Lei Luo wandered around this open square for about half an hour, during which time he had seen many monks trading many items, and he had a general idea of the value of these items.

He found that most of these monks had some materials on their stalls, and the value of them was clearly marked, and the currency was a material called a 'spirit stone'.

According to Huang Zhenren's material illustrated book, spirit stones are a kind of basic currency in the immortal cultivation world, if an item is worth five spirit stones, then it means that five lower-grade spirit stones can buy this item.

For monks, the spirit stone is a material that can directly extract spiritual energy for cultivation, and it is an indispensable material for any monk.

The cultivation of a monk is nothing more than absorbing and extracting the spiritual energy in heaven and earth, gathering and converging these spiritual qi in his own body to mention his own cultivation.

However, because of their qualifications, the vast majority of monks meditate and absorb spiritual energy very slowly, unless you are a genius of the heavens, or some kind of special physique, these can speed up this speed.

The spirit stone is different, a low-grade spirit stone for the monk to absorb, it may take a little time to be absorbed, but the amount of these spiritual qi is the same as the time spent by the monk meditating, which can save a lot of time in cultivation.

Spirit stone, to put it bluntly, is just a special crystalline formed by the aura condensed somewhere, but this crystalline is indeed an indispensable thing for many monks.

And above the lower-grade spirit stones, there are medium-grade spirit stones and high-grade spirit stones, I heard that there are some top-grade spirit stones in the legend, but this kind of ethereal thing, he has no concept now.

The value of a high-grade spirit stone is theoretically equal to one hundred medium-grade spirit stones, and it is also equal to ten thousand lower-grade spirit stones, but in fact, a high-grade spirit stone often has to be exchanged for more than 10,000 or even 20,000 lower-grade spirit stones to have a market.

After all, the spiritual energy reserves in the high-grade spirit stones are incomparable to 10,000 lower-grade spirit stones, and this is a truly priceless and marketable thing.

And this time, the most valuable item is a low-grade magic weapon, which is a red feather fan that is said to be refined with fire-attribute materials, and the effect of this magic weapon is that it can increase the power of fire-attribute monks when using spells, and at the same time reduce the time for invoking spiritual power in the body, and improve the efficiency of spellcasting.

The value of this low-grade magic weapon is twenty spirit stones, and it is said that there are many people who take a fancy to it, but they have been bargaining, and Lei Luo also saw that many people have bid fifteen or eighteen spirit stones.

Since he himself is not the kind of person who likes to cast spells against enemies, he did not participate in this bidding, not to mention that he is now penniless, so he is looking around for some bartering stalls.

"Water attribute materials, in exchange for one or two spirit copper ore!"

"One or two fine iron, in exchange for wood attribute materials, some come and take a look!"

"The defective magic weapon refined by the refiner is said to be comparable to the attack power of the lower grade magic weapon, don't miss it when you pass by!"

Lei Luo listened to the shouting around him all the way, and was slightly speechless, it seems that no matter which place in the world, there are some people who like to tout indiscriminately and shoddy.

At the vendor of the defective magic weapon he was passing by just now, the long knife with a pattern he was selling, Lei Luo took a closer look and found that there were some small cracks on the surface of the knife, which were covered up by the vendor with a pattern to confuse him.

If whoever buys it at that time will fight with someone in the future, and someone will come over with a knife, and your weapons will be broken, then the consequences can be imagined, but in this case, it is impossible for the buyer to go to the buyer to theorize, because the fate has been explained.

However, he doesn't like to meddle in his own affairs, as long as he doesn't suffer a loss, he can turn a blind eye to him, so after taking a walk, he still continues to wander around the square.

Finally, after a long day of careful searching, he found what he was looking for on a street vendor.

I saw Lei Luo pretending to walk by the vendor casually, then glanced sideways a few times, and finally narrowed his eyes, and the whole person squatted down and carefully inspected the vendor.

I saw that next to the vendor owner, he wrote down his trading scope and requirements with a wooden plaque: the stall owner only trades in immortal cultivation spells, fireball techniques, wind blade techniques, earth wall techniques, water bomb techniques, wood winding techniques, etc.

