In the spacious quiet room, the hot high temperature spreads, making the secret room look like an oven, steaming hot. If ordinary people stay here for more than ten minutes, they may even be extremely difficult to breathe and run away in a hurry.

The entire body of the secret chamber is made of a red rock. This stone is called the crystal of the center of the earth. It is taken from the depths of the volcano. It is not only hard, but also emits extremely strong fire-attribute energy. It has extremely good results whether it is used to refine elixirs or practice.

There was no gap in the secret room, and it looked like it was like hollowing out an extremely huge crystal in the center of the earth.

In the secret room at this moment, extremely rare treasures of heaven and earth are scattered all over the ground. These treasures of heaven and earth are extremely precious, but they are placed everywhere like debris here.

The only difference is that there is an additional object to carry.

The extremely rich aroma of medicinal materials drifts out from it, and then steamed by the high temperature around it, the taste becomes much stronger.

In the center of the secret room, there was a crystal-like stone platform. On the stone platform, a thin figure sat cross-legged. In front of it, there was a green medicine cauldron floating. Inside the medicine cauldron, the dark flames were burning. The center of the flame could clearly see that the space had been broken, and even nothingness had become distorted. Such a terrible temperature spread out from the medicine cauldron.

But this temperature, which is hard to match even with the strange fire, is mostly isolated by this medicine cauldron. It is obvious that this medicine cauldron is not as ordinary as it appears.

Sitting cross-legged here, the person who showed his strong body naked on his upper body was Lin Qingyun. He had not refined elixirs for a long time, and his skills would somewhat retreat. This has nothing to do with the strength of the soul power. After all, the art of refining medicine can easily become unfamiliar with time.

What's more, he made a bold statement and arranged a healing pill for Murong Bo within seven days, while his alchemist level was only at the peak of the sixth grade.

Inside the medicine cauldron, the dark flames rose, and two elixirs could be seen faintly, and the rich elixir fragrance spread out from it.

The prototype of the elixir gradually became round under the scorching flames. After about half an hour of touching, Lin Qingyun's closed eyes suddenly opened, and he bounced his fingers, and the medicine flew away.

Two green rainbow lights rushed out of the medicine cauldron and then automatically threw them into Lin Qingyun's hands.

The two round pills that fell into Lin Qingyun's hands were only the size of a thumb. Although the pill was small in size, if it was placed outside for auction, it would definitely arouse the envy of many people.

The elixir is called Xuanming Shou Pill. It is a elixir that increases life span. Its grade level is barely at the low level of the seventh grade. Its function is to extend the life span of the user for fifty years. For the strong man who has exhausted his life, this is undoubtedly a battle with the heavens. Even if he loses everything, he will try his best to shoot it.

Even with such a pill, Lin Qingyun just took a look, shook his head, put it in a jade box, and threw it on the ground aside.

If you look in that direction, you can see that there are more than a dozen jade boxes placed on the ground. Even if the silk is tight, there is still a very rich elixir fragrance seeping out, without exception, all of which are elixirs above the peak of the sixth grade.

Lin Qingyun has been here for a whole day, and has been repeatedly refining pills above the sixth grade peak. He is reviewing his skills and feel. After all, he hasn't refined it for a long time.

However, after one day of practice, the previous techniques have basically returned and are barely at their peak. The next step is to refine a real seventh-grade low-level pill.

How to identify a seventh grade pill?

The only criterion is whether this pill has experienced thunder tribulation.

"Let's start!"

After a light breath of hot and turbid air, a book was presented in the palm of Lin Qingyun's palm, which was the Taiyi Xuandan Record.

Somehow?

Or maybe it was missing Lao Xuan, and Taiyi Xuan Dan Record seemed a bit ordinary.

I really miss it!

Lin Qingyun thought to himself, and the image of the old man in his mind appeared in his mind. Although there were not many words, the former was his guide on the path of elixir, and he was still very grateful.

Old Xuan's departure was not beyond his expectations. He was a person from another world after all.

"Harmful!"

Shaking his head, Lin Qingyun smiled faintly, turned the book in his hand, the pill recipe recorded on page 9, Fengyu Tiandan.

Just once, he remembered that the golden world suddenly appeared in his mind, and he practiced tens of thousands of times in that moment.

At this moment, his mastery of this pill recipe had reached the point of perfection.

The most important material of Fengyu Tiandan is the real blood of the phoenix, but how could there be a real phoenix in this world? So it can only be replaced by the essence and blood of the Tianyao Ancient Phoenix.

A faint blue ring suddenly appeared in Lin Qingyun's hand, and the light flashed, and a huge body appeared out of thin air in the quiet room.

An extremely rich and stench hit in an instant. This huge monster that couldn't see clearly was the Heavenly Demon Ancient Phoenix, a seventh-level monster.

The flames swept through, instantly burning the completely weathered flesh and blood of the Heavenly Demon Gu Feng into nothingness. An indelible black rotten smell rushed out, which corroded the extremely hard crystal of the earth's center into a hole the size of a bowl.

"Tsk tsk, you're still uneasy even if you die!"

Staring at the huge white skeleton that gradually showed its appearance, the skeleton could not be said to be white, a little blue, with a faint blood-red color mixed in the blue, which was quite strange.

