When he was in the city, he heard people talking about someone who sold thousands of Essence Purifying Pills.

This made Lin Xuan wake up in his heart. Yesterday, he lacked a little bit of consideration. Although he returned safety, it was also very dangerous. Even if he has a lot of tolerance, he can no longer be so rash.

After leaving the city, Lin Xuan went all the way to the north. According to the collected information, the northern part of You Prefecture was spa.r.s.ely populated. Lin Xuan wanted to find a hidden place, refine the Top Grade Essence Purifying Pill, to break his way through Foundation Establishment.

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

Looking around, surrounded by mountains and rivers, only beasts with no people, the perfect location for closed door cultivation.

Lin Xuan showed a satisfactory look on his face, patrolling around and finally picking a cave.

This cave is above a steep cliff. Apart from flying birds, ordinary beasts and mortals cannot climb at all.

Lin Xuan released his Flying Sword moved toward the cave. Soon, a simple Cave Mansion was formed, Lin Xuan then took a Talisman from his arms.

This is the last Array Talisman, Lin Xuan hesitated slightly, but still circulated his Spiritual Qi, and used it.

Spiritual Qi touched the seal's Formation, and the burning Talisman paper became a small yin and yang symbol, then swiftly soared and flew out of the hole, shrouding the entire Cave Mansion.

After finis.h.i.+ng the formation, Lin Xuan took a rest till the next morning, and let both his physical strength and Spiritual Power returned to their best before he started Alchemy.

The first step is to prepare the raw materials.

Purification of Essence Purifying Pill to Lin Xuan. Is already very familiar. Although the High Grade Pill is a bit harder, Lin Xuan's current cultivation base is no longer the same. It took only three days to refine a 100 high grade Pill.

The Silver Moon Flower has been produced, and the Heart Gra.s.s has also been successfully acquired.

But Lin Xuan certainly didn't take the risk of starting Alchemy. After all, it's his first time, it's not strange to fail.

Lin Xuan first took out a Jade slip and carefully studied Alchemy. In addition to reading, he often flew out of Cave Mansion and looked around for some medicinal herbs for practice.

Naturally, there was no treasures of Heaven and Earth in Lin Xuan's practice. They are all common medicine pills that treat injuries or strengthens their body.

These medicine pills are rare and hard to find, but to cultivators, they are of little use. Lin Xuan only used them to practice.

According to Immortal World's grading, Alchemy is divided into several levels. Refining these trash pills will get them to low grade. However, Double-Refining is actually easier than Refining Low grade Essence Purifying Pills. Plus, there's also the heart gra.s.s to improve his success rate.

Time flowed like water, and it has been half a year since then.

In the past six months, although the depth of Lin Xuan's cultivation has not improved, his Spiritual Qi has become more sophisticated, and has a certain understanding of Alchemy.

It was early in the morning. Lin Xuan decided to start Refining a Top Grade Essence Purifying Pill.

He first took out a little Cauldron from his Storage Ring. The object was made of metal. The shape was simple. The surface of Cauldron was engraved with the pattern of the four holy beasts.

Vermilion Bird, Azure Dragon, White Tiger, Black Tortoise, which looked lifelike, not like anything ordinary at first glance.

Lin Xuan then took out a few pieces of Spirit Stones. Put them into a pattern of the Big Dipper.

"Rise!"

Lin Xuan threw the Cauldron into the air, clenching his hands into a ball. Injecting Spiritual Qi into the Spirit Stones, the pattern of the Big Dipper illuminates. From each Spirit Stone, a different beam of light is emitted, colorful and blinding, and finally gathered together into the Cauldron.

Lin Xuan's expression was dignified, took the vial placed next to him, threw it into the sky, and then used a Secret Art on the Cauldron.

A white light flew out of Cauldron, and with a bang, the vial was blown into pieces. The High Grade Essence Purifying Pill was sucked in by the Cauldron like a whale taking in water, Lin Xuan swept his sleeve, and added in the Silver Moon Flower and firefly gra.s.s, the other ingredients were grounded into powder with the Heart Gra.s.s.

After the raw materials were added, Lin Xuan flipped his hand, and a red-hot Talisman was in his palm. The Earth fire was specially prepared for the Alchemy of Low-Rank cultivators.

Spiritual Qi was injected, Lin Xuan sighed, and the Earth Fire talisman suddenly turned into a red Fireball, flying below the Cauldron.

Although Lin Xuan refined hundreds of furnaces of medicine pills before it, compared to the common medicine pills, the condensation of a Top Grade Essence Purifying Pill is definitely more difficult and the time spent is not the same.

According to Lin Xuan's speculation, it'll take least 7 or 47 days, a slight mistake will lead to failure.

