Xiao Yan looked at the silver light emitted by the gossip pattern on the roof of the Dan house, and a large number of atlas words appeared in the light.

Although he had never seen the real Tongtian Dan Formula, nor had he taken the Tongtian Pill, Xiao Yan could still see at a glance that these atlas words were the Tongtian Dan's Dan, and the first line of the list of medicinal materials was the ninth-order Tongtian Grass.

Xiao Yan's eyes were full of brilliance: "Master, our Danfang, can we still reverse the Dan prescription from the existing Dan medicine?"

"Yes, exactly. Lin Feng looked calm on the surface, as if he had already known about it, but in fact, he was as surprised as Xiao Yan in his heart.

The refining of elixir is not only about refining the medicinal power and aura in the medicinal materials, but also about many complex changes and fusions.

A Dan prescription is not a simple list of medicinal materials, but a comprehensive composition of many techniques.

Even the power of the Yuan Shen couldn't reverse launch a complete pill based on an existing pill.

It may still be possible for a relatively low-level pill, but if the level is a little higher, then you don't have to think about it at all.

The Bagua Array on the roof of the Huitian Golden Pavilion could actually be reversed from the pill to the Dan Fang, which was definitely a thing that made Lin Feng happy, not only that he could greatly expand the reserves of the Dan Fang in his own Dan room.

More importantly, it is possible that the Xuanmen Heavenly Sect may recreate many of the ancient Dan recipes that have been lost.

After tens of millions of years of development, countless sects have risen and countless monks have been born, but there are also many sects that have been annihilated, and many capable people have fallen, and they have been annihilated in the long river of history.

And with their disappearance, many rare Dao methods, supernatural powers, and elixir prescriptions were also lost.

Some of these lost panaceas. There are also pills that have been refined and finished to be passed down to the world, but the pills have been completely lost.

There is no Dan Fang. It is also impossible to produce new elixirs, the original remaining elixirs. There will always be a day when they will be exhausted, and these pills will eventually inevitably disappear in this world.

"If such an elixir falls into my hands, with the help of the Heavenly Golden Pavilion, I can make those lost prescriptions reappear in the world. Lin Feng thought in his heart: "Well, thinking about it this way, the value may not be in the pill itself, if it is operated properly, there may be some other gains." ”

Of course. Having a pill does not mean that you will definitely be able to refine the elixir, and some of the materials required for the elixir are more special and precious.

For example, if there is no ninth-order Tongtian Grass, even if there is a Dan Formula, it will not be able to refine it.

But even so, this discovery was also precious to Lin Feng, and the thoughts in his mind were spinning, and he had many thoughts in an instant: "Try to collect all kinds of high-grade rare elixirs, even if there is only one." ”

In addition to collecting other elixirs. Lin Feng also instructed Xiao Yan not to forget his own technical innovation.

Out of the Dan room, Lin Feng came to the scripture building next door.

Compared with the thick and brilliant Huitian Golden Pavilion, the Tibetan Scripture Building is much simpler, and there is a bit of antique charm in it.

The attic is nearly three feet high. Divided into three layers, the whole body is made of green bamboo that shimmers with purple light.

Lin Feng entered the attic, first in the empty outer room. Continue inward and through a passage. It is where the first floor of the library is located.

In the library covering an area of thousands of square meters, rows of bookshelves are neatly stacked. It's just that the shelves are empty at the moment.

Lin Feng frowned: "Does this mean that I want to fill it myself?"

He rubbed his fingers against the bookshelf, feeling that there seemed to be a faint aura flowing in it, and the trajectory was subtle and profound, and he couldn't help but move in his heart.

After pondering for a while, a purple light suddenly lit up in the pupils of Lin Feng's eyes.

In the purple light, the mysteries of the mantras are constantly circulating, but it is the Buddhist Taoism of the Great Lei Yin Temple that Lin Feng obtained from the lottery system in the past, and he does not move the Ming Wangjue.

The Immovable Ming King Recipe obtained from the system that day, only the upper part, and later killed the empty law monk in the Black Cloud Underground Palace, and Lin Feng got the complete Immovable Ming King Formula.

But at this moment, he did not release the full version of the Dao method, but still gave only the upper part of the immovable Ming Wang Jue.

Under the action of Lin Feng's mana, these scriptures condensed into a Buddhist scripture with a purple cover and gilded characters, which fell on the bookshelf.

Lin Feng patiently observed for a moment, but the Buddhist scriptures did not change, and the bookshelves and stacks themselves did not react.

After thinking about it, Lin Feng poured his mana into the bookshelf.

At this time, the flow of aura inside the bookshelf suddenly changed, and the original trajectory laws were changed, and after absorbing and transforming Lin Feng's mana, it was injected into the Buddhist scriptures on the bookshelf.

The Buddhist scripture suddenly changed, and the scripture that was originally a physical body was surrounded by purple light, and gradually turned into a cloud of virtual shadows.

The volume of the phantom is gradually increasing, and countless runes in the purple light are beating, merging into the phantom, and when the purple light is gone, the phantom reverts into an entity and changes back to the appearance of the scriptures.

But at this moment, the Buddhist scriptures are significantly twice as thick as before.

Lin Feng opened the Buddhist scriptures and saw that what was recorded in them was already a complete version of the Fudo Ming Wang Jue.

"Is that all?" Lin Feng looked around at the full bookshelves in the stack, frowned slightly, put down the scriptures, and came to the center of the stack on the first floor.

