The next day, Lin Xuan used the Heavenly Demon Imitation Technique to change his appearance, came to the Sea Dragon Pavilion as promised, bought the predetermined Perseverance Grass, and everything went well.

When I was in Fang City, I kept hearing monks talking about someone's big gesture yesterday, throwing out thousands of pills of myelin cleansing pills in one go.

This made Lin Xuan remind himself in his heart, he did lack a little consideration yesterday, although he turned the corner to safety, it was really dangerous, even if he had a change of appearance in the future, he couldn't be so reckless.

After leaving Fang City, Lin Xuan fled all the way to the north, according to the collected information, the northern part of Youzhou was sparsely populated, Lin Xuan wanted to find a secret place, refine the best marrow cleansing pill, and impact the foundation building realm.

Three days later, Lin Xuan landed on a barren mountain.

As far as the eye can see, there are poor mountains and bad waters, many fierce beasts, and few people, which is an excellent place for retreat and cultivation.

Lin Xuan showed a satisfied look on his face, and he looked around, and finally picked a cave.

The cave is located on a steep cliff that is impossible for ordinary beasts and mortals to climb except for birds.

Lin Xuan released the flying sword and rested the cave for a while, and soon, a simple cave was opened up by him, and then Lin Xuan took out a talisman from his arms.

This is the last formation talisman, Lin Xuan's face flashed a trace of reluctance, but he still used his spiritual power to sacrifice it out of the gang.

The spiritual power touched the sealing formation, and the burning rune paper turned into a small yin and yang gossip, and then soared rapidly, flying out of the cave, enveloping the entire cave mansion.

Put in place the prohibition. Lin Xuan rested for the night and stayed early the next morning. The physical strength and mana were restored to the best state, and only then did the alchemy begin.

The first is to prepare the raw materials.

Purifying the Purifying Pill is already a breeze for Lin Xuan. Although the upper grade Dan is a little more difficult. But Lin Xuan's current cultivation is no longer what it used to be, and it only took three days to refine a hundred high-grade pills.

Silver moonflowers, flowing fireflies are available, and perseverance grass has also been successfully acquired.

But of course, Lin Xuan would not be reckless, so he started alchemy. After all, it was his first time, and it was strange not to fail.

Lin Xuan first took out the jade tube slip and carefully studied the alchemy technique, except for reading books. He also often flew out of the cave to look for some herbs around and try to do alchemy.

Naturally, there were no natural treasures to be found in this vicinity, and the places that Lin Xuan had refined were all ordinary pills that treated injuries or strengthened the body.

These elixirs are hard to find in the world. But for cultivators. It's not very useful, Lin Xuan is just used to practice.

Graded according to the fairy realm. Alchemists also have several realms, just by refining these garbage pills, they can reach the entry level at most, but the second refining is actually easier than refining the lower grade marrow washing pill, plus he still has perseverance grass to improve the success rate, so Lin Xuan is still very sure. Time is like water, and half a year has passed in a blink of an eye.

In the past six months, although Lin Xuan's realm has not improved, his mana has become more sophisticated, and he also has a certain understanding of alchemy

Early that morning, Lin Xuan decided to start refining the best marrow cleansing pill.

He first took out the small Ding furnace from the storage bracelet, I don't know what metal this thing is made of, the shape is simple, the surface of the Ding furnace is carved with the pattern of the four holy beasts.

Vermilion Bird, Green Dragon, White Tiger, Xuanwu, lifelike, not like a mortal thing at first glance.

Then, Lin Xuan took out several spars and arranged them into a pattern of the Big Dipper.

"From. ”

Lin Xuan threw the Ding Furnace into the air, hugged his hands into a ball, and injected spiritual power into the spars, the patterns of the Big Dipper suddenly lit up, and from each spar, a different pillar of light radiated, colorful and gorgeous, and the most columbian gathered together, holding up the Ding Furnace.

Lin Xuan's expression was solemn, he took the vial placed beside him, threw it into the sky, and then played a trick like a Ding furnace.

A white light flew out from the Ding furnace, and with a bang, the vial exploded into pieces, and the top-grade marrow washing pill inside was sucked into the Ding furnace like a long whale taking water, and then Lin Xuan's sleeve robe was flicked, and the silver moon flower and flowing firefly grass were also added, and the other powder was ground with perseverance grass.

After the raw materials were added, Lin Xuan flipped his hand, and there was already a fiery red talisman in his palm, the talisman of earth and fire, which was specially prepared for the alchemy of low-level cultivators, and flew to the bottom of the Ding Furnace.

Although Lin Xuan had already refined hundreds of furnaces of pills in a row before this, compared to those ordinary pills, it was definitely more difficult to condense the best marrow cleansing pill, and the time it took was not the same.

