After two days of cautious flight, Wu Yan returned to the Five Elements Peak of Xiuzhenmen. As usual, he pretended not to know about the man who was hiding nearby to monitor his movements.

With his current disguise and concealment techniques, even if Zhao Wugui and Lei Chuang really followed him, they would be dumped by him and couldn't find the north. Such an insignificant little person, he didn't pay attention to it at all. What's more, this person's existence can also paralyze Zhao Wugui and Lei Chuang.

After returning to the Five Elements Cave, Wu Yan couldn't wait to take out the few things he had bought in the Danqi Pavilion and check them out one by one. It took more than ten days, and after repeated practice, he was completely familiar with the use of the Dark Bronze Ruyi Shield and the Black Brick Rune Treasure.

Then, he took out all the magic weapons on his body, put them in front of him and looked at them one by one, he was ready to classify them, and allocated how to use these magic weapons and talismans in the future.

Attacking magic weapons and talismans, he now has the Molin Sword, the Red Evil Banner, the Black Brick Rune Treasure, the Purple Gold Flying Knife Gourd, the Black Bead Magic Weapon, more than 20 low-level attack talismans and a few mid-level spell talismans. Among them, the Molin Sword and the Red Evil Banner are both top-level magic weapons, and they have their own strengths and weaknesses in terms of power. Listening to Mo Ao, if he can succeed in building the foundation, the Mo Lin Sword can exert even more power. And this Red Evil Banner also has some special functions. A notebook obtained from Jiang Xiekong's storage bag remembers that this Red Evil Banner has an even more vicious name, called the Evil Soul Banner, which can devour Yin Evil Ghosts and constantly increase its power. Nowadays, there are only more than 100 evil spirits in the Red Evil Banner, so it is also called the "Hundred Ghosts Evil Soul Flag". If there is a chance to devour more Yin Souls, this flag can also reach the "Thousand Ghosts and Evil Spirits Banner" and "Ten Thousand Ghosts and Evil Spirits Banner". If you can absorb and devour the Yin Soul to reach 100,000 in the future, with a special sacrificial refining technique, you can even refine this flag into a magic weapon "Ten Thousand Ghosts and Evil Soul Banner". In other words, this Red Evil Banner is a magic weapon that can be upgraded.

Needless to say, the power of the Black Brick Rune Treasure is self-explanatory. However, he is only a cultivator in the Qi refining period now, and he can't give full play to the power of this rune treasure, and the power that he can exert now should be on par with the Molin Sword and the Red Evil Banner.

The purple gold flying knife gourd and the black bead magic weapon are both mid-level magic weapons, and their power is limited, but they can be used as auxiliary magic weapons.

Defensive magic weapon talismans, he now has a high-level green turtle shell magic weapon, a top-level Xuantong Ruyi shield, as well as five mid-level defense talismans, and one high-level flying talisman.

As for the Ink Viper vine seeds and various poisons, of course, they can also be used as auxiliary means of attacking and pestering the enemy.

Wu Yan had already cultivated the first layer of the Divine Cultivation Technique. His current divine consciousness should be equivalent to the divine consciousness power of a monk in the early stage of foundation building. Therefore, he was going to retreat for a period of time and practice the method of controlling several or even a dozen Dharma weapons at the same time.

Time passed in a hurry, and Wu Yan was in retreat in the Five Elements Cave for another three full months.

One day three months later, the stone door of the Five Elements Cave opened, and Wu Yan walked out with a slightly excited face. As soon as he came out, he took out the banana leaf boat magic weapon and flew to the medicine garden.

Half a day later, he returned to the Five Elements Cave again and closed the stone gate.

Half a month later, the stone door of the Five Elements Cave opened again. Wu Yan walked out of it with a gloomy face.

After the first three months of retreat and cultivation, Wu Yan finally practiced the distraction technique of controlling seven or eight magic weapons at the same time.

After practicing, Wu Yan spent another day adjusting his state, and then took three copies of the twelve elixir materials needed for Zhuji Dan from the medicine garden, counting the one purchased from the Dan Pavilion, a total of four materials, and he entered the Earth Fire Alchemy Room of the Five Elements Cave, ready to try to refine Zhuji Dan.

In the previous two years or so, when he was refining the three pills he got from the Zangjing Pavilion, "Juyuan Dan", "Qi Replenishing Pill", and "Dingyan Pill", he had already practiced the skills of alchemy very well. Especially in refining the "Qi Replenishing Pill", he already has a seventy percent success rate. And the "Dingyan Pill", the success rate is too low, mainly because of the several elixir materials selected in it, and the attributes are conflicting, but he also refined it into a furnace, a total of four. He tried to take one of them himself, but he didn't seem to have changed much, so he didn't care much about the other three, and threw them in the storage bag at random.

Who would have thought that this refining of Tsukidan would be a bizarre failure. Of the four materials, none of them succeeded. This is simply a unique thing for Wu Yan, who has already mastered a lot of alchemy skills.

Wu Yan had stayed in the Great Perfection of Qi Refining realm for almost half a year, and he was full of unprecedented desire to build a foundation. However, after several attempts, he thoroughly realized how ordinary his qualifications were, and how difficult it was to build a foundation for this Qi cultivation technique. It seems that without the help of external objects, it is almost impossible to build a successful foundation.

However, the failure of refining the Zhuji Dan four times in a row made Wu Yan suddenly realize that it was very likely that there was something wrong with the Zhuji Dan's Dan formula. After all, the materials he chose to refine this Zhuji Dan were all substitutes, and the materials needed for the original Dan were all elixir spirit herbs that had become extinct in the Immortal Cultivation Realm. Who knows what unexpected changes will emerge after thousands of years of evolution.

