The spirit of the machine is the symbol of the magic weapon.

At the same time, after possessing the machine spirit, the magic weapon can exert its true power.

The most prominent feature is that as long as the master gives orders to the machine spirit, there is no need to even be distracted to control the magic weapon, and the machine spirit can help the master fight together.

Moreover, the strength of the machine spirit will also play a great role in increasing the power of the magic weapon.

The sum of these various effects and benefits is enough to make any cultivator rush to it, after all, as long as the weapon spirit is added to the magic weapon, the improvement of combat effectiveness is really not a little bit.

However, the different levels of machine spirits are still very big for the magic weapon. After the death of a monster of the corresponding level, its level will drop by one level.

In other words, a two-star level demon beast, the soul after death is a one-star soul, a three-star level demon beast, the soul after death is a two-star soul, and so on.

The soul of a one-star level demon beast has almost no effect, because it is too weak, even if it is added to the magic weapon, it will not have the slightest effect at all.

And the fundamental reason why magic weapons are so difficult to refine is that it is too difficult to refine the soul of a demon beast into a magic weapon to become a tool spirit.

The higher the level of the soul, the more difficult it is to refine it into an instrument spirit.

Two-star level machine spirits basically can't communicate with their masters, but they only play a little role in autonomy and domination in the entire magic weapon. This is mainly reflected in some defensive magic weapons, such as some armor-type defensive magic weapons, in which the machine spirit can judge the situation and help their master open the defensive magic circle in time when it is threatened.

This kind of two-star instrument spirit is actually not particularly significant, and most of the magic weapons refined are low-grade magic weapons. Lin Feng's azure sword actually belongs to this type, and the artifact spirit sealed in the azure sword is a two-star artifact spirit.

Therefore, Lin Feng has never used the Azure Sword to have any great achievements, after all, it is very precious to ordinary cultivators, and it is enough to improve many low-grade magic weapons of combat effectiveness, but it is of little significance to Lin Feng, he has more methods and methods, and the power is enough to be above the Azure Sword.

And the refining materials of the Azure Sword are also too ordinary, although they are already the most precious refining materials that can be found among ordinary cultivators. However, this material is at most a medium-grade magic weapon, and there is too little room for improvement.

It can't compare to Lin Feng's Fengtong Sword at all, and in the later refining, Lin Feng has added almost all the precious and suitable materials that can be found.

Fengtong Sword, the main materials are Xuaniron and Mithril, auxiliary divine water, and some Xuanjin, Nine Heavens Meteorite, etc., these are some materials that Lin Feng scavenged from major treasure houses when he was on Earth.

These materials are only a few pieces away, some only have one or two grams, but the degree of preciousness can be imagined. Even in the cultivation realm, it is priceless, almost rare for a thousand years.

It's just a pity that if it is not integrated into the machine spirit, no matter how Lin Feng upgrades the Fengtong sword and how many powerful refining materials are added to it, it is at most a powerful flying sword.

It was precisely for this reason that when Lin Feng found that there were demon beast salamanders in the desert below, he wondered whether to hunt some salamanders, and then look at their souls, screen out some powerful ones, and integrate them into the Fengtong Sword as weapon spirits.

In this way, the power of the Fengtong Sword may have increased more than ten times.

It's just that this process of integrating into the machine spirit is not so easy, even Lin Feng is not 100% sure, so he has to catch more souls of Lin Feng's fire lizards.

Whew!

At the bottom of the desert, another salamander felt Lin Feng's spiritual sense scanning, and immediately became angry, and jumped up from the desert suddenly, wanting to bite Lin Feng off in the air.

But now Lin Feng has killed several powerful salamanders and formed his own routine of fishing salamanders, so he ...... He easily predicted the direction and time of the salamander jumping, and then the Fengtong sword was ready, and he saw that the salamander that had just jumped out was directly cut in two.

One by one!

These three-star level salamanders, although they have condensed Neidan, are still intellectually low, they know how to use brute force to fight with cultivators, and they don't know how to think, at most they are just making some traps under the desert.

Therefore, in just a quarter of an hour, Lin Feng had already quickly killed twelve salamanders, basically all of them were three-star level, and occasionally one or two were two-star level.

As for the four-star level salamander, Lin Feng didn't see it. After all, a four-star level salamander is equivalent to a cultivator in the Yuan Infant Stage.

Every salamander that was killed, their inner pills were put away by Lin Feng, and as for leather armor or something, Lin Feng didn't need it. Hongxia looked like a fart, following behind Lin Feng's ass, waiting to pick up the bargain.

"Lin Daoyou, you don't know. The leather of these salamanders is the best way to make bags, but it is too difficult to kill them and keep them intact. After all, if our cultivator's spell is slightly blasted, the skin of the salamander will be damaged, and if there is no luster, the bag made will not look good. ”

After Hongxia picked up the salamander that Lin Feng had just killed again, she said with a smile, "You are still powerful, after the sword is broken, the leather of these salamanders has been completely preserved, the upper section and the lower section, one salamander can almost make two complete bags." ”

"What? You actually want to use salamander leather to make bags? Isn't it a magic weapon? Salamander leather should also be considered a relatively good material, even if it can't be made into a magic weapon for defense, it can also make some spiritual weapons with good defense?"

Hearing Hongxia say that she wanted to use the leather of the salamander as a bag, Lin Feng couldn't help but sigh, sure enough, the whole world ...... No, in all the universes, in all worlds, women are actually the same, they all love beautiful clothes, precious gold and silver jewelry, and ...... A wide variety of bags.

"With such a beautiful leather, why do you want to take out those useless spiritual weapons and magic weapons? Before, my aunt drew a manual, and the styles of many bags on it are very good-looking, Lin Feng, if you kill more salamanders, I will be able to have enough materials to make all the bags that my aunt drawn. As she spoke, Hongxia pulled Lin Feng's arm and said a little hypocritically.
