Living in the courtyard, Zhou Feng and Zhou Lei both began to practice in retreat.

Especially Zhou Lei, I hope that before the trial begins, he will be able to condense his energy, so that the hope of passing the trial will be greater, otherwise it is just the cultivation of the Nine Veins Martial Artist, and he really comes to be cannon fodder and accompany the prince to study.

Zhou Lei had a lot of Ning Gang Dan on him, which was given to him by Zhou Yuanhu before he left.

With Ning Gangdan's help, Zhou Lei is not without hope of a breakthrough.

As for Zhou Feng, he had already reached the realm of a hundred steps of imperial qi, and if he wanted to go further in five days and reach the point of transforming into a tangible qi soldier, it would be a little difficult, even if he had the Ning Gang Pill to assist in cultivation, it would take at least one or two months.

After all, not everyone's qualifications are as rebellious as Zhou Chen's and have a special physique.

Seeing that both of them were cultivating, Zhou Chen did not call Zhou Feng and Zhou Lei, and left the courtyard alone.

The Zhou family has three major ground-level martial arts techniques, the Black Water True Technique, the Black Sea Angry Jiao Fist and the Thunder Yin Sword Qi Technique, the Black Water True Technique is the internal strength and heart method, Zhou Chen has long been cultivated, and he has also mastered the Black Sea Angry Jiao Fist, so there is only the Thunder Yin Sword Qi Technique.

If you want to cultivate the Thunder Sound Sword Qi Technique, you need special aids.

That auxiliary thing is the Thunder Yuan Stone that contains the power of thunder.

Lei Yuan Stone is very rare, and it can only be bred in a special environment.

Thousands of meters in the sky, there is the existence of thunderclouds, which are full of violent thunder power, and these thunder powers can only be bred after dozens of hundreds of years of accumulation.

If you want to collect Lei Yuanshi at a height of thousands of meters, even a martial arts master can't do it.

Therefore, only by waiting for thunderstorms can special means be used to draw down some thunder stones.

The quality of these Lei Yuan stones is average, and they are only the heavenly materials and earth treasures of the lower grade of the ground level, but because of their scarcity, their value is comparable to the heavenly materials and earth treasures of the upper grade of the ground level, and the market price is more than 1,500 yuan crystals.

Zhou Longyue was also in a mission, and by chance he obtained a Lei Yuan Stone, and only then did he cultivate the Thunder Yin Sword Qi Technique.

Zhou Chen had two thousand yuan crystals on his body, which was used to buy Lei Yuan Stone.

Lei Yin Sword Qi Technique, if cultivated to the peak, the power is comparable to some heaven-level martial arts.

......

Treasure Pavilion is located in the most prosperous central area of Shangyang City, twenty or thirty miles away from Qingyun Temple.

At the intersection of two criss-crossing streets, there is a majestic nine-storey building, which is magnificent and magnificent.

When Zhou Chen arrived here as fast as he could, he was also a little shocked, the Treasure Pavilion also has a branch in Blue River City, but the scale is far from being comparable to the Treasure Pavilion here.

Treasure Pavilion, in the various cities of the Great Yue Kingdom, there are branches, and the background is very deep.

The capital of Dayue also has the existence of the Treasure Pavilion, and it is said that even the people in the royal family dare not be presumptuous when they arrive at the Treasure Pavilion.

It is rumored that this Treasure Pavilion is not the power of the Great Yue Kingdom, but the super giant force that spans the entire Eastern Wilderness, and the person in charge of the Treasure Pavilion of the Great Yue Country is only one of the principals, but it also has a martial king-level cultivation.

There are more than a dozen entrances to this Treasure Pavilion, and as far as Zhou Chen can see, there are figures coming in and out everywhere.

Zhou Chen restrained his mind for a moment and strode in.

Then, a very large hall appeared in front of him, with people coming and going, extremely lively.

In the lobby, there are many counters, and there are a variety of items in the counters.

Elixirs, elixirs, weapons, beast cores, martial arts exercises......

As far as the eye can see, all kinds of rare treasures fill the eyelids, and looking at the quality of the weapons and elixirs, none of them are ordinary.

The Treasure Pavilion is worthy of the claim that as long as you can afford the price, no matter how precious things are, you can get them.

If it weren't for the background of the sky, he would have been eaten to the point that there were no bones left.

"Hehe, this little brother, what do you need?"

While Zhou Chen was staring at the many items in the counter, a gray-clothed guy walked over with a smile on his face.

"Is the little brother here to participate in the Ascending Conference?" The gray-clothed little guy took out a cyan long sword from the counter and introduced: "The Qingfeng Sword, cast from a hundred refining bronze, blows hair and broken hair, extremely sharp, and there are also refiners inscribed with runes, reaching the top grade of the human rank, even if it is a Qi Vein Realm martial artist, as long as it is infused with internal qi, it can pierce the outer Gang-level body protection Qi." ”

"The little brother took it to participate in the ascension conference, which is like a tiger with wings. ”

Zhou Chen glanced at the cyan long sword, which was carved with crooked runes, flashing with a faint luster.

In the Eight Desolations World, the mainstream of martial arts cultivation is the combat system, but there are also auxiliary professions among them.

For example, the refiner inscribes runes on the weapon to enhance the power of the weapon.

A good weapon can make people leapfrog the challenge and defeat the strong with the weak.

A human-level high-grade weapon, if it is in the hands of a Waigang-level samurai, can increase its own attack power by three or four percent, and if it has armor, it can also increase its defense by three or four percent.

A samurai who has just entered the Waigang level, holding a human-level high-grade weapon and a human-level high-grade armor, can definitely defeat a samurai who has reached the peak of the Waigang level and turned into a tangible qi soldier.

However, Zhou Chen was not interested in these weapons.

However, the human-level high-grade weapons are of limited help to the Neigang-level warriors, and the runes in the ground-level weapons are more advanced than the human-level, and they need the true yuan to urge, so it is useless to buy them.

The gray-clothed little guy was not embarrassed, and continued to introduce the rest of the items to Zhou Chen.

"I need Lei Yuanshi!

Zhou Chen interrupted the introduction of the gray-clothed guy and went straight to the point.

"Lei Yuanshi!" The gray-clothed little guy was stunned for a moment, and then said: "Yes, yes, of course, the little brother came at the right time, the day before yesterday, this pavilion just entered a batch of goods, among which there is a Lei Yuan Stone, although this Lei Yuan Stone is only a treasure of heaven and earth under the ground steps, but in terms of rarity, it is comparable to the treasure of heaven and earth, so it is not on the first floor, but on the fifth floor, and the price is ......"

"The price is not a problem, since I want to buy Lei Yuanshi, I must be ready for the corresponding Yuanjing. ”

Zhou Chen opened the corner of the storage bag, revealing a mountain of yuan crystals piled up inside.

"This little brother, please follow me up to the fifth floor. ”

Seeing Yuan Jing in the storage bag, the gray-clothed guy was more respectful to Zhou Chen, and led Zhou Chen to the fifth floor.

The Treasure Pavilion has nine floors on the first floor, and the higher you go up the counter, the more valuable the items are placed in the counter.

The first and second floors are generally prepared for Qigang Realm warriors, and most of the items are only of human class, and the price generally ranges from a dozen yuan crystals to dozens of yuan crystals.

On the third floor, all of them were earth-level treasures, worth hundreds of yuan crystals.

The value of the treasures on the fifth floor is even higher, almost all of them have reached the top grade of the ground level, and they are worth nearly 1,000 yuan crystals.

It is rumored that on the top nine floors of the Treasure Pavilion, there are treasures that even martial arts masters are blushing at.