In the skeleton like a jade, you can see extremely rich light flashing, which is the blood marrow contained in the skeleton, which is the essence and blood.

Even after death, the body of this heavenly demon ancient phoenix still exudes extremely powerful pressure.

"It's going to cause trouble if you die."

Lin Qingyun smiled faintly, flicked his fingers lightly, and the flames swept over again. At first, it emitted an extremely powerful aura of pressure, and it was instantly annihilated.

The bones, like jade, quickly turned gray and white, and the blue-red energy rose and accumulated over the quiet room.

In a moment, the bones turned into ashes, and a whirlpool quietly appeared in the accumulated blue-red energy clouds.

The vortex was full of light condensed. Half a quarter of an hour passed before a drop of green and red blood that had condensed to its extreme fell down, suspended in mid-air, attracting resonance between heaven and earth, wind-attribute energy riots, and wind roars.

After an hour passed, only ten drops condensed, and in the clouds that had not yet dissipated, a more dazzling blue and red light was gathering.

"Change!"

Lin Qingyun shouted lightly, clenched from the air, like holding the sky and the earth in his hand, the space twisted in his palm, the energy clouds quickly contracted, and the ultimate light bloomed, and a bright and dazzling green and red magic core appeared in the air.

With a casual wave, the essence and blood and the magic core disappeared. At this moment, Lin Qingyun suddenly frowned slightly and turned his head to look at the closed stone door.

"Bang!"

The stone gate moved, and a person walked slowly. It was Princess Cangyue.

"Why are you here? Didn't you say you can't disturb me?"

Lin Qingyun frowned and said, before he was in seclusion, he had already instructed no one here to get close. Obviously, the young lady had surpassed this rule.

"This is my place, why can't you enter?" Princess Cangyue leaned against the edge of the door frame and said lightly.

Lin Qingyun could not deny this, and he did borrow Princess Cangyue’s cultivation room.

But he could also see that what was the so-called Princess Cangyue coming?

"Do you want to stare at me and see if I really have the ability? Or just show off!"

As if she was penetrated by her purpose, Princess Cangyue's face looked a little less natural. She coughed lightly to hide the embarrassment, and forced herself to calm down and said, "I...I'm just here to see if you've made trouble in my practice room."

Having said that, her eyes kept scanning the space, looking at the medicinal materials scattered on the ground and the jade box emitting a rich elixir fragrance, she frowned.

She could feel that the elixir fragrance emitted from the jade box was not very strong. The elixirs were at most seventh grade low-level, which was too far apart.

This is not the strength that an eighth-grade alchemy master should have!

A sudden burst of anger came.

"You deceived us!"

Princess Cangyue took a step, and the spear in her hand had already hit Lin Qingyun's eyebrows. It was only an inch away from her, and she could penetrate her eyebrows.

But it was this inch that Lin Qingyun pressed her finger against her. He smiled faintly, "You are a little anxious."

"You said you are the master of alchemy and you can cure your grandfather's illness, but why did the pill you refined are only seventh grade? You said you were not cheating."

Princess Cangyue glared at her, but she put away the spear in her hand helplessly. The strength was too different, which made her helpless.

"I didn't lie to you." Lin Qingyun's eyes turned slightly and said with a faint smile: "I said I had made it in seven days, and now there are six days left. Why don't we make an agreement? Six days later, I will cure your grandfather's illness, and you apologize to me for the mistakes you have made."

"What does this mean?"

"How can I believe you?"

Princess Cangyue still disbelief and said coldly: "Your strength is stronger than me, and even my father is inferior to you. You have the strength of Dou Zun, the soul of the spiritual realm, and such a powerful skill, the entire northwest region can come and go freely except for that forbidden area."

"If you can't make it, lose the agreement and get out of here, how can you fulfill the agreement?"

"You are cautious."

Lin Qingyun was laughing and crying. Although he was a little rogue, he had not yet achieved this and did something breach of trust.

"What do you want me?"

Lin Qingyun asked.

"I... need the most precious thing in you." Princess Cangyue said after hesitation.

She didn't know what to do. Rather than being angry, she still had a glimmer of expectations. After a moment of confusion, she chose to believe it again.

"sure!"

Without hesitation, Lin Qingyun took off the lanyard around his neck, wearing a red ring, and then took off the emerald green ring on his fingers, and also wore it together.

But he did not hand it out immediately, but said, "These two rings were given to me by my fiancée, and they are tokens, and their meaning is extraordinary. I can give them to you for custody, but how do I believe that after completing the agreement, you will return them to me."

"It's better to do this, and you can also take out one of your most precious things in exchange."

"What's wrong with this?"

As soon as he finished speaking, Princess Cangyue took off the red rope hanging around her neck, and a jade pendant hung on it. It was very ordinary, but it was better than exquisiteness.

As soon as he picked it up, Princess Cangyue hesitated obviously. After a while, she handed it out reluctantly.

Then he shouted softly, "Be careful, if it breaks, I will only ask."

Lin Qingyun smiled faintly, took it gently, and handed over the red rope in his hand.

The warm jade feeling in his hand came from the woman's body temperature that had not yet dissipated. A faint fragrance hit him, which actually made Lin Qingyun feel heartbeat.
