"Whew!"

Just as Lu Yan was overjoyed to see the legendary alchemy room for the first time, suddenly a wave of heat suddenly hit his face, making Lu Yan immediately wake up from his excitement.

"How can there be hot air?"

Lu Yan was secretly shocked in his heart.

At this moment, the Fire Flame True Qi in his body suddenly started to work automatically, which made Lu Yan feel even more shocked.

"Is there a vein of fire here?"

Lu Yan muttered in a low voice.

With a twist of thought, he immediately released a trace of spiritual power to cover the entire secret room.

"Sure enough, there are such fire veins! And it's right under the stove!"

Soon Lu Yan found the location of the fire vein, and immediately exclaimed.

"It's really a hillbilly! Since alchemy can be made here, then there must be a fire vein, otherwise how can you do alchemy, unless...!"

The taunt of the sword spirit suddenly sounded in Lu Yan's mind.

"Unless what?"

Lu Yan didn't care about the sword spirit's ridicule, but became interested in the last half of the sentence behind it.

"You don't know alchemy, you don't need to know this!"

The sword spirit said coldly, and then fell silent again.

"Huh!"

Regarding Sword Spirit's words, Lu Yan suddenly felt a little speechless.

"Heh, since you don't understand alchemy, then I'm going to try it!"

Soon, Lu Yan's eyes were attracted by the row of bookshelves at the back, and he immediately showed a smile and said confidently.

But to Lu Yan's disappointment, the sword spirit did not respond to his words.

Lu Yan shrugged his shoulders, and then bypassed the Nadan furnace and came to the innermost row of wooden shelves.

There is only a row of wooden shelves, and there are two floors, each of which has about dozens of thread-bound books.

The surface of these texts is covered in a thick layer of dust.

Lu Yan waved his sleeves, and a wave of energy flew out, sweeping away the dust in an instant.

"It's all made of animal skins! No wonder they can still be preserved after all these years!"

Lu Yan gently picked up a classic book and flipped through it, and then secretly exclaimed.

"Huh!"

"Why are they all classics about herb varieties and attributes, and where are those alchemy books?"

What made Lu Yan feel embarrassed after going through all the classics was that he didn't see the classics with alchemy, which made him slightly disappointed!

"How can this be like this? Shouldn't it, there are so many classics related to alchemy, why don't there be Dan books?"

Lu Yan still couldn't believe it.

"Huh, what's that?"

Just when Lu Yan secretly sighed that there was no Dan book, something black on the ground behind the wooden frame caught his attention.

Lu Yan walked around the wooden frame, then walked to the black thing and squatted down.

Looking at the half-exposed black object, Lu Yan's heart suddenly became a little excited inexplicably, and he cautiously reached out and touched the black object.

"Poof!"

Lu Yan suddenly felt a little itchy in his nose, and then couldn't help but sneeze, and instantly a puff of dust was blown up by the wind.

"Well, it's a book! Is it a Nadan book?"

The dust was blown up by the wind and finally revealed the full surface of the black object, which was a book.

Lu Yan guessed a little excitedly.

Gently picking up the black notebook, Lu Yan gently stroked the cover and wiped off all the dust.

"It's so soft!"

"Huh"

The sword spirit, which had been silent, suddenly appeared

There was a faint thud.

At this time, Lu Yan sighed at the softness of the cover, and did not notice the voice of the sword spirit.

Although this cover was very soft to the touch, Lu Yan felt that it was very tough.

Turning over the cover, the first thing that catches your eye is the six big characters of "Nine Heavens and Stars Danjue".

Lu Yan was immediately overjoyed, and a happy smile gradually appeared on his face.

Lu Yan couldn't wait to continue to turn a few more pages, and the joy on his face became stronger and stronger.

"Sure enough, it's Danshu!"

Lu Yan cheered excitedly.

At this time, Lu Tianqi and Lu Wushuang's excited voices were also heard next door, obviously they had each found something good.

"It seems that I have to study it carefully when I go back, so that I can refine the pill by myself in the future!"

Soon Lu Yan put away his excitement and regained his composure.

He carefully put the "Nine Heavens and Stars Pill Formula" and all the other classics on the wooden shelf into the space ring.

In the end, Lu Yan also put away the Dan furnace, because just now the sword spirit said that the grade of this Dan furnace is not low, and if he wants to learn alchemy in the future, how can he do it without the Dan furnace!

"It's all effortless!"

Lu Yan couldn't help but sigh his good luck in his heart!

However, what made Lu Yan feel a little disappointed was that all the pills in the porcelain bottles on the other wooden shelves had become invalid and had become waste pills.

"Hehe, I'm still a little greedy!"

Lu Yan couldn't help but laugh at himself.

"Next is this vein!"

After the Dan furnace was taken away, the place where the Dan furnace was originally located, a hole the size of a human head was exposed, and a faint trace of fiery red reflected out, and bursts of scorching breath wafted out.

Lu Yan immediately sat down directly, then put on a practice posture, and then closed his eyes and entered the state of cultivation.

