Refining the Yin-Yang Mystic Dragon Pill, Qinglin was terrified.

After making all the arrangements, Shen Wen decided to temporarily stay in Stone Desert City.

On one hand, he was waiting for news from the Mo Tie Mercenary Group regarding their search for the strange flame.

On the other hand, he was preparing to refine the Yin-Yang Mysterious Dragon Pill, which he had planned for a long time.

Refining a seventh-grade pill is not easy.

The process is complex, and the heaven and earth energy it draws can easily attract prying eyes, but in a remote place like Stone Desert City, the risk is controllable.

Xiao Ding and his brother arranged the quietest and most spacious independent courtyard for Shen Wen and the other two, strictly forbidding anyone from disturbing them.

Inside the secret chamber, Shen Wen sat cross-legged, adjusting his state.

Cao Ying and Dan Chen sat on either side, holding their breath, their beautiful eyes filled with anticipation and seriousness.

Being able to personally observe the refinement of a seventh-grade pill was an extremely valuable experience for Alchemists of their level.

Qing Lin also stood behind the two women with a curious expression.

"The Yin-Yang Mysterious Dragon Pill, this pill was researched by Venerable Yao. He left a pill formula in the Pill Tower. This pill has the miraculous effect of breaking through and then establishing oneself. The key to refining this pill lies in taming and fusing the residual dragon soul and power within the dragon-type magical core."

The key to refining this pill lies in taming and fusing the residual dragon soul and power within the dragon-type magical core.

Preparations were complete.

Shen Wen's eyes narrowed, and with his palm facing upwards, a dark purple medicine cauldron appeared.

Although not as good as the heaven burning cauldron, it was still a top-grade one, and though not on the Heaven Cauldron List, it was still an excellent medicine cauldron.

He flicked his finger, and a wisp of Myriad Spirit Beast Flame surged into the medicine cauldron. The flames churned, and the temperature instantly rose, yet it was astonishingly stable.

One by one, medicinal ingredients were orderly thrown into the cauldron by Shen Wen, rapidly turning into pure medicinal liquid or powder under his precise soul control and flame temperature.

The entire process flowed smoothly, making Cao Ying's beautiful eyes sparkle repeatedly, and Dan Chen also felt deep admiration.

Shen Wen's control over the heat and his grasp of the timing for medicinal property fusion far surpassed that of an ordinary Seventh-Rank Alchemist.

Dan Chen wanted to exchange thoughts with Cao Ying, but feared disturbing Shen Wen, so she could only suppress the surging thoughts in her heart.

She focused intently on Shen Wen.

And Qing Lin's small face was even slightly red. Shen Wen was already truly handsome, and with this serious expression,

it was like a heavy hammer directly striking Qing Lin's heart, but she quickly suppressed this feeling.

After all the auxiliary medicinal ingredients were processed, Shen Wen's expression became slightly solemn, and he took out one of the seventh-tier dragon-type magical cores obtained from the Luo family.

This magical core was dark gold throughout, with natural dragon patterns on its surface, subtly emitting a heart-palpitating pressure.

"It's about to begin," Shen Wen murmured, then threw the magical core into the medicine cauldron.

The flames instantly enveloped the magical core, beginning to refine it.

Initially, it was quite stable, but as the refinement deepened, the residual beast will and vast energy within the magical core were completely activated!

"Roar—!"

A dragon's roar, as if from ancient times, suddenly erupted from the medicine cauldron, shaking the entire secret chamber with a buzzing sound.

Immediately after, an incomparably violent energy burst forth, actually forming a blurry dark-golden dragon-shaped phantom within the cauldron!

The dragon phantom roared, frantically impacting the cauldron walls and flames, trying to break free from its shackles. Its ferocious aura instantly made Cao Ying and Dan Chen's faces turn pale.

'Not good...'

Cao Ying inwardly sighed, this residual power made even her current soul realm feel terrible.

A seventh-tier magical core, equivalent to a Dou Zong, even if it had been dead for a long time, the will and power contained within it were by no means easy to deal with!

