In the next few days, Lin Sen used almost all of them for alchemy, and as for the herbal materials, he picked them all in Song Fang's courtyard. [Ran^Text^Library] And Song Fang, as early as a few days ago, had passed the three-grade residence assessment and lived in a higher-level residence, and was currently refining the four-grade pill with all his might, impacting the four-grade residence trial.

After the last sloppy old man's guidance, Lin Sen's harvest was great, and the whole person was alchemy with another mentality, he no longer cared about success or failure as before, but regarded the boring process of alchemy as cultivation.

Now, he can skillfully control the fire, and moreover, surrounded by a spirit gathering array around him, often in the process of alchemy, he urges the rich spiritual energy around him to be injected into the Dan furnace, and the success rate has suddenly increased a lot, refining a first-grade pill, nine times out of ten can be successful, and Lin Sen also tried to refine a second-grade pill, but it still can't be refined.

At this time, he failed to refine the second grade pill again. Lin Sen pondered a little, he analyzed, there is no problem with the control of the fire, the key is that the aura increases the success rate of alchemy, obviously the higher the quality of the elixir, the smaller its effect.

"It seems that the effect of aura can only increase the success rate of the first-grade elixir, for the second-grade, the effect is very small, I don't know if the spiritual stone bricks or spiritual stone pillars obtained from the place where Yizun sits, can its aura increase the success rate of the second-grade elixir" Lin Sen thought about it, and as soon as he slapped the Qiankun bag, the spiritual stone pillar immediately flew out and suddenly appeared next to the Dan furnace. A majestic aura emanated, and the entire courtyard was immediately filled with extremely rich aura.

Lin Sen once again took out a few herbs and put them into the Dan Furnace, these herbs were the materials for refining the Second Grade Spirit Dana Spirit Pill.

This Na Ling Pill can refine nine grains in one furnace, and its refining time takes a whole day. After everything was ready, Lin Sen took a deep breath, controlled the earth fire and began alchemy.

The alchemy process proceeded in an orderly manner, and Lin Sen sometimes urged the surrounding aura to be injected into it, and in this way, until late at night, a rich Dan fragrance finally wafted out of the Dan furnace. Lin Sen knew that this was a phenomenon that was about to become Dancheng, and the more it was so, the more critical it became.

Lin Sen had a normal state of mind, and when he controlled the fire for the last time, the fire reached its strongest, and at the same time, Lin Sen urged the surrounding aura to be injected into the Dan furnace with all his might, and all this was a breath of time.

After a breath, the earth fire was extinguished, and at this moment, pills floated out of the Dan furnace. Lin Sen's eyes were overjoyed, he put away the pill, unfolded his right hand, and counted carefully, and found that there were five second-grade Na Ling Pills!

Although he couldn't refine nine yet, he had really refined the second-grade elixir now! The excitement in his heart was beyond words, this was the only time that Lin Sen had successfully refined the second-grade elixir in the past six months, and he had failed countless times during the period, and finally got a successful reward.

Lin Sen hadn't been so excited for a long time, he felt that all this was not easy to come by, and when he took the first pill in the Hanlan Forest, the feeling of surprise was still vivid. Who would have thought that after many years, he would be able to refine the exact same elixir, this kind of mood cannot be experienced by outsiders.

Soon, Lin Sen's excited heart eased, and he suddenly discovered that although he could refine a second-grade spirit pill in this way, there was a drawback.

When alchemy, it is impossible for Lin Sen to take out such a spirit stone pillar, not to mention that the spirit stone pillar, even if it is a spirit stone, it cannot be shown at will, so how can he refine the second-grade pill.

"Can you put these spirit stones in a bottle in liquid form and drip them in when you use them?" Lin Sen thought about it again and again, but there was no good way.

"Demon thief!" Lin Sen immediately called.

At this moment, I saw Lin Sen take out another Qiankun bag, and a whirlwind flew out of it, and the demon thief immediately flashed out. After he appeared, his consciousness swept away, and his surroundings were immediately clear.

"Lin Daoyou, what is the so-called thing next?" The Demon Thief's expression moved, and he quickly noticed that the feeling that Lin Sen gave him was very different from before, and as for the difference, the Demon Thief couldn't say it for a while.

"Demon thief, this place is the Dan Holy Sect, Lin is already a disciple of the Dan Holy Sect, and he is currently cultivating the art of the Dan Dao. Now there is a problem, Lin wants to turn the spirit stone into a spirit night, I wonder if there is such a possibility?"

The demon thief's heart moved, he didn't expect Lin Sen to be able to enter the Dan Holy Sect, you know, back then, he had the idea of the Dan Holy Sect, and after many attempts by him to sneak in, all of them ended in failure, and finally came to a conclusion that if you want to enter the Dan Holy Sect, the only way is to worship the master.

But it's not easy to go through the assessment, the demon thief gave up the idea of stealing in the Dan Shengzong because he couldn't pass the Dan Shengzong entrance assessment, and now he entered this place by mistake, but he can no longer afford the idea of stealing back then.

Lin Sen saw that the demon thief looked strange, and couldn't help but say in a deep voice: "Before Lin Mou has a foothold here, you'd better not have other ideas, otherwise Hugh blames Lin for being ruthless." ”

The demon thief laughed dryly, he didn't even dare to say it, he groaned slightly, and suddenly said, "Do you remember the old man's purple spirit gourd?"

Lin Sen thought about it carefully, he didn't say a word and immediately slapped the Qiankun bag, and a purple gourd suddenly flew out of it, this gourd had helped Lin Sen escape the pursuit of countless flying insects in the place where Yizun sat down, and even took some away.

The demon thief took this purple spirit gourd and said with a slight smile: "The purple aura in this gourd can attract some spirit beasts and soul bodies, in addition, all the things that are collected by the gourd will instantly turn into liquid, and as for the soul things, they will be scattered." However, as for whether the spirit stone can be absorbed, I really haven't tried it. If it can be absorbed, it may be liquefied. ”

Lin Sen took the gourd and shook it gently, and there was a slight sound of liquid hitting in it, which melted after absorbing those terrifying flying insects.

In the Yizun Cave Mansion, each of the terrifying flying insects in the robbery cave has the strength above the Dan stage, and some even have the breath of a primordial infant. I just don't know if these liquids have any effect after they are melted into liquids.

After a little silence, Lin Sen pulled out the wooden stopper, and under the slow urging of spiritual power, he cautiously poured out a drop of liquid.

I saw that this drop of liquid was milky white, and from the white liquid that Lin Sen had flowed from the injured giant flying insect, it could be inferred that these liquids might be their blood.

At the moment when this drop of white liquid appeared, Lin Sen immediately spit out a mouthful of Dan Qi to wrap it. With a sweep of his divine sense, he found that this drop of milky white liquid exuded an aura that was not weaker than that of the middle stage of the Yudan.

"Sure enough, if the thing melted in the gourd, its liquid still retains the original power of this thing, if the spirit stone is put into it, it may really be able to appear in the form of liquid, and it can also maintain its original spiritual energy. Lin Sen was pleasantly surprised, and he felt that this thing was indeed a rare treasure. At the same time, he also felt the slight fluctuations on the Demon Thief's face, after all, this thing had been the Demon Thief's belongings.
