It didn't take long for this capable shopkeeper to send seven or eight colorful jade slips to Sun Yunhao, and asked a graceful woman to pour a cup of fragrant tea for Sun Yunhao.

Sun Yunhao didn't drink it either, but just put a jade slip in the center of his eyebrows, and then slowly probed his divine thoughts, and after a while, he put the jade slip back in its place, took out one again, and concocted it in the same way.

After a short while, Sun Yunhao finished reading all these jade slips. "I want to make a copy of these two jade slips, I don't know how many spirit stones will cost?" Sun Yunhao took out the two jade slips and asked.

"These two books add up, a total of one hundred and seventy spirit stones." The monk said immediately.

"So expensive!" Sun Yunhao was dumbfounded, his face full of incredulity. Although these things were very useful to him, he never expected that these things would cost so many spirit stones.

"Don't mind this fellow Daoist," the shopkeeper saw that Sun Yunhao's face was a little ugly, and hurriedly explained, "You must know that the details and refining techniques in this are the top secrets of every refiner, and our shop has also spent a lot of money in order to get these classics." Although these two books are only elementary and intermediate alchemy, they are extremely detailed, and they are definitely a must-have for alchemy. ”

"I want two at a time, can it be cheaper!" Sun Yunhao said a little unpleasantly.

"This, okay, one hundred and sixty-five spirit stones, below this price, you really can't be the master in the future."

Sun Yunhao nodded and took out two medium-grade spirit stones.

The shopkeeper took the spirit stone, skillfully took out two empty jade slips from the storage bag, put the one Sun Yunhao chose on the empty jade slips, and used a strange handprint to rub the contents of them. Then, he handed the jade slip in his hand to Sun Yunhao, and at the same time took out dozens of lower-grade spirit stones.

Sun Yunhao checked it with his divine thoughts, and after making sure that there was no problem, he flipped it over with one hand, and a piece of white light flew out, putting everything into the storage bag.

Sun Yunhao originally planned to read a few more books in the store, but when he thought that he had just spent so many spirit stones, he didn't say anything more and walked out of this jade building directly.

Sun Yunhao was going to go to some pill shops first to see if he could find the elixir that would be useful to him.

But before Sun Yunhao could walk far, an exclamation came from his ears.

"Medium-grade spirit weapon! Just put a medium-grade spirit stone into it to maximize this effect. ”

"Isn't this an obvious thing, how could I possibly get a medium-grade spirit stone. If I could afford to use a medium-grade spirit stone, I wouldn't have asked for that broken shield. You can buy a superb magic weapon here! ”

"It's you who doesn't understand! Can you, a disciple in the Qi refining period, be able to use a supreme magic weapon? Can you fully unleash the power of the ultimate magic weapon? Spiritual weapons are scarce, do you understand? ”

"Fart! This is a magic weapon that can be used as you like! Your spirit weapon draws energy from spirit stones, a medium-grade spirit stone is worth a lot of money, it won't take long for you to run out of energy, and you have to buy another one! The so-called spiritual weapon is actually worthless! Your broken shield, although it is filled with a medium spirit stone, is just like a monk in the foundation building period, and it will consume hundreds of spirit stones at a time, who will use your broken shield! ”

"That is, this thing is too expensive for the Qi Refining Period, and for Zhuji, this thing is not good for them, it is just a waste of spirit stones."

"Just because you don't know how to use it doesn't mean that others don't! Eight hundred spirit stones, I don't bargain, if you don't want it, you don't want it, don't affect my business! ”

"Eight hundred, are you a fool for me? You can buy a high-grade magic weapon, and you can even buy a low-grade magic weapon! You're robbing! ”

"What are you talking about? Whatever you want, you're a poor ghost anyway! ”

When Sun Yunhao heard that it was a "medium-grade spiritual weapon", he immediately became interested and joined the crowd.

You know, this is a special magic weapon comparable to a monk in the foundation building period! He suddenly thought of the description of the spiritual weapon in an ancient book he had read.

In fact, in a sense, this spiritual artifact is also a kind of treasure. This spiritual artifact is different from ordinary treasures, it is not activated by absorbing the spiritual power of the monk himself, but can be activated by itself. And if the monk wants to urge these artifacts, he only needs to inject a little spiritual power. This spiritual weapon, with the spirit stone as the core, can exert the greatest power.

This is a very ancient method that has been handed down since ancient times, and for various reasons, it is rarely seen anymore and is only recorded in some ancient books.

On each magic weapon, there is a groove in which you can put the spirit stone into it, extract the spiritual power in the spirit stone, and let the magic weapon exert its due power. And every time it is urged, the aura in the spirit stone will be consumed, and once the aura in the spirit stone is exhausted, it needs to be reloaded with the spirit stone in order to be urged again.

