The originally dilapidated cold stone wall has completely disappeared, and a portal appears in front of Yun Yi and Heifeng.

The portal is not big and there is light inside. Although the light is very weak, in such a dark cave, the faint light is extremely conspicuous.

Yun Yi held his breath, his eyes were extremely bright, and his expression was a little excited.

He knew that Heifeng did not lie to him. This was the treasure that Heifeng mentioned, which was the treasure left by a master of the Spirit King. Such a treasure is definitely priceless. If it was spread, not to mention the small Red Moon City, the entire Xuanzhou would be shocked.

That is the treasure left by the Spirit King master. There is no spiritual king in the entire Xuanzhou. The powerful king, even the entire Eastern Wilderness, is one of the few existences.

Whoosh!

Without saying hello, Heifeng turned into a black shadow and entered the door.

Yun Yi dared to slow down half a beat and immediately took a big strode.

Although it has only been in contact for less than a day, Yun Yi has already experienced this black cat's character. If he is slower, he may have to follow the black cat's butt to eat dust, and he can't even catch the hair.

Grass……

Before Yun Yi could walk into the door, he heard the terrifying sound of the black wind.

Behind the portal is a secret room, which is not big and is the size of a house.

Yun Yi saw a black shadow spinning like a stream of light, searching for things everywhere.

But this secret room was empty, and nothing was left except for some decaying and damp air.

"I'm so mama, the dignified Spirit King, even the Five Days of Lihuo Array was set up, but there was not even a hair inside. What the hell is it? It's so angering to death, and it's so angry to death."

Heifeng danced and gritted his teeth. Obviously, the situation in this secret room was completely different from what he imagined. This made Heifeng, who had been waiting for more than half a month, not furious.

“There is a small box there.”

Yun Yi's eyes fell in the corner of the secret room, where there was a box covered with dust. If you didn't look carefully, you wouldn't notice it at all.

Whoosh...

Before Yun Yi finished speaking, the black wind rushed over like lightning.

When Yun Yi walked over, the box had been opened with a loud bang from the black wind.

A dazzling light of fire suddenly rushed out of the box, and the thorns of Heifeng and Yun Yi couldn't help but close their eyes.

After a while, Yun Yi and Hei Feng looked at the box at the same time, and saw a golden book and a light yellow talisman in the box. There was nothing else besides that.

According to Yun Yi and Hei Feng's imagination at the beginning, the treasures left by a spirit king were at least a large number of spirit stones, with endless treasures of heaven and earth, and countless top-quality elixirs.

Unfortunately, there is nothing here, only a book and a talisman in the box.

"Look at what book is this?"

Black Wind said.

Yun Yi nodded and took the book from the box. The book didn't look very thick, only the thickness of his little finger. However, when Yun Yi picked it up, his hand sank and his body leaned forward slightly.

“Very heavy.”

Yun Yi's face changed slightly. I don't know what kind of material this small book is actually worth a thousand pounds. It would be unimaginable if I hadn't held it in my hand.

Yun Yi calmed his arm and pulled the book closer. Four big words were engraved on the golden book cover: Hunyuan Alchemy!

"Huanyuan Dan Sutra, I'm so fucked. This is the Huanyuan Dan Sutra created by Huanyuan Dan Zu himself. It actually appeared in such a bird's place. How could this be possible?"

Heifeng staggered and almost lay on the ground. His bright eyes stared at the Hunyuan Dan Sutra in Yun Yi's hand, and the shock on his face had reached an unparalleled level.

"Who is Hunyuan Danzu? Is it very powerful?"

Yun Yi asked.

"I'm a little bit, can you remove the word "Do"? But they are all very ancient characters, and you don't need to know that level of existence for the time being. You kid have obtained a unique fortune today. The Hunyuan Pill Sutra records countless elixir recipes and countless elixirs in the world. This elixir alone is the supreme treasure and the existence that countless alchemy masters dream of. With this elixir, you kid will definitely be a powerful figure in the alchemy world in the future."

Black Wind said.

"Alliance master? What do you mean, can I become an alchemist?"

Yun Yi asked curiously, and he also knew about the alchemist. This is an extremely sacred profession in the Lingtian Continent. Because of the rare alchemist and the demand for elixirs by spiritual cultivation, the status of alchemist has greatly increased. An alchemist, no matter where he goes, will be regarded as a guest of honor and respected and loved.

But Yun Yi never thought that he could become an alchemist, and he didn't know what conditions it would take to become an alchemist.

After hearing Yun Yi's words, Heifeng looked at Yun Yi blankly, as if he had seen something rare.

"Why are you watching me like that?"

Yun Yi frowned.

"Don't tell me, you don't know that you are an alchemist?"

Black Wind's eyes were wide open.

"I am an alchemist? Why hasn't anyone ever told me?"

Yun Yi was slightly stunned.

"You really don't know?"

Hei Feng saw that Yun Yi was not like a joke, so he couldn't help asking again.

"I really don't know."

Yun Yi spread his hands and said that he was helpless. He came from a small place like Qizhou. How could there be an alchemist in that place? What he knew was too limited.

"Tsk tsk, it's a big waste. Since you met Master Mao, Master Mao will tell you. If you want to become an alchemist, you must meet two conditions: one is the fire spirit body and the other is the power of the soul. However, not every fire spirit body can become an alchemist. Every alchemist is born. This requires another important condition, the power of the soul."

Hei Feng glanced at Yun Yi and saw that Yun Yi was serious about listening, so he continued: "The so-called soul is the origin of human beings. Everyone has a soul, but the soul is hidden in the human body, illusory and unpredictable. The stronger the cultivation, the stronger the soul is, the more sensitive the perception is, but the perception is also illusory, unable to grasp or touch. In this world, there is a kind of person who can naturally produce a kind of soul power. The so-called soul power means to display the power of the soul in a substantial form and release it in the body. This power is different from spiritual power and is not suitable for fighting, but can exert perception to the extreme."

"In other words, ordinary people cannot generate soul power and release it from their bodies. Even people born with soul power may not necessarily have fire spirits. People with fire spirits may not necessarily release soul power. The conditions for alchemists are to take into account both, which is also the reason why alchemists are so rare."

"You kid not only has a unique fire spirit body, but also the red lotus karma fire of the King of Ten Thousand Fires. When you watched the Five Days of Fire Array, your soul power was released, so you are fully qualified to become an alchemist."
