger against the stone wall like a child.

The lines are familiar, where to start, where to turn, where to end, clearly. The agency also knows it, and the actual meaning is also understood. In that case, why don't I just press the mechanism?

Holding the dagger in my hand, with the handle of the dagger, I struck sixteen positions in the four corners in turn, and this is the correct way to open the fifth step.
