Myriad Paths

Just as he exclaimed, Li Qi felt a force strangle his vocal cords.

"No, speak." The great witch repeated.

Li Qi nodded.

But you really can't blame him just now.

He felt the breath of dragon vein!

I really know that Yun Yun's clear feedback gave him the same feeling as the investigation terminal, that is, the huge avenue that runs through all the worlds and is almost indescribable in words!

He suppressed his emotions and continued to move forward silently with the great witch.

On the way, the great witch began to explain to him.

"Aren't you curious about what the dragon vein is? I happen to be here tonight, so I will take you to see where one of the devices closest to the dragon vein, the second-level peak humane magic weapon, is located."

Li Qi naturally remembered the request not to speak, so he just shut up and followed.

Then, soon, Li Qi saw the 'machine' in this hole.

It's true, mechanical.

It is not the ancient architectural style common in the Tang Dynasty, nor has it integrated the magic weapon and the circuit into an integrated terminal magic weapon.

Rather, it is pure machinery, with countless rotating gears meshing with each other, the complex mechanical structure vibrating, and the perfect escapement and balance spring system arranged on the rotating frame of the bearing.

Deep underground, beneath Chang'an, there is another Chang'an!

Underground in Chang'an is a mechanical city!

This is not the hidden cave that Li Qi had guessed before, but a city!

Under the neat and orderly streets of Chang'an is a shadow-like mechanical city!

These machines are all interconnected structures, arranged calmly underground, and can be rotated, disassembled, and reorganized at will. Through a specific center, the surrounding three mutually perpendicular coordinate axes can be rotated at will.

Just like a clock and a single-tooth carrying machine, the transmission between mana and the exquisite mechanical structure transmits commands one level after another.

These machines are made of an alloy that Li Qi doesn't recognize, and are made with extremely good processing techniques. Some servo lines composed of optical cables are surrounded by many hydraulic pistons in the center, and there is a complete set of protective equipment on the outside. Flap.

Impeccable and flawless, no matter how you look at it, this is an exquisite machine with self-consistent logic and endless cycles. It can run for a hundred thousand years without stopping if left alone.

When watching the city in action, one can't help but feel a sense of order.

It was so complex, so exquisite, with trillions of parts used to create this great thing that Li Qiguang could feel his brain twitching just by looking at it.

He had to put away his true knowledge and no longer investigate carefully, but only used his eyes to analyze.

If he kept unfolding his true knowledge, he was worried that his brain would be boiled. The things here were too complicated, and his body, which was used to information flowing into his brain, would find it unbearable!

The great witch led Li Qixing among them.

As he walked, he explained to Li Qi: "This is the master of all terminals and all public facilities in the entire humanity. It is the basis for the smooth operation of Chang'an."

The ground, houses, and various infrastructures in Chang'an are all magic weapons.

It's like all human cities on Earth are industrial products. No one would use thatch to build houses in the city. Even the ground is covered with cement and asphalt, and the same is true in Chang'an.

It's just an industrial product turned into a magic weapon.

The great witch walked steadily, as if he was not surprised. As he walked, he explained to the frightened Li Qi: "This is the magic weapon closest to the dragon's veins."

"The pinnacle of the second grade, the ultimate product created by the joint efforts of Reason and Humanity, the 'Cardinal of All Realms', the origin of all terminals, and the core of the endless network of the Tang Dynasty."

"The energy source of the cardinals of all realms is the human dragon vein. You can directly communicate with the human dragon vein here, but you just need to feel it. Don't look at it, you will die."

As he spoke, the great witch passed through the infinite mechanical structure and led Li Qi to a huge pipeline.

It was really huge. Li Qi even thought he was standing on flat ground. The ground around him was extremely flat and slippery. The whole body was made of some kind of metal he didn't recognize, and it didn't emit any energy fluctuations.

If he hadn't looked far into the distance, with his eyesight he could see a circular interface connecting the pipeline in the distance, and he would have even thought it was a main road.

And that 'distant place' was really far away. Li Qi conservatively estimated it to be about a few thousand miles.

From such a distance, you can still see the interface of the prototype. In addition to Li Qi's good eyesight, the reason is that the interface is really too big.

As long as it is big enough, you can see it. Even if the distance between the earth and the sun is so far, you can still see the sun from the earth.

