When it came to the fifth medicinal herb, Chu Yulong could be regarded as handy, not only did he purify the fifth medicinal material, but the quality of the intersection was much better than the last time. Chu Yulong breathed a sigh of relief, and the successive failures were not a small blow to Chu Yulong.

In the end, Chu Yulong consumed all the ten medicinal materials, and at this time, he succeeded six times with the most medicinal materials, and the least one also had three times, which was excellent among the alchemists that Chu Yulong knew. It's just that Chu Yulong's alchemy talent can't be prematurely determined, after all, there are still many steps to be done in the future.

Chu Yulong sat cross-legged on the futon in front of the Dan furnace, quietly spitting. Although these medicinal materials are all low-level medicinal materials, and even many of them can be used by ordinary people who have not cultivated, but they cannot hold up a large amount. Seventy medicinal herbs came down, even if the Chu Imperial Dragon Essence and Qi were alternated in turn, the consumption was not small.

After the medicinal materials are purified, the process of alchemy is half completed. It's just that Chu Yulong knows that Cheng Dan is a process of refining various medicinal materials into a whole, and if he is not careful, he will lose all the plates.

Threw all the purified products into it, but except for the two medicinal herbs, the others were divided by Chu Yulong with flames.

A few drops of clear liquid encased some gray powder, slowly baked by the flames. Perhaps because of the temperature, the powder seemed to be melting and gradually fused with the liquid. However, in the end, about a quarter of the powder could not be melted into the liquid, and the liquid was not transparent anymore, but very cloudy.

Seeing this, Chu Yulong let go of a flame and used his mortal knowledge to push another powder over and mix it with the liquid. The strange thing is that when the powder and the liquid come into contact, they make a "sizzle" sound, as if the two are repelling each other. Chu Yulong had been prepared for this situation for a long time, and immediately increased his firepower. I saw that when the two were repulsed, there was also fusion, although the fusion was very slow. Seeing this, Chu Yulong increased his firepower again, but this time he didn't control the strength well and directly turned into flying ashes.

Chu Yulong was a little nervous, there was an uneven pill in the Dan furnace, and there was a cloud of liquid on its outer layer. It's not that Chu Yulong feels sorry for the medicinal materials for refining medicine, but because this is the last of his ten medicinal materials, if it fails, he has no choice but to give up alchemy.

Slowly roasting the pill with a warm fire, this last time Chu Yulong failed at this step, and this time he naturally didn't dare to be sloppy. Danmaru had already begun to soften under the persistent scorching of the flames, and seemed to be heading in the direction of melting. This change was naturally discovered by Chu Yulong, who had been paying close attention to the pill, and saw that Chu Yulong used his mortal knowledge to sprinkle the liquid next to the pill directly on the pill.

Seeing no change in the liquid and the pill, Chu Yulong chuckled in his heart, thinking, "It's not going to fail again." No matter what he thought in his heart, the movements of Chu Yulong's hand were indeed not slow, and the flames surged upward, enveloping the pill. Under the persecution of the flames, the liquid also fused with the pill, and the unevenness on the pill was gradually smoothed by the liquid.

After all the liquid was integrated into the pill, Chu Yulong did not withdraw the flame, but lowered the temperature of the flame slightly, and continued to scorch the pill, and after about ten minutes, Chu Yulong lowered the flame and extinguished. At this time, what appeared in front of Chu Yulong was a round, red elixir.

Chu Yulong took out the pill from the pill furnace, put it in his hand, and looked at it carefully. This pill was not perfect, and even the color was a little dark, but this did not affect the joy in Chu Yulong's heart, after all, this pill was the first pill he had successfully refined.

After playing with it for a while, Chu Yulong put the pill into the storage container, planning to take this pill tomorrow to find a respected alchemist to apprentice. Night Frost was waiting for Chu Yulong in the dormitory, he knew in his heart that this day was very important to Chu Yulong, although he couldn't help Chu Yulong do anything, but he could wait for Chu Yulong to come back.

Chu Yulong was not surprised at all that Night Frost was waiting for him to come back in the dormitory. Night Frost is not good at talking on weekdays and won't say some good things, but Night Frost has been expressing her concern with actions, even if it is some small things.

Chu Yulong said to Night Frost quite excitedly: "Night Frost, my elixir has been successfully refined. Tomorrow, I can go to Zhou Lao to apprentice. "Zhou Lao is Chu Yulong and Ye Shuang's teachers who have been carefully selected during this period of time, although the level of alchemy is not the strongest in Ye Feng Academy, but it is also in the top ten, the most important thing is that this is Zhou Lao's teaching ability is very strong, and he has the grace of guidance to many alchemy masters.

Chu Yulong didn't practice this night, but chose to sleep. After all, when he goes to apprentice tomorrow, his mental outlook is also difficult to import, and although cultivation can replace sleep, with Chu Yulong's current cultivation, if he cultivates overnight, he will inevitably be a little unenergetic tomorrow.

It's just that Chu Yulong planned very well, but he didn't fall asleep in a daze until late at night. The next morning, Chu Yulong got up early, washed his face and looked in good spirits. Ye Shuang didn't accompany Chu Yulong to apprentice, and Ye Shuang himself was about to take the test of auxiliary industry, and then he also needed to apprentice with his results, and now he naturally can't be sloppy.

When Chu Yulong came to Zhou Lao's door, he was told by the medicine boy that Zhou Lao was refining a pill and needed Chu Yulong to wait outside the door. Chu Yulong secretly said in his heart: "I happened to meet Zhou Lao's alchemy, and my luck is not very good." After listening to the medicine boy's words, Chu Yulong stood quietly outside the door with his hands down, waiting for Elder Zhou's summons. Chu Yulong reviewed the alchemy knowledge he knew in his heart, and if Zhou Lao asked him later, he would not panic.

About an hour later, the medicine boy came out and said, "Elder Zhou let you in." Chu Yulong said in a low voice: "Yes." Then he walked in with the medicine boy. After walking a few steps, the medicine boy said, "Old Zhou is behind the door, so I won't go in with Gongzi." Chu Yulong said in a low voice: "Thank you for leading the way." Then he pushed the door open and walked in.

After pushing the door open, the first thing Chu Yulong saw was Zhou Lao sitting on the futon, not having the long hair that Chu Yulong imagined, but the short hair that looked capable. Xu is has been in contact with medicinal materials for a long time, and Chu Yulong can still smell some faint medicinal fragrance. Chu Yulong took a few steps forward and said, "Disciple Chu Yulong pays a visit to Mr. Zhou. Elder Zhou said with a "hmm" and said, "Although Chu Yulong has a good cultivation talent and comes from a famous family, if you don't have enough alchemy talent, I still won't accept you as an apprentice." ”

Chu Yulong bowed down and said, "The disciple is clear. ”

Elder Zhou was quite satisfied with Chu Yulong's attitude, so he said, "Then bring me the pill you refined." Hearing this, Chu Yulong took out a jade bottle from the storage container and handed it to Zhou Laodao: "Please sir, please inspect it." ”

After Zhou Lao turned out the jade bottle, he first uncorked the bottle, sniffed it with his nose and said, "The blood return pill of the Shi rank?" Chu Yulong was shocked in his heart, and he had a deeper understanding of Zhou Lao's alchemy attainments, and said: "Mr. Wisdom, it is indeed the blood return pill of the Shi rank." After receiving Chu Yulong's affirmative reply, Zhou Lao took the pill out of the bottle and put it in his hand to examine it.