According to Lin Xuan's speculation, it will take at least seven hundred and forty-nine days, and the slightest mistake in the meantime will lead to the loss of all previous achievements.

And the materials in Lin Xuan's hand no longer allow him to refine the second furnace pill, only succeed, not fail.

Time passed quietly.

A month passed......

In the blink of an eye, it was finally the forty-ninth day.

Looking at the earth furnace surrounded by flames, Lin Xuan sighed lightly, everything went well, fortunately, it was not difficult to refine it for the second time, he was fully prepared, and he added the Perseverance Grass powder that can improve the success rate, it seems that this time the best marrow cleansing pill can be successfully baked.

Although he doesn't have a spiritual root, but with the effect of the best pill that can almost defy the sky, a full hundred, if he can't build a foundation successfully, then there is no heavenly reason!

A smile appeared on Lin Xuan's face, but at this moment, a slight collision sound came into his ears.

Lin Xuan raised his eyebrows, and his face became gloomy.

Coincidentally, someone came to disturb at this time, and the voice just now was an alarm issued after the formation was touched.

Lin Xuan played a few tricks, first stabilized the situation of the Ding Furnace and the Earth Fire, and then released his divine sense, only to see an immortal cultivator about forty years old appear at the entrance of the cave.

The great consummation of the agile period.

Seeing this person's cultivation clearly, Lin Xuan's face softened slightly, as long as he was not a master above the foundation building period, due to the large amount of ginseng essence consumed, the mana was pure, compared with the monks of the same level, Lin Xuan's strength was obviously higher.

After a little contemplation, Lin Xuan used his spiritual power and passed on a sentence: "Fellow Daoist, stop, this is my cave mansion, Yu doesn't like people to disturb me, please go back!"

Tan Ming listened to the transmission, looked at the prohibition in front of him, was a little surprised, and hesitated: "It's a guest from afar, why should Taoist friends refuse people thousands of miles away, since the meeting is fate, why don't you let me go in and sit." ”

The other party's words seemed to be very polite, but when Lin Xuan heard it, he sneered, the strong in the cultivation realm are respected, whether it is the right path or the evil demon, killing people and robbing treasures is just commonplace.

When he was in Piaoyun Valley, he heard from his senior brother and elders that cultivators usually have to find a place where no one is in retreat, because when practicing the exercises, once they are disturbed, it is easy to go mad.

This guy's words are just a temptation, and once he is sure that his practice is at a critical juncture, he will take advantage of it......

A wisp of gloom flashed on Lin Xuan's face, since the other party had bad intentions, there was no need to bother with tongues, the first strike was strong, and the second attack was harmed, Lin Xuan took a breath, and several magic tricks came out of his hand and hit the ban.

After Tan Ming transmitted the sound, he waited for a long time, but he didn't hear an answer, and a trace of joy flashed on his face, it seemed that he had hit a lot of luck today and met a cultivator who was in retreat.

Looking at the situation, the other party's cultivation of the exercises happened to be at a critical juncture, and it was inconvenient to act.

Although he already had the idea of killing people and robbing treasures in his heart, this monk named Tan Ming was still quite careful, the other party could lay out a formation in front of the cave, and his strength was definitely not weak, and nine times out of ten he was a cultivator in the foundation building period.

But this speculation did not dispel his greed, but he was even more pleased, the higher the other party's skill, the more rich his net worth, anyway, he is inconvenient to act, what are you afraid of?

Patted the storage bag, and a spirit weapon in the shape of a short spear was sacrificed.

Tan Ming was about to make a move, but the sky suddenly darkened, it was daytime, but he couldn't see his five fingers, and above the canopy, a huge gossip appeared.

"Hallucination?" Tan Ming's heart froze, knowing that he had fallen into the formation laid by the other party, and unexpectedly, it also made him surprised and suspicious.

Isn't the other party unable to do it, how can he still urge the formation, is it wrong to miscalculate?

His eyes rolled, and a cunning color flashed: "What are you doing, Daoyou, there is no malice in the bottom!"

"No malice?"

Lin Xuan's face was full of ridicule, when he was a three-year-old child, he ignored the other party's explanation, and smashed a red light into the prohibition.

Suddenly, the gossip pattern in the canopy began to rotate, and the speed became faster and faster, and pieces of fire rain poured out from it.

Tan Ming was startled, and hurriedly activated the defensive cover, and then sacrificed a treasure in the shape of a flower cloth, which was only the size of a palm, but after being injected with spiritual power, it immediately soared to several zhang, floating above Tan Ming's head.

"Defensive Spirit Weapon?" Although Lin Xuan was in the depths of the cave, he used his divine sense to see the situation outside clearly.
