"I have been obsessed with alchemy all my life, and all my achievements are in this art." Lian Cangqiong said with a look of nostalgia, "As my disciple, you must learn this art of alchemy, and you must learn it well, or you will disgrace your master."

"Master, rest assured, I became an alchemy apprentice six years ago. Because I was unable to draw spiritual energy from heaven and earth into my body, I was never able to refine a single pill. However, my understanding of alchemy has reached a high level, enough to qualify me as a ninth-grade alchemist." Ling Xian chuckled.

The alchemist looked at him in surprise and praised, "Not bad, I am really lucky. I did not expect that you not only have amazing talent, but also such extraordinary skills in alchemy. A nine-grade alchemist at the age of fourteen is a rare sight in the whole world."

"Master, you flatter me. Compared to you, who achieved the ninth-grade alchemy realm at the age of thirteen, I am still far behind," Ling Xian said modestly.

"No need to be modest. As long as you are willing to listen to my teachings, I believe you will be able to break through to the fifth rank before you turn twenty. At that time, you will break my record." Lian Cangqiong stroked his beard and said gently, "Now that you have embarked on the path of alchemy, let me ask you, what do you think is the most desired treasure of heaven and earth among people of our generation?"

Ling Xian pondered for a moment and replied, "I think it should be divine fire."

"Indeed, one of the greatest dreams of our generation is to possess a divine fire born of nature. This flame can not only defend against enemies, but more importantly, the pills refined with this divine fire are more effective, of higher quality, and have a much higher success rate, making them worlds apart from ordinary flames. Unfortunately, divine fire is extremely rare, something that can only be encountered by chance, and therefore most alchemists live with this regret for the rest of their lives." Lian Cangqiong looked at Ling Xian and said in a deep voice, "The first gift I want to give you is a divine fire that is naturally born between heaven and earth, called the Burning Evil Divine Flame. It can only grow in the purest and cleanest places, and can only be possessed by people of the utmost sincerity and integrity."

After saying that, he waved his long sleeves, and a ball of silvery-white flame slowly emerged from mid-air. The temperature around him suddenly rose, and the scorching heat seemed to be able to burn the heavens and the earth and incinerate the eight wastelands.

The silvery-white flames rose and leaped, and in addition to their terrifyingly high temperature, they also exuded a pure aura of light.

Ling Xian shuddered, her gaze fixed intently on the ball of silver flame, her breathing slightly rapid.

Burning Evil Divine Flame!

One of the legendary divine fires, this fire not only possesses terrifyingly high temperatures that can burn anything, but also has the magical power to drive away all evil and poison. Cultivators who possess it will be protected from all evil and immune to all poisons. It is a rare treasure that countless alchemists dream of!

"When I obtained the divine fire, you looked just like me." Lian Cangqiong was very satisfied with his drooling expression and chuckled, "My original divine fire was annihilated along with my physical body. This fire was born within the Nine Immortals Diagram, so I'm giving it to you as a gift. With it, I won't worry about you falling into the clutches of evil demons."

"Thank you, Master!"

Ling Xian bowed deeply, feeling the sincerity and care that Dan Xian showed him, which moved him greatly, as he had been orphaned since childhood.

Lian Cangqiong flicked his long sleeves, and a gentle force lifted Ling Xian up, saying, "Don't rush to worship. This is just the first gift. The next gift is even better than the divine fire. Think carefully about what it is."

Is it even worse?

Ling Xian's eyes lit up, and she searched her mind carefully for anything that could be compared to divine fire for an alchemist. Suddenly, a flash of inspiration struck her, and she blurted out, "Could it be..."

The answer was so astonishing that he could hardly believe it.

As if knowing what Ling Xian wanted to say, Dan Xian smiled slightly and said, "That's right, it is indeed a pure heart."

"Truly a loyal heart..."

Ling Xian was utterly shocked. Those who practice alchemy yearn for two things most in their lives: divine fire and a pure heart.

Both are equally precious, and it's difficult to determine which is superior. If a cultivator had to choose between the two, he would definitely choose the former, because divine fire is also very helpful in battle. However, if a pill refiner had to choose, he would undoubtedly choose the latter.

The Elixir Heart is a rare treasure in alchemy, something countless alchemists can only dream of but never attain. It may be obtained when one breaks through in the realm of alchemy, but many alchemists do not obtain any Elixir Heart even when they break through to the first rank.

It could also be formed from a pill that rivals the creation of heaven and earth, but it's not hard to imagine that even a first-grade grandmaster might not be able to refine such a pill.

That's why Ling Xian was so shocked when she heard that Lian Cangqiong was going to give her a core of his soul.

No one knows exactly how many types of Danxin exist, but the seven known types are what alchemists throughout the cultivation world dream of day and night. There's no way around it; their heaven-defying effects are simply too tempting.

For example, the "Danxin" (丹心) technique, which allows one to instantly recall the formula of a pill upon seeing it, is a powerful and intuitive ability. Imagine painstakingly creating a new pill formula, only to have it readily known – how incredible is that?

