As for the use of spirits by themselves, in addition to making magic weapons and cultivating summoned beasts, spirits can also be used to strengthen the stars, so that mages can obtain more advanced magic.

For example, a low-level mage can use first-level magic, second-level magic, and third-level magic, and then there is none. But once the spirit has strengthened all of the mage's stars, the mage can use level 4 or even level 5 magic.

Among them, if you want to strengthen the seven stars from level 3 to level 4, you need seven slave-level spirits, and from level 4 to level 5, you need seven general-level spirits, and then if you want to strengthen them, you need to have a commander-level spirit.

However, the spirit is very precious, a slave-level spirit is calculated at five million, then seven spirits need thirty-five million, which is enough to buy two inferior fire-type thunder-type spirit seeds or ordinary wind-type water-type earth spirit seeds. And that's just the first level of fourth-level magic.

If you look at the power of magic, the power of beginner level 4 magic is only about a quarter of that of intermediate level 1 magic. The original protagonist has the primary fourth-level magic blessed by the spirit seed, which is only half of the power of the intermediate first-level magic without the blessing of the spirit seed.

Therefore, few people are willing to spend a lot of money to buy spirits to strengthen their own stars.

Yang Yao is not very willing, but if the cost performance is high in the future, Yang Yao does not mind being extravagant, after all, no one will dislike his strength.

In addition, the spirit can also be used to cultivate summoned beasts, but the problem is that Yang Yao doesn't have summoned beasts now.

However, since the spirit can strengthen the star, then the mage should be able to use the spirit to assist himself in breaking through the realm. However, Yang Yao still gave up this idea, and Yang Yao didn't want to use himself as a guinea pig yet.

As for why he didn't sell this general-level spirit in Bocheng, it wasn't that Yang Yao didn't want to. The question is, how many people in this Bo city can afford it?

The inheritance of Yang Yao's deceased parents is only 10 million, and Yang Yan and his wife don't have a lot of money, and they can't even afford a spirit seed.

Other mages may not be as good as Yang Yan and his wife, and the only ones who can afford to buy a general-level spirit may be the Mu family, the Magic Association, the Hunter Alliance, or the Snow Peak Mountain Army.

But Yang Yao can't guarantee that he won't reveal his identity when he sells spirits. After all, in the small place of Bo City, the appearance of a general-level spirit may be more eye-catching than the sudden death of Yu Ang of the Mu family when he was cultivating. Just kidding, of course, it was impossible for Yu Ang to die suddenly while cultivating.

The dark yellow balloon? Yang Yao took out a drop and put it in the palm of his hand and looked at it, and suddenly Yang Yao felt that his magic energy had grown a little bit by itself because of this drop of liquid, but the growth of this trace of magic energy was a little irritable.

Is this the Wild Spring? Yang Yao remembered that the Wild Spring Water was refined from the Wild Poppy, and the Wild Poppy seemed to come from the American Ojos Holy Academy, and Yang Yao didn't remember the specific content very clearly, after all, Yang Yao had been traveling for fifteen years.

However, Yang Yao remembered that there seemed to be a very important person in the Ojos Holy Academy, and that person was Gabriel, the archangel of the Holy City. But Yang Yao didn't remember who that person was.

This Wild Spring Water, also known as the Furious Spring, can boost the strength of cultivators and creatures in a short period of time. However, this water is more like a stimulant, and the wild spring water will frantically suck the nutrients and energy in the body of living beings, and at the cost of making living beings become very crazy and irrational.

Black Sharon generally likes to melt this kind of thing into the rain to attract demons, but the wild spring water in his hand is certainly not the product of dilution.

Thinking of this, Yang Yao hurriedly put away the Wild Spring Water in his hand, although the Wild Spring Water will not have any effect on himself in a short period of time, but this thing should not be used lightly.

As for the rest of the blood, it should be the blood of the blood-streaked troll rat or refining blood, it can also be called bloodline, this kind of thing can be used to cultivate summoned beasts, which can speed up the growth rate of summoned beasts, and can also increase the success rate of summoned beasts.

However, now Yang Yao doesn't have any summoned beasts, so keep this group of alien blood, and sell it when he has a chance in the future.

A bottle of general-level demon bloodline can probably be sold for more than 10 million (Chapter 267 of the original book), and the bloodline of this group of blood-patterned troll rats is of a low grade, but it should be possible to sell it for about 80,000 or 90,000.

It's a pity that the blood-streaked troll rat didn't burst out with any alien bones or skins, otherwise Yang Yao would have been able to try to refine some simple magic weapons by himself.

It is not difficult to refine low-level magic weapons, and the refining methods of magic weapons have been taught in elementary and junior high school, and some have also been taught in this semester of high school.

If the disciplines of this world are the same as those of the previous life, biology should probably be demonology, physics and chemistry should correspond to magic science and materials science, history should correspond to the evolution of magic, foreign languages should correspond to demon linguistics, and other disciplines also have corresponding subjects.

There are two requirements for refining magic weapons, one is to have materials, and the other is that the mage has a thunder or fire type, because only these two systems can refine magic weapons. Of course, some special magic weapons, such as mages who refine undead vessels, need the undead system.

The difficulty of refining low-level magic weapons is not very high, so some fire mages or lightning mages can refine some low-level magic weapons by themselves to sell. A large part of the magic weapons in the shops that sell magic weapons in Bo City are made by this group of mages.

There are also some mages on Xuefeng Mountain who set up stalls to sell their own magic weapons, but these magic weapons are even more low-level, and even the shops that sell magic weapons don't buy these things, and each piece is only tens of thousands to hundreds of thousands.

This kind of magic weapon is similar to some people in the previous life who used electronic parts to assemble an electric lamp, or made some unsightly weapons out of some metal. Although these magic weapons can be used, their power is generally very poor, and they may not be as good as the magic of beginner level 1 and 2 mages.

However, from the beginning of the magic weapons suitable for the use of intermediate mages, they are precious, and almost all the magic weapons suitable for the use of intermediate mages are less than ten million.

According to the grade, magic weapons can be divided into four levels: mortal level, spirit level, soul level, and heaven level, which correspond to the four major realms of the mage: beginner, intermediate, high, and super.

Generally, the magic weapons used by mages are all magic weapons of the same level or lower level. As for the more advanced magic weapons, it is not impossible to use them, but it is difficult for ordinary mages to obtain magic weapons that do not belong to their own level.

For example, beginner mages use mortal-level magic weapons at most or no magic weapons, for example, the magic weapons used by the outstanding students of Tianlan Magic High School are ordinary stardust magic weapons. And Mu Ningxue seemed to be using a spirit-level nebula magic weapon when she was at the beginning level.

As for Yang Yao, the Soul Gathering Demon Ring used by Yang Yao belonged to a heaven-level magic weapon. In its heyday, the Golden Phoenix Xuanniao Jade Pendant should have been a forbidden spell-level magic weapon, but the current Golden Phoenix Xuanniao Jade Pendant should belong to a heaven-level magic weapon.
