After walking for a while, Chu Batian, Uncle Dao and Chu Feng came to a relatively hidden place in the City Lord's Mansion.

In front of them was a special room. The reason why it is special is that the exterior walls of this house are all made of a strange metal, which looks indestructible.

Chu Feng knew that this was the most important place in their City Lord's Mansion - the treasury.

It can be said that Xuancheng's income and heritage are hidden in this house, so the importance of this place is self-evident.

Don't look at the fact that there is no one guarding here, but in fact, I don't know how many masters of the City Lord's Mansion are hidden secretly, and the house itself has many protection methods.

It can be said that even a strong person at the peak of the Earth Martial Realm would not be able to enter this house through a strong attack.

Chu Batian came to the door of this house, and then stretched out a hand, and a vast Yuan Force fluctuation vibrated and spread out with a special law, and then slammed into the two doors of the house.

"Hum~"

Suddenly, there was a buzzing sound from the seemingly ordinary gate. With that, there was a burst of light.

Chu Feng looked at the picture in front of him, his expression was a little serious and condensed. Naturally, he was not paying attention to the light and shadow on the gate, but watching the fluctuation from his grandfather's palm.

Strong, vast, long.

This should be a more accurate adjective.

The strength of the Earth Martial Realm is really extraordinary!" Chu Feng thought. That's right, his grandfather, Chu Batian, is a powerhouse in the Earth Martial Realm.

On the path of cultivation, the initial realm is the Juyuan realm, and the martial artists in this realm need to constantly condense the pure Yuan power of heaven and earth into their own bodies, and constantly impact the meridians in the body to open up the Yuan veins, and the Juyuan Nine Folds will have nine veins.

And after the nine veins of Juyuan is the True Martial Realm, the martial artists of this realm use their own stored nine veins of Yuan power to impact the dantian in the body, and then open the dantian to expand the Yuan vein, so the strength is several times that of the Juyuan Realm.

The realm above the True Martial Realm is called the Lingwu Realm, and the martial artists of this realm can fuse the Yuan veins in their bodies and expand the dantian into a vast Yuan Sea, and their strength is even more terrifying.

And Chu Feng's grandfather, Chu Batian, is a powerhouse in the Earth Martial Realm.

This martial realm powerhouse, compared to the previous realms, has undergone earth-shaking changes.

One of them is that the gaseous Yuan Force in the Earth Martial Realm Martial Artist Yuan Sea has been liquefied, and the entire Yuan Sea is filled with vast liquid Yuan Power. Therefore, the martial artists of the Earth Martial Realm can take off and walk on the ground, and the combat power is even more terrifying.

Moreover, martial artists who have reached this realm have the ability to refine the strange things of heaven and earth.

For example, the natural flames of heaven and earth, ice crystals, flowers and trees, and even demon beasts and spirits can be used to refine life-saving things and increase their combat effectiveness.

As far as Chu Feng knew, the reason why his grandfather was able to become the Lord of Xuan City was not only because of his own strong realm, but also because Chu Batian had once refined a fourth-order peak Purple Flame Lion Spirit as his natal object.

This demon beast spirit can multiply his combat power during the battle, and with the help of the power of Ziyan, this makes Chu Batian have almost no opponents among the martial artists of the same realm.

"Alright, let's go in together. ”

Just as Chu Feng was thinking wildly, Chu Batian's voice suddenly sounded in his ears.

Chu Feng came back to his senses, and under the leadership of Chu Batian, he followed Uncle Dao into the treasury.

Inside the treasury is a small cubicle separated by black and red wooden boards. And in each compartment, there is a row of shelves, and the shelves are divided into many compartments, on which are placed all kinds of spiritual objects.

As one of the six major cities in the Jinyang Plain, the heritage of Xuancheng is naturally not bad. After all, Chu Batian is one of the six city lords of the Jinyang Plain, and he is also a powerhouse in the Earth Martial Realm, so he naturally has a lot of hidden goods.

"Let's go!" Chu Batian reminded.

Following in Chu Batian's footsteps, Chu Feng began to tour this mansion. He had been here a few times as a child, but at that time he was ignorant, only knowing that the things in it were fun, not the value.

Entering again today, as the young master of Chu Fengxuan City, they all gasped.

"Spirit level lower grade martial arts, three needle fingers!"

"Spirit level high-grade martial arts, boom mountain palm!"