And this spiritual weapon, not all spirit stones can be urged. Because of the different materials, only spirit stones of the same attribute can refine a spirit weapon.

As soon as the two of them met, they talked about the spirit stone, it seemed that this spirit weapon itself needed a medium-grade spirit stone to drive, and if it was used to urge it, it would not have any effect at all.

You must know that the grade of this spirit weapon is not only the attribute of the spirit stone itself, but also its own grade.

According to this standard, spiritual weapons can be divided into three levels, namely low-grade spiritual weapons, medium-grade spiritual weapons, and high-grade spiritual weapons.

The low-grade spirit weapon can only be driven by the low-grade spirit stone, while the medium-grade spirit weapon can only be driven by the medium-grade spirit stone. The so-called high-grade spirit weapon is naturally driven by a high-grade spirit stone.

The lower-grade spiritual weapon probably has the power of the Qi refining period, and the medium-grade spiritual weapon probably has the power of a blow in the early stage of foundation building, as for the high-grade spiritual weapon, as long as the high-grade spirit stone is inlaid in it, it can burst out with a terrifying power comparable to the later stage of the Jiedan.

Under normal circumstances, because of the spiritual weapon material, a lower-grade spiritual weapon cannot be inlaid with a higher-grade spiritual stone. If a medium-grade spirit stone is forced into a low-grade spirit weapon, not only does it need to consume a lot of spiritual power, but the effect it can achieve will not be much better than using a low-grade spirit weapon, and it will even cause damage to the low-grade spirit weapon itself because there are too many spirit stones, so that it will be completely discarded after being used several times.

However, when used in conjunction with a low-grade spirit stone and a medium-grade spirit weapon, it can only exert one-tenth of one-twelfth of its power.

It is also said in the classics that although this spiritual weapon is powerful, the demand for spiritual stones is not small. Every time a spirit weapon is activated, one or several low-level spirit stones need to be consumed before a Qi Refining Stage cultivator can activate it. If you want to exert the power of these spirit weapons in the foundation building period, you naturally need to use middle-grade spirit stones. This is not something that ordinary monks can afford.

It was precisely because of these restrictions that the spiritual weapons had almost disappeared in the immortal cultivation world.

However, Sun Yunhao would not think so, for others, the spirit stone may be very valuable, but for him, it is endless. If you can have a medium-grade spiritual weapon, your life-saving ability will be even stronger!

"Although there are not many medium-grade spirit stones, the lower-grade spirit stones can be exchanged for some. When I have time in the future, I will use Xiaoding to upgrade it. Sun Yunhao thought to himself in his heart, "However, eight hundred spirit stones is really a lot of money for a monk in the Qi refining period, if you take out eight hundred in one go, I am afraid that it will arouse the covetousness of many people, and then it will be a big loss." ”

Just when Sun Yunhao was thinking about whether to intervene in this matter, a somewhat familiar cold snort suddenly sounded in his ears:

"Medium-grade spiritual weapons? The person who came was the monk surnamed Leng named "Zombie Face" that Sun Yunhao met when he first entered the cave, and his cultivation had reached the foundation building period. I don't know when, he has appeared behind Sun Yunhao.

The people around him, all of whom were disciples of the Qi Refining Period, heard this master's order and got out of the way one after another.

Seeing this, Sun Yunhao hurriedly got out of the way. Now that he is being targeted by a monk in the foundation building period, Sun Yunhao will naturally not bid again.

The stall owner was a young man with a beard on his face, and when he heard this, he hurriedly picked up the crystal shield in his hand and said, "Master Leng, look. ”

At this time, the monk surnamed Leng had already arrived a few feet away from Xiao Dun, but as soon as he raised his hand, Xiao Dun flew to his hand on its own as if he had eyes.

Sun Yunhao watched this "Master Leng" staring at the small shield for a long time, and suddenly flipped it with one hand, and a crystal clear spar appeared in his hand, and several wisps of white cold air faintly emerged from it.

"Medium-grade spirit stones!" Someone in the crowd whispered.

And this monk surnamed Leng inserted an ice-based spirit stone in the center of the diamond-shaped shield, and suddenly "buzzed", emitting a layer of faint light, making Sun Yunhao and the others feel a cool air coming out of their bodies.

"Huh! It's just a defective product, see for yourself! The monk surnamed Leng glanced at the diamond-shaped shield, and then tapped the upper right corner of the shield with his finger, and asked the seller with some dissatisfaction.

Everyone looked in the direction that Yun Ruoyan was pointing, and sure enough, there was no aura in that corner, nor any light.

Defensive magic weapons are perfect and cannot have any flaws. Once there is an obvious flaw, then it will be used by the enemy, and then continue to attack, which is equivalent to putting yourself in a very dangerous situation.

"Oh, Uncle Mingjian, the younger generation doesn't know that this treasure is flawed." The bearded man was startled and hurriedly explained.
