Yu Zhang's party walked out of the forest, and several carriages were parked outside.

Yu Chang approached and found that the horse pulling the cart was not an ordinary horse, but a high-level horse with a trace of spirit beast blood.

The horses look very strong from the outside, with thick legs, sharp eyes, sharp teeth... This kind of horse, if it runs, must really be able to travel thousands of miles in a day.

Along the way, Yu Zhang enjoyed the treatment of distinguished guests, was served comfortably, was handed a tea and snack for a while, and was held a big pu fan to blow the wind for a while, so comfortable.

Yu Zhang's expression was happy, and it could be seen that he was enjoying this high-level VIP treatment very much.

Before you know it, the scenery outside the window has begun to change, the road has become wider, many horse-drawn carriages come and go, and there are pedestrians carrying their bags and trekking on the side of the road.

Needless to say, Yu Zhang also knew that the destination of this stop, Gaochuan City, was approaching.

According to various ancient books and reports from various spies, most of the cities in the Qingxia Kingdom are built with high walls, and the materials used are not ordinary rocks and soils, but more solid special materials.

At the same time, the city wall is also equipped with various powerful spiritual arrays and mechanisms to prevent foreign enemies from attacking.

It is said that it is because in ancient times, the world was not very peaceful, and wars broke out. Not only will there be wars between different races, but there will also be infighting among human beings.

At that time, the country had not yet been reunified, and various cities sent troops to fight because of large and small disputes.

In response to the situation, countless walls were erected, forming a barrier to protect the lives of the people, guarding the last vestiges of peace of that era.

Later, the country was unified, the world was peaceful, and there were many fewer wars, but many cities still kept the city walls as a landscape, a warning, and warned future generations that peace is precious. In some cases, part of the castle wall was torn down in order to expand the territory.

And this Gaochuan City, there is the word Gaochuan in the name, Yu Zhang combined with the records in the ancient books to think, and thought that there would be a very high city wall, but he seemed to have misunderstood the word "Gaochuan".

The huge city in the distance, there is no trace of the city wall, whether it is the ruins or the existing buildings, they all tell Yu Zhang a fact, this Gaochuan City, from ancient times to the present, there has been no city wall.

Yu Zhang was puzzled, and broadened his horizons, no longer limited to the city, and turned his head to see the broader landscape.

The city is surrounded by mountains, some of which rise to the sky, while others stretch like mountains.

Yu Zhang suddenly realized that this "Gao Chuan" is simply literal, a lofty mountain.

With such a natural barrier, Takakawa Castle in the war simply occupies a perfect location, and naturally there is no need to build a heavy city wall.

Foreign invasion, not to mention the soldiers and traps that may be ambushed in the mountains, just these large and small high and low mountains are enough to make the invaders head two big.

Looking at it this way, this Takakawa Castle is indeed an impregnable city.

These natural ravines and mountains are not a small trouble for ordinary people, and even for spiritists who are not strong enough.

But for the kind of spiritualist powerhouse who is ridiculously strong, flying away and omnipotent, these troubles do not exist at all in their eyes.

The old man saw Yu Zhang staring at the city in the distance, and slowly explained: "There is a well-known story in Gaochuan City: there was a battle in ancient times, and the enemy sent a spirit king powerhouse who had reached the level of flying heaven and earth, and directly ignored all defense facilities and descended from the sky to Gaochuan City. ”

"You know, the Spirit King stage, but a powerful class that can step on the air and walk above the sky at will!

"That strong man is one against ten thousand, the army is defeated, and the spirits of all walks of life are no opponents. Just when everyone was desperate, a dark horse from a small family stepped forward and single-handedly repelled the spirit king powerhouse and saved the people of the city. ”

Since then, the man's name has been passed down through the ages and has become the subject of various folk tales. On that day, this man flew into the sky alone and fought against the enemy, which was imprinted in the hearts of the people of the entire city, and they called him Skywalker!"

The strength grading system of this world is divided into the following ten levels from small to large according to the degree of spiritual power:

Spirit disciples, spirit scholars, spirit envoys, spirit governors, spirit generals, spirit sects, spirit kings, spirit emperors, spirit emperors, spirit saints.

In fact, there is an eleventh level - the spirit god.

However, the spirit gods only exist in that ancient mythology, and no one in the present world has ever heard of anyone who can reach this level, so they are ignored and gradually forgotten by the world.

As the name suggests, a spiritual disciple is an apprentice who has just learned spiritual arts, and his spiritual power has just been formed, and his strength is weak.

Spiritual priests and spiritual envoys are stronger powers, but they are still in the introductory stage on the long road of spiritual path.

Lingdu was a watershed. Those who are promoted to the spiritual governor have increased their spiritual power exponentially, their control over the spiritual power of heaven and earth is also better, and their overall combat power has also increased exponentially.

The ability of the spirit general can be used as the general of a city, invincible and invincible.

Lingzong, as a party, can be a great power, open a sect, and pass on the teachings.

And the Spirit King is really beginning to step into the realm of the strongest in the Spirit Dao. You can defend one side of the land and be the king and hegemon.

For others, the Spirit Emperor is like an emperor who looks down on the subjects of the world, and only one word of golden words can decide the lives of others.

The power of the Spirit Emperor, like the appearance of the emperor, is admired by all the people, and the life and death of all things can be determined with a gesture.

The spiritual saint is like a saint, born out of the earth, beyond common sense, and with the power of one person, he can raise a kingdom or destroy a kingdom.

The spirit god is the true god, free from the confinement of the world, immortal and invincible.

And in this ancient battle in Gaochuan City, two spirit king powerhouses directly appeared, how can it not amaze future generations?

Yu Zhang heard that this Skywalker was so famous, he must have been worshiped as a god, at least a few statues, a few incense sticks.

Sure enough, near the gate of Gaochuan City, I saw a 100-meter-high figure, stepping on the clouds under his feet, his hands behind his back, and his robe raised, which was indeed a "Skywalker" posture.

Yu Zhang thought in his heart: "Since there have been strong people at the level of spirit kings in this realm, it is difficult to guarantee that there will be no spirit magicians of the same level in the future, and when you investigate by yourself, it is better to keep a low profile." You must know that the Spirit King is strong, in the Void Heaven Palace, he is already qualified enough to be a little lord. ”

Although Yu Zhang, as the prison warden, commands the strange people on the tenth floor of the entire Void Heaven Palace, and has a noble status, under one person and above ten thousand, but because of his young age, coupled with the fact that he fishes and jokes all day long, and does not work hard to cultivate, Yu Zhang's own strength is only to the level of a spirit general.

However, the lords of the Void Heaven Hall are all very loyal to the hall master, and they don't have much doubts about the prison director arranged by the hall master.

After more than ten years of training, this little warden can be regarded as having good abilities and living up to expectations.

Originally, this kind of incident of the disappearance of the secret agent did not need to be specially sent to his dignified warden to deal with it, and there were masters in the Void Heaven Hall who were good at disguise, but since it was the meaning of the hall master, there must be a meaning.

It is not difficult to guess that the hall master has nothing more than two meanings: one is that the warden is a human being, but he has lived around a group of demons and monsters since he was a child.

The second is to take this opportunity to exercise again.

If this hall master who saw the head and the tail had any other meaning, he couldn't guess it for the time being just based on Yu Zhang's wisdom.

However, Yu Zhang has read a lot of books in the mortal world since he was a child, and he is also quite interested in the mortal world.
