We're practicing all martial arts, so why did you switch to easy mode?

"???"

Su Chen was filled with questions and looked at the old man with a puzzled expression.

The old man knew what Su Chen was thinking, so he smiled and said, "You heard me right, I want to go back to your world with you."

"Why?"

Su Chen asked back.

The old man did not hide anything and explained, "Because I have reached the limit in the world of Gu Masters, and if I want to go further, I can only leave. As you can see, I am relatively young, so I naturally do not want to stay in the world of Gu Masters until I die. Leaving here will allow me to appreciate higher scenery, experience a more carefree life, and help me become stronger."

You can tell that although the old man is old, he has a very young mindset.

"How old are you?" Su Chen felt he was being a bit presumptuous, but he couldn't help asking anyway.

He stared at the old man, whose head was full of white hair and who did not look young at all.

Moreover, the old man exuded an aura of decline.

"It is over 80,000 years old."

The old man pondered for a moment before replying.

Su Chen fell silent upon hearing this. Gu Immortals were essentially equivalent to Martial Immortals. According to Su Chen's understanding, the lifespan of a Martial Immortal should be around 100,000 years. The old man was already over 80,000 years old, so he had at most 20,000 years left to live.

"I still have a question," Su Chen asked after a moment of silence.

The old man smiled and said, "You want to ask me why I don't leave the world of Gu Masters myself, right?"

Su Chen nodded.

Martial Immortal has the strength to break through the boundary.

In other words, if the old man wanted to leave, no one could stop him.

According to the old man, since he wanted to go to other worlds to broaden his horizons, he could leave at any time.

In any case, the void wouldn't hinder him in any way.

There was absolutely no need for him to specifically take the old man to the Ten Directions World.

Without understanding the old man's purpose, Su Chen naturally wouldn't agree to his request.

He worried that if the old man had ulterior motives, his decision might bring disaster to the entire world.

Although he knew that there were Martial Immortals in the Ten Directions World, Su Chen was still extremely cautious.

Seeing Su Chen's unpredictable expression, the old man knew that Su Chen wouldn't agree unless he gave him a reasonable explanation.

So he said, "You're thinking too simply. Traveling through the world isn't that easy."

Even a celestial demon needs to know the location of other worlds in order to mark them and travel between them; otherwise, it is impossible to enter other worlds.

My strength has reached the Gu Immortal realm, and I do have the ability to leave the Gu Master world. However, the problem is that I cannot find the ability to enter other worlds.

look. "

As he spoke, the old man waved his hand, and ripples immediately spread through the air.

Amidst the ripples, a profound scene unfolds: the starry sky.

"This is the starry sky outside the world of Gu Masters. The starry sky is vast and boundless, and most of it is lifeless. How difficult it is to find a world with life."

I have traveled for a thousand years, but I still haven't found a world with life.

Finally, left with no other choice, he had to return to the world of Gu Masters.

His tone was full of helplessness. A thousand years of searching had come to nothing, and one can only imagine the pain he felt.

He paused for a moment, then continued, "You should know that before you appeared, there was actually someone else who unintentionally came to the world of Gu Masters."

"Mm." Su Chen nodded.

"At the time, I was still out there gaining experience, so I didn't know the situation. By the time I found out, it was too late."

So I deliberately set up a plan at the Kitagawa family's residence, hoping to wait for the next person to appear.

Your appearance confirms my suspicions.

That is the world of Gu Masters, which has already been marked by other worlds.

Although it's unknown how the other party marked it, the fact that two people in a row were able to enter the Gu Master world is enough to prove the correctness of this explanation.

The old man continued.

"Then why don't you look for a marker and use it to leave?" Su Chen asked again.

The old man shook his head: "I searched, but unfortunately I couldn't find it. If I'm not mistaken, it's almost impossible for me to find it."

"Then how can you be sure I can find it?" Su Chen was still puzzled; he had a feeling that the old man was hiding something.

Sure enough, the old man said meaningfully, "If you can come in, you can naturally go out."

"This……"

Su Chen understood the old man's meaning. "You mean, only those who come in from the outside can leave, while those who are inside cannot leave, even if you have already broken through to the Gu Immortal realm?"

The old man didn't answer, but his expression told Su Chen that his guess was very likely true.

"How about it? You take me out, and in return, I can help you fuse two kinds of immortal energy."

Seeing that Su Chen did not answer, the old man spoke up.

He believed that Su Chen, who had experienced the wonders of Yin-Yang Immortal Qi, would certainly not be able to refuse his suggestion.

To be able to receive the baptism of immortal energy before even reaching the fairyland is an incredible opportunity.

