Under Ma Xiao's guidance, Ye Xuan completely opened a door to the Dan Dao, and simply stopped refining or practicing today, and studied this incomplete Dan prescription with one mind.

Ye Xuan is now only good at refining Xuanyuan Dan and Tuojing Dan, so he first took these two pills as the prototype to carefully understand the characteristics of these two pills, and then no matter what kind of pill this incomplete pill was, he put on Xuanyuan Dan and Tuojing Dan, and calculated that in the second half of the night, he really made up for the two medicinal materials.

Ye Xuan didn't even expect that he really made up the Danfang, and then carefully scrutinized it, and after making sure that it was correct, he fell asleep.

The next day, Ye Xuan couldn't wait to come to Boss Liu's stall, waiting for Boss Liu to come out of the stall, not long after, seeing Boss Liu coming from a distance, Ye Xuan hurriedly ran forward and said: "Boss Liu, a few days ago, the stone shopkeeper said that if you make up for the incomplete Danfang, I can find you to exchange fifty spirit stones, do you still count?" ”

Boss Liu said: "Of course it's counted, could it be that your master has made up for the Danfang?" ”

Ye Xuan said proudly: "It's done, do you want to let the stone shopkeeper come over and take a look?" ”

Boss Liu said: "You don't need this, you can just show it to me." ”

Ye Xuan said in surprise: "You also know alchemy?" ”

Boss Liu said: "I just understand a little, hurry up and take a look." ”

Ye Xuan took out the Danfang and handed it to Boss Liu, Boss Liu carefully looked at the new two-flavor medicinal materials on the Danfang, which was indeed the same as the Danfang written on the other two, and this font looked very immature, as if it was written by a teenager, Boss Liu thought about it in his heart, and he had a plan.

said loudly: "Brother Ye, I don't think you look like a naughty boy, why did you write the names of two herbs casually and use them to play tricks on me?" ”

Ye Xuan said anxiously and angrily: "Don't talk nonsense, I thought about this for a day, how could it be written blindly, don't you want to regret it?" ”

Boss Liu laughed, and said: "Brother Ye, don't blame, there is no problem with this Danfang, I just saw the words on this Danfang, it seems to be written by a teenager, so I glanced at you, I didn't expect Brother Ye to be young, and he does have such insight in this alchemy, admire and admire." ”

Ye Xuan was revealed at first glance, and he didn't hide it, and then said: "Can't you refine the pill at a young age?" Hmph, give me the spirit stone, I still have to go shopping. ”

Seeing that Ye Xuan was still angry, Boss Liu was not annoyed, took out a storage bag, handed it to Ye Xuan, Ye Xuan took the storage bag, checked it, and after confirming that it was correct, he was about to turn around and leave.

Boss Liu said unhurriedly: "What is the little brother going to buy?" You might as well tell me, maybe I have it here, and the price will give you a discount. ”

Ye Xuan said: "I want to buy the formula for refining body fluids. ”

Boss Liu said suspiciously: "Didn't I give you a formula a few days ago?" Why buy it again? ”

Ye Xuan said: "I tried the formula you gave me, and for me, it didn't have much effect, so I thought about trying another formula." ”

Boss Liu suddenly said: "I see, I still have a quenching pill here, I don't know if Brother Ye is interested?" ”

Ye Xuan said: "Oh? How effective is the drug? And how to sell it? ”

Boss Liu said meaningfully: "If the medicinal effect is effective, it can completely practice "Copper Skin and Iron Bone" to the seventh layer. ”

Ye Xuan couldn't wait to say, "Show it to me." ”

Boss Liu said unhurriedly: "Brother Ye, let me ask you, you really have thought about it, you want to refine this "Copper Skin and Iron Bone". ”

Ye Xuan was puzzled: "Is there something wrong with this exercise?" Not suitable for cultivation. ”

Boss Liu said: "It's not that this exercise can't be cultivated, even if it's an ordinary person, according to the description of the exercise, and with the refining of body fluids, basically you can refine to the third layer within a month."

In the first three layers of cultivation, there is no barrier, but in the fourth layer, you can only cultivate with the Quenching Pill, and in the seventh layer, you need another kind of pill. ”

Ye Xuan said, "What kind of elixir do you need after the seventh layer?" ”

Boss Liu said: "What you need after the seventh layer is an ancient pill, let me tell you, this pill you made up is part of this ancient pill." ”

Ye Xuan suddenly said: "No wonder I am willing to give up fifty spirit stones to gather this Dan Fang, then this Dan Fang is incomplete, that is to say, the 'Copper Skin and Iron Bone' can only be cultivated to the seventh layer?" Isn't it basically impossible to cultivate above the seventh layer? ”

Boss Liu said: "That's right, you can only practice to the seventh layer." ”

Ye Xuan said disapprerovingly: "Then it's not bad to practice to the seventh layer." ”

Boss Liu took a breath of talk and said: "But after practicing to the seventh layer, if there is no inch of progress in this exercise, there will be a reverse flow of qi and blood after decades, and the body will explode and die." ”

Ye Xuan was shocked: "Why is this happening? ”

Boss Liu explained: "This exercise should be evolved according to the exercises of the demon race, although this "Copper Skin and Iron Bone" was created by the human race, but in the final analysis, it is still imitating the structure of the demon race, in ancient times, there are abundant resources and spiritual energy, and it is not difficult to cultivate "Copper Skin and Iron Bone".

But now there is a shortage of resources and a lack of elixir, so it is difficult to practice this exercise to achieve great success, but there was a monk before, when he fought with people, his cultivation was abolished, and he got this "Copper Skin and Iron Bone" by chance, this abolished monk had to practice, with the desire and opportunity for revenge, this person really cultivated to the seventh layer, and then he looked for the enemy to take revenge, at this time the enemy was already the cultivation of the middle of Jindan, that person dressed up, looking for an opportunity to approach the enemy, and took advantage of the enemy's unpreparedness, and finally killed him with serious injuries.

Later, this person became famous, so he opened a small sect to teach people "Copper Skin and Iron Bone", and at the same time arranged for disciples to go to various places to find exercises and pills that could make him go further, but he couldn't find it for several years.

About another fifty years later, this body refiner, suddenly the whole body of blood retrograde, exploded and died, before dying, the disadvantages of this exercise told the disciples of the sect, and then the disciples of this sect, the disciples above the third layer all had the situation of blood reflux, barely a few disciples who cultivated to the profound, wanted to rely on cultivation for suppression, although they survived for several years, but still could not get rid of the tragedy of blood reflux. ”

Ye Xuan had already cultivated to the fourth layer, if according to what Boss Liu said, wouldn't he be a few decades later, he would also explode and die, Ye Xuan panicked.

He said angrily: "Then why do you still sell this trick man's exercises? ”

Boss Liu said with a slight grievance: "That exercise with the body refining liquid, at most you can cultivate to the third layer, if you want to practice to the fourth layer, you must take the body quenching pill." And in this city, there will be a Quenching Pill here, and even if this exercise is practiced to the third level, there will be no other side effects. ”

Ye Xuan said: "Then wouldn't it be better for you to directly sell the exercises of the first three layers?" ”

Boss Liu asked rhetorically, "Would you buy exercises with only three layers?" ”

After speaking, Boss Liu looked at Ye Xuan carefully, and carefully looked at Ye Xuan's exposed skin.

Suddenly startled, he grabbed Ye Xuan's arm and said, "Isn't it that you have already cultivated to the fourth layer?!" ”