A magic circle here was quietly emitting a gentle light, Lin Feng stepped into the magic circle, the light suddenly became dazzling, and the next moment Lin Feng had been teleported to the second floor of the library of the Tibetan Scripture Building.

Unlike the first floor where the shelves are full, the second floor is extremely empty, and there is nothing in the large space.

Lin Feng walked all the way to the wall, and saw that there were many sub-scrolls hanging on the wall, but these unfolded scrolls were all blank, and nothing was written.

After quietly perceiving the aura of these scrolls, Lin Feng raised his hand and pointed at it, and another purple light shot out and landed on a blank scroll.

Many turquoise graphics appeared in the purple light, which kept beating, and as soon as they landed on the scroll, they quickly blended into it.

On the scroll, which was originally blank, a picture suddenly appeared, and the green mountains and green waters were lifelike.

Lin Feng's divine sense entered the picture scroll, and the scenery in front of him suddenly changed, as if he had really entered a turquoise world.

In this world, the turquoise Taiyin True Water flows quietly, and just by being in this environment, you can comprehend a little bit of the true meaning of the Taiyin True Interpretation Method, and comprehend the mystery of the Taiyin True Water, a spiritual creature created by heaven and earth.

Lin Feng's divine sense withdrew from this worldly realm, and his finger pointed at another blank scroll next to him, and another purple light shot out, and this time in the purple light, golden pictures and texts flashed.

As soon as the purple light came, the second scroll immediately changed, and the blank scroll appeared with a figure of the scorching sun shining in the sky.

Lin Feng's divine sense entered it, and his eyes were full of golden, bright and shining sun true fire gods, and in this golden light world, he could clearly feel the raging heat of the sun's true fire, and the mysterious mystery of the Great Sun Tianhuang Dao Classic.

"These scrolls can create a virtual space according to the recorded Dao Dharma, a space that is completely composed of the true meaning and mystery of the Dao Dharma. ”

Lin Feng had fully understood at this moment: "Practicing this unique Dao method in such a space can get twice the result with half the effort and greatly improve efficiency." ”

This discovery made Lin Feng satisfied, and he was not busy filling these scrolls, but went directly to the third floor.

The first floor and the second floor have their own wonderful uses, and I think the third floor will be even more wonderful.

Coming to the third floor through the magic circle, looking at the scene in front of him, Lin Feng was slightly stunned.

The area of the third floor is much smaller than the first floor and the second floor, the layout is simple, that is, a few bamboo tables, a few bamboo chairs, through the fence, you can clearly see the world outside the Tibetan scripture building.

There is nothing strange about it, the ordinary one is like the attic of the world.

Lin Feng naturally didn't think that the third floor of the Scripture Hidden Building was really so ordinary, he used his own mana to explore, and he actually had a feeling of hitting a wall.

Frowning slightly, Lin Feng came to the edge of the fence and looked into the distance.

The Danfang was next to it, and in the distance was the Xuantian Treasure Tree, which was as thick as a city, and below the treasure tree, Zhu Yizheng was sitting cross-legged, and in front of him were more than thirty new disciples.

Obviously, Zhu Yi has entered the role and is teaching them the Tao.

Lin Feng smiled slightly, gently touched the railing built by the purple bamboo of the scripture pavilion, and his mind merged with the entire scripture building, and gradually felt a little clue.

"It seems that I will not be able to fully exert the magic of the third floor of the Tibetan Scripture Building until I advance to the realm of the Yuan Shen. Lin Feng felt something in his heart and shrugged his shoulders: "That's it, for now, the first two layers are enough." ”

Just pondering, Lin Feng's mind suddenly sounded a system prompt: "The system upgrade is complete, and the lottery system and exchange system can already be used." ”

Lin Feng's spirit perked up, and his consciousness immediately entered the lottery system.

But this time it wasn't a direct entry, and the first thing that caught your eye was a system prompt.

"When the system reaches the third level, the host will get the latest benefits, and at the beginning of each month, they will automatically get a chance to draw a lottery!"

Lin Feng was stunned for a long time before he came back to his senses, but his first reaction was not happy, but full of vigilance.

Nima, there shouldn't be some conspiracy on the part of the system, right?

In view of the virtue of this system in the past, Lin Feng was not afraid to speculate on it with the greatest malice.

After carefully looking at the system description, he found that he didn't seem to be playing any word games, and it didn't look like there was a trap, Lin Feng was surprised: "The sun is coming out in the west?"

Unfortunately, it's past the beginning of May, and if you want to verify whether the system is actually a conspiracy, you will have to wait until June.

"Well, we'll see what tricks you play. After Lin Feng thought about it, he put things behind for the time being, and his consciousness entered the lottery system.

Let's use the two lottery opportunities from the apprentices first, and then talk about it, there should be no problem with these two lottery opportunities.

Lin Feng first entered the roulette system that he grasped the most, and after taking a closer look at the extracted items, his eyes suddenly lit up: "This thing is good!"

The Heavenly Spirit Deficiency Pill can improve the user's talent for cultivating the Dao, and it is effective when taken for the first time.

When Lin Feng saw this thing, his eyes suddenly couldn't be taken off.

"With the function of the Danfang to reverse the Danfang through the pill, if I can get such a Heavenly Spirit Deficiency Pill, I can completely mass-produce this kind of pill. ”

Lin Feng did not hesitate, immediately aimed at the Heavenly Spirit Deficiency Pill, and began to turn the roulette wheel to draw the lottery. (To be continued......)
