Su Jie was controlling the strengthening of the thousand-hand centipede with ease, having had multiple experiences, he was now well-versed in this process, and he planned to do another thing.
"Wife, help me protect the law."
Su Jie said to Han Ruyan.
Han Ruyan didn't speak but simply waved her hand to create a number of papermen, while also releasing the Mirror Girl and the Lantern Ghost.
After Su Jie had set up the formation to ensure protection, he took a deep breath, and his Primordial Spirit leapt out from the top of his head in an instant.
Looking at it now, Su Jie's Primordial Spirit was as big as Su Jie's physical body, without any difference.
Initially, the Divine Soul was only a ball of light; at this stage, a Cultivator strengthens the Divine Soul by making the ball of light grow limbs and facial features.
Upon completing this step, one could achieve the Primordial Spirit, which at that stage looked like a baby, only a few dozen centimeters tall and very cartoonish.
The process of strengthening the Primordial Spirit involved transforming from the baby form, gradually maturing until it was indistinguishable from a real person, perfectly unifying the Primordial Spirit with the physical body.
This state of the Divine Soul was then known as God Unification, signifying the unity of spirit and flesh, with the Primordial Spirit corresponding to the physical body.
Typically, only upon breaking through to the Taoist Platform Realm, one could complete the God Unification—a very mysterious domain, accessible only at the Taoist Platform Realm.
However, after devouring a great deal in the Tao River, Su Jie's Primordial Spirit had already grown to be indistinguishable from his physical body.
That also meant that Su Jie's Primordial Spirit was complete and ready to make the breakthrough into the God Unification Domain.
Above the Primordial Spirit, countless points and lines of light appeared internally.
Upon closer inspection, these points and lines of light corresponded to the acupoints and channels of Su Jie's physical body.
The next moment, Su Jie's Primordial Spirit dove back into his body.
A massive amount of Soul Power began to scan Su Jie's body, recording every change of his physical body one-to-one into the Primordial Spirit, achieving perfect coordination and unity.
In the process, after the Primordial Spirit returned to its cavity bringing along immense Soul Power and flushing through the limbs and bones, corresponding one-to-one with the physical body.
Su Jie's body began to change as well; stars began to shine through from his flesh and blood.
The jade-like Divine Marrow and pale golden Spirit Blood within Su Jie, every cell in his body jubilant, absorbing the feedback from the Primordial Spirit.
In just a few dozen breaths' time, the kidney area inside Su Jie's body, like a fusion point successfully ignited, radiated endless brightness, overshadowing the starlight of the acupoints, and with the sound of surging tides, Su Jie began to attempt to cultivate his kidney area into an inner god.
The Kidney is Water, and when Su Jie began to refine his kidney area, his kidneys emitted a vast ocean-like blue halo, lighting up the entire underground space, making it exceptionally clear.
The Primordial Spirit and physical body interact with each other, with a strong body being able to strengthen the Primordial Spirit.
Similarly, the growth of the Primordial Spirit can also nourish and enhance the physical body.
An hour later, a gigantic pond had formed under Su Jie's feet, condensed from the water in the environment, a natural phenomenon that occurred when the Kidney Body God was being formed.
Su Jie was sitting cross-legged above this pond when gradually, waves began to stir on the surface.
Even though there was no wind in the underground space, the pond, like the ocean, began to churn, sending wave after wave crashing against the surrounding soil.
A fountain jetted from the pond, and Su Jie soared into the sky along with it.
The fountain flowed and surged under Su Jie's feet, propelling him into midair.
With a light clench of his fist, the air exploded, and the water droplets scattered in all directions, each one like a bullet, leaving the surroundings riddled with holes.
And the water kept flowing, as if it would never be exhausted.
The Kidney is Water, and when the Kidney Body God was unleashed, the endurance of the Spiritual Power could be increased.
Considering the upcoming Sect war, Su Jie chose to refine the Kidney Body God to give himself more combat endurance.
At this point, Su Jie had successively refined his heart, lungs, and kidneys, enhancing burning damage, armor-piercing damage, and endurance respectively, preparing himself for the Sect War.
"Secret Storage Three Level Realm, Kidney Water God!"
A smile appeared on Su Jie's face, his cultivation realm, with the activation of the Kidney Body God, had also reached the Third Level of Secret Realm.
Without the feedback from the Primordial Spirit, it would have been impossible for Su Jie to advance to another cultivation realm in such a short period of time.
When Su Jie's physical body made a breakthrough, the Primordial Spirit also finally completed the collection of all the microscopic details of the body, leaping out above his head again, sitting in the void, with a red cloak fluttering behind the Primordial Spirit, lending Su Jie's Primordial Spirit a majestic and awe-inspiring presence, as Su Jie prepared for the final breakthrough.
Having gained so much from the Tao River, Su Jie's breakthrough was exceedingly smooth, coming naturally like a river flowing into a channel.
Su Jie could vividly feel the changes in his Primordial Spirit.
As more and more acupoints and channels densely emerged on the Primordial Spirit, countless microscopic structures formed, rapidly solidifying the texture of Su Jie's Primordial Spirit.
If one had looked at Su Jie's Primordial Spirit in the past, there would be a sense of illusion, akin to viewing a person through 3D virtual reality technology; even if their appearance was exactly the same, one could tell at first glance what was real and what was not.
But now, as acupoints and channels were filled in, Su Jie's Primordial Spirit became more and more realistic.
Even breathing, pores, body temperature, and heartbeat reproduced one by one, which is indicative of the God Unification Realm.
Now, if an ordinary person were to look at Su Jie's Primordial Spirit, they wouldn't be able to tell it apart from a real person at all.
"God Unification Domain, achieved."
A glint of joy flashed in Su Jie's eyes, feeling refreshed, as the Primordial Spirit of the God Unification Realm wasn't just solid in appearance, its power had also greatly increased.
