Zhou Zhiruo was accepted as a disciple by the demon lord Bai Suzhen and stayed in the wooden alley to practice with her.

Song Xuan naturally wouldn't stop him, but made a look at his wife, signaling her to practice hard and strive to learn all of Bai Suzhen's skills.

As for him, he left Muren Alley and returned to Wushuang City to begin retreat.

First of all, it is natural to forge your own natal magic weapon.

With a thought, the Xuantie heavy sword floated in mid-air, and Song Xuan opened his mouth to spit out a piece of Dan fire, and began to smelt this magic weapon that had been followed for many years.

Half a month later, the Xuantie heavy sword turned into a ball of molten iron and floated in the air, Song Xuan raised his hand and smashed the four strange stones and the Huolin Sword into it as refining materials, and once again spewed out a mouthful of Dan fire, continuing to smelt.

The smelting difficulty of the four strange stones is extremely high, such as the strange stone of Heihan, which was cast for hundreds of years in the plot of Sword Worship Villa before it was made into a peerless sword and a sword of defeat.

Although Song Xuandan's fire was strong, it took more than half a year to remove the impurities in the four strange stones.

After completing this step, Song Xuan took out a bottle of unicorn blood and sprinkled it, and in an instant, he saw a flame like a mushroom cloud rising in the forbidden land, with a tendency to sweep the Eight Desolations.

Fortunately, Song Xuan had already laid out a sword formation with the Holy Spirit Sword Technique around him, so that the flames that had the potential to burn the prairie were compressed little by little, and finally all of them were integrated into the sword embryo.

The sword embryo has been completed, and Song Xuan has continuously slapped out the power of the Five Elements Sword Yuan, imprinting tiny small sword formations on it, and leaving a divine sense imprint in each sword array.

This is the natal magic weapon, which is related to one's own life, the stronger one's own strength in the future, the power of the natal magic weapon will also increase, and to what extent it can be improved in the end, lies in how far the master of the magic weapon can finally go on the road of the avenue!

After doing this, the natal magic weapon was considered to have a prototype, and then he opened his mouth and inhaled, and the magic weapon that vaguely had a trace of flying sword appearance turned into a red rainbow light and submerged into his mouth, and finally stayed in the lower dantian.

The rest of the time is gestation.

The power of the golden pill in the dantian will continuously convey energy to refine this treasure until this treasure is completely formed.

As for how much time it will take, Song Xuan is not easy to estimate, in short, in his opinion, the refining time may need to be calculated in years.

The refining matter came to an end for the time being, and the next year, Xu Fu came to his retreat place with Danding and countless medicinal herbs.

Then, there is the long Dan Dao discussion time.

Alchemy is a matter that requires great experience and knowledge.

First of all, it is necessary to learn pharmacology, to identify various medicinal materials and to know the medicinal properties of each medicinal material, and secondly, to understand the mutual growth and mutual restraint of various medicinal materials.

The complexity of the changes is even more troublesome than Song Xuan's self-created Taixuan Sword Sutra.

After learning pharmacology, it is a variety of knowledge in alchemy, among which the control of heat and the time of baking have strict requirements, and the slightest negligence is the end of the fryer.

Song Xuan communicated with Xu Fu for three years, during which he tried to refine a lot of pills, and of course, he also blew up one Dan furnace after another.

In the end, in Wushuang City, there was even a Dan furnace industry chain, if nothing else, it was really Song Dagongzi's demand for Dan furnace was too great, so big that he single-handedly drove the prosperity of an entire industry.

In the fourth year, Xu Fu left Wushuang City, and he thought that Song Xuan had already preliminarily stepped into the Dan Dao Road, and he had nothing to teach in the future, so he had to explore it himself.

Song Xuan expressed his gratitude to Xu Fu for teaching his alchemy experience in the past few years, and sealed a wisp of curse power into a scroll, which was regarded as a thank you gift.

In this regard, Xu Fu felt a little flattered and left ecstatically with the scroll.

In the following time, while Song Xuan was studying the Dan Dao, he took blood from the fire qilin from time to time to practice, and his life was very fulfilling.

In the tenth year, Zhou Zhiru returned from Muren Alley, and returned to the album space after a warm encounter with the eldest prince of Song.

As for whether the six major demon crossings she learned from the demon lord Bai Suzhen would be passed on to Liu Qinglian and Xiao Zhao, Song Xuan did not force it.

In the twelfth year, in these years, Song Xuan practiced with the blood of the fire unicorn as nourishment all the year round, so that the power of the fire attribute in the Five Elements Golden Pill was cultivated to the state of perfection.

With the operation of the Taixuan Sword Sutra, the five elements began to grow together, and the fire attribute sword element was derived from the earth attribute sword element.

In the twenty-fifth year, the earth-attribute sword element was cultivated to perfection and began to derive the metallic sword element.

In the thirty-eighth year, the metallic sword element was completed, and the water attribute sword element was derived.

In the same year, the natal magic weapon that had been nurtured in the dantian for decades was finally completely formed.

On that day, thunder fell from the sky, and the clouds covered hundreds of miles, and countless thundersnakes kept swimming in the thunderclouds, and it was a scene that was about to destroy the world.

Song Xuan just opened his mouth and spit out, and the natal magic weapon turned into the appearance of a flying sword, and the sword slashed out of the void and cracked the sky, and the thunder tribulation disappeared in an instant.

A sword slashed through the thunder, and the flying sword did not stop there, but wandered in the void space for a while, and disappeared into the sky with a bang.

Half an hour later, the natal magic weapon roared back, and the appearance of the flying sword at this time had changed into a golden spear, and the tip of the spear was carrying a huge dragon corpse, and in the frightened and inexplicable worship of countless people in Wushuang City, he returned to the place where Song Xuan retreated.

The natal magic weapon was formed, and in the first battle, under the control of Song Xuan's divine sense, the divine dragon of the Fengyun world was picked.

I have to say that the combat power of the divine beasts in this world is really low-end, but it is undeniable that the divine beasts are all treasures.

Song Xuan first took out the dragon yuan, and then extracted the dragon blood left in the dragon corpse for preservation, and then began to cramp and peel the skin.

Long Yuan and dragon blood are excellent alchemy materials, and Song Xuan is ready to keep them for alchemy in the future.

The energy required to break through from the Jindan stage to the Yuan Infant stage, from the Five Elements Jindan to the Five Elements Sword Infant, Song Xuan once estimated, even if the fire qilin was drawn into the qilin dry, it was far from enough.

This is also the main reason why he turned to the Imperial Envoy Flying Sword to kill the Divine Dragon.

As for the dragon tendon and dragon skin, he was going to refine a well-fitting Dao robe for himself, as an immortal cultivator, he didn't even have a decent defensive magic robe, which was too shabby. @*~~

.......

In the seventieth year of the retreat, the Five Elements Golden Pill was completely completed, and in the same year, Song Xuan placed high hopes on it, and the pill refined with Dragon Yuan and Dragon Blood and various precious medicinal materials was successfully baked.

This pill was named the Five Elements Condensing Infant Pill by Song Xuan, and there were twelve pills in a furnace, which took nearly 30 years to completely become a pill.

"There is no nail in the mountains, and I don't know the ..... of the year"

Pinching the elixir, Song Xuan couldn't help but sigh with emotion, the path of the Immortal Dao is really a cultivation path that needs to be honed by years.

When the words fell, he opened his mouth and inhaled, and he swallowed all the twelve pills into his stomach, and began to refine the medicinal properties in them, accumulating energy to prepare for the final breakthrough.

This breakthrough is another 20 years ......
