The soul crystal currently in Zidi's hand has dropped below 20.

The soul crystal in her hand has never been replenished since she first obtained it.

In fact, she had nothing to add.

One piece is used and one piece is lost, now it is less than 20 yuan.

The resources for undead cultivation that Zidi obtained basically came from Cang Xu.

To be honest, she was able to advance to the Black Iron Level Necromancer so quickly, thanks to Cang Xu.

"Before I am officially resurrected, if I want to maintain this pace of practice, I have to find new undead resources." Zidi frowned again, falling into distress.

It is so easy to collect undead resources.

The situation of the Necromancer has always been bad, and everyone around the world is calling for a fight. Just looking for relevant channels is difficult to solve. Many forces are secretly setting traps, releasing black market and other fake news to lure the Necromancer to show up.

Zidi has other important things to do now and has no time to do this.

"If I act in my current capacity and are exposed, the harm to the Dragon and Lion Mercenary Group will be too great. We cannot bear the consequences."

"So, I can only ask Cang Xu."

Zidi sighed in her heart.

She has always retained a lot of trust and expectations for her companions.

On the one hand, this is the experience of struggling to survive on the Mysterious Island that forged her mentality. On the other hand, it is the characteristics of her businessman.

Businessmen are good at communication and good at using connections to leverage resources and make profits.

Just because I can't do something doesn't mean others can't do it.

Others can, and through cooperation, I can also benefit and overcome the limitations of my own abilities.

This is the cooperative thinking of businessmen.

Because of this, when the dragon boy persuaded Zidi to share the blood core with others, Zidi quickly agreed.

This is not only Zidi’s deep love for the boy, but also her own cognition and values ​​that contributed to her judgment.

Zidi began to meditate to accumulate mana for the expanded mana pool after the upgrade.

Although the mage can leverage external elemental energy, he must also have savings in his own mana pool. Just like the principal of a businessman, the larger the principal, the more funds can be leveraged.

"Compared to the bronze level, the undead mana pool of the black iron level has expanded more than twice. Compared with the fire mana pool of my lifetime, it is twice as large, and my mental power has become stronger." Zi Di secretly compared.

This is a unique practice experience that most mages will not have.

"But compared with the body after blood purification, the current meditation efficiency is still far behind!"

This gap is quite obvious.

The blood in Zidi's body has been purified. Like the cyanobacteria, it is extremely pure, reaching 100%. Unlike the cyanobacteria, her gunpowder flower blood is gold-level, higher than the silver-level fish bladder blood.

Speaking of which, Zidi originally wanted to create a passive meditation practice environment so that her body's mage level could be continuously improved.

Unfortunately, there was an accident on Lan Zhao's side, and the Dragon Man boy commanded the Deep Sea Monster Fish to pursue her for rescue, and also took away her body.

Before they parted, the two of them also thought about letting Zidi take her body on the road to the Ice Sculpture Capital.

But after careful consideration, both of them felt that this move was too risky. Once discovered, the details of Zidi's undead life would be exposed. It would be even worse if they encountered danger on the road and Zidi's body was destroyed.

Judging from the ambush battle in Cold Wind Valley, the concerns of the dragon boy and Zidi were correct.

They also made the right choice - keeping Zidi's body in the Deep Sea Monster Fish.

Zidi can control her body through the Soul Resurrection Technique. This cannot be regarded as a true resurrection. Meditation is also very difficult and there are many distractions. But even so, the meditation efficiency in this state is much stronger than her current state.

Gold level bloodline is really excellent!

After the experience, Zidi was unforgettable.

"My current ghost life form, the black iron level should be its limit." With more experience in this area, Zidi also has a more accurate estimate.

Generally speaking, the transformation of normal life into undead life does not necessarily mean an increase in qualifications.

Cang Xu is like this because he was selected from the soul inheritance implicit in the oil painting. He has been tested and has the qualifications to practice necromancy.

Zidi has not directly come into contact with the inheritance of the undead, but the results of her own successful practice also prove that she is qualified to practice the undead law system.

However, after practice, Zidi became more and more aware that her cultivation qualifications were also limited.

