Hearing Wang Haoxuan say this, the old man said without thinking: "It depends on how the cultivation of Daoist friends is, but it will have an effect of at least two days!"

The old man looked at Wang Haoxuan, rolled his eyes, and then said: "However, if you want to retreat, you should mind that Daoist friends use Bigu Dan, its effect is relatively stable, and one can be used for three days!"

Wang Haoxuan was taken aback, he didn't expect that there was this kind of elixir, which was the most suitable for his current situation, and immediately asked:

"I don't know what the price of Bigu Dan is?"

"Haha, it's not expensive, it's just a first-level and lower-level elixir, a bottle of a hundred low-level spirit stones!"

After Wang Haoxuan thought about it for a while, he remembered the formation used by Mu Nan, if his cave mansion was also protected by the formation, he wouldn't have to worry about the cave mansion being discovered when he was in retreat and cultivating, so Wang Haoxuan asked again: "I still need some formations, but I haven't learned the basic knowledge of formations, so I don't know if I can use them?"

"Hehe! This is easy to say, the equipment of the general formation contains three parts, the array flag, the array plate, and the high-grade spirit stone. People who have not learned the formation www.biquge.info pen fun pavilion can use a simple formation flag, just like a refining magic weapon, and then use the spirit stone as the base to arrange a simple formation, but the formation formed by this method is mostly not very effective, the most commonly used is the concealment formation, the exploration formation and the defensive formation, but the defensive formation has long been sold out, and the above has not been replenished. ”

It's not bad to have a concealment formation and a probing formation, so the security of the cave can be higher. Wang Haoxuan thought about it again and felt that there was nothing he needed, so he told the old man what he needed.

Ten bottles of Bigu Pill, three bottles of Five Void Pills worth more than three thousand five hundred low-level spirit stones, followed by these two sets of array flags, a total of two high-grade spirit stones were spent, and now Wang Haoxuan only has one high-level spirit stone and a few middle-level spirit stones on his body, and the low-level spirit stones have long been used in the flight of the sword.

Afterwards, Wang Haoxuan chatted with the old man casually for a while, exchanging cultivation experiences with each other.

In the process of communication, Wang Haoxuan inadvertently said that when he first arrived here, the old man happily gave Wang Haoxuan the forbidden token of Fang City and a jade slip.

After getting the ban token from Fang City and lifting the ban, Wang Haoxuan once again casually exchanged with the old man for a while, then hid his body again, and returned to his cave mansion.

Immediately afterwards, Wang Haoxuan took out the two sets of array flags, carefully investigated, and found nothing abnormal, and then put them away, after all, there is no need to worry about refining the array flag for the time being, he only has a high-grade spirit stone, and it is also mentioned in the jade slip that introduces the use of the formation that a high-level spirit stone can last a set of array flags for a month at most, such a high cost, how can he let him accumulate some more spirit stones in order to retreat and cultivate.

Subsequently, he spent three days, spending most of his time refining the Flame Blade Talisman and a small part of his time refining the Array Banner. A total of more than thirty flame blade talismans were refined, although a dozen were lost halfway, but fortunately, there was a soul rejuvenation spell, which was just a waste of some talisman spiritual liquid.

Wang Haoxuan changed his appearance, concealed his aura and body shape, and flew towards the Tianyi Pavilion Imperial Sword.

With Wang Haoxuan's current cultivation, if he wants to sell so many spirit runes this time, he is afraid that it will arouse the covetousness of people with bad intentions, and Tianyi Pavilion is powerful, so the transaction must be more assured.

Despite this, Wang Haoxuan did not plan to sell these spirit runes in Tianyi Pavilion at one time, with the help of the concealment technique, he changed his appearance five times, and finally sold all the spirit runes safely between Fang Market and Tianyi Pavilion.

At the same time, Wang Haoxuan bought some Bigu Dan and the Five Void Pills, and there happened to be only thirty high-grade spirit stones left on his body, with so many spirit stones and pills, there was nothing to worry about after a year of retreat.

Wang Haoxuan, who returned to the cave, inserted the array flags into the stone wall one by one according to the method in the jade slip, and inlaid five high-level spirit stones on the grooves of the two main array flags in the center of the hall.

Immediately, Wang Haoxuan stood in front of the array flag, pinched the spirit decision with his hand, and stimulated the array flag. After a while, a layer of fog gradually appeared in the cave, and the fog became thicker and thicker, and soon Wang Haoxuan couldn't see his five fingers, and at the same time, his divine sense was only about one meter away from his body.

After a stick of incense, the array flag was finally fully activated, and the mist slowly dissipated under the control of Wang Haoxuan's divine sense, and the hole in the mountain wall, the stone wall seemed to be slowly healing, and the hole disappeared after a while, and the new mountain wall was no different from other places.

At the same time, a panorama of the cave appeared in Wang Haoxuan's mind, including the scene of one meter around the cave, which made Wang Haoxuan feel pleasantly surprised, with these, even if someone found out about it, he could know it at the same time.

However, Wang Haoxuan faintly felt that something was wrong, if someone with stronger strength than him came, wouldn't he become a turtle in an urn in the cave mansion.

"No, you have to quickly open up another secret passage, and you can escape at a critical time!" Wang Haoxuan thought so, and went to the bedroom to observe carefully.

Then Wang Haoxuan's imperial sword flew out of the cave and flew towards the bottom of the mountain wall, and after reaching the bottom, he glanced around a few times, pondered for a while, and with a flash of light in his eyes, he made up his mind.

At a place about ten zhang above the bottom, Wang Haoxuan found a reluctant place to stay, and slashed the spirit sword fiercely.

It took two days for Wang Haoxuan to finally connect this passage to the bedroom, and the intricate route made him feel a little headache, if he didn't know the exact route, he would definitely be dizzy by this passage.

Subsequently, Wang Haoxuan blessed himself with light spirit magic, carried a boulder of hundreds of catties, and smashed it towards the only exit under the mountain wall, and then modified it a few times, so that people could not see anything unusual, and came to this sealed exit from the passage in the bedroom, and cleverly opened up a crack from it that could only make the child pass sideways, because Wang Haoxuan had a transfiguration technique, he could change the size of his bones, and he could also pass through such a crack safely.

In this way, Wang Haoxuan could finally feel at ease, and then he returned to his cave mansion and changed into the dust removal clothes issued by the Huangshan Sect.

There is a sign of the Huangshan Sect on this piece of clothing, and he does not dare to wear it rashly in the outside world, but here, he has to retreat for a long time, and there will inevitably be a lot of dust and other things on his body, and wearing it can save a lot of unnecessary trouble.

Sitting cross-legged on the stone bed, Wang Haoxuan successively swallowed a Bigu Pill and the Five Void Pills, holding a spirit stone in his hand, running the cultivation method of the Thunder Fire Technique, so that the spiritual power refines the medicinal power in the Five Void Pills.

The huge medicinal power of the first-grade high-grade elixir slowly flowed through the veins with the spiritual power, and finally returned to the dantian, forming a pure fire attribute spiritual power.