Li Qi couldn't estimate how big the circular interface was, as it was beyond his observation ability.

The great witch walked on the pipeline and took steps at will: "The pipeline under our feet is a tributary of the Dragon Vein. Remember, don't look at it casually, you will die, and I won't be able to save you by then."

He repeated this twice.

Originally, Li Qi wanted to use Zhenzhi to check the pipelines under his feet, but he stopped immediately after hearing this.

Life is important, life is important.

"Then, tonight's destination is also my destination. Once you get there, go back." The wizard led Li Qi from the pipeline to another path.

In this place, there are countless paths that shuttle through various facilities. These paths are twisting and twisted, and extremely secretive. If Li Qi is left alone, he will probably get lost as soon as he leaves.

But without these paths, I'm afraid no one would be able to travel through the interior of this huge machine.

Follow the big witch and leave the pipeline.

Then, Li Qi saw a house.

The houses in this place…

So weird.

The great witch quickened his pace and quickly walked to the house.

Li Qi followed closely behind.

Inside the house, Li Qi saw the existence of people in this underground mechanical Chang'an for the first time.

Standing inside were two officials who seemed to be from Chang'an.

One of them stood up and said: "Mr. Mixin, the two of us are responsible for the visit to the 'seismograph' agreed upon this time. Who is this behind you?"

"It's one of my younger students who came to see it with me. Don't worry about him. Just let him see the outside. Don't let him in inside."

The two looked at each other awkwardly, and then one of them said: "...I may need to ask for permission. The original agreement was only for the gentleman."

"Well, if it doesn't work, forget it." Da Wu didn't hesitate too much and agreed readily.

Li Qi remembered his previous warning not to speak, and stood still without speaking.

However, he heard a term.

Seismograph...

Is it the seismometer that I understand?

Li Qi had some doubts in his heart.

Soon, the request for instructions was completed.

The two of them saluted: "Please come in, but you must stay on the outside as you said."

"Of course, although there is competition, this credit is always there." Da Wu said.

It seemed that they really trusted each other's character, so Li Qi entered what seemed to be a confidential agency in such a grand manner.

As soon as he came in, Li Qi understood why the great witch brought him here.

Here, ordinary people may not feel anything, except for a little dizziness, almost nothing.

However, for Li Qi, who really knows Yun, this place... is simply...

Simply...

No, he couldn't describe it.

Because, he saw countless things that were similar to Zhenzhiyun.

No, this is not Daoyun, this is a avenue!

The natural force between heaven and earth ripples at extremely fast frequencies, forming invisible strings one after another.

I don’t know where these strings are connected to, but an endless number of strings spread outward. Every second, every string seems to be transmitting at extremely high frequencies, surging with ripples, and then spreading itself out. The fluctuations are transmitted internally.

What's inside?

Although Li Qi had not seen it with his own eyes, the great witch just said that there was a 'seismograph' inside.

A machine called a seismometer is responsible for receiving the information from all these strings and then gathering it together.

Countless densely packed strings spread from the seismograph to different places and continued to extend. Li Qi could not imagine how much this thing could detect.

The ‘strings’ here are all strands of Taoist rhyme.

However, a simple one seems to be much worse than a true rhyme.

But there are countless strings here.

This is not a ‘dao rhyme’, but a complete avenue!

Daoyun is just some fragments of the Great Dao. Take one out of it and call it Dao Yun. But these countless roots are combined to form a Dao. Its personality and performance are countless times that of true knowledge!

The great witch seemed to be able to feel the existence of the avenue around him.

He sighed: "The seismic instrument formed by the combination of reason and humanity is embedded in the cardinals of all realms. Its strings are endless and cover the world. Nine tribes from all directions, between the mountains, rivers, land, caves, heavens and blessed lands, the five insects and five immortals are all aware of good and evil. , Listen to the virtuous and foolish, I saw it with my own eyes today, and it is indeed worthy of its reputation. "

"Young Master Qi, just stay here. Don't move around. Otherwise, you will die here. I will go in first. You stay here... for an hour. Someone will pick you up after an hour."

"Keep your mouth shut from now on, just pretend you haven't been here and just do what you normally do."

Upon hearing this, Li Qi immediately bowed and saluted, but still did not speak.

