Blood Sacrifice To Millions Of Zombies, I Will Be A Demon Cultivator In The Apocalypse

Chapter 72: Ink Spirit Devourer

The absorbed pure soul energy quickly circulated along Zheng Yi's extraordinary meridians, continuously converging in his hidden acupoints.

With the replenishment of soul essence, the spiritual power formed by the Black Sha Technique rapidly grew stronger.

Whether it was an illusion or not, the originally gathered green flames on his body seemed to darken at this moment, flickering with a faint light, gradually emitting a strange corrosive aura.

Having finally found a Sacred Land suitable for cultivating the Black Sha Technique, Zheng Yi naturally didn't want to leave easily. He no longer wandered around, searching for other locations, but instead stayed directly in this eerie and terrifying mountain hollow to begin closed-door cultivation.

Relying on the blood-clothed female ghost and his subordinates, the Yin Soldiers, Zheng Yi delved deep into this ghost-infested place, capturing vengeful spirits and fierce ghosts to use for cultivation.

This went on for a full half month. In order not to delay his regular cultivation, Zheng Yi's daily expenditure was mostly on spirit stones.

In the doomsday world, there were no spiritual veins, and spiritual energy was extremely scarce. Even if condensed and absorbed through spells, it was only a trace, extremely rare.

This place was indeed unsuitable for cultivators. Fortunately, Zheng Yi brought a large number of low-grade spirit stones for his daily cultivation needs.

But the results were also very fruitful. During this period, he had successfully refined three hundred and thirty to forty vengeful spirits and fierce ghosts. About one-third of the circulating green Xuan Sha in his body had naturally transformed into Ink Spirit Devourer.

Even the demonic flames condensed from his abundant demonic energy had turned into dark green demonic flames, greatly increasing their power.

The corrosive power produced could even directly affect the divine souls and divine thoughts of cultivators, making it a remarkable achievement.

Almost all of the vengeful spirits and fierce ghosts in this mountain hollow were gradually consumed by Zheng Yi, feeding his dark green demonic flame and demonic energy, leaving none behind.

The originally cold and gloomy ghost cave now had a few traces of yang energy, and sunlight was shining in again, dispelling the chill.

Zheng Yi sat cross-legged on the ground, extending his right hand with the palm facing up. The circulation route of the Black Sha Technique within his body quickly ran, and amidst the surging spiritual energy, accompanied by a bang, a violent dark green flame burst forth from his palm.

That flame seemed to have no temperature, causing no harm to Zheng Yi's physical body. It even seemed to possess an unusually icy sensation.

As the dark green demonic flame burned and flickered in Zheng Yi's palm, the temperature of the surrounding air suddenly dropped by two or three degrees.

A layer of fine frost formed on the ground along his body.

With Zheng Yi having refined all the surrounding vengeful spirits and fierce ghosts during this period, the Black Sha Technique once again advanced, gradually transforming from Green Xuan Sha to Ink Spirit Devourer.

However, in order to completely upgrade to Ink Spirit Devourer, Zheng Yi needed to refine nine hundred and ninety-nine vengeful spirits and fierce ghosts or the divine souls of cultivators.

If using the souls of living people for cultivation, the quantity would need to be multiplied by ten.

Although this demonic technique had immense potential and simple cultivation methods, the resulting karma and sins were not to be taken lightly. It was not something ordinary cultivators could bear, which was why many practitioners would switch to other techniques midway. Very few people could cultivate it to the highest level.

If it weren't for Zheng Yi being in the doomsday world, he probably wouldn't have chosen to cultivate this demonic technique.

After all, while strength was important, one's life was also important. He didn't want to be backlashed by karma and die a painful death.

The entire ghost cave was cleansed by Zheng Yi, and all the vengeful spirits and fierce ghosts were completely annihilated, becoming the materials for Zheng Yi's cultivation and providing nourishment for the advancement of the Black Sha Technique.

Without cultivation resources, he had to stop this closed-door cultivation session.

However, the gains were quite fruitful. Mo Ling Sha had transformed one-third of its power, greatly increasing its strength. At this time, Zheng Yi's cultivation had also reached the high-level of the fifth layer of Qi Refining.

Zheng Yi was ready to continue sweeping the surrounding resented spirits and fierce ghosts.

By just devouring a few more demon caves and breaking through another layer of Qi Refining, it was not impossible.

Unfortunately, Zheng Yi had to interrupt his cultivation because the material of the Soul-Capturing Banner could no longer support the ghosts nurtured inside.

This was because, along with Zheng Yi's battles, especially in the doomsday world, the power of devouring the souls of ghosts in large quantities, the main soul of the Soul-Capturing Banner had also reached the mid-level of the Blood Robe realm, and there were also many at the seventh layer of Qi Refining.

As the Soul-Capturing Banner was Zheng Yi's Law Weapon during the Qi Refining period, it had not undergone a second refinement, and the material used could not withstand the impact of the Blood Robe Ghost and the fierce ghost soldiers' realm. Cracks had begun to appear on the Soul-Capturing Banner.

This was like an air cylinder that could only hold 100 liters of air, but was forced to contain 2000 liters of air, resulting in the cylinder exploding.

The situation with the Soul-Capturing Banner was similar.

After hastily ending his cultivation in the doomsday world, Zheng Yi hurried back to the Dayi Immortal Domain and directly summoned Qi Lin to inquire about upgrading the material of the Soul-Capturing Banner.

As a subordinate and the most loyal lackey, Qi Lin deeply understood that everything he currently possessed came from Zheng Yi, and his future prosperity and wealth depended on Zheng Yi's favor.

It could be said that the interests of the two were firmly tied together.

Although Qi Lin's cultivation aptitude was not great, and he was not young anymore, he was the most knowledgeable about human affairs and knew how to get along with people. This was also the reason why Zheng Yi dared to use him with peace of mind.

Qi Lin had long entered a mode where he naturally knew what his superior needed the most and what matters were most urgent.

So when Zheng Yi asked, he almost instinctively gave an accurate answer.

Aside from the mines, the Qi family also had some shop profits. In addition, under Zheng Yi's leadership, they had divided into more than ten commercial caravans, increasing the business of fierce ghost soul stones.

With the continuous increase in the number of soul stones provided by Zheng Yi, the Qi family's caravans had expanded to farther regions, greatly increasing their ability to acquire wealth.

These caravans were not only Zheng Yi's money-making trees but also responsible for providing the information Zheng Yi wanted. The previous underground auction of the Blood Gourd in the Ghost City was obtained through them.

The subsequent tasks arranged by Zheng Yi were to collect materials for upgrading the Soul-Capturing Banner at all costs.

Money can make the ghost grind.

While the caravans expanded in all directions, the caravan managers naturally attached great importance to the tasks arranged by Zheng Yi. They eagerly gathered information and promised to purchase several of the most precious materials at a high price.

With unique sources of information and efficient capital operation, in about half a month, several caravans had obtained all the materials needed to upgrade the Soul-Capturing Banner as requested by Zheng Yi.

The efficiency was so high that it amazed Zheng Yi.

Faced with Zheng Yi's sincere praise, Qi Lin, who was now nominally the head of the entire Qi family, quickly stated that it was just a habit of a businessman.

Being able to solve the worries for his superior was his greatest value.
