As long as there is the first successful experience, Xu Mu already knows the heat when Bigu Lingdao is used in medicine.

In this way, it's simple.

"Poof!" The Nine Shadows Fire rose, and another Bigu Spirit Rice was thrown into the medicine tripod by Xu Mu.

Under his perfect flame control, the temperature in the furnace was contained to a proper position.

Not surprisingly, this time with the medicine, he succeeded again.

Under the scorching of the Nine Shades of Fire, the Bigu Spirit Rice exudes an attractive fragrance.

The shadow of Bigu Lingdao was reflected in his pupils, Xu Mu's current state of mind, there was no sadness or joy, he didn't want to fall short because of another emotional fluctuation.

The time of taking the medicine is particular and depends on the quality of the elixir.

For a rudimentary-grade elixir like Bigu Spirit Rice, half a cup of tea time is enough.

As soon as the time came, Xu Mu waved his palm, and the top cover of the medicine tripod was held in his hand, and then the Bigu spirit rice was closed in the medicine tripod.

Officially entered the second stage, brewing.

Controlling the Danhuo will completely stimulate the medicinal properties of Bigu Spirit Rice in the medicine tripod.

The purpose of sealing the medicine tripod is to prevent the loss and overflow of the medicinal properties.

Moreover, the second stage, the control of flames, also has strict requirements.

But this is not difficult for Xu Mu.

His eyes slowly closed, his divine consciousness spread, and he sank into the medicine tripod in front of him, and the situation of the grain spirit rice in the ding furnace was fully seen.

In the completely sealed Yaoding space, the Nine Shadows Flame was refining the Bigu Spirit Rice.

The medicinal properties hidden in the elixir are stimulated and brewed at high temperatures.

This is the most time-consuming of the four stages of refining the elixir, and it is also the one that tests the alchemist's control over the Danhuo.

If it is used too little, it will lead to incomplete stimulation of the elixir, and when it finally becomes a pill, it is directly related to the quality of the elixir.

It took too much time, and the medicinal power of Bigu Ling Rice was over-evaporated by Danhuo.

The same affects the potency of the drug.

......

Time, in the process of Xu Mu's concentration and refining medicine, passed quietly.

With the Nine Ghost Flames as the Dan Fire, a lot of spiritual power is consumed, and even with Xu Mu's excellent recovery speed, it still can't keep up with what he consumes.

Basically, every three hours, Xu Mu had to stop and recover the spiritual power consumed in his body.

With each time his spiritual power was exhausted, to replenish, the spiritual power in his cyclone became more and more refined.

The peak realm of the Eight Heavens of Imperial Qi is also becoming more and more stable.

This can be regarded as an unexpected joy in the process of alchemy.

Three days later, Xu Mu's 500 Bigu Spiritual Rice had been exhausted.

Looking at the thirteen Bigu Pills lying quietly in the jade bottle, a few black lines appeared on Xu Mu's brain.

A full 500 Bigu Spirit Rice, let a medicine boy refine it, at least more than 100 Bigu Dan can be refined.

And he only succeeded in thirteen.

The rest, even though it is Cheng Dan, has less than three percent of the medicinal power, and there is no difference from the waste pill.

Five hundred Bigu spiritual rice is almost worth fifty spirit stones, and Bigu Dan, on the market, is only one spirit stone.

In other words, Xu Mu worked hard for three days, not to mention, and lost thirty-seven spirit stones.

"I'm really ugly enough!"

Fiddling with the more than ten Bigu Pills in the bottle with his fingers, Xu Mu looked at the pitted surface of the Bigu Pill he had refined, and a touch of self-deprecation appeared on the corner of his mouth.

These thirteen pills are not only ugly in appearance, but also barely reach 30% in medicinal properties.

The best one of Bigu Dan is only forty percent of its medicinal properties.

Even if you take it out and sell it, it probably won't be noticed because it's too ugly.

"I don't plan to sell it anyway!"

Picking up a Bigu Dan and throwing it into his mouth, Xu Mu's mouth chewed slowly, and in a vague tone, he said to himself: "I'll eat it myself!"

Today, there are still 300 petrified grasses left in his storage bag.

Because of the focus on refining Bigu Dan, the petrified grass has not moved.

The pill made from petrified grass is called Shifu Dan.

Like Bigu Dan, it is an unqualified pill that is suitable for medicine children to refine.

After taking the Stone Skin Pill, the surface of the body will be as hard as a rock, and in the early stage of the Qi Realm, the defense is not bad, and it has a strength increase for the user.

Of course, the little defense and strength increase of the Stone Skin Pill was a bit of a chicken rib for the monks in the middle and late stages of the Imperial Qi Dynasty.

Therefore, it can only be regarded as an elixir that is not included in the product.

Moreover, almost all of the pills that are not included in the product are single, and there will be no mixing and refining of several pills.

You don't need any Danfang, you can explore and refine it yourself.

Put the medicine pod and the Bigu Dan filled with the entire jade bottle into the storage bag.

Xu Mu stood up and stretched lazily.

Immediately, he glanced at the place where he had stayed for three days, the ashes and the wreckage of the waste pill in that place.

