After standing still, Lang Fei looked around and saw that he had arrived at the center of a hollow mountain, probably dozens of feet in diameter. The stone walls were sparkling, reflecting a dim red light like crystals.
At this point, Lang Fei turned his head again and looked at the source of the red light. In the center of the mountain was a blue halo two feet wide. The place where the light shone was not clear. Surrounded by ten red lotuses, those various red haloes
The light flashed out from it.
"This is the Sky Fire Cave." After the old Taoist said this, he used his fingertips to draw a ray of true energy on an inconspicuous stone wall above.
Suddenly, where the golden light shone, a circle of yellow-orange light appeared halfway up the crystal wall above his head.
In an instant, the entire mountainside was illuminated as brightly as day. Only then did Lang Fei see clearly that there were rows of neat jade crystals on the surrounding stone walls. Under the orange light, they shone with golden light, like countless golden jade crystals.
Normally. In addition to this, there is another strange phenomenon. There is some smoke floating in the jade wall, and the jade crystal seems to be as if it is nothing, and it is connected to the long mist in the void.
"This...is this the source of the fragrance of elixirs?" Lang Fei took a deep breath and realized that the fragrance of elixirs he smelled when he entered the cave was caused by the smoke before his eyes.
"Yes, this crystal is called 'Danxia Jade Crystal'. It is the best building material for building an alchemy room. It can not only isolate the filth floating between heaven and earth, but also retain the fragrance of alchemy. It can calm down the emotions and suppress the alchemy when the alchemist is refining alchemy."
Inner demons, and the wonderful use of providing some true energy."
After hearing what the old Taoist said, Lang Fei was shocked. He circled the crystal wall and found that there was no place like this in the entire mountain. Even the stone steps he stepped down before were made of Danxia Jade Crystal.
"If it's as the idiot said, there is a holy place in every branch of Danmen, as you can see in front of us, but the value of these jade crystals in front of you is probably not enough to buy several third-rate cultivation sects."
As if he had guessed what Lang Fei was thinking, the old Taoist smiled slightly and said: "The Patriarch Yanxia has the power to penetrate the heavens and the earth. This Tianhuo Cave is the inheritance treasure left by his old man to us descendants."
"No wonder..." Lang Fei nodded with understanding.
"Disciple, look!" After hearing this, Lang Fei hurriedly followed what the old man pointed out.
"Hey!" The place the old Taoist was pointing to was the center of the mountain's underground. It was previously difficult to distinguish under the dazzling blue light, but now the truth was revealed.
As seen before, the blue light is not there, but a fluorescent fountain. Rich water-like spiritual energy spurts out, reaching the top, turning into little green water droplets, covering a three-foot radius.
brightly lit.
"Master...Master, does this spring have a reputation?"
The old Taoist stroked his beard and smiled, with a look of joy on his face, and said: "This is not a spring, but a spiritual vein."
"Spiritual pulse?" Lang Fei was shocked. He closed his eyes and felt the luck carefully, and he felt that a mellow and sweet spiritual energy overflowed from the "fountain".
"What a pure spiritual energy!" Lang Fei exclaimed in admiration, and gently attracted a ray of spiritual energy. He saw it flying around the fingertips, like a pure and beautiful elf that was moving.
"This is the 'Qingxu Xuanmai'!" The old Taoist took two steps forward and sighed.
"Qingxu Xuanmai?" Lang Fei couldn't help but trembled, and the spirit on his fingertips instantly turned into wisps of fragrance and flew away as if he was frightened.
"The Heavenly Fire Cave contains the Qingxu Mysterious Vein, and the Ten Thousand Spirits Valley contains the Dragon and Tiger Mysterious Veins. Master, is it possible that these spiritual veins are also subdivided into many types?"
The old Taoist nodded and said: "Yes, like elixirs, spiritual veins are subdivided into four levels of heaven and earth, black and yellow. The dragon and tiger mysterious veins you encountered in the Ten Thousand Spirits Valley and the Qingxu mysterious veins in the Tianhuo Cave are both Xuanpin spirits.
pulse."
