In addition to the different surnames of the spirit stones inlaid with the spirit tools, the levels are also different.

According to this, the spirit tools can be simply divided into low-grade spirit tools, middle-grade spirit tools and high-grade spirit tools, which correspond to low-level spirit stones, middle-level spirit stones and high-level spirit stones respectively.

Lower-grade spirit tools only need to use low-grade spirit stones to activate and use, while medium-grade spirit tools must have middle-grade spirit stones to exert their full power. Of course, the high-grade spirit tool is inlaid with high-grade spirit stones.

The power of the lower-grade spirit tool is equivalent to the level of the Qi refining period, the middle-grade spirit tool can reach the level of a full attack in the foundation building period, and if the high-grade spirit tool is equipped with a high-grade spirit stone, it can exert the terrifying power of the monks above the knot stage.

Generally speaking, due to the limitations of the material of the spirit tool itself, low-level spirit tools cannot be equipped with high-level spirit stones. If you forcibly inlay a middle-grade spirit stone into a low-grade spirit tool, not only will the spiritual power consumed greatly increase, but the effect of releasing it will be similar to that when inlaying a low-level spirit stone, but because of the use of too high-grade spirit stones, the spirit tool itself will also be damaged, and it will be scrapped after a few uses.

On the contrary, if a low-grade spirit stone is inlaid on a medium-grade spirit tool, only a very small part of the power can be exerted.

It is also mentioned in the ancient books that although the power of the spirit tool is amazing, the consumption of spirit stones is also extremely heavy. It is equivalent to the use of a spirit tool with the full force of a high-level cultivator in the Qi refining period, and it will cost one to several low-level spirit stones. And if you want the power of the spirit equipment to reach the level of a foundation building stage monk, you must use a mid-level spirit stone. This is simply an unbearable consumption for ordinary monks.

It is precisely because of all these restrictions that spiritual tools are almost extinct in the world of cultivating immortals.

But Zhao Di didn't think so, although the spirit stone was precious to others, it was inexhaustible to him. If he could have a medium-grade spiritual tool, wouldn't there be another way to save his life!

"You can't get a middle-grade ice spirit stone, and a low-level ice spirit stone can still be exchanged for a few pieces. When the time comes, you can upgrade it with Xiaoding. Zhao Di thought like this, "But eight hundred zero stones are too many, a disciple in the Qi refining period will definitely attract attention if he takes out so many spirit stones at one time, but the gains outweigh the losses." ”

Just as Zhao Di was thinking about whether to make a move, he suddenly heard a familiar cold voice:

"Medium-grade spirit equipment with the surname Bing? The one who spoke was the "zombie-faced" monk surnamed Leng that Zhao Di had seen in the middle of foundation building when he was at the entrance. I don't know when, he actually came behind Zhao Di.

The onlookers were all Qi refining period cultivators, and suddenly heard a foundation-building stage master uncle behind him speak, and they all hurriedly dodged aside.

Zhao Di also quickly stepped aside. Since there is a monk in the foundation building period who has taken a fancy to it, then he will definitely not dare to buy it.

When he heard this, he immediately held the crystal clear diamond-shaped shield in both hands and said, "Uncle Leng, please take a look." ”

The monk surnamed Leng was still a few feet away from the small shield at this time, but when he grabbed the small shield void with his right hand, the little shield automatically flew into his hand as if it had eyes.

Zhao Di saw that this Uncle Leng looked at Xiao Dun for a long time, and suddenly his palm turned over, and a transparent spar appeared in the palm of his hand, and a few traces of cold white cold air emanated from it.

"Intermediate Ice Spirit Stone!" someone among the onlookers softly shouted out the name of the transparent crystal.

The monk surnamed Leng embedded the ice surname spirit stone into a groove in the middle of the diamond-shaped small shield, and as soon as it was inlaid, the small shield emitted a faint aura with a "buzz", and several monks, including Zhao Di, immediately felt a chill.

"Hmph! it's just a remnant, you see!" the monk surnamed Leng glanced at the diamond-shaped shield a few times, pointed to a place in the upper right corner of the shield, and said to the seller unhappily.

Everyone looked at the part of his finger, and sure enough, this corner seemed to have no spiritual power supply, and no spiritual light was emitted.

The most important thing for defensive magic weapons is integrity, and there can be no dead ends in defense. If there is an obvious loophole, and the opponent seizes the weakness and keeps attacking, it is simply putting yourself in danger and ignoring it.

"Ah, Uncle Mingjian, my nephew didn't know that this was a remnant. The beard was shocked and hurriedly defended.

"Hmph!" The monk surnamed Leng didn't say much, took out the middle-grade ice spirit stone, and then threw the small shield to the bearded man.

