A mortal’s journey to becoming an immortal begins by becoming the food for monsters and beasts.

And Fu Sheng also learned a lot of things about the immortal cultivation world from the conversation, for example, although the extreme west land can be regarded as a small land compared to the entire human world, but even so, the extreme west still has more than a dozen countries and dozens of immortal cultivation sects!

Each sect has the support of the primordial old monster as the Supreme Elder, and this is also the biggest support for them to become the largest sect in the extreme west.

As for the rest of the small sects, there are countless of them, and even the sect masters of many sects are only cultivating in the foundation building period.

And the land of the extreme west is surrounded by the sea on three sides, and there are many islands on the sea, so there are many sects that put their sects on overseas islands, and in the eyes of mortals, they also have a bit of immortal energy.

And the only passage connecting the extreme west to the mainland is called the Spirit Snake Corridor, although it is called a corridor, but it is just this slender appearance and the same as the spirit snake!

It's just that this spiritual snake corridor is extremely long, and the winding appearance is almost the same as a spiritual snake, so it is called the spiritual snake corridor, and this spiritual snake corridor connects the extreme west and the continent.

Of course, one of the most critical pieces of information Fu Sheng got was about the storage bag.

Speaking of this storage bag, it is also magical, it looks like a leather bag the size of a palm, but there is a huge space of dozens or even hundreds of cubic meters inside.

According to Chen Xingwen, there was no such thing as a storage bag in ancient times.

At that time, those with spatial attributes were all famous Sumeru treasures, which were first-class treasures that only real people in the upper realm could get.

But later, a supreme genius formation master studied the spatial principle on the teleportation array Xi, and he really gradually figured out a magic circle carved in his pocket, which can form a relatively stable different space as long as there is a supply of spirit stones, and link the real world with the mouth of the bag as a node.

It is very convenient to access things with only the guidance of the divine sense.

It's just that the consumption of this storage bag for spirit stones is also not small, and for the storage bag in Fu Sheng's hand, a brand new spirit stone can only last this storage bag for about a month.

Once the time has passed and the spirit stones have not been replaced, the formation cannot maintain a stable space, and the contents of the storage bag will be sprayed out of the mouth of the storage bag in one go.

But even so, this storage bag is a rarity.

Even a monk in the foundation building period may not be able to do one per person, and one spirit stone per month is naturally an astronomical amount for a monk in the qi refining period, after all, many disciples in the qi refining period of many sects can only save a dozen spirit stones in a year.

But for the predecessors of the foundation building period, a spirit stone a month is actually not so painful.

And Fu Sheng has the legacy left by Qing Fuzi, not to mention the treasure material jade books, there are tens of thousands of spirit stones alone, and there are even more than a dozen intermediate spirit stones.

You must know that although the conversion ratio between the intermediate spirit stone and the primary spirit stone is one hundred to one on the surface, in fact, if you really use the primary spirit stone to replace the intermediate spirit stone, even if you come out to one hundred or fourteen, no one may replace it with you.

After all, the stimulation of many formations requires intermediate spirit stones, and the powerful formation primary spirit stones cannot be activated at all.

What's more, whether it is used for the recovery of spiritual power or for cultivation, the intermediate spirit stone is more than one grade higher than the primary spirit stone, naturally no one really thinks that a hundred primary spirit stones can replace an intermediate spirit stone of similar quality!

Besides, if you don't put so many things into the storage bag, Fu Sheng can't buy dozens of carriages to pull all these things on

, it will be too eye-catching! And the storage bag can naturally hold a living person, but if it is used to fight against the enemy, it will be too useless! In reality, no one will do this!

Not to mention the rarity of the storage bag, even the foundation building monk can hardly hold more than two, most of them are used to hold those important or large treasure materials on the body, where can you prepare a separate

storage bag to trap the enemy? Not to mention that if you put the enemy in the storage bag, you can't trap the enemy for long at all.

After all, there are too many ways for the enemy to get out of trouble, whether it is to take away the spirit stones that provide spiritual power to the storage bag, or to destroy the surrounding formations, the storage bag can be invalidated instantly, so that you can easily get out!

As for whether the storage bag can be refilled with storage bags, the answer is naturally no!

The reason is also very simple, the principle of storage bags is not to open up a completely new space. After all, that kind of unbelievable ability is not something that a mere human realm cultivator can do, and the principle of the storage bag is actually similar to that of the teleportation array.

The principle of the teleportation array is to associate the two formations in two places through the formation, and then stretch the space and connect the space stretched by the two formations together, so as to form a relatively stable spatial teleportation channel.

