At the beginning, I cleaned the Sutra Library and completed the incomplete skills.

Originally lifeless, the purple sandalwood core reacted suddenly after Li Lan took out the spirit stone.

The rich spiritual energy of heaven and earth emitted from the spirit stone gradually dissipated around it.

The purple sandalwood core seemed to sense the flow of spiritual energy in the surroundings. The deep rings suddenly flickered, as if breathing.

Given time,

as if attracted, the spiritual energy of heaven and earth, like nimble silk threads, quietly converged towards it.

These spiritual energies first circled around it, as if testing,

and then, eagerly, they seeped into the wood of the purple sandalwood core.

As the spiritual energy continued to gather,

the purple sandalwood core seemed to become an invisible vortex center,

drawing the surrounding space into a state of vitality as well.

Seeing this scene,

a look of surprise flashed in Li Lan's eyes.

He could clearly see that

this purple sandalwood core was actually cultivating!

And from his perception,

the speed at which this tree core refined the spiritual energy of heaven and earth

was actually far greater than his own.

This couldn't help but make Li Lan feel a little depressed.

His spiritual root aptitude was indeed poor enough,

to the point where even a tree core surpassed him in terms of cultivation speed.

However,

when he thought that he had only been cultivating for a little over ten years,

while this old tree had been cultivating for five hundred years,

Li Lan quickly felt relieved.

When this purple sandalwood spirit tree was first born, its talent during its seedling stage was certainly at the bottom compared to those rare and precious spirit plants.

Its current speed of absorbing spiritual energy

was mostly due to the accumulation of time, which allowed it to wash away its ordinariness and defy fate.

A tree without intelligence

could still achieve this level,

so why couldn't Li Lan, with his arms and legs, do the same?

Li Lan was not discouraged by this,

but instead felt encouraged by it.

However,

he soon thought of something else, and his brow furrowed slightly.

With this tree here,

most of the spiritual energy of heaven and earth in the cave would be taken away by it,

and the effect of his cultivation here would inevitably be greatly reduced.

In addition to this,

what was even more troublesome was that

Li Lan was worried that after this tree absorbed enough spiritual energy of heaven and earth,

it would regain its Foundation Establishment stage strength.

You must know that

he was only at the sixth level of Qi Refining stage now.

If this tree really recovered its strength and summoned those dark vines again,

Li Lan would only have the option of running away.

But to give up like this, this five-hundred-year-old spiritual material that he had finally obtained,

would probably be unbearable for anyone.

This must not be allowed to happen.

Having made up his mind,

Li Lan stepped forward and picked up the purple sandalwood core.

He prepared to put it back into his storage bag,

and would not take it out again easily until he had figured out how to maximize the use of this spiritual plant.

However,

what he didn't expect was that

just as his hands touched the purple sandalwood core,

another unexpected change occurred.

Li Lan discovered that

those spiritual energies that had been refined by the purple sandalwood core

were now scurrying around in the tree core like headless flies.

At this moment, as he came into contact with the purple sandalwood core,

these spiritual energies seemed to suddenly have a target,

and rushed into his body one after another.

These spiritual energies had already been refined once by the purple sandalwood core. At this moment, when they entered Li Lan's body, after simply circulating through his meridians,

they turned into pure mana and merged into his dantian.

Since embarking on the path of immortality,

it was the first time he had experienced such an easy feeling of refining the spiritual energy of heaven and earth.

Even Li Lan, whose temperament had always been calm and collected,

couldn't help but be a little stunned at this moment.

This purple sandalwood spirit tree core could actually help cultivators transform the spiritual energy of heaven and earth and assist in cultivation?

Li Lan carefully recalled the previous feeling,

and the spiritual energy refined by the purple sandalwood core did not cause any rejection reaction when it entered his body.

This feeling was as natural as when he was quenching the Treasure Judge Pen, infusing it with mana and then taking it back into his body.

The difference was that

previously, Li Lan took the initiative to refine the spiritual energy to nourish the treasure.

But now, it was as if this purple sandalwood core was refining the spiritual energy and nourishing him in return.

No wonder even the Great Elder, who was in the middle stage of Foundation Establishment, was so concerned about this five-hundred-year-old purple sandalwood spirit tree.

It turned out that this thing had such a strange effect.

Li Lan was both surprised and delighted at this moment.

With this thing,

his speed of refining the spiritual energy of heaven and earth could be increased several times over.

Coupled with the abundant spiritual energy provided by this spirit stone cave, even compared to those with true spiritual roots, he would not be at a disadvantage at all.

After a moment of joy,

Li Lan quickly calmed down.

He couldn't help but ponder the reasons behind this.

Was it that all five-hundred-year-old spiritual plants were like this,

or was it that only this purple sandalwood spirit tree had this effect?

Li Lan couldn't help but think of what the Great Elder had said before.

Spiritual plants that had become spirits, like demon beasts forming inner cores, would cultivate a tree core in their bodies.

If all spiritual plants or demon beasts that had become spirits could have this effect,

then cultivation would be much simpler for cultivators.

Even those with five-attribute pseudo-spiritual roots,

could hold a five-hundred-year-old, or even a thousand-year-old, spiritual plant,

and obtain a speed of refining spiritual energy that was not weaker than a true spiritual root. However, Li Lan only thought about this idea.

Not to mention how difficult it was for spiritual plants and demon beasts to become spirits and form inner cores,

just growing undisturbed to five hundred years old

was quite difficult in this immortal cultivation world that highly valued cultivation resources.

Unless they were hidden in some undiscovered relics,

it was extremely difficult for spiritual plants in the wilderness to grow safely to maturity.

As for special cultivation, it was even more difficult.

Even for cultivators, five hundred years was too long.

It often required the joint cultivation of two or even three generations of cultivators to achieve it.

This was just the most ideal situation,

you must know that

the immortal cultivation world was not always calm and peaceful.

In this immortal cultivation world, which was far more cruel than the mortal world, few families or sects dared to pat their chests and guarantee that their families would be able to continue to exist forever.

In this precarious situation,

which cultivator would be willing to spend five hundred years

and use the time of three generations to cultivate a spiritual plant that was so old?

Of course.

There were always exceptions to everything,

perhaps on this land,

there really were such detached aristocratic immortal clans that specialized in cultivating these kinds of long-lived

spiritual plants to assist in cultivation and provide them to their descendants, but because of their low profile, they were not known to the world.

But no matter what,

the value of this five-hundred-year-old purple sandalwood core

was immeasurable for Li Lan.

Its ability to pre-filter the spiritual energy of heaven and earth and enhance the speed of cultivation

was indeed what he needed most at the moment.

It would not be an exaggeration to say that the appearance of the purple sandalwood core had truly solved his immediate problem.

What was even better was that

by taking away the spiritual energy that the tree core had refined,

he would not have to worry about the other party becoming the dominant force due to the excessive speed of cultivation.