"Master, do you possess the kind of innate talent to know the formula for a pill just by hearing it?" Ling Xian asked expectantly.

Lian Cangqiong was taken aback, then laughed and scolded, "You wish, kid. I do have the formula for the pill, but unfortunately it disappeared with my physical body. The pill I'm giving you now is the immortal pill I refined when I ascended to heaven. It was formed by chance after being struck by the divine lightning of the nine heavens and infused with primordial purple energy. I have never used it and have kept it until now."

He raised his right hand, and a pill shimmering with seven-colored light appeared in his palm. It transformed into a small dragon swimming, then into a young tiger running, and finally slowly condensed into a miniature heart. A strange fragrance wafted out, beautiful and wondrous.

"So this is what the Danxin looks like." Ling Xian was surprised. He took a deep breath of the Danxin fragrance and felt completely comfortable and refreshed, as if he were about to ascend to heaven in the next moment.

"Master, what kind of loyal heart is this?"

"This heart of crimson is named 'Knowing All Herbs'," the Cinnamon Immortal replied.

Ling Xian was overjoyed. The "Complete Knowledge of Herbs" was the most mysterious of the seven types of pills. Its effect was to enable the owner to understand all the rare and precious herbs in the world. As long as one saw a herb, its medicinal effects, pharmacology, age, etc. would automatically appear in one's mind and be remembered forever.

Moreover, alchemists who are knowledgeable about all kinds of herbs can not only refine pills faster and with a higher success rate, but they will also often have flashes of inspiration. They can freely combine and mix thousands of rare and precious herbs in their minds, and easily create new pill formulas with more powerful effects based on the original formulas!

While not as miraculous as knowing the formula for alchemy, it is undoubtedly the best alchemical heart for beginners in alchemy!

"Judging from your appearance, you seem to understand this kind of 'heart of loyalty,' so there's no need for me to say more. Come, let me melt it into your heart and help you refine the divine fire." Lian Cangqiong held the heart of loyalty in his right hand and the divine fire in his left, and then they slowly collided in mid-air.

A miraculous scene unfolded.

The blazing flames of the Burning Evil God can burn anything, but the moment they touched Danxin, they were like a child encountering a favorite toy, slowly enveloping Danxin without harming it in the slightest.

"How could such a powerful divine fire not burn away the heart?" Ling Xian asked, puzzled.

"Is it strange? That's why I dared to let you refine the divine fire right now. The heart is one of the purest things in the world, so the Evil-Burning Divine Flame won't harm it. As long as you inject them into your heart together, you can successfully refine these two supreme treasures of alchemy!" Lian Cangqiong explained.

"I see, I have learned a lot." Ling Xian nodded.

"Sit cross-legged and hold your breath." Lian Cangqiong's expression was solemn. He pointed a finger at Ling Xian's chest, and then his chest suddenly split open, revealing a bright red heart that was slowly beating inside.

"Bang! Bang!"

A strong heartbeat rang out, and Ling Xian stared at the scene in astonishment. He felt no pain or discomfort. However, seeing his chest split open was somewhat unsettling.

"Get your focus back!"

With a sharp shout, Danxian raised the Danxin, which was enveloped in silver flames, and slowly pushed it towards Lingxian's heart.

He then formed a mudra with both hands, and a mysterious and profound soul power filled the entire cave. This power acted like an adhesive, perfectly fusing Ling Xian's heart, Dan Xin, and divine fire together, forming a seamless whole.

"boom!"

Ling Xian suddenly opened his tightly closed eyes, his robes fluttering without wind. After fusing the two treasures of alchemy, his cultivation level broke through the bottleneck in one fell swoop, reaching the peak of the fourth level of Qi Refining. He was only one step away from the fifth level.

Clenching his fists and feeling the surging power within him, Ling Xian couldn't help but grin. He raised his right hand, and a faint silver flame slowly rose.

As this wisp of flame appeared, the temperature inside the small cave suddenly increased. The illusory silver flame cast a slightly distorted and wrinkled reflection in the surrounding space, making it look quite mysterious.

It is the Flame of the Burning Evil God.

"I do envy you a little, kid. Others would spend their whole lives trying to obtain the two treasures of alchemy, but you possess them so easily. If word gets out, I wonder how many people will die of anger," Lian Cangqiong said with emotion.

"It's all thanks to Master's generous gift." Ling Xian's heart was heavy with gratitude.

The venerable old man before him not only helped him break the divine seal, but also gave him two extraordinary gifts: divine fire and a loyal heart. Either one of them was a rare treasure capable of stirring up a bloody storm.

"There's no need for formalities between us, master and disciple." Danxian waved his hand and sighed softly, "If you really want to thank me, then work hard in your cultivation. The same applies to alchemy; you cannot be the slightest bit lax."

"Yes, disciple will keep it in mind." Ling Xian secretly vowed that if he had the ability in the future, he would definitely find a treasure that could allow his master to reshape his physical body.

"Alright, now, I will give you one last thing, which is also the most important thing in my life of refining the heavens!"