When he got the "Nine Heavens Star Pill Formula" just now, Lu Yan originally planned to study it carefully, but at this time, the energy in his body that the Holy Emperor Sword had absorbed the essence blood and energy of the Fangshi Essence Blood and Energy Feed suddenly appeared a trace of riot.

In this case, Lu Yan had no choice but to put aside the matter of studying the Danshu first.

Since the last time he absorbed that fire spirit in the Dragon Flame Cave, Lu Yan's Heavenly Flame Technique had already reached the realm of the second layer of rootless fire.

At this time, as soon as the Tianyan Jue was running, the pure energy stored near the dantian immediately surged towards the limbs and bones of the whole body with a bang.

Those pure energies and Lu Yan's own fiery true qi were constantly blended and assimilated in the meridians, and the energy after assimilation was also imbued with scorching attributes, and constantly refining every inch of skin and every cell on Lu Yan's body!

Under the tempering of the scorching fiery true qi, those black suppressions were continuously expelled from the body.

And this assimilated energy returned to the dantian along the meridians again

"Boom!"

As the red crystal nucleus of the dantian continued to absorb these energies, the aura on Lu Yan's body became more and more vigorous, and the white gas continued to bubble from the top of his head.

"Whew!"

"It's still not good, it's still a half-step refining god realm!"

Lu Yan suddenly opened his eyes and exhaled a breath of turbidity, a little disappointed.

The pure energy that Lu Yan absorbed just now was enough to be worth all the energy of the five innate peak powerhouses, but he still hadn't broken through the half-step realm of refining gods.

The most important thing is that he has a much more understanding of spiritual power than before, and after absorbing these pure energies this time, his spiritual power and his own energy have been greatly improved, but he still hasn't broken through that level.

However, Lu Yan quickly regained his confidence, and he glanced slightly at the entrance of the cave next to him that was bubbling with a trace of hot breath, and a smile gradually appeared in his eyes.

Lu Yan closed his eyes again, and then looked

Seeing that the entrance of the cave suddenly became more and more bright, a scorching vitality gushed up, and then converged on the top of Lu Yan's head to form an arc-shaped vortex, and finally slowly drilled into Lu Yan's zenith acupoint.

As time went on, the aura on Lu Yan's body became stronger and heavier, and a trace of black gas flew out of his mouth and nose.

......

In the secret room on the left, Lu Wushuang, Lu Tianqi and Wu Sanniang were gathered together at this time.

"Who left this treasure, there is a room full of martial arts!"

Standing at the door, Lu Tianqi looked at the dozen rows of wooden shelves in the secret room and exclaimed.

On top of those wooden shelves, there are densely packed with all kinds of classic books. On the side planks of the wooden frame, the categories of exercises are written.

"Wood Attribute Exercises!"

"Fire Attribute Exercises!"

"Earth Attribute Exercises!"

"Water Attribute Exercises!"

"Metallic Exercises!"

...

"Oh my God, this is a priceless treasure!"

Lu Tianqi couldn't help but be excited again.

"Let's go, let's go over and see if there are any exercises that suit you, but everyone should pay attention, no one has been to this place for so many years, and these classics may have been a little corrupted, so you must be careful!"

At this time, Lu Wushuang was also excited, but he still kept his composure and said.

"Hmm!"

"Hmm!"

Lu Tianqi and Wu Sanniang nodded at the same time.

Immediately, the three of them couldn't wait to run over, each chose a wooden frame, and then carefully picked up the classics and looked through them carefully.

""Gengjin Five Uniques" Xuan-level High-level"

""Nine Heavens Sunset" Xuan-level Intermediate Level"

"Wind Leg Method" Xuan-level Intermediate Level"

""Nine Suns Agni" Ground Level Elementary"

"Ten Miles of Spring Breeze" Wood Exercises, Xuan-level High-level"

""Extending the Bone Palm" Xuan-level Beginner"

""Shocking Sword Technique" Xuan-level Intermediate Level"

"Avalanche Fist Xuan-level Intermediate Level"

"Tiger Roaring Dragon Roar" Xuan Rank Beginner"

......

"Wow, this row is full of exercises above the Xuan level! And these classics are actually made of animal skins and are well preserved!

Lu Tianqi couldn't help but exclaim after putting down the last classic!

"It's the same on my side, but all the classics on the entire wooden frame add up to only thirty copies!"

Lu Wu held a book in both hands and replied with a smile.

"It's the same on my side, but I haven't found a suitable exercise for the time being!"

Wu Sanniang on the other side also replied, but there was a faint disappointment in her voice.

"I haven't found a suitable one yet, you go to the other wooden frames to see if there is a suitable one, when the time comes, we will each choose a suitable one, and let Lu Yan put away the rest, with his current strength, it is estimated that he will not be able to look down on these exercises, but it should be good to leave them to the family!"

Lu Wushuang comforted Wu Sanniang with a smile, and then said lightly.

Immediately, the three of them put the books back and walked towards the remaining wooden shelves, and even in the end, the whole secret room was surprisingly quiet, except for the sound of brushing and flipping books. All three of them were engrossed in finding the exercises that suited them.
