Lu Xu took the soul search plate to the jurisdiction of Danyang Peak, flew for two days in a row, and finally stopped at an inconspicuous peak.

This is already the edge of Danyang Peak, and there are two reasons why Lu Xu chose to open a cave near here.

One is that this place is extremely remote, and no monks usually come here to disturb themselves.

Second, this place is located on the edge of the Zixiao Sect, and not far away is a market where scattered cultivators gather, which is also convenient for Lu Xu to do some shady transactions.

In fact, the aura here is not very strong, and it can only be barely considered ordinary. However, Lu Xu didn't need to rely on heaven and earth aura to cultivate, so he didn't care much.

After holding the spirit search disk and exploring for a while, Lu Xu flew away and shot away in a certain direction.

......

Half an hour later.

Lu Xu stood under a steep mountain peak, looked at the huge mountain wall that was more than 100 zhang high on the opposite side, and nodded.

Wielding the moon blade in one hand and manipulating several spiral knives in the other, Lu Xu began to carry out the great cause of opening up the cave.

Relying on the sharpness of the moon blade and the number of spiral knives, after half a day of hard work, a cave house that covers a large area has begun to take shape. A total of more than a dozen rooms of different sizes and two halls covering an area of acres have been opened.

Although the walls of the cave are still very rough and have not undergone any fine processing, at least they can be safeened! This made Lu Xu breathe a sigh of relief and stopped.

He then took off the cloud blanket and returned the soul plate to the deacon hall.

The cave mansion built by Lu Xu has two exits before and after, one bright and one dark, for emergencies. Therefore, after returning, he immediately put down a small magic circle with the formation flag and a dozen low-level spirit stones according to the method on the jade slip.

This formation is extremely simple, and it can only serve the purpose of simple concealment and trapping beasts. After the formation was arranged, it was still a complete mountain wall from the outside, and it was impossible to detect that there was an additional cave here.

After doing the most basic protection, Lu Xu used the moon blade to cut out a simple stone bed, hurriedly lay down and fell asleep. He was a little tired.

In the following days, Lu Xu has been busy in the cave mansion.

He first found a piece of land in Pyongyang in a hidden place near his cave, and then sprinkled some seeds of elixir.

These are all the seeds of exotic flowers and plants collected from the Surabaya Medicine Garden in the past few years, but this is just Lu Xu's method of covering people's eyes, and the elixirs he really needs have already been planted in the Linglong Secret Realm.

Then build a room into a spirit beast room, put the Void Ape in it, let it play in it, and throw it an elixir from time to time.

Immediately, Lu Xu built an alchemy room and a practice room for cultivation.

The rest of the time, Lu Xu also bought a large number of daily necessities from the nearby Fang Market, such as tables and chairs, bedding, pots and pans, landscape calligraphy and paintings, and put a set in each room. Although he can open the valley after entering the foundation building period, Lu Xu still wants to taste some food from time to time. Finally, all the walls were carefully cut and smoothed, and some light stones purchased from the market were inlaid to make the cave as bright as day.

In this way, Lu Xu's first cave mansion was preliminarily completed.

However, it is obvious that the protective ability of this cave is not vulnerable at all, and it really can't make Lu Xu'an settle down to practice. According to his thoughts, at the very least, he had to arrange an all-round forbidden method, otherwise if there was an invasion of foreign enemies during cultivation, wouldn't it be terrible to have his head on his head.

And when it comes to forbidden methods, the most common is the formation.

However, Lu Xu is a complete layman in the formation, and he can't even put the most basic formation, let alone a more powerful big formation.

Although he has the heart to learn, he has no choice but not to have this time!

Moreover, his spiritual root was extremely poor, and if it took a lot of time to learn the formation, it would be extremely unfavorable for him to advance to the Jindan stage.

Although after the foundation was successfully built, his longevity soared to more than two hundred years, but for the monk, such a little time passed in the blink of an eye. At this time, he was already in his twenties, and he really didn't have enough time, and it was even more difficult to advance to the Jindan stage than to advance from the Qi refining stage to the foundation building stage.

To be honest, Lu Xu really didn't have much hope in his heart.

The main reason why he was able to go from the first layer of the Qi Refining Period to the Great Perfection of the Qi Refining Period in such a short period of time and thus build a foundation was the Linglong Secret Realm. It was with the elixir in the Linglong Secret Realm that he could refine the elixir, so as to quickly improve his cultivation.

After advancing to the foundation building period, the original pill had no effect at all. And if you want to refine the pill of the foundation building period, you must have a pill, but Lu Xu does not have a pill for the foundation building period.

He had gone to the Zongmen's Scripture Pavilion to rummage through it, and there wasn't even a copy of the Zhuji Dan Pill in it, oh no, there was one. It's just that the name of this Danfang is called Dingyan Dan, which can make people stay young forever after taking it, but it has no effect on cultivation.

Moreover, the elixir required for the pill in the foundation building period has higher requirements for the year, although Lu Xu has a Linglong secret realm and doesn't have to care, but without the pill, it is just a mirror. And the thirst for pills for the monks of the Jindan period is even better than that of the monks of the foundation building period.

Because when you reach the realm of the Jindan period, not to mention that you want to turn the pill into a baby, it is to raise the cultivation of mana to a level, which is a difficult thing.

Therefore, taking a large amount of pills, this has become the usual way for monks in the Jindan stage to improve their mana, and at this stage, the ordinary pills in the world have long had no effect on the monks in the Dan stage.