The principle of the storage bag is similar, except that the storage bag is not the kind of fleeting space stretching like a teleportation array, but uses the aura in the spirit stone to build a relatively stable space.

There is no other formation that forms the same pulling force and connects with it to form a channel, and in this relatively stable space, storage can be carried out!

According to Fu Sheng's understanding, it is like blowing bubbles, after the soapy water that was originally a plane is blown up, a large space is naturally formed inside.

And if you use the bubble to catch the bubble, as long as you puncture the membrane inside the circle, the bubble will naturally expel all the air inside the body, and restore it to a flat appearance!

Under such mutual influence, the result is that either both bubbles are completely shattered, or both bubbles lose their effect, and all the things inside the space are spit out.

As for the higher-level spirit beast bag, it is a rarer thing than the storage bag!

Because after this spirit beast bag is packed into the spirit beast, it can not affect the normal flow of spiritual energy, even if the spirit beast is in the spirit beast bag, it can also absorb the spiritual energy of heaven and earth and cultivate on its own.

And because the spirit beast bag is engraved with a spirit gathering array, the spirit beast bag can absorb the spiritual energy between heaven and earth on its own, unless this spirit beast bag is in some special places without spiritual energy, it does not need additional spirit stones to maintain the formation.

And many huge spirit beasts are not convenient to carry

, the spirit beast bag is naturally the best choice! It's just that because the production process of the spirit beast bag is several times more complicated than the storage bag, and the materials used are even more cherished, so the number of spirit beast bags is far less than that of the storage bag!

If you see several spirit beast bags hanging around someone's waist in the immortal cultivation world, then this kind of person had better not be easily provoked.

Because of the high cost of the spirit beast bag, all the spirit beasts that were put into the spirit beast bag and subdued were all rare and abnormal rare beasts!

Either they were extremely powerful, or they had extremely special functions. Otherwise, how could a low-level spirit beast make people spend a lot of money to buy

a spirit beast bag for storage? And since the spirit beast bag does not need spirit stones to maintain the magic circle, there are also many wealthy people who use the spirit beast bag as a storage bag.

It's not that these people will feel sorry for this mere piece of spirit stone per month, because the price of spirit beast bags is often several times or even dozens of times the price of storage bags.

These people are often disgusted that it is too troublesome to need to replace the spirit stones every month, and it is common for immortal cultivators to retreat for a few years or even more than ten years. You can't just clean up those scattered things first thing when you come out of retreat, plus you have a lot of money, so you naturally choose a more convenient spirit beast bag!

As for the smaller storage treasure, it's not that no one wants to do it, but now the palm-sized storage bag is already the limit that can engrave the complete formation.

Everyone knows that if you make a storage ring, things like storage bracelets will definitely be more hidden and more convenient to use. However, the engraving of the formation also requires space, and if there is not enough space to engrave the formation, it will naturally not be able to produce an effective and stable

storage space! Moreover, after countless years of efforts by the formation mage, it was found that the storage bag made of the magic circle engraved on the skin of some spirit beasts not only has more space, but also has a higher stability of space, so the production method of the storage bag has been continued.

However, it's not that there are no other forms of storage magic weapons in the immortal cultivation world, it's just that those are too rare to be regarded as the norm.

When Fu Sheng learned the information about the storage bag from Chen Xingwen's mouth, he felt even more glad in his heart for his caution.

Fu Sheng hid the storage bag in his sleeve as if it was an unintentional act to keep his money out, but it was also this act that avoided becoming a target for the attention of other monks.

After all, this storage bag can be regarded as a rare thing, even a monk in the foundation building period can't do it for everyone, why do you Fu Sheng a monk who is only a monk in the fourth layer of the Qi refining period have a storage bag?

At that time, there will definitely be many more twists and turns out of thin air, which is naturally what Fu Sheng does not want to see.

Back to the room, the room is quite elegantly furnished, although the room is not very large, but it is also divided into two rooms.

The carved bed is covered with silk bedding, and there are many calligraphy and paintings on the surrounding walls. Of course, you don't need to think about it to understand that these calligraphy and paintings themselves have no value and are not antiques, after all, they are rented to guests

, lying on the bed, Fu Sheng, who has been struggling to survive in the Tianheng Mountains for four years, also feels extremely tired, and only feels sleepy.

However, Fu Sheng still fought his spirit, and used thin silk threads and bells to defend the entrances and exits such as doors and windows. Although it is impossible to avoid the invasion of thieves, it can always play a role as a warning when thieves invade!

In this way, Fu Sheng lay on the bed with a little peace of mind, thinking about whether his performance this day was anything pleasant or too sharp, and he fell into a deep dream.

And Fu Sheng's sleep was three days and three nights.
