Lu Yin sighed in amazement. As expected of the strongest power in the Northern Region, Ku Ji had relied on his own strength to reach the peak of Ku Er. His aura was not any weaker than Grand Sovereign Lan Ye's, and there was a sense of invincibility.
Ku Ji cultivated a mental cultivation method and had a calm mind, but once he attacked, it was earth-shattering.
If Ku Ji fought against Grand Sovereign Lan Ye, Lu Yin was certain that the latter would not be his match.
Of all the peak Ku Er powerhouses that Lu Yin had seen, Ku Ji was ranked at the top. He was comparable to Ying Mei, who had not used the Spring and Autumn Simplified Manual, and his mental state far surpassed hers.
"Mister Lu, be careful," Ku Ji growled, and the nine abysses rumbled together. Suddenly, darkness enveloped them as the abyss swallowed them.
The void around Lu Yin collapsed, and he was drowned by the abyss.
This was Ku Ji's true fighting style. He used the abyss to swallow the enemy, and even a peak Ku Er powerhouse would find it difficult to escape. The world had turned into an abyss that swallowed all power.
Mental cultivation methods originated from the spiritual universe. The higher one's mental state, the stronger their mental cultivation method, and the deeper the abyss.
In the past, the Ninth Firmament had invaded the spiritual universe, and more than one expert had been swallowed by the abyss. Legend had it that even an Eternal Realm powerhouse had almost been swallowed by the abyss.
That was something that only an expert with an infinitely powerful mental cultivation method could do.
A person's strength was limited, but their mind was limitless.
The higher one's mental state, the deeper the abyss.
Ku Ji and Ku Ji were on completely different levels, and it was not as simple as the abyss.
It was a transformation of one's mental state.
It was like the difference between the Seven Great Mulberry Skies and the Imperial Mulberry Skies.
Lu Yin looked around and saw that he had fallen into the abyss and was constantly being swallowed. He felt his consciousness, thoughts, power, and everything else being swallowed up. All he could see was the abyss and Ku Ji.
Ku Ji was magnified countless times, replacing the sky and the universe.
It was difficult for Lu Yin to escape.
It blotted out the sky.
In the darkness, Ku Ji blossomed with a dazzling light that illuminated everything.
Lu Yin experienced the terror of mental cultivation methods. Fantasies were fake and could only scare people, but mental cultivation methods were real and could achieve anything.
However, fantasies could be unlimited, but mental cultivation methods followed one's mental state.
Lu Yin praised, "Ku Ji's mental cultivation method is terrifying. It has endless possibilities."
Ku Ji's expression changed. How could he speak so easily?
How could his voice break through the abyss?
Everything should be swallowed by the abyss, but this person?
Lu Yin looked up at Ku Ji, "Senior, I'll be leaving now."
He then took a step forward under Ku Ji's incredulous gaze. In front of him, the earth, the breeze, the blue sky, the white clouds, and the darkness that had originally enveloped the Northern Region all converged into the abyss. Behind him was the abyss, but it actually only covered a small area. It wasn't very large, and Lu Yin stepped through it as easily as taking a normal step forward.
However, this step left Ku Ji in disbelief.
All the cultivators of the Bitter Abyss who saw this scene were in disbelief.
Since when was it so easy to walk out of the abyss?
It was just a single step. Was it that simple?
Lu Yin turned around and smiled at Ku Ji.
Ku Ji stared at Lu Yin in a daze, and then a bitter expression appeared on his face as the abyss dissipated. He slowly descended to stand in front of Lu Yin and exclaimed, "Mister Lu, you're invincible, and your state of mind is perfect. I admire you."
Lu Yin shook his head. "It's too early to say that I've reached perfection. If I can reach perfection, then I won't be stepping out of the abyss, but rather, into eternal life."
Ku Ji laughed. "It's just a single step. The abyss isn't an obstacle to Mister at all. You've truly taught our Bitter Abyss a lesson."
Lu Yin praised, "The Bitter Abyss Cultivation Method has limitless possibilities. Don't underestimate it just because it's a single step. 99% of the cultivators in the world are stumped by it, and of the remaining 10%, 99% have to rely on luck or perseverance. There aren't many who can truly take this step."
Ku Ji replied, "Mister, there's no need to console us. The hearts of the cultivators of the Bitter Abyss aren't that weak. Of course we know that. It's just that Mister has shocked us too much."
Ku Ji walked over and looked at Lu Yin in disbelief. "Could it be that Mister has already reached eternal life?"
"Ku Ji, could it be that only with eternal life can one take that step?
You overestimate our Bitter Abyss and underestimate Mister, "Ku Ji reprimanded.
Ku Ji quickly apologized.
Lu Yin smiled. "The Bitter Abyss Cultivation Method is admirable. Senior Ku Ji, I heard that the Bitter Abyss doesn't restrict people from learning it. Is that true?"
Ku Ji replied, "Of course. Does Mister want to learn it?"
Lu Yin nodded. "Yes."
"Then you'll have to wait for some time. The Bitter Abyss Cultivation Method can't be learned here."
"The mind universe?" Lu Yin asked.
Ku Ji nodded. "Only by seeing the Astral Abyss in the mind universe can one learn the cultivation method. It can increase one's strength, so it's normal for Mister to want to learn it. It's a pity that very few have been able to learn it over the years."
"Seeing the Astral Abyss only gives one a chance to learn it."
"Every hundred years, the Bitter Abyss uses the Ninth Night Pillar to bring a group of people to the mind universe. There are many experts among them. If Mister wants to learn it, you can contact Mister the next time you set off."
Lu Yin hadn't expected that he would have to wait a few decades, but that would pass quickly. "Thank you, Senior Ku Ji."
