The sloppy old man spoke lightly to Ling Feng. He knew that it had just begun and it would take at least twenty days before the core was completed. He could not let Ling Feng stand here and wait.

"Xiaohong, take this little brother into the house to rest!"

At this moment, the Demon Flame Valley Master, who had his eyes closed, spoke lightly.

"hiss!"

The little red snake, after responding, jumped up from the magma, curled up into a ball, and then glowed red.

Finally, the red light shrank sharply and turned into a graceful figure. The giant red snake actually turned into a girl.

This girl looks to be only twelve or thirteen years old. She is wearing a red gauze dress. She has a delicate face, fair skin, curved eyebrows, and blood-red eyes. The most eye-catching thing is her supple hair.

Long red hair.

Upon closer inspection, Ling Feng discovered that her hair was actually filled with little red snakes.

"Transformation?"

Ling Feng was stunned. He didn't expect that this big red snake was so powerful. Regardless of whether it's a monster or a spiritual beast, if you want to transform, you must have the cultivation level of the Nascent Soul realm.

But this is not absolute. Some special monsters and spiritual beasts can still transform into human form even if their cultivation level has not reached the Nascent Soul realm.

The big red snake in front of her gave Ling Feng a strong feeling. She should have transformed it with her own strength.

"What are you looking at? Come with me!"

The girl in red noticed that Ling Feng looked at her in a daze, her red little mouth curled up, and then she walked towards the yard. When she passed by Ling Feng, Ling Feng could smell a faint fragrance.

Ling Feng came to his senses and was about to follow the girl in red and walk in, but the sloppy old man waved his hand and threw a storage bag to Ling Feng.

"In this storage bag, there are pill condensation techniques and bridge building techniques! During this time, you should practice it!"

The sloppy old man said lightly to Ling Feng.

He had previously said that he would teach Ling Feng a very powerful pill condensation technique, and Qi also had a technique that could communicate between the golden pill and the foundation building platform. This technique he called the bridge technique.

Holding the storage bag, Ling Feng walked towards the yard.

After entering the courtyard, Ling Feng felt a chill hit his face. The fire-attribute spiritual power in the courtyard was much thinner than outside.

"Go to the room on the left. The room in the middle is mine, and the room on the right is my master's. Don't run around!"

The girl in red pointed to a room on the left and said, then she reached out and took out a red crystal stone and played with it in her hand.

Ling Feng's eyes were immediately attracted to the red crystal in the girl's hand. He could feel that the fire-attributed spiritual power around him was constantly converging towards the red crystal in the girl's hand.

"What is this in your hand?"

Ling Feng couldn't help but ask.

"This? It's called Fire Cloud Crystal. I picked it up from under the magma. There are many more down there!"

The corner of the girl's mouth curled up slightly, and her white onion-like fingers held the red crystal stone and kept turning it.

"Can you give me a piece of this?"

Lingfeng looked up at the girl in red. He could feel that this fire cloud crystal should be able to be refined by the incense burner like the fire attribute ore he dug underground in the Qingniuling Mulberry Garden, thus accelerating his growth.

Training speed.

"You want it?"

The girl in red tilted her head, staring at Ling Feng with her flashing red eyes, and a playful smile emerged from the corner of her mouth.

"Yes, I can exchange things with you!"

Ling Feng nodded. He also knew that he was not very familiar with the girl in red, so there was no reason for anyone else to give him the crystal.

"Oh, what can you exchange for me? You are just a rookie in the foundation-building realm. Although my fire cloud crystal is not very precious, it is not something you can exchange for casually!"

The girl in red spoke with a somewhat disdainful tone. She didn't think Ling Feng could offer anything valuable in exchange for her.

"This, let me think about it!"

Lingfeng thought for a while, and then took out a purple lin pine cone. In his opinion, the only thing he could exchange with this girl was this purple lin pine cone.

Although he still had Dragon Vein Fruit and Dragon Eye Fruit, he didn't want to exchange them.

"What is this?"

When the girl in red saw the purple pine cone, her eyes lit up slightly and she was immediately attracted.

At this moment, the Zilin pine cones also began to emit a strong fragrance. The girl in red sniffed it for a few times and suddenly felt that her saliva was about to flow out.

"This is the Zilin pine cone, which is rare but not sought after. I got it by chance. The pine nuts of this pine cone have a unique taste and crispy texture. Not everyone can eat it!"

Ling Feng smiled faintly, the purple lin pine cone in his hand was indeed a rare commodity, and he was not bragging.

"Okay, then I'll switch with you!"

The girl in red nodded, snatched the purple lin pine cone from Ling Feng's hand, and then stuffed the red crystal into Ling Feng's hand.

"this……"

Ling Feng was stunned for a moment. He originally wanted to bargain with the girl in red, but he didn't expect that the girl in red would move so quickly.

"Okay, I'm going to eat pine nuts. You can go back to your room and rest. Don't run around!"

The girl in red said something to Ling Feng, then turned around and walked back to her room.

Ling Feng smiled bitterly, then lowered his head and looked at the Fire Cloud Crystal in his hand.

This fire cloud crystal is diamond-shaped, about the same size as an ordinary egg, and is blood red. There are some faint lines flickering on the surface, and there seems to be red liquid flowing inside.

After staring at the Fire Cloud Crystal for a while, Ling Feng found that the crystal seemed to be able to absorb people's attention, and he quickly looked away.

He walked to the room on the far left, opened the door and walked in.

The furnishings in the room are very simple, with only some ordinary tables, chairs, bed cabinets, and even the floors are exposed slate instead of soft carpets.

After closing the door, Ling Feng felt that it suddenly became quiet. The sound insulation effect of this room seemed to be very good.

He walked to the bed, summoned the incense burner, opened the lid, and threw the Fire Cloud Crystal in.

With a thought, the incense burner turned into a blue light, penetrated into the palm of his hand, and returned to his Dantian.

Ling Feng sat cross-legged on the bed and began to run the nameless Qi Refining Technique. The incense burner in his Dantian began to rotate, and traces of red mist floated out of the incense burner. Ling Feng instantly felt a burning sensation.

At the same time, Ling Feng also ran the Phoenix Tribulation and began to refine the red mist.

"Chi Chi!"

The red mist was refined into the power of the Phoenix, and Ling Feng's body trembled violently because he felt that the red mist refined from the fire cloud crystal contained more fire attribute power than ordinary flames.

The fire attribute power it contains is even more domineering.

"What a terrifying power! If my physique and meridians hadn't strengthened a lot during this period, I probably wouldn't have been able to withstand such overbearing power!"

Ling Feng sighed secretly in his heart, and then started practicing with concentration.

Outside the courtyard, the master of the Demon Flame Valley is still concentrating on refining the elixir. This is the first time he has refined the destiny elixir core, and it may be the last time, because the material for the destiny elixir core is too rare.
