With the history of the development of alchemy, more things have been added to the alchemy itself.

It's getting more and more complex.

However, on the contrary, because of the inheritance between master and apprentice between alchemists, from time to time due to disasters and accidents, the inheritance has been broken, and the essence of alchemy at the beginning has gradually disappeared in the historical river of inheritance.

Now that piece of patina gives Zhang Qingyuan only a relatively basic, incomplete inheritance of ancient alchemy.

But for Zhang Qingyuan,

The significance of this in itself is unprecedented.

Because this not only made Zhang Qingyuan see the beginning of alchemy, but also realized that alchemy was the essence of heaven and earth at the beginning, and the concept of combining the five elements of yin and yang creation became the key to open the door to the core of alchemy.

The most important thing is that this ancient alchemy technique is of great significance to Zhang Qingyuan's cultivation of the Desolate Heaven Refining Body Technique.

"After watching it for so many days, I already have more than ninety percent confidence in refining that thing, and the inner door is coming, and it is too late to optimize the plan, so let's start today!"

Take a deep breath.

Zhang Qingyuan groaned, took out the jade bottle containing the 10,000-year-old bell spirit milk, and put it aside.

At the same time, there was a bang, and an alchemy furnace appeared in front of him.

Zhang Qingyuan pondered for a moment, flashed the medicinal materials of his own medicinal liquid in his mind, and after confirming that it was correct, he began to add medicinal materials to the alchemy furnace, and then the true yuan swept and turned into the Yuanyang True Flame, and the raging flames scorched the elixir in the alchemy furnace.

Little by little, the elixir melted, and the temperature in the entire cave began to rise gradually.

Zhang Qingyuan's expression was extremely focused, and his eyes were completely focused on the alchemy furnace.

Time flies by in the process of alchemy.

A month has passed in the blink of an eye.

On this day,

Zhang Qingyuan, who was in front of the alchemy furnace, opened his eyes, the flames in the furnace had already disappeared, and the temperature gradually decreased.

A substance-like fragrance then spreads, filling every corner of the void.

Looking at the crystal clear, glowing fluorescent liquid like chalcedony suspended in the Dan furnace, Zhang Qingyuan felt that his body was like a beggar who had been hungry for three days and three nights, and a crazy desire poured out of his heart.

"It worked!"

Zhang Qingyuan's eyes bloomed with folded brilliance, and he couldn't help but be excited.

"Next, I will use this medicinal liquid to cooperate to complete the introductory cultivation of the Desolate Heaven Refining Body Technique!"

In the following time,

Zhang Qingyuan raced against time and entered the arduous cultivation.

He sat cross-legged on a white jade futon,

Topless.

Through the manipulation of his mind, his divine consciousness used the water control technique to automatically attach the liquid to the bare skin, and a sharp pain like magma scorching poured into his mind, and Zhang Qingyuan's whole body was as red as coals of fire, as if it was burning.

The veins on his forehead burst out.

But he didn't snort, recalled the description of the Desolate Heaven Refining Body Technique, and began to practice.

Every day's practice,

Zhang Qingyuan felt as if he had fallen into a sea of magma, and the terrifying heat seemed to burn him to the ground.

But Zhang Qingyuan knew that it was just an illusion.

The huge medicinal power passed through the skin, merging into the musculoskeletal, and through the guidance of Zhang Qingyuan's alchemy, it was transforming its muscles, bones, flesh and blood little by little.

It's like crushing your whole body and putting it back together.

The practice is extremely difficult.

But again, progress is visible to the naked eye.

Zhang Qingyuan's physique is constantly improving, and every time he has severe pain, it is like a red iron block that has been beaten, and the impurities are discharged, making it more refined.

The whole body is emitting fluorescence like glass, which looks very strange.

Even the breath is a little stronger.

This cultivation of the Desolate Heaven Refining Body Technique, while tempering his own body, is actually tempering his cultivation at the same time!

The body is constantly improving, and the cultivation is also rising, and the five layers of the True Yuan Realm are getting closer and closer.

This is the spiritual power of the Ten Thousand Year Bell Spirit Milk!

While the huge medicinal power was transforming Zhang Qingyuan's body, making his body as close as a glass golden body, the huge spiritual power was also constantly tempering, entering Zhang Qingyuan's body, and turning into an incomparably pure true element.

There is no doubt that once the cultivation of the Desolate Heaven Refining Body Technique is successful,

Then it will also be the time when Zhang Qingyuan will step into the true yuan fivefold!

At that time, his strength will be greatly improved again!

Inside the Cave,

Zhang Qingyuan's momentum continues to grow,

As if some desolate beast was being bred, an extremely oppressive oppression permeated every corner of the void.

......

Another three days passed.

On this day,

When, when, when!

The melodious sound of the three bells spread across the void of countless thousands of miles, and spread to every corner of the entire Yunshui Sect's sphere of influence.

As long as it is within the Yunshui Sect's sphere of influence,

Everywhere, these three bells are heard.

In a trance, people saw the scene of a huge bronze bell oscillating between the white clouds and high mountains, and at the same time, everyone's soul seemed to have been washed.

The world is clear and refreshing!

Is that...... Spiritual Weapon!

The sound traveled thousands of miles, and the area of tens of millions of square miles was oscillated by this sound, washing the soul, and the sound echoed in my mind for a long time.

To be able to do this, only a spiritual weapon can do it!

At this time, all the knowledgeable people were shocked and gasped, even if they had heard it earlier, they couldn't help but be stunned at this time.

Many people even sit directly on the ground, comprehend the Dao sound, and improve their divine sense.

This sound resounds,

There are already such benefits.

I'm afraid that only a Jade Continent overlord like Yunshui Sect can have such a background.

Everybody understands that

It's a show, and it's a deterrent.

And at this moment, Zhang Qingyuan, who was seizing the time to practice the Desolate Heaven Refining Body Technique in the cave, also opened his eyes, and his eyes showed a little helplessness.
