Professor Zhang and Tang Chunjiao were speechless, indeed, although there were many dangers since entering the underground palace, they were all within their comprehension, but the hall full of exercises was ......

Were the ancients really able to master the smelting technology that surpassed modern technology? What secrets did the ancient civilizations hide?

Captain Jiang shouted, "Professor, come and see this." ”

Professor Zhang stepped forward and found that there was a six-pointed star in the middle of the desktop that could be moved, but it required a lot of strength, the designer was obviously familiar with people's hearts, and others would only touch the wall and ceiling if they wanted to find a secret passage, who would pay attention to the stone table in the center, let alone spend a lot of effort to turn over the desktop.

Of course, there will be no tunnels under the stone table, but the table top turned up is engraved with a floor plan, and everyone stepped forward in high spirits, but Tang Chunjiao was disappointed when he saw it.

"It's not a broken formation diagram, it's just a reverse formation diagram, it's not complete,"

Mo Daonan asked, "What is the Broken Formation Diagram?"

Tashi kindly explained: "The Broken Array Diagram is a general map that shows the secret passages of all the organs, as long as you know how to do it, you can control the overall situation, while the Reverse Formation Diagram only marks the escape path to avoid danger, and you can only protect yourself." ”

"Oh, it's an escape guide. "Changsha Road.

"Well, we're too greedy, and that's enough to save us a lot of trouble. Professor Zhang studied it for a moment, nodded and said, "Well, I was right before, but the map shows that there is a shortcut to get out of the dungeon first." ”

Chang Sha said strangely: "Professor, this underground palace is all active, and I can't say if I can find any way to find it." ”

Tashi spoke: "Haha, Brother Changsha, you are wrong about this, think about where we are now." ”

Mo Dao smiled and said, "The central axis, why should I think of it." ”

Mao Jingqin, who had been silent, couldn't help but say this time: "Professor, this picture is not complete, only the way to leave the underground palace, do you want to leave this underground palace and then attack the central control room from the outside?"

Professor Zhang said: "Yes, the authorities are confused, it is really difficult to figure out the changes in the underground palace from the inside, and according to common sense, there should be a road similar to the central axis from the outside to the central control room." Xiaomao, what do you think?"

Mao Jingqin hesitated a little: "I have a hunch that there may be ...... outside the underground palace More dangerous. ”

Several leaders were silent at the same time, and finally Professor Zhang said: "Let's go out of the underground palace first, if there is danger in the central control room, we will give up this operation, and focus on saving the lives of the scientific expedition members." ”

Tang Chunjiao was the first to agree, she was extremely afraid of the legendary sixty-four hexagrams Qiankun reversal of the palace change, just relying on willpower to keep pressing, don't look at her breaking through the formation and leading the charge very bravely, that is just the psychological comfort that she needs to win, she deeply knows that the organs on the road are simply not worth mentioning compared to the underground palace itself, the organs cost lives at most, as long as the underground palace miscalculates and takes a wrong step, it may be trapped in it, this is the ultimate fear.

Captain Jiang said: "Even if we want to leave the underground palace, it seems that we still have a level to break through." ”

He pointed to the end of the passage, the last stone chamber on the supporting shaft.

....................................

Liu Zai walked in the dark stone road, here is a secret passage that can lead to the hinterland of the trial ground, at first glance it is not commonly used, there is not even a lamp, it is dark.

However, these are not problems for Liu Zheng, after all, he is no longer an ordinary person, all aspects of his senses are beyond the reach of ordinary creatures, and there are even shark-like electric senses and pervasive divine thoughts, and there is no dark fear at the human level.

In fact, there is another way from the residence of the head of the sect to the control room of the central organ of the sect, and then it will be much more convenient to take the rail car to it, but Liu Zai just doesn't want to be convenient, and this road seems to hide some little secrets that interest him.

The map in the study is very detailed about the route mechanism, but there are several places that are vague shaded areas, including the small vault behind the master's residence, the mysterious sect forbidden place, that is, the trial place to go later, and the mysterious stone room to which this road leads.

There was finally no road on the other side, and Liu Zai Shennian swept away and found that what was blocking the way was a huge stone door that was at least five zhang high and three zhang wide, and there was a mechanical clock hanging on the door, which should be a lock.

Liu Zai probed carefully with his divine thoughts, this is much more complicated than the gossip turntable outside the treasure house, countless gear-shaped turntables are combined, and the dense scale is pure Fuxi sixty-four hexagram in various directions, this form of mechanical lock seems to be called 'Peerless Lock', Liu Zai has seen a similar pattern in a book of alchemy academy masters.

This thing claims to be an alchemical version of the combination lock, and without a password to unlock it, it is about the same as digging through the walls of the Forbidden City with a plastic spoon.

However, Liu Zai was not ready to unravel it.

Both hands sent out the sword qi against the sky, the whole lock fell down, and then one hand pierced through the stone door on one side and suddenly exerted force, after turning into a dragon, Liu Zheng himself didn't know what level his strength had reached, only felt that there was nothing to stop him in the world, and there was a feeling of hating the sky and hating the ground, why should it be unlocked when entering a door?

