Lu Yi looked at this headless couplet strangely, how could he not connect this couplet with this skeleton and the challenges he had to face, could it be that he wanted to refine his own medicine to resurrect this skeleton? This is too, it is impossible to do it, not to mention Lu Yi, even the top Dan master in the mainland may not be able to do it. So what does this mean? Lu Yi sat in front of the couplet and pondered, but he didn't have any idea at all.

Something must have been missing! Lu Yi got up again and began to search carefully in the room little by little, there was nothing noteworthy on the room and the four walls, so he jumped to the skeleton of the giant beast again to find, this time, he was much more detailed, every bone was carefully looked at, sure enough, Lu Yi found that many bones were hidden with a paragraph or a few words, some were obviously Danfang, some were some alchemy experience, but the content was not comprehensive, after reading a few places, Lu Yi found that these scattered language and words can be pieced together to form a complete Danfang and experience。 Moreover, he also found that the bones engraved with the words seemed to have loose marks, as if they had been artificially inserted later. So Lu Yi began a bold move: he removed all the bones with words from the skeleton of the giant beast, and then he began to piece together those text fragments according to his own judgment, striving to make a complete Danfang or experience.

This jigsaw puzzle-like test is still very interesting, Lu Yi was completely attracted to it unconsciously, he focused on the splicing attempt, and unconsciously knew all those words by heart. After tossing for a while, Lu Yi stopped what he was doing, first divided the words into two parts in his mind, one part was the content of Danfang, and the other was the content of his experience, took off a tiger tooth from his waist, and carved out all those words on the ground according to his own understanding. Then, Lu Yi erased some words that felt incoherent, and adjusted the order from the beginning, until he felt that the words were completely smooth, and then put those bones corresponding to these words under each line of words.

Looking at his masterpiece, Lu Yi felt a lot more relaxed, and temporarily forgot whether the ban was opened, but calmed down and sat on the ground and began to seriously comprehend this Danfang that he spliced out. This is a miraculous elixir, and its effect is extremely similar to that of the reincarnation pill of life and death, just like that couplet says, it has a miraculous ability to resurrect the dead. And the main material of this Danfang is the huge skeleton in front of him, a rare seventh-order sea beast called the Sword Whale. This sea beast called sword whale has a similar ability to regenerate the severed limbs of the octopus demon beast, relying on a very small amount of liquid secreted in its body, this liquid can only produce a tea bowl of amount per year, all of which are stored in the sword whale's demon pill, when a certain part of its body is injured and missing, it will force out some of these liquids from the demon pill, and transport it to the wound location through the circulation of blood, under the action of this liquid, the missing part will slowly regenerate. As long as its main organs are not missing and do not kill it instantly, the sword whale can basically give itself a new life through this magical liquid.

After learning about this magical ability of the sword whale, the owner of this secret realm went to the chaotic overseas sea for a thousand years, captured hundreds of sword whales for research, and finally allowed him to successfully refine the elixir called "Ghost Seeing Sorrow" recorded on the Dan Fang, which means that with this pill, the little ghost doesn't want to take away people's lives. Unlike the Reincarnation Pill of Life and Death, the medicinal effect of this Pill is relatively mild, there is no restriction on the level, anyone can take it, and although the sword whale is rare, it is much more common than the Yin Spirit Grass, and the other dozen or so auxiliary medicinal materials are not difficult to find, so Lu Yi was moved when he saw the explanation of this pill, and said that he would give the pill recipe of this pill to the success of enlightenment.

Lu Yi didn't know that after he had removed all the bones with words, the prohibition in that room had been quietly opened. When Lu Yi got up again, he was already satisfied, and finally cooperated with the experience to fully master the refining method of this Dan, if the materials at hand are complete now, Lu Yi is absolutely confident that this "ghost sorrow" will be refined, he can't help but look forward to it, one day after the Dan is really made, what will be the effect of this "ghost sorrow"?

