Yun Qing returned to the cave mansion, and once again recalled the old man's alchemy technique, in his memory, that skillful technique, all kinds of elixirs emerged in endlessly, although this memory has been integrated with himself, but Yun Qing never dared to directly use this alchemy technique.

"Lan Qingxin, have you ever heard of being able to store memories?"

"There are shadow stones that can store images, and sound transmission jade talismans that can store sounds, both of which can be stored for a long time, and I haven't heard of storing memories yet."

"Okay, you have a good rest" Yun Qing didn't have any ill will towards the old man, but he sent himself on this path of cultivating immortals, how much Yun Qing was a little suspicious, he couldn't return to Cangzhou now, so he would talk about it later.

Yun Qing meditated for an hour, heard cheers in the sect, walked out of the cave, and found that there were more than a dozen copper incense burners of all sizes placed in the sect, could this be the Dan furnace that Wu Wei bought?

Yun Qing hurriedly stepped forward and came in front of Wu Wei, "Fellow Daoist, is this the Dan furnace, there is no top cover, how to condense the medicinal power to refine it into a Dan?"

"Senior, this was originally an incense burner, and the top cover is also being prepared, it should be delivered to the door in a few days, and it will not be too late to start alchemy at that time."

"Fellow Daoist, do you know that the wall of this incense burner is thick, and you can't do alchemy with your fire spirit recipe at all, if you want to use this kind of furnace, you still need to practice for a while, and you can't do alchemy in a short period of time."

"Thank you seniors for your advice, these incense burners are of the best quality in this mountain village, and it doesn't hurt to have a later time, so you can temper their hearts."

"Okay, after the top cover is ready, I'll help you refine the Dan furnace again, so that they can quickly refine the Dan, I'm going to retreat, and when the top cover is ready, just knock on the door."

"Yes, Senpai"

Yun Qing returned to the cave and began to practice immortality, Yun Qing has only reached the first layer now, but the role makes Yun Qing happy, if he can reach the ninth layer, it will really be immortal, two days, there has been no gain, Yun Qing took out the jade slip, took out the formation given by Guan Chengtian, the Xuanguang Array and the Little Seven Star Killing Array, and basically mastered the core of the two formations, Yun Qing wanted to combine the two formations into one, and build a new formation, a new formation Xuanguang Killing Array, which can trap the monks in the formation, and can use the power of the killing array to punish the people who enter the formation。

In two months, the Xuanguang Killing Array had a prototype, during which Wu Wei was heard knocking on the door, but Yunqing was in a hurry, and did not go out until the Xuanguang Killing Array was completely integrated, and then left the cave, and many people in the door could already use the incense burner to refine Bigu Dan.

Yun Qinglai was in front of the main hall of the sect, and all the disciples got up to salute, "I have seen the predecessors" Yun Qing raised his hand and signaled, "Today, I will help you refine the Dan Furnace, so that you can refine the next spirit pill" directly cast the Xuanhuo Realm, took the Dan Furnace into the Xuanhuo Realm, and used the huge Xuanhuo Realm to quench the Dan Furnace, the original rusty bronze all fell off, and the Dan Furnace also shrank a lot, driving out all the impurities, like a brand new Dan Furnace, and the Dan Furnace was still in front of everyone.

"Ladies and gentlemen, although these Dan furnaces are ordinary Dan furnaces, after quenching, they can be easily refined to lower the spirit pill, tomorrow I will go up the mountain to get some stones, and engrave the Dan Fang on the stone tablet for your reference" Then he stopped everyone from giving gifts.

Yun Qing came to the east wing, Yun Yu was still able to walk, Yun Qing bent down and stretched his hands, "Yun Yu, Daddy is here" Seeing Yun Qing, Yun Yu turned around and walked directly to the woman, several people smiled, Yun Qing hugged Yun Yu "I am going to retreat for a year, during which Yun Yu will entrust you"

"Don't worry, it's just like our children"

Yun Qing nodded, out of the east wing, leaning on the top of the mountain, looking for a suitable bluestone, half a day to find a good stone, Yun Qing split the stone into a stone tablet, and carved a variety of lower grade pill pills on the stone tablet, thirteen stone tablets, only to put nearly a hundred kinds of lower grade spirit pill pill recipe method fire, the amount of medicine is completely engraved on the stone tablet, and all the heat is according to the ordinary Dan furnace, after the carving is completed, the stone tablet will be included in the space, return to the sect, and the stone tablet will be placed on the left and right sides of the main hall.

In the eyes of Yunqing, birth, old age, sickness and death are the way of heaven, even if you keep a skin, it doesn't make much sense, even if you are immortal for life, what is the use, you can't escape life, old age, sickness and death, and finally it will turn into ashes and disappear between heaven and earth。

Yun Qing returned to the cave mansion and began to watch the alchemy techniques and various pills in his memory, and it took several months to count the refined pills in them, 710 kinds of medium-grade pills, 320 kinds of high-grade pills, and 110 kinds of immortal pills, most of which contained demon pills and magic pills, of which only 32 kinds could be taken by human monks, and there were no other memories in his memory except for alchemy.

After sorting out the pills in his memory, with Yunqing's current cultivation, I am afraid it will take thousands of years to refine all the pills in his memory, and most of them Yunqing has never seen before, let alone refined.

After that, Yunqing began to practice the Red Sea God Slaughtering Method, condensing the mana needed by the Xuanhuo Realm, which was extremely huge, and wanting to condense a stronger Xuanhuo Realm could only be done after being promoted to the realm, and then Yunqing was refining the Zhongpin Pill, among which the most concerned was the Immortal Pill, which can increase the monk's longevity for three hundred years.
