Inside the Small Space, Zheng Yi continued to refine the Celestial Demon Relic, temper the Divine Soul Puppet, and using the connection between the two, he continuously perfected the Nine Heavens and Ten Earths Divine Thought Celestial Strike Technique that had already merged into one.

On the other hand, taking advantage of this free time, Zheng Yi also quickly broadened his knowledge, rapidly absorbing the system of knowledge.

He is like a massive sponge that had been dry for a long time, madly absorbing the rain of knowledge, like finding sweet nectar after a long drought, gaining increasingly deep insights.

Time and again, he relentlessly reshaped his cultivation system, correcting gaps, completing his personal Dao; for Zheng Yi, this was an invaluable experience.

Among them, especially the books describing Core Formation, opened a door for Zheng Yi, allowing him to understand the Dao of the Golden Core more clearly, and paved the way further according to the cultivation system he carried.

Unlike others, although Zheng Yi is currently at the Middle Stage of the Purple Mansion in terms of Magical Power, due to using the Super Brain Main God’s deductions, his accumulation is extremely profound, and he can be considered as high-standing.

Furthermore, with the evolution of the Divine Soul Puppet, every understanding happens in one go, with mutual verification, allowing him to further improve himself.

During this process, Zheng Yi slowly gained a detailed understanding of the description of ’Golden Core’ levels.

Unlike Qi Cultivation, Foundation Establishment, and Purple Mansion, which are the foundational levels, in the Golden Core Level, cultivators were divided into entirely different ranks.

Cultivation is difficult, more difficult than ascending to the heavens.

The higher you go, the differences in the systems and resource accumulation each carries make the achievements in the Dao of the Golden Core vary tremendously.

The tiers here refer to even after breaking through the Golden Core Zhenren Level, the condensed Golden Core also varies in quality.

It could even be said to be as different as heaven and earth.

After reaching the Golden Core Level, although they are all Core Formation Zhenren, the levels of the Golden Core forged greatly restrict the future opportunities, which are already set and fixed.

Therefore, although they are both Core Formation, and they refer to each other as Dao companions, there is a vast difference in both status and actual combat power.

Unlike the first three cultivation levels which are foundational grades, this foundation will undoubtedly emerge after entering the Golden Core Level.

According to different Core Formation Levels, the Golden Core is divided into nine grades.

These are then clearly divided into Lower Three Grades, Middle Three Grades, and Upper Three Grades.

Ninth Grade is the strongest, First Grade is the weakest.

And different grades of Golden Core represent the probability of breaking through to the higher Nascent Soul Stage in the future.

The Lower Three Grades, namely First Grade, Second Grade, and Third Grade, the Core Formation Zhenrens of these grades have almost no chance to advance to Nascent Soul, with probabilities being only one in a thousand or even one in ten thousand.

From ancient times, in the legends passed down to today, those of Lower Three Grades who strike for Nascent Soul are extremely rare and successful.

Those that are also just legends.

Therefore, Core Formation cultivators of this grade are also called Void Core.

These represent the mythical imaginary core, the meaning contained within it is self-evident.

As for the Middle Three Grades, Fourth Grade, Fifth Grade, and Sixth Grade, the success rate is much better than the Lower Three Grades, improving to about one percent.

Cultivators of this grade range are called True Core.

Having further potential for advancement.

Among a hundred Middle Three Grade Core Formation Zhenrens, roughly one or two can succeed, such cultivators are already outstanding among them.

While Upper Three Grade cultivators are called Golden Core cultivators, holding the highest status and strongest combat power.

It’s said that Ninth Grade Golden Core cultivators are also called Nascent Soul Reserve, with the greatest chance of advancement, it’s almost certain that entering the Nascent Soul Stage is a natural progression, no obstacles can prevent it.

Lower Three Grades, Void Core.

Middle Three Grades, True Core. 𝚏𝕣𝕖𝚎𝚠𝚎𝚋𝚗𝐨𝐯𝕖𝕝.𝕔𝐨𝕞

Upper Three Grades, Golden Core.

This is the current division of the levels for Core Formation Zhenren, but achieving Upper Three Grades Golden Core Zhenren is as difficult as climbing to the heavens, requiring prowess, opportunity, and resources, without which it’s one in ten thousand.

Even within the historical heritage of the Three Desolate Mountain Range, it’s generally only once every eight or nine hundred years that an Upper Three Grades Golden Core Zhenren might appear.

And determining the grade of the Core Formation Zhenren’s Golden Core lies in the cultivator’s own accumulation of resources, ultimately condensing and transforming the perfected personal Dao, which represents the Innate Divine Power Seed.

According to the Daoist Canon, by Zheng Yi’s understanding, this Innate Divine Power Seed is the rule of power transformed by the perfected personal Dao.

Divine Techniques themselves are the embodiment of the heavenly rules.

And being able to transform into Innate Rules and condense into the Divine Dao Seed is the foundation of a perfected system.

One Dao Seed represents the First Heaven.

Nine Divine Dao Seeds form Ninth Grade.

In легендарные Ninth Grade Golden Core cultivator, each must grasp at least nine Innate Divine Techniques, making their combat power unimaginable.

At the Late Stage of Core Formation, they can even be called Half-Step Nascent Soul, where the strength can be imagined.

The stronger the Divine Techniques, the higher the grade they achieve post-Core Formation, and the greater the chance of advancing to the Nascent Soul Stage.

"Hmm?!"

After combing through the Golden Core levels, Zheng Yi unexpectedly discovered something unique that the Divine Thought ancestor left in the Daoist Canon.

A hand-drawn map of a Secret Realm!

This map is drawn extremely carelessly, as if sketched casually, the material used is rather ordinary, just a piece of beast hide, with nothing special about it.

But it was kept in the most core area of the Daoist Canon, and if not for Zheng Yi now being the half-owner of the Celestial Demon Relic, he could not have possibly discovered the existence of this Secret Realm map.
