Immortality and cultivation begin with alchemy and accounting.

In addition to nurturing the Yin Souls to strengthen the "spirit" of the Yin Soul Array, upgrading the Yin Soul Array also requires the addition of some spiritual materials to improve the material of the Yin Soul Array itself.

It is said to have bypassed the three hurdles of "essence, energy, and spirit" required for ordinary cultivators to establish their foundation.

In Bai Xuanjing's view, it was simply a matter of transferring these three trials from the cultivator himself to external objects.

Although the foundation-building method of the Yin Soul Scripture is debatable, Bai Xuanjing believes that the Yin Soul Array is indeed a good means of fighting enemies.

There are two ways to create a Yin spirit. One way is to nurture it in an extremely Yin place, where a soul can be born naturally and evolve into a Yin spirit.

This process is rather slow.

Another method is to extract Yin Souls directly from the bodies of other cultivators through killing.

The latter is undoubtedly faster and more in line with the style of the demonic path.

"The Yin Old Ghost's Yin Soul Array is originally a first-class high-grade item."

Even without upgrading it, simply refining this array and nurturing its core for a period of time would allow it to be used directly; it could be kept as a tool.

Bai Xuanjing thought to himself.

Compared to magical artifacts, the greatest advantage of the Yin Soul Array is that when it is used, the cultivator only needs to give the command, and the array core and the Yin Souls can fight against the enemy.

Throughout the process, what is consumed is the Yin Soul Array's own Yin Soul and Yin Energy.

Afterwards, the cultivator can replenish the consumed Yin energy by nourishing it with their own magical power, Yin energy, or by adding new Yin spirits.

It is even possible to use one's essence and blood to forcibly stimulate the Yin energy within a Yin spirit during a battle, thereby unleashing the potential of the Yin Spirit Array.

Therefore, cultivators need to pour very little mana into the Yin Soul Array during combat, far less than a first-grade high-quality magic weapon.

Even a mid-stage Qi Refining cultivator can use it.

It is somewhat similar to a corpse puppet.

Thinking of this, Bai Xuanjing first put the array flag into his storage bag, intending to refine it in the future and use it as a means of protection.

Speaking of corpse puppets...

Both of the blue-armored leopards were injured in the process of dealing with Yin Laogui.

One of them even had a broken leg.

The Corpse Puppet Techniques that Bai Xuanjing obtained did not include the method of Corpse Puppet Repair, so the power of the Corpse Puppet would decrease after it was injured.

Moreover, this result is irreversible.

Bai Xuanjing didn't seem to care much about this.

Even without combat losses, the Azure Armored Leopard Corpse Puppet will slowly decay after it is created.

For him, the cost of crafting a blue-armored leopard corpse puppet was only a little over a hundred low-grade spirit stones.

Compared to Wang Xing, Yin Laogui had more spirit stone crystals in his storage bag. Together, the two of them had a total of 1,800 low-grade spirit stone crystals.

Not to mention there are so many magical artifacts.

Even if the Blue-Armored Leopard is completely destroyed, it's still a profit.

After putting away the "Yin Hun Jing" (Scripture of the Yin Soul), Bai Xuanjing began searching for it again.

Yin Laogui's storage bag contained quite a few pills.

Bai Xuanjing opened and examined them one by one, and soon showed a look of disappointment.

These pills are either ordinary pills from the Vast Ocean or blood pills refined from the flesh and blood of cultivators.

Most elixirs are used for refining qi and healing injuries; there are no elixirs that can temporarily and directly increase one's cultivation level.

Before long, Bai Xuanjing held a gold page in his hand, looking thoughtful.

These gold pages are also a kind of record of the path of cultivation, like a handbook.

The above is a spell called "Spirit Division Technique".

This technique involves a cultivator taking out a spiritual object that matches their own cultivation level and using a spirit-splitting technique to inject a portion of their own cultivation into that spiritual object.

Afterwards, the cultivator's cultivation level will appear lower to outsiders, but it can be restored immediately after absorbing spiritual objects again.

"This technique essentially treats the cultivator as a reservoir, and uses the spirit-dividing technique as the reservoir itself."

"After casting the spell, the apparent decrease in a cultivator's cultivation level is real. Therefore, even if a cultivator's cultivation level is much higher than the one casting the spell, they will not be able to detect anything."

"If you need to restore your cultivation level, you can simply devour the carrier of the Spirit Division Technique; there are no restrictions."

A strange light flickered in Bai Xuanjing's eyes.

He understood.

When Yin Laogui swallowed the pill, his cultivation level increased dramatically, but this was not due to the pill's own effects.

It was because Yin Laogui was originally at the seventh level of Qi Refining, but he used the Spirit Splitting Technique to inject his own cultivation into the pill, thus concealing one level!

Besides first-tier mid-grade pills, first-tier mid-grade spirit ores and other similar items can theoretically also serve as carriers for the Spirit Division Technique.

To outsiders, this technique might seem somewhat useless, its only function being to conceal one's cultivation level.

Although the effect was good, it was said that even high-level cultivators could not see through it.

However, each use requires a spiritual object that matches one's own cultivation level, which unnecessarily increases the consumption.

For independent cultivators, its effect may be far less than practicing a common breath-concealing technique.

But in Bai Xuanjing's view, this spirit-splitting technique was quite useful.

"Currently, my cultivation level is at the mid-stage of Qi Refining. Theoretically, a single mid-grade first-level pill can take away one level of my cultivation, and I can recover by taking another pill."

In this way, even if my cultivation level increases rapidly in a short period of time, I will need to use the Spirit Splitting Technique to seal a portion of my cultivation into a pill, without worrying about outsiders seeing through it.

