Shennong Sequence

Furthermore, although Zhao Yun intended to use the material transformation method to explore the true material and spiritual structure of the immortal veins,
However, this Wanling Immortal Mountain is located in one of the four main branches of the sect. Not to mention that you can go underground to observe the immortal branch, if you dare to use earth-遁 (earth-遁 is a type of escaping technique) or other irregular behavior in this place, the immortal arrays covering the mountains and fields can kill a Foundation Establishment cultivator in an instant!
Therefore, one can examine the immortal veins in such places, but only through legal and compliant means.

Since Zhao Yun lacked both background and strength, he naturally couldn't access the immortal veins through legitimate means, so he had to give up for the time being.

He then returned to his dwelling in the Five Elements Immortal Mountain. After looking at his junior sister, he entrusted all the spiritual plants he had planted to her for her to manage, or to consume, so that they could accumulate power for cultivation and growth.

In addition, although Zhao Yun was given the position of guarding many spiritual materials and treasures at the Dao Gong Treasury of the Second Imperial Immortal City, he was not in a hurry to take up the post. Instead, he planned to cultivate in the Foundation Establishment stage for a period of time in the Five Elements Immortal Mountain.

When Zhao Yun previously transformed his inner vision from a false illusion into a true inner world, he could only be considered to have initially stepped onto the edge of the Foundation Establishment realm.

Now, he has begun his cultivation towards the first stage of the Foundation Establishment realm: the Golden Cauldron.

“In those originally normal Foundation Building methods, even if one enters the Foundation Building realm, it is merely a process of continuously accumulating more cultivation, and the illusory inner landscape will not transform into an inner world.”

"Therefore, those Foundation Establishment cultivators below the Great Dao Foundation Establishment stage, in the first stage of Foundation Establishment: the Golden Cauldron realm, cultivate by taking the entire inner landscape as the foundation, shaping it into a cauldron that can bear all of their own power, and then engraving many Dao patterns on it, connecting them into an array, transforming it into an inner landscape cauldron that can devour, refine, and bear all energy!"

"Then, expand the inner realm cauldron to the point where it can cover the entire body and completely overlap with the physical body. When the physical body being cultivated also has this effect, it is the first stage of Foundation Establishment, the Golden Cauldron Perfection. This is the initial state of refining the human body into a golden elixir by using the entire physical body as a golden furnace."

"Therefore, the entire Foundation Establishment stage is actually a prerequisite for the Core Formation stage..."

"But this is below the Foundation Establishment stage of the Great Dao. The inner realm still exists in the first stage of Foundation Establishment: the cultivation process of the Golden Cauldron."

"But what I'm building is the foundation of the Great Dao, so the cultivation steps of this ordinary first stage of foundation building: the Golden Cauldron, conflict with my inner world."

After all, the difference between the inner landscape and the inner world is quite significant. Although the inner landscape is a secret realm of the physical body, it exists in the realm of illusion; while the inner world condenses a true material form, capable of existing among real matter, transforming into nothingness, and even bearing a great deal of spatial power, storing some physical matter—all of these are possible.

"Therefore, to complete the first step of the Foundation Establishment Realm, the Golden Cauldron, the fundamental cultivation of this Great Dao Foundation Establishment requires re-embedding this inner world, which can be independent of the physical body, into the physical body, and using the power of the inner world's boundary to cover the surface of the physical body."

"Then, guided by the boundary of the inner world, a layer of world boundary material gradually emerged on the surface of my Foundation Establishment physical body, thus transforming the entire physical body into a special state of a 'physical world bronze furnace'."

"Furthermore, because this layer of world boundary is fused into the body, it can further strengthen the Foundation Establishment cultivator's resistance to all external forces."

Even when the physical body possesses the full power of a world boundary, attacks below the limits that the body can withstand will be perfectly neutralized by this boundary, thus achieving the ability to defend against attacks below a certain limit without injury!

"This can be considered another form of high-dimensional suppression by powerful beings over cultivators of lower realms!" Besides, the world boundary formed by the physical body through the inner world has even more wonderful uses!
For example:

It can seal away one's own lifespan, reducing the continuous erosion of one's lifespan by time!

The lifespan of a Foundation Establishment cultivator is normally only three to five hundred years, but after being sealed by the physical world's boundary, this time can be extended by at least double, reaching a lifespan of a thousand years.

Therefore, every step taken in this cultivation process is a process of the strong becoming stronger...

Other self-sealing techniques can be developed and utilized based on individual cultivation methods, conditions, and personal choices…

Furthermore, the world boundary inherently possesses the ability to refine external forces, which has many miraculous effects in assisting the growth of one's own magical power, the transformation of the physical body's origin, and so on!
In short, the first stage of the Foundation Establishment realm, the Golden Cauldron, is not only for continuously laying the foundation for the Golden Core realm, but also for deepening the Foundation Establishment realm and the process of the Foundation Establishment realm's power system.

Therefore, Zhao Yun quietly stayed in the Five Elements Immortal Mountain, absorbing the immortal spiritual energy. Through the secret method of differentiating the world boundary in the "Ten Thousand Spirits Return to One Heaven Sutra", he separated a part of the world boundary material in his ten-zhang-wide inner world and slowly fused it with his physical body.

Two months have passed quietly.

While absorbing the immortal energy, Zhao Yun also condensed the matter of the world boundary within his body, thus completing half of his cultivation.

Meanwhile, the Dao Gong Treasury of the Earthly Realm in the No. 2 Imperial Immortal City was urging him to take up his post.

Therefore, he could not delay any longer, so he bid farewell to his junior sister and headed towards the No. 2 Immortal Imperial City to take up his post!
Furthermore, since the foundation of the Great Dao has been established, this flying technique has evolved from the Five Elements Clouds into the Five Elements Escape Technique!

Whether it transforms into a wisp of air in the sky or uses the power of countless trees to quickly unleash Wood Release, its speed is incredibly fast.

The Five Elements Immortal Mountain is a thousand miles away from the No. 2 Imperial Immortal City, but it only takes a quarter of an hour to arrive!

"Young Master has quite the refined taste, dragging it out for two months, causing the Dao Gong Treasury to keep urging you to come." Xin Ruyin made a special trip to pick up Zhao Yun after receiving news of his arrival in the Immortal City.

"Isn't this for the sake of cultivation? That's why I wasn't in a hurry to take up my post. Besides, have you inquired about the position I'm going to in the Dao Cultivation Treasury: the Treasure Mine Treasury? Is there some huge pit waiting for me?"

"I heard there used to be one, but the previous one, upon hearing that the newcomer was a Foundation Establishment cultivator, voluntarily spent money to fill the hole he left behind... When the time comes, you just need to go through the entire process, check the resources in the treasure vault under your jurisdiction, and if everything is correct, there won't be any problems."