Lu Yi looked up at the skeleton of the sword whale again, at this time his eyes were completely focused on the bone spur that grew on the head of the sword whale, this is the best material for refining spear magic weapons, if he can find a way to take it away, how good it would be! Speaking of taking this thing away, Lu Yi woke up to the fact that he was still trapped in the room, he turned his head to look at the prohibition at the door, and found that the prohibition had disappeared at some point, he was surprised and delighted, happy that he could finally go out; This kind of thing has happened more than once, fortunately, he is blessed and has not encountered danger, otherwise, he would have become a loess long ago, such a thing must not happen again in the future, with the increase of his strength, the opponent he faces is also more powerful, any opportunity is seized by others, and he is said to be a fatal threat, Lu Yi couldn't help but break out in a cold sweat.

Lu Yi finally had to give up the long bone spurs of the sword whale, because he couldn't take it away, and he didn't have a tool in his hand that could cut it off, which made him very unhappy with the money fan. Walking out of the room, Lu Yi first came to the prohibition leading to the inner layer, stretched out his hand to try it, and found that he had been able to pass the ban, it seems that as long as these five rooms pass one of them, it will be considered to have completed the test of this level, Lu Yi was a little hesitant, do you want to go over now, what he gained just now is not small, and maybe there will be good things in other rooms, Lu Yi's greedy old problem has been committed again, he is itching, pacing back and forth for nearly a stick of incense, and then finally gritting his teeth and flashing into the inner ban。 It's important to get down to business, the reward you get now is the sixth-order pill, listen to Nan Qingyun, the people of the Medicine Emperor Valley have once obtained the eighth-order pill in the secret realm, it is a sky-high price, if you can't bear it, you will make a big plan, let these little things go first this time.

After entering the inner floor, nothing happened, the inner floor is just a vast hall, there is a staircase leading to the second floor on the left and right, Lu Yi looked around, and found that there are also four prohibitions on the first floor, which should correspond to the four doors outside, he walked up to the second floor and found that there was a circle of eight houses on the second floor, but there was no staircase leading to the third floor.

According to the old rules, Lu Yi chose a room in the middle of the two stairs upstairs, flashed and walked in through the prohibition.

This room is not so much used for breaking through, but rather as a study room, because there are more than ten museum shelves in this room, and a number of jade boxes, wooden boxes, iron boxes and other things are placed on each museum shelf, as well as a lot of jade slips. In addition, there is a desk and a stone chair in the room, all of which are made of high-quality jade. Lu Yi walked around the room, still didn't find anything related to the test and challenge, the ban in the room was also closed, he was bored and opened the various boxes on the museum shelf one by one, and found that all the stored in it were rare elixirs, Lu Yi could recognize a lot, these pills are very valuable, any of them can be seen on the market can cause a rush. Lu Yi's eyes lit up, and he couldn't wait to take all these things away, but seeing that he had nothing to use to hold these boxes, Lu Yi couldn't help but scold the owner of this secret realm in his heart, isn't it obvious that it makes me addicted to it and is in a hurry? How can anyone be so vicious in his mind?! After reading these boxes, Lu Yi sprinkled his anger on those jade slips again, since the pills can't be taken away, then I'll take your pills in my mind and take them out, these things don't need to be stored, I can always take them, right?! Thinking so, Lu Yi casually took a jade slip from the museum shelf, and then sat on the stone chair with his ass, intending to see what was inside the jade slip, but the moment his butt touched the surface of the chair, a flash of spiritual light flashed, and Lu Yi was teleported out with the chair.

Lu Yi didn't have time to deal with it at all, and he couldn't react at all, because the chair seemed to have a kind of suction, firmly sucking Lu Yi on it, and at the same time imprisoning Lu Yi, making him unable to make any moves to resist. This teleportation is very short, almost a blink of an eye, Lu Yi is now in a Dan room, there is a Dan furnace more than one person high on the ground in the middle of the Dan room, Lu Yi stepped forward to carefully observe and touch, this Dan furnace turned out to be a treasure, it can be seen that the master of this place is big. In the corner of the Dan room, there was a huge box, Lu Yi tried to open the box to see the contents of the box, but found that it was not possible to use manpower at all, and he had to use spiritual power, but Lu Yi's own spiritual power did not dare to consume too much, so he still held back and did not open the box, although he guessed that there should be some alchemy materials inside, and this level is to use the Dan furnace to alchemy.

Lu Yi lifted the jade slip and looked at it for a while, deciding to see what was recorded inside, he probed his spiritual power into it, and he was stunned after looking at it for a long time.
