Su Xia's heart was confused.

She can understand the words on it, but what exactly is a spiritual root?

Couldn't Su Ancestor explain it in more detail?

Where did Su Xia know, in that place in the Immortal Realm, the spiritual root was known to everyone, so there was no introduction in the spiritual cultivation technique.

At this time, Su Xia had calmed down, she knew that it was useless to be anxious, and the top priority was to figure out what the spiritual root was first.

But since there is no spiritual cultivation recipe, there is only -

Su Xia looked at the medicine cabinet against the wall.

The letter from the ancestor of the Su family was very long, and it introduced the spirit ring in detail, and at this time, Su Xia knew that the medicine cabinet against the wall was the treasure of Su Yilu's life.

Since it is a treasure, there should be books...... Right?!

There are nine layers of medicine cabinets, each with three compartments, Su Xia casually found a three-layer medicine cabinet, and found that it was ...... Can't pull it open.

"Is it broken?"

Su Xia thought to herself, and pulled down the cabinet door next to her again, and the result was ...... Still can't pull it open.

"Hey?! I don't believe it yet! ”

Su Xia tried a few more floors, only to find that only the door of the first floor could be opened.

"Is it because the level of the space is too low?"

The medicine cabinet here has nine floors, corresponding to the nine levels of space. And now the space is the first level, so you can only open the medicine cabinet on the first floor?

Su Xia thought about it, and this was the only reason.

But fortunately, the first layer is basically all books, and Su Xia finally found the introduction of Linggen after flipping through three books.

"Fortunately, the words of the fairy realm are in italics!" This is where Su Xia is most fortunate.

Spiritual root: "Spiritual root, everyone in the fairy realm has it since birth, spiritual root is divided into three categories: Yuan Ling root, body spirit root and alien spirit root, Yuan Ling root is a natural common element such as gold, wood, water, fire and earth in nature, body spirit root refers to speed, strength, etc., and the spirit root essence is a special element such as wind, thunder and ice......"

Su Xia looked at it and felt ...... This spiritual root...... Looks like an ability!

There are also abilities divided into gold, wood, water, fire, and earth, as well as thunder and ice, speed, strength, and so on.

Could it be that the ability here is the spiritual root?!

The more Su Xia thought about it, the more she felt that her guess was reasonable.

So she decided to use the ability as a spiritual root and try it if it wasn't right...... Ahem, it must be right anyway!

She happened to find a futon in the corner and dragged it to the middle of the hut to meditate.

Cross-legged, eyes closed, condensed, carefully felt the aura in the air.

I don't know how long it took, it seemed like the vicissitudes of the sea, and it seemed like a white horse passing through the gap, and the room was quiet, and the breath could be heard.

Su Xia felt that she had fallen into a wonderful world, in this world, she could see her body clearly, every meridian, every tissue was clear, and the air was scattered with colorful light clusters, including cyan, red, gold, and black...... Colorful.

"Is this Reiki?"

The red one has a blazing feeling when it is close, the cyan one is constantly spinning, and the golden one can feel the sharp aura at a glance...... This should be a different attribute, red is fire, cyan is wind, green is wood, gold is gold,,,,,

In order to verify her conjecture, she approached the red light cluster closest to her, which was fire spiritual power, and when she touched it lightly, she found that the light cluster turned into a little starlight and integrated into her body when she first touched it.

Su Xia could clearly feel that there was a stream of energy swimming in his body, thinking of what the book said, he hurriedly sank into the dantian and transported that energy to the dantian with his consciousness.

But after arriving at the dantian, Su Xia found that he couldn't stabilize it at all.

The book says that when the aura arrives in the dantian, it will be attracted by the spiritual root by itself, and the cultivation only needs to integrate the spiritual energy into the spiritual root that is suitable for it according to the power of this traction. But Su Xia found that after channeling that aura to the dantian, he didn't feel the so-called traction power. It's like being seated in the right seat, but now, that seat is gone. The aura collided aimlessly in the dantian, and Su Xia couldn't suppress it, "Wow! "Spit out a mouthful of blood.

As soon as the red blood was spit out, Su Xia's face immediately turned pale, but the aura that was originally rushing in his body also dissipated, at least it was not raging in his body.

Su Xia slowed down, and after feeling better, she turned over the spiritual cultivation book again.

"That's right!"

Su Xia carefully compared the contents of it and found that there was nothing wrong.

"Why is it wrong?"

Susha fell into thought.

"Spiritual energy can enter the body, but there is no spiritual root in the dantian to store it...... Why...... ...... Linggen? ”

Suddenly, a flash of inspiration flashed in Su Xia's mind: "In the spiritual cultivation decision, it is said that the dantian is the local of the spiritual root, and it is the source of the cultivator's own spiritual energy, but it is a supernatural person...... It depends on the crystal nucleus in the brain to have a special ability! ”

"Could it be that I shouldn't concentrate the aura to the dantian, but should transport the aura to the brain?"

Su Xia was silent.

The brain is the most delicate part of the human body, and if she guesses wrong, the aura will rage like it did just now, crashing into her brain, and when the time comes, she may become a fool.

Do you just give up?!

Su Xia was a little unwilling.

She thought of her past life, of the days when she was locked up in a dark laboratory, of her parents who died tragically because of her involvement, and of the little spirit who fell into a deep sleep to save herself...... No, she doesn't!

Relive a life, she wants to become stronger!

If you don't succeed, you will be benevolent!

With this mentality, Su Xia re-entered the state of cultivation.

Just like last time, she carefully felt the aura in the air, absorbed it, and slowly sent it to her brain.

This time, she chose a relatively mild wood spirit power.

Su Xia didn't dare to be careless at all, his mind was highly concentrated, and he carefully avoided the neurons in his brain.

Suddenly, she felt an extremely strong suction, almost causing the controlled aura to fly out. Fortunately, it was stabilized in time, but I could still feel the strong suction pulling.

Su Xia's heart was surprised and happy, surprised that the aura almost got out of his hands, and he almost became a fool, when he was happy, his conjecture was correct, and the spiritual root was indeed in his own brain!

Su Xia was even more careful, now that he knew that his conjecture was correct, then next, as long as he followed this traction and found the spiritual root!

Su Xia watched quietly on the side as the green spiritual power was absorbed by a transparent crystal, and with the absorption of the green aura, a stream of green energy also emerged from the crystal.

"This should be your own crystal nucleus!"

Abilities, like zombies, have a crystal nucleus in their brains, which can be absorbed by the Abilities to enhance their abilities. In her previous life, Su Xia had seen her crystal nucleus, she was locked up in the laboratory, and the gang saw that she was worthless, and they were curious about what the crystal nucleus of the five supernatural beings looked like, so they operated on herself and took out the crystal nucleus in her brain.

The crystal nucleus was made into a necklace by blue.

She still remembers the appearance of the crystal nucleus, colorful and beautiful.

The memories ended, and Su Xia suddenly realized that she was practicing, how could she be distracted! And there are four other kinds of aura that need to be introduced!

Su Xia then talked about the other four kinds of spiritual qi according to the original method, and introduced the spiritual root.

As she injected the last aura, she saw that the entire crystal nucleus lit up, and the elements in the air were extremely active, and as she absorbed it, they rushed into her body and were absorbed by the crystal nucleus on its own.

Su Xia continued to cultivate, until she felt a feeling of fullness in the crystal nucleus, and she could no longer absorb it, and then she opened her eyes.