He really wanted to learn the cultivation method, but there were only a few people in the Nine-Firmaments Universe who had managed to learn it over the years. Many of them were extremely talented, and he didn't think that his talent would surpass everyone else's. It was impossible for him to find another way to learn it, so he could only follow the Bitter Abyss' method.
Furthermore, Ku Deng was also in the mind universe.
Ku Deng was the true number one expert of the Bitter Abyss, the Bitter Abyss Master. Lu Yin was very curious about this person's strength.
Although he couldn't learn the cultivation method, Lu Yin still chose to stay in the Bitter Abyss. The Bitter Abyss Cultivation Method was a way to cultivate the power of the abyss, and there were different ways to cultivate one's mental state. For example, Ku Cheng had been climbing the Mother Tree, which was the method most of the Bitter Abyss' cultivators chose.
There were also people who created their own trials.
There were also people like Lu Yin, who wandered the world and observed its various forms.
There were different ways to cultivate one's mental state.
Lu Yin needed to cultivate his mental state, and he told Ku Cheng and the other Bitter Abyss cultivators about what he had done before. Many of the Bitter Abyss cultivators' eyes lit up, and they said that they wanted to try it out.
Mortal cities were the best places to cultivate one's mental state. Ordinary people only lived for a hundred years, and during that time, they would experience birth, old age, sickness, and death. Some ordinary people's mental state far surpassed that of cultivators, and this wasn't something that could be compensated for by living longer.
Once one's mental state broke through, it would undergo a qualitative change.
"What?
You're in the Bitter Abyss?
You didn't go to Cang Tian City to look for Second Sis? "Lu Siyu exclaimed.
Lu Yin replied, "I was, but there was an accident along the way. I happened to run into people from the Bitter Abyss, so I stayed."
"What about Second Sis?"
"Is she in a hurry?"
"Not really, but she gave a condition to many people. Whoever can fulfill it can marry her. Once someone fulfills it, you'll fail. You know the consequences." Lu Siyu reminded him.
Lu Yin smiled, "Are you worried about me?"
Lu Siyu bared her teeth, "No, even if you fail, you'll have to wait until the last condition is fulfilled. It's best to let you fulfill all six conditions for free."
Lu Yin said, "Everything depends on fate. Teal Lotus Emperor is particular about fate, and so am I. How can you be sure that no one fulfills your Second Sis's conditions on my way to Cang Tian City?
Or if your Second Sis fancies a talented young man, he'll be able to fulfill it. "
"My Second Sis isn't that shallow."
"But she'll get married eventually."
"What, can't bear to?
You haven't even met her yet, but you can't bear to. You're really young. "She paused," Hmph, then when are you going to Cang Tian City? "
Lu Yin looked in the direction of the Mother Tree, "There's no rush. Maybe I'll find something here."
In the Eastern Region, Lu Siyu looked at Huai Si in a daze and thought for a moment before contacting her second sister.
"Sis, will you be going out soon?"
"Where to?"
"Leaving Cang Tian City."
"Aren't you going to wait for Lu Yin?"
"Well, he's in an accident, so he might be late."
"It's okay, I can wait."
"Thank you, Second Sis."
"Hey, Seventh Sis, why are you thanking me?"
Lu Siyu was stunned and quickly ended the call. That's right, what does it have to do with me?
Her face flushed red, and she hurriedly put away her nostalgia.
In the Northern Region, Lu Yin followed Ku Cheng to the Mother Tree.
"Can climbing the Mother Tree really train one's state of mind?"
Ku Cheng said, "For ordinary people, two neighboring cities are extremely far away. Under the premise of knowing the distance, whether to set off or not is the biggest problem."
"This is the transformation of one's state of mind. Some people can take ten years or even a hundred years to walk a path with no end in sight. For us, climbing the Mother Tree as an ordinary person takes a hundred years, a thousand years, or even ten thousand years. One day, we'll reach the top. This is the transformation of one's state of mind."
Lu Yin finally understood. Some people would forever stay in their own little circles and never leave, maintaining their comfort zone. Others would roam the world and experience dangers, so it was only natural that their states of mind were different.
"But how do we climb the Mother Tree as an ordinary person?" Lu Yin was puzzled.
Ku Cheng said, "Mental cultivation method. The abyss can support any power, and it can also seal any power."
Soon, the two arrived at the Mother Tree.
This was the first time Lu Yin had been so close to the Mother Tree.
The Mother Tree's trunk was boundless, and he couldn't see the end.
He raised his hand and placed it on the trunk. An indescribable feeling spread to his heart. It was so familiar and so warm.
This warmth reminded him of the Mother Tree in the Astral Tree.
The Mother Tree had helped humans block the Eternals and became the barrier of the Fifth Mainland in the Origin Space.
Whether it was the Tianyuan Universe or the Empyrean Universe, this tree was called the Mother Tree.
The word "Mother" had a special meaning. It existed, relied, trusted, protected, and originated.
He thought of the sapling.
The Mother Tree in the Astral Tree had Astral Liquid. If he guessed correctly, the Mother Tree also contained the cultivation power of the Empyrean Universe, which was the spirit seed liquid.
Seeing Lu Yin staring at the Mother Tree in a daze, Ku Cheng's gaze changed again. Before, it was respect, admiration, and admiration. Now, there was a sense of closeness.
The people of the Bitter Abyss were very close to the Mother Tree.
Many people in the Empyrean Universe only treated the Mother Tree as a plant. It was common knowledge, and they never considered the significance of the Mother Tree's existence. The people of the Bitter Abyss were different. They climbed the Mother Tree all year round, and their understanding of it surpassed most people. They caressed the Mother Tree's trunk and slept on its branches when they were tired. The Mother Tree wasn't just a cultivation aid, but also an instinctive dependence.
Thus, the people of the Bitter Abyss would protect the Mother Tree.
