If Qingyang is just an ordinary pharmacist's assistant, he can't learn even if he sees it. However, Qingyang was once a senior king of Lingdan. He has both vision and experience. In this process, he can remember and learn a lot. Unknowingly, the level of refining Mingdan by Qingyang has improved greatly. Qingyang feels that if he refines jimingdan now, Even if you can't meet the requirements of the disciples of Dan division, you can at least have a 20% success rate.

Not only that, Qingyang feels that his refining level of Lingdan will also be improved. The unique techniques and experiences learned these days are not only useful for refining Mingdan, but also helpful for refining Lingdan. Qingyang's elixir reached the level of the senior elixir king for a long time. Later, due to the limitation of cultivation, Qingyang's level of refining elixir has been stagnant, just as it encountered a bottleneck in cultivation. However, through this collision learning with Mingdan refining, it is possible to improve again. It is estimated that it will not be long before Qingyang can try to refine Yuanying level elixir, At this point, he went beyond the limitation of the king of Dan and became the legendary king of Dan.

As for GE Dagen, with the help of two elixir masters, Qingyang and ghost Xia, the level of elixir has also improved a lot. In short, the three people have gained a lot from this closed door alchemy.

Immortal GUI Xia is not a hard-working person. She has to stop to adjust her state every time she uses a piece of material. She has to take a special rest every time she refines several pills. Therefore, the refining efficiency of pills is not very high, and she prepares a lot of materials. It took less than half a year before she used up all the materials, and dozens of pills were refined in total.

Dozens of pills were enough to improve her cultivation from the third floor of the golden elixir to the middle stage of the golden elixir. Therefore, after the materials were used up, immortal Guixia resolutely ended the closure, ordered two maidens to open the prohibition array of the alchemy room, and they went out of the alchemy room together.

Naturally, everything in the alchemy room was left to the subordinates to clean up. Anyway, immortal Guixia couldn't do it. In less than half a year since she asked Qingyang and Ge Dagen for help, she finally rounded up an integer and gave each person 90 dark stones. Maybe it was because the alchemy results were better than expected. Immortal Guixia was in a good mood and gave each person a cold pool order.

The so-called cold pool order is a token of a forbidden area in ghost valley. With this token, immortal friars can practice in it for one month, which is very helpful to improve their cultivation.

The whole ghost Valley is located on a super large Yin vein. It is a good place for ghost friars to cultivate, but it is useless for fairy friars. It is better if there are enough pills like Qingyang. Fairy friars like GE Dagen who have little inside information stay in it for a long time. Their accomplishments not only don't improve at all, but also may retreat, If this problem is not solved, he may not have another chance to get married in his life.

There are many immortal friars in such a large sect as ghost valley. If you want to maintain the centripetal force of the sect, you can't ignore this problem. The cold pool order is one of the ways to solve it.

There is a way that things will change when they reach the extreme. The location of the ghost Valley is a super large Yin pulse, which is full of this strong Yin, ghost and ghost gas. However, at a pulse eye in the ghost Valley, there is an area that goes the opposite way. That pulse eye is a low-lying land, which is small, just ten miles away, but it has extremely strong aura and is thick attached to the depression, From a distance, it looks like a pool of water in the fairy palace. Because it is located in the pulse eye of the Yin pulse of the whole ghost Valley, the temperature of the whole depression is very low, just like cold winter, so it is called cold pool.

Therefore, this place was specially forbidden by the ghost Valley as the cultivation place for the immortal friars under the door, and the cold pool order is the token to get in and out of that cold pool. Of course, not everyone can come to such an important cold pool casually, and the cold pool order will not be issued casually. Ghost valley will give corresponding cultivation time every year as an additional benefit according to the level of fairy friars. The lowest level worker medicine boy will generally give a month of cultivation time and issue a cold pool order as a voucher for more than ten years, When in use, only give the cold pool order to the gatekeeper of Xiantan.

For pharmacists like Qingyang and Ge Dagen, only one month is given in five years, which is equivalent to one cold pool order in five years. The disciples of Danshi are given one cold pool order a year, and the guests of Danshi are three every year. Only the offerings of Danshi are not limited by the cold pool order and can go out and into the cold pool at will.

In addition to the normal distribution, the ghost Valley occasionally rewards the disciples of the cold pool order, and allows private transactions. However, the cold pool is too small to accommodate too many monks at one time, so the ghost valley will also control the distribution of the cold pool order, so as not to have too many Fairy disciples practicing in the cold pool at the same time, diluting the aura in the cold pool and reducing the cultivation effect.

For this reason, the cold pool is extremely popular among the immortal disciples in the ghost valley. It is said that the aura in the cold pool is so strong that one month of cultivation in the cold pool is comparable to one year outside, which is enough to make up for the delay.

In this case, if it were not for the extreme lack of spirit stone, who would sell the cold pool order related to his future? So it's hard to buy it at ordinary times. If you buy it on the black market, a cold pool order needs at least two or three hundred spirit stones. It's often priceless and you can't buy it with a dark stone. Immortal Guixia can always give them two cold pool orders in addition to the agreed rewards, which is enough to show how satisfied she is with the completion of Qingyang and Ge Dagen's task.

At first, Qingyang didn't understand when he received the cold pool order. After listening to ge Dagen's explanation, he knew the wonderful use of this thing. A month inside is comparable to more than a year outside. The speed of cultivation is faster than that of using elixir. It's almost as fast as when he practiced with spirit stone.

Thinking of this, Qingyang has made up his mind. After going out, he must find a way to make more cold pool orders. In the future, he will practice in that cold pool. Even if he spends more spiritual stones, hundreds of spiritual stones are very expensive for others and nothing at all for Qingyang. Such practice is not a luxury. Can it be more luxurious than practicing directly with spiritual stones? It is important to treat Yu Mengmiao, but his cultivation can't be delayed.

After paying the reward, immortal Guixia here was about to send Qingyang and Ge Dagen out of the Guixia cave. Suddenly, three friars came outside the door. The ghost beads that had not appeared for a long time led the way. Behind him were immortal Guiyun and ghost Huanzi who had a conflict with Qingyang.