The materials in the hands of Lin Xuan do not allow him to refine a second time, he can only succeed, not fail.

Time pa.s.sed quietly.

A month has pa.s.sed…

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

Looking at Cauldron surrounded by flames, Lin Xuan signed softly and everything went well. Fortunately, Double-Refining is not difficult, he was fully prepared, and he also added the Heart Gra.s.s powder which can improve success rate. It seems that this time the Top Grade Essence Purifying Pill can be successfully refined.

Although I don't have a Spirit Root myself, with a Top grade Pill, I can almost completely defy the Heavens. If I can't succeed in Foundation Establishment, then it's completely unreasonable!

Lin Xuan had a smile on his face, but at this moment, a slight collision sound was heard.

Lin Xuan's brow wrinkled and his complexion was gloomy.

Coincidently, someone was disturbing him at this moment. The voice just now was an alarm issued after Formation was triggered.

Lin Xuan used a few Spiritual Arts, he first stabilized the Cauldron and the Earth fire, and then released his Spiritual Sense, only to see an Immortal Cultivator about forty years old, standing in front of the cave entrance.

Spirit Condensation Stage Great Perfection.

Looking at this person's cultivation base, Lin Xuan complexion is a bit better, as long as it's not Expert at the Foundation Establishment Stage, because of the large amount of essence of ginseng he consumed, his Spiritual Qi is pure, compared with cultivators of the same realm, Lin Xuan's strength is obviously a little higher.

With a little contemplation, Lin Xuan works his Spiritual Sense and pa.s.ses a sentence: "Fellow Daoist stops, this is my own Cave Mansion, I don't like people bothering me, please leave!"

Tan Ming listened to the voice and looked at the formation in front of him. He hesitated slightly. "this guest comes from afar, Fellow Daoist refuses to be with someone from thousand miles away. Meeting each other is fate, why not let me in."

The other party's words seemed very polite, but as Lin Xuan listened, he sneered, in the Immortal World Experts are respected, whether it was the righteous or the demonic way, killing people and stealing treasures, is commonplace.

In Whirlwind Cloud Valley, he heard his Senior Brothers and Elders saying, that when cultivators enter seclusion, they usually look for an unoccupied place, because in cultivation, once disturbed, it is easy for Qi Deviation to happen, if you meet a strange Cultivator, in all likelihood, will be robbed, and people who bully experts in seclusion usually start, by killing, then robbing their treasure.

This guy's words are just a test. Once he's sure that his cultivation is in a critical moment, he will take advantage of it…

Lin Xuan's face flashed a sigh of gloom. Since the other party has no good intentions, there is no need to say anything more. First, he should start with his strongest attack. Lin Xuan took a deep breathe and a few Secret Arts came out, on top of the formation.

Tan Ming waited for some time, hearing no answer, his face could not help but flash a trace of Happiness, it seems like it's his lucky day, he met a cultivator in Closed door meditation.

Looking at the situation, the other party's Cultivation Method is at a critical juncture and it's not convenient to act.

Although there was already thoughts of murder and robbing in the heart, this cultivator called Tan Mingdi, is still very careful, the other party can lay a Formation in front of the Cave Mansion, their strength is certainly not weak, in all likelihood, the Cultivator is of the Foundation Establishment Stage.

However, this speculation has not dispelled his greed, but was even more pleased. The higher the skill of the other side, the more lucrative the net worth. He's not in convenient situation to act anyway, what is he afraid of?

He patted his storage bag, and a short gun like Spirit Tool was taken out.

Tan Ming was about to take action, but the sky suddenly dimmed, obviously it's daytime, but he can't see his fingers, and there is a huge yin-yang symbol above the sky.

"An illusion?" Tan Ming was stunned, knowing that he had fallen into the formation of the other party. Under an accident, he was also surprised and suspicious.

Isn't the other party unable to do anything. How can we still use the Formation? Did he estimate wrongly?

His turned his eyes, and it flashed with slyness: "Fellow Daoist What is this, i don't have any bad intentions"

"no offence?"

Lin Xuan's face was full of ridicule. He isn't a three-year-old child, he ignored the other's explanation and threw a red light into the formation.

Suddenly, the yin-yang pattern in the sky began to spin, and it's speed was getting faster and faster, and pieces of fire and rain poured out from the inside.

Tan Ming was shocked, quickly used a defensive barrier, he then too out a piece of cloth. The cloth was only palm-sized. After being injected with Spiritual Qi, it immediately rose to a few feet, floating over Tan Ming's head.

"A defensive Spirit Tool?" Lin Xuan is deep in the Cave Mansion, but by using Spiritual Sense, it makes the outside situation clear.
