I can push my cultivation progress to the end

Buzz—

With a thought from Li Hai, a message suddenly unfolded in his vision:

"Do you want to upgrade 《Northern Dipper Reversal Life Profound Art》 from Level Zero to Level Three—Yes/No?"

"Huh? It really works!"

Overjoyed, Li Hai immediately chose "Yes".

Immediately, he vaguely felt himself falling into the deepest part of the boundless sea, surrounded by cold and icy salty seawater.

These seawater were almost like living creatures, with streams and bundles carrying malicious intent, constantly rushing into Li Hai's eyes, ears, mouth, and nose, as if trying to completely block his breathing and suffocate him to death.

But at the same time, there were hundreds of streams of clear slurry, even colder and more frigid than this deep-sea water, that suddenly appeared around Li Hai and instantly drilled into all the pores of his body.

Instantly, these icy slurry permeated and penetrated all of Li Hai's internal organs, meridians, bones, and even more subtle levels.

While penetrating, these slurry also thoroughly transformed every part of his body from the inside out to a very deep level.

Whoosh—

As if having experienced a cycle of reincarnation, Li Hai felt that his body and soul had all turned into fish in an instant, turning into a giant Kun swimming in the boundless ocean and galloping in the abyss of ten thousand fathoms.

He was no longer afraid of the cold and darkness of the deep sea, but instead felt that the vast ocean was so kind, full of endless vitality, and this vitality was constantly nourishing him, constantly strengthening him, making him forever unharmed, invincible, and fearless.

However, Li Hai knew that all of this was just an illusion.

There was no sea at all, and he had not turned into a Northern Dipper Kun.

According to the records in the 《Northern Dipper》 technique, this was just a normal phenomenon produced when practicing demonic martial arts, caused by the influence of the memory fragments in the demon blood.

After the completion of the practice, it will naturally fade away.

Sure enough, the next moment, all kinds of illusions suddenly receded and disappeared.

At the same time, Li Hai slowly opened his eyes.

And his pupils turned into azure blue, like the sea.

"The various realms of demonic martial arts are divided into nurturing demon seeds, cultivating seeds into fetuses, fetal transformation and changing souls, stirring souls and reforming bodies, and tempering bodies into demons, from low to high."

Li Hai grinned, "Hahaha, I have crossed into the fifth realm of demonic martial arts in one step—tempering the body into a demon. The system is really powerful, no demon blood or secret medicine is needed."

Now, his appearance has not changed much, only his eyes have turned azure blue.

But the organs, internal organs, and even the meridians, bones, and even blood in his body have been completely transformed, becoming far beyond ordinary people.

At the same time, this also added two new entries to him—Self-Healing Level 3 and Aquatic Level 2.

"My physical strength… has increased several times!"

Li Hai slowly raised his hand, made a knife with his fingers, and slashed down fiercely.

Whoosh—

In an instant, a vacuum air blade visible to the naked eye was slashed out, slashing diagonally towards ten zhang away.

Bang!

The next moment, a stone statue leaning against a ruined wall in the ancient sect ruins more than ten zhang away was decapitated by the vacuum blade.

This move, like the invisible sword energy in martial arts works, actually has no skill or trick to launch, it is purely created by unparalleled power and swiftness.

To put it bluntly, it is a normal attack skill piled up with extremely high values.

Li Hai could do this effect before, but he couldn't do it as easily as he does now, as easy as breathing.

However, in the entry characteristic column of the personal interface, his entries related to physique and strength, such as 【Strengthening Soul】, 【Fingers and Claws】, and 【Brute Force】, are still only Level 3 and have not reached Level 4.

This could not help but make Li Hai guess:

"In this way, the gap between each level of the entry is still quite large, so large that even if my strength has increased several times, it has not reached Level 4."

"Huh?" Li Hai asked suspiciously, "Why?"

"My lord."

Qiu Fangzheng's jaw opened and closed, "Just now, when you were reading the books, I don't know why, but I heard a mysterious sound, that sound told me… that my hatred is gone and my hostility has disappeared, I can… be reincarnated."

After saying this, his skull face suddenly blurred and miraculously transformed into a normal human face with flesh and blood.

"Reincarnation?"

Li Hai looked at Qiu Fangzheng's changes with a stunned expression.

In fact, he did see relevant information about the reincarnation of evil spirits in the warehouse of the Demon Slayer Division's stronghold in Niujiao Town.

But it said that the reincarnation of evil spirits has always been rare in the world, so rare that one may not appear in the entire world in a hundred years.

The reason for this is that the resentment and hatred of evil spirits are extremely difficult to resolve.

Even as time passes and more and more killings occur, their resentment and hatred will become more and more intense, and eventually completely solidify, making it impossible to resolve even a trace.

Unless this ghost was inherently kind in life, and even if he was full of resentment after a tragic death, he would still be kind and never kill indiscriminately.

Otherwise, the so-called reincarnation of evil spirits would just be empty talk.

But now it seems that this is not empty talk.

Because Qiu Fangzheng just happens to meet the description in the information.

He was a kind person in life, so kind that even after being killed by Zhou Ruigen in the deep mountains and turning into an evil spirit, he never obeyed the ferocious nature of ghosts to eat people and harm people, and even kindly sheltered the Zheng Dashan family.

And now Li Hai has helped him avenge his revenge and helped him fulfill his thoughts and worries about his sister Qiu Fanglan, isn't this… equivalent to completing all the prerequisites for the reincarnation of an evil spirit?

After understanding this, Li Hai didn't say much, just sighed and said: "This is indeed a good thing, you can be considered liberated and can be a human again."

"Yes."

Qiu Fangzheng nodded and said, "My lord, you are right, being a human is still better than being a ghost."

While speaking, his figure and ghost body obviously began to blur, and the strong resentment and malice that had been lingering around him also slowly dissipated and disappeared.

Also at this time, Qiu Fangzheng slightly raised his head as if he felt something, and suddenly said again:

"My lord, in the dark, I sensed… that I might be reborn within the Jing Dynasty. If you need me in the future, you can look for me. With your great power, you will definitely be able to find me. At that time, I will also do my best for you!"

Hearing these words, Li Hai couldn't help but fall silent, and then raised his voice and said:

"Don't worry, I will definitely find you, Brother Qiu. You are much older than me, so you don't need to call me 'My lord' anymore. Let's call each other brothers."

Qiu Fangzheng was stunned when he heard this, and then laughed heartily: "Good, good, good! It is my great fortune that I, Qiu Fangzheng, can get to know a heroic figure like Brother Li. If there were wine here, I would have to get drunk with Brother Li for three days!"

Li Hai smiled when he heard this: "Don't worry, when you grow to seven or eight years old and can drink alcohol, I will find you again to get drunk."

"Hahaha, good."

Qiu Fangzheng laughed, "Then this drink will be scheduled for my next life, goodbye, Brother Li."

After saying that, he vanished into thin air and completely disappeared in this underground cave.

Leaving Li Hai alone standing with his hands behind his back, not knowing what he was thinking.