In order to figure out what the problem was, Wu Yan went to the Scripture Pavilion again.

After spending the price of ten spirit stones and smiling at the money, Wu Yan walked out of the Hidden Scripture Pavilion with a gloomy face and appeared in the Yin Yang Valley.

Halfway through, he ran into Lei Chuang and Zhao Wugui, who he hated very much. The two of them had just come out of the deacon's courtyard, and when they saw Wu Yan, they sneered a few times disdainfully, and then went to the Chuangong courtyard by themselves.

Wu Yan walked out of the Yin Yang Valley with an expressionless face, and then stepped on the banana leaf boat magic weapon, left the Xiuzhen Gate directly, and flew towards the Huofeng Mountain Fang City again.

From Qian Yan, Wu Yan finally understood where the problem was.

It turned out that there was a change in the Gu Dan Fang compared with the Dan Fang used today, that is, in addition to various alternative raw materials, a new material needed to be added - the Demon Beast Neidan with the same attributes.

The inner pill of the demon beast is a very commonly used neutralizing auxiliary material for refining pills in the immortal cultivation realm today. The first-level demon beast does not have an inner pill, and the demon beast will only form an inner pill in the body when it reaches the second level.

The strength of an ordinary first-level demon beast is equivalent to that of a monk at about the twelfth layer of the Qi refining period, but because there is no inner pill, it can only use some low-level spells, and its strength cannot be compared with a monk at the twelfth layer of Qi refining at all. The second-level demon beast began to gradually awaken its natal talent spell because of the inner dan, so its strength gradually became stronger, which is equivalent to a monk in the early stage of foundation building. However, if the cultivators in the early stage of foundation building did not have powerful magic weapons, and the exercises they cultivated were also ordinary exercises, they would definitely not be able to defeat the second-level demon beasts. After all, the physique of demon beasts itself is very strong, and ordinary magic weapons and spells can't even break through their outer skin shells, so how can they be injured.

What made Wu Yan feel extremely depressed was that to refine the Zhuji Dan that was suitable for him to take, he had to have the Inner Dan of the Five Elements Attribute Demon Beast.

Along the way, Wu Yan was thinking about this matter while letting go of his divine sense and paying attention to his surroundings. Sure enough, when he was about to arrive in Huofeng Shanfang City, he finally noticed that someone was following him behind.

There were three people who followed him, and the three of them didn't know what their idea was, so they didn't show up to intercept him, but let him go to Huofeng Shanfang City.

Wu Yan secretly sneered in his heart, and did not look like he had been discovered, but swaggered straight to Huofeng Shanfang City.

This time when he entered Huofeng Mountain Fang City, he did not change his appearance, and he was wearing the clothes of a disciple of the Xiuzhen Sect, so after entering the Fang City, many monks saw him and were very polite. It seems that Xiuzhenmen's fame in this area is still quite large.

Wu Yan turned around Huofeng Shanfang City, even the largest Treasure Pavilion also went around, and visited the Danqi Pavilion again, but unfortunately, he didn't even touch a demon beast with five elements attributes.

Although there are a large number of demon beasts on the side of the Zhen Evil Valley, there are a large number of demon beast materials in the Huofeng Mountain Fang City, but it is a pity that there is no Neidan of the Five Elements Demon Beasts. There are many other demon beast inner pills of various attributes, especially the inner pills of the two attributes of earth and fire are the most.

Out of Huofengshanfang City, Wu Yan's face was gloomy. After he stepped on the banana leaf boat magic weapon and flew out for dozens of miles, the three guys actually followed behind.

Wu Yan, who was in a depressed mood, after thinking about it, showed a cold smile, sacrificed the Molin sword, changed the banana leaf boat magic weapon, and galloped all the way towards the opposite west of the Xiuzhen Gate.

After cultivating the first layer of the Divine Cultivation Technique, Wu Yanyun made the Mo Lin Sword as he wished. This top-level magic weapon is worthy of being a treasure refined by Elder Jin Renfeng, and it can have both flying effects, and the speed of flight is twice that of ordinary top-level flying magic weapons. The only drawback is that when this magic weapon flies, it consumes a lot more mana than a specialized top-tier flying magic weapon.

Wu Yan patted the storage bag, took out two Qi Replenishing Pills and threw them into his mouth, and while controlling the Zhì Mo Lin Sword to fly at a uniform speed, he silently absorbed the spiritual power in the Qi Replenishing Pill and restored the mana consumed.

Half a day later, the three guys who were following him behind had been dumped by him.

Wu Yan flew while looking at the terrain below. Half an hour later, his expression moved, and he landed in a narrow terrain in a Heavenly Canyon with a narrow terrain.

After walking around the canyon twice, Wu Yan walked to a thousand-foot high cliff at the end of the canyon with a blank face, touched his chin and looked at the steep black mountain rocks on both sides and opposite, thinking about something.

After a moment of silence, he moved. First, he used the Molin Sword to pierce large and dense thumb-sized holes in the black mountain rocks on three sides, and then stuffed small black things into the small holes one by one.

After doing this, he took out a small leather bag from the storage bag, grabbed some green soil from it, mixed it with the black-brown soil under the cliff, stirred it with muddy water, and then bit the tip of his tongue, spurting out a large ball of essence blood in the muddy soil, stirring it well, and then evenly smeared it on the cliffs and rocks on three sides.

After doing this, Wu Yan walked to a big rock under the opposite cliff, sat down cross-legged against the rock wall, closed his eyes and meditated and cultivated.