"Hehe, a remnant spirit tool is still sold for eight hundred spirit stones, think about spirit stones, go crazy!" The voice that spoke came from a monk who was scolding the bearded man just now.

The beard and beard turned red, but in front of the monk surnamed Leng, he didn't dare to say anything.

Since it was a remnant that was of little use and consumed a lot of money, the monks who were naturally watching also lost interest. Seven or eight people, including the monk surnamed Leng, left the stall and went elsewhere.

Only Zhao Di was left in the same place.

After he waited for everyone to leave, he stopped the frustrated man who was about to close the stall, and said in a low voice: "The remnants of the spirit apparatus can't be sold for eight hundred spirit stones, how many spirit stones are you willing to sell?"

Dahan was stunned for a moment, but he didn't expect that someone would be willing to buy this chicken rib knowing that it was a remnant, and hurriedly replied: "Your Excellency, if you want to buy it, it will only sell for three hundred, no, only sell for two hundred spirit stones." He was ruthless and lowered the price several times.

"Okay. Zhao Di took out two middle-grade spirit stones and handed them to Dahan.

The big man happily put away the spirit stones, handed over the small shield to Zhao Di, and also recovered ten low-level spirit stones. In this Guling Street, the recognized exchange price of a middle-grade spirit stone is still one hundred and five low-grade spirit stones.

Zhao Di quickly put Xiao Dun into the storage bag, and walked to the other stalls without looking back.

Not long after, Zhao Di changed his voice a few more times and visited a few shops and stalls, using an exchange ratio of twenty-five to thirty to one, in exchange for a few low-grade ice spirit stones.

However, the most important purpose of his trip, which was to exchange for some elixirs that would be beneficial to his cultivation, had never been achieved.

After all, the most of the Taixu people are high-level disciples in the Qi refining stage like him, and if there is this kind of elixir for sale, I am afraid that it will be sold out as soon as possible. Even if it is sold at a high price, there is no shortage of some wealthy monks from the Immortal Cultivation Clan, who are willing to spend a lot of spirit stones on pills.

After looking for almost a whole circle, he didn't find a suitable pill, and Zhao Di was a little helpless. Could it be that his cultivation was going to stagnate at the eleventh layer in the past six months? With his spiritual root qualifications, even if he used high-grade spirit stones to meditate and cultivate, it would be difficult for him to advance to the next level in a short period of time.

Zhao Di thought of it depressedly, and at the same time walked into the last shop selling pills on Guling Street.

"An elixir that is beneficial to the cultivation of high-level cultivators in the Qi refining period?" The shopkeeper was a middle-aged young woman who still had charm, she repeated Zhao Di's question, and said, "Hehe, this question is asked by no less than twenty or thirty people at every trade fair. It's a pity that elixirs like the Myelin Cleansing Pill and the Yijin Pill that are very helpful for cultivation are really very rarely circulated. In most cases, it is just after refining and being emptied. We don't have any of these elixirs at the moment. ”

"Don't you have one either? If there is, I'll buy some and try it too. Zhao Di asked again.

"No, no one wants this kind of thing when it is expensive, and if it is sold cheaply, it will not make a few spirit stones, and they are all given away when selling pills. The young woman said regretfully, but after a while, she said, "However, there is an elixir in this shop, which is also effective for high-level cultivators in the Qi refining period. It's called Yangshen Dan. I wonder if you've heard of it?"

"The Divine Cultivation Pill is an elixir that is said to improve the monk's divine sense, but I have heard that the effect of the enhancement is very insignificant, and it is almost useless. Zhao Di thought for a while and replied.

The young woman pursed her lips and smiled, and said, "Hehe, Daoyou, this is a mistake. It is true that the cultivation of the Divine Pill can indeed improve the monk's divine consciousness, but the improvement of the divine consciousness is as obvious and direct as the spiritual power! I can guarantee that as long as a certain amount of the Divine Pill is consumed, the Taoist friends will definitely be able to clearly experience the great changes in the divine consciousness. This Dan has existed for more than a thousand years, if it is in vain, how can it be passed down to this day!"

"Oh, what the shopkeeper said is reasonable, what is the price of this Divine Cultivation Pill?" Zhao Di is still quite interested in this Divine Cultivation Pill, he didn't feel that his divine sense was not enough before, but now after refining the weapon regularly, he found that there are too many places that need to use divine consciousness, and it is inconvenient to do anything if his divine sense is not enough.

"Fifty spirit stones a grain, if you buy more at a time, our store will give another batch of Dan. The young woman quoted a price that Zhao Di felt was acceptable.