The scarce basic method of Qi training stage "Treasure Appreciation Technique" is exchanged for a copy of the exercise method from the Qi training period to the eighth layer, and if it is a complete exercise of the tenth layer, a copy of "Controlling Matter" is attached.

"What's so wonderful about this treasure appreciation technique?" asked Lei Luo as he crouched down and turned to the vendor.

The vendor also noticed Lei Luo, and when he heard the kid in front of him ask about this 'treasure appreciation technique', he knew that there might be a play, so he politely explained it to Lei Luo.

It turns out that after the monk gets the magic weapon, he needs to practice it, if it is a magic weapon refined by himself, then he naturally knows the attributes, but if it is a magic weapon obtained from other places, if he doesn't know anything, he needs to be identified by a professional.

A magic weapon that doesn't know anything, if you don't have an identification technique, you can't know the power and function of this magic weapon, etc., and even if you control it at that time, it is more likely to have problems.

For example, if a monk gets a defensive weapon and is made into a ruler, but if the monk uses the control object to sacrifice it and uses it as an attack weapon against the enemy, then the weapon may not be powerful at all, and he will be hit and killed by the opponent's magic weapon.

Of course, this happens relatively rarely, and some monks may test it after getting it, and if they test it a few more times, they will slowly find out the efficacy of the magic weapon.

However, Lei Luo didn't know these things very well for the time being, and this 'treasure appreciation technique' actually helped the monk save some effort.

"Why do you want to exchange it for the complete exercises of the Qi Cultivation Period?" Lei Luo suddenly asked again, but he had a faint answer in his heart.

At this time, the vendor opened his mouth and explained to Lei Luo that the immortal cultivation exercises he had obtained at the beginning were not complete, and many of the scattered cultivators had no sects and no sects, and the exercises in his hands were only up to the fifth and sixth levels of qi training.

There are even some casual cultivators who are extremely talented, but the exercises are only a few layers in the front, so they may not be able to build a foundation in this life, and even be low-level monks in their lifetime.

There are many, many examples of this, so practicing Qi and complete exercises is actually a very scarce thing, in the eyes of casual cultivation, exercises are the foundation of the monk's life, you can have no magic weapons, no spirit stones, no spiritual materials, but the exercises for cultivation must be there.

"In that case, I don't think your treasure appreciation technique is worth this complete qigong practice even if you add this control technique," Lei Luo had a rough idea in his heart, and began to bargain.

"This, since that's the case, then how about I subsidize you with five more spirit stones!" After the vendor knew that Lei Luo had the complete exercises in his hands, he made the biggest concession.

"Deal!" Lei Luo had the attitude of giving it a try, but he didn't expect the vendor to accept it, so he nodded and agreed to the deal.

He handed over to the vendor the jade slips that recorded the exercises of "Practicing Qi Decision", and took five spirit stones and two jade slips with "Treasure Appreciation Technique" and "Controlling Matter Decision" from him.

After Lei Luo put the things away, he felt that when the spirit stone was in his hand just now, a faint aura emanated from the spirit stone, and the aura used for cultivation was really exactly the same as the aura in these spirit stones.

After getting what he wanted, he didn't have the interest to go shopping, so he looked for Bai Muling's location, and saw that she and Liu Zhen were also wandering around in the square, so he walked towards the two.

"Senior sister, I'm almost done shopping here, so I'll go back first, do you want to go shopping here again?" After walking to the other two, Lei Luo said to Bai Muling.

"Well, I've seen it almost here, I don't have anything else to buy for the time being, so let's go back with you, junior brother!" Bai Muling saw Lei Luo coming over at this time, and he found an excuse to say goodbye to Liu Zhen, and then took Lei Luo back to his residence.

After seeing Bai Muling leave, the young master of the Liu family narrowed his eyes, and the smile disappeared from his face.

After glancing around, his whole face showed a look of disgust, and then he snorted coldly and left the place.