In the indescribable sound of the stone crushing into dust, the stone door parted left and right, like a dying mouth being rudely broken, revealing the broken teeth that had been beaten.

It turned out that the stone gate was connected by a riveting structure, and it was three zhang thick, but it was this kind of stone gate that compromised with Liu Zai, an unreasonable monster, and the cracking sound seemed to sigh helplessly.

Liu Zai broke open the stone door, and Shi Shiran walked in.

Strength is so capricious.

After walking for a while, a fire lit up in front of him, leading to the end of the road, illuminating a bright light in front of him, but the light was not mixed with anything flowing all over the ground.

Liu Zai couldn't help but think to himself, there would be something hidden here.

Walking into the empty hall, an avenue led straight to his eyes, Liu Zai was full of emotion, he still underestimated the ambition of the eldest brother of the family.

This is an arsenal, an arsenal without swords, facing the gate is a row of more than 20 tiger head bear body bed crossbows, under the firelight, there is no sign of rust, it seems that it has been treated by a special process, each is two zhang long, a crossbow and ten arrows, each arrow is composed of eight spiral cone-headed small arrows, that is, a salvo eighty arrows, the most terrifying bead bed crossbow in history is the Ming Dynasty "Wubei Zhi" contained in the god arm bed Liancheng crossbow, can fire four or five arrows at the same time, compared with this is the gap between the water gun and the firearm.

Behind is a boxy chariot lined up in formation, it is also full of thorny steel thorns, the style is strange and has never appeared on the battlefield, based on Liu Zai's pastime and reading books to accumulate half-hung cold weapon war knowledge, it is estimated that it is used defensively, this shape structure is obviously countless chariots can be built into a rock-solid temporary barrier in a short time, disassembly and transfer seems to be quite convenient, what specific use he is not clear.

After crossing the avenue in the middle of the chariot array, passing by more than 100 chariots, the two sides became half-beasts and half-carts, like mechanical vehicles that look like oxen and not horses, with front wheels and hind legs, which can be pushed and walked, and automatic mechanism devices, like the legendary wooden oxen and horses.

Tsk tsk, this is even the means of transport have been thought of.

Liu Zai pinched a cold sweat for Boss Cao in his heart, if these things really appeared, Boss Cao would not have to hold Emperor Han Xian and cry to death.

This is not the end, after passing by more than 100 wooden oxen and horses, walking into an empty school field, opposite the general platform more than 200 meters away, the five big guys guarding the left and right are the main thing.

On the left was a two-story silver tiger and an excavator-sized dark gold pangolin, and on the right was a large iron spider with teeth and claws spread out in a radius of five or six meters, and a monitor lizard or dinosaur with blades all over its body.

The machine soldier god in the center is ten meters high, resembling a Qin figurine, with steel armor and a blade in his hand, majestic as a heavenly soldier general, no weaker than the sci-fi Gundam mecha in the movie.

Liu Zai pinched a cold sweat for Boss Cao again, he was wrong just now, these are going to be in the world Boss Cao really wants to cry, and he is holding the old Liu Xiaosun and crying together.

He has heard of the legend of the trap beast, and it is rumored that the ancient princes of the hundred schools of warring states fought in chaos, and the mechanism has developed to a peak, and the master is the Mo family and the public loser, these two families have loved and killed each other for thousands of years, and almost a Chinese person knows, and the two families also fought to the first peak in that era, and both produced mechanical monsters that combined alchemical mechanism and bionics.

In the records that Liu Zai saw in the Lingquan Treasure Pavilion, these machine beasts are based on the skeleton of powerful demon beasts, with the inner pill as the core, supplemented by a more powerful body given by alchemy, and in addition to the mechanism structure designed for war, it is said that these ancient mechanics also have secret methods to seal the primordial spirit of demon beasts in the machine, and realize the unity of machine and beast, and the strength is even better than before death.

However, even in a place like the Puluo Mountain Alchemy Academy, he had never seen anything that could really move, and Liu Zai could imagine what the hell the Alchemy Academy's tech nerds would be like if they saw this.

But Liu Zheng was very entangled.

Because I can't fit my fucking ring.

The little Sumeru ring with a length of fifty zhang and a height of fifty zhang Liu Zai never thought that it would not be enough, and this windfall was a bit too big.

What to do?

He wanted to take the beast with him, but he was reluctant to give up what he had, or he would throw away the wagons, but that was the wish of his friends.

It is depressing to enter Baoshan and return empty-handed, but if you have the ability to dig the mountain, you must have the ability to move away.

Suddenly, a killing machine attacked, close at hand, Liu Zai didn't even think about it, his body did not move, and he retreated more than 30 zhang, steady as a mountain and as fast as electricity.

This retreat was retreating to the center of the school field, and Liu Zai raised his head just to meet the golden red eyes of the giant god weapon.
