Shi Yi played with the smooth and round things in his hands, like metal spheres.

It wasn't metal, it was the shell of the entity's soul.

At this time, Shi Yi had been out of the mirror world for three days, and in the past three days, Shi Yi had been dealing with the physical souls he had brought back from the top floor of the pagoda.

In order to prevent the soul body's body from breaking, Shi Yi adopted the method of fire refining, and used the Dan furnace to calcinate the body to melt this layer of body, and finally peeled off this special body from the soul body.

Shi Yi brought back more than a hundred soul bodies from the mirror world, and finally harvested this fist-sized body shell material.

This special material is very valuable, and if it is used as a disposable defensive weapon, opening it in front of you when attacked, the enemy will inevitably be shattered and devoured.

Or with its characteristics of being more powerful the farther away, using the fragmentation characteristic to snipe opponents from a distance is also a sharp weapon for Yin people.

Although this Mirror Shatter Attack has been severely weakened after leaving the Mirror World, it can cause serious injury or even death with a single blow.

However, with its Shatter Attack, which is almost impossible to dodge after launching, it is still a powerful weapon against the enemy.

Being able to harvest this special resource, Shi Yi is still quite satisfied.

Originally, Shi Yi thought that this was the biggest gain of this trip to the mirror world.

But when Shi Yi saw the soul that had condensed into a crystalline entity after the shell was peeled off, Shi Yi realized that he was wrong.

Looking at the crystalline soul that slowly disintegrates like a flower in your hand.

If there is no special means or physical preservation, the soul will dissipate and fall into the cycle of heaven and earth because it cannot be maintained.

Under normal circumstances, the soul cannot contact the present world, and it is very difficult for the person in the present world to reach the soul.

The crystalline soul in Shi Yi's hand has changed this, although it is still dissipating and withering, but it really exists in Shi Yi's hand.

Immediately, Shi Yi held the crystalline soul in his hand, and at the same time that the soul body shattered and scattered, a pure soul power was also injected into Shi Yi's body.

Shi Yi suddenly felt that his spirit was lifted, his mind was clear, and even his five senses became a lot sharper.

This boosting effect is different from the physical state brought about by the essence blood, but comes from the mental changes brought about by the soul body being enhanced by the soul power.

There is a significant difference between the essence and blood acting on the body and the soul power acting on the soul.

Besides, soul power is far more precious than essence blood.

It can be said that a person's soul power has been a quantity from the beginning, and it will only continue to decrease and it is difficult to increase.

The image of some people's souls is like a furnace, and soul power is the fuel of firewood and grass.

People live between heaven and earth, burning soul power all the time.

For mortals, it doesn't matter how much soul power they have, because few of them live to the end of their lives, when their soul power is exhausted.

But the monk is different, the monk's physical strength as long as it is not an accident, the physical body is not the key to restricting the monk's longevity at all.

At the end of the day, it's enough to take away the house and change it to a young body.

Therefore, if a monk wants to live a long time, the only restriction is on this soul power.

If you want to live forever in the world, you must ensure that the soul fire is endless, and adding soul power that symbolizes firewood to the soul is the only means.

However, the soul of a living person is different from that of ghosts, and the biggest difference between the two is soul power.

Souls need to consume soul power to maintain their own stability, while ghosts do not need soul power, they only need to devour their own kind to maintain their existence.

The means of enhancing soul power are very rare, and it is difficult to find a way to directly increase soul power other than improving realm cultivation.

Even a soul path cultivator who has a very deep study of souls cannot increase his soul power.

The methods used by the Soul Dao School to nourish the soul and strengthen the soul are only based on the existing soul power, making it more durable.

In this way, the soul path cultivator can use a smaller soul power consumption to accomplish a series of things that other schools can't do, such as splitting souls, seizing houses, and so on.

For monks, soul power is equivalent to lifespan, and no one will dislike too much soul power.

The increase in soul power with each advance is far from enough for most monks.

This is especially true for monks who are at the end of their lives, but are still stuck on the path of advancement.

In this way, the value of the crystalline soul that can directly increase the soul power is self-evident.

Moreover, the role of soul power is not only to increase the life span of monks, but also to reach a certain level of soul power, which can not only see the soul with the naked eye, but also enable people to have a magical power called the eye of the heart.

It can greatly strengthen people's mental ability to predict the coming of danger, which is far better than any prophetic talisman.

With Shi Yi leaving the battlefield, the inadequacy of the heart talisman that can only predict the threat to his life and cannot predict other dangers has been exposed.

Shi Yi had already planned to add another means of precognition, but the original target was other types of precognitive runes.

Now that he has mastered the mirror world, the way to obtain soul power, Shi Yi naturally takes accumulating soul power to a certain extent and obtaining the supernatural power of the heart eye as the highest priority.

It can increase longevity and gain a great ability to predict, so why not.

After having a goal, Shi Yi will not give up entering the mirror world even more.

This time back, Shi Yi needs to buy some things before he can enter the mirror world again.

Especially the means related to sealing the soul, this time because this situation was not expected, so the only expedient measure such as storage pockets can be used to pretend to the soul.

If he stays in the mirror world for a long time, when Shi Yi returns to the present world, it is estimated that only the shell of these entity souls will be lost, so Shi Yi will not be distressed to death.

In order to avoid this kind of problem, the means of sealing the soul must be prepared.

In addition, in the face of Yaoluo and Mingxia, the two forces that want to make small moves at the first opportunity, they also need to make more preparations.

At least, before receiving supernatural powers, additional means of foreknowledge are still needed, and it is impossible to be too careful to deal with such a large force with bad intentions.

In addition, now that Shi Yi has advanced to the Fetal Breath Realm, the pills he will take for daily cultivation in the future will be mainly based on the Illusory Pill.

In the past, the Naqi Pill taken during the Fu Qi Period, in addition to replenishing the Heaven and Earth Yuan Qi, was also somewhat useful, and could only be reduced to trading currency.

It is foreseeable that in order to save the key to enter the mirror world, Shi Yi will stay in it for a long time.

In order not to delay daily cultivation, the Illusory Pill also needs to be prepared.

Originally, Shi Yi wanted to try to refine the Illusory Shadow Pill, but after reaching the middle level, Fan Huo was no longer suitable for alchemy.

This is the embarrassment of the non-Heart Fire Dao alchemist, for this headache, Shi Yi can only temporarily suppress it, and buy the finished pill first.

Fortunately, the family wealth that Yishi Yi saved in the three years of Liu Guo was not so bad that he couldn't afford to buy the Phantom Pill.

There are so many of the above things to buy, which is why Shi Yi is in a hurry to return.