"Oh!" Lang Fei nodded thoughtfully, and then asked: "Master, since they both belong to Xuanpin spiritual veins, what's the difference between the two?"
The old Taoist led a wisp of spiritual energy, wrapped it around his fingertips, and replied softly: "The Dragon and Tiger Mysterious Veins are the energy that harmonizes yin and yang. And the Qingxu Mysterious Veins in front of me is even pure energy."
As he spoke, the old man walked forward slowly and said: "Fei'er, when I was refining the Zhuyan Dan, my master told you that the surrounding environment is very demanding. At that time, I used the dust-proof talisman to clean the elixir room.
Impurities. But in this Tianhuo Cave, there is no need to be so cumbersome. The Danxia Jade Crystal has already had a dust-removing and dirt-removing formation engraved by the ancestor. When refining the elixir later, you only need to draw out the spiritual energy from the Qingxu Xuan Vein and fill it with it.
The whole mountain will make alchemy twice the result with half the effort."
"It actually has the wonderful effect of improving the environment!" Lang Fei praised.
The old Taoist smiled when he heard this and said: "Not only that, spiritual veins are also of great use. Some elixirs not only require an extremely harsh environment when refining them, but also need to absorb endless spiritual energy when they are made into elixirs. And in this Qingxu Xuanmai
The spiritual energy is three points purer than the lower grade spiritual stone, so a good spiritual vein is an indispensable thing for the alchemy room."
Lang Fei nodded, walked to Lao Dao's side, pointed to the ten red lotuses surrounding the spiritual veins and said: "Master, what is this? How can the hot air in the mountain belly come out from it?"
The old Taoist didn't reply in time, but instead made a false move with his sword and injected a burst of true energy into the red lotus in front of him.
The fiery red essence flows gently on the lotus bud, and the petals slowly open. As the lotus blooms, waves of fiery air blow towards the face.
"Earth fire?" Sensing the strong earth energy contained in the heat wave, Lang Fei was slightly startled and said in confusion: "Master? What is the origin of this red lotus? How can it emit the unique heat of earth fire?"
The old Taoist chuckled and said: "Fei'er, my master is just urging the red lotus to bloom, and has not yet used the technique of igniting fire. Otherwise, what the core will emit will not only be hot."
"What?" Lang Fei was shocked, murmured a few words, then his face changed drastically, and he shouted with disbelief: "This... is this the immortal treasure 'Red Heart Fire Lotus'?"
The old Taoist laughed, nodded solemnly, and said: "Fei'er has good eyesight. This thing is exactly the 'Red Heart Fire Lotus', which was accidentally found by Patriarch Yanxia in a cave in the center of the earth after the Great Tribulation of Heaven and Earth. According to the historical records of Danmen,
When they were found, these 'Red Heart Fire Lotus' were already wilted. 'Red Heart Fire Lotus' was a creature of heaven in ancient times and was conceived in heavenly fire. It is thought that these ten immortal lotuses fell from heaven during the great catastrophe.
, and then fell into the depths of the Evergreen Formation, and survived by chance in the place where the earthly fire was steaming. But after all, it was only earthly fire, and its firepower was not as powerful as the heavenly fire. Not to mention the growth of these ten fairy lotuses, even their vitality could only be barely maintained.
Patriarch Yanxia accidentally obtained the fairy lotus, which was so precious that he did not hesitate to spend a lot of money to collect heavenly fire to cultivate the fairy lotus. Later, he transplanted them into the Heavenly Fire Cave. However, after the death of the Patriarch, the Danmen could no longer rely solely on its own magic power.
Those who can collect heavenly fire, but fortunately, the founder left a magic circle that can harvest heavenly fire during his lifetime. Therefore, the descendants of the ancestor Danhaizi used the great method to gather ten earth-core fire veins here. They are usually warmed by earth-fire, and every other
The formation must be opened once at a certain time, and the collected heavenly fire is used to warm and replenish the fire essence of the fairy lotus. In this way, these ten fire lotuses are still alive today after tens of thousands of years."
