Ghost tricks, to put it simply, are actually very close to beast control, but they are domesticated ghosts.

The so-called ghost things, in fact, are also born naturally from heaven and earth, between heaven and earth, there are many places, the yin and evil qi is very thick, and it is difficult for demon beasts to survive in this kind of place. Occasionally, demon beasts enter, and sooner or later they will die because the yin qi is too heavy.

But there are exceptions to everything, and some demon beasts with strong vitality will survive in that harsh environment. Over time, these surviving demon beasts, because of the corrosion of yin qi, their fur and flesh will rot away, and they will become half-dead.

This kind of monster is called a ghost thing.

This kind of ghost thing, even if it is beaten to pieces, as long as it lives in a place with sufficient yin qi, it will gradually recover.

For example, the ghost bone wolf demon is, even if it is seriously injured, as long as the soul fire in the skull is not extinguished, and then lives in the yin soul bag, it can slowly recover.

Ghost beasts and spirit beasts are the same, they can cultivate, and they can be promoted to cultivation.

However, its survivability is much stronger than that of spirit beasts, and the fly in the ointment is that ghost beasts need to be cultivated through yin and evil qi, and they can't be like spirit beasts, and they can swallow demon beasts of the same attribute to cultivate, so it is difficult to advance.

"It would be a good choice to have the opportunity to subdue a ghost pet. Shen Yun nodded, his eyes showing interest.

Once the ghost recognizes the master, it will not betray for the rest of its life, which is different from refining the corpse. Once the refining corpse has existed for a long time, it is possible to give birth to spiritual intelligence, which will turn against its master, but the ghost will not.

And once the ghost loses its owner, it can no longer be subdued by other monks. However, in the classics, there are also some methods of forcibly detaining ghosts against the enemy, and it is obvious that this method was used by Nantianxia before, and the ghost bone wolf demon was put into the Yin Soul Bag.

In addition to the ghost trick, there is another kind of ghost secret technique recorded in the classics, which is very practical, the soul extraction technique.

The Soul Extraction Technique also does not need to be cultivated to practice the Ghost Dao Technique, it can be learned.

Monks or demon beasts, when they have just died, their souls will temporarily sit on the corpse for a short period of time, during which time their souls can be stripped from the body through soul extraction, and then sealed with specific tricks and treasures, which can be used later.

This is actually the basis for refining the Beast Soul Talisman.

To refine the beast soul talisman, you first need to extract the soul from the demon beast's body and store it in special treasures, such as soul bowls, soul flags, and the like.

Then, through the soul sealing rune, the soul of the demon beast is sealed into the rune.

Of course, although the demon beast soul is muddy, its innate instinct prompts it to be unwilling to be sealed, so refining the beast soul talisman will needless to say that there will be a certain probability of failure.

It's a pity that after looking at the ghost-like soul sealing rune, Shen Yun felt that his head was big, and he directly gave up his plan to learn to refine the beast soul talisman.

After all, he didn't have a basic talisman making foundation, and talisman making was not a skill that could be learned in a day or two, and most of Shen Yun's usual free time was spent studying formations, so how could he have the time and energy to learn this.

At the back of the classics, there is also the production of soul refining flags, which actually belongs to the category of alchemy.

But what is surprising is that this soul refining banner is actually a magic weapon for growth.

In the Soul Refining Banner, as the number of sealed monks or demon beast souls increases, the power of the Soul Refining Banner will continue to increase.

Of course, this kind of improvement is not unlimited, it depends on the quality of the soul refining banner, it is conceivable that the high-grade soul refining banner is naturally more sealed than the medium-grade soul refining banner, and the power is also more powerful.

Shen Yun's eyes flashed, and he put down the jade slip.

"Do you want to discuss with Feng Botao and use your Qingguang Banner to exchange that soul refining flag?"