Only the elixir refined with medicinal materials that were more than hundreds of thousands of years old and some elixirs that were generated by heaven and earth could speed up their cultivation. Therefore, most of the time of each trip of the monks in the Yudan period was used to collect extremely rare medicinal herbs.

However, taking the elixir is only an auxiliary means to improve the mana, and it can only shorten the time for meditation and absorbing spiritual energy. Diligent penance is the right way to truly turn the aura into one's own mana.

Otherwise, no matter how much pill you take, if you don't take the time to refine the aura it contains little by little, it will still be useless and will not increase any mana. After all, the external aura and one's own mana are fundamentally different things.

There have even been cases where someone has taken a large number of high-grade pills, and as a result, there has been too much aura in the body, which makes people explode and die. Therefore, casually taking pills far beyond one's own realm is an extremely dangerous thing. It's like when Lu Xu was in the first layer of the Qi refining period, he took the pill of the Solid Spirit Pill, which was an extremely dangerous thing.

In addition, when encountering a bottleneck, use the spiritual power of the elixir to rush through the level. This is a common method used by many monks and has proven to be a very effective method.

Without the help of any medicinal power, the cultivators who can break through the bottleneck of cultivation on their own are still too few in the entire immortal cultivation world, and they are all immortal cultivation wizards who can only be seen once in a hundred years!

The Heavenly Spirit Root is a person with this kind of recognized supreme qualification, and even if the mutated Spirit Root encounters this kind of cultivation bottleneck, it is inevitable that they will have to take pills to rush through the level, which is no different from ordinary Spirit Root people.

And the monks in the foundation building period are similar, there are not many pills that are useful to the monks in the foundation building period, and this kind of pill pills are even more regarded as baby bumps one by one, and they will never be known to outsiders.

Therefore, after Lu Xu was excited about the initial success of building the foundation, he gradually calmed down.

The matter of the pill can be solved slowly, but the protection of the cave must be strengthened in time.

Fortunately, there are many people in the immortal cultivation world who don't understand the way of formation, they don't know formation, and there are also formation flags and array plates, so it is easy to carry and arrange the formation magic weapon to use.

So Lu Xu decided to try his luck in the nearest Qingshifang City to see if he could find the required forbidden formation.

So Lu Xu took off the cloud blanket, carrying in his arms the tens of thousands of spirit stones that he had sold the magic weapons obtained in the forbidden land, and shot towards the Fang Market.

Although Qingshifang City is close to Lu Xu's cave, it is also close to two hundred miles away.

However, the distance of only two hundred miles, for Lu Xu, who has greatly advanced in mana, will arrive in half a day.

Qingshifang City is a scattered cultivation gathering of the city, because the entire market is built of bluestone and got its name, and is not controlled by the large sects. This Fang market is located in the territory of Qi State, which is adjacent to Yan State, and is the most prosperous Fang market in this area. Perhaps it is because it is convenient to sell stolen goods in the scattered workshop market, so this kind of workshop market is often more prosperous than the Zongmenfang market.

When Lu Xu was thinking about the matter of Qingshifang City, the flying cloud carpet under his feet suddenly sank, and it slowly fell to the ground, as if it had lost the effect of flying in an instant.

Seeing this unfavorable situation, Lu Xu was not surprised, but showed a hint of joy. It seems that it has already arrived near Qingshifang City, otherwise there would be no ban on flying. Although this Fang City is a scattered workshop city, there are still rules, and some necessary prohibitions are all complete.

Sure enough, Lu Xu, who landed on the ground, walked nearly ten miles south, and a building complex slightly smaller than Zixiao Zongfang City appeared in front of him.

The whole body is made of huge bluestone, like a small castle, which is a set of fang market order established by several immortal cultivator merchant alliances to maintain the daily operation of the fang market.

Out of caution, Lu Xu did not act recklessly, but took a transformation pill and turned into a middle-aged man with a white face and beard. I walked around the market and walked around slowly, so as to understand the situation in the city.

Unlike the Fang Market in the Zixiao Sect, there are many strange things here.

For example, the private customization of magic instruments and talismans.

For example, the domestication and sale of spirit animals.

Lu Xu walked straight into a shop that sold all kinds of magic weapons, and after asking, he couldn't help but be a little disappointed, there was no set of powerful formations in it.

He asked several shops in a row with some unwillingness, but they all shook their heads and said no. Lu Xu was a little disappointed and wanted to leave the store, but before he could leave the house, when he had just walked a few feet away, suddenly the voice of the shopkeeper came from behind him.

"This senior, please stay for the time being!" the shopkeeper smiled:

"Senior, if you want to buy a powerful magic circle in an ordinary store, I'm afraid you'll have to run in vain. The formation is only available to the big sects, and it will only sell some ordinary goods, and the real high-quality magic array will not flow out. Because the formations are all the top secrets of the sect, the formation flags and array plates that are easily leaked out will let outsiders see the flaws in the formation! For the sect, this is more than worth the loss!"

"Listen to your tone, it seems that there are other ways to get it. Lu Xu said in his heart when he heard this.

The shopkeeper laughed and said:

"Yes, there is a small auction held in Qingshifang City for the monks of the foundation building period, which is presided over by the merchant alliance of Fang City. Although a small part of the things sold there are a little problematic from the source, the goods are definitely top-notch products that are rarely seen in the outside world! I think there, the seniors will definitely be able to find satisfactory array weapons. ”

"When is the auction going on? When Lu Xu heard this, he was overjoyed.