This was the greatest difficulty in refining the Yin-Yang Mysterious Dragon Pill!

Not to mention, the magical core City Lord Luo Cheng gave was of extremely high quality to compensate, which resulted in very high residual power.

Dan Chen's eyes also showed a hint of worry. If refining this type of pill caused a backlash, it could very likely affect Shen Wen himself.

Qing Lin's small face was even paler.

'Is alchemy such a dangerous thing?'

"Hmph! A wisp of a remnant soul dares to be presumptuous!"

Shen Wen was well prepared. He snorted coldly, and the Azure Heaven Dragon Transformation Art within him instantly circulated.

A purer dragon's might emanated from his body, and the Azure Dragon Skin faintly glowed.

At the same time.

He controlled the power of the Flame Ancestral Symbol.

The color of the Myriad Spirit Beast Flame deepened even further, forming a huge net of fire that enveloped the dragon soul.

The dragon soul, sensing the supreme dragon's might from the Azure Heaven Dragon Transformation Art on Shen Wen, instinctively paused, its fierce flames slightly diminishing.

Seizing this opportunity, the power of the Flame Ancestral Symbol completely erupted, domineeringly disintegrating the dragon soul's resistance.

Under the dual suppression of flames and dragon's might, the dark-golden dragon phantom let out an unwilling wail, its form gradually becoming illusory.

It was finally forcibly dispersed, transforming into the purest energy, and began to slowly fuse with the other medicinal liquids in the cauldron.

Cao Ying and Dan Chen watched with surging emotions. The might of the dragon soul's backlash just now made their hearts palpitate.

If it were them, they probably wouldn't be able to suppress it so easily.

The flames within the medicine cauldron stabilized significantly. The dark-golden dragon soul had been completely refined, and pure dragon qi was slowly and steadily fusing with the various medicinal liquids, emitting a peculiar fluctuation of intertwined yin and yang.

Shen Wen was fully focused, his soul power like the most precise spiderweb, covering every minute change within the medicine cauldron, not daring to relax in the slightest.

The pill-condensing process of a seventh-grade pill allowed no room for error.

However, at this critical moment.

Qing Lin, who had been quietly standing behind Cao Ying and Dan Chen, suddenly turned exceptionally pale, and her small body trembled slightly.

In her Triple Jade-Green Snake Flower Pupils, three tiny green dots uncontrollably rotated slightly, revealing immense fear and anxiety.

She opened her mouth, seemingly wanting to say something.

But she was afraid of disturbing Shen Wen, who was refining the pill.

She could only look helplessly at Cao Ying and Dan Chen, her small hands clutching her clothes tightly, knuckles white.

Although most of Shen Wen's attention was immersed in alchemy, his spiritual realm soul was exceptionally keen, and he immediately noticed Qing Lin's emotional fluctuations and actions.

He frowned almost imperceptibly. This was a critical period for the pill's fusion.

He couldn't be too distracted, but he still transmitted a gentle yet questioning thought directly into Qing Lin's mind via soul transmission: "Qing Lin, what's wrong?"

Hearing Shen Wen's voice directly in her mind, Qing Lin was startled.

Then, as if she had found her backbone, she quickly whispered: "Ma... Master... I, I feel... over there with Commander Xiao Ding and the others, that is, where the flame is marked on the map... a very, very powerful aura has appeared!"

It's terrifying.

And that aura... is somewhat similar to my bloodline... but it's much, much stronger!"

"Bloodline similar? Extremely powerful?"

Shen Wen's heart sank abruptly.

In the Tagor Desert, who else could fit these two conditions besides Queen Medusa?

Why did she appear at this critical juncture?

Or did the actions of the Mo Tie Mercenary Group also alert her?

Even if Xiao Ding and Xiao Li took the Three-Striped Clear Spirit Pill, they are only Great Dou Masters, leading the mercenary group to search over there.

If they encountered Medusa, it would definitely be a certain death!
