After the Miracle War, the whole cloud gradually declined in turmoil.

Countless oases have been reduced to deserts, countless dynasties have been wiped out in dust, countless city-states have collapsed into ruins, and countless lives have disappeared like a cloud.

Li Bai's hometown is relatively lucky, perhaps because it is very close to Chang'an, and the people there are no different from the other side of the Great Wall in terms of cultural identity, so after the outbreak of the war, Chang'an's iron hooves did not trample there.

At least, not yet......

The year he left his hometown, Li Bai was twelve years old.

That year, he stepped into the hinterland of the desert in the clouds, wanting to study in the city of a thousand caves, where the legend holds "endless knowledge".

At that time, he was young and naïve, eager to learn.

And the Thousand Caves City also welcomes all seekers like him.

However, Thousand Caves City is not such an easy place to find, Li Bai, who is still a child, has gone through a lot of hardships to finally find the location of this legendary place, and the Lord of Thousand Caves City also gladly accepted him, a student from afar, and was even willing to provide him with food and lodging, so he stayed like this.

Time flies, more than a month has passed in a blink of an eye, and Li Bai at this time has gradually become accustomed to the life of Thousand Caves City.

As the name suggests, the "City of a Thousand Grottoes" is composed of countless grottoes of different sizes and structures, all of which are in the shape of a beehive, but each of them is different: the dome of the city is as high as the sky, and the deepest part of the Thousand Grottoes stretches into the ground like a labyrinth, and even the lord of the city does not know where the end is or where it leads.

90% of the city's inhabitants lived in the area near the entrance, and foreign merchants and traveling scholars traded and exchanged here, and only those who were able to comprehend the illusions of the grottoes would venture into the depths of the caves, but that ...... There is also a limit.

It is often rumored in the city that people went deeper and deeper into the grottoes in search of deeper enlightenment, and eventually never returned.

Li Baizi had also heard this rumor, but he didn't care about it.

Li Bai's days here are very simple, except for eating and sleeping every day, he almost spends the rest of the time absorbing knowledge in those "phantom grottoes" in the city.

For him, being able to travel through those Sumeru illusions is also a pleasure in itself.

Of course, at this time, he did not know that people like him, who "can read the knowledge contained in the grotto without the help of external objects", are actually very rare in this world.

Most of the people who came to study in the Thousand Caves City did so by renting expensive texts or using even more expensive sacred relics made of the jade of life to comprehend the illusions in the Thousand Caves City—it was an extremely rare talent to be able to directly experience the Sumeru Illusion with one's own divine consciousness and gain enlightenment.

On this day, Li Bai went deep into the "Thousand Grottoes" as usual, came to the farthest place he walked yesterday, and advanced another grotto.

After stepping into it, Li Bai wanted to immediately start to comprehend the illusion on the wall, but unexpectedly, on a stone wall, he unexpectedly found two lines of inscription - "The sword says that there are no heroes in the clouds, and the stone knows that there are heroes here." ”

After reciting those two lines silently, Li Bai was also surprised in his heart: "Who dares to say such crazy words?"

Surprise is surprise, but he didn't take it too seriously, anyway, this nick did not affect the illusion generation on the stone wall, Li Bai still continued to do what he should do.

When his spirit was concentrated, the murals in the grotto began to flow as if they were "alive", turning into various flashes of light in mid-air, enveloping him.

As the so-called three thousand worlds, a thought is eternal, in this state of "concentration", Li Bai seems to have experienced the rise and fall of a civilization and witnessed the ups and downs of an era.

And when his consciousness returned to reality, he suddenly realized something else about the two lines of poetry on the wall.

At this time, Li Bai looked at the two lines of words again, and only felt that the stroke was vigorous, and between the waves, he was full of pride, which coincided with the illusion mirror and the knowledge he had just experienced, just like a kind of "summary" and "annotation".

At this moment, Li Bai didn't think that the person who carved this word was a madman, but was curious: Where is this "master" now?

With this in mind, he moved on to another grotto to see if there were any similar inscriptions in the vicinity, but he looked around in the nearby grottoes and saw nothing else.

Just when Li Bai was a little disappointed and felt that there might be only one place in this inscription, he suddenly saw two other lines of words in another cave separating several grottoes - "Play the sword and sing and play the sad sound, and the lonely thousand caves are worried." ”

Looking at the handwriting, you can see that the two lines of words from the previous one are from the same person.

Now Li Baike became interested, and he began to search the nearby grottoes, trying to find out how many "annotations" of this master there were, and in the process of searching, he gradually discovered that these inscriptions actually have a certain pattern.

In this intricate arrangement of grottoes like beehives, if we connect these caves with inscriptions from the perspective of God, we can see that the direction of this "line array" coincides with the style of this person's calligraphy.

Li Bai was very clever, and quickly thought of this, and according to this idea, he successfully guessed where the next inscription would appear, and accelerated his pace to go deeper into the thousand caves where the inscriptions were left.

The young man, who was so excited about his discovery, forgot the time and how far he had come, and before he knew it, he had arrived in a zone that no stranger would ever set foot in.

After passing through one unfamiliar grotto after another, suddenly, the sound of sword dancing faintly came from the front......