"When this part of your cultivation is needed, you can take a pill to break the restriction of the Spirit Division Technique and instantly restore your strength."

"nice one!"

Bai Xuanjing's eyes gleamed as she carefully put away the gold page.

That old ghost Yin has quite a few good things on him!

After tidying up, Bai Xuanjing kept only the long nail magic artifact.

He planned to test whether he could use a first-grade high-level magic weapon at will with his current strength, and this long nail was quite suitable.

Moreover, judging from the way Yin Laogui used it, these long nails, when gathered together, are a first-grade high-quality item, and when scattered, they are three first-grade mid-quality magic weapons.

It is a complete set of ritual implements.

Having made up her mind, Bai Xuanjing began to try to infuse her magic power into the long nail and start refining it.

The first step in refining this second-hand magical artifact is to erase the divine soul and magical power imprint left by the previous owner, which takes a little longer.

……

I thought Bai Qingjian would not return for a while.

As evening approached, Bai Xuanjing, who was refining the long nail magic weapon, noticed a conversation coming from the courtyard.

One of the voices was at a normal volume; it belonged to Bai Qingshao.

The other voice was louder and had a distinctive tone; it was a booming voice.

Bai Xuanjing quickly put away the magical artifacts and opened the door.

In the courtyard, Bai Qingshao and Bai Qingjian were heading towards Bai Xuanjing's house, one after the other.

Bai Qingjian is also depicted as an old man, but although his face is aged, he looks quite robust and walks with a slow, tiger-like gait.

"Xuanjing, did you encounter a demonic cultivator in the open sea?"

Although he had never met Bai Xuanjing, Bai Qingjian naturally knew Bai Xuanjing's basic information after Bai Qingshao's introduction.

He seemed quite outgoing, greeting everyone in a very casual manner upon meeting them.

Bai Xuanjing quickly bowed.

"Come and sit down for a while."

Bai Qingjian immediately called out, then plopped down on the stone bench in the center of the courtyard.

"Well, actually, there's something else. That Wang family cultivator was following you earlier, but I can't say it outright..."

Bai Qingshao glanced around and, sensing that there were no means of detection in the surroundings, cautiously set up a soundproofing spell before speaking in a low voice.

"Hmm? A spirit stone vein!"

Upon hearing Bai Qingshao's words, Bai Qingjian's eyes lit up, and his voice unconsciously lowered.

He looked at Bai Xuanjing, slightly surprised: "This kind of opportunity is rare even for the Bai family!"

After saying that, a look of joy immediately appeared on his face.

When this news reached the Bai family, if they could really find that spirit stone mine...

Even if they can't monopolize it, as long as the Bai family can make a profit, not only Bai Xuanjing, but also Bai Qingshao can benefit from it.

"This matter should be reported to the family as soon as possible!"

Bai Qingjian looked at Bai Qingshao with a solemn expression.

Bai Qingshao nodded and stroked his beard, saying, "Right now, the True Man is leading my Bai family cultivators to conquer Jinlan Island. According to the information we received last time, the battle should be coming to an end."

"Jinlan Island is not too far from Jing'an Fang City."

If the message can be delivered to the real person in time, the Bai family's warships, after diverting from Jinlan Island and traveling at full speed, will reach Jing'an Market in less than ten days!

"This opportunity should belong to the Bai family!"

The four major families in Jing'an Fang City are just ordinary Foundation Establishment Immortal Clans, with only one or two Foundation Establishment cultivators in each family.

As long as the Bai family can seize the time to arrive at Jing'an Market, this spirit stone mine will undoubtedly become theirs.

"There's no time to lose. Qing Shao, you must use the spirit boat to travel to the waters off Jinlan Island tonight and deliver this message to the True Person in person!"

Bai Qingjian made the arrangements.

Although they were both the garrison commanders of Jing'an Ward and had the same official status, they were not equal in name.

However, Bai Qingjian has a more assertive personality, and coupled with his cultivation level of the ninth level of Qi Refining, he seems to be the one in charge.

Fortunately, Bai Qingshao didn't seem to care much about this, and no farcical power struggle occurred.

"wrong!"

After saying that, Bai Qingjian suddenly waved his hand and looked at Bai Qingshao with a somewhat embarrassed expression.

"I almost forgot something..."

"I remember there's a Class C fire vein in the waters off Jing'anfang, right? Qing Shao, do you have the alchemist's communication paper crane?"

After saying that, Bai Qingjian looked at Bai Qingshao hopefully.

Bai Qingshao frowned slightly: "...I'm not a cultivator from the Third Branch either, so how would I know many alchemists?"

"There is indeed a fire vein with the character '丙' in the sea area of ​​Jing'anfang."

I did know that alchemist before; she was the Seventh Old Woman. But she retired five years ago, and her family promoted a new alchemist to the position.

However, that new alchemist lives a secluded life and has never visited the pharmacy even once. To this day, I don't even know who is on assignment there.

Although the guard of the apothecary had information that roughly how many Bai family cultivators were stationed in the nearby sea area.

However, they did not know the specific islands where these monks had been stationed.

If cultivators from the outlying islands take the initiative to contact them, they can learn some additional information.

However, if the cultivators stationed on the outlying islands never visit the apothecary, they wouldn't even know which Bai family cultivators are stationed in Jing'an Market.

"This is a bit tricky!"

Upon hearing this, Bai Qingjian's expression changed.

Upon hearing this, Bai Qingshao quickly realized something, and his expression turned somewhat grim: "You didn't use up all the Rejuvenating Pills, did you?!"