The great witch seemed satisfied with Li Qi's silence. Then, he turned and left, disappearing into the depths of the room with the two human beings.

They are probably going to see the true body of the 'seismograph'.

That was not a place Li Qi could look at.

However, just these peripheral fluctuations were enough for Li Qi to be surprised.

He sat down cross-legged and closed his eyes.

He began to 'understand' these Taoist rhymes nearby.

Of course it's not the kind of illusory enlightenment. Sitting there and thinking about it, that's not called enlightenment, that's a waste of time.

The word "paralysis" here refers to the meaning of "exploration". How can you explore while sitting still and dreaming?

True enlightenment is to explore the nature of this avenue bit by bit, understand and record the parameters, so that you can better understand this avenue.

He began to collect information seriously, make statistical data, make analysis tables, and summarize the properties.

Expand the true rhyme and tentatively touch one of the strings.

Taken alone, true knowledge seems to be deeper and more sublime than this.

Therefore, this tentative contact was successful.

However, there was no reaction at all, and Li Qi could only vaguely feel some sounds.

It was noisy, the sound of countless people talking.

It's like the sound of countless people chirping on a busy street.

He changed a string and tried again.

This time, there was a sharp high-frequency hissing sound, similar to the hissing sound of a radio.

Tried several wires in a row, different sound each time.

But it was always noisy and meaningless, like it was all just noise.

Li Qi fell into deep thought.

He rummaged through his memory for records about the seismometer, and at the same time thought about what these things represented.

"Waiting for the Wind Earthquake Instrument...the cover is bulged, shaped like a wine bottle, decorated with the shapes of turtles, birds and beasts in seal scripts, covering all directions. If there is an earthquake, the dragon will vibrate, and the machine will spit out pills, and the toad will hold it. The vibrating sound When it stirs up, those who are waiting will be aware of it, and if they look for its aspects, they will know where the shock is." Li Qi recited this passage silently in his mind.

The meaning of this passage is to talk about the working principle of the seismograph.

"is that so?"

Li Qi looked at the countless strings.

These things... are collecting sounds?

Then, countless vibration information is conveyed to the seismometer through these strings, and then analyzed?

I can’t understand those voices. Is it because the amount of information is too large or because it’s encrypted?

But in any case, only the seismograph inside can analyze it.

In this case...

For what purpose did the great witch let him in?

What can be guessed is that coming here is not without cost. The great witch must have paid extra chips to humanity in order to stay here for an hour. He must make good use of it.

First collect the data and think about how to use it.

Thinking of this, Li Qi stopped wasting time.

Zhenzhi Yun used all his strength, coupled with his own brain and senses, and began to 'understand' the avenue here.

As a lot of data poured into his brain, Li Qi started his work.

However, one hour is too short.

Soon someone came to him and asked him to get out of here.

Li Qi had no choice but to force him to stay, so he had no choice but to get up and follow the other party out of here.

Before leaving, he took a deep look at this mechanical city.

There are actually such magnificent buildings built underground in Chang'an.

These underground things are the reason why Chang'an is so glamorous. All modern institutions in Chang'an are built on these machines below.

Then...is it only available in Chang'an?

Most of the cities in the Tang Dynasty should be like this, right?

In other words, there is such a terrifying magic weapon buried under every large city. It can maintain people's livelihood during normal times, but in wartime... I'm afraid it can also be a big killer.

And... can this be worthy of reaching the second level peak?

Li Qi was suspicious.

The so-called second-grade peak magic weapon 'Cardinal of All Realms', the one under Chang'an is only a small part of the opponent's.

The true body of the cardinals of all realms is probably all the cities of the Tang Kingdom in the entire world...wait, it doesn't stop! It should be the automatic machines under all the cities in the world and all the Tang Dynasty!

In this way, everything will be explained!

Why can terminals connect to other terminals without delay, even if they are hundreds of thousands of miles apart, or even in many worlds?

The fundamental reason is that the terminal itself only needs to connect to the small part of the cardinals of the worlds below the city, and then other things are completed within the cardinals of the worlds.

The main body of the Cardinal from all realms is probably not these machines. This is just his external manifestation. In fact, it runs through the heavens. Every small part of it appears under a city of Tang Dynasty, providing these cities with the necessary resources. Automated service!

The more Li Qi thought about it, the more his scalp became numb.
