Three days later, at the Lin residence within the Imperial City of Luojing, Lin Rui was practicing the Pile Technique in the martial arts training ground.
The "High-level Ling Huan Pile Technique" that he had exchanged from Battle Spirit No. 2 made the Qi and Blood in Lin Rui's body surge. It deeply integrated with the Primordial Spirit in his brain marrow, facilitating the extraction of strength from his Qi and Blood, thereby nourishing and strengthening it.
At the same time, Lin Rui's entire body 'crackled and snapped', as his muscles, bones, meridians, blood vessels, and fascia were being stretched to their limits and rapidly repaired under the unique circulation of Qi Yuan.
This is essentially a high-level Pile Technique originating from Ling Huan, primarily cultivating the Divine Soul and secondarily strengthening the flesh. The effects were very good, ranking among the top-tier in high-level Pile Techniques.
