Materials other than the attributes of the five elements are very rare, and even in this sea of delusion, Lei Jing is not common.

Li Qingshan, a monk from the mainland, knew the usefulness of Lei Jing, and Yang Tianmu, as a local refiner, could understand the value of Lei Jing even more, and it was normal for him to be willing to pay such a big price in exchange for Lei Jing.

There is no need to collect other materials to refine the Flying Knife Magic Weapon, Li Qingshan is naturally very happy, but he is worried that the materials used by Yang Tianmu are not good enough.

"Yang Daoyou, what materials do you plan to use to refine this flying knife magic weapon. After a little thought, Li Qingshan asked.

"Ye Daoyou doesn't have to worry that Yang will cut corners, and Yang will use auxiliary materials for more than five hundred years. In order to strengthen the toughness, Yang will also add some iron essence, and will also use deep-sea glass to wrap Lei Jing, so as not to hurt the user's own divine thoughts. Yang Tianmu explained.

Iron essence is a rare refining material, and when he heard that this person would join iron refining to refine the flying knife magic weapon, Li Qingshan was immediately relieved.

"That's very good, I have twenty-nine thunder crystals here, which is enough to refine three flying knives, and the excess will be given to Yang Daoyou, and I hope that Daoyou will put more effort into it. Li Qingshan took out Lei Jing from the storage bag and put it on the table.

Li Qingshan didn't take out all the thunder crystals, there were still a few left, three flying knives were enough for him to use, and the remaining thunder crystals were not enough to refine another one, keep them, maybe they could be used in the future.

"Ye Daoyou is really a good opportunity, Yang will carefully refine this treasure to ensure that the Taoist friend is satisfied, and the Taoist friend will come to collect it after a month. Yang Tianmu carefully put Lei Jing into a box, put it in a storage bag, and patted his chest to reassure.

In this way, Yang Daoyou was tired, so Ye left first and came back next month. Li Qingshan nodded and said goodbye.

"Ye Daoyou, go slowly!" Yang Tianmu got up to send him off.

Li Qingshan didn't hand over the refining of the two magic weapons to this shop at one time, he didn't know the refining level of this shop, and after refining the flying knife, it was not too late to see the effect and then refine the Gu refining magic weapon.

As for whether Yang Tianmu would be greedy for his Lei Jing and ran away directly, Li Qingshan was not worried, Yang Tianmu was obviously living on Immortal Palmetto Island with his family. Leaving Immortal Palmetto City, where can he go, there will be no better cultivation place in the Thousand Egret Islands than here. Lei Jing, who is greedy for him, just picked the sesame seeds and lost the watermelon, this person will not be so unwise.

After leaving the Yang Refining Shop, Li Qingshan came directly to the Six Dao Pavilion.

"The little one has seen the seniors, and the seniors are invited to come in. The guys from the Six Dao Pavilion saw Li Qingshan and said very enthusiastically.

"Arrange a private room and call Master Qi over. "Li Qingshan Road.

"Okay, senior, please come with me. The man said respectfully and took Li Qingshan to a private room.

Maybe it's because the guy sees that Li Qingshan is a foundation building monk, and this time Master Qi came quickly.

"It turned out to be Brother Ye, no, it's time to call Senior Ye next, congratulations to the seniors on their success. After Master Qi came in, he was stunned at first, and then said respectfully.

"Brother Qi doesn't have to be like this, we can be commensurate with each other, with Brother Qi's qualifications, it won't take a few years to build a foundation. Li Qingshan said with a smile.

"In this way, it will be supported in the next, compared to Brother Ye, he has successfully built the foundation at a young age, and he is nearly middle-aged, even if the foundation is built here, Daoyou still has hope to win the Jindan Avenue. "Director Qi's attitude is very good, complimenting.

"Ye Mou came this time to buy a technique for the foundation building period of fire gold and water weak water spiritual roots, and by the way, to see if he could buy some elixir. Li Qingshan got straight to the point.

"This is the Dan Fang, fellow Daoist, take a look, is the elixir on it for sale?" Li Qingshan took out a book, put it on the table, and continued.

This book was obtained by Li Qingshan by killing the monk surnamed Yang, and it was recorded that the Lotus Lu Pill and the Ginseng Turtle Pill were recorded. As one of the five gates of the Immortal Palmetto, there must be these two kinds of pills, and Li Qingshan did not know about them, so he took them out.

"Brother Ye turned out to be a monk with a weak water spiritual root, he is really respectable and admirable, and the exercises are not a problem. Master Qi exclaimed, then picked up the book, opened it and looked at it, and then said: "The materials of these two Danfang are not together for a while, the same as before, some of them are taken first?"

"Which Danfang can get more together, let's take the materials of which Danfang. Li Qingshan thought for a while and said.

"Okay, Brother Ye will wait a while, and Qi will come when he goes. Director Qi nodded and walked out of the private room.

It's not that Li Qingshan doesn't want to buy more elixirs, it's that he can't spend all the spirit stones, he still needs to refine Gu refining magic weapons, and he will have to buy spirit insects in the future. Now that all the spirit stones have been spent, if you encounter spirit insects in the future, if you miss it because the spirit stones are not enough, you will regret it.

The auction is imminent, and Li Qingshan plans to dispose of some more items and reserve some spirit stones at that time. For example, the brown-red flying sword of the monk surnamed Yang, as well as the dark red shield, it is useless for him to keep it, and he can exchange it for a large sum of spirit stones.

The rest of the items, Li Qingshan didn't plan to sell them, the remaining twenty or so elixirs and the two earth dragon torsos obtained in the Taixu Secret Realm, he couldn't take enough alchemy pills himself, how could he take them out and sell them.

After a while, Master Qi came back.

He took three volumes of exercises, including the alchemy formula, Li Qingshan didn't think much about it, and spent five hundred spirit stones to buy this formula.

The elixir only gathered the four kinds of refining the Lotus Lu Pill, and it cost Li Qingshan nine hundred spirit stones. Other elixirs are not expensive, mainly the two-hundred-year-old sea lotus is more expensive, and this thing alone costs Li Qingshan five hundred spirit stones.

After completing the transaction, Li Qingshan and Director Qi said goodbye and left the Zodiac Pavilion.

On the way back to the cave mansion, Li Qingshan calculated in his heart, excluding the special pills, the cost of the pills in the early stage of foundation building was about two thousand spirit stones, and the pills in the late stage of foundation building referred to his own earth dragon torso, which was about six thousand spirit stones, and he didn't know the pills in the middle stage of foundation building, so he took a median value, four thousand spirit stones.

Li Qingshan estimated that from the early stage of foundation building to the middle stage of foundation building, it would take thirty furnaces and one hundred pills to say the least. In this way, even if you don't count the bottlenecks, it will cost at least 400,000 spirit stones to cultivate to the peak of foundation building.

If you want to break through to the Jindan stage, referring to the difficulty of the Creation Pill, refining the Lujiao Pill is equivalent to refining the pill that breaks through the Yuan Infant Stage, and the cost must be amazing.

After building the foundation, the cultivation became very difficult, the spirit stone was only secondary, and more importantly, the elixir was difficult to obtain.

Overseas resources are scarce, and it takes too long to get together the materials for a pill. It is good to say that the difficulty of refining the pill in the early stage of foundation building is not lower than that of refining the pill in the later stage of foundation building. If you're lucky, it takes two to three years to get together a document, and if you're unlucky, it's possible to get five to ten years.

It is no wonder that the highest monks in the Thousand Heron Islands are only monks in the Jindan period.

No matter how difficult it is to practice, the only way to do it is to move forward.