I believe no one could refuse it.

He knew this all too well.

Although Su Chen's identity is unknown, no matter how noble Su Chen's identity is, or even if there are cultivators in his clan who are at the Immortal Realm, it is impossible to infuse him with immortal energy for cultivation at all times.

Su Chen currently possesses two types of immortal energy; once they merge, they will become true immortal energy.

Immortal aura is one of the most fundamental differences between ordinary cultivators and immortal cultivators.

If Su Chen could obtain the nourishment of immortal energy at the level of a Nine-Turn Gu Master, it would greatly benefit his future cultivation path.

Just as the old man had thought, Su Chen was indeed tempted.

However, he did not agree immediately, but pondered the consequences of doing so.

As he pondered, a subtle feeling arose within him, a feeling that allowed him to glimpse a corner of the future.

They are better able to know the consequences of a certain behavior.

In this state of mind, Su Chen did not sense any malice from the old man, indicating that the other party might not have any ill intentions.

After careful consideration, Su Chen finally agreed.

“Alright, but there’s something I must tell you beforehand, senior. I’m not sure if this Gu worm can take me back. Even if it can, I can’t guarantee that it will bring you back. But please rest assured, senior, I will do my best.” Su Chen didn’t dare to make a guarantee, so he reminded him in advance.

The old man didn't seem to mind and smiled, "Well, let's leave it to fate. If it really doesn't work out, I won't blame you."

"Shall we begin then?" Su Chen felt relieved, his tone becoming expectant.

The old man was also very eager; he had waited so long and was finally able to leave this dilapidated cage.

He said, "Calm your mind and guard your spirit. I will guide you. Follow my guidance and you will be able to merge!"

Su Chen did not reply. He closed his eyes and began to control the Yin and Yang immortal energies within his body as the old man had instructed.

In an instant, Yin Immortal Qi flowed into Su Chen's body from his primordial spirit and began to merge with Yang Immortal Qi.

Seeing this, the old man spread his hands, and a burst of immortal energy shot out from his body and landed on Su Chen.

With the guidance of this immortal energy, Su Chen became more adept at controlling it.

Guided by this immortal energy, the Yin and Yang energies began to slowly merge.

At first, Su Chen carefully mobilized some of the Yin-Yang Immortal Qi to fuse them.

After discovering that this immortal energy could indeed help with fusion, Su Chen gradually increased the amount of Yin-Yang immortal energy.

"Don't worry, just focus on the integration, I'll be watching."

Perhaps seeing Su Chen's excessive caution, the old man's voice rang in Su Chen's ears. "How long will it take to fully fuse like this?"

Upon hearing the old man's words, Su Chen did not hesitate and released all the immortal energy within his primordial spirit and body.

In an instant, the entire cave was filled with Su Chen's two kinds of immortal energy.

Among these two types of celestial energy, there is a purer one, which flows between them like a yin-yang symbol.

It continuously plays the role of bridging and connecting, promoting the fusion of the two kinds of celestial energy.

Seeing this, Duan Tiandao immediately said to Wen Qingya beside him, "Quickly sit down and absorb it."

This is celestial energy.

Even absorbing just a little bit would be of immense benefit to them.

Wen Qingya also knew the benefits of immortal energy. Upon hearing Duan Tiandao's words, she immediately sat cross-legged and began to absorb it.

Soon, the entire cave became completely silent.

Time passed indefinitely. As more and more Yin and Yang immortal energies merged, Su Chen's primordial spirit and physical body were affected.

He felt as if his primordial spirit and physical body were about to merge together.

This immediately made him want to resist, but as soon as he moved, he heard the old man's voice: "Don't stop it, let nature take its course. This is tempering your body and primordial spirit. When they are tempered to their limit, they will fuse together. This is the path to immortality!"

Upon hearing this, Su Chen stopped interfering and allowed the two to merge.

Before long, the Yin and Yang immortal energies within Su Chen's body completely merged, giving birth to true immortal energy.

After the old man realized this, he took the initiative to withdraw his immortal energy from Su Chen's body.

The next step of the integration will depend on Su Chen himself.

Just as he said, this is the path to immortality.

If the fusion is successful, Su Chen will likely break through to a true immortal realm with the help of immortal energy.

But if it fails, the consequences will be unimaginable.

He indeed had no ill intentions towards Su Chen. When he noticed the change in Su Chen, he took the initiative to protect Su Chen.

He was even worried that Duan Tian Dao and Wen Qing Ya would affect Su Chen, so he took the initiative to isolate the two of them from absorbing immortal energy.