"That's it..." Lang Fei nodded, looking at the ten fairy lotuses at his feet and secretly feeling shocked.
"Fei'er, don't underestimate this thing. You think it's a burden to have the name of immortality." The old Taoist seemed to have guessed what Lang Fei was thinking, and designated the immortal lotus: "As far as the earth is concerned, although the immortal lotus is difficult to mature,
But it has a great use. Under these ten fairy lotuses are ten fire veins that go straight to the center of the earth. You should know that the violent firepower of the earth fire, mixed with the evil spirit of the earth, has a great impact on alchemy. No more than the Heavenly Fire Cave.
Generally speaking, these disadvantages are negligible under the influence of fairy lotus. The ten 'red heart fire lotus' located at the exit of the earth fire can purify the earth fire, block out the earth evil mixed in it, and only absorb the pure earth fire energy.
.Therefore, it is a big help when refining earthly gunpowder stones and some low-level elixirs."
At this point, Lang Fei just put away his contempt and circled around the ten fairy lotuses. Then he returned to the distance and asked again: "Master, since this Tianhuo Cave is a place for alchemy, why is there no alchemy furnace?"
?And the formation of gathering heavenly fire that you just mentioned."
The old Taoist gently stroked his long beard and said with a smile: "Fei'er, don't worry, look, isn't that the one in mid-air?"
Lang Fei was stunned for a moment, then looked up and saw that following the old Taoist's curse, a square-eared and round tripod with a simple shape and golden color appeared. After that, the changes did not stop, and three more figures appeared around the ancient tripod.
Small tripod.
"Fei'er, look again." The old Taoist kept pointing and shouting, and fired nine rays of fiery red essence into the void on the crystal wall.
"Ang..." A dragon roar came, with nine sounds, and nine huge dragon heads appeared on the surface of the crystal wall on the side of the ancient cauldron, as if a real dragon emerged from the water. Each dragon head was nearly ten feet long and wide, and the dragon's mouth was open.
To the belly of the ancient tripod.
"This cauldron, named 'Suihuo', was purchased by our ancestor from the Fangcun Holy Sect, who spent countless precious materials refining it."
Seeing that Lang Fei couldn't help nodding, the old Taoist pointed to the other three small tripods and said: "These three tripods are called 'Fire Fang'."
After saying this, the old Taoist moved his finger to the nine dragon heads and said loudly: "This is the 'Nine Dragons Swallowing the Sky Formation' that can attract heavenly fire!"
"Nine Dragons Swallowing Heaven Formation?" Lang Fei muttered softly, with a flash of shock in his eyes.
"Yes, this is the downward trend of the 'Nine Dragons Swallowing the Sky Formation', which is where the Heavenly Fire comes from. When refining the elixir, you only need to activate the 'Nine Dragons Swallowing the Heavens Formation', and the Nine Dragons' mouths will spit out the Heavenly Fire according to the formula."
"Good guy!" Looking at the nine menacing dragon heads from a distance, Lang Fei felt a chill in his heart for no reason.
After glancing at Lang Fei and shuddering, the old Taoist stretched out his hand and handed something over and said: "When I make the elixir later, your cold jade will not be able to block the heat of the heavenly fire, so I have to match it."
Lang Fei took it and saw that it was an exquisite green jade pendant, with Chang'e flying to the moon engraved on the front and a picture of the Moon Palace on the back.
"This is made of tens of thousands of years of cold crystal. Wearing it can dispel fire and stop dryness, and can withstand the residual heat of the sky fire." As he spoke, the old Taoist took another side and put it gently on his waist.
Seeing this, Lang Fei gently rubbed it for a moment and felt the coolness. But unlike the old man, he rolled his eyes, put it around his neck, and kept it close to his body.
