After visiting more than a dozen stalls specializing in jade slips in a row, Lin Feng found nothing. But at a small and inconspicuous grocery stall, Lin Feng was attracted by one of the items. There were quite a few items on the grocery stall, but they were all small and disorderly, but Lin Feng still saw the item at a glance.

It was a bamboo slip, and the top was worn out. The reason why Lin Feng saw it at a glance was because it was the largest item in the grocery stall, more than a foot long and about two inches wide, and it looked like a wooden board from a distance.

Lin Feng was curious to pick up this piece of bamboo slip, but the stall owner reached out in time to stop him. Lin Feng looked at the stall owner suspiciously: "Isn't this piece of bamboo slip sold?"

The stall owner looked like a very shrewd thin old man, he glanced at Lin Feng and said, "Since it is put out, of course it is going to be sold!" However, the bamboo slip is not as wearable as the jade slip, it is very wear-resistant, and it will be damaged if you are not careful, if you sincerely want to buy it, let's talk about the price first." ”

Lin Feng had no choice but to stretch out his hand back, and secretly said that this old man was too stingy, thinking that Lin Feng was the kind of master who only looked at it and didn't buy it, because once the bamboo slip was in Lin Feng's hands, he could remember a little bit, and if he really didn't give money, there was no way for the stall owner.

Lin Feng smiled and said, "Others generally use jade slips to record things, but if you use bamboo slips to record, isn't it easy to damage?"

The stall owner said: "Hehe, there are some things that are difficult to describe accurately in jade slips, so bamboo slips are used!"

Lin Feng was stunned for a moment: "Things that can't be expressed in jade slips can be done with bamboo slips? [~]”

The stall owner smiled: "You are still young, and your knowledge of the cultivation realm needs to be improved, so I will tell you today, some things must be recorded in bamboo slips, and jade slips cannot be used." ”

Lin Feng simply sat down: "Listen up." ”

The stall owner continued: "Most things can indeed be recorded in jade slips, but only one thing is not possible. This thing is Spiritual Breath!"

Lin Feng was even more dazed: "Spiritual Breath, what does this mean?"

The stall owner shook his head: "It seems that you need to learn a lot, and you don't even know the spiritual breath." Spiritual breath is the unique breath of a certain material itself, which is the fundamental sign that distinguishes it from other materials!

All that can be recorded is static words, or moving images, and even sounds and colors can be displayed, but there is nothing that can be done about spiritual breath. []”

Lin Feng: "I kind of understand what you say, but it doesn't seem to be useful to record the spiritual breath?

The stall owner lowered his head and smiled: "What if there are some materials that you have never seen before?" Especially like some spirit grasses, or the essence blood, skin and bones on the body of demon beasts, the color or form may change at different growth stages and storage environments.

There are thousands of materials in the cultivation realm, and if the form or color changes slightly, it may be confused with other materials, but the spiritual breath within it cannot be changed forever!"

Lin Feng suddenly realized at this time: "It makes sense! Then using bamboo slips, you can record the spiritual breath that cannot be recorded in jade slips? But what if the cultivation realm weishenme doesn't use bamboo slips to record things? All the things you use are jade slips?"

The stall owner still said patiently: "Not all bamboo slips can record spiritual breath, only the Bailing bamboo that grows on the side of the spiritual spring has this effect."

Lingquan is generally underground, it is quite difficult to find, but there are many lark bamboos, no one knows which lark bamboo is hidden near the spiritual spring, plus the lark bamboo itself grows very slowly, it must be hundreds of years to make bamboo slips,

And only the roots that are more than a foot long can be used, and the rest of the parts can only be scrapped, because Bailing bamboo has no other great use except for making bamboo slips, so bamboo slips cannot be as popular in the cultivation world as jade slips, but the capacity of bamboo slips is much larger than that of jade slips. ”

Lin Feng nodded: "Oh, then what is recorded in this bamboo slip of yours?"

The stall owner came to the spirit: "Hehe, what is recorded here is simply all-inclusive! There is not only the relevant common knowledge of various ordinary materials, but also the characteristics and functions of a large number of remote and rare spirit grasses, spirit mines, demon beasts and other materials, monks like you who lack knowledge of cultivation materials, with this bamboo slip in hand, it will be much more convenient in the future!"

Lin Feng was overjoyed in his heart, and secretly thought that he was not looking for such a jade slip, and now that it was in front of him, of course he couldn't easily miss it. So he immediately asked, "How are you going to sell it?"

The stall owner's interest was even greater: "I won't hide it from you, bamboo slips are generally rare in the cultivation world, not that it is rare or precious, but most monks think that it is not as durable as jade slips, and ordinary cultivation materials,

It is basically recognizable from the appearance and color, and most of them are no longer necessary to identify the spiritual breath. However, this bamboo slip of mine, it records a lot of materials, and some of them may not even be recognized by the great monks of the Yuan Infant Period.

Therefore, since a long time ago, I have sold this bamboo slip at the price of 300 spirit stones in many markets and fairs, but none of the monks are willing to buy it. ”

Lin Feng was also a little surprised: "300 spirit stones, this is too expensive, right? Some mid-to-high-grade auxiliary exercises are only sold for 200 spirit stones at most, and your bamboo slips are only some material introductions, no wonder no one will buy them." ”

The stall owner looked stubborn: "Good things are always known, and this jade slip of mine is said to have been obtained by a certain master of the Yuan Infant Stage from an ancient ruin." It is likely that a certain great monk in ancient times recorded it in his spare time, because there are some travel notes in it, as well as the ancient monk's personal experience. ”

It's not that Lin Feng can't take out these 300 spirit stones, but his body has swallowed the property of several monks, whether it is Yu Tao or the four great lewd beasts, their net worth is very rich.

Moreover, there were also storage bags for several low-level monks such as Sun Liang, which were also taken by Lin Feng as his own. It is not an exaggeration to say that Lin Feng's current wealth and goods are also relatively rich in the pile of monks in the foundation building period!

However, spending 300 spirit stones to buy a bamboo slip to introduce materials is indeed a bit too expensive. This was in the previous Lin family, and Lin Feng didn't even dare to think about it. The Lin family is short of spirit stones, and the number of spirit stones distributed by the disciples in the family is only a few pieces every year!