Zidi is not frustrated, in fact, she is very satisfied.

It was this qualification that prevented her from completely losing her life on the mysterious island. Although she has now transformed into an undead life, there is still a glimmer of hope that she can be resurrected.

"Besides, there is no room for improvement in my undead qualifications."

"As long as I find the answer and know what my undead bloodline is. Then purify it. As long as my current bloodline concentration is not 100%, there is room for improvement."

Although Zidi can use magic medicine to test blood, the scope of the test is limited to normal life and cannot determine the life of the undead.

This is beyond her knowledge.

Cang Xu shared with her all the undead inheritance he had obtained from Songfeng Island.

But these inheritances are either basic level or low level, and do not have bloodline knowledge.

The undead law system has developed a spell that can directly detect the bloodline and cultivation qualifications of the undead, but this spell is included in the mid-level undead inheritance. Cang Xu has not yet obtained it from the ship ghost.

The efficiency of Zidi meditation is not high.

On the one hand, it is the limitation of bloodline, and on the other hand, it is the lack of negative energy.

Generally speaking, places suitable for necromancer practice are cemeteries, mass graves, ancient battlefields, etc.

And she is now in the center of Blood City.

Fortunately, she still has undead resources in her hands, which can provide negative energy.

Doing so is actually quite wasteful. These undead resources can be used as alchemy materials, etc. If the negative energy is extracted and used for meditation, these resources are basically useless. Even if they still have remaining value, their value will be greatly reduced.

Not only that, in order to cover up the fluctuations of negative energy and prevent the secret from being exposed, Zidi had to lay out a magic circle to cover it up.

She is not worried that her identity will be exposed because of the undead practice.

Her main confidence lies in the art of deception and disguise.

So far, this spell has never failed.

However, this is also a waste. The cost is hard to estimate - pearl foam is a god-level material!

By the time Zidi's newly expanded mana pool was sufficient, it was already late at night.

On the contrary, her spirit is shining. As a ghost, she does not need to sleep at all. She will only fall into a dormant state unless her spirit is extremely exhausted.

Zidi summoned some ghosts and began to transform them.

Among the inheritance of the undead obtained from Cang Xu, Zi Di majored in soul veins.

In the low-level inheritance of soul veins, the most important content is that the necromancer transforms the basic ghosts and improves them comprehensively or specifically.

This is the cornerstone of an army of necromancers.

There are only two kinds of ghosts transformed by Zidi, one is the snake soul, and the other is the rat soul.

Almost all of these ghosts originate from Snake and Rat Island.

On Snake Island, she obtained a large number of ghosts by killing tide snakes and molten rats.

According to the methods in the low-level inheritance of the undead, she is transforming the snake soul into a snake shadow ghost and the rat soul into a rat-eyed ghost.

The Snake Shadow Ghost can blend into the shadows and hide. It can secretly track targets and mark the Necromancer within a certain range.

Rat-eyed ghosts have strengthened their detection capabilities.

"After becoming a black iron level, my ability to transform ghosts has also improved a lot."

The effect of increasing the mage level can be said to be immediate.

Soon after, all the mana in Zi Di's body was exhausted.

She meditated again, drawing negative energy from the undead material.

Soon, it was used up again.

After going back and forth for several rounds, a lot of undead materials were consumed, but more than twenty black iron-level transformed ghosts were obtained.

"Fortunately, transforming ghosts is a necromancy technique, not an alchemical technique." Zi Di exhaled a turbid breath.

After hesitating for a moment, she decided to use the deception and disguise array.

She took out the array tiles and quickly put them together.

She had practiced this step extensively in advance, in order to prevent future emergencies and the actual effect of the deception and camouflage technique needed to be adjusted immediately.

Compared with the blood purification array, the construction of the deception and camouflage array is not complicated. Back then, Zidi and Cangxu completed the construction of the first deception and camouflage array.

After having the portable array board, Zidi immediately secretly set out to build a second set of deception and camouflage arrays.

This also prevents future accidents.

It would be terrible if the first set of deception and camouflage array broke down and the survivors were waiting for emergency use.