"It's the third day, the spirit stone auction is about to start, and I should go find that little girl!"

The words fell, Xu Mu stomped under his feet, and his figure had already jumped up and rushed in the direction of Lingshi.

Xu Mu was obviously not the only monk rushing towards the Spirit City.

Because today is the day when the auction of the Spirit City opens, with the Spirit City as the center, the sects with a radius of tens of thousands of miles have sent strong people to come.

There is also a large number of loose practices that should not be underestimated.

In the deserted realm on weekdays, when Xu Mu was in a hurry, he actually met several monks.

Of course, out of wariness of each other, even if they happen to meet, no one has to come forward to say hello.

In a few moments, the fog array in front of the Spirit City had already appeared in front of him.

Xu Mu is about to step into it.

"Huh!" a sail spell that pierced the sky burst through the sky, and from far away, it shot all the way, the target was the spirit city shrouded in dense fog.

Xu Mu was attracted by the sharp sound of breaking the air, and with a glance, he happened to see two figures on top of the ship-shaped magic weapon.

One of them was a young man in white, although his appearance was ordinary, but he had a proud face, and his hands were behind his back.

His eyes stared intently at the fog array in front of the spirit city, ignoring the monks around the fog array.

Behind the young man, there stood an old man with a thin face.

In the cloudy eyes, it seems that there is no look, and the face is wooden.

"Imperial Qi Eight Heavens!" Xu Mu muttered to himself while feeling the young man's cultivation.

Seeing that he is only as old as himself, the Eight Heavens Realm of Imperial Qi should also belong to the genius column in the sect he is in.

As for the old man, Xu Mu couldn't see the slightest shade.

However, to be able to possess this precious flying magic weapon, the identity of a teenager should be extremely extraordinary. It is very likely that Lao Tzu is his bodyguard or the identity of his elders.

Just as Xu Mu looked at the two people on the flying magic weapon, the young man in white seemed to feel something.

The arrogant eyes slanted slightly, skimming the figure of Xu Mu below.

Because he was deliberately low-key, Xu Mu's cultivation was always suppressed by him in the Sixth Heaven of Imperial Qi.

With the aura suppressed by the multicolored spirit tree, unless he was a monk who was too much higher than Xu Mu's cultivation, he would not want to see through his true cultivation.

At first glance, the young man only thought that Xu Mu was just a monk of the Sixth Heaven of Imperial Qi.

Coupled with the fact that he himself had a broken arm, it was even more inconspicuous.

"Hmph!" snorted coldly, a trace of disdain flashed in the young man's eyes, and he directly withdrew his gaze at Xu Mu.

Control the flying magic weapon under his feet and rush straight into the fog array.

Not thinking that the inner boy showed contempt, and with the slightest annoyance, Xu Mu touched the tip of his nose with his palm and whispered softly: "Flying magic weapon, it should be very valuable!"

As we all know, if you want to fly through the sky, you must break through the Dharma Body Realm.

Qi Realm monks, if they want to take off into the air, they must use external objects.

Flying magic weapons are the best choice.

However, the flying magic weapon is extremely expensive, almost the same price as a high-grade magic weapon.

Therefore, not everyone can afford to buy a flying magic weapon, and today is the first time Xu Mu has seen the legendary flying magic weapon.

Some eyes looked at the sail magic weapon that disappeared into the thick fog, Xu Mu lowered his head and touched his storage bag, and said secretly: "When you have money in the future, you must buy a flying magic weapon." ”

Who in the world doesn't want to fly in the sky? Wander freely between heaven and earth! Experience the feeling of freedom.

It's a pity that the Dharma Body Realm is a heavenly moat, isolating the path of cultivation for I don't know how many monks.

Before you really break through the Dharma Body Realm, if you want to take off and fly, flying magic weapons are the only option.

With his heart's yearning for flying magic weapons, Xu Mu slowly moved his body and stepped into the fog array.

However, a strange thing happened inadvertently in Xu Mu.

At the moment when Xu Mu's back was completely submerged in the thick fog, where he was standing, the space was distorted, and a vague shadow gradually emerged from nothingness.

A handsome young man with a bright smile that could almost be compared to Xu Mu appeared out of thin air where Xu Mu had just stood.

"The goose plucks its feathers, the thief does not go empty, the little master is empty!" A paper fan spread out in the hand of the young man who appeared in an extremely mysterious way, and in his other hand, he was playing with a jade bottle at random.

Looking closely, it was the result of Xu Mu's refining for three whole days, the jade bottle full of Bigu Dan.

"Judging from my many years of experience in Miaokongkong, this bottle of elixir should be worth a lot of money!" With the joy of the harvest, the self-proclaimed Miaokongkong boy opened the jade bottle with a happy face.

Suddenly, the atmosphere froze, and when he saw the elixir contained in the bottle clearly, his smile stiffened on Miaokong's empty face.

"I'll go to your uncle, I'll be happy for nothing, a bottle of Bigu Dan. And your mother is so ugly!"

"It's really unfavorable for the passing years! This is the Bigu Dan of which sect's Dao Tong Lian, he looks like, don't let me meet you, or I will definitely kill you!"
