The primordial era began with the Upper Cave Man.

In fact, this primordial spirit brain plus is already somewhat insufficient for cultivating the Taiyi realm.

Therefore, this deductive method needs to be upgraded, otherwise the path of cultivation will be greatly delayed.

As for how to upgrade and in which direction, Luo Zu now has some plans.

First, it strengthens the primordial spirit brain to a deeper level, potentially becoming a plus-max. Second, it completely alters its structure, upgrading it from a primordial spirit brain to a Dao fruit brain.

This is an upgrade in organizational structure, not an upgrade in the basic materials that make up the brain, so the difference is quite significant.

So, what should Luo Zu choose?

As for merging the two and conquering the world together, that would be difficult, as sometimes this organizational structure cannot be compatible with different materials.

However, the Primordial Spirit Brain does have considerable development potential. After all, the Primordial Spirit Brain was created based on the Primordial Spirit of Luo Zu. Now, Luo Zu's Primordial Spirit has progressed to the state of an indestructible Primordial Spirit. After merging with the indestructible spiritual light, its power is not only limited to the "indestructible" characteristic, but can also carry a larger amount of higher quality calculation power.

Therefore, if the primordial spirit and brain were to imitate this immortal primordial spirit, they should be able to make great progress.

However, there are quite a few difficulties involved. After all, the formation of the immortal primordial spirit relies heavily on the immortal spiritual light, so it is indeed quite difficult to refine the brain of the immortal primordial spirit.

Luo Zu began to deduce these changes a hundred years ago, intending to analyze the undying spiritual light.

After deciphering the mysteries within, the undying primordial spirit brain was easily created.

The undying spiritual light is truly mysterious. It was born from the spirit and the heart of the Dao, and later it was combined with the wondrous principles of the purest existence in the world, the Great Dao, and finally became such a wisp of undying spiritual light.

Therefore, this undying spiritual light is the ultimate principle of the universe, corresponding to the "existence" of the universe. As such, it is really difficult to annihilate Taiyi, which has condensed the undying spiritual light, unless it is destroyed by the opposite destruction, the principle of the Dao cultivated by the Great Dao of Nothingness. Only in this way can the undying spiritual light be destroyed, and Taiyi be destroyed along with it.

Because of this, Luo Zu spread his thoughts: the fall of Ancestor Hongyun back then was probably caused by being killed by the two innate top-grade spiritual treasures and magic swords that accompanied Ancestor Minghe, which destroyed his indestructible spiritual light and ultimately left him with no chance of rebirth. He could only live another life by borrowing a bit of remnant spirit, and even after he came back to life, he would only be Yun Zhongzi and no longer Hongyun.

In short, Taiyi is not invincible, but it is difficult to completely eliminate. How many great supernatural beings in the world cultivate their own Dao fruit through the great Dao of destruction and the end of Dharma?

Luo Zu stopped thinking and did not let his thoughts wander out. Although this wisp of thought lasted for less than a moment, for an existence like him, countless thoughts and achievements were generated in that moment.

The entire process of the creation and evolution of this grotto-heaven can be recalled in this instant.

"The undying spiritual light," Luo Zu sighed.

A new plan had already formed in my mind.

The true spirit reflects the undying primordial spirit in order to observe its shape and structure.

The undying primordial spirit has reached an inconceivable realm, so when it manifests in a higher dimension, many strange phenomena are born. It is as if heaven and earth were born in this higher dimension, which is neither thought nor force nor emptiness nor matter nor the Dao, and it is as if all kinds of matter and energy are formed in this space.

Each space resembled a chicken egg, as if a great being was nurturing within it. Then, with a loud boom, the chicken egg-shaped space expanded and exploded, from which emerged an indescribable being, which then carved out illusory universes on the spot.

Luo Zu was naturally used to this scene. Such phenomena frequently occurred after his primordial spirit and true body entered this seventh dimension. They were constantly seen and heard.

There is actually an explanation for this phenomenon. It is because this dimension is now having some difficulty in supporting him, which has caused so many anomalies. This is to push him to a higher dimension.

However, given Luo Zu's current level of cultivation, he would find it difficult to reach the eighth dimension, so he would have to endure the bombardment of the seventh-dimensional phenomena for now.

It was a bit noisy, but it was also much more lively and offered a different kind of scenery, which was much better than the deathly silence of the seven dimensions.

However, such an anomaly does not usually occur. Normally, it is a scene of golden lotus growing in fire and a Dao Lord being born from the golden lotus. Today is special because Luo Zu took his immortal primordial spirit out of his physical body and made direct contact with the seventh dimension, which resulted in this phenomenon.

The basic structure of the immortal primordial spirit has not changed much. It is still a combination of the form of uncertainty and the original form of Luo Zu, forming a structure of infinite and uncertain change in the universe. This structure can quickly and accurately decompose information and then analyze various causes and processes.

The Undying Primordial Spirit adds Undying Aura to this foundation, enabling each wisp of cloud with uncertain probability to carry more information and to delve deeper into the realm of existence and non-existence.

The mysteries contained within were immediately understood by Luo Zu, since his true spirit was in a higher position of observation and had the primordial spirit universe as his thinking brain, and its calculation ability was even greater than that of the current undying primordial spirit.

"On another note, if we're going to use the undying primordial spirit as the structure of the primordial spirit's brain, then it would be better to use the primordial spirit universe as the structure of the primordial spirit's brain." At this moment, Luo Zu wanted even more.

In this way, a Dharma-image brain would have the structure of a primordial spirit universe, which would consume a huge amount of energy and require even more mental strength to maintain. Even Luo Zu's current Taiyi realm mind would not be able to support such a huge amount of mental strength.

He thought the idea was absurd, but it didn't seem impossible to cultivate only three or four primordial spirit universe versions of the Dharma body brain.

Then you can reflect that quality is more important than quantity, and that striving for excellence is not about having as much as possible.

Just as Luo Zu was calculating back and forth, he suddenly felt a throbbing in his heart.

His inner sea is still hidden within his undying primordial spirit, and it is undergoing dramatic changes as his cultivation level increases.

The myriad heavens of the mind are being reflected in the universe, spreading across the vast and diverse primordial world.

During this period of evolution, he suddenly sensed an unusual information appearing in the myriad realms of his mind.

Although this unusual information came suddenly, Luo Zu was able to locate it very quickly.

"Ascension?"

No, it's a reverse ascension. A "person" has ascended from the primordial main universe to the myriad heavens of his mind.

However, calling this ascension an ascension is somewhat inappropriate; it should be described as an exploration, an invasion.

It's like those primordial golden immortals exploring the vast universe, except these "ascended beings" from the myriad heavens of their hearts are only at the level of true immortals. (End of Chapter)
