Chapter 522 The First Rise of the Soul

However, the Puppet Heart still needs some modifications.

It only absorbs and stores natural energy, without converting it into chakra.

This function should be easy to implement.

Li Yao immediately informed the Wind Release clones, instructing them to arrange for shadow clones to conduct research.

"Besides collecting natural energy to improve analytical efficiency, we can also consider geographical factors..."

"No, it should be starting from all regions!"

"That's right..."

Li Yao and his shadow clone's thoughts diverged, constantly coming up with ideas.

The basic mantras in natural energy are definitely related to the natural environment.

In the desert, the basic incantations of natural energy are more likely to be related to dryness, heat, wind, and sand, or more obvious and easier to analyze and perceive.

Similarly, in volcanic regions, basic spells such as fire, magma, and heat will be easier to decipher.

If you are analyzing these basic mantras related to environmental changes, it is easier to interpret them by sensing natural energy in the corresponding environment.

Unfortunately, space and time are everywhere.

However, precisely because they are ubiquitous, it can also be said that, regardless of the environment, the basic spells of space-time will not change much.

Therefore, as long as the same basic mantra is deciphered from the natural energy collected in different environments, the probability of deciphering the basic mantra of spacetime can actually be increased.

However, collecting natural energy from various environments across the entire Ninja World planet is a massive undertaking.

But no matter how big the project was, Li Yao had to do it.

Where is this puppet heart that collects natural energy placed?

Place it underground?

No.

Li Yao shook his head.

There are white monsters underground.

Li Yao didn't want Hei Jue to know, or even anyone else to know.

Li Yao didn't want anyone to know about his research on the fundamental incantations of spacetime.

In this way, the Puppet Heart can only be placed in the sky, and high in the sky at that, like satellites scattered throughout the entire ninja world.

At the same time, the puppet heart must be shielded from being seen or sensed to prevent it from being seen or sensed.

Improve as you think.

Li Yao and his shadow clone continued their brainstorming session until late into the night.

Li Yao's head was spinning.

However, the result is encouraging. The direction for improving space-time ninjutsu has been found, and it seems very reliable. Perhaps mastering true space-time chakra is not a dream, but a very real possibility.

"It's up to you now!"

Li Yao patted his shadow clone on the shoulder, then teleported back to his bed at Biwa Lake.

With a direction established, the task of putting in the effort was left to the shadow clones, while Li Yao was responsible for continuing to torment the Third Generation.

Snapped!

With a snap of his fingers, Li Yao caused a protective barrier to rise within the room.

"Li Yao!!!"

Biwako, who had long since regained her memories, suddenly turned around and saw Li Yao embracing her, instantly screaming in alarm.

But all they could do was scream in terror; there was nothing else they could do.

Her body was constantly under Li Yao's five senses manipulation technique.

Li Yao is now becoming increasingly proficient in using ninjutsu that manipulates the five senses.

"What did you do to Hiruzen?"

"You bastard..."

"Ah...no!"

While cursing Li Yao, Biwako put aside her pride and faced the challenge head-on.

Li Yao lay down with his hands behind his head, laughing, "Your husband and Danzo are probably having a tug-of-war right now, just like you are?"

"Tug-of-war?"

Biwako was taken aback for a moment, but quickly realized what Li Yao meant by tug-of-war, and then she was stunned again.

"Hiruzen and Danzo? The two of them... are having a tug-of-war? How?"

Biwako looked puzzled, but Li Yao laughed and said, "I'll take you to see how they have a tug-of-war sometime."

"Damn it... Ah..." Biwako wanted to curse Li Yao, but she couldn't control her body's instincts. She could only fear Li Yao's power and submit to him.

However, Biwako breathed a sigh of relief.

Although it's obvious without even thinking that the tug-of-war Li Yao mentioned was definitely not a good thing, at least it proves that Hiruzen is still alive.

That's enough for Lake Biwa.

But when she thought about her current state, she felt that perhaps it would be better if Hiruzen were dead, and that death would bring her relief.

"Hurry up," Li Yao suddenly said.

"..." Biwako's expression froze for a moment, then she was too lazy to scold him and lowered her head to clean up for Li Yao.

"Hmm!" Li Yao's expression suddenly changed, and he instantly opened Biwa Lake, placed his hand on her stomach, and sent a stream of Wood Release chakra into the place where Biwa Lake was nurturing the child.

There, a faint fluctuation of chakra was born.

That was Li Yao's chakra fluctuation.

However, it was not under Li Yao's control.

Li Yao was very familiar with this situation.

Back when his eldest son's wife, Sarutobi Ayase, was pregnant with his son, there was also Li Yao's chakra fluctuation within her.

Therefore, the old woman from Biwa Lake became pregnant with Li Yao's son.

But this was not the reason why Li Yao's expression suddenly changed.

Because getting Biwa Lake pregnant was Li Yao's plan all along.

What startled Li Yao was that he sensed that the life force gestating within Biwa Lake not only had his chakra fluctuations but also other fluctuations.

This fluctuation was so subtle that Li Yao wouldn't have noticed it if Biwako hadn't received his chakra at that moment and sensed it at close range through merging with his chakra.

"What kind of fluctuation was that?"

Li Yao frowned in thought. It didn't seem like a chakra fluctuation, nor a mental fluctuation. Instead... it seemed more like a fluctuation of will!

Fluctuations in will?

A newly formed fertilized egg?

That can't be right, can it?

Li Yao was somewhat uncertain.

Willpower is generally born only in intelligent souls.

What kind of wisdom does a fertilized egg possess?

Without wisdom, it would be impossible for will to exist.

"Could it be a soul fluctuation?"

Li Yao suddenly realized something, and his eyes lit up as he felt that his guess might be correct.

At this point, the fertilized egg inside Biwako's body could no longer be called a fertilized egg, but rather an independent embryonic cell.

Because Li Yao's chakra fluctuations inside were no longer under his control.

Although the individual embryonic cells have not yet developed into a complete human life form, nor have they given rise to a faint consciousness.

But without a doubt, this single embryonic cell is already an independent living entity.

Since it is an independent living entity, it naturally has a soul.

However, at this stage, the soul is likely still unformed, much like an embryonic cell that has not yet developed into a fetus.

Therefore, it can only exist as a slight fluctuation.

Therefore, this faint fluctuation should be the fluctuation of a newly born soul.

"Perhaps... we can find a way to enhance our soul power from this nascent soul fluctuation!"

Li Yao suddenly had an idea, and his interest was greatly piqued, so he continued to sense it.

Since ancient times, every life has had two pivotal moments.

One is the birth of life.

One is life and death.

The same applies to the soul.

But no matter who it is, they will only focus on the changes that occur when the soul dies.

The Sage of Six Paths created a Pure Land to absorb the souls of the dead and the power left behind by their dissipation, which he used to enhance his own soul power.

This is the rebirth of the Sage of Six Paths forged through death.
