The three of them walked down the stairs of the underground passage.

This secret vault is located in the underground of the outer hall of the Smoke Dragon, the area is not large, and there are not many things stored in it. However, it was clear that no one had ever visited this vault, and this discovery lifted the spirits of all three of them.

Qin Feng's index finger and middle finger were pinched, and a cluster of crimson flames danced on his fingertips. In the smoky room, you can see some light.

Through the dim light of the fire, I could vaguely see a row of iron frames in the basement, which had almost corroded over time. On the iron frame, there are also the remains of some items.

Hundreds of years have passed, and most of the things stored in this basement have been damaged.

The three of them counted the things that were finally preserved, and there were three more.

The first one was a jade bottle containing the pill, with a label with the name of the pill on it, and the handwriting was long unreadable.

This bottle of elixir, of course, was handed over to Qin Feng to identify, he was the only soul among the three. The pills that come from unknown sources cannot be eaten casually, some of them are waste pills that the soul person accidentally refined, and it is harmful and useless to eat them, and there are some pills that are specially refined by the soul person, and it will be even worse if you eat them.

Qin Feng uncorked the bottle, sniffed it lightly, and then closed the cap: "Luckily, it's a fourth-order Tongqi Pill, but there is only one." ”

Tongqi Pill is suitable for martial artists in the spiritual realm and the wheel realm, which can strengthen the muscles and bones and expand the acupoints, which is quite precious. However, Qin Feng still didn't look down on this pill, as long as he had the materials, he would be able to refine the Tongqi Pill by himself now. In terms of medicinal efficacy, the newly refined Tongqi Pill is of course more effective than the Tongqiao Pill that has been stored for hundreds of years.

After Qin Feng explained the function of the Tongqi Pill and said that he didn't need it, Su Huan and Lei Yun glanced at each other.

"I've already taken the Tongqi Pill once, and it's a waste to eat it again," Su Huan stroked the hair next to her ears, "So, I don't want this pill either." Thunderclouds, it's yours. ”

"Hehe, then I'm welcome. Lei Yun smiled and took the pill.

The second item was a piece of bone, covered with dust and indecipherable. It's just that the texture of this bone is very good, and it feels relatively warm to the touch, so it is definitely not ordinary.

"Qin Feng, can you tell the origin of this bone?" asked Su Huan.

Qin Feng observed for a while, slowly closed his eyes, and separated a trace of soul power, extending into this bone.

Airplanes!

Qin Feng suddenly had an illusion in front of his eyes, a flame dragon, with his head raised and roaring, and his power was amazing.

"Hmm...... I know, this is a piece of Fire Demon Jiao's Jiao bone!" Qin Feng was a little surprised, but also a little happy, he could feel that this Jiao bone was heavy, which meant that its bone marrow essence had not been completely lost, which was just right for Qin Feng.

You must know that Qin Feng's cultivation of the Nine Yang Battle Body is to use the bloodline and bone essence of the fire attribute fierce beast to assist in cultivation. With this Fire Demon Jiao Bone, Qin Feng was confident that he would push his Jiuyang Battle Body to a higher realm.

"Congratulations. Su Huan smiled slightly, she could tell from Qin Feng's expression that he needed this Fire Demon Jiao Bone.

"I'm not pretentious, this piece of bone is really useful to me. Qin Feng said.

Su Huan nodded: "I am a water attribute blood qi, and I don't need this kind of thing myself, so it should belong to you." ”

The last item, a yellowed animal skin with criss-crossing passages, appears to be a map of the underworld.

The three of them looked at it carefully for a while, but they couldn't judge the area represented by this animal skin map. In the end, the map was handed over to Su Huan to put away.

"I'll eat the Tongqi Pill first and cultivate for a while...... Grandma's, after a fight with the people of Bailiu Academy, I realized that my strength was not enough. Thundercloud said, rubbing his hands.

"I'm also going to use the essence of the Fire Demon Jiao Bone to cultivate......" Qin Feng glanced at Su Huan and said a little apologetically, "Thunder Cloud and I have both obtained useful treasures, but it has made you suffer." ”

"What does it matter, it's just chance, you can't force it," Su Huan was very indifferent, "The map I got may not be useless." You cultivate with peace of mind, and I will protect the Dharma for you. ”

Su Huan's soft temperament is indeed like a spring breeze. At that moment, Qin Feng and Lei Yun sat in the two corners of the basement on the left and right, and began to cultivate.

Lei Yun's cultivation is very simple, directly swallow the Tongqi Pill and regulate blood qi. A thunderous sound of blood and qi erupted in his body, sometimes like a sea tide, sometimes like a storm, and the power was extraordinary.

"Thundercloud's foundation is quite solid, and it is better than Cao Hualong, the son of the Marquis of the Green Python. It is no fluke that he can sit in the fourth position on the list of strong people. ”

Qin Feng only glanced at it, then withdrew his gaze and took out the smoky Night Demon Furnace from the storage ring. Under the infusion of blood and qi, a crackling sound sounded.

Su Huan was protecting Qin Feng next to her, and when she saw Qin Feng using her soul refining methods, she couldn't help but show an interested look.

"Mind if I ask?" Su Huan asked first, she knew that some soul people were very taboo when refining items.

"Hehe, I just used the soul refining technique to force out the essence of this section of Jiao Bone, which is very simple and will not be disturbed. Qin Feng smiled. Even if it was refining a beast soul weapon, Qin Feng was also a freak who could speak while melting his soul, and it was nothing to him to be single-minded.

At the bottom of the Daredevil Furnace, a puff of crimson flames erupted, and the first step was successful.

That section of the Fire Demon Jiao Bone was infused with blood qi by Qin Feng's right hand and absorbed into the Night Demon Furnace. The temperature of the blood qi flame suddenly erupted, completely engulfing the fire demon bones.

Crackling, the bones of the fire demon burned in the red flames. The outer layer of dry bone gradually begins to burst and fall off.

After hundreds of years of storage, the outer bone of this Fire Demon Jiao bone no longer has any essence energy, and as soon as it is roasted by the flames, it becomes powder and is sprinkled one after another.

As the outer skeleton fell off, a trace of liquid gradually appeared on the inner wall of the bones of the Fire Demon Jiao Bone, exuding a light red luster, and a trace of gloomy energy breath slowly spread.

"Could these pale red liquids be the essence of the Fire Demon Jiao's bones?" asked Su Huan in a low voice.

"Not bad. Qin Feng carefully controlled the intensity of the flames, in case it was burned by the open flames to the essence of the Demon Jiao, if it was steamed dry, it would be a waste of time.

Qin Feng raised the Fire Demon Jiao Bone a few inches higher, and slowly roasted it with the outermost layer of the Void Fire of the Blood Qi Flame. The tongue of fire licked the fire demon bone from time to time, and the pale red liquid became more and more, drop by drop, attached to the inner wall of the fire demon bone, like agate.
