Luo Tianyan chose Dan Dao, she also appeared in a closed secret room with a stone platform, judging from the placement of these three pills, it was obvious that the people who came in before had already chosen the better pills, and only these three pills were left in the white forbidden light curtain.

One of the pills has a rare cloud pattern on it, this pill has a smooth texture, it is a top-grade Qianyuan Dan, and the other pill is a high-grade Diyuan Dan, with three Dan patterns on it, but it does not form a cloud pattern, it is just a top-grade quality. The last gray-black elixir was like a half-wasted elixir, and it looked a little abrupt when placed on the stone platform.

Whether to choose Qianyuan Dan or Diyuan Dan, Luo Tianyan was a little undecided, Qianyuan Dan is suitable for monks in the late stage of Zifu, and Diyuan Dan is suitable for monks in the early stage of Jiedan, and she can't use these two pills now.

Luo Tianyan pondered for a moment, and when she saw the gray elixir, her face suddenly showed a hint of curiosity, and she stepped forward and looked at it carefully.

Maybe it was because it had been a little longer, or maybe it was because Luo Tianyan's cultivation was low, a silver vortex slowly rotated in the secret room space, and a strong suction force pulled towards Luo Tianyan.

Luo Tianyan instantly sensed the abnormality in the space of the secret room, she reached through the white light curtain, and quickly grabbed the gray pill, at this time, a wave came, Luo Tianyan was already in a stone room seven or eight zhang large.

She carefully looked at this alchemy room, this is an excellent alchemy room, the whole is made of dock stone, which can not only insulate the high temperature of the earth fire, but also is an excellent material for draining the earth fire.

In the center of the ground, there is a superb Dan furnace magic vessel, and a grass woven futon is placed on the ground in front of the Dan furnace, and a dragon head carved by a dock stone sticks out from the stone wall on the right side of the Dan furnace, extending to the bottom of the Dan furnace.

The roof of the alchemy room was inlaid with a moonstone as big as a fist, illuminating the entire interior brightly.

Luo Tianyan looked at the entire alchemy room, and then sat on the futon in front of the alchemy furnace, only to find that a burst of spatial fluctuations suddenly appeared out of thin air in front of him, and a small silver vortex appeared in front of him, and then a jade slip and a jade box fell from the silver vortex.

Luo Tianyan stretched out his hand to grab these two items, and his divine sense penetrated into the jade slip, and after a while, he finished reading the content recorded on the jade slip, and then he understood what to do next.

She quickly opened the jade box and took out a six-leaf green grass from inside, then she took out a cyan fruit from her sleeve and put it into the jade box, then she closed the jade box and threw it into the silver vortex, suddenly, a burst of silver light flickered in the center of the vortex, followed by a buzzing sound that resounded through the secret room.

In the blink of an eye, Luo Tianyan found that the silver vortex in front of him had disappeared, and a round hole the size of a dragon's eye appeared on the ground in front of the Dan furnace, and some small formation patterns were engraved around the round hole.

It turned out that the person who was required to be tested on the jade slip must refine a high-grade Lingyuan Pill taken by a ninth-level Qi cultivator in order to pass this assessment, and the successful person will get an alchemy inheritance, while the loser will be eliminated and will be teleported out of the Ascension Immortal Palace.

Luo Tianyan took out a jade box and put the six-leaf green grass in it. It was not difficult for her to refine the top-grade Lingyuan Dan, but now she was not in a hurry to refine the Lingyuan Dan.

She took out the gray elixir she had obtained from the stone platform, put it in the palm of her hand and looked at it again, judging from the refining materials of this elixir, it contained a small amount of the essence of the six-leaf green stripe grass.

This made her even more curious, judging from all the arrangements in the Ascension Hall, the owner of the Ascension Hall was so amazing and gorgeous, and why he would leave a low-level pill that could not be successfully refined.

As her divine consciousness attached to this elixir, a picture came into her mind.

In the picture is a fragment of alchemy inheritance, only to see a hazy figure in a red dress, unable to see her face clearly, she is holding a six-leaf green grass in her hand and throwing it into the alchemy furnace.

The woman in the red dress kept changing the magic tricks, forming one magic seal after another and hitting the earth fire below the Dan furnace.

The flames of the earth fire constantly change color, sometimes large, sometimes small, and sometimes turn into various birds and beasts, which is a rare set of fire control secret techniques.

After a while, bursts of misty gas came out above the Dan furnace, and the woman hit a trick on the Dan furnace, and the Dan furnace began to rotate rapidly, and she slapped several times on the wall of the Dan furnace, and the furnace lid rose high, which was a set of methods for shaking the furnace.

I don't know when, there was an extra jade bottle in the hand of the woman in the red dress, and I saw a string of green spiritual light coming out of the Dan furnace and flying into the jade bottle.

These pills are bright in color, warm and moist as jade, and they are surrounded by a circle of cloud patterns, which are nine top-grade Lingyuan Pills.

As soon as the woman in the red dress collected the magic trick, she waved her hand towards the Dan furnace, and a gray light fell into her hand, at this time, the furnace lid also fell back to the alchemy furnace steadily, she closed the bottle cap, and then punched one magic seal after another into the gray light, and the gray light gradually restrained, revealing its true face, which was the gray pill that Luo Tianyan obtained.

The picture stopped abruptly, and Luo said that it was as if he was at the scene in person, and he watched the whole process of the woman in the red dress refining the Lingyuan Pill.

It is not so much that the woman in the red dress left behind a gray elixir that she did not know the purpose, but that what she left behind was the inheritance of refining the best elixir.

Alchemists who can refine the best elixir have a smooth path to the Dan Dao, and they will all be able to grow into alchemy-like beings in the future.

The best elixir can be encountered but not sought, and most alchemists may not be able to refine a top-grade pill in their lifetime, that is, some large forces with many alchemists can occasionally refine one or two top-grade pills.

The better the level of the same elixir, the stronger the efficacy, the key is that the better the quality of the elixir, the less erysipelas it contains.

As long as the best elixir is slightly refined, it can get rid of the trace amount of erysipelas in it, and it is often a good medicine used by immortal cultivators to break through the bottleneck.

Each level of cultivation requires a huge amount of aura, and it is too slow to absorb the free aura in the void just by meditating.

In order to improve the mana realm faster, some immortal cultivators would often be tempted to take a large amount of pills in order to break through as soon as possible.

Although most people know the truth that medicine is poisonous, there are many immortal cultivators who drink to quench their thirst.

Once the temptation is turned on, some people can no longer stop the car.

These immortal cultivators may have tasted the sweetness of the sudden increase in mana in the early stage, and as they break through several small realms, they will find that they have developed a certain amount of resistance, and the pills that can be used to break through the bottleneck are no longer effective against themselves.

At this time, they will find that the erysipelas they thought they had refined before have reappeared, and they are even more difficult.

In fact, the erysipelas they had refined before had indeed disappeared, but there were still trace amounts of erysipelas that had been hidden in some tiny meridians.

At this time, it will take more time to get rid of these erysipelas, and the so-called bottleneck will naturally arise.
