Shennong Sequence

Moreover, if things escalate and they become outcasts of their families, these aristocratic disciples will lose the most important 'family fortune' in this lifetime!
Therefore, Zhao Yun spent a carefree year in the treasure vault, basically listening to the incompetent barking of outsiders, but no one dared to come and disturb him.

Another six months have passed quietly.

Zhao Yun also stayed at the Daogongku (a type of martial arts storehouse) and didn't go out much.

He hardly ever even went to the Imperial Immortal City.

Instead, he devoted himself entirely to his spiritual practice.

Furthermore, about half a month ago, the surface of this physical body was completely fused and enhanced by the material of the world boundary, forming a special physical boundary!

This special 'physical barrier' can be passively and permanently fixed within a millimeter of the body's surface, thus neutralizing many sneak attacks and other methods!
When this 'physical barrier' is actively activated, a layer of void barrier can be formed on the body surface, which is interwoven with five colors and finally turns into nothingness. It can block stronger attacks, curses, and even some invisible causes and effects, and shield the secrets of heaven!
In addition, through this 'physical barrier', one can also suppress one's own body, slow down the loss of physical lifespan, and even help oneself absorb the continuous spiritual energy of heaven and earth to refine magic power and accumulate it in the inner world, or suppress one's own injuries, etc.!
Therefore, at this stage, the world boundary of the first realm of Foundation Establishment is complete. Next, this world boundary needs to be slightly reshaped and transformed into a bronze furnace for further cultivation in the following realms...

Afterwards, Zhao Yun spent half a month shaping the world boundary on the surface of his body, transforming it into a bronze furnace when in use.

Thus, this world bronze furnace, condensed from the boundary of the physical world, can assist in one's own cultivation, in alchemy, or even in imprisonment and suppression.

Only when one reaches the World Bronze Furnace stage can one be considered to have completely completed the first stage of the Great Dao Foundation Building!
The next stage is the second realm of Foundation Establishment: Dragon and Tiger Intercourse, also known as Water and Fire Harmony.

And there is a song that says:
When water and fire meet, tigers encounter dragons; when the golden old man and the beautiful woman vie for supremacy.

Green goes, white comes, then black, then red enters the yellow palace.

In this realm of Dragon and Tiger Intercourse, there is not much difference between Foundation Establishment of the Great Dao and other Foundation Establishment cultivation methods.

It's simply a matter of the strong tempering yin and yang, and the weak tempering the fusion of water and fire. Furthermore, they ignite a great fire in the Golden Cauldron or World Bronze Furnace cultivated in the first stage of Foundation Establishment, as a more important state of cultivation to follow.

At the same time, such a great fire also tempers the cultivator's physical body, and can also be used for battle, etc. It can be regarded as a process of cultivation blessing and protection in the cultivation path...

Therefore, after Zhao Yun quietly advanced to the second stage of Foundation Establishment in the treasure mine, he didn't rush to cultivate on his own.
Instead, he planned to find Xin Ruyin and use the "Golden Elder and the Charming Maiden Competing for Supremacy"—a shortcut to cultivation described in the Daoist song that also aligns with the principles of the Great Dao—to refine pure Yang and pure Yin, and then introduce them into the world's bronze furnace to ignite the Yin-Yang Fire of Creation!
In addition,

Over the course of more than a year, Zhao Yun has gained a completely new understanding of the cultivation of "The Great Dao Golden Register Chapter: Dividing the Soul, Nourishing the Spirit, and Gathering All Beings"!

Furthermore, based on this 12-zhang inner world, he condensed 12 Other Self Seals!

These imprints of self and others directly resonate with Zhao Yun himself, enabling his soul to move within the self and others, carrying his inner world and origin.

These 12 Other Seals mean that Zhao Yun will have at least 12 chances to revive! However, these Other Seals have not yet found a suitable user.

Furthermore, these Other Seals are born from the Dao rhythm and inner world essence nurtured within the Dao Chapter. They can be released and naturally retrieved at any time, making them more convenient than the previous Beast Seals.

Furthermore, Zhao Yun also discovered a little bit about the method of creating clones, which is a lower level than 'himself'.

The most important module is to split the soul and then find suitable bodies or rare and precious materials to refine the clone.

However, these created clones only have a weak spatial and temporal positioning, and according to Zhao Yun's verification, the positioning and teleportation distance of these clones is not far, with a limit of only twenty miles!
At the same time, this twenty miles is also the limit of the distance for controlling these clones, far from the kind of boundary state described in "The Great Dao Golden Register Chapter: Dividing Souls, Nourishing Spirits, and Gathering All Beings" that can directly cross the infinite worlds and connect with the gods.

However, this is only Zhao Yun's initial stage of cultivation, and this clone control state within a twenty-mile range is quite suitable under various circumstances.

Furthermore, Zhao Yun also possesses those 12 'Seals of Others', which allow him to control clones separately, essentially using his other self to control clones from a greater distance...

However, creating a clone ultimately requires splitting one's soul, which is extremely unfriendly!
After verifying the ineffectiveness of the clone, Zhao Yun withdrew the divine soul from the clone, leaving only himself.

Therefore, after Zhao Yun left the pass, he went directly to Xin Ruyin's side.

Firstly, it is for the cultivation of the second level of Foundation Establishment, namely the Dragon-Tiger Intercourse and Yin-Yang Harmony.

Secondly, Xin Ruyin happens to be from the lineage of all beasts and has a great deal of knowledge about many special spirit beasts.

Therefore, Zhao Yun wanted to find some powerful spirit insects, Gu insects, or some special and extremely powerful spirit beast species from Xin Ruyin to refine the carrier of the 'Other Self Seal'.

After all, the more unique an individual is, or the more adaptable an individual is, the stronger its life characteristics are.

Then Zhao Yun's life-saving method, formed by the material transformation technique and the Great Dao Chapter, will become even more powerful.

So, when Zhao Yun and Xin Ruyin went on vacation together to relax, Zhao Yun talked about refining these 'other selves' that possess absolute control and independent self-awareness.

Xin Ruyin also considered that the 'other self' she was refining could not be limited to the present ancient time and space, but also took into account some states in a future time and space.
Therefore, Xin Ruyin suggested that while ordinary clones might be somewhat useful in this ancient timeline, they wouldn't be able to survive in the future timeline. Instead, it would be better to make good use of the 12 'Other Self Seals'.

The goal is to find special spirit insects that can grow stronger over time, or those with extremely strong survivability that can resist the end of the Dharma era, withstand extreme conditions of heaven and earth, or remain dormant for long periods—these are unique spirit insects and beasts from ancient times—to serve as objects for the 'Self-Seal' to control or even assimilate.
