Yun Yi's breathing was a little rapid. He never thought that he could one day become an alchemist and an alchemist, and he knew extremely well.

He devoted himself to practicing, pursuing improvement of his realm, and was eager to find treasures to extend his life and to heal his grandfather's injuries, but he never knew that he had the unique conditions for an alchemist.

He had no choice but to be excited about this situation. He knew very well that if he could become an alchemist, he could refine the pills he needed, or even pills used to extend his life.

The Hunyuan Dan Sutra in his hand seemed to have become as heavy as ten thousand pounds, which was his position in Yun Yi's heart.

This records the method of refining countless elixirs in the world. His and his grandfather’s predicament may be able to find a breakthrough in this elixir.

"I didn't expect that I was qualified to become an alchemist. However, I have never tried alchemy and I don't know where to start."

Yun Yidao.

"I'm so mad, are you stupid? With this Hunyuan Alchemy Sutra, do you still need someone else to teach you how to get it? If you can get one percent of the essence of this Alchemy Sutra, you can walk sideways in the alchemy world."

Hei Feng said with disgust. Hei Feng obviously pursued the Hunyuan Alchemy.

"Heifeng, why do you know everything? Are you still an alchemist?"

Yun Yi looked at Heifeng curiously. This black cat was so magical. He had a vicious vision, had a unique treasure hunting ability, and was proficient in the art of formations. He even knew the origin of the Hunyuan Pill Sutra and the Red Lotus Karma Fire. Now he was very good at alchemy, as if there was nothing he didn't know about this world.

"Hmph! Is there anything else in this world that Master Mao doesn't know? Boy, there are so many things you have to learn from Master Mao in the future. However, Master Mao is not an alchemist, and I don't have the qualifications to be an alchemist, but the necessary conditions for an alchemist, as well as the legendary Hunyuan Alchemy Sutra. Master Mao still knows. Anyway, you kid, you are developed this time."

Hei Feng snorted, obviously he seemed to be worried about not getting any benefits from him. After all, he discovered this treasure, and it took him half a month to open the formation.

However, Hei Feng did not compete with Yun Yi for the Hunyuan Pill Sutra. Although the Hunyuan Pill Sutra is unparalleled and extremely precious, it is useless to him. However, if this alchemy sutra comes to Yun Yi's hands, it will be different. It will definitely shine in the future.

"Hehe, but let Master Mao see what good thing this talisman is."

The black wind cat grabbed the talisman in the box with its claws, and the talisman immediately jumped up and fell into the black wind's hand.

A spiritual power turned into qi and fell on the spiritual talisman, including the spiritual talisman, but the silk of the spiritual talisman did not move, and there was no sign of being opened.

"I'm a little bitch."

The black wind was furious and threw the talisman on the ground.

"There is a ban on the talisman?"

Yun Yi asked curiously.

"If the ban is still so troublesome? There is a ban that Mao Ye cannot break in the world? Above this talisman, there is a king's aura and a powerful soul power blockade. The spiritual power reaches the level of the talisman, and there has been a qualitative change. With the talisman, with the talisman, unless it is a master of the Spirit King, no matter how bad it is, he must be a master of the Ninth Level of the First Line Heaven to open the talisman. With your current strength, you can't open the talisman."

Hei Feng said speechlessly: "I'm so mama. I don't know which old man left this box. He was so powerful that he couldn't open it in the end. What's the use."

hey-hey……

Yun Yi smiled, he didn't care about the angry Hei Feng. For him, he was already satisfied to get a treasure like Hunyuan Dan Jing this time.

Driven by curiosity, Yun Yi reached out and opened the Hunyuan Dan Sutra.

Hurry!

Yun Yi just turned the first page of the book and a golden piece of paper fell from the mezzanine on the first page.

Yun Yi had quick eyes and quick hands, and held the paper in his hand.

“Look at what is written on it.”

Hei Feng jumped over Yun Yi's shoulder, his eyes fell on the golden paper, and he was eager to find a way to open the talisman from it.

On the paper, rows of fonts are sonorous and powerful: I am the Medicine King Dan Chenzi. When I opened the Hunyuan Dan Sutra, I had already received the recognition of this king. But when I passed on my king's inheritance, I accidentally obtained the Hunyuan Dan Sutra. After spending my life, I could explore a trace of the mystery. I benefited a lot. Those who inherited me can study the Hunyuan Dan Sutra to fulfill my last wishes. All my wishes are in the spiritual talisman. My spiritual talisman needs to reach the level of the Spirit King before it can be opened. Opening it too early is harmful or useless...

"Medical King Dan Chenzi?"

Yun Yi frowned. The words on the paper were already very obvious. The treasure of this secret room was left behind. The medicine king Dan Chenzi, with a last wish on it. It can be judged that Dan Chenzi is no longer in the world, leaving the Hunyuan Dan Sutra for later generations.

The tone on the paper was sad, revealing the many unwillingness of Dan Chenzi during his lifetime. Before he could finish his wish, he set up the Five Days of Lihuo Formation to find his successor to help him achieve his last wish.

Dan Chenzi's last wish was sealed in a talisman that only an alchemist at the level of the Spirit King can open. It can be seen that this last wish is not so easy to accomplish. The most basic standard for completing this last wish is at least a master of the Spirit King.

Yun Yi is now only at the third level of the innate realm. He is very different from the Spirit King and still has a long way to go.

After the innate realm, there is the Spiritual Yuan realm. After the Spiritual Yuan, there is a first-line realm. Only when spiritual cultivation crosses the first-line realm can one become a king.

"Heifeng, you are knowledgeable and do you know Dan Chenzi?"

Yun Yi asked curiously.

"I don't know, just a little person."

Black Wind shook his head.

Damn it!

Yun Yi glared at Heifeng with anger. The alchemist at the Spirit King level was a small person in the eyes of this dead cat, so what is a big person?

Yun Yi ignored Heifeng and bent down to pick up the talisman that fell on the ground, carefully put it away.

"Senior Medicine King, since I, Yun Yi, have taken your inheritance, I will definitely help you achieve your last wish."

Yun Yi said solemnly to the empty box.

Yun Yi is a person who believes in cause and effect. Everything has a cause and effect. There is also a saying in the secular world that he uses money to eliminate disasters. No matter what the Hunyuan Dan Sutra has, or how ancient and modern it is, he only knows that this Dan Sutra is left by Dan Chenzi. If he gets it himself, he will get the inheritance of Dan Chenzi.

After taking the inheritance of Dan Chenzi, Yun Yi naturally had to help him fulfill his last wish. This was unswerving.

And that unopenable talisman will also become a goal for Yun Yi to continue to work towards the realm of the Spirit King.

One inheritance, one last wish.

One word, one promise.

This is Yun Yi’s promise to Dan Chenzi.