"He cannot be disturbed in the slightest now."

Looking at Duan Tiandao and Wen Qingya, who had just awakened from their cultivation, the old man said something indifferently.

Immediately, his gaze turned to the Heaven-Severing Blade, and he clicked his tongue in amazement.

The old man's gaze made Duan Tian Dao feel uneasy, and he couldn't help but ask, "Old man, why are you looking at me like that?"

"You are quite peculiar," the old man said solemnly.

There's nothing special about this knife. Even if it were to have a soul, a primordial spirit, and the wisdom of humans, it would still be nothing special to him. After all, he had seen many Gu worms, some of which possessed human-like qualities, and some were even stranger than the Heaven-Severing Blade.

Strangely, he actually saw in this knife the potential that only immortals could possess.

This is a bit incredible.

For humans, cultivating to become immortals is incredibly difficult.

Other living beings are even inferior to humans. If they were not incredibly lucky and favored by the heavens, they would probably have a very short time to cultivate into immortals.

But this knife happens to possess the potential to become an immortal.

Both his sword and his primordial spirit are already transforming in this direction.

What's even more peculiar is that Duan Tian Dao is now at the ninth level of perfection, and can actually perform spatial teleportation, something only a Gu Immortal could do.

This can no longer be described as merely bizarre.

"Although I don't know why, I suppose you wouldn't know either if I asked you."

The old man was talking to himself.

Duan Tiandao was speechless after hearing this: "How would I know if you didn't tell me?"

Fortunately, the old man didn't say, "Even if I told you, you wouldn't know." He smiled and asked, "Then can you tell me why you can absorb spatial Gu worms?"

"Uh." Duan Tian Dao was speechless.

He didn't know why either.

The old man, having anticipated this, continued, "Little Knife, why don't you take a look at it for me?"

Don't call me Little Knife!

Upon hearing the other party call him Little Knife, Broken Sky Knife immediately became dissatisfied, but the old man's next words instantly filled him with terror.

He shook his head repeatedly: "No, I refuse."

However, his words lacked confidence.

After all, he knew the old man's strength; even Su Chen was no match for him, let alone him.

"I'll give you a spatial-type Gu worm to help you refine it, is that alright?"

The old man patiently guided him, and with a flick of his wrist, he produced over a hundred spatial-type Gu worms.

The levels vary, but they are all above the seventh rank.

Duan Tiandao's eyes nearly popped out of their sockets as he watched. He stroked his chin, and his almost tangible primordial spirit began to ponder.

After thinking for a long time, he gritted his teeth and said, "I'll do it! But if I find anything wrong, I'll give up. Don't blame me then."

"No problem." The old man chuckled.

Upon hearing this laughter, Duan Tiandao couldn't help but shiver, but he still didn't back down.

The old man flicked his arm, sending the Gu worms to the Broken Sky Blade, and then observed the changes in the Broken Sky Blade.

Without any hesitation, the Heaven-Slaying Blade took everything into its possession and began to absorb it.

"Amazing!"

After observing for a long time, the old man still couldn't figure out what was going on, only feeling that the Heaven-Severing Blade was very special.

I just don't know why he was able to refine spatial Gu worms so easily.

"If spatial Gu worms can be refined, what about temporal Gu worms?"

The old man had a sudden inspiration, so he took out the few time-related Gu worms he had and gave them to the Broken Sky Blade to absorb.

To his surprise, the Heaven-Severing Blade could also absorb it.

However, the Heaven-Severing Blade cannot absorb other types of Gu worms.

"Try this."

Witnessing the Heaven-Slaying Blade simultaneously absorbing both space- and time-related Gu worms, the old man felt he was still missing a crucial opportunity.

Then he took out another Gu worm from his bosom.

This was a Gu worm that even he couldn't control, but judging from the power of time flowing on it, it was definitely an extraordinary Gu worm.

The Heaven-Slaying Blade didn't hold back and quickly absorbed the energy.

"not good!"

It's unclear whether it's due to this Gu worm or because the Heaven-Slaying Blade absorbed too many time and space-type Gu worms.

This caused the entire cave to be filled with the power of time and space.

These two forces, under the influence of the immortal energy, became exceptionally violent.

At the same time, the celestial energy becomes incredibly sharp due to the presence of these two forces.

Upon realizing the situation, the old man immediately protected Wen Qingya and the cave to prevent them from being affected.

Fortunately, Su Chen was not affected.

This situation lasted for several hours before it subsided.

Su Chen was the first to awaken from his cultivation. Sensing the two terrifying powers, he couldn't help but look at the old man: "What happened?" (End of this chapter)
