Although Lin sent medicinal liquid, the spiritual energy content inside was not bad compared to the foundation-building pill, and the impurities content was small. Ye Yi was naturally curious whether refining this way could reduce impurities.

"This is a special method passed down by my family. I can't tell you. I hope my fellow Taoists will forgive me." Lin said, without any guilt. After all, the cultivation world also emphasizes not exploring the inheritance of other people's martial arts.

"I was reckless." Ye Yi actually asked this because of excitement. Now he thought about it, it was indeed impolite. "I don't know how many such medicines can be sold for sale with fellow Taoists. We have all collected them. Can it be based on the price of the best foundation-building pill?"

"Of course, I still have a few bottles here." Lin took out several bottles, all of which were carved from spirit stones. The spirit stones are rectangular bodies with length, width and height of 3,3,5 cm, which makes it easier to use spirit stones to carve them directly when there is no jade bottle on the body.

Foundation building pill is actually a pill containing a lot of energy that can help cultivators break through. After all, what they fear most when breaking through is that they are not able to break through the bottleneck in one breath. At this time, the slow absorption and transformation outside is too slow, so they have to use the pure energy pill such as Foundation Building pill.

All types of breakthroughs are like this, the difference is just the amount of energy. You can also break through by taking some natural treasures with sufficient energy. However, the energy in the pills is relatively mild and easy to absorb and transform, while the genius treasures are different. They are not tamed. The energy is violent and can easily be injured.

The reason why monks advocate not to use elixirs to break through. First, it is best to break through. Second, there are few top-quality elixirs. If too many elixirs accumulate and completely block the meridians, then you will not go far.

However, if there are top-quality elixirs, monks will not mind using top-quality elixirs. After all, different spiritual roots can absorb spiritual power differently. Some people may take more than a decade to accumulate. Just like Zhou Hui and Xiaomei, there is basically no possibility of building a foundation, so they can only use elixirs.

Of course, this is also before the Nascent Soul. After the Nascent Soul, monks need to understand the laws of heaven and earth if they want to break through again, otherwise no matter how many elixirs are, it will be useless.

The exchange ratio of upper, middle and lower grade spirit stones is 1:100:100, but it takes 110 yuan to exchange for lower grade medium grades to exchange for 1 yuan, because of the purity.

The materials of spirit stones are the same, and they are a special material that can store and lock spiritual energy. However, the purity of spirit stones in different grades is different and the capacity is different.

Therefore, if you change to the lower grade and even the upper grade, you need to add additional products. As for why the Spirit Pearl Spirit Card is not up, middle and lower, the middle and upper grade spirit stones are very good refining materials.

It’s a long way to go. In short, the price of the best foundation-building pill is still very high. The market price is 10 top-grade spirit stones, because the energy in the best foundation-building pill is almost equivalent to ten top-grade spirit stones.

In fact, energy-type elixirs can also be used as spirit stones, but it is not convenient to not reveal spiritual energy without spirit stones.

The medicine that Lin had refined before could be divided into five parts. Xiaomei and Zhou Hui used one part, and there were three left. Later, she prepared the remaining ingredients twice, and there were 13 parts in a total of them. Each part was filled with a thumb-sized jade bottle.

After changing to 130 top-grade spirit stones, Lin asked: "Do you still receive other medicines here?"

"Of course." Ye Yi nodded.

Lin took out the remaining potions she had refined before, "This is a body-tempering enhancement potion, which can strengthen the body and simply cleanse the marrow and clear the meridians. This is a transformation potion, which can change the gender. The effect is one month, but I am not sure what cultivation is effective. This is a healing potion, which can recover quickly."

After Ye Yi opened the tasting, he took these with 70 medium-grade spirit stones. Lin was about to say goodbye and leave. Ye Yi personally sent Lin out, saying as he walked: "If you refine that foundation-building agent in the future, you can send it to our Jianwen Pavilion. We will definitely purchase it at the market price."

"Okay." Lin had no objection, after all, Jianwen Pavilion was quite fair.

When she left the store, she paused for a moment, turned around and bought several storage bags, all of which were 5 cubic meters of space, as well as defensive magic weapons and blank array flags, and bought another flying boat, spending 3 top-grade and 50 medium-grade spirit stones.

After leaving Jianwen Pavilion, he saw Zhou Hui and Xiaomei who were waiting anxiously across the street, and hurriedly walked over.

"How is it?" Zhou Hui asked, the latter nodded and immediately laughed.

After that, they did not pause and went directly to the teleportation tower and chose to teleport Yishan City. They said it was teleportation, but in fact they did not arrive at the destination in the next moment. They would spend different time depending on the distance.

From here to Yishan City, I stayed in the teleportation array for about ten minutes. After coming out of the teleportation tower of Yishan City, the three of them felt relieved because they completely got rid of the Bai family.

"Eat something first, rest for one night and then set off tomorrow." Lin suggested to Zhou Hui.

"Okay." When he arrived here, Zhou Hui was no longer so anxious.

During the teleportation, Lin said how much spirit stones she had earned, so Zhou Hui and Xiaomei would not feel cash-strapped, so the three of them started shopping on the street.

As the city closest to the mortal world, Yishan City is still quite prosperous, although there are not many spiritual veins here. After all, every three years of recruiting disciples, people from major sects will go to the mortal world through here.

It was a coincidence that Lin and the others happened to be recruiting disciples in the past three years. Then, they also learned something. It turned out that the mortal world did not enter as soon as they wanted to. The mortal world is usually closed to people in the cultivation world.

It will only open every three years, and it will only last for three months. You can't get in when you come over the other time. Moreover, this barrier is natural, and even a god-transforming monk cannot break through.

After knowing this information, Lin felt much more relieved. At least even if the Bai family thought that they might run to the mortal world, it would not be so easy to get in.

A few days later, the barrier of isolation in the mortal world opened, Xiaomei and Zhou Hui followed the large army into the mortal world, and Lin gave them most of the top-grade spirit stones on their bodies.

In the past few days, she has refined the blank array plate and array flag she bought before into a defensive mystery array, so that they can use the formation to protect themselves when they encounter danger. In the mortal world, those top-grade spirit stones can protect them for a long time.

After seeing off Zhou Hui and Xiaomei, Lin began to plan for the future. She did not forget that she almost became a family girl branch. She would not let it go, whether it was the Bai family or the abnormal development of cultivation world.

However, Lin also knows that fighting alone is not good. She needs help, and the best helpers are those of her kind.