"Spiritual Rank Middle-grade Exercises, Cultivation Yuan Jue!"

In the compartment marked with the area of martial arts exercises, Chu Feng saw that there were dense old books placed in the grids on the shelves, and next to each book, there was a wooden plaque, on which the level of these martial arts exercises was marked.

This is the treasury of Xuancheng, and there are naturally a lot of spiritual objects and treasures.

Just with these martial arts in front of him, Chu Feng knew that if these things were put outside, they would definitely be snatched up in an instant.

Chu Feng casually approached these shelves, glanced at them, and walked away. Because although these martial arts techniques are full of temptation for others, they are still a little inferior to him.

Because he knows that in martial arts, there are five levels, which are spirit, earth, heaven, mystery, and sacred. In each grade, it is divided into three grades: lower, middle and upper.

The martial arts of the spirit level are only applicable to the martial artists of the Juyuan Realm and the True Martial Realm. And Chu Feng's gaze didn't stop there, so he wanted to look for a more advanced martial arts technique.

Thinking like this, Chu Feng walked towards the depths of the area of martial arts exercises. Under Chu Batian's reminder, Chu Feng naturally knew where the best martial arts in the treasury were placed.

Reaching the deepest part of the chamber, it suddenly became much more spacious. In front of Chu Feng was a huge wooden table in all directions, and on the tabletop, there were three white jade slips.

The three jade slips were all lying in a black wooden box covered with high-grade silk cloth, which made the three jade slips look even more noble.

In fact, the wooden table where these three jade slips are placed is a table made of black gold nan wood, and many special formation runes are engraved on all sides of this table to protect the safety of jade slips.

Chu Batian immediately took out a special token and waved it towards the wooden table. When even a strange light fluctuated and landed above the wooden table.

In an instant, a golden ripple appeared above the wooden table, forming a shroud-like brilliance. Chu Feng knew that it was some kind of extremely strong defensive spirit array.

Then, under the fluctuation of the token, the light began to fade away, and the spirit array also disappeared into invisibility.

Chu Feng walked over and grabbed one of the jade slips.

"It's actually a ground-level low-grade martial art!"

"The Wild Lion Destroys the Mountain Fist! Turns the lion's roar into a fist, the power is fierce, and when the force is out, the mountain collapses and the ground cracks!"

Seeing a few simple introductions, Chu Feng knew that the power of this martial art must be very powerful!

"This is a martial art that your grandfather and I got when I was young, grandpa and I can become the lord of Xuan City, this martial art can help a lot!" Chu Batian's two faint explanations have fully explained something.

However, Chu Feng was not in a hurry, but picked up the second piece of jade slip and continued to look at it.

"Spirit-level high-grade, True Yuan Gong! This technique can help cultivators improve the speed and quality of condensing the Heaven and Earth Yuan Force, and when the cultivation does not exceed the True Martial Realm, under theoretical conditions, it can increase by up to three times!" Seeing this, Chu Feng was already shocked.

Because this means that if someone can really achieve this theoretical triple speed, then in other words, his cultivation speed in the low-level realm will also be three times that of ordinary people!

No wonder it's just the spirit level that is placed here!

Chu Feng thought in his heart, and picked up the third jade slip.

"Ground-level mid-grade, Xuanjia Shield Technique! This martial technique can help cultivators refine a Yuan Force Gangqi Shield Armor with extremely high defensive power, even if it is cultivated to a level higher than the cultivator itself, it is difficult to break it!"

Seeing this, Chu Feng couldn't help but smile bitterly, "Is this to make me turn into a turtle?"

"What are you talking about, you kid!"

At this time, Chu Batian stepped forward, patted Chu Feng's head, and scolded with a smile.

"Choose, which of the three do you want!" Chu Batian said lightly.

Chu Feng smiled when he heard this, he knew that only his grandfather was so good to him, and he was willing to give him such a high-level martial arts technique to choose at will.

When Chu Feng swayed among these three martial arts techniques, an inconspicuous light suddenly flashed from the corner of his eye.

It was an extremely faint light, but it alarmed him. Chu Feng turned his head to look and found that in front of this black wooden table, there was also a very small offering table, on which was placed a black thing that looked like a jade slip.

I didn't know what was touched in my heart, Chu Feng immediately put down the three jade slips in his hand, walked towards the offering table, and then picked up the black thing on it.

At this time, the faces of Chu Batian and Uncle Dao changed, and their expressions were extremely complicated.
