A few days later, Zhang Ling held a purple jade bottle, inside which were cyan-black pills.
"I wonder how effective this pill is."
This is a lightning-attributed pill called Azure Lightning Pill. Although it is a grade three spirit medicine, it is condensed from Azure Lightning Flower and some auxiliary materials. Few people other than cultivators who practice lightning-attributed techniques would refine this kind of pill.
With a flash of black light in his hand, the black stone mirror appeared.
The main purpose of refining the Azure Lightning Pill is to practice the Lightning Essence Nurturing Spirit Art, to prepare for breaking through to the Nascent Soul stage.
By combining it with the Water Astral Divine Lightning in the stone mirror, he can begin to practice this secret technique.
The Lightning Essence Nurturing Spirit Art is divided into three layers. The first layer requires initially guiding lightning into the body and condensing a lightning light curse within the body, which poses a considerable danger.
The most direct method is to directly guide heavenly lightning into the body, which is the fastest but also the most dangerous. It requires an extremely strong physical body. Without powerful recovery ability, a single strike of heavenly lightning can severely injure a cultivator.
The minimum requirement for cultivating this secret technique is to reach the Golden Core stage, otherwise, one cannot withstand the heavenly lightning entering the body.
Fortunately, there are some clever methods. In the initial stages of cultivation, few people can withstand heavenly lightning entering the body, which is why auxiliary pills like the Azure Lightning Pill exist.
Although lightning-attributed pills also gather a lot of lightning-attributed spiritual power, they are much gentler than natural heavenly lightning.
Even with the mysterious small bead that can catalyze spirit herbs, Zhang Ling searched through many pill formulas before settling on the Azure Lightning Pill as an aid.
As for whether it's suitable, he can't be completely sure. He has to try it to know.
Over the next two months, Zhang Ling catalyzed several kinds of lightning-attributed spirit trees and collected some lightning-attributed ores to refine a set of Lightning Essence Formation, the Yin-Yang Lightning Light Formation.
This formation also assists in the cultivation of the Lightning Essence Nurturing Spirit Art.
The most difficult part of refining the formation's array disks and deployment tools is engraving the formation's spiritual patterns. Fortunately, there are detailed formation blueprints in the secret technique, and he has some experience in this area, so he successfully refined it after spending some time.
After refining the formation, Zhang Ling spent a few more days dealing with some trivial matters. The tasks of cultivating the Earth Spirit Bees and Ice Spirit Silkworms were handed over to the Corpse Bear. After all, he lost nearly 20,000 spirit bees during his trip to the Hidden Demon Valley. Cultivating the Earth Spirit Bees is not easy, and it will take five or six years to restore them to their original size.
At the same time, he also purchased several rank one and two puppets from several shops in Myriad Manifestation City to take care of the spirit fields.
After preparing everything, he went directly to the volcanic area in the south of Fire Cloud Island, where he built a secret chamber about forty to fifty zhang in size and began to cultivate the secret technique.
It is most suitable to set up the Yin-Yang Lightning Light Formation here because he is about to introduce Yin-attributed Water Astral Divine Lightning into his body.
This is also the first layer of cultivation for the secret technique: introducing a Yin-attributed or Yang-attributed lightning into the body to condense a Lightning Light Curse.
After entering the secret chamber, Zhang Ling immediately released more than a dozen array flags of various colors to set up the formation, isolating the surrounding fire spiritual power.
Finally, he took out the black stone mirror and a cyan wooden stick. With a wave of his hand, the cyan wooden stick slowly flew into the air, constantly rotating and revealing streaks of cyan-white lightning.
This is a three-thousand-year-old Yang Lightning Wood, and combined with the stone mirror that can release Water Astral Divine Lightning, they are the two array eyes of this Yin-Yang Lightning Light Formation.
Using magical treasures as array eyes is also very common.
His hands formed a series of hand seals, and the cyan wooden stick flew slowly towards a specific position on the left, inserting itself into the ground with a clang. The lightning flashing on it transformed into a huge spirit tree ten zhang tall and as thick as an arm.
The stone mirror also quickly rotated and landed in a position on the right, with blue-black lightning constantly jumping within.
Then, Zhang Ling stomped his foot on the ground, and a circular platform rose up beneath him with a flash of spiritual light. He flashed and sat cross-legged on the platform. Then, with a wave of his hand, a cyan-black array disk settled above his head. This is the array disk of the Yin-Yang Lightning Light Formation, used to adjust the strength of the lightning spiritual power in the formation.
Zhang Ling sat quietly on the circular platform, closing his eyes to rest. Soon after, a layer of strange mist floated in the secret chamber.
The mist was divided into two layers: a cyan-white layer gathered above his head, and a black-blue layer spread beneath his feet. The two layers of mist seemed distinct, but both revealed streaks of lightning.
After sitting quietly for more than an hour, Zhang Ling opened his eyes, and a low murmur came from his mouth. His hands formed a series of strange hand seals and struck the array disk.
Immediately, the array disk lit up with cyan light and black light. The two layers of spiritual light intertwined and transformed into a cyan lightning bolt and a black lightning arc.
Zhang Ling took a deep breath, recalled the Lightning Essence Nurturing Spirit Art in his mind, and without further hesitation, sent a magic incantation upwards, merging into the array disk. Immediately, the formation light sphere dropped a layer of cyan-black lightning light, covering him.
An Azure Lightning Pill appeared in his hand, and he quickly threw it into his mouth. He closed his eyes and quickly formed hand seals.
As soon as this lightning-attributed pill entered his mouth, Zhang Ling felt a sense of numbness and itching spread throughout his body. At the same time, his body twitched involuntarily. A layer of light cyan lightning immediately appeared on the surface of his body. He quickly exerted all his spiritual power, forcibly gathering the lightning spiritual power contained in the pill in his dantian, coiling it into a lightning light rune.
This step took a full two hours, and Zhang Ling dared not be careless in the slightest.
If it weren't for the thick Earth spiritual power in his body, constantly enveloping the lightning-attributed spiritual power, allowing this group of lightning spiritual power to spread in his body, he would be injured instantly.
After completing this step, Zhang Ling opened his eyes, and then came the most important part. With a wave of his hand, a ray of spiritual light struck the array disk.
The black stone mirror, which he had placed in a specific position within the formation, suddenly flashed with black light, releasing two or three strands of black lightning as thin as hair.
Instantly, the layer of cyan-black lightning cover outside Zhang Ling's body turned black-blue. It swelled and contracted a few times, covering the surface of his body.
Then, he closed his eyes again and began to cultivate, but after a dozen breaths of time, an unexpected change occurred. The lightning light on his body shattered, and Zhang Ling instantly spat out a mouthful of blood. But he couldn't care about his injuries and quickly slammed his chest, spitting out a ball of yellow light.
The yellow light was wrapped around a ball of cyan light. As soon as it flew away from his body, it exploded with a bang, and a dozen lightning bolts exploded into a ball of cyan-black sparks.
Zhang Ling's complexion improved slightly. Looking inside his body, he saw that there were still a few strands of Water Astral Divine Lightning remaining in his dantian. He quickly mobilized his spiritual power and spent a quarter of an hour to eliminate these Yin Lightning.
Water Astral Divine Lightning belongs to Yin Lightning, which is not as explosive as Yang Lightning, but the characteristic of Yin Lightning is that it is difficult to deal with like a maggot attached to a bone. If not handled properly, it may damage the dantian and form hidden injuries.
"What's going on?" he muttered to himself with a gloomy expression.
